Stephen Hawking questions nature of black holes
Notion of ‘event horizon’ from which nothing can escape is incompatible with quantum theory, physicist claims.
Most physicists foolhardy enough to write a paper claiming that “there are no black holes” — at least not in the sense we usually imagine — would likely be dismissed as cranks. But when the call to redefine these cosmic crunchers comes from Stephen Hawking, it’s worth taking notice. In a paper posted online today, one of the creators of modern black-hole theory does away with the notion of an event horizon, the invisible boundary thought to shroud every black hole, beyond which nothing, not even light, can escape.
