think these monster black holes are spinning close to the limit set by

author and a visiting graduate student at Penn State University.</SPAN></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.livescience.com/space/scienceastronomy/080115-st-massive-black-hole.html"><P class="MsoNormal"><SPAN>Einstein's
