Black Holes May Be Exits to another Universe, Stephen Hawking Says

A newly published paper co-authored by Stephen Hawking suggests that black holes may actually be exits that could potentially lead to another universe. The world-famous professor has theorized that black holes aren't exactly weird as previously thought.

"Black holes are not the eternal prisons they were once thought. If you feel you are trapped in a black hole, don't give up. There is a way out," Hawking said in a speech last year as quoted by Independent.

"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."

Previous notion about black holes suggests that everything that crosses the black hole's path gets destroyed. But we many no longer have to fear black holes after all as indicated in Hawking's paper featured in peer-reviewed Physical Review Letters. Co-authoring the paper were Harvard University physics professor Andrew Strominger and Cambridge University professor of theoretical physics Malcolm Perry.

Hawking had earlier challenged the notion in the 1970's when he put forward his idea that radiation may actually find a way to escape from the previously-dreaded black holes thank to the laws of quantum mechanics.

In other words, when black hole absorbs half of a particle-antiparticle pair, the other particle dissipates into vastness of outer space. Hawking also proposed that around a black hole is a 'halo of soft hair' which captures information on anything that comes in, Science Alert reported.

"The Universe, like a kind of supercomputer, is supposed to be able to keep track of whether one car was a green pickup truck and the other was a red Porsche, or whether one was made of matter and the other antimatter," explained Dennis Overbye as quoted in an article piece featured in the New York Times.

"These things may be destroyed, but their 'information' - their essential physical attributes - should live forever."
