Description
In this lecture we will study the Schwarzschild spacetime, which represents a
nonrotating black hole in vacuum, from a variety of perspectives. After
considering the more intuitive coordinate chart representations of
Schwarzschild, we will then focus on Kruskal coordinates which is a global
coordinate chart on the whole spacetime. From this introductory material, we
will then transistion into a discussion about what the correct, or most
geometric, statement of the Penrose Conjecture for black holes should be.
Time permiting, we'll prove the Penrose Conjecture in a very special case,
discuss white holes as compared to black holes, and define a new notion of
horizon, called a generalized apparent horizon, which may be an important
notion useful for proving the Penrose Conjecture.
