Course Objectives

This course provides an introduction into our basic understanding of the formation, structure, and evolution of the universe. Where do the light and the matter permeating space come from? What do we really mean when we say that "the universe is expanding"? How do we know that it was hot and dense at the beginning? What was the Big Bang, and what are the residual traces of this event? How did the intricate cosmic structure, evident in vast astronomical surveys, come into existence? Why are there billions upon billions of stars in every galaxy, and billions of galaxies in the observable universe? What are black holes and what is their unique role in the transformation of galaxies? Where are the boundaries of the present understanding? What are the missing pieces, and what are the scientists doing to complete the picture? Along with a review of modern cosmology, I will discuss the historical emergence of the discipline from its pre-scientific precursors. While tracing the evolution of the universe to its beginnings, I will review recent and future experiments and missions, conducted on Earth and in space, to explore and measure the universe. I will use these examples to illustrate the mechanisms of scientific discovery that set science apart from other endeavors.
