Mysteries about space and universe still remain unsolved. Where are we exactly in this universe? How big this universe could be? Are there people like us on some other planets?.... these are some questions that tickle our imagination when we think about it. Existing theories suggest that the universe is expanding..!! Scientists trying to explain the accelerating expansion of the universe usually point to dark matter which is they say is pushing everything apart.
But an Indiana University has a new theory now. According to it " we are living inside a black hole, that exists in another universe.To be specific a black hole that rebounded like a spring".
It gives you goose bumps just by imagining ourselves living inside a black hole isn't it....??
But there is some serious physics involved in this theory.Nikodem Poplawski of Indiana
University Bloomington, the scientist who presented this theory used a modified version of Einstein’s general relativity equation set that takes particle spin into account.
Including this variable makes it possible to calculate torsion, part of the geometry of space-time. There is a phenomenon which general relativity can not explain called black hole singularity.
Surprisingly this theory of Nikodem Poplawski explains that too....!!
In an earlier study Poplawski said when the density of matter reaches epic proportions, torsion counters gravity. This prevents matter from compressing indefinitely to a singularity of infinite density. Instead, matter rebounds like a spring, and starts expanding again.
Now in his latest study his calculations show that space-time inside the black hole expands to about 1.4 times its smallest size in as little as 10-46 seconds -- two orders of magnitude faster, for lack of a better word, than the Planck time. This brisk bounce-back could have been what led to the expanding universe that we see today.
But the vhilling outcome of Poplawski's theory says we may not be living in our universe at all; we might be living inside a rebounded black hole that exists in a different universe....!!!!!
We could tell by measuring the preferred direction of our universe. A spinning black hole would have imparted some spin to the space-time inside it, which would violate a law of symmetry that links space and time. This might explain why neutrinos oscillate between their antimatter and regular-matter states.
"Maybe the huge black holes at the centre of the Milky Way and other galaxies are bridges to different universes," Poplawski says. If that is correct - and it's a big "if" - there is nothing to rule out our universe itself being inside a black hole.
