In modern science, the prevailing opinion supposes that whatever falls into a black hole disappears forever and breaks apart into the component parts. However, a new theory states that black holes do not destroy the matter but rather are a kind of exit gate which lead to other universes just like our own.
The new theory was developed by Jorge Pullin of the State University of Louisiana and Rodolfo Gambino of the University of the Republic of Uruguay. The two scientists decided to study the predictions of the theory of quantum gravity in black holes. More specifically, they applied the equations of quantum gravity in a non-rotating black hole with spherical symmetry.
As described in other theories, as the matter approaches the core of the black hole, the gravitational field becomes more and more powerful, but it does not disappear into a spacetime singularity as the prevailing theory states. According to the study results of the two researchers, the matter does not disappear in the middle of the hole but continues its way up the other end and into another universe.
“Like part of a cosmic Russian doll, our universe may be nested inside a black hole that is itself part of a larger universe. In turn, all the black holes found so far in our universe—from the microscopic to the supermassive—may be doorways into alternate realities.”
