Is our Universe a black hole?
Many science fiction novels and films have suggested that black holes are warps to other dimensions and universes. Although this fantasizing was given power by the mystery surrounding black holes and our inability to actually into them and the mechanics inside, it has been a fairly unsupported idea. However, just recently an Indiana Scientist, Nikodem Poplawski, has come up with a new theory that may explain the constant expansion of our universe. Poplawski says; "Maybe the huge black holes at the centre of the Milky Way and other galaxies are bridges to different universes" and proposes the rebound of balck holes.
Einstein's General Theory of Relativity states that black hole are singularities where matter reaches "infinite density" but equations tend to break down in such circumstances. With a modified version of Einstein's theory Poplawski theorizes that when the density of matter becomes so great, such as in a black hole, torsion of space counters gravity and causes the black hole to rebound and expand. This expansion would explain the expansion of the universe normally attributed to dark matter as well as being calculated to be similar in velocity (growing 1.4 times its smallest size in 10-46 seconds
With these implications, it is entirely possible that we would not be living in a universe at all but in a rebounding black hole within a completely different universe.
We theoretically can prove this by measuring the preferred direction of our universe. By existing within a spinning black hole we would gain some imparted spin in our own space time that would be unexplainable without an outside force. The law of symmetry dictates that___. This spin might explain why neutrinos change between their antimatter and matter states
Can we find other universes in black holes we already know about? Unfortunately not. Space time is so warped and distorted around a black hole that we would only "see" into one once an infinite amount of time had passed. A fairly well known fact is that the gravitational pull of a black hole is so great that it is impossible for light to escape it. This means that some of the most massive light emitting sources in our universe could be, in this way, invisible. This obviously halts active observation on what actually takes place inside a black hole. However, with closer study of subatomic particles and the nature of anti-matter we may be able to discover, what exactly goes on inside of black holes, and possibly, outside of our own.
