Cynthia McKanzie– The idea that parallel universe may be hidden inside supermassive black holes is very intriguing.
The theory that several invisible worlds surround our own universe has been put forward by scientists on many occasions, but no-one has so far been able to find conclusive proof of the existence of parallel universes.
Many prominent scientists now suggest that black holes could be portals to a multitude of universes beyond our own. One reason why we haven’t yet been able to discover parallel universe is simply because they are hidden inside supermassive black holes.
Famous theoretical physicist and cosmologist Stephen Hawking has argued in favor of the parallel universe theory for many years. It has previously been assumed that anything that falls into a black hole would be destroyed and lost forever, but Hawking is of a different opinion.
Hawking suggests the black holes are not as black as previously thought. In his opinion, it is highly possible that something fall through black holes, without being destroyed and enter a parallel universe.
To explain how information can escape from a black hole is a challenge. Stephen Hawking calculated that black holes eventually must end. According to his calculations, the black holes eventually begin to leak information and eventually explode, which would release the trapped particles in any form.
“That way out wouldn’t take people back to where they’d come from, he said. Instead, they would reappear, but somewhere else – perhaps even in an alternative universe.
“The existence of alternative histories with black holes suggests this might be possible. The hole would need to be large and if it was rotating it might have a passage to another universe. But you couldn’t come back to our universe,” Hawking explained. “Black holes are not eternal prison as we once thought. If you feel you are trapped in a black hole, don’t give up. There is a way out,” Stephen Hawking said
What cosmologists call the multiverse is a consequence of the eternal inflation theory according to which our universe grows. The eternal inflation theory is an extension of the Big Bang theory and suggests that during its early phase, space-time expanded exponentially, doubling in volume every fraction of a second before settling into a more sedate rate of growth.
According to eternal inflation, the inflationary phase of the universe’s expansion lasts forever throughout most of the universe.
Since the regions expand exponentially rapidly, most of the volume of the universe at any given time is inflating.

Cosmologists say that even after rapid expansion ended in our cosmos, a number of bubbles could keep inflating into their own baby universes. Each of these would give rise to other bubbles, spawning a sprawling multiverse.
“While inflation is going on, bubbles can pop out and expand in this inflating space,” says cosmologist Alex Vilenkin of Tufts University in Medford, Massachusetts, one of the pioneers of inflationary cosmology.
In other words – this fascinating theory suggests could be surrounded by an infinite number of invisible worlds.
The problem with this theory is it’s very difficult to obtain proof. Cosmologists have suggested that bubbles colliding with our universe could have left imprints in the cosmic microwave background, the leftover radiation of the big bang. However, such a signal would be very faint, and no conclusive evidence has yet been seen.
If there is a parallel universe inside a black hole, it’s fate depends on its size. Bubbles that formed later would be smaller, and should collapse into standard black holes, with nothing inside apart from an infinitely dense point called a singularity.
But earlier bubbles would be bigger and would create larger black holes that conceal their own inflating universes.
For the first fractions of a second after inflation ended in our patch of space-time, when the bubbles began collapsing, we would have been connected to their interiors via wormholes.
Unfortunately, these wormholes would have closed almost immediately, cutting off the inflating universes within. “The opportunity has passed for us to send signals to these other universes,” says co-author Jaume Garriga of the University of Barcelona, Spain.
However, according to a newer theory, scientists now consider that the largest of the black holes that hide a universe within them would have started out much bigger than is otherwise possible. These giants could have grown to become the supermassive black holes we see today at the heart of galaxies, including our own Milky Way.
Don Marolf, who studies general relativity and black holes at the University of California Santa Barbara, points out that physicists have long wondered whether black holes conceal more than they reveal at their surfaces.
“This is essentially an extreme example of an ancient point, that black holes can have enormous interiors,” Marolf said.
Our universe could even look like a black hole to physicists in some other universe.
“This subject is really, really deep,” Linde said. “We are just starting to touch the surface and discover new things about the multiverse.”
There are also there are physicists who consider the possibility that some most advanced races – super aliens could live inside supermassive black holes.
“Interiors of super massive black holes may be inhabited by advanced civilizations living on planets with the third-kind orbits,” Russian cosmologist Vyacheslav I. Dokuchaev at Moscow’s Institute for Nuclear Research of the Russian Academy of Sciences
“We could live inside a super massive black hole eventually… but super-aliens may have already beaten us to it,” claims Dokuchaev. His controversial theory is not based on science-fiction but on Einstein’s theories.
What today may sound like science fiction can be treated as science tomorrow – if evidence can be obtained.
