Course Description

With recent advances in physics (and philosophy), we are finally able to make some headway into some of the most pressing questions of the universe. We will explore such topics as the big bang theory, time travel, relativity, extraterrestrial life, and string theory. We will attempt to answer some big questions such as: Was there a beginning of time? Will there be an end? Is time travel possible?
