Wait, he said that the faster you go the slower time goes for you *as seen by others*. So why would he say that from the photon's point of view time has stopped? Wouldn't be that time has stopped for the photon from an observer's point of view? In other words, the photon would perceive time to be passing at a normal rate, but it would perceive the universe to be frozen in space?

Fun fact. The german translation of "period" or "period of time" is "Zeitraum", which translated straight back means "timespace".
The meaning of this word in german goes a little further than "period" and comes a little closer to the meaning of the mathematical structure of space-time. This word subconsciously merges time and space.

Nice video. Philochrony is the theory that describes the nature of time and demonstrates its existence. Time is magnitive: objective, Imperceptible (intervals) and measurable.
