Why Light Has No Speed Through Spacetime — Einstein's Hidden Answer

Why does light have no speed through spacetime — none at all, once you look at the geometry properly? This film traces the real physics behind one of relativity's strangest, most misunderstood conclusions, from the null result of the Michelson-Morley experiment in 1887, through Einstein's 1905 postulates, to Minkowski's 1908 reformulation of space and time into a single four-dimensional structure. Every experiment cited is real, dated, and published. No invented science, no pseudoscience, no filler analogies standing in for the actual mechanism — just the documented history of how physicists discovered light's true relationship to time, and what it means for the clock you're carrying right now.

Reason to Watch Most explanations of relativity stop at "time slows down" and never explain why light itself sits completely outside that rule. This film walks through the actual experiments and actual papers that forced physicists to accept it, with no hand-wavy analogies standing in for the real mechanism. If you've ever wondered what a beam of light "experiences" on its way to your eye, this is the sourced, unembellished answer.
