This is an interview with the true inventor of the InnerTubes.
Not Al Gore.
When some future Mars colonist is able to open his browser and watch a cat in a shark suit chasing a duck while riding a roomba, they will have Vint Cerf to thank.
In his role as Google’s chief internet evangelist, Cerf has spent much of his time thinking about the future of the computer networks that connect us all. And he should know. Along with Bob Kahn, he was responsible for developing the internet protocol suite, commonly known as TCP/IP, that underlies the workings of the net. Not content with just being a founding father of the internet on this planet, Cerf has spent years taking the world wide web out of this world.
Working with NASA and JPL, Cerf has helped develop a new set of protocols that can stand up to the unique environment of space, where orbital mechanics and the speed of light make traditional networking extremely difficult. Though this space-based network is still in its early stages and has few nodes, he said that we are now at “the front end of what could be an evolving and expanding interplanetary backbone.”Father of the Internet Vint Cerf is responsible for helping develop the TCP/IP protocols that underly the web.

Wired talked to Cerf about the interplanetary internet’s role in space exploration, the frustrations of network management on the final frontier, and the future headline he never wants to see.
Wired: Though it’s been around a while, the concept of an interplanetary internet is probably new to a lot of people. How exactly do you build a space network?
Vint Cerf: Right, it’s actually not new at all – this project started in 1998. And it got started because 1997 was very nearly the 25th anniversary of the design of the internet. Bob Kahn and I did that work in 1973. So back in 1997, I asked myself what should I be doing that will be needed 25 years from then. And, after consultation with colleagues at the Jet Propulsion Laboratory, we concluded that we needed much richer networking than was then available to NASA and other space faring agencies.
Up until that time and generally speaking, up until now, the entire communications capabilities for space exploration had been point-to-point radio links. So we began looking at the possibilities of TCIP/IP as a protocol for interplanetary communication. We figure it worked on Earth and it ought to work on Mars. The real question was, “Would it work between the planets?” And the answer turned out to be, “No.”
The reason for this is two-fold: First of all, the speed of light is slow relative to distances in the solar system. A one-way radio signal from Earth to Mars takes between three and half and 20 minutes. So round trip time is of course double that. And then there’s the other problem: planetary rotation. If you’re communicating with something on the surface of the planet, it goes out of communication as the planet rotates. It breaks the available communications and you have to wait until the planet rotates back around again. So what we have is variable delay and disruption, and TCP does not do terribly well in those kinds of situations.
One of the things that the TCP/IP protocols assume is that there isn’t enough memory in each of the routers to hold anything. So if a packet shows up and it’s destined for a place for which you have an available path, but there isn’t enough room, then typically the packet is discarded.
We developed a new suite of protocols that we called the Bundle protocols, which are kind of like internet packets in the sense that they’re chunks of information. They can be quite big and they basically get sent like bundles of information. We do what’s called storing forward, which is the way all packet switching works. It’s just in this case the interplanetary protocol has the capacity to store quite a bit, and usually for quite a long time before we can get rid of it based on connectivity to the next hop.
Wired: What are the challenges with working and making a communications network in space as opposed to a ground-based internet?
Cerf: Among the hard things, first of all, is that we couldn’t use the domain name system in its current form. I can give you a quick illustration why that’s the case: Imagine for a moment you’re on Mars, and somebody is trying to open up an HTTP web connection to Earth. They’ve given you a URL that contains a domain name in it, but before you can open up a TCP connection you need to have an IP address.
So you will have to do a domain name lookup, which can translate the domain name you’re trying to lookup into an IP address. Now remember you’re on Mars and the domain name you’re trying to look up is on Earth. So you send out a DNS lookup. But it may take anywhere from 40 minutes to an unknown amount of time — depending on what kind of packet loss you have, whether there’s a period of disruption based on planetary rotation, all that kind of stuff — before you get an answer back. And then it may be the wrong answer, because by the time it gets back maybe the node has moved and now it has a different IP address. And from there it just gets worse and worse. If you’re sitting around Jupiter, and trying to do a lookup, many hours go by and then it’s just impossible.
So we had to break it into a two-phase lookup and use what’s called delayed binding. First you figure out which planet you’re going to, then you route the traffic to that planet, and only then you do a local lookup, possibly using the domain name.
The other thing is when you are trying to manage a network with this physical scope and all the uncertainty delays, the things we typically do for network management don’t work very well. There’s a protocol called SNMP, the simple network management protocol, and it is based on the idea that you can send a packet out and get an answer back in a few milliseconds, or a few hundreds of milliseconds. If you’re familiar with the word ping, you’ll know what I mean, because you ping something and expect to get an answer back fairly quickly. If you don’t get it back in a minute or two, you begin to conclude that there is something wrong and the thing isn’t available. But in space, it takes a long time for the signal to even get to the destination let alone get an answer back. So network management turns out to be a lot harder in this environment.
Then the other thing we had to worry about was security. The reason for that should be obvious — one of the things we wanted to avoid was the possibility of a headline that says: “15-Year-Old Takes Over Mars Net.” Against that possibility we put quite a bit of security into the system, including strong authentication, three way handshakes, cryptographic keys, and things of that sort in order to reduce the likelihood that someone would abuse access to the space network.
Wired: Because it has to communicate across such vast distances, it seems like the interplanetary internet must be huge.
