Computers were slow, so they could only keep track of a few hundred or thousand stars, which limited the models severely. The software had to keep track of every star, its location, velocity, and mass… the number of calculations is forbidding.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://blogs.discovermagazine.com/badastronomy/2009/08/07/galaxy-smash/"><P>Things have come a long way. Now astronomers can track millions of stars using hydrodynamics codes, and then graphically display them giving them color, adding in dust, the effects of cloud collisions, supernovae… and the results are stunning. </P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://blogs.discovermagazine.com/badastronomy/2009/08/07/galaxy-smash/"><P><A target="_blank" href="http://www.youtube.com/watch?v=agqLEbOFT2A">Have a look</A>.
