Mathematics and the Flow of Time

5/3/2014

We take for granted that there is a direction to the way things unfold in time. Eggs break but they don't unbreak; candles melt, but the don't unmelt . . These asymmetries govern our lives . .

But where does time’s asymmetry come from? What is responsible for this most basic of all time’s properties?

It turns out that the known and accepted laws of physics show no such asymmetry: each direction in time, forward and backward, is treated by the laws without distinction. And that’s the origin of a huge puzzle. Nothing in the equations of fundamental physics shows any sign of treating one direction in time differently from the other, and that is totally at odds with everything we experience.
