Equations predict that our universe may sit in another's black hole.
Therefore , all the black holes found in our universe may also be doorways into other realities. According to this out-of-this-world theory, a black hole is actually a wormhole between universes. It has been predicted that matter attracted by black holes collapses into a single point. However, this new theory contradicts this prediction and states that matter rather gushes out of a "white hole" at the other end of the black one.
Indiana university physicist Nikodem Poplawski presented new mathematical models of the spiraling motion of matter falling into a black hole. His equations suggest such wormholes are viable alternatives to the "space-time singularities" that Albert Einstein predicted to be at the centers of black holes. Einstein's equations for general relativity states that singularities are created whenever matter in a given area gets too dense, as would occur at the ultradense core of a black hole. It also implies that singularities take up no space and are infinitely dense and hot. If Poplawski's theory is correct, they may no longer need to be. New equations suggest that the matter black holes absorb and apparently destroy is actually expelled and becomes the building materials for galaxies, stars, and planets in an alternate reality.
Are black holes actually white?
Stephen Hawking's newest discovery says yes. It suggests that black holes radiate heat through quantum effect. The theory states that the temperature of a black hole varies inversely to its mass. "They glow like hot bodies, and the smaller they are, the more they glow."
