Beginning with the publication of Albert Einstein's theory of relativity, through the wild revolution of quantum mechanics, and up until the physics of the modern day (including the astonishing revelation, in 1998, that the Universe is not only expanding, but doing so at an ever-quickening pace), much of what physicists have seen in our Universe suggests that much of our Universe is unseen&#8212;that we live in a dark cosmos. </p> <p> Everyone knows that there are things no one can see&#8212;the air you're breathing, for example, or, to be more exotic, a black hole. But what everyone does not know is that what we can see&#8212;a book, a cat, or our planet&#8212;makes up only 5 percent of the Universe. The rest&#8212;fully 95 percent&#8212;is totally invisible to us; its presence discernible only by the weak effects it has on visible matter around it. </p> <p> This invisible stuff comes in two varieties&#8212;dark matter and dark energy. One holds the Universe together, while the other tears it apart. What these forces really are has been a mystery for as long as anyone has suspected they were there, but the latest discoveries of experimental physics have brought us closer to that knowledge. Particle physicist Dan Hooper takes his readers, with wit, grace, and a keen knack for explaining the toughest ideas science has to offer, on a quest few would have ever expected: to discover what makes up our dark cosmos. </p> 167774 2006 Dark Cosmos: In Search of Our Universe's Missing Mass and Energy total:15|5:2|4:6|3:6|2:1| 15 54 40 3 3 0 false false Tue Jul 21 00:00:00 -0700 2009 Thu Jul 16 11:44:19 -0700 2009 Tue Jul 21 11:38:16 -0700 2009 1 more...]]> 3 0 false false Sat May 02 00:00:00 -0700 2009 Mon Jan 07 12:24:05 -0800 2008 Sat May 02 23:54:18 -0700 2009 more...]]> 3 0 false false Sun Mar 01 00:00:00 -0800 2009 Sat Mar 01 06:51:17 -0800 2008 Wed Mar 25 23:39:02 -0700 2009 0 0 false false Fri Nov 27 09:23:30 -0800 2009 Fri Nov 27 09:23:30 -0800 2009 0 0 false false Fri Oct 16 17:47:09 -0700 2009 Fri Oct 16 17:47:09 -0700 2009 0 0 false false Mon Aug 24 19:52:59 -0700 2009 Mon Aug 24 19:52:59 -0700 2009 4 0 false false Wed Aug 26 13:18:08 -0700 2009 Sat Aug 22 12:34:50 -0700 2009 Wed Aug 26 13:18:08 -0700 2009 0 0 false false Mon Jul 13 23:11:45 -0700 2009 Mon Jul 13 23:11:45 -0700 2009 0 0 false false Tue Jun 09 13:54:49 -0700 2009 Tue Jun 09 13:54:49 -0700 2009 0 0 false false Sat May 23 16:46:46 -0700 2009 Sat May 23 16:46:46 -0700 2009 4 0 false false Wed Apr 22 12:25:10 -0700 2009 Wed Apr 22 12:25:10 -0700 2009 0 0 false false Sun Mar 29 22:41:20 -0700 2009 Sun Mar 29 22:41:20 -0700 2009 5 0 false false Fri May 15 19:09:33 -0700 2009 Sat Feb 21 18:07:00 -0800 2009 Fri May 15 19:09:33 -0700 2009 0 0 false false Thu Jan 08 22:17:34 -0800 2009 Thu Jan 08 22:17:42 -0800 2009 4 0 false false Sat Jan 03 10:32:34 -0800 2009 Sat Jan 03 10:32:34 -0800 2009 0 0 false false Sun Oct 19 23:56:10 -0700 2008 Sun Oct 19 23:56:10 -0700 2008 0 0 false false Wed Oct 08 18:31:34 -0700 2008 Wed Oct 08 18:31:34 -0700 2008 0 0 false false Wed Sep 17 00:11:14 -0700 2008 Wed Sep 17 00:11:14 -0700 2008 0 0 false false Thu Aug 21 12:44:00 -0700 2008 Thu Aug 21 12:44:00 -0700 2008 0 0 false false Thu Aug 07 07:48:10 -0700 2008 Thu Aug 07 07:48:10 -0700 2008 http://www.goodreads.com/book_link/follow/8?book_id=173694
