Is Our Universe Inside A Black Hole?

Whether you consider the question an issue of philosophy or physics, the problem sets fire to many things and rankles many people.

One of which is the topic of ‘time’ itself. Is there such a thing as time? Is there an “arrow” of time that points only to the “future?” Is time an illusion? Is time only our immediate perception of “now?”

In this paper written by Nikodem Poplawski at Indiana University, the question of how our Universe was created and the problem of time is attempted to be answered:

“Accordingly, our own Universe may be the interior of a black hole existing in another universe.” So concludes Nikodem Poplawski at Indiana University in a remarkable paper about the nature of space and the origin of time.

The idea that new universes can be created inside black holes and that our own may have originated in this way has been the raw fodder of science fiction for many years. But a proper scientific derivation of the notion has never emerged.

Today Poplawski provides such a derivation. He says the idea that black holes are the cosmic mothers of new universes is a natural consequence of a simple new assumption about the nature of spacetime.

Poplawski points out that the standard derivation of general relativity takes no account of the intrinsic momentum of spin half particles. However there is another version of the theory, called the Einstein-Cartan-Kibble-Sciama theory of gravity, which does.

This predicts that particles with half integer spin should interact, generating a tiny repulsive force called torsion. In ordinary circumstances, torsion is too small to have any effect. But when densities become much higher than those in nuclear matter, it becomes significant. In particular, says Poplawski, torsion prevents the formation of singularities inside a black hole.

That’s interesting for a number of reasons. First, it has important implications for the way the Universe must have grown when it was close to its minimum size.

Astrophysicists have long known that our universe is so big that it could not have reached its current size given the rate of expansion we see now. Instead, they believe it grew by many orders of magnitude in a fraction of a second after the Big Bang, a process known as inflation.

The problem with inflation is that it needs an additional theory to explain why it occurs and that’s ugly. Poplawski’s approach immediately solves this problem. He says that torsion caused this rapid inflation.

That means the universe as we see it today can be explained by a single theory of gravity without any additional assumptions about inflation.

Another important by-product of Poplawski’s approach is that it makes it possible for universes to be born inside the event horizons of certain kinds of black hole. Here, torsion prevents the formation of a singularity but allows a HUGE energy density to build up, which leads to the creation of particles on a massive scale via pair production followed by the expansion of the new universe.

This is a Big Bang type event. “Such an expansion is not visible for observers outside the black hole, for whom the horizon’s formation and all subsequent processes occur after infinite time,” says Poplawski.

For this reason, the new universe is a separate branch of space time and evolves accordingly.

Incidentally, this approach also suggests a solution to another of the great problems of cosmology: why time seems to flow in one direction but not in the other, even though the laws of physics are time symmetric.

Poplawski says the origin of the arrow of time comes from the asymmetry of the flow of matter into the black hole from the mother universe. “The arrow of cosmic time of a universe inside a black hole would then be fixed by the time-asymmetric collapse of matter through the event horizon,” he says.

In other words, our universe inherited its arrow of time from its mother.

He says that daughter universes may inherit other properties from their mothers, implying that it may be possible to detect these properties, providing an experimental proof of his idea.

Personally I’m from the school of thought that theorizes “time” is just a perception by the Observer and that the Universes’ chance of producing observers is equal to not producing observers.

Confusing, eh?

Why Our Universe Must Have Been Born Inside a Black Hole

  1. I’m with you, Dad. Time is probably my favorite topic in physics — and in general. I believe our perception of time sees it as one way, and obviously our physical universe seems to move forward and ‘age’, but I think that Time itself runs both ways, and that while we are under the assumption that decisions made only affect the future, it may be possible that our decision also effect the past. So perhaps certain forms of data are sent ‘back’ (though I do not believe there actually is a backwards and forwards in regards to Time).

    I read recently, and I’ll have to find it later, that research has shown that the impulse to do something, say, moving your arm, is made a fraction of a second before we mentally decide to do it. Perhaps this gives some plausibility that information goes both ways.

    And then there is the matter of ‘present’ time which really doesn’t exist. There is no “now”, only what has happened and what is to come. Take for example that light takes time to travel, regardless of how short the distance. even looking at this computer screen which is a about 2 feet from my face is looking into the past, as it takes light time to get from the screen to my eyes. It is imperceptible to us that this is happening, but our uperception of the present is really the very recent past.

  2. I like the Biocentrism Theory of Dr. Robert Lanza in which all existence is just perception by our consciousness, even time and space.

    But I have to play Devil’s Advocate a little and throw the Second Law of Thermodynamics and Entropy into the mix.

    Oh well, no theory is perfect!

  3. Only the bleeding obvious… would be the truth of this link to , Black Holes being the impetus for the opening of a New Universe.
    Matter and energy to fuel the big bang theory.
    The real questions … Remain…

    Where ,or How , can this newly created infinity be measured in some relatable way to the context of understanding dimensional relativity.
    Simply , How to … Measure, another universe , or Dimension.

  4. A time machine wormhole requires that it be built in the present and maintained such that someone in the future can use it to return or visit the past which is your present location which is the other end of the same machine. After this is completed, then it needs to be able to send your high plasma particles along a narrow quantum beam billions of degrees kelvin where the past motion the earth sun and galaxy took until ultimately only temperature is the absolute universe reality

  5. im not a scientist or even that smart (I.Q. only 118) i am just an artist who, inbetween drawing stuff has the occasional lamen lightening bolt thought or idea, this black hole theory gave me one or two sucjh thoughts. if its true, do u think that maybe inside a black hole in our universe, lies another black hole containing a universe that is in fact our own universes mother universe? anythings possible. also does time pass at different rates in other universes than ours?

  6. the radius is directly proportional to the mass of a black hole. the slower time will appear to pass to an observer watching someone falling into a black hole. as they near the event horizon, they will become almost frozen. Time slows under increased gravity and relativistic motion nearing light speed. tiny atomic mini-black holes briefly form and evaporate very fast, and it is difficult to speculate if a mini-black hole is a tiny universe with accelerated time passage? Larger black holes are colder in temp, because temp is inverse to mass. it is believed that absolute zero T is never reached and that the increments towards absolute zero are very small. Also what people are calling black holes, might in fact be white holes, said a famous scientist recently !
