Atoms can flow very rapidly, pretty much unhindered, into this area of low density at speeds over four times the speed of sound.</p> <P>The result is a well into which all sound falls and cannot escape. Any sound that passes close enough to the "black hole" essentially ceases to be.</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/975370CF-A3DC-4A5D-9846-8867A6B9033D/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>