Cerf: Well, in purely physical terms — that is, in terms of distance — it’s a pretty large network. But the number of nodes is pretty modest. At the moment, the elements participating in it are devices in planet Earth, including the Deep Space Network, which is operated at JPL. That consists of three 70-meter dishes plus a smattering of 35-meter dishes that can reach out into the solar system with point-to-point radio links. Those are part of the TDRSS [tee-driss] system, which is used for a lot of near-Earth communications by NASA. The ISS also has several nodes on board capable of using this particular set of protocols.
Two orbiters around Mars are running the prototype versions of this software, and virtually all the information that’s coming back from Mars is coming back via these store-forward relays. The Spirit and Opportunity rovers on the planet and the Curiosity rover are using these protocols. And then there’s the Phoenix lander, which descended to the north pole of Mars in 2008. It also was using these protocols until the Martian winter shut it down.
And finally, there’s a spacecraft in orbit around the sun, which is actually quite far away, called EPOXI [the spacecraft was 32 million kilometers from Earth when it tested the interplanetary protocols]. It has been used to rendezvous with two comets in the last decade to determine their mineral makeup.
But what we hope will happen over time — assuming these protocols are adopted by the Consultative Committee on Space Data Systems, which standardizes space communication protocols — then every spacefaring nation launching either robotic or manned missions has the option of using these protocols. And that means that all the spacecraft that have been outfitted with those protocols could be used during the primary mission, and could then be repurposed to become relays in a stored forward network. I fully expect to see these protocols used for both manned and robotic exploration in the future.
Wired: What are the next steps to expand this?
Cerf: We want to complete the standardization with the rest of the spacefaring community. Also, not all pieces are fully validated yet, including our strong authentication system. Then second, we need to know how well we can do flow control in this very, very peculiar and potentially disrupted environment.
Third, we need to verify that we can do serious real-time things including chat, video and voice. We will need to learn how to go from what appears to be an interactive real-time chat, like one over the phone, to probably an email-like exchange, where you might have voice and video attached but it’s not immediately interactive.
Delivering the bundle is very much like delivering a piece of email. If there’s a problem with email it usually gets retransmitted, and after a while you time out. The bundle protocol has similar characteristics, so you anticipate that you have variable delay that could be very long. Sometimes if you’ve tried many times and don’t get a response, you have to assume the destination is not available.
Wired: We often talk about how the things we invent for space are being used here on Earth. Are there things about the interplanetary internet that could potentially be used on the ground?
Cerf: Absolutely. The Defense Advanced Research Projects Agency (DARPA) funded tests with the U.S. Marine Corps on tactical military communication using these highly resilient and disruption-tolerant protocols. We had successful tests that showed in a typical hostile communication environment that we were able to put three to five times more data through this disrupted system than we could with traditional TCP/IP.
Part of the reason is that we assume we can store traffic in the network. When there’s high activity, we don’t have to retransmit from end to end, we can just retransmit from one of the intermediate points in the system. This use of memory in the network turns out to be quite effective. And of course we can afford to do that because memory has gotten so inexpensive.
The European Commission has also sponsored a really interesting project using the DTM protocols in northern Sweden. In an area called Lapland, there’s a group called the Saami reindeer herders. They’ve been herding reindeer for 8,000 years up there. And the European Commission sponsored a research project managed by the Lulea University of Technology in northern Sweden to put these protocols on board all-terrain vehicles in laptops. This way, you could run a Wi-Fi service in villages in Northern Sweden and drop messages off and pick them up according to the protocols. As you move around, you were basically a data mule carrying information from one village to another.
Wired: There was also an experiment called Mocup that involved remote controlling a robot on Earth from the space station. These protocols were used, right?
Cerf: Yes, we used the DTN protocols for that. We were all really excited for that because, although the protocols were originally designed to deal with very long and uncertain delay, when there is high quality connectivity, we can use it for real-time communication. And that’s exactly what they did with the little German rover.
I think in general communication will benefit from this. Putting these protocols in mobile phones, for instance, would create a more powerful and resilient communications platform than what we typically have today
Wired: So if I have poor reception on my cell phone at my house, I could still call my parents?
Cerf: Well, actually what might happen is that you could store what you said and they would eventually get it. But it wouldn’t be real time. If the disruption lasts for an appreciable length of time, it would arrive later. But at least the information would eventually get there.
What about quantum entanglement?
There’s an experiment to be done in 2016 which an entangled signal is to be sent to a satellite launched by the Chinese, ( The Race to Bring Quantum Teleportation to Your World ).
Will that make the Interplanetary Internet obsolete before it literally gets off the ground?
Or will quantum entanglement enhance it?
(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.
BY EDITOR’S NEWS DESK STAFF
Sources are reporting that CIA superstar psychic spy Ingo Swann, known as the father of America’s secret remote viewing program, has died.
Swann’s story of recruitment by a covert black ops group in the 1970s was the inspiration for author Gary S. Bekkum’s book “To the Moon and Back, With Love.”
According to one of Swann’s psychic students, former U.S. government spy Paul Smith, “At the time of his death, on February 1, 2013, Ingo was well along in the process of creating a new book featuring his marvelous art work.”
Supported by the military and intelligence communities, Ingo worked through the program at SRI-International to not only explore the boundary conditions of remote viewing, the consciousness-based skill that he had discovered and developed, but he used it operationally to discover some of the secrets America’s erstwhile Cold War opponents were trying to hide.
