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
