If the title of an article ends in a question mark, then the answer usually is ‘no.’ Mike Wall on Stephen Hawking’s latest theory to solve a long-standing mystery.
Einstein’s theory of general relativity predicts that the physical information about material gobbled up by a black hole is destroyed, but the laws of quantum mechanics stipulate that information is eternal. Therein lies the paradox.
Hawking’s solution to the mystery:
I propose that the information is stored not in the interior of the black hole, as one might expect, but on its boundary, the event horizon… The information about ingoing particles is returned, but in a chaotic and useless form. For all practical purposes, the information is lost.
Hawking on portals to other universes:
The hole would need to be large, and if it was rotating, it might have a passage to another universe. But you couldn’t come back to our universe. So, although I’m keen on spaceflight, I’m not going to try that.
Remember, these theories are part of the scientific process, therefore, theories; not scientific fact.
