Black Holes and the Extremes of Space, Time, and Gravity, taught by Dr. Cole Miller, Dept. of Astronomy is a broad overview of thought on space, time, and gravity, from the apparently commonsense musings of the ancient Greeks to our latest discoveries about the active role played by black holes in our universe. Throughout the course he will encourage discussion about the nature of scientific theories and the strength of evidence required to believe in the existence of apparently absurd objects such as black holes. He will conclude with an evaluation of the possible limits of advanced civilizations, including whether it is possible in principle to use wormholes and engage in time travel.
