Does the Universe Have a Beginning?

Friday, September 11, 2015, 5:00pm
Ungar Building Room 402


Does the universe have a beginning? The big bang theory predicts that it does and it happened 13.7 billion years ago. In this talk I will discuss the motivation for the big bang theory and its limitations to describing the universe. If the big bang theory isn't 100% accurate, then perhaps its prediction that the universe has a beginning is false. Although this question is still debated even today, a couple of theorems by Stephen Hawking and Roger Penrose show that in "physically reasonable" universes, there must be some sort of beginning. I will discuss the implications of these theorems and how they (only almost) answer the question of whether the universe had a beginning.
