    Like RJ was saying, because it moves through space rather than spacetime, and spacetime is an "all times at once" mathematical model of space and motion through it.

    The light cone is just an abstract thing. See what RJ said about light spheres.

    No. It moves through space all right. Then we model that using spacetime and worldlines and lightcones etc.
