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?

why do i exist at all :DD

Hum, I think I see an inconsistency here. Imagine if you will, if the universe started with a big bang,(no problem here), however imagine it from the vantage point of quantum entanglement and mechanics. If from this one particle everything comes into existence, then normal physical measurements do not apply! Thus time and distance are irrelevant and the existence and light from those stars reached us instantaneously. Since we know there is an infinite exist of galaxies within an infinite sized universe, their number can not be explained by an application of finite thermal dynamics and general science. Sorry guys it doesn't fit, literally. :wink:

Two universal "edges",(in a multiverse) "touch" each other. The reaction forms a new universe. Or, the matter sucked into a black hole pops out of a "white" hole in another universe.?...
