I just watched this and found the ending quite comforting: at the end, entropy stops increasing and nothing happens, forever. After a long week at work, it's pretty much what I'm up for!
It means nothing to my life, but the thought that it all ends in cold dark silence is very depressing. Hopefully we've got the science on dark energy wrong and a big crunch provides the possibility of re-birth.
A trillions of years long work week would leave anyone tired!
