High entropy, the opposite.
This is why you know your past but not your future.

My friends were talking about someone who could see the future and none of us believed it so were joking around the subject.
One of my friends said "I have a very similar skill to the man who can see the future."

"Ha Ha! Very good!" we laughed.
Some skill indeed! We can see what could never have been different.
