      What an excellent presentation, I would never have thought of entropy and dark energy in those ways. One doesn't often find these concepts distilled in such an understandable manor, great video. !

      It seems to me there are some important similarities between time and gravity. Both are unidirectional, both mysterious, both have mind bending properties. Perhaps there is no such thing as time. If there is only gravity. If you dispense with time completely, you just have gravity. Gravity is a vector field. The problem I am wrestling with, is mathematical, how does one take a derivative with respect to gravity?
