>>21594835you don't understand the issue, it has nothing to do with the combined mass of the spacecraft. space and time are intrinsically linked, any change to one changes the other, and light speed is the maximum where the concept of space-time essentially breaks down like the motion-equivalent of a black hole.
light does not exist within space-time as we know it, it has no mass, it has no "time", neither concept exists for a photon. when light moves, from its perspective it's not even instantaneous travel, it's beyond that: the concept of travel isn't even a thing. for a photon going from point A to point B is essentially a one-dimensional state change. unfortunately for us, from our perspective it can only travel at light speed, and when something that doesn't even have the concept of travel still has a speed limit, that is a very aggressively firm speed limit. the only solution is some sort of hypothetical, non-traditional movement that allows you to reposition yourself without actually moving through space-time, like teleportation, wormholes, warp engines, etc.
