Black Holes
This covers non-rotating black holes and the Schwarzschild metric. I will probably add Kerr (rotating) black holes when I feel like it.
Einstein's Equivalence Principle
This is a very rough derivation of the equivalence principle using basic princples of special relativity.
Warp Drives
This paper explores the concept of warp drives and how they can seemingly allow faster than light travel by exploiting the geometry of spacetime.
