What? Light doesn’t have speed, speed would imply some sort of relative movement that would require something like 3 spatial dimensions but even then everything would move at the same “speed” if you add up the dimensions the real question is why are you moving through space? And that gets into causality and a bunch of other God stuff you wouldn’t be interested in.

I think it’s a reference to light cones
The idea being that if you take relativity into account, everything is always moving “at the same speed”, it’s just something stationary is moving only in the time direction, and something moving in a spatial direction is therefore moving slightly slower in the time dimension.
I’ve heard this description before but I don’t think the math quite works out and it also doesn’t really explain why the speed of light is the speed limit.

Glad someone got it and the math works out I was watching something on it literally yesterday. Assuming I phrased everything correctly, it’s just the standard spacetime diagram rearranged.
