For all of recorded history, and presumably well before that, people have been asking the Big Questions: What is the nature of the universe? How big is it? How old? What is our place in it?
For just as long, we've been making up answers. Every generation was convinced it got it right, and each in turn was proven wrong.
Stunning advances in modern cosmology finally appear to give definitive answers to some of the Big Questions. Professor McGaugh will explore the evidence supporting this picture, and ask whether we have finally got it right. History - and quite a lot of contradictory evidence - suggest we may still have a lot to learn.
About the Speaker:
Stacy McGaugh is a professor of astronomy at Case Western Reserve University in Cleveland, Ohio. His research interests include cosmology, dark matter, and the evolution of galaxies. He obtained a Ph.D. in Astronomy from the University of Michigan in 1992, working with professor G.D. Bothun. This year, McGaugh returns to Ann Arbor to give the annual Distinguished Alumnus Colloquium as well as a public lecture on the nature of the universe.
Each year a former University of Michigan graduate is invited to the Astronomy Department as a Distinguished Alumnus to present a Colloquium talk on their research and field questions.
