Stephen Hawking questions nature of black holes

Hawking has some interesting questions about the nature of black holes. These objets are the most intriguing in the Universe at this moment, as we know very little about their nature.

Recent discoveries in Cosmology may lead to more questions about these strange and fascinating objets. In a frequent basis, every discovery reveals an answer but along with it more questions arise.

Such is the nature of Science.

The defining characteristic of a black hole may have to give, if the two pillars of modern physics — general relativity and quantum theory — are both correct.

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 the University of Cambridge, UK, physicist, 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 new proposal is a much more benign “apparent horizon”, which only temporarily holds matter and energy prisoner before eventually releasing them, albeit in…
