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
* The cosmic distance ladder
* Methods for measuring distances in space: parallax, supernovae, variable stars
* Hubble's Law
* The expansion of space
* The cosmological principle
* Cosmological redshifts
* Galaxy evolution
* How we observe galaxy evolution
* Galaxy formation
* How the different types of galaxies formed
* Galaxy mergers
* Quasars
* Active galactic nuclei
* Starburst galaxies
* Supermassive black holes
* The Galactic center
* The Lyman alpha forest
* Dark matter and dark energy; the evidence for the existence of both
* Galaxy rotation curves
* Gravitational lensing
* MACHOs and WIMPs as dark matter candidates
* The fate of the universe
* The contents of the universe as a whole (baryonic matter, dark matter, and dark energy)
* The relativity of motion
* The absoluteness of the speed of light
* Special relativistic effects: time dilation, length contraction, and mass increase
* The twin paradox
* The concept of 'spacetime'
* The equivalence principle and general relativity
* The curvature of spacetime as a replacement for Newtonian gravity
* The basics of the Big Bang model--what does it say and what doesn't it say?
* The evidence for the BBM: Hubble's Law, the cosmic microwave background, and nucleosynthesis
* Problems with the BBM
* Inflation as a solution to some BBM problems
