J. Craig Venter, Ph.D. is a leading scientist in the field of genomic research. He is also the founder and CEO of Synthetic Genomics Inc., a privately held company dedicated to “commercializing genomic-driven solutions to address global needs such as new sources of energy, new food and nutritional products, and next generation vaccines.”

He and his research team have been field-testing technology that he believes will revolutionize the search for extraterrestrial life. According to the South China Morning Post, “Not only does Venter say his invention will detect and decode DNA hiding in otherworldly soil or water samples – proving once and for all that we are not alone in the universe – it will also beam the information back to Earth and allow scientists to reconstruct living copies in a biosafety facility.” He hopes to detect Martian life and bring it to Earth using a digital biological converter, or biological teleporter.

The India Times describes, “Dr. Venter’s machine would merely create a copy of an organism from a distant location — more like a biological fax machine.” Storing genetic code in a computer and transmitting it just like any other data is the basic idea.

Dr. Venter’s team, and scientists from NASA’s Ames Research Center, recently conducted field-testing of this technology in the Mojave Desert south of Baker, California–a dry environment similar to Mars. Researchers tested the unit that would, in theory, send data back from Mars. But according to Dr. Venter, a prototype of the unit that would receive the transmitted data here on Earth exists as well, and will be available for sale next year.

India Times explains that this machine will be able to “automate the synthesis of genes by stringing small pieces of DNA together to make larger ones.” With this technology, “A person with a bacterial infection might be sent the code to recreate a virus intended to kill that specific bacterium.” Venter optimistically surmises that this technology will enable doctors to “send an antibiotic as an email,” and allow diabetics to “download insulin from the Internet.”

Possible Life Before Earth

From arxiv.org:

An extrapolation of the genetic complexity of organisms to earlier times suggests that life began before the Earth was formed. Life may have started from systems with single heritable elements that are functionally equivalent to a nucleotide. The genetic complexity, roughly measured by the number of non-redundant functional nucleotides, is expected to have grown exponentially due to several positive feedback factors: gene cooperation, duplication of genes with their subsequent specialization, and emergence of novel functional niches associated with existing genes. Linear regression of genetic complexity on a log scale extrapolated back to just one base pair suggests the time of the origin of life 9.7 billion years ago. This cosmic time scale for the evolution of life has important consequences: life took ca. 5 billion years to reach the complexity of bacteria; the environments in which life originated and evolved to the prokaryote stage may have been quite different from those envisaged on Earth; there was no intelligent life in our universe prior to the origin of Earth, thus Earth could not have been deliberately seeded with life by intelligent aliens; Earth was seeded by panspermia; experimental replication of the origin of life from scratch may have to emulate many cumulative rare events; and the Drake equation for guesstimating the number of civilizations in the universe is likely wrong, as intelligent life has just begun appearing in our universe. Evolution of advanced organisms has accelerated via development of additional information-processing systems: epigenetic memory, primitive mind, multicellular brain, language, books, computers, and Internet. As a result the doubling time of complexity has reached ca. 20 years. Finally, we discuss the issue of the predicted technological singularity and give a biosemiotics perspective on the increase of complexity.

A very fine paper, except for one thing.

The authors only use one data-set to reach their conclusions.

And I believe they are wrong unless they can prove we live in a simulated universe.

The UFO “Solid Light” Phenomenon

From Science and the UFO CONTROVERSY:

This picture was produced by my son Chris with my assistance to develop imagery that helps describe a “solid light” case that was focused at a beach headland area at Kiama New South Wales in Australia back in the early 1970s. I have revisited this affair many times and it has inspired my worldwide focus on similar cases. Gildas Bourdais from France helped me immensely with regard to the strange event played at Taize back in 1972. I have also focused on the classic Trancas case from Argentina in 1963. Both cases are striking, but not without their weaknesses and possible explanations. In both cases my enquiries to date suggest the possible explanations are not all that compelling, but we still need to examine them, to see how the evidence for these classic cases stack up.

