Cosmology is the science of beginnings and endings. Cosmologists tend to concentrate on the first three milliseconds, or the first three seconds, or at most the first three years of history; and on the last few eons as well. It was not always this way. In olden days scientists tended to believe in a static universe. But 60 years ago the world learned that the universe is not static, and then the questions "Where did we come from?" and "Where are we going?" became scientific questions. When these questions are mixed with modern theories of general relativity and quantum mechanics -- as seemed appropriate at the recent Third Loyola Conference on Quantum Theory and Gravitation, held at Loyola University in New Orleans--some interesting ideas result.
