"What Is Time?": don't try to find out by thinking you can reverse the past

Aperture explains “What Is Time?

The video connects “the arrow of time” with the idea in the universe entropy increases. 

Entropy relates to unpredictability. If you live in a 200 sq ft micro-apartment, you are more certain of the location of an object than if you live in a 5000 sq ft mansion.

The arrow of time also refers to irreversibility. If you’ve committed a crime, you can’t pretend it didn’t happen just to get out of jail.  At a quantum level, however, irreversibility may not hold because of entanglement.  You need a "Theory of Everything" to work all this out. 
Entropy may be the reason life must evolve.  Life tends to develop formats that can hold and execute conscious choices to change things.  Choices have irreversible consequences.