An objective and solid evidence based focus on the role military and government has emerged with the appearance of the book “UFOs and Government – A Historical Inquiry” by the UFO History Group, the primary authors being Dr. Michael Swords and Robert Powell, and contributions from the rest of the group – Clas Svahn, Vicente-Juan Ballester Olmos, myself (Bill Chalker), Barry Greenwood, Richard Thieme, Jan Aldrich and Steve Purcell.
One of the major themes that runs through the “UFOs and Government” narrative is the recurring sense of lost opportunities to engage appropriately with a consistently unexplained phenomena, which if studied properly could yield fascinating scientific breakthroughs.  When the picture presented is of poor investigation and active debunking with far too little serious in depth analysis, and yet we have impressive international evidence of a consistent unexplained phenomenon, there is a vast disconnection from an appropriate scientific response.
The book “UFOs and Government” alludes to several lost opportunities to focus on enduring unexplained attributes of the UFO phenomenon.  Unfortunately if your only insight into the UFO phenomenon was the typical debunking official military response revealed time and time again by their documents and histories, you would miss these strange and possibly breakthrough attributes of the UFO phenomenon.
A striking example of this is the fascinating 1960 Red Bluff California case where official attitudes caused a UFO witness, a highway patrol officer, to not initially describe the “light beam projected by the object seemed like what would be described today, as a big, fat laser beam.  That is, it did not spread out or diffuse “properly.” But worse than that, the beam seemed to have an “end” to it,” wrote Mike Swords.  Here was a remarkable example of what many researchers have called “solid light” in action.  In writing this Dr. Swords touched upon a critical issue.  He highlighted that Dr. James McDonald did manage to draw out this remarkable detail, because he was actually interested in what the witnesses reported, rather than conducting a myopic debunking exercise.  Genuine scientific skepticism, driven by a desire to question and carefully investigate an experience can potentially yield scientific breakthroughs. We now know that there are many such cases of “this peculiar sawed-off light” or “solid light.”
Indeed Michael Sword’s indicated in an endnote in “UFOs and Government” that “sawed-off light” cases are “a peculiar feature of a smallish set of “high strangeness” UFO encounters.  As these encounters are widely spread across the world, this feature is suprising and difficult to explain on sociological grounds.” He indicated he had some 44 cases in his own files.
I had been studying these sorts of “solid light” cases for decades so I naturally contacted Mike about his collection.
I emailed Mike Swords:
“I have been quietly studying for decades this strange aspect of many worldwide UFO cases and have developed a very disorganised collection of material on such cases.
“In both “The OZ Files” and “Hair of the Alien” I refer to solid light cases and describe an Australian case from Kiama, southern NSW from the early 1970s.  I have been looking into the case since learning of it in the 1990s and earlier this year conducted a very detailed site investigation to determine if the observations reported by the primary witness were possible and to see if further information could be found.  The case is rather complicated and also has entity and abduction aspects.  The primary witness has closely guarded his privacy and I have only had one face to face meeting with him, as well as many phone conversations, written statements and emails.
“The on site investigations this year took place because the main witness was more forthcoming with locational details.  Some of this was in my original interview notes and material when we originally talked in person, however they were not precise enough to undertake an on site reconstruction.  Finally this year these confirmations were forthcoming and I had sufficient detail to locate the exact viewing locations, lines of sight, and confirm accurately the Kiama beach location. I stayed there for 2 days gathering information and managed to confirm that his ex parents in law were still living at the house in question.  The ex father in law while elderly recollected the night, but while he feels he may not remember the event as the main witness Graham described to me, he is certain that his former son-in-law would not have invented the story.  Bill, the ex-father in law, recollects that Graham was agitated and focused on the incident, but Bill cannot recollect that his own involvement was as Graham described it in his accounts to me. 
“Having talked to Graham a number of times over the years I have found him to be a compelling witness, but one who has struggled mightily with the ontological status of the events.  Indeed he was originally much more comfortable casting the event as a strange dream.  While the recent investigations seem to caste the stranger aspects as being witnessed by Graham only with marginal supporting cast in the form of his ex wife and ex father and mother in law, as well as possibly some neighbours, who may have interpreted the event in different ways, this seems to be a strange “display” event, so frequently reported in many CE type cases, particularly those with high strangeness elements, such as this one.  In many of these sorts of cases there often seems to be selective perceptions of the events, sometimes so acute that often people near to each other have a very different experience, as if a central witness is the only intended viewer?
“The ongoing investigation has continued to energise my interest in solid light cases and I have been attempting to drag all my solid light cases together with a view to create a catalogue of such cases, building on the early SOBEPS catalogue of the 1970s.
“I was also intrigued with a UFO film taken by Ray Stanford, covered in Chris Lambright‘s recent e-book “X Descending”.  Because I had some previous contact with Ray back in the 1970s and early 1980s and talked to him briefly at the 1987 Washington DC MUFON symposium, I renewed our acquaintance. This lead to some extensive email exchanges in which he elaborated on the “new film”, beyond the “air spike”/Leik Myrabo connection which Chris has understandably focused on. 
“Instead I focused on a different part of the same footage which appears to show a “solid light” projection event. 
“Apart from many other cases I was also drawn towards a Chinese event I located that occurred in 1998 at a desert Air Force base, involving a Chinese Air Force F-6 pursuit.  The possibly striking confirmation of Zhao Xu, who is described as a famous Chinese Defence expert in unmanned aircraft, as one of the various high level witnesses, who mentioned “Surprisingly these two light beams of light were not as we normally see light beams, as has been according to the distance and spread, but as two light-emitting entities, sticking out from the bottom of the UFO ending on a certain length. At least today we have not got control of this sort of light technology.”  Radar detection was also involved.  Given this comment was made by a defence specialist* I suspect some Chinese military science investigation and research since then.
* Correction: following further research and more detailed translations the quote above referring to “two light-emitting entities” comes from General Li the PLAAF missile base commander in the Badain Jaran Desert in Lanzhou province.  Major General Zhao Xu witnessed the UFO incident.  It was General Li’s pilots who undertook the attempted aerial pirsuits and close up observations.
“Meanwhile open science has been playing with Bose-Einstein condensates et.al to manipulate light in diverse ways – our crude opening gambit in a direction that might show us “solid light” effects that have been reported for decades in a diverse range of international (UFO) case material.  Mainstream science directions in this area have been nicely summarised with references in Sidney Perkowitz‘s “Slow Light: Invisibility, Teleportation, and other mysteries of light” (2011).
“Hence my ongoing deep focus on “solid light” cases and my long winded way of asking if I can get a copy of your 44 “solid light” case files!  A big ask I know, but it would support an in-depth focus on these cases and perhaps a collaborative workup of a catalogue of such cases to build on the early and somewhat flawed SOBEPS catalogue?
“Best wishes in “solid light” anticipation, like don’t keep me in the dark (pun intended),
Bill”
Mike was very helpful and shared his listing of cases.  Indeed he addressed this research focus in his always interesting blog “The Big Study” – thebiggeststudy.blogspot.com – on October 19 2012 – with a post entitled” “SLOW LIGHT & UFOs”:
“Bill Chalker wrote the other day. He’s contemplating making a review of so-called “solid light” UFO cases, and I welcome that. Bill’s a hard-science-trained ufologist and might just be able to make some sense of a real puzzlement in this field. He asked me if I’d scour my files for such cases [since I'd foolishly admitted to having around 44 of such things], and so I did, making a list for him to pursue and build his analysis more robustly [Bill already had a bigger bunch than that].”
Mike further stated, In my understanding the term “solid light” came from witness testimony— the light beam seemed “solid”; it was as if the beam extended like a solid tube, etc. This phrase stuck but is probably a bad one. The light effects that we’re witnessing in these cases behave not like solids but like “regular” light which is abnormally “contained” somehow. Things don’t seem to be “impacted” by these beams, only illuminated by them. The things [generally] seem to be more like spatially-constrained lasers [admittedly of wide diameter] than anything solid, and might well be more like tubes [i.e. hollow] than “full” beams.”
I recommend readers read Mike Swords valuable post on this fascinating group of cases.
I’ve included the core details of the catalyst for this re-invigorated enquiry into “solid light” cases.
BIZZARE UFO “LIGHT” PHENOMENA AT KIAMA
…. I was approached by a man who was troubled by a bizarre episode on the south coast at Kiama, in the early 1970s….  The reporting witness, who I will call Graham, has pondered the nature of what occurred.  He is troubled by it and now feels more comfortable with it being a dream.  The fragmentary nature of the events and the strange elements of the experience beckon this interpretation.  But there are startling aspects that fit in with some extraordinary characteristics of the UFO phenomenon.   I have spoken to Graham on a number of occasions and meet him directly for an extended interview.  I found him to be a compelling witness who is grappling with the ontological issues that striking episodes often force us to confront.  I have quoted from his own prepared statement:
“Awoken by a light coming into the room, I was too drowsy to do anything about it, I wanted to sleep.  It came to mind that the only way light could come into the window was a light was being shone at it.  I thought it may be an intruder so I forced myself awake, to step over the baby and my two year old daughter sleeping on the floor beside me.  When I got to the window I could see nothing unusual outside.  Thinking it must have been a dream because I had remarked on the endless stream of car headlights winding their way along the old highway towards Sydney.  I laid down again and fell quickly asleep.  Again the light came into the room.  This time I jumped up quickly, wide awake again, there was nothing unusual outside.  Suddenly I saw a light beam white in colour with a blue fluorescent tinge evaporating from it.  Because of the luminescence of the light I was able to make out the shape of a flying craft from which the beam projected at an angle to the ground of about 75o. “The beam was about 30 feet long and about 2 feet six inches diameter, given the craft was between the headland I was on and the next headland.  Suddenly the beam, still only 30 feet long fell, like a perfect cylinder of solid light.  It did not fall in the direction of gravity, it continued along the path of its own axis.  The cylinder of solid light hit a caravan.  Upon impact the light behaved like water, pouring over the caravan, over its roof, over its walls, over every nook and cranny of the van.  Like fluorescent paint from an electro, airless spray gun.  The caravan illuminated completely for about three seconds then the light faded away.  My attention was on the light.  I could not see the craft any more.
“I rubbed my eyes and looked for the craft.  It appeared slightly to the left of its original position with another beam of light, descending from it at a very slow speed; say about only 3 feet per second.  When the beam reached a given length, longer than the first time, it began falling as before.  This time it hit an amenities block and the light covered its surfaces completely illuminating it in the same way as the caravan.  Again the light faded away. 
“From the same location, the craft let another beam go at an angle of about 45o to the ground level line.  The beam was much longer than before.  It reached the beach and illuminated approximately an area of sand forty feet at its widest.  Inside the lighted area were two men standing motionless looking up at the craft.  A young woman jumped up from sitting near a small beach fire and ran to stand with the two men.  A second young woman was running backwards trying to brush the light off her arms and body.  Then she too stood separate to the other three and also stared up at the craft.  The light suddenly went out and I looked for the people.  Has it taken the people I thought.  Where as I was marvelling at the craft and light before, I now became angry, thinking it has terrorised that woman.  It was not a good thing as I first thought.  Now I could see the fire dimly glowing.  I looked this way and that to see if any of the people walked in front of the fire, to prove they were still there.  I fell asleep on my feet.  When I awoke I was standing on the other side of the window, one hand on the window.
“I looked outside the window only feet away.  The craft hovered over the street in front of the house.  It manoeuvred very close to the window.  I was impressed that it looked like a spaceship.  It had no helicopter noises or blades.  It did not force itself off the ground.  There was no blowing of the small trees.  It was not a hovercraft, and it had no wings like a plane.  The metallic material it was made of appeared as though it was unpolished Zinc alloy.  It had no seams, no rivets, no weld marks, no plates visible.  It was as if it was made from one piece of metal about 40 feet wide and 10 feet high, which began to spin in one direction, then it stopped and spun for a shorter time in the opposite direction.  Then it stopped spinning, hovering in a steady position above the skyline.  There were no thoughts it belonged to the western world.  That it was a secret craft, that got into difficulty.  That I wasn’t meant to see.  I blacked out.
“When I came to, the craft was still opposite my window.  I thought why was I meant to see that it had no welds or seams, it seemed to want to show me that.  I looked at a window shape about six feet wide and two feet six inches high with carved corners.  The metallic window shield suddenly disappeared and I could see inside the craft.  I saw no fittings.  It had flat vertical off white walls.  I felt very peaciful.  A man walked into the room of the craft and stood in front of the window.  As he walked in he was looking at a flat object he was holding in his hands, like a clip board but thicker.  He began to move his arms as though he was working on something at bench height below the window.  Totally absorbed, he worked away.  I felt completely safe.  Another man then entered the room looking at the other man and what he was doing.  He stood also facing me looking at the bench and pointing like without words he was helping the other fix something.
“They had bright silver one piece suits like thin wetsuits on, with no badges or markings.  They carried no weapons or tools.  The craft had no fittings or anything that looked like a weapon, so I felt safe.  And besides, they didn’t know I was watching them.  With that thought the last one to enter the room smiled at the other, then they both smiled directly at me.  I had physical fright, my hair stood on end literally and I knew what it meant to be really scared.  I dropped to the floor and said, “Everybody keep down. Stay out of the light.”  I knew that in the light they could control my thinking to feel and think peacefully.  Suddenly great noise and severe vibration of the house took place.  The laundry light went dim, the fridge began jumping about and there was great noise above the roof.  The washing machine was bumping about also.  I said, “Quickly get under the doorways, the house is going to fall.”  It was like the craft overhead sucked the electricity out of the house, then took off.
“Bill shouted out, “Shit, what was that?  It took the bloody roof off.”  I said, “It was a UFO.”  Somebody said what, againI said, it was a UFO.  Bill said, “Yes I saw it as it took the roof off.”  Bill was trying to comprehend how come the roof was still there.
“Gordon __  living behind came out to his back door and said very explicitly, “What the …… was that?  I thought it took the roof off.”  He too was greatly concerned with checking out his roof, reassuring himself it was still there.  The lady next door on the seaward side opened a window and said, “Where did it crash?  Do we have to get out?”  She became very angry saying again, “Do we have to get out?”  No you’re safe.  It’s gone.  Relieved, she said, “I am alone with the children tonight, that bloody pilot should be shot for that.”  It was unusual to hear people who I had never heard swear before, swearing.
“Bill and Gordon were saying it was a UFO.  Suddenly, __, Bill’s wife began to try and quieten everyone down and get us all inside.  We decided that I should phone the Nowra base.  I spoke to the duty officer.  He said he was the only one on duty.  He asked me if I saw any orange lights.  I said, “Yes.”  He then quickly said it was a weather balloon you saw, it was let go at such and such a time from Jambaroo, it didn’t inflate properly and other people reported seeing it as an orange light over Kiama.  In my mind I thought, he knows what it was, it must be secret.  I’ve done my duty reporting it, so that was that.
“The next day (our wives) said two men in dark suits with ID tags came to the door asking did any one see anything unusual last night.  Frightened by the men, they said no and the men went on.  (Our wives) warned me not to speak about it, they were very frightened that something would happen to me if I spoke up and also it would make us a laughing stock in the community.  The plan was we would forget it, not talk about it, even to one another.  So it would be distanced from our lives.
“Bill was reading the paper some days later and said an expensive Navy helicopter flew from Jambaroo over Kiama.  It lost its electronics and crashed forty kilometres out to sea off Kiama.  The navy was reported to be trying to recover it to find out what happened.  The crew were rescued.  I said, “Yeh, I know about losing power, the same thing happened to the helicopter as what happened to the fridge and the laundry light.  The UFO took its electricity.”  Nothing was said further.  We ignored the event.  What I saw holds future understanding for me, if it was a dream I believe.  Possibly it was an active imagination, a dream and actual occurrences combined.”
This strange affair has several defined stages, but the evident discontinuities in awareness, argue both for a surreal, dream like quality and also reflect the paradoxical reality of some of the stranger elements of the UFO phenomenon.  The extraordinary behaviour of the “light beams” behaving as both “solid” and “liquid” has been reported elsewhere in Australia and overseas.  The apparent display quality to episodes in the incident is reflected in many cases.  There seems to have been a number of gaps in the time sequence.   The apparent plight of the people on the beach is provocative, and one I am trying to unravel.  This is clearly a case that would benefit from further in depth enquiry.
Fortunately the original witness to the Kiama case re-contacted me.  He has been very difficult to relocate after my original interviews with him.  He is still very guarded about his privacy and protecting the welfare of his family.  However we were able to have some very extensive discussions and a detailed interview where I was able to locate the events much more precisely in the Kiama area and secure more details about the incident.
He confirmed an aspect I had long suspected as part of the experience, which he only original hinted at in the vaguest possible way.  He has an abduction recollection that was consciously recollected at the time, but he was extremely reluctant to share these details during our original discussions years ago.
He recollects sitting in a curved hallway in a strange environment.  He heard a voice and turned to find a woman.  She asked him, “Do you remember what happened in there?”  “No,” he replied. “Do you?” he asked. “Put it this way, I won’t be telling my husband.”
He doesn’t recollect much more, or he volunteered little further detail about this aspect of the Kiama encounter.  However he did say he started to frequent some UFO group meetings with the express purpose of seeing if he could find the woman he had encountered in the Kiama experience.  At one meeting he saw a woman who looked like the woman encountered in the “strange environment”, presumably onboard the UFO.  When he started to talk to her he felt she was not the right person and did not persist with the conversation.