Here is an excerpt from the book “To the Moon and Back, With Love” about Ingo Swann’s encounter with a mysterious black ops leader called Mr. Axelrod and otherworldly beings on the lunar surface.
Government consultant Ingo Swann’s tale of covert extraterrestrial activity on the moon takes on a new twist, now that the CIA STAR GATE documents support many of his claims.
3 August 2006
(STARpod.us) — This is the bizarre true tale of Ingo Swann’s psychic work for the U.S government, at various agencies including the CIA and the DIA (now substantiated by the CIA release of roughly two thirds of the existing STAR GATE documents) and his personal allegations of a mysterious black operation that first contacted him during the peak of CIA sponsored testing at the Stanford Research Institute.
If Ingo Swann is to be believed, and this coming from a man with top secret clearance that in his day briefed and trained officers from the U.S. Air Force, the Defense Intelligence Agency, INSCOM, and many others too numerous to mention, then there is some truth to the rumors of an otherworldly intelligence working behind the scenes here on Earth. Not only are they already here, according to Swann’s testimony from a rare out-of-print book, self-published in 1998, but they are building something on the far side of the moon.
And they are not friendly.
The truth is stranger than fiction, and this story is guaranteed to stretch the imagination right back into reality. For Ingo Swann, the turning point leading into the cloak and dagger world of deep black ops and weird requests for psychic surveillance of the moon and beyond began in early 1975. When Swann published his tale in 1998, most of the CIA and DIA classified documents from the secret STAR GATE program were still unavailable to the general public. As this story goes to press, in the summer of 2006, more than 80,000 pages of documents are close at hand here at STARstream Research, including the results of medical and psychological tests conducted on Mr. Swann as a result of his CIA sponsored testing while working with SRI: The Stanford Research Institute, in the 1970′s.
The CIA STAR GATE Program
In the early 1970′s concerns began to float about the various intelligence agencies over a psychic war gap with the Soviet Union. Unknown to the general public, the Soviets were busy exploring fringe science: application of the dark shadow of the paranormal world for espionage.
Swann’s abilities had been tracked for some time, but they really attracted the powers that be in Langley with the recording of an apparent perturbation of delicate test equipment by Swann’s mental perception. In addition to disturbing the output of this sensitive instrument, Swann was able to produce a rough description of the device, which he had never seen previously.
In a letter dated June 27, 1972, Dr. Hal Puthoff of SRI wrote, “At the suggestion of Russell Targ I am writing you about an observation in the laboratory involving one Ingo Swann, a New York artist … An interesting side light of the experiment was that Ingo was able to describe rather well what the interior of the device looked like, apparently with some form of direct observation.” Although redacted, it is likely that the recipient of this letter was at the CIA. Apparently sponsorship of Dr. Puthoff’s interest in Swann’s mental interaction with the test equipment followed quickly.
Among the STAR GATE files is a Stanford Research Institute (SRI) Technical Memorandum dated 22 February, 1973, prepared by Dr. Hal Puthoff and Russell Targ, Contract Number 1471(S)73 and tagged by CIA/ORD # 1416-73:
“A program in biofield measurements was initiated in July, 1972 with a preliminary experiment with Mr. [Ingo] Swann. In this work using a shielded magnetometer, Mr. Swann apparently demonstrated an ability to increase and decrease at will the magnetic field within a superconducting magnetic shield. This experiment made use of an existing facility and we have confidence that Mr. Swann had no prior knowledge of either the apparatus or of our intended experiment.”
An August, 1972 memo to the Chief of TSD/BAB at the CIA notes that “[name redacted] and somebody named [redacted] from [CIA] Life Sciences are planning a trip to the West Coast on 11 August, when they will meet Ingo Swann and have a chance to watch him flex his sphincter … Life Sciences is planning on forming a coordinating committee to work on ESP and the data that is coming in …”
When we contacted the unnamed former officer from CIA Life Sciences, he confirmed the authenticity of the document, but denied any knowledge of Swann’s tale.
An undated draft memorandum from Deputy Director for Operations William Colby, addressed to the “Director of Central Intelligence,” reveals the clandestine nature of CIA involvement in research using human subjects:
“Recently, two individuals, Mr. Uri Geller and Mr. Ingo Swann, appear to have demonstrated certain of these abilities [paraphysical effects] under controlled laboratory conditions. The abilities of these individuals (unwitting of Agency [CIA] sponsorship) are being submitted to a serious scientific investigation, part of which is being supported by the above mentioned project.”
An anonymous source, working in the alternative energy and transportation industry recently commented, “Actually, they became interested in Swann when he RV’ed [psychically remote viewed] some of their well-hidden deep underground vaults, and the contents thereof. This was when they approached SRI because they were finally truly scared about the reality of RV [psychic remote viewing] as a tool in the hands of the Soviets.”
Based upon the available records in STAR GATE, no one seems to have seriously considered that all of these manifestations of the impossible were strong indications of interference in human affairs by higher intelligence with more powerful technologies at their disposal. Or did they? Swann’s account in his book suggests that someone lurking in the shadows was paying very close attention; someone whose reach included the often super-secret work done at SRI.
Arthur C. Clarke once said and I’m paraphrasing here, “Advanced extraterrestrial technology would be indistinguishable from magic.”
