That’s how Nature puts it.
Black holes made him famous, right? Hawking radiation and all.
Anyway, he says now, there are no black holes as we understand them. From Nature:
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 probably 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, the physicist, based at the University of Cambridge, UK, and 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.
In its stead, Hawking’s radical proposal is a much more benign “apparent horizon”, which only temporarily holds matter and energy prisoner before eventually releasing them, albeit in a more garbled form.
Other physicists are skeptical: Black hole expert Don Page says “Hawking is opening the door to a scenario so extreme ‘that anything in principle can get out of a black hole.’ Joseph Polchinski doubts that black holes without an event horizon could exist in nature, and Raphael Bousso says Hawking’s new proposal is in some ways “an even more radical and problematic suggestion” than another one proposed by quantum physicists (“firewalls”).
Is it just me or do others find that all this feels fundamentally unserious? It feels like something strutting down the catwalk looks. – O’Leary for News