I described some of the results of my 2012 field investigations in the Kiama area in my email to Mike Swords quoted above.  I hope that further research and investigation will continue to assist the evaluation of this strange case.  It will be fascinating if the ongoing enquiries further validate the affair. “Solid light” cases represent an intriguing and challenging opportunity to research a potential “breakthrough” aspect of the UFO phenomenon.  If we can get to the bottom of such extraordinary manipulations of light and other associated UFO light phenomena, then real progress in a UFO science can be made. Maybe mainstream science is slowly catching up. New Scientist has done a few reports on “tractor beam” development following the Bessel beam principle, including this one:

which was accompanied by this Russell Tate/Getty Imagest image:

An earlier New Scientist piece (3 March 2011) highlighted the Chinese connection: http://www.newscientist.com/article/dn20193-treklike-tractor-beam-is-possible.html

(This image accompanied the March 2011 New Scientist article)

Now Jun Chen of Fudan University in Shanghai, China, and colleagues, have shown that it is possible to create exotic beams that would pull rather than push on an object. For tiny particles with dimensions of a thousandth of a millimetre or so, this would result in the particle being drawn back towards the beam.

Hmm … I wonder what inspired them? Perhaps the Zhao Xu and General Li 1998 UFO observation? Seems to me that maybe someone within our more clandestine scientific community is already trawling through “solid light” UFO cases?

The “solid light” phenomenon is gaining scientific value in the laboratory as in the actual “slowing down” of light in crystals and heavy gases using diffuse lasers.

All in all, I think that the answer to the UFO issue lies in finding the answer to quantum entanglement, brane theory and linking of parallel universes at a practical level.

SOLID LIGHTS and the neglected UFO SCIENCE LEGACY

Worldships and Planetary Chauvanism

From Centauri Dreams:

The assumptions we bring to interstellar flight shape the futures we can imagine. It’s useful, then, to question those assumptions at every turn, particularly the one that says the reason we will go to the stars is to find other planets like the Earth. The thought is natural enough, and it’s built into the exoplanet enterprise, for the one thing we get excited about more than any other is the prospect of finding small, rocky worlds at about Earth’s distance from a Sun-like star. This is what Kepler is all about. From an astrobiological perspective, this focus makes sense, as we want to know whether there is other life — particularly intelligent life — in the universe.

But interstellar expansion may not involve terrestrial-class worlds at all, though they would still remain the subject of intense study. Let’s assume for a moment that a future human civilization expands to the stars in worldships that take hundreds or even thousands of years to reach their destination. The occupants of these enormous vessels might travel in a tightly packed urban environment or perhaps in a much more ‘rural’ setting with Earth-like amenities. Many of them would live out their lives in transit, without the ability to be there at journey’s end. We can only speculate what kind of social structures might emerge around the ultimate mission imperative.

Moving Beyond a Planetary Surface

Humans who have grown up in a place that has effectively become their world are going to find its norms prevail, and the idea of living on a planetary surface may hold little interest. Isaac Asimov once wrote about what he called ‘planetary chauvinism,’ which falls back on something Eric M. Jones wrote back in the 1980s. Jones believed that people traveling to another star will be far more intent on mining asteroids and the moons of planets to help them build new habitats for their own expanding population. Stephen Ashworth, a familiar figure on Centauri Dreams, writes about what he calls ‘astro-civilizations,’ space-based cultures that focus on the material and energy resources of whatever system they are in rather than planets.

mann_worldship

Ashworth’s twin essays appear in a 2012 issue of the Journal of the British Interplanetary Society (citation below) that grew out of a worldship symposium held in 2011 at BIS headquarters in London. The entire issue is a wonderful contribution to the growing body of research on worldships and their uses. Ashworth points out that a planetary civilization like our own thinks in terms of planetary resources and, when looking toward interstellar options, naturally assumes the primary goal will be to locate new ‘Earths.’ A corollary is the assumption of rapid transport that mirrors the kind of missions used to explore our own Solar System.

Image: A worldship kilometers in length as envisioned by space artist Adrian Mann.

An astro-civilization is built on different premises, and evolves naturally enough from the space efforts of its forebears. Let me quote Ashworth on this:

“A space-based or astro-civilisation…is based on technologies which are an extension of those required on planetary surfaces, most importantly the design of structures which provide artificial gravity by rotation, and the ability to mine and process raw materials in microgravity conditions. In fact a hierarchical progression of technology development can be traced, in which each new departure depends upon all the previous ones, which leads ultimately to an astro-civilisation.

The technology development Ashworth is talking about is a natural extension of planetary methods, moving through agriculture and industrialization into a focus on the recovery of materials that have not been concentrated on a planetary surface, and on human adaptation not only to lower levels of gravity but to life in pressurized structures beginning with outposts on the Moon, Mars and out into the system. Assume sufficient expertise with microgravity environments — and this will come in due course — and the human reliance upon 1 g, and for that matter upon planetary surfaces, begins to diminish. Power sources move away from fossil fuels and gravitate toward nuclear and solar power sources usable anywhere in the galaxy.

Agriculture likewise moves from industrialized methods on planetary surfaces to hydroponic agriculture in artificial environments. Ashworth sees this as a progression taking our adaptable species from the African Savannah to the land surface of the entire Earth and on to the planets, from which we begin, as we master the wide range of new habitats becoming available, to adapt to living in space itself. He sees a continuation in the increase of population densities that took us from nomadic life to villages to cities, finally being extended into a fully urbanized existence that will flourish inside large space colonies and, eventually, worldships.

An interstellar worldship is, after all, a simple extension from a colony world that remains in orbit around our own star. That colony world, within which people can sustain their lives over generations, is itself an outgrowth of earlier technologies like the Space Station, where residence is temporary but within which new skills for adapting to space are gradually learned. Where I might disagree with Ashworth is on a point he himself raises, that the kind of habitats Gerard O’Neill envisioned didn’t assume high population densities at all, but rather an abundance of energy and resources that would make life far more comfortable than on a planet.

 

This reminds me of an old Analog article I read back in the 1970s by Larry Niven titled “Bigger Than Worlds” in which Niven gave several examples of structures that evolved into massive structures from interstellar vessels to Ringworlds and Dyson Sphere, all of which were safer than natural planets.

Of course this goes by the assumption if human goes by the “expansion” route, or the “evo devo” route proposed by Jon Smart.

Toward a Space-Based Civilization

 

 

The Invisible Invaders

From starpod.us:

(STARpod.us) — Imagine this, then pretend it isn’t real.

Professor Stephen Hawking was right, contact with an extraterrestrial alien civilization might be the end of us — but he was wrong about one thing: it is too late to avoid contact with ultra-intelligent extraterrestrial aliens.

They are here, now, and living with you, perhaps within you, in your home.

And their actions are utterly invisible.

Worse still, every human thought, every human response to this invisible terror is already known and is shared across an intergalactic telepathic mind-to-mind based Internet.

The above may sound like a science fiction tale, however the reality may be worse than our most feared imaginings.

To enter into this “Twilight Zone” of darkness we simply accept that the brief history of human scientific and technological evolution points to an ever-greater penetration of the human mind — and the probability, given the unfathomable vastness of eternity currently predicted by our best theories of the universe and beyond, of intelligent minds beyond our own.

Our deepest, inner thoughts and experiences are going to be turned inside out upon the world.

We enter this virtual reality with an understanding that an encounter with alien intelligence beyond our own is something we may not even recognize, if and when it happens.

