I recently read Sean Carroll’s ‘From Eternity To Here’ and I thought it was a superb explanation of the physics that might lead us to understanding time. But don’t be fooled into thinking it has the answer to “what is time?”, we still don’t have a full understanding, fortunately we do however have General Relativity, Quantum Field Theory, Entropy, and a bunch of other cool theories that Professor Carroll ties together very clearly. It’s very light on math also, in case you happen to have that phobia.
‘From Eternity To Here’ also includes bits of interesting history of how we have perceived and explained time and cool stories of the physicists and their discoveries.
Enjoy!
