Several years ago, scientists were attempting to measure how rapidly the expansion of the Universe was slowing down due to gravity pulling everything back together. New measurements, more accurate than any previously made, became available by using new techniques involving a peculiar type of exploding star — a type 1a supernovae. The scientific community was shocked to discover that the Universe is NOT slowing it’s expansion; the expansion rate is, in fact, speeding up. Professor Naftilan discusses the methodology that led to this result, possible theoretical explanations of the result (can you believe anti-gravity?), and the implications for the future of the Universe.
