In that case, given the linear geometry of photonic world lines, ${(x^i-x^i_0)\over (x^4-x^4_0}=v_i$can be understood as a slope of line formula, which can be transposed to the relation you seek. Where of course, the photon paths have been parametrized as unit speed curves. | |

| Dec 18, 2023 at 21:28 | comment | added | Solomon Slow | If an event is on your world line, that means the event happens to you. If it merely is near your world line, then the event happens near you. If your world line intersects the world line of a photon, that means that the photon hit you (and, probably also means that the photon's world line terminates at the point where it intersects yours.) | |
