Friday, March 31, 8 p.m. Are we at the center of the universe? How did the universe begin, and how will it end? What existed before the Big Bang? Are there other universes? What is dark matter, and how does it affect our existence? Since antiquity, astronomers have continuously gained a greater understanding of our universe as they attempt to answer these types of questions. This program will focus on astronomical exploration methods to explain how we know what we know. A free STAR Observatory tour (weather dependent) follows at 9 p.m.
