[quote:e1d9a]The inexorable one-way slide of the universe towards a heat death imprints on the world about us a distinctive "arrow of time", which serves to sharply differentiate past from future. The best way to think about this is to imagine a movie being played backwards. Chances are that it will look ridiculous and the audience will laugh. The deception is so obvious because most physical processes display a conspicuous directionality in time. The reverse process is either impossible or extremely improbable, spilt milk doesn't leap back into the jug and rivers don't flow uphill.
