ASTR622 : Cosmology (Spring 2016; REYNOLDS)

 

COURSE DESCRIPTION

The Hot Big Bang Theory is one of the most remarkable successes of modern science.  Within the framework of this theory, we can understand (at least in gross terms) the evolution of the Universe from a fraction of a second after the Big Bang through to the present time.  The Hot Big Bang Theory gives us the framework in which to understand the creation of matter, the formation of the first elements, and the birth of cosmic structure (including galaxies, stars, planets and us!).  This course outlines the Hot Big Bang Theory.
