So all energy/mater warps space-time, right? However, whenever we talk about the human manipulation of space-time it is a far-off goal requiring nothing short of tremendous amounts of energy and moving synthetic black holes around.
I don't know much about the mechanics of how space-time warps, but could the problem be addressed by focusing on density instead of unobtainable amounts of mass or energy?
Like although beyond anything currently available, isn't it true that for a laser of a finite energy if you were to focus it on a tremendously small point in space the local energy density would become sufficient to warp space time? Or perhaps a high enough energy particle collision? How do the mechanics work with "local super-dense concentrations of energy vs. a large voluminous body like a star? Just curios.
Also, for all of you really smart folk out there, someone give me something to hold on to that warp drive might be possible some day : )
