Licht bewegt sich nicht. Die einfachste Erklärung, die es gibt.

Light doesn't move. Sounds crazy—but physics proves it. In this video, you'll get the simplest explanation there is: why light itself doesn't experience time or travel distance. No formulas. Just clear images, Feynman style. We'll build a light clock, chase light at 99.9% of the speed of light, land on GPS satellites in your pocket—and in the end, you'll understand why the fastest thing in the universe appears completely still from its own perspective. Why light doesn't move time or distance, but it doesn't travel time or distance, is it not the fastest thing in the universe?

The physical concepts presented (especially the photonic proper-time perspective) are didactic approximations based on the Feynman method. The statement "light does not move" refers to the mathematical description of the null geodesic in spacetime—strictly speaking, a photon does not possess a valid rest frame.
