I wish more people replied to me here >>12170084 because that's where I was going with this. I know black holes obviously have a shit load of mass and can send ripples in spacetime (I'm lucky enough to be 15 minutes away from one of the LIGO detectors so I hear a lot of talk about it)... but I have also considered the idea of a Kugelblitz- a black hole made of not mass but radiation, heat, etc. that acts the same as a black hole. Theoretically it creates an event horizon and warps spacetime as well. I just think this could offer some sort of way (even if it is just hypothetical) to utilize energy to warp spacetime without mass. And then of course you can try and think about unruh radiation and Rindler event horizons- but that's approaching quantum inertia which a lot of people look down on and laugh at. Either way I think the possibility of some sort of reactionless drive is within the realm of reality, we just haven't figured it out yet.
