Astronomy has seen tremendous progress in the past century. Large telescopes on the ground and in space now give us views of the universe across the electromagnetic spectrum. Powerful computers can handle exponentially increasing volumes of data, and they allow simulations of remote objects and extreme astrophysics. We know how stars work, how many galaxies there are, and how to find exoplanets. Yet there is much we don’t know and areas where our physical understanding is weak. This course is a report from the frontiers of astronomy and physics research on five aspects of the universe where profound questions remain unanswered. The topics are the big bang, black holes, the Higgs particle, life beyond Earth, and the end of the universe.

Registration Opens Online: Monday, August 12, 2019 at 8AM (AZ Time)
