Even if the galaxy reached its civilizational peak more than 5 billion years ago, most of the civilizations that were around then have likely self-annihilated, the researchers found. This last bit is the most uncertain variable in the paper; how often do civilizations kill themselves? But it's also the most important in determining how widespread civilization is, the researchers found. Even an extraordinarily low chance of a given civilization wiping itself out in any given century — say, via nuclear holocaust or runaway climate change — would mean that the overwhelming majority of peak Milky Way civilizations are already gone]]> extraterrestrials space astronomy https://pinboard.in/ https://pinboard.in/u:matthewmcvickar/b:0923fea8e294/ 2011-02-25T02:06:12+00:00 http://www.howmanypeopleareinspacerightnow.com/ matthewmcvickar space astronomy history science https://pinboard.in/ https://pinboard.in/u:matthewmcvickar/b:6de379f10c92/ 2008-12-07T20:00:46+00:00 http://www.boston.com/bigpicture/2008/12/hubble_space_telescope_advent.html matthewmcvickar space images christmas calendar astronomy science photography telescope nasa hubble https://pinboard.in/u:matthewmcvickar/b:d793dba9bf24/ 2008-10-21T23:20:27+00:00 http://flickr.com/photos/smithsonian/sets/72157608016866848/ matthewmcvickar space astronomy photography science universe telescope https://pinboard.in/u:matthewmcvickar/b:be96b9d3b128/ 2008-08-08T01:22:21+00:00 http://whatyouseewhenyoudie.ytmnd.com/ matthewmcvickar ytmnd humor weird lolcats space https://pinboard.in/u:matthewmcvickar/b:1ed693f05ee7/ 2008-07-29T06:04:42+00:00 http://blogs.discovermagazine.com/badastronomy/2008/07/17/holy-frak-moon-transits-earth/ matthewmcvickar video space science earth moon astronomy https://pinboard.in/u:matthewmcvickar/b:c0f3bc625b1c/ 2008-05-08T12:00:09+00:00 http://interconnected.org/home/more/lightcone/ matthewmcvickar space science self rss physics fun https://pinboard.in/u:matthewmcvickar/b:35aaa9480917/ 2006-12-18T04:14:52+00:00 http://www.spacetelescope.org/images/archive/top100/ matthewmcvickar space technology photography NASA https://pinboard.in/u:matthewmcvickar/b:8925e1546d12/ 2006-10-07T20:28:19+00:00 http://faculty.washington.edu/jcramer/BBSound.html matthewmcvickar bigbang science space sound https://pinboard.in/u:matthewmcvickar/b:02adfbbd3c13/ 2005-06-20T03:47:17+00:00 http://science.nasa.gov/headlines/y2005/20jun_moonillusion.htm matthewmcvickar nature space https://pinboard.in/u:matthewmcvickar/b:e05e8e7adac1/ 2005-04-01T15:29:29+00:00 http://antwrp.gsfc.nasa.gov/apod/ap050401.html matthewmcvickar humor science space https://pinboard.in/u:matthewmcvickar/b:6220748b9150/ 2005-01-26T13:48:24+00:00 http://www.msnbc.msn.com/id/6867061/ matthewmcvickar science people space writing https://pinboard.in/u:matthewmcvickar/b:993131212513/ 2004-12-20T17:08:58+00:00 http://antwrp.gsfc.nasa.gov/apod/ap041220.html matthewmcvickar science space technology https://pinboard.in/u:matthewmcvickar/b:8f657fe04743/ 2004-10-31T17:18:53+00:00 http://antwrp.gsfc.nasa.gov/apod/ap030510.html matthewmcvickar science space https://pinboard.in/u:matthewmcvickar/b:5790007b4c1e/ 2004-10-31T17:15:09+00:00 http://antwrp.gsfc.nasa.gov/apod/ap041029.html matthewmcvickar science space https://pinboard.in/u:matthewmcvickar/b:7380bcb4e04e/ 2004-10-04T17:41:06+00:00 http://www.cnn.com/2004/TECH/space/10/04/spaceshipone.attempt.cnn/index.html matthewmcvickar science technology space https://pinboard.in/u:matthewmcvickar/b:aa5a4d62e7fd/ 2004-07-18T23:07:24+00:00 http://www.newscientist.com/news/news.jsp?id=ns99996151 matthewmcvickar people science space https://pinboard.in/u:matthewmcvickar/b:21b1f81857c5/
