Course Description

How did the universe begin? How did the fiery gases of the Big Bang collect into "island universes" like our own Milky Way, even as the universe as a whole was expanding into the frigid emptiness of today? What processes led to the formation of stars, planets, and life? Where do we go from here?

This course presents modern observations and theories of the structure and evolution of the universe. Topics include the evidence for the Big Bang, the formation of galaxies, and the nature of quasars. We trace the evolution of the universe from the first moment through the creation of the primeval fireball radiation and the birth and evolution of galaxies. We examine the rich variety of observations of quasars, the evidence for giant black holes, the accelerating universe, dark matter, and dark energy.

Mathematics will include high school algebra but no calculus.
