But according to Richard Feynman and the laws of physics, that intuition is deeply misleading.

At the fundamental level, the equations that describe reality don’t care which way time flows. The same mathematics behind Quantum Electrodynamics — the most precisely tested theory in science — work just as well forward in time as they do backward.

In this video, we explore why the past may not be as “gone” as it feels.

🎥 *In this video, we explore:*
→ Why the laws of physics don’t distinguish past from future
→ How particles can be treated as moving backward in time in calculations
→ What time symmetry really means — and what it doesn’t
→ Why our experience of time is not fundamental
→ How Feynman explained time without mysticism.

This isn’t philosophy or speculation.
This is how physicists actually calculate the universe.