Now, I’m not sure Ingo Swann actually made mind contact with ETIs on the far side of the Moon or not and it certainly isn’t outside the realm of possibility.
My question is, “Why would an advanced civilization interfere with us in any meaningful way and what is it’s purpose?”
Even if they were interdimensional in nature, the same questions apply.
In the end, Ingo Swann had great influence on the U.S. Government via the work he did with the CIA and in the end proved there are pathways through other dimensions in which communications and observations are performed.
Just ask DARPA.
When it comes to the Multiverse, several folks claim it’s all fantasy and let’s face it, the idea of several Universes just immeasurable millimeters away from our very noses reads like Alice in Wonderland or The Wizard of Oz.
But to Michael Hanlon, not only does the multiverse seem like the ultimate reality, it’s populated with any kind of reality that’s ever been theorized.
And then some.
Our understanding of the fundamental nature of reality is changing faster than ever before. Gigantic observatories such as the Hubble Space Telescope and the Very Large Telescope on the Paranal Mountain in Chile are probing the furthest reaches of the cosmos. Meanwhile, with their feet firmly on the ground, leviathan atom-smashers such as the Large Hadron Collider (LHC) under the Franco-Swiss border are busy untangling the riddles of the tiny quantum world.
Myriad discoveries are flowing from these magnificent machines. You may have seen Hubble’s extraordinary pictures. You will probably have heard of the ‘exoplanets’, worlds orbiting alien suns, and you will almost certainly have heard about the Higgs Boson, the particle that imbues all others with mass, which the LHC found this year. But you probably won’t know that (if their findings are taken to their logical conclusion) these machines have also detected hints that Elvis lives, or that out there, among the flaming stars and planets, are unicorns, actual unicorns with horns on their noses. There’s even weirder stuff, too: devils and demons; gods and nymphs; places where Hitler won the Second World War, or where there was no war at all. Places where the most outlandish fantasies come true. A weirdiverse, if you will. Most bizarre of all, scientists are now seriously discussing the possibility that our universe is a fake, a thing of smoke and mirrors.
All this, and more, is the stuff of the multiverse, the great roller-coaster rewriting of reality that has overturned conventional cosmology in the last decade or two. The multiverse hypothesis is the idea that what we see in the night sky is just an infinitesimally tiny sliver of a much, much grander reality, hitherto invisible. The idea has become so mainstream that it is now quite hard to find a cosmologist who thinks there’s nothing in it. This isn’t the world of the mystics, the pointy-hat brigade who see the Age of Aquarius in every Hubble image. On the contrary, the multiverse is the creature of Astronomers Royal and tenured professors at Cambridge and Cornell.
First, some semantics. The old-fashioned, pre-multiverse ‘universe’ is defined as the volume of spacetime, about 90 billion light years across, that holds all the stars we can see (those whose light has had enough time to reach us since the Big Bang). This ‘universe’ contains about 500 sextillion stars — more than the grains of sand on all the beaches of Earth — organised into about 80 billion galaxies. It is, broadly speaking, what you look up at on a clear night. It is unimaginably vast, incomprehensibly old and, until recently, assumed to be all that there is. Yet recent discoveries from telescopes and particle colliders, coupled with new mathematical insights, mean we have to discard this ‘small’ universe in favour of a much grander reality. The old universe is as a gnat atop an elephant in comparison with the new one. Moreover, the new terrain is so strange that it might be beyond human understanding.
That hasn’t stopped some bold thinkers from trying, of course. One such is Brian Greene, professor of physics and mathematics at Columbia University in New York. He turned his gaze upon the multiverse in his latest book, The Hidden Reality (2011). According to Greene, it now comes in no fewer than nine ‘flavours’, which, he says, can ‘all work together’.
The simplest version he calls the ‘quilted multiverse’. This arises from the observation that the matter and energy we can see through our most powerful telescopes have a certain density. In fact, they are just dense enough to permit a gravitationally ‘flat’ universe that extends forever, rather than looping back on itself. We know that a repulsive field pervaded spacetime just after the Big Bang: it was what caused everything to fly apart in the way that it did. If that field was large enough, we must conclude that infinite space contains infinite repetitions of the ‘Hubble volume’, the volume of space, matter and energy that is observable from Earth.
There is another you, sitting on an identical Earth, about 10 to the power of 10 to the power of 120 light years away
If this is correct, there might — indeed, there must — be innumerable dollops of interesting spacetime beyond our observable horizon. There will be enough of these patchwork, or ‘pocket’, universes for every single arrangement of fundamental particles to occur, not just once but an infinite number of times. It is sometimes said that, given a typewriter and enough time, a monkey will eventually come up with Hamlet. Similarly, with a fixed basic repertoire of elementary particles and an infinity of pocket universes, you will come up with everything.
In such a case, we would expect some of these patchwork universes to be identical to this one. There is another you, sitting on an identical Earth, about 10 to the power of 10 to the power of 120 light years away. Other pocket universes will contain entities of almost limitless power and intelligence. If it is allowed by the basic physical laws (which, in this scenario, will be constant across all universes), it must happen. Thus there are unicorns, and thus there are godlike beings. Thus there is a place where your evil twin lives. In an interview I asked Greene if this means there are Narnias out there, Star Trek universes, places where Elvis got a personal trainer and lived to his 90s (as has been suggested by Michio Kaku, a professor of theoretical physics at the City University of New York). Places where every conscious being is in perpetual torment. Heavens and hells. Yes, it does, it seems. And does he find this troubling? ‘Not at all,’ he replied. ‘Exciting. Well, that’s what I say in this universe, at least.’
