Stephen Hawking: 'there are no black holes'

Prof Hawking has published a new paper suggesting that the accepted view about black holes is wrong.
Well known for his work on the subject, the world-famous physicist is attempting to reconcile the behavior of a black hole under both basic gravitational theory and quantum theory to produce a single unified system.

According to Hawking, under gravitational theory the event horizon of a black hole is such that nothing, not even light, can escape from it. Under a more recent quantum theory interpretation however, the event horizon of a black hole would instead be a seething mass of high-energy particles that would incinerate anything that it touched.

Combining these concepts, Hawking came up with the idea of an "apparent horizon" with no fixed boundary, while re-branding the term "black hole" to the less absolute "grey hole".

"The absence of event horizons means that there are no black holes in the sense of regimes from which light can't escape to infinity," he wrote. "There are however apparent horizons which persist for a period of time. This suggests that black holes should be redefined as metastable bound states of the gravitational field."

Perhaps his next discovery will be, "There is no Hawking."

I'm at least as uninformed as you are but I'm still pulling for "opens a wormhole and big bangs a new universe in another region of space-time" I'm pulling for a new universe itself. Accelerated implosion turns into accelerated expansion from the perspective on an insider.

I have the urge to re-read 'A Brief History of Time' and insert [There are no Black Holes] every time he mentions them.

Again, Hawking did not say there were no black holes.

Again, Hawking did not say there were no black holes. How do people keep missing that?

His theory on no god but aliens i believe. this one maybe not.. What's wrong with the hypothetical scenario of hostile aliens? What does evolution drive creatures to do? Attain top predator, and that results in violence quite often.

How do people keep missing that? I don't know, but a better question might be, why is it that no news source can ever find a reporter that actually understands the basics of science to report on science stories?
