Black holes portals to other universes?
Scientists have proposed a new theory that suggests black holes may actually be the portals to other universes.
Physicists Rodolfo Gambini of University of the Republic in Montevideo, Uruguay, and Jorge Pullin of Louisiana State University have applied the theory of Loop Quantum Gravity (LQG) to a simplified black hole.
In so doing, they suggested that instead of a singularity existing at its centre, there is a portal to another universe.
For many years theoretical physicists have believed that the universe came about as a result of a single Big Bang event —Einstein’s theories suggested it was so. However, the theory of general relativity can't describe what came before the singularity, which should exist at the point in time just before the Big Bang. Theory also suggests that a similar singularity should exist at the centre of black holes, but general relativity fails to describe them properly, phys.org reported.
In this new effort Gambini and Pullin applied LQG to a simplified model of a black hole. Their experiment showed that everything that was pulled into the black hole didn’t compress to a singularity after all-instead it was compressed to a certain small size, then was spit out in another part of the universe or into another universe.
