A Symposium on the Nature of Science

Fermilab's Wilson Hall
Saturday, March 18, 2000
8:15 AM to 4:00 PM


P. James E. Peebles

The evidence is that our universe has not always been the way it is now; it is expanding from a much hotter, denser state. The picture is far from complete, for we cannot say for sure why the universe is expanding, what it was doing before it was expanding, or how it all will end. I will present some astronomical pictures and other images that show what our universe is like, in the large-scale average, and illustrate the main pieces of evidence for its general expansion and cooling. I will also comment on some of the research aimed at filling in the details of the evolution of our universe.