And according to sources, some who have held high positions within the U.S. government, close encounters have already taken place.

It is this unseen, largely unheard and secret presence that haunts us like a secret society from the great beyond. Probing our actions — even before they are taken — the vast and disturbingly alien mind behind this unstoppable terror of invisible things surrounds us, watching and waiting, like an invisible guardian in a cosmic conspiracy written eons before our time.

The cover story for contact with this deeply disturbing intelligence was written in Hollywood: extraterrestrial biological entities arrived on Earth in flying saucers and maybe they even crashed a disk or two, which were later recovered by the government.

It is this wrap-over story that has been spread by a handful of former CIA-types including the recent revelation by Chase Brandon. According to Brandon, bodies and wreckage (presumably of an extraterrestrial alien origin) were indeed recovered in Roswell, New Mexico. Others have hinted of some deeply buried truth underlying the saucer tales, based upon hearsay from their more senior colleagues in intelligence. And this, so we are told, goes all the way to the top, coming from at least a handful of former CIA Directors.

But is there really any truth in the tales? At a minimum, we should begin our exploration of the unstoppable terror of invisible things with a brief examination of down-to-earth technologies from human sources. We will, for the time being, ignore that other Hollywood-inspired meme claiming the most advanced human technologies of the 21st century owe their existence to reverse engineered extraterrestrial technology.

There are other stories of possible relevance, tales of invisible things that sometimes show their face  in brief and mysterious ways. They sometimes seem to speak to select groups of human beings, in particular scientific types, using a form of direct mind-to-mind communication.

Mental radio has been an essential element of the pop culture for decades, and once again appears to be just another meme invented in the fantasy of a Hollywood writer’s imagination. The situation is further complicated by the countless number of persons who have self-experimented on the core physical structure of the human mind — the brain — by ingesting a wide variety of chemical substances known to create hallucinatory effects.

Invisible things do not always remain visible: there are other stories and sometimes grainy and poorly photographed images of manifestations of unusual phenomena popping in and out of our consensus reality. Other highly questionable reports include observations of ordinary material objects moving under the force of an unseen source. Several persons I know have related to me stories of so-called psychokinetic motion, including one person who told me of a misadventure involving knives that were picked up off of a table and flung with extreme force into the wall. In this particular story, it was reported that the environment changed mysteriously prior to the psychokinetic event, and even space and time seemed distorted in some inexplicable manner.

Psychokinesis was once a concern for American intelligence agencies and their political handlers in Congress (and this is confirmed within the declassified government record). Once upon a time they even feared psychokinetic hacking of America’s missile arsenal launch codes.

Invisibility is no longer bound to the imaginative world of sorcerer Harry Potter. As physicists look deeper into the nature of quantum reality they are gradually realizing new and clever ways around what was once assumed to be insurmountable obstacles. The late Arthur C. Clarke, author of “2001: A Space Odyssey” is often referenced for having said any sufficiently advanced technology appears (on the surface to those who do not understand it) to be magic.

Cracking through the barriers of human ignorance and human fantasy does not come easily. But if we are indeed facing an unstoppable terror of invisible things — real, physical forces under intelligent guidance — then we need to prepare a response.

We are challenged in this effort by the anthropocentric nature of the human mind: Is is really possible to envision truly alien sources and methods? Or are we confined to describing the extraterrestrial alien droning of America?

Bekkum makes many valid points about possible alien interference with we human beings on Earth; the most important point is the immaterial way the interference would take place. No flying saucers, triangles or spheres need apply.

Remote control of human beings, i.e., possession, ( or avatars ) via of “mental telepathy” for lack of a better term, would be preferable to outright invasion and destroying turf. Especially if proxy colonization or species manipulation is part and parcel of the alien’s overall strategies.

Unstoppable terror of invisible things

The Eerie Silence and Machine Intelligences

From The Daily Galaxy:

Conscious-machine_cp3hb_2263

The species that you and all other living human beings on this planet belong to is Homo sapiens. During a time of dramatic climate change 200,000 years ago,Homo sapiens (modern humans) evolved in Africa. Is the human species entering another evolutionary inflection point?

Paul Davies, a British-born theoretical physicist, cosmologist, astrobiologist and Director of the Beyond Center for Fundamental Concepts in Science and Co-Director of the Cosmology Initiative at Arizona State University, says in his new book The Eerie Silence that any aliens exploring the universe will be AI-empowered machines. Not only are machines better able to endure extended exposure to the conditions of space, but they have the potential to develop intelligence far beyond the capacity of the human brain.”I think it very likely – in fact inevitable – that biological intelligence is only a transitory phenomenon, a fleeting phase in the evolution of the universe,” Davies writes. “If we ever encounter extraterrestrial intelligence, I believe it is overwhelmingly likely to be post-biological in nature.”

Before the year 2020, scientists are expected to launch intelligent space robots that will venture out to explore the universe for us.
“Robotic exploration probably will always be the trail blazer for human exploration of far space,” says Wolfgang Fink, physicist and researcher at Caltech. “We haven’t yet landed a human being on Mars but we have a robot there now. In that sense, it’s much easier to send a robotic explorer. When you can take the human out of the loop, that is becoming very exciting.”
As the growing global population continues to increase the burden on the Earth’s natural resources, senior curator at the Smithsonian National Air and Space Museum, Roger Launius, thinks that we’ll have to alter human biology to prepare to colonize space.
In the September issue of Endeavour, Launius takes a look at the historical debate surrounding human colonization of the solar system. Experiments have shown that certain life forms can survive in space. Recently, British scientists found that bacteria living on rocks taken from Britain’s Beer village were able to survive 553 days in space, on the exterior of the International Space Station (ISS). The microbes returned to Earth alive, proving they could withstand the harsh environment.
Humans, on the other hand, are unable to survive beyond about a minute and a half in space without significant technological assistance. Other than some quick trips to the moon and the ISS, astronauts haven’t spent too much time too far away from Earth. Scientists don’t know enough yet about the dangers of long-distance space travel on human biological systems. A one-way trip to Mars, for example, would take approximately six months. That means astronauts will be in deep space for more than a year with potentially life-threatening consequences.
Launius, who calls himself a cyborg for using medical equipment to enhance his own life, says the difficult question is knowing where to draw the line in transforming human biological systems to adapt to space. Credit: NASA/Brittany Green
“If it’s about exploration, we’re doing that very effectively with robots,” Launius said. “If it’s about humans going somewhere, then I think the only purpose for it is to get off this planet and become a multi-planetary species.”
Stephen Hawking agrees: “I believe that the long-term future of the human race must be in space,” Hawking told the Big Think website in August. “It will be difficult enough to avoid disaster on planet Earth in the next hundred years, let alone the next thousand, or million. The human race shouldn’t have all its eggs in one basket, or on one planet.”
If humans are to colonize other planets, Launius said it could well require the “next state of human evolution” to create a separate human presence where families will live and die on that planet. In other words, it wouldn’t really be Homo sapien sapiens that would be living in the colonies, it could be cyborgs—a living organism with a mixture of organic and electromechanical parts—or in simpler terms, part human, part machine.
“There are cyborgs walking about us,” Launius said. “There are individuals who have been technologically enhanced with things such as pacemakers and cochlea ear implants that allow those people to have fuller lives. I would not be alive without technological advances.”
The possibility of using cyborgs for space travel has been the subject of research for at least half a century. A seminal  article published in 1960 by Manfred Clynes and Nathan Kline titled “Cyborgs and Space” changed the debate, saying that there was a better alternative to recreating the Earth’s environment in space, the predominant thinking during that time. The two scientists compared that approach to “a fish taking a small quantity of water along with him to live on land.” They felt that humans should be willing to partially adapt to the environment to which they would be traveling.
“Altering man’s bodily functions to meet the requirements of extraterrestrial environments would be more logical than providing an earthly environment for him in space,” Clynes and Kline wrote.
“It does raise profound ethical, moral and perhaps even religious questions that haven’t been seriously addressed,” Launius said. “We have a ways to go before that happens.”
Some experts such as medical ethicist Grant Gillett believe that the danger is that we might end up producing a psychopath because we don’t quite understand the nature of cyborgs.
NASA, writes Lauris, still isn’t focusing much research on how to improve human biological systems for space exploration. Instead, its Human Research Program is focused on risk reduction: risks of fatigue, inadequate nutrition, health problems and radiation. While financial and ethical concerns may have held back cyborg research, Launius believes that society may have to engage in the cyborg debate again when space programs get closer to launching long-term deep space exploration missions.
“If our objective is to become space-faring people, it’s probably going to force you to reconsider how to reengineer humans,’ Launius said.
When one mentions merging humans with machines in the future, it is usually in the context of the Technological Singularity, not long range space exploration ( although as little as ten years ago, this was a serious proposal considered by NASA ).
Many have thought of the Eerie Silence over the decades, including futurists as George Dvorsky and John Smart, who propose that once man and machines merge, a super-intelligence will emerge and our civilization will disappear from the visible Universe.
Thus, another possible explanation for the Eerie Silence.

