Abstract

The study of astronomy greatly accelerated in the twentieth century. Aided by many advances in technology that improved observations, there has been an explosion of information about the cosmos, and scientists have had to review and overturn many long-held beliefs and assumptions about the universe. Among the most perplexing and enduring questions has been the nature of a mysterious substance known as dark matter.
