Extra-terrestrial Life in the Milky Way Galaxy?
University of Texas at Austin
Are we alone? Along with questions about black holes, this is one of the questions most commonly asked of astrophysicists. While the simple answer is that we don’t know, logical and rational exploration of the question can be illuminating and a very good way to introduce non-scientists to the “scientific worldview.” This short essay is based on a class for students not majoring in science, which I have taught for nearly forty years at the University of Texas at Austin.
