In order to understand how the Universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent Universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed. pdboyer Sat, 06 Nov 2010 19:37:04 GMT http://science.nasa.gov/big-questions/ Big Questions NASA has defined a set of space and Earth Science questions that can best be addressed using the Agency’s unique capabilities.  NASA works with the broader scientific community, considers national initiatives, and the results of decade-long surveys by the National Research Council in defining these questions. See also the Science Strategy section for more information about how NASA Science is pursuing these questions. pdboyer Sat, 06 Nov 2010 19:33:35 GMT http://www.sas.upenn.edu/home/news/troddenandabbate/trodden.html Research summary of old notions of the expanding universe and newer approach to explain how galaxies can to continue moving away from each other at ever-increasing velocities. Talks about Einstein's general theory of relativity -- movement being a curvature of space/time continuum (or something like this) pdboyer Sat, 06 Nov 2010 00:14:19 GMT http://cas.sdss.org/dr5/en/proj/teachers/advanced/hubble/specifics.asp Teacher's Guide to Specific Sections Introduction Let students read through the Introduction on their own. Ask them why the discovery that the universe was expanding was so unexpected. Point out that its discovery required three separate threads to come together: Einstein's General Relativity, Slipher's measurements of redshifts, and the building of the new 100" telescope on Mount Wilson. Ask them how the three other lines of evidence support the big bang theory. Get them thinking about how different lines of evidence add up to support a scientific theory. Ask: what makes a good theory? pdboyer Sat, 24 Apr 2010 16:02:46 GMT http://en.wikipedia.org/wiki/Albert_Einstein Wikipedia, the free encyclopedia cosmology Eddie Tue, 30 Mar 2010 15:23:54 GMT http://www.ucolick.org/~diemand/vl/ high resolution Milky Way dark matter halos Zigtag Imported Bookmarks johnrod Mon, 11 Aug 2008 01:23:58 GMT http://www.cosmologyathome.org/ this might be something fun to do from home markdykeman Fri, 26 Oct 2007 14:39:22 GMT http://www.pbs.org/wgbh/nova/universe/howbig.html markdykeman Mon, 01 Oct 2007 00:22:34 GMT http://www.alberteinstein.info/ Physics and Cosmology mattgundersen Wed, 04 Jul 2007 23:07:00 GMT http://galileo.phys.virginia.edu/classes/109N/lectures/lecturelist.html Lecture Index Physics and Cosmology mattgundersen Tue, 19 Jun 2007 03:57:53 GMT