Another Asteroid Mining Company Start-Up

From Centauri Dreams:

Deep Space Industries is announcing today that it will be engaged in asteroid prospecting through a fleet of small ‘Firefly’ spacecraft based on cubesat technologies, cutting the costs still further by launching in combination with communications satellites. The idea is to explore the small asteroids that come close to Earth, which exist in large numbers indeed. JPL analysts have concluded that as many as 100,000 Near Earth Objects larger than the Tunguska impactor (some 30 meters wide) are to be found, with roughly 7000 identified so far. So there’s no shortage of targets (see Greg Matloff’s Deflecting Asteroids in IEEE Spectrum for more on this.

‘Smaller, cheaper, faster’ is a one-time NASA mantra that DSI is now resurrecting through its Firefly spacecraft, each of which masses about 25 kilograms and takes advantages of advances in computing and miniaturization. In its initial announcement, company chairman Rick Tumlinson talked about a production line of Fireflies ready for action whenever an NEO came near the Earth. The first launches are slated to begin in 2015. Sample-return missions that are estimated to take between two and four years to complete are to commence the following year, with 25 to 70 kilograms of asteroid material becoming available for study. Absent a fiery plunge through the atmosphere, such samples will have their primordial composition and structure intact.

The Deep Space Industries announcement is to be streamed live later today. It will reflect the company’s ambitious game plan, one that relies on public involvement and corporate sponsorship to move the ball forward. David Gump is CEO of the new venture:

“The public will participate in FireFly and DragonFly missions via live feeds from Mission Control, online courses in asteroid mining sponsored by corporate marketers, and other innovative ways to open the doors wide. The Google Lunar X Prize, Unilever, and Red Bull each are spending tens of millions of dollars on space sponsorships, so the opportunity to sponsor a FireFly expedition into deep space will be enticing.”

The vision of exploiting space resources to forge a permanent presence there will not be unfamiliar to Centauri Dreams readers. Tumlinson sums up the agenda:

“We will only be visitors in space until we learn how to live off the land there. This is the Deep Space mission – to find, harvest and process the resources of space to help save our civilization and support the expansion of humanity beyond the Earth – and doing so in a step by step manner that leverages off our space legacy to create an amazing and hopeful future for humanity. We are squarely focused on giving new generations the opportunity to change not only this world, but all the worlds of tomorrow.  Sounds like fun, doesn’t it?”

So we have asteroid sample return as part of the mix, but the larger strategy calls for the use of asteroid-derived products to power up space industries. The company talks about using asteroid-derived propellants to supply eventual manned missions to Mars and elsewhere, with Gump likening nearby asteroid resources to the Iron Range of Minnesota, which supplied Detroit’s car industry in the 20th Century. DSI foresees supplying propellant to communication satellites to extend their working lifetime, estimating that each extra month is worth $5 million to $8 million per satellite. The vision extends to harvesting building materials for subsequent technologies like space-based power stations. Like I said, the key word is ‘ambitious.’

“Mining asteroids for rare metals alone isn’t economical, but makes sense if you already are processing them for volatiles and bulk metals for in-space uses,” said Mark Sonter, a member of the DSI Board of Directors. “Turning asteroids into propellant and building materials damages no ecospheres since they are lifeless rocks left over from the formation of the solar system.  Several hundred thousand that cross near Earth are available.”

In the near-term category, the company has a technology it’s calling MicroGravity Foundry that is designed to transform raw asteroid materials into metal parts for space missions. The 3D printer uses lasers to draw patterns in a nickel-charged gas medium, building up parts from the precision placement of nickel deposits. Because it does not require a gravitational field to work, the MicroGravity Foundry could be a tool used by deep space astronauts to create new parts aboard their spacecraft by printing replacements.

The team behind Deep Space Industries has experience in commercial space activities. Tumlinson, a well-known space advocate, was a founding trustee of the X Prize and founder of Orbital Outfitters, a commercial spacesuit company. Gump has done space-related TV work, producing a commercial shot on the International Space Station. He’s also a co-founder of Transformational Space Corporation. Geoffrey Notkin is the star of ‘Meteorite Men,’ a TV series about hunting meteorites. The question will be how successful DSI proves to be in leveraging that background to attract both customers and corporate sponsors.

With such bold objectives, I can only wish Deep Space Industries well. The idea of exploiting inexpensive CubeSat technology and combining it with continuing progress in miniaturizing digital tools is exciting, but the crucial validation will be in those early Firefly missions and the data they return. If DSI can proceed with the heavier sample return missions it now envisions, the competitive world of asteroid prospecting (think Planetary Resources) will have taken another step forward. Can a ‘land rush’ for asteroid resources spark the public’s interest, with all the ramifications that would hold for the future of commercial space? Could it be the beginning of the system-wide infrastructure we’ll have to build before we think of going interstellar?

All of this asteroid mining activity sounds exciting and I can hardly wait for DSI and Planetary Resources to begin their plans. Both are using untried and new technology to develop these new industries and can be extended to such environments as the Moon and Mars.

Mankind will eventually follow. And these new technologies will let us expand into this Universe.

Or the Multiverse.

NASA’s Green Aviation Research and a possible reason for Alien Invasion

From Phys.Org:

NASA has selected eight large-scale integrated technology demonstrations to advance aircraft concepts and technologies that will reduce the impact of aviation on the environment over the next 30 years, research efforts that promise future travelers will fly in quieter, greener and more fuel-efficient airliners.

