Cosmic History and Time’s Arrow
I will begin by outlining what we know of the cosmological history of the universe.  I will discuss theories of the big bang - whether it was the “beginning” of time, or whether there were events that preceded it - and their implications for the ultimate fate of the universe.  Lastly, I will discuss the “arrow” of time - why there is a difference between past and future - and how this difference relates to cosmology.
