why does time flow in one direction and not the other? why do we remember the past and not the future? how did our early universe have so many particles packed so tightly together in such a small volume? what initiated the burst of inflation very early in the existence of our universe? why/how was entropy lower in the early universe than it is now?
sean carroll at cosmic variance attempts to explain his understanding of the universe in terms we can all begin to discuss. he examines the arrow of time and other interesting topics in a way that makes your brain twist trying to understand how they all fit together! enjoy!