The demonstrations, which are part of by NASA’s Environmentally Responsible Aviation (ERA) Project, will focus on five areas—aircraft drag reduction through innovative flow control concepts, weight reduction from advanced composite materials, fuel and noise reduction from advanced engines, emissions reductions from improved engine combustors, and fuel consumption and community noise reduction through innovative airframe and engine integration designs. The selected demonstrations are: Active Flow Control Enhanced Vertical Tail Flight Experiment: Tests of technology that can manipulate, on demand, the air that flows over a full-scale commercial aircraft tail. Damage Arresting Composite Demonstration: Assessment of a low-weight, damage-tolerant, stitched composite structural concept, resulting in a 25 percent reduction in weight over state-of-the-art aircraft composite applications. Adaptive Compliant Trailing Edge Flight Experiment: Demonstration of a non-rigid wing flap to establish its airworthiness in the flight environment.Highly Loaded Front Block Compressor Demonstration: Tests to show Ultra High Bypass (UHB) or advanced turbofan efficiency improvements of a two-stage, transonic high-pressure engine compressor.2nd Generation UHB Ratio Propulsor Integration: Continued development of a geared turbofan engine to help reduce fuel consumption and noise.Low Nitrogen Oxide Fuel Flexible Engine Combustor Integration: Demonstration of a full ring-shaped engine combustor that produces very low emissions. Flap and Landing Gear Noise Reduction Flight Experiment: Analysis, wind tunnel and flight tests to design quieter flaps and landing gear without performance or weight penalties.UHB Engine Integration for a Hybrid Wing Body: Verification of power plant and airframe integration concepts that will allow fuel consumption reductions in excess of 50 percent while reducing noise on the ground.”With these demonstrations we will take what we’ve learned and move from the laboratory to more flight and ground technology tests,” said Fay Collier, ERA project manager based at NASA’s Langley Research Center in Hampton, Va. “We have made a lot of progress in our research toward very quiet aircraft with low carbon footprints. But the real challenge is to integrate ideas and pieces together to make an even larger improvement. Our next steps will help us work towards that goal.”

I find this research fascinating because it relates to a National Geographic Special I saw yesterday about an alien invasion ( and yes, according to the people being interviewed, the U.S. Government does have a plan for such a thing ) and the reason the aliens ( which were robots no less ) invaded was because the Earth is full of chlorophyll and other biology that could be harvested for biofuel.

Now I seriously don’t believe total machine intelligence would travel tens or hundreds of light-years and for hundreds of years to harvest biofuel for their starship which would surely be powered by anti-matter or vacuum energy. I hardly believe that these sources are fueled by biofuels.

But if the aliens are cybernetic organisms, such as the “Borg” of Star Trek fame, then I could assume their interest in our world for biofuel is believable and the U.S. Government’s plan for fighting an invasion is realistic.

Maybe the government really does know something we don’t? I sure hope we don’t find out the hard way.

Robot Rovers To Explore Asteroids and Moons

From kurzweilai.net:

Stanford researchers in collaboration with NASA JPL and MIT have designed a robotic platform that involves a mother spacecraft deploying one or several spiked, roughly spherical rovers to the Martian moon Phobos.

Measuring about half a meter wide, each rover would hop, tumble and bound across the cratered, lopsided moon, relaying information about its origins, as well as its soil and other surface materials.

Developed by Marco Pavone, an assistant professor in Stanford’s Department of Aeronautics and Astronautics, the Phobos Surveyor, a coffee-table-sized vehicle flanked by two umbrella-shaped solar panels, would orbit around Phobos throughout the mission. The researchers have already constructed a prototype.

The Surveyor would release only one hedgehog at a time. Together, the mothership and hedgehogs would work together to determine the hedgehog’s position and orientation. Using this information, they would map a trajectory, which the mother craft would then command the hedgehog to travel.

In turn, the spiky explorers would relay scientific measurements back to the Phobos Surveyor, which would forward the data to researchers on Earth. Based on their analysis of the data, the scientists would direct the mothership to the next hedgehog deployment site.

An entire mission would last two to three years. Just flying to Phobos would take the Surveyor about two years. Then the initial reconnaissance phase, during which the Surveyor would map the terrain, would last a few months. The mothership would release each of the five or six hedgehogs several days apart, allowing scientists enough time to decide where to release the next hedgehog.

For many decisions, Pavone’s system renders human control unnecessary. “It’s the next level of autonomy in space,” he said.

Moon clues

The synergy between the Phobos Surveyor and the hedgehogs would also be reflected in their sharing of scientific roles. The Surveyor would take large-scale measurements, while the hedgehogs would gather more detailed data. For example, the Surveyor might use a gamma ray or neutron detector to measure the concentration of various chemical elements and compounds on the surface, while the hedgehogs might use microscopes to measure the fine crevices and fissures lining the terrain.

Although scientists could use the platform to explore any of the solar system’s smaller members, including comets and asteroids, Pavone has designed it with the Martian moon Phobos in mind.

An analysis of Phobos’ soil composition could uncover clues about the moon’s origin. Scientists have yet to agree on whether Phobos is an asteroid captured by the gravity of Mars or a piece of Mars that an asteroid impact flung into orbit. This could have deep implications for our current understanding of the origin and evolution of the solar system, Pavone said.

To confirm Phobos’ origins, Pavone’s group plans to deploy most of the hybrids near Stickney Crater. Besides providing a gravity “sweet spot” where the mother craft can stably hover between Mars and Phobos, the crater also exposes the moon’s inner layers.

A human mission to Mars presents hefty challenges, mainly associated with the planet’s high gravity, which heightens the risk of crashing during takeoffs and landings. The large amounts of fuel needed to overcome Mars’ strong pull during takeoffs could also make missions prohibitively expensive.

But Phobos’ gravity is a thousand times weaker than on Mars. If Phobos did indeed originate from the red planet, scientists could study Mars without the dangers and costs associated with its high gravity simply by sending astronauts to Phobos. They could study the moon itself or use it as a base station to operate a robot located on Mars.  The moon could also serve as a site to test technologies for potential use in a human mission to the planet.

“It’s a piece of technology that’s needed before any more expensive type of exploration is considered,” Pavone said of the spacecraft-rover hybrid. “Before sampling we need to know where to land. We need to deploy rovers to acquire info about the surface.”

These probes could  be precursors to a sample return mission. A promising area to dig determined beforehand would cut down on cost and wear and tear.

But these rovers could be used on their own for private industry, such as Google Maps in order to give ( and sell ) accurate virtual reality tours to Millenials who wish to sit in their livingrooms and explore Mars safely.

A true pre-Singularity technology.

Acrobatic space rovers to explore moons and asteroids

Slow Galactic Colonization, Zoo Hypothesis and the Fermi Paradox

I couldn’t resist posting this today after reading it at Centauri Dreams. It’s extremely mainstream, by which the papers Paul Gilster discusses uses geological travel times for interstellar travel and the effects on the Fermi Paradox.

But he talks about the “zoo” hypothesis for our supposed lack of contact with ETIs ( no discussion of UFOs what-so-ever of course ) and I find that fascinating:

[...]

