    This reads like a “do your own research” type of person commented it.

      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.
