Hawking Flips on Black Hole Theory

By Discovery News



July 16, 2004 — It may be time to shift thinking on black holes, for decades believed to be sucking maws in space from which even light cannot escape. Noted physicist Stephen Hawking, who has long argued just that, now says he was wrong: black holes may ultimately allow something to get free.


<snip>

Now, Hawking is saying that black holes don't eat everything, according to New Scientist. They emit radiation for a long time before eventually opening up and allowing some information out.

Gary Gibbons, a colleague of Hawkings' at Cambridge College, attended the lecture at which Hawkings revealed his new theory. He told New Scientist that unlike the decades-old black hole model, in the new model there is no clearly-defined event horizon that hides the information contained in black holes.

1. He is a flip flopper?

Oh no. Well there goes his credibility.

[Tellurian]

4. No...I don't think so. I think he's on the brink of something

but doesn't quite know himself. He used the opportunity as a heads up, he was onto something new...

[LiberalCat]

5. My thoughts exactly.

The sheeple believe it is very bad to use your brain and rethink your position.

[Tellurian]

24. Yep, here it is...Hawking comes through...

Hawking: black holes mangle matter, energy

July 21, 2004 | DUBLIN, Ireland --

Famed astrophysicist Stephen Hawking said Wednesday that black holes, the mysterious massive vortexes formed from collapsed stars, do not destroy everything they consume but instead eventually fire out matter and energy "in a mangled form."

Hawking's radical new thinking, presented in a paper to the 17th International Conference on General Relativity and Gravitation in Dublin, capped his three-decade struggle to explain an elemental paradox in scientific thinking: How can black holes destroy all traces of consumed matter and energy, as Hawking long believed, when subatomic theory says such elements must survive in some form?

Hawking's answer is that the black holes hold their contents for eons but themselves eventually deteriorate and die. As the black hole disintegrates, they send their transformed contents back into the infinite universal horizons from whence they came.

Previously, Hawking, 62, had held out the possibility that disappearing matter travels through the black hole to a new parallel universe -- the very stuff of most visionary science fiction.

10. Yup- he voted for the event horizon before he voted against it

2. Hawking = Chauncey Gardner

Except Hawking has a Norwegian accent.

a favorite movie of mine!

Sorry, had to... that is all.

19. Oh thanks- this is really funny...

...I'm laughing like hell- this is good stuff...

[DrWeird]

6. Um, Hawking's the guy who postulated that black holes...

...emit radiation. Not coincidentaly, it's called Hawking radiation. That was some thirty plus years ago, and is what he is famous for. Leave it to journalists to fuck everything up.

[demoman123]

7. According to the article, he now says they emit "information"

Quote: "They emit radiation for a long time before eventually opening up and allowing some information out."

But whom are they informing of this, and on what occasion? :)

[DrWeird]

8. I saw that.

Maybe if Hawking published something it might warrant a piece like this. But I can't help but thing it was just something he was rambling about, and not done any real work on.

14. 5 minute BBC interview with Hawking here

http://www.bbc.co.uk/newsa/n5ctrl/tvseq/newsnight/newsnight.ram
starting at 41:30 or dso.
He's serious about it. This recording of last night's programme may only be available for the next 15 minutes or os, till tonight's program starts (or maybe and hour and 15 minutes - they may wait until the nerw programmme finishes before replacing the old one).

[daleo]

20. I believe the "information" reference is getting at the notion of entropy

Increasing entropy implies increasing disorder and decreasing information. So, he seems to be saying that black hole processes do not always lead to increases in entropy. Or something like that.

I also remember studying Hawking radiation in a junior Astronomy course back in the late 1970's, so in this sense his speculations that black holes can emit radiation are not new. Although, I suppose he may have come up with a new angle.

That's about as far as my 20 year old B.Sc. will take me. For what it is worth, I once met Werner Israel, who worked with Hawking on black hole theory way back when ("black holes have no hair"). We didn't discuss cosmology, though. He just handed my some budget documents on university business. He seemed like a really nice, gentle soul, though.

12. Hawking had speculated that...

no information could escape a black hole (about what it contained). Apparently he has proven himself wrong...

[moof]

9. He said something about this in his book "a brief History of time"

He doesn'e go into any detail about it except to say that he thought he might have a different idea about black holes since his first
thinking on them.

11. Heisenberg's Uncertainty Principle?

It seems like I heard Stephen Hawking, John Wheeler, or someone mention a while back that HUP has a little "fine print" that may allow it to bleed away black holes little by little if they do not consume any matter or energy for some time.

Remember that the current popular theory of a black hole (string theory and M-theory notwithstanding) is that it's a zero-dimensional entity that nevertheless contains mass - in this case, the mass of an extremely heavy star that collapsed under its own gravity. The physical dimensions are gone, but the mass still remains. Now they're saying black holes may "secrete" this mass back into the universe if the conditions are right.

15. Bravo! This is how science works

OK, I have no horse in the fight over the nature of black holes, and I really know very little about cosmology besides the hard rock geology of the solar system's rocky bodies.

BUT, Hawkings is doing what every great scientist preaches, but what very few practice:

A great scientist SHOULD NOT be married to his or her pet theory, but instead advance the theory that the DATA is married to. When he wrote "A Brief History of Time," I am sure that the data supported the theory that black holes were non-emitting, but now, ~20 years later, there may be newer data suggesting that black holes aren't exactly like he characterised them, so now he's changed his theory to fit the data.

Again, this is exactly how science should work.

16. Saddening really, the reaction to this news on a progressive site

Blah MC Hawking BLAH Proven Himself Wrong! BWAH!!

Nobody yet knows what the real deal is, and like the existence of God for those that haven't experienced it, when one of the currently accepted great minds in science says "Wait a minute!" everyone jumps his shit and points towards satire. God forbid there's any real debate on the repercussions of his statements.

:eyes:

17. disgusting!

just another BHINO!

[hightime]

18. The DU is no place for a scientific discussion.

Aside from a few dozen posters, and you know who you are, the number of extremely well informed in narrow fields of study posters is quite small, whereas the number of people that will post on shit they know nothing about it enormous. The proof of this is the number of posts asking if global warming had a hand in the "forthcoming" magnetic field shift that was a topic about a week ago.

Of all the things I've ever lost, I miss my mind the most.

23. Every group of people will always have...

a generous supply of idiots, thats kind of inevitable.

(if you dont believe me, go to the Meeting Room aka "Astro Lounge")

22. At least he can admit when he's wrong...

Unlike alot of people I know.
