It feels obvious, almost trivial. Yet this simple fact hides one of the deepest mysteries in all of physics.
The past feels fixed.
The future feels open.
We feel regret about what already happened and hope about what’s still to come.
Time seems to flow in only one direction.
But here’s the mind-bending part: every fundamental law of physics works perfectly both forward and backward in time. Gravity doesn’t care. Electromagnetism doesn’t care. Even quantum mechanics doesn’t care. Run the equations backward, and they still work.
So why does the universe move only forward?
In this video—inspired by Richard Feynman’s legendary lecture “The Distinction of Past and Future”—we uncover the surprising answer. The arrow of time is not hidden in the laws of physics themselves. It’s hidden in probability.
The universe began in an extremely ordered state and has been gradually falling apart ever since. That growing disorder is called entropy. And entropy is what gives time its direction.