The quilted multiverse is only the beginning. In 1999 in Los Angeles, the Russian émigré physicist Andrei Linde invited a group of journalists, myself included, to watch a fancy computer simulation. The presentation illustrated Linde’s own idea of an ‘inflationary multiverse’. In this version, the rapid period of expansion that followed the Big Bang did not happen only once. Rather, like Trotsky’s hopes for Communism, it was a constant work in progress. An enormous network of bubble universes ensued, separated by even more unimaginable gulfs than those that divide the ‘parallel worlds’ of the quilted multiverse.
Here’s another one. String Theory, the latest attempt to reconcile quantum physics with gravity, has thrown up a scenario in which our universe is a sort of sheet, which cosmologists refer to as a ‘brane’, stacked up like a page in a book alongside tens of trillions of others. These universes are not millions of light years away; indeed, they are hovering right next to you now.
That doesn’t mean we can go there, any more than we can reach other universes in the quantum multiverse, yet another ‘flavour’. This one derives from the notion that the probability waves of classical quantum mechanics are a hard-and-fast reality, not just some mathematical construct. This is the world of Schrödinger’s cat, both alive and dead; here, yet not here. Einstein called it ‘spooky’, but we know quantum physics is right. If it wasn’t, the computer on which you are reading this would not work.
The ‘many worlds’ interpretation of quantum physics was first proposed in 1957 by Hugh Everett III (father of Mark Everett, frontman of the band Eels). It states that all quantum possibilities are, in fact, real. When we roll the dice of quantum mechanics, each possible result comes true in its own parallel timeline. If this sounds mad, consider its main rival: the idea that ‘reality’ results from the conscious gaze. Things only happen, quantum states only resolve themselves, because we look at them. As Einstein is said to have asked, with some sarcasm, ‘would a sidelong glance by a mouse suffice?’ Given the alternative, the prospect of innumerable branching versions of history doesn’t seem like such a terrible bullet to bite.
There is a non-trivial probability that we, our world, and even the vast extensions of spacetime are no more than a gigantic computer simulation
Stranger still is the holographic multiverse, which implies that ‘our world’ — not just stars and galaxies but you and your bedroom, your career problems and last night’s dinner — are mere flickers of phenomena taking place on an inaccessible plane of reality. The entire perceptible realm would amount to nothing more than shapes in a shadow theatre. This sounds like pure mysticism; indeed, it sounds almost uncannily like Plato’s allegory of the cave. Yet it has some theoretical support: Stephen Hawking relies on the idea in his solution to the Black Hole information paradox, which is the riddle of what happens to information destroyed as it crosses the Event Horizon of a dark star.
String theory affords other possibilities, and yet more layers of multiverse. But the strangest (and yet potentially simplest) of all is the idea that we live in a multiverse that is fake. According to an argument first posited in 2001 by Nick Bostrom, professor of philosophy at the University of Oxford, there is a non-trivial probability that we, our world, and even the vast extensions of spacetime that we saw in the first multiverse scenarios, are no more than a gigantic computer simulation.
The idea that what we perceive as reality is no more than a construct is quite old, of course. The Simulation Argument, as it is called, has features in common with the many layers of reality posited by some traditional Buddhist thinking. The notion of a ‘pretend’ universe, on the other hand, crops up in fiction and film — examples include the Matrix franchise and The Truman Show (1998). The thing that makes Bostrom’s idea unique is the basis on which he argues for it: a series of plausible assumptions, plus a statistical calculation.
In essence, the case goes like this. If it turns out to be possible to use computers to simulate a ‘universe’ — even just part of one — with self-aware sentient entities in it, the chances are that someone, somewhere, will do this. Furthermore, as Bostrom explained it to me, ‘Look at the way our computer simulations work. When we run a simulation of, say, the weather or of a nuclear explosion [the most complex computer simulations to date performed], we do not run them once, but many thousands, millions — even billions — of times. If it turns out that it is possible to simulate — or, more correctly, generate — conscious awareness in a machine, it would be surprising if this were done only once. More likely it would be done countless billions of times over the lifetime of the advanced civilisation that is interested in such a project.’
If we start running simulations, as we soon might, given our recent advances in computing power, this would be very strong evidence that we ourselves live in a simulation. If we conclude that we are, we have some choices. I’ll say more on those below.
First, we come to the most bizarre scenario of all. Brian Greene calls it the ‘ultimate multiverse’. In essence, it says that everything that can be true is true. At first glance, that seems a bit like the quilted multiverse we met earlier. According to that hypothesis, all physical possibilities are realised because there is so much stuff out there and so much space for it to do things in.
Those who argue that this ‘isn’t science’ are on the back foot. The Large Hadron Collider could find direct evidence for aspects of string theory within the decade
The ultimate multiverse supercharges that idea: it says that anything that is logically possible (as defined by mathematics rather than by physical reality) is actually real. Furthermore, and this is the important bit, it says that you do not necessarily need the substrate of physical matter for this reality to become incarnate. According to Max Tegmark, professor of physics at the Massachusetts Institute of Technology, the ‘Mathematical Universe Hypothesis’ can be stated as follows: ‘all structures that exist mathematically also exist physically‘. Tegmark uses a definition of mathematical existence formulated by the late German mathematician David Hilbert: it is ‘merely the freedom from contradiction’. Hence, if it is possible, it exists. We can allow unicorns but not arbitrary, logic-defying magic.
