Abstract

In this paper I would like to take a philosophical look at black holes. However, the issues I want to discuss do not concern just black holes themselves. I am not going to be concerned with such questions as whether black holes can or cannot exist, or what the proper way of characterizing them are. These questions, while fascinating, I take to be philosophically unproblematic. Since the pioneering work of Pen rose and Hawking it has been generally agreed that it is an unavoid able consequence of general relativity that black holes exist, and in a few cases there is observational (or astronomical) evidence for the existence of a black hole-the most prominent one being the X-ray source Cygnus X-l in the constellation Cygnus. Rather, I will be concerned with how black holes are connected with, and can shed light on, some familiar philosophical issues. Among these are whether the past and future are finite, the conceivability and possibility of time travel, and the intelligibility of the program of geometrodynamics.
