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://www.astro.ucla.edu/~wright/relatvty.htm an illustrated introductory guide to relativity Physics and Cosmology mattgundersen Mon, 27 Nov 2006 23:22:55 GMT http://www.muppetlabs.com/~breadbox/txt/al.html fjordaan Wed, 09 Mar 2005 23:13:48 GMT http://www.phy.syr.edu/research/relativity/RELATIVITY.html H-12 avrsarma Thu, 01 Jan 1970 00:00:00 GMT
