A pair of physicists has reexamined the time it would take for information (think: your iPhone's memory) to potentially escape from inside a black hole.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciam.com/article.cfm?id=information-may-leak-from&sc=rss">
They find that the 1s and 0s of your address book could be recovered as quickly as 1,000 bits per second—far faster than previously expected. "The black hole really behaves like an information mirror," says physicist John Preskill of the California Institute of Technology in Pasadena.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciam.com/article.cfm?id=information-may-leak-from&sc=rss">
The finding, presented here at a meeting of the American Physical Society, marks the latest attempt to come to grips with the fate of information that has crossed the <A href="http://www.sciam.com/article.cfm?id=fiber-optic-event-horizon-mimics-black-hole">black hole event horizon</A>, a boundary beyond which even light cannot escape. There is no doubt, of course, that the ultradense <A href="http://www.sciam.com/podcast/episode.cfm?id=886EEF9E-E7F2-99DF-36619A7BE5D19F78">singularity</A> at the heart of a black hole would vaporize an iPhone. The question is whether there is any imaginable way to piece together its original state.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/D653BD7D-DF63-47E1-98A9-57AD048C6F2D/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
