The End of Time

Some physicists went even further with this theory.

Julian Barbour, in his book The End of Time, argues that time doesn't exist as a basic feature of reality at all.

What exists, he says, is a vast, timeless set of possible configurations, and he calls them nows.

What we experience as time and motion is just the relationship between those static configurations held together by a mind that's capable of remembering more than one of them at once.

Carlo Rovelli, in his book The Order of Time, comes at it through the lens of quantum gravity and lands somewhere very related.

He says time isn't fundamental at the deepest level of reality.

It emerges approximately and statistically tied to entropy and tied to the particular limited vantage point each of us happens to have inside an enormously complicated universe.
