Title: A Grand Tour of the Universe

Abstract: Astronomy is unlike other sciences in that there are no experiments we can perform or expeditions we can mount. We are reduced to passively observing the light the Universe sends us, some of which has traveled billions of years before falling on our telescopes. In this light, however, we can read the life cycles of stars and recount the entire history of the cosmos. Replete with colliding galaxies and a fly-through of the Universe set to the Blue Danube waltz, this lecture provides one-stop shopping for a comprehensive tour of all of space and time.
