What if everything you were taught about the speed of light is missing the deepest point?
We've all heard it — light travels at 300 million meters per second. The fastest thing in the universe. A cosmic speed limit. But Leonard Susskind argues that calling c a "speed" is not just incomplete — it's conceptually backwards. And once you understand what c actually is, everything about modern physics clicks into place in a way it never did before.
In this video, Susskind breaks down one of the most profound — and most under-explained — ideas in all of physics: c is not a speed. It's a conversion factor. A geometric exchange rate between space and time. And the moment that lands, time dilation stops being mysterious. E=mc² stops being a magic trick. The light speed limit stops being an arbitrary cosmic rule. It all becomes pure, inevitable geometry.
What you'll understand by the end of this video:
— Why space and time are not separate things, and what that actually means
— What c is really doing in the fabric of spacetime
— Why everything in the universe — including you, right now — moves through spacetime at exactly c
— Why a photon experiences zero time between emission and absorption
— Why E=mc² is really just E=m in disguise, and what the c² is actually hiding
— Why the speed of light is not the cause of spacetime geometry — it's the consequence of it
This is not a dumbed-down explainer. This is Susskind-style physics — building from first principles, using real geometry, treating you like someone who actually wants to understand the universe.
If you've ever felt like relativity was explained to you but never truly made sense, this is the video for you.
