ASTR422 : Cosmology (FALL 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 (in gross terms at least) the evolution of the Universe from a fraction of a second after the Big Bang up to the present time.   The Hot Big Bang gives us a framework in which to understand the creation of matter, the formation of the first elements, and the birth of cosmic structure (including galaxies and by extension stars, planets, and us).  This course outlines the Hot Big Bang theory, including the recent realization that the Universe is dominated by a mysterious “Dark Energy”.  It describes how a Universe of structure emerges from the smooth and featureless inferno of the early Universe, It ends with a discussion of the very early Universe and, in particular, the idea for explosion “inflation” in the first instances after the big bang.
