What if black holes are in fact cosmic doorways that lead into different universes and alternate realities? According to a study published in the journal Physics Letters B, this might just be the case.
Think of it as a cosmic Russian doll.
There is a strong possibility that ver black hole in the universe is, in fact, a doorway to another universe. For example, our universe may be located inside a black hole that in turn is part of a much larger universe, that universe could be part of another one and so on. This means that all black holes found in the universe until today, from the smallest to the biggest size could, in fact, be cosmic doorways that lead into alternate realities.
The new mind-boggling theory proposes that a black hole can be utilized as a tunnel, or in other words, as a wormhole between multiverses. Researchers propose that the matter attracted by a black hole does not collapse into a single point as previously thought but gushes out a ‘white hole’ at the other end of the black one.
According to Nikodem Poplawski’s equation, wormholes could prove to be viable alternatives to the ‘space-time singularities’ proposed by the great Albert Einstein, which according to him, are located at the centers of black holes through the universe.
According to the theory proposed by Einstein, singularities do not take up any space, are believed to be infinitely dense are infinitely hot. ‘Singularities’ are created whenever matter in a certain region becomes overly dense, just as it is believed to occur at the ultradense center of a black hole. This concept has been supplied by numerous lines of ‘evidence’ yet numerous scientists around the globe have found it hard to believe let alone accept.
However, If the theory proposed by Poplawski is correct, scientists would no longer have to remain skeptical. According to new equations, the matter absorbed by a certain black hole and is consequently ‘destroyed’ is actually expelled and eventually turn into the building blocks for stars, galaxies, planets in an entirely different reality.
Poplawski is certain that accepting black holes as wormholes could explain numerous mysteries in today’s views of cosmology. Among those mysteries is the big bang. According to scientists, the universe began as a singularity, but researchers have no satisfying explanation of how it is possible for such a singularity to form in space.
Poplawski says that if our universe was created by a white hole instead of the proposed singularity, “it would solve this problem of black hole singularities and also the big bang singularity.”
Interestingly, according to Poplawski not only does his theory explain the Big Bang, but it also could explain the second most powerful explosion in the universe after the ‘Big Bang’; Gamma Ray Bursts.
Gamma Ray Bursts are considered to occur at the fringes of the known universe and are believed to be associated directly with supernovae in faraway galaxies, their true source and origin, however, remains a profound mystery for scientists.
According to Dr. Poplawski, his theory could explain the Gamma Ray Bursts as well. Poplawski proposes that the bursts we are registering might actually be discharges from other universes. According to Poplawski, the matter might be escaping into our universe through supermassive black holes — aka doorways to universes — at the heart of other galaxies.
Testing the… untestable?
But, how can we test the theory proposed by Dr. Poplawski? Well, there is a way to see if he is onto something. Some of the black holes found in our universe actually rotate, and, if our universe was created inside a similarly revolving black hole, then the universe in which we exist, should have inherited the parent objects rotation.
“If future experiments reveal that our universe appears to rotate in a preferred direction, it would be indirect evidence supporting the wormhole theory,” said Poplawski.
The new model proposed by Poplawski isn’t the first to propose that other universes exist inside black holes. Damien Easson, a theoretical physicist at Arizona State University, has theorized about this possibility in previous studies.
“What is new here is an actual wormhole solution in general relativity that acts as the passage from the exterior black hole to the new interior universe,” said Easson, who was not involved in the new study.
“In our paper, we just speculated that such a solution could exist, but Poplawski has found an actual solution,” said Easson, referring to Poplawski’s equations.
Nevertheless, the idea is still very speculative, Easson said to National Geographic in an email.
“Is the idea possible? Yes. Is the scenario likely? I have no idea. But it is certainly an interesting possibility.”
While the theory is certainly interesting and might turn out to become one day, the perfect script for a science fiction movie, it still does not explain the origins of our universe.
According to Andreas Albrecht, a physicist at the University of California, it does not explain how the ‘parent universe’ came into existence or why it has the characteristics and properties it has, the same characteristics and properties our universe supposedly inherited.
“There’re really some pressing problems we’re trying to solve, and it’s not clear that any of this is offering a way forward with that,” he said.
It seems that after all, these revolutionary theories propose mind-altering concepts that are very likely and improbable at the same time. The truth is that with each new theory proposed by researchers that tries to explain how ‘everything’ came into existence, new questions arise that fuel the mystery even further.