Many explanations for the Fermi paradox exist, but Hair and Hedman want to look at the possibility that starflight is so long and difficult that it takes vast amounts of time (measured in geologic epochs) to colonize on the galactic scale. Given that scenario, large voids within the colonized regions may still persist and remain uninhabited. If the Earth were located inside one of these voids we would not be aware of the extraterrestrial expansion. A second possibility is that starflight is so hard to achieve that other civilizations have simply not had time to reach us despite having, by some calculations, as much as 5 billion years to have done so (the latter figure comes from Charles Lineweaver, and I’ll have more to say about it in a moment).

Image: A detailed view of part of the disc of the spiral galaxy NGC 4565. Have technological civilizations had time enough to spread through an entire galaxy, and if so, would they be detectable? Credit: ESA/NASA.

The authors work with an algorithm that allows modeling of the expansion from the original star, running through iterations that allow emigration patterns to be analyzed in light of these prospects. It turns out that in 250 iterations, covering 250,000 years, a civilization most likely to emigrate will travel about 500 light years, for a rate of expansion that is approximately one-fourth of the maximum travel speed of one percent of the speed of light, the conservative figure chosen for this investigation. A civilization would spread through the galaxy in less than 50 million years.

These are striking numbers. Given five billion years to work with, the first civilization to develop starfaring capabilities could have colonized the Milky Way not one but 100 times. The idea that it takes billions of years to accomplish a galaxy-wide expansion fails the test of this modeling. Moreover, the idea of voids inside colonized space fails to explain the Fermi paradox as well:

…while interior voids exist at lower values of c initially, most large interior voids become colonized after long periods regardless of the cardinal value chosen, leaving behind only relatively small voids. In an examination of several 250 Kyr models with a wide range of parameters, the largest interior void encountered was roughly 30 light years in diameter. Since humans have been broadcasting radio since the early 20th century and actively listening to radio signals from space since 1960 (Time 1960), it is highly unlikely that the Earth is located in a void large enough to remain undiscovered to the present day. It follows that the second explanation of Fermi’s Paradox (Landis 1998) is not supported by the model presented.

There are mitigating factors that can slow down what the authors call the ‘explosively exponential nature’ of expansion, in which a parent colony produces daughter colonies and the daughters continue to do the same ad infinitum. The paper’s model suggests that intense competition for new worlds can spring up in the expanding wavefront of colonization. At the same time, moving into interior voids to fill them with colonies slows the outward expansion. But even models set up to reduce competition between colonies present the same result: Fermi’s lunchtime calculations seem to be valid, and the fact that we do not see evidence of other civilizations suggests that this kind of galactic expansion has not yet taken place.

Temporal Dispersion into the Galaxy

I can’t discuss Hair and Hedman’s work without reference to Hair’s earlier paper on the expansion of extraterrestrial civilizations over time. Tom had sent me this one in 2011 and I worked it into the Centauri Dreams queue before getting sidetracked by preparations for the 100 Year Starship symposium in Orlando. If I had been on the ball, I would have run an analysis of Tom’s paper at the time, but the delay gives me the opportunity to consider the two papers together, which turns out to work because they are a natural fit.

For you can see that Hair’s spatial analysis goes hand in glove with the question of why an extraterrestrial intelligence might avoid making its presence known. Given that models of expansion point to a galaxy that can be colonized many times over before humans ever emerged on our planet, let’s take up a classic answer to the Fermi paradox, that the ‘zoo hypothesis’ is in effect, a policy of non-interference in local affairs for whatever reason. Initially compelling, the idea seems to break down under close examination, given that it only takes one civilization to act contrary to it.

But there is one plausible scenario that allows the zoo hypothesis to work: The influence of a particularly distinguished civilization. Call it the first civilization. What sort of temporal head start would this first civilization have over later arrivals?

Hair uses Monte Carlo simulations, drawing on the work of Charles Lineweaver and the latter’s estimate that planets began forming approximately 9.3 billion years ago. Using Earth as a model and assuming that life emerged here about 600 million years after formation, we get an estimate of 8.7 billion years ago for the appearance of the first life in the Milky Way. Factoring in how long it took for complex land-dwelling organisms to evolve (3.7 billion years), Lineweaver concludes that the conditions necessary to support intelligent life in the universe could have been present for at least 5.0 billion years. At some point in that 5 billion years, if other intelligent species exist, the first civilization arose. Hair’s modeling goes to work on how long this civilization would have had to itself before other intelligence emerged. The question thus has Fermi implications:

…even if this first grand civilization is long gone . . . could their initial legacy live on in the form of a passed down tradition? Beyond this, it does not even have to be the first civilization, but simply the first to spread its doctrine and control over a large volume of the galaxy. If just one civilization gained this hegemony in the distant past, it could form an unbroken chain of taboo against rapacious colonization in favour of non-interference in those civilizations that follow. The uniformity of motive concept previously mentioned would become moot in such a situation.

Thus the Zoo Hypothesis begins to look a bit more plausible if we have each subsequent civilization emerging into a galaxy monitored by a vastly more ancient predecessor who has established the basic rules for interaction between intelligent species. The details of Hair’s modeling are found in the paper, but the conclusions are startling, at least to me:

The time between the emergence of the first civilization within the Milky Way and all subsequent civilizations could be enormous. The Monte Carlo data show that even using a crowded galaxy scenario the first few inter-arrival times are similar in length to geologic epochs on Earth. Just what could a civilization do with a ten million, one hundred million, or half billion year head start (Kardashev 1964)? If, for example, civilizations uniformly arise within the Galactic Habitable Zone, then on these timescales the first civilization would be able to reach the solar system of the second civilization long before it evolved even travelling at a very modest fraction of light speed (Bracewell 1974, 1982; Freitas 1980). What impact would the arrival of the first civilization have on the future evolution of the second civilization? Would the second civilization even be allowed to evolve? Attempting to answer these questions leads to one of two basic conclusions, the first is that we are alone in the Galaxy and thus no one has passed this way, and the second is that we are not alone in the Galaxy and someone has passed this way and then deliberately left us alone.

The zoo hypothesis indeed. A galactic model of non-interference is a tough sell because of the assumed diversity between cultures emerging on a vast array of worlds over time. But Hair’s ‘modified zoo hypothesis’ has great appeal. It assumes that the oldest civilization in the galaxy has a 100 million year head start, allowing it to become hugely influential in monitoring or perhaps controlling emerging civilizations. We would thus be talking about the possibility of evolving similar cultural standards with regard to contact as civilizations follow the lead of this assumed first intelligence when expanding into the galaxy. It’s an answer to Fermi that holds out hope we are not alone, and I’ll count that as still another encouraging thought on the day the world didn’t end.

I have a problem with this simply because of the economics involved; what is the motivation for ETIs to expand into the Universe to begin with?

Like, are they like humans in the sense that we go because “it’s there?”

Or are there more practical impulses involved like “can we make money” on these endeavors?

A commentor to this particular post wrote that before we colonize ( if we ever do ) the Moon, Mars and other planets in this Solar System ( and perhaps the closer stars ) that it’ll be cheaper to shoot small probes with micro cameras to these places ( NASA is already proposing sending tele-operated probes to the Lunar surface instead of astronauts ) and sell virtual reality tours. Expanded versions of Google Earth and Google Mars!

In other words, it’s cheaper to build Universes that have Star Trek and upload your mind into it than actually building such things as star-ships!

Could this be an answer to the Fermi Paradox?
