The   intuitive notion that the universe has three
              dimensions    seems to be an irrefutable fact. After all,
              we can only move up or down, left or right, in or out.
    But are these three dimensions all we need to     describe nature?
    What if there aree, more dimensions         ? Would they necessarily
    affect us?  And if they didn't, how could we possibly know about
    them?  Some physicists and mathematicians investigating the
    beginning of the universe think they have some of the answers
    to these questions.  The universe, they argue, has far more than
    three, four, or five dimensions.  They believe it has eleven!</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.astronomycafe.net/cosm/dimens.html">
       Since the 1920s, physicists have tried numerous approaches
  to unifying the principal natural interactions: gravity,
  electromagnetism</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.astronomycafe.net/cosm/dimens.html">Unfortunately, physicists soon realized that general
  relativity in a four-dimensional space-time does not have enough
  mathematical "handles" on which to hang the frameworks for
  the other three forces.</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/49461BAC-45A7-4476-AD8A-62C158EB24CA/blog/" title="blog or email this clip"><img src="http://content7.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>
