<DIV>All thanks, Joel. I seized on this one, too.</DIV>
<DIV> </DIV>
<DIV>The insight--that black holes DO allow information to escape, seemed intuitively obvious, perhaps because in big bang theory this entire cosmos leaked into existence from the equivalent of a black hole--a singularity.</DIV>
<DIV> </DIV>
<DIV>If I understand what Hawking's getting at, and there's a chance that I may not, his notion gives credence to one of my bizarre speculations--that whatever information this cosmos gathers in its lifetime, it will be able to pass on to the universe on the other side of the big crunch in which the cosmos will end. </DIV>
<DIV> </DIV>
<DIV>In other words, universes, I suspect, can gather a store of networked information and, if they have clever beings with will and hubris, can compress that information and pass it on to their progeny. J</DIV>
<DIV> </DIV>
<DIV>ust as we living beings pass information on through genes or through memes, the cosmos that produces willfull, living beings can take their primitive capacities a long way in 20 billion years or so.</DIV>
<DIV> </DIV>
<DIV>That 20 billion year figure, by the way, is based on my guess that this cosmos will survive for a total span of 30 billion years from birth to destruction. Others better qualified than I am--Max Tegmark for example, who has a toroidal theory like mine-- put the total lifespan of the universe in the trillions of years. Onward--Howard</DIV>

<BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"><FONT face=Arial><BR>The about-turn might cost Hawking, a physicist at the University of <BR>Cambridge, an encyclopaedia because of a bet he made in 1997. More <BR>importantly, it might solve one of the long-standing puzzles in modern <BR>physics, known as the black hole information paradox.<BR><BR>It was Hawking's own work that created the paradox. In 1976, he calculated <BR>that once a black hole forms, it starts losing mass by radiating energy. <BR>This "Hawking radiation" contains no information about the matter inside the <BR>black hole and once the black hole evaporates, all information is lost.<BR><BR>But this conflicts with the laws of quantum physics, which say that such <BR>information can never be completely wiped out. Hawking's argument was that <BR>the intense gravitational fields of black holes somehow unravel the laws of <BR>quantum physics.<BR><BR>Other physicists have tried to chip away at this paradox. Earlier in 2004, <BR>Samir Mathur of Ohio State University in Columbus and his colleagues showed <BR>that if a black hole is modelled according to string theory - in which the <BR>universe is made of tiny, vibrating strings rather than point-like particles <BR>- then the black hole becomes a giant tangle of strings. And the Hawking <BR>radiation emitted by this "fuzzball" does contain information about the <BR>insides of a black hole (New Scientist print edition, 13 March).<BR><BR><BR>Big reputation<BR><BR><BR>Now, it seems that Hawking too has an answer to the conundrum and the <BR>physics community is abuzz with the news. Hawking requested at the last <BR>minute that he be allowed to present his findings at the 17th International <BR>Conference on General Relativity and Gravitation in Dublin, Ireland.<BR><BR>"He sent a note saying 'I have solved the black hole information paradox and <BR>I want to talk about it'," says Curt Cutler, a physicist at the Albert <BR>Einstein Institute in Golm, Germany, who is chairing the conference's <BR>scientific committee. "I haven't seen a preprint [of the paper]. To be quite <BR>honest, I went on Hawking's reputation."<BR><BR>Though Hawking has not yet revealed the detailed maths behind his finding, <BR>sketchy details have emerged from a seminar Hawking gave at Cambridge. <BR>According to Cambridge colleague Gary Gibbons, an expert on the physics of <BR>black holes who was at the seminar, Hawking's black holes, unlike classic <BR>black holes, do not have a well-defined event horizon that hides everything <BR>within them from the outside world.<BR><BR>In essence, his new black holes now never quite become the kind that gobble <BR>up everything. Instead, they keep emitting radiation for a long time, and <BR>eventually open up to reveal the information within. "It's possible that <BR>what he presented in the seminar is a solution," says Gibbons. "But I think <BR>you have to say the jury is still out."<BR><BR><BR>Forever hidden<BR><BR><BR>At the conference, Hawking will have an hour on 21 July to make his case. If <BR>he succeeds, then, ironically, he will lose a bet that he and theoretical <BR>physicist Kip Thorne of the California Institute of Technology (Caltech) in <BR>Pasadena made with John Preskill, also of Caltech.<BR><BR>They argued that "information swallowed by a black hole is forever hidden, <BR>and can never be revealed".<BR><BR>"Since Stephen has changed his view and now believes that black holes do not <BR>destroy information, I expect him [and Kip] to concede the bet," Preskill <BR>told New Scientist. The duo are expected to present Preskill with an <BR>encyclopaedia of his choice "from which information can be recovered at <BR>will".<BR><BR><BR>Jenny Hogan</FONT></BLOCKQUOTE>