I haven’t given the many theories of the multiverse much thought in the past few years just because of the different iterations of it.
Although there is some mysticism tied into the quantum physics theory and ultimately the many theories of the Multiverse(s), the “real” world applications of computers ( and ultimately quantum computing ), quantum teleporting and the experiments performed on the Large Hadron Collider in Europe does indeed put critics of the many variations of the multiverse theories “on the back foot.”
Who’s to say there’s no such thing as a mysterious Universe!
Mexico: UFO in a Mountain Crater?
News Agency) An alleged elongated object entered the crater of the Popocatepetl
Volcano, 65 kilometers distant from the Mexican capital, causing astonishment
and confusion among experts and the public alike.
On October 25 at 20:45
local time, a camera from the TELEVISA TV network that monitors activity in the
giant volcano captured the image and immediately unleashed a firestorm of
discussions. The object’s measurements would have been 1 kilometer long by 200
meters wide, flying at a speed greater than that of an airliner, according to
However, the majority of experts, like astronomer
Julieta Fierro, a renowned science popularizer, took a more skeptical
stance. Fierro believes that it cannot be said for sure if the object fell
within the crater or if it is in fact “a galaxy 20,000 million light years away.
It could be something incredibly distant moving behind the Earth,” she
A similar opinion was voiced by William Lee, a member of the
Mexican Academy of Sciences, who said it was “a video error, given that there
was no visible interaction between the object and the atmosphere and gases
emanating from the volcano.”
Raul Rivera of the Servicio
Meteorologico Nacional (National Weather Service) said it was “an object whose
composition is simply unknown to us.”
[A note from Prof. Ana Luisa
Cid: “Regarding the story of the cylindrical UFO in the volcano, it is worth
noting that it was recorded by the TELEVISA camera (not the same as the one used
by CENAPRED). I am pointing this out because some researchers have published
erroneous reports, thinking it is the same camera with the same specifications.
They further compound their error by saying CENAPRED takes photos every 30
seconds and then joins them to form a time lapse. The truth is that “CENAPRED
used an Pelco brand remotely controlled analog camera. It is a video camera that
takes pictures every 2 seconds approximately before placing them on the
Internet.” This information was directly provided to me by Ing. Gilberto
Castelán, responsible for monitoring maintenance and
Or it could have been a telescopic “hologram” that some ET civilization is using to explore our volcano systems from a nice, safe distance? Like from 50 to 100 light-years away?
Like what we plan to do in a primitive way using the “Square Kilometer Array?”
The above title is a quote attributed to William Thomson, Lord Kelvin in the year 1900. But it is not what Thomson said. It really was said by Albert A. Michaelson, another great 19th Century physicist.
So what is the meaning of all this stuff? The fact that whenever a great scientist(s) proclaims that in our reality, there already has been all that has been discovered in Nature? That the self-same scientists are usually wrong when making such claims?
Yes to the above. And here in the early 21st Century, the more things change, the more they stay the same.:
Physicist Sean Carroll, speaking at James Randi’s “The Amazing Meeting”, tells how anomalous phenomenon simply can’t happen because the laws of physics are completely understood:
There are actually three points I try to hit here. The first is that the laws of physics underlying everyday life are completely understood. There is an enormous amount that we don’t know about how the world works, but we actually do know the basic rules underlying atoms and their interactions — enough to rule out telekinesis, life after death, and so on. The second point is that those laws are dysteleological — they describe a universe without intrinsic meaning or purpose, just one that moves from moment to moment.
The third point — the important one, and the most subtle — is that the absence of meaning “out there in the universe” does not mean that people can’t live meaningful lives. Far from it. It simply means that whatever meaning our lives might have must be created by us, not given to us by the natural or supernatural world. There is one world that exists, but many ways to talk about; many stories we can imagine telling about that world and our place within it, without succumbing to the temptation to ignore the laws of nature. That’s the hard part of living life in a natural world, and we need to summon the courage to face up to the challenge.
There’s a lot of elements to like about the talk, and Sean Carroll is no doubt a smarter man than me, but the pre-emptive debunking of apparent anomalies in science (such as parapsychology and the evidence for the survival of consciousness) – in effect, saying that we need not even test these anomalies because the laws of physics are already understood and preclude them – left me thinking of another well-known scientist’s thoughts on the apparent completeness of science. Considering the alternative scientific viewpoints from the likes of physicist Henry Stapp, on theoretical explorations of the possibility of an afterlife, and Dean Radin’s recent work on conscious influence in the famous double-slit experiment, the famous (though possibly apocryphal) fin de siècle quote of Lord Kelvin immediately came to mind when contemplating Carroll’s pronouncements:
There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.
Within a few years, science was turned on its head by relativity, and followed by quantum mechanics. One can only wonder if current-day anomalies, such as those explored by parapsychologiests, might one-day lead to some similar revolution, this time involving consciousness or information as primary elements of the cosmos.
Although Greg is understandably mistaken about Lord Kelvin’s quote, he is spot on about Carroll’s proclamations and I am surprised that Carroll actually made such claims.
