3 Things You're Told About Light That Are WRONG | Leonard Susskind
#susskind #susskindinspired #LightDoesntMove

It sounds impossible… but what if light never actually moves? 🤯
We see light travel across the universe at 300,000 kilometers per second. Telescopes measure it. Physics calculates it. Yet relativity tells us something deeply counter intuitive: from light’s own perspective, nothing happens at all.

If motion requires time, and time does not pass for light… then what does motion even mean?

Inspired by ideas often associated with Leonard Susskind, this documentary-style exploration breaks down:

– Why light has no rest frame
– Why proper time for photons is zero
– Why emission and absorption are separated for us… but not for light
– How light defines causality and the structure of spacetime
– Why the speed of light is not just a speed — but a boundary of reality

No equations. No unnecessary jargon. Just clear intuition and powerful thought experiments. 🌌

By the end of this video, you may never think about motion the same way again.

If light does not experience time… then space and time themselves may not be as fundamental as we assume.

Watch till the end — the final section re frames everything.

If light does not experience time, does it even make sense to say it “travels”?

This video presents conceptual explanations based on modern relativity theory for educational purposes. Interpretations about the “perspective” of light are heuristic tools used to build intuition and should not be taken as literal physical frames of reference. Always refer to formal relativity theory for technical precision.
