Tormod Posted July 15, 2004 Report Share Posted July 15, 2004 This is rather controversial: Hawking cracks black hole paradoxAfter nearly 30 years of arguing that a black hole destroys everything that falls into it, Stephen Hawking is saying he was wrong. It seems that black holes may after all allow information within them to escape. Hawking will present his latest finding at a conference in Ireland next week.

I wonder what this will do to cosmology - the riddle of black holes may perhaps be simpler than we imagine. Tormod Link to comment Share on other sites More sharing options...
GAHD Posted July 15, 2004 Report Share Posted July 15, 2004 Now THAT I gotta see! Too bad I can't read the article Sorry!

Now they have to maintain the information minus the mass. Link to comment Share on other sites More sharing options...
Uncle Martin Posted July 16, 2004 Report Share Posted July 16, 2004 Black hole is such a misleading name, even worse than "the big bang". I like Dark Massive Gravitating Body.. much better. Fewer would be so confused about their characteristics if not for the headline grabbing names. Then I also suppose that the average guy would not have heard of them either.

Bo Posted July 16, 2004 Report Share Posted July 16, 2004 Well i cant find the article, but it sounds quite interesting. This has something to do with the entropy of a black hole or so? btw in the 80s or so it was already proven (also by hawking) that a black body does sends out some radiation, because of quantum fluctuations at the schwarzschild radius (the 'point of no return') Bo Link to comment Share on other sites More sharing options...

This has something to do with the entropy of a black hole or so?Perhaps "entropy" because it is about "information", or conservation there of. But related more to information connected to the mass attracked into the black hole. From the site: "After nearly 30 years of arguing that a black hole destroys everything that falls into it, Stephen Hawking is saying he was wrong. It seems that black holes may after all allow information within them to escape....It was Hawking's own work that created the paradox. In 1976, he calculated that once a black hole forms, it starts losing mass by radiating energy. This "Hawking radiation" contains no information about the matter inside the black hole and once the black hole evaporates, all information is lost. But this conflicts with the laws of quantum physics, which say that such information can never be completely wiped out. Hawking's argument was that the intense gravitational fields of black holes somehow unravel the laws of quantum physics..." Link to comment Share on other sites More sharing options...
Freethinker Posted July 16, 2004 Report Share Posted July 16, 2004 I tested the link after the post and it seems to work. (Added in Edit) Strange that the visual part (URL's) of the two links, Tormod's original and my new one, are identical. Yet when I use Tormods it fails and mine works, for me anyway. Perhaps something to do with the parsing of this Hypo's scripting? (Added in additional Edit) I have been trying to find the problem. I compared Tormod's post and mine by using "Quote" to see the underlying code for each. Mone keeps the link's URL correct while Tormod's adds various things. e.g if you do a "Copy Link" for each you get this from Tormods: (http:// removed to stop parser from messing it up) http://www.newscientist.com/news/news.jsp?id=ns99996151%3CBR%3E while mine shows: http://www.newscientist.com/news/news.jsp?id=ns99996151 I tried to edit Tormod's post (only to correct the URL problem) and it keeps dumping extra characters into the URL no matter what I try.
