How do you prove tomorrow is future ? | Arrow of Time
What direction does time flow? This may seem like a strange question, yet it is one that has puzzled Philosophers throughout the ages.
If you watch a movie of a Newtonian system evolving, you would not normally notice if it plays in reverse or not. This makes it hard to know the direction of time. We address the issue in this video.
Big thanks to my long-time friend Alexandre Milewski, a PhD student at NYC, for the idea behind this video.
