Hawking Changes His Mind on Black Holes

But now, according to his latest revision, Hawking argues that eventually some of the information about the black hole can be determined from what it emits.

The information has important philosophical and practical consequences.

The laws of quantum physics, stating that so-called information can never be completely destroyed, RULES ! Previously Hawkings concluded that black holes bend the laws to their will. Hawkings hasn't revealed his new theory.

Wait for a reversal to the Big Bang theory !

Should we really trust everything this man says ?

I mean Stephen Hawking not Max Habibi.

C'mon he has starred in The Science of Star Trek as himself and in the Simpsons.



Dr Stephen Hawking action figure.

The about-turn might cost Hawking, a physicist at the University of Cambridge, an encyclopaedia because of a bet he made in 1997.

I wonder if Hawking's solution has to do with the fact that matter never actually quite reaches the event horizon.

As were all the crazy bastards who advocated the circular nature of the world. But the flat-earth society guys: now those guys had stick-to-it-ness

Hawkins initially said that time-machine is not possible, but then sometime back (1-2 yr back), I read that as per him time-machine might be possible.

So I am not surprised if he goes ahead and counter his own theory.

After all physics is nothing but practical example of error-and-trial method

Curt Cutler, from the Albert Einstein Institute in Golm, Germany, which is chairing the meeting in Dublin, told New Scientist magazine that Hawking asked at the last minute for permission to address the conference.

"He sent a note saying `I have solved the black hole information paradox and I want to talk about it,'" Cutler said.


They managed to squeeze him in at the last moment.

Hawking Fills World In on Theory of Black Hole Blowouts

Hawking's answer is that the black holes hold their contents for aeons but themselves eventually deteriorate and die. As the black holes disintegrate, they send their transformed contents back out into the infinite universal horizons .

Paradox lost

Dr Preskill of the California Institute of Technology is the proud new owner of a set of encyclopedias on baseball from which he can "recover information at will".

Hawking also said that he was relieved to, after 30 years, finally have this solved.

What did he solve? It's all still theory. No one knows. He could change his mind next week.

I say this in no way disrespecting Hawking, btw. He is a briliant man.

It's a pity Einstein didn't admit he was wrong all those years ago. He could have saved the scientific community some time [and money ?] . Most scientists seem to lean towards Hawking's thinking so far.

As late as 1947 many leading scientists thought that an aircraft would not be able to penetrate the sound barrier without being torn to pieces.

The point is scientific theory and scientific fact are often very different.

My theory is that my brain falls into a blackhole every Sunday night and that explains why even the simplest tasks on Monday morning are nigh unto impossible. Except, of course, on Mondays mornings that I don't have to go to work.

Huh? Hawking's theories don't contradict Einstein's. In fact, this latest finding tends to confirm Einstein's intuition about "god not playing dice" - a random quantum collapse (god rolling dice) fails to conserve information, and this finding makes it more likely that the quantum collapse that Einstein objected to is in fact incorrect.

It just seemed to overpower all [my] posts.
But it's back by popular demand..

I believe Einstein in later years expressed regret for writing that letter to Roosevelt on how to construct the nuclear bomb.

And they're not black, but a really, really, really dark grey.
