Μεταφορτώθηκε στις 29 Σεπ 2008
Frontiers/Controversies in Astrophysics (ASTR 160)
Class
begins with a review of the mysterious nature of dark matter, which
accounts for three quarters of the universe. Different models of the
universe are graphed. The nature, frequency, and duration of supernovae
are then addressed. Professor Bailyn presents data from the Supernova
Cosmology Project and pictures of supernovae taken by the Hubble Space
Telescope. The discovery of dark energy is revisited and the density of
dark energy is calculated. The Big Rip is presented as an alternative
hypothesis for the fate of the universe.
00:00 - Chapter 1. Review of Dark Matter
04:51 - Chapter 2. Supernovae
20:53 - Chapter 3. Finding Supernovae: The Supernovae Cosmology Project
34:41 - Chapter 4. The Constant Density of Dark Matter and the Big Rip
