If they’re able to produce negative energies of sufficient amplitude
Have we been able to produce any “negative energy” yet? I kind of got the impression that negative energy was some sort of mathematically valid alternate solution to some physics equation, but which didn’t have any basis in reality.
Not really. We can make tiny regions of relatively negative energy compared to empty space, but not in a way that does anything more useful than vacuum-welding metals together and there is disagreement as to how far much further down the zero point is.