Well, maybe not. I guess it just shows the inherent uber-conversatism in science.
But in the general population, not so much.
I think we might be ready for a new physics that breaks Mankind out into the Universe and answers some of our questions about Consciousness, UFOs, ghosts and other paranormal activities.
As always, many hat tips to Greg Taylor’s Daily Grail.
Sleep-learning, or presenting information to a sleeping person by playing a sound recording has not been very useful. Researchers have determined that learning during sleep is “impractical and probably impossible.” But what about daydream learning?
Subliminal learning is the concept of indirect learning by subliminal messages. James Vicary pioneered subliminal learning in 1957 when he planted messages in a movie shown in New Jersey. The messages flashed for a split second and told the audience to drink Coca-Cola and eat popcorn.
A recent study published in the journal Neuron used sophisticated perceptual masking, computational modeling, and neuroimaging to show that instrumental learning can occur in the human brain without conscious processing of contextual cues. Dr. Mathias Pessiglione from the Wellcome Trust Centre for Neuroimaging at the University College London reported: “We conclude that, even without conscious processing of contextual cues, our brain can learn their reward value and use them to provide a bias on decision making.” (“Subliminal Learning Demonstrated In Human Brain,” ScienceDaily, Aug. 28, 2008)
“By restricting the amount of time that the clues were displayed to study participants, they ensured that the brain’s conscious vision system could not process the information. Indeed, when shown the cues after the study, participants did not recall having seen any of them before. Brain scans of participants showed that the cues did not activate the brain’s main processing centers, but rather the striatum, which is presumed to employ machine-learning algorithms to solve problems.”
“When you become aware of the associations between the cues and the outcomes, you amplify the phenomenon,” Pessiglione said. “You make better choices.” (Alexis Madrigal, “Humans Can Learn from Subliminal Cues Alone,” Wired, August 27, 2008)
What better place for daydream learning than the Cloud? Cloud computing refers to resources and applications that are available from any Internet connected device.
The Cloud is also collectively associated with the “technological singularity” (popularized by science fiction writer Vernor Vinge) or the future appearance of greater-than-human super intelligence through technology. The singularity will surpass the human mind, be unstoppable, and increase human awareness.
“Could the Internet ‘wake up’? And if so, what sorts of thoughts would it think? And would it be friend or foe?
“Neuroscientist Christof Koch believes we may soon find out — indeed, the complexity of the Web may have already surpassed that of the human brain. In his book ‘Consciousness: Confessions of a Romantic Reductionist,’ published earlier this year, he makes a rough calculation: Take the number of computers on the planet — several billion — and multiply by the number of transistors in each machine — hundreds of millions — and you get about a billion billion, written more elegantly as 10^18. That’s a thousand times larger than the number of synapses in the human brain (about 10^15).”
In an interview, Koch, who taught at Caltech and is now chief scientific officer at the Allen Institute for Brain Science in Seattle, noted that the kinds of connections that wire together the Internet — its “architecture” — are very different from the synaptic connections in our brains, “but certainly by any measure it’s a very, very complex system. Could it be conscious? In principle, yes it can.” (Dan Falk, “Could the Internet Ever ‘Wake Up’? And would that be such a bad thing?” Slate, Sept. 20, 2012)
There has been some speculation about what it would take to bring down the Internet. According to most authorities, there is no Internet kill switch, regardless of what some organizations may claim. Parts of the net do go down from time-to-time, making it inaccessible for some — albeit temporarily. “Eventually the information will route around the dead spots and bring you back in,” said IT expert Dewayne Hendricks.
“The Internet works like the Borg Collective of Star Trek — it’s basically a kind of hive mind,” he adds. Essentially, because it’s in everybody’s best interest to keep the Internet up and running, there’s a constant effort to patch and repair any problems. “It’s like trying to defeat the Borg — a system that’s massively distributed, decentralized, and redundant.”
It is debatable whether the ‘Net on it’s own will become sentient or not, but the potential is certainly there and one wonders whether it hasn’t already!

From Foreign Policy:
Last month, Small Wars Journal managing editor Robert Haddick asked whether new technology has rendered aircraft carriers obsolete. Well, not everyone thinks so, especially in science-fiction, where “flat tops” still rule in TV shows like Battlestar Galactica. So FP’s Michael Peck spoke with Chris Weuve, a naval analyst, former U.S. Naval War College research professor, and an ardent science-fiction fan about how naval warfare is portrayed in the literature and television of outer-space.
Foreign Policy: How has sci-fi incorporated the themes of wet-navy warfare? How have warships at sea influenced the depiction of warships in space?
Chris Weuve: There are a lot of naval metaphors that have made their way into SF. They are analogs, models of ways to think about naval combat. When people started writing about science-fiction combat, it was very easy to say that a spaceship is like a ship that floats on the water. So when people were looking for ways to think about, there was a tendency to use models they already understood. As navies have changed over time, that means there is a fair number of models that various science fiction authors can draw on. You have a model that resembles the Age of Sail, World War I or World War II surface action, or submarines, or fighters in space. Combine a couple of those, and you have aircraft carriers in space. I’m not one who gets hung up on the real physics because it is science fiction. But all of these models are based more upon historical analogs then analysis of the actual situation in space.
FP: Let’s reverse the question. Has sci-fi affected the way that our navies conduct warfare?
