Someone on another forum I go to was talking about faster-than-light travel. According to him, takyons (which I understand most likely do not exist) would have the effect of "smoothing" the curvature of space-time. This would have the affect of speeding up travel. This seems a bit strange to me, and is not something I have heard anywhere else. I know takyons have imaginary mass based on the special relativity equations, but I do not have the mathematical background to apply the general relativity equations so there is no way for me to confirm his statements. A google search revealed nothing useful. I was wondering if someone could tell me whether his assertions regarding takyons are valid based on general relativity.
