This is totally new to me, but very interesting. I really want to see the results of this project which proposes the reproduction of a black hole.

Hawking has said that "black holes are not really black after all: they glow like a hot body, and the smaller they are, the more they glow." Hawking's famous theory says that the temperature of a black hole varies inversely to its mass.</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.dailygalaxy.com/my_weblog/2009/08/are-black-holes-actually-white-dartmouth-team-looks-to-validate-stephen-hawkings-theory.html"><div align="center"><img src="http://content7.clipmarks.com/blog_cache/www.dailygalaxy.com/img/AD94B623-7EC7-4ED9-B80C-4DE3F84D84BF" alt="Stephen_hawking3" /></div></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.dailygalaxy.com/my_weblog/2009/08/are-black-holes-actually-white-dartmouth-team-looks-to-validate-stephen-hawkings-theory.html"><P>Meanwhile, up in Hanover, New Hampshire a bold team of researchers at Dartmouth College propose a new way of creating a reproduction black hole in the laboratory on a much-tinier scale than their celestial counterparts. The new method to create a tiny quantum sized black hole would allow researchers to better understand what physicist Stephen Hawking proposed more than 35 years ago: black holes are not totally void of activity; they emit photons, which is now known as Hawking radiation.</P></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/087DB0BF-57B1-4A34-BA3F-B4BFD641B259/blog/" title="blog or email this clip"><img src="http://content8.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>