CW: This is a question that I occasionally think about. Many people point to the development of the shipboard Combat Information Center in World War II as being inspired by E.E. Doc Smith’s Lensman novels from the 1940s. Smith realized that with hundreds of ships over huge expanses, the mere act of coordinating them was problematic. I think there is a synergistic effect. I also know a number of naval officers who have admitted to me that the reason they joined the Navy was because Starfleet Command wasn’t hiring.
FP: How do these different space warfare models differ from their oceanic counterparts?
CW: Science fiction authors and moviemakers tend to gravitate towards historical models they — and their audience — understand. So, sometimes you end up with “submarines in space” — but a submarine is a vessel designed to hide under the water, which obscures your vision and forces you to use capricious sensors like sonar. Space, on the other hand, is wide open, and any ship putting out enough heat to keep its crew alive stands out from the background, if you have enough time to look. Other times we get “dreadnoughts in space,” with gunnery duels like Jutland — but again, hiding is hard, so this battle should take place at extreme range. Or you get “airplanes in space,” which largely ignores that airplanes work in the real world because they take advantage of the fact that air and sea have different attributes.
All of these models are fun, and some work better than others, but they all present space combat in a way that doesn’t really fit with the salient attributes of space. And lest I get a thousand emails from people who say I don’t understand how combat in their favorite universe works — yes, I do. My answers are necessarily approximations for this interview. Someday I should write a book.
The biggest challenge in mounting a space mission to another star may not be technology, but people, experts say.
Scientists, engineers, philosophers, psychologists andleaders in many other fields gathered in Houston last week for the 100 Year Starship Symposium, a meeting to discuss launching an interstellar voyage within 100 years.
“It seems like it would be so hard, and the biggest obstacle is ourselves. Once we get out of our way, once we commit to this, then it’s a done deal,” said former “Star Trek: The Next Generation” actor LeVar Burton, who is serving on the advisory committee of the 100 Year Starship project.
The initiative hopes to spur the development of new propulsion technologies, life support systems, starship and habitat designs, as well as myriad other necessaryinnovations, to send a vehicle beyond our solar system — where no manmade object has yet traveled — and to another star. As the closest stars to the sun are still light-years away, such a feat will be daunting. [How Interstellar Space Travel Works (Infographic)]
But Burton wasn’t the only one who said the most difficult part of interstellar spaceflight may be corralling public and governmental support, and getting the right thinkers to work together to attack the problem.
“I think the greatest challenges are going to be what the greatest challenges in anything are, and that’s the people piece,” said former NASA astronaut Mae Jemison, who was the first African-American woman to travel to space. Jemison is heading the new 100 Year Starship organization, which was founded with seedmoney from the Defense Advanced Research Projects Agency (DARPA).
“The really exciting thing and the scary thing is I know I can’t do it by myself, but there are a lot of people who want to help,” Jemison added.
Interstellar spaceflight for humanity isn’t inevitable, she said — merely imperative.
“We could screw it up,” Jemison told Space.com. “We could decide not to do it. But I can tell you what, if we don’t figure out how to do it, then we probably aren’t going to be around to worry about whether the sun turns into a red gas giant. Unless we find some focal aspiration that pushes us further, that helps us see ourselves as a species that we should be cooperating with, we’re going to be in trouble.”
Plus, if human beings can solve the challenges of interstellar spaceflight, in the process they will have solved many of the problems plaguing Earth today, experts said. For example, building a starship will require figuring out how to conserve and recycle resources, how to structure societies for the common well-being, and how to harness and use energy sustainably.
Perhaps the 100 Year Starship Symposium should partner up with the Build The Enterprise Project? They have a 100 year timeline also and I couldn’t think of a better marriage.
HOUSTON — A warp drive to achieve faster-than-light travel — a concept popularized in television’s Star Trek — may not be as unrealistic as once thought, scientists say.
A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre; however, subsequent calculations found that such a device would require prohibitive amounts of energy.
Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially bringing the idea back from the realm of science fiction into science.
An Alcubierre warp drive would involve a football-shape spacecraft attached to a large ring encircling it. This ring, potentially made of exotic matter, would cause space-time to warp around the starship, creating a region of contracted space in front of it and expanded space behind. [Star Trek’s Warp Drive: Are We There Yet? | Video]
Meanwhile, the starship itself would stay inside a bubble of flat space-time that wasn’t being warped at all.
“Everything within space is restricted by the speed of light,” explained Richard Obousy, president of Icarus Interstellar, a non-profit group of scientists and engineers devoted to pursuing interstellar spaceflight. “But the really cool thing is space-time, the fabric of space, is not limited by the speed of light.”
With this concept, the spacecraft would be able to achieve an effective speed of about 10 times the speed of light, all without breaking the cosmic speed limit.
The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.
But recently White calculated what would happen if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring. He found in that case, the warp drive could be powered by a mass about the size of a spacecraft like the Voyager 1 probe NASA launched in 1977.
Furthermore, if the intensity of the space warps can be oscillated over time, the energy required is reduced even more, White found.
“The findings I presented today change it from impractical to plausible and worth further investigation,” White told SPACE.com. “The additional energy reduction realized by oscillating the bubble intensity is an interesting conjecture that we will enjoy looking at in the lab.”
This is a boon and a most fortuitous opportunity if it’s the real deal. But like most things in the real world, there is something that is an essential ingredient in any research project.
