Document Summary

As requested, here is a list of the main topics we have covered since the second midterm. I"m sorry i wasn"t able to get this to you earlier. You should still be able to use it to ensure you fill in any holes in your studying thus far. * the types of galaxies: spiral, elliptical, and irregular. * the organization of galaxies into clusters and superclusters, tully-fisher. * methods for measuring distances in space: parallax, supernovae, variable stars. * how the different types of galaxies formed. * dark matter and dark energy; the evidence for the existence of both. * machos and wimps as dark matter candidates. * the contents of the universe as a whole (baryonic matter, dark matter, and dark energy) * the absoluteness of the speed of light. * special relativistic effects: time dilation, length contraction, and mass increase. * the curvature of spacetime as a replacement for newtonian gravity.
