- trhway 11y agoof course. We know that it is possible - the light speed is the limit of speed only in fixed metric space-time, and the Universe itself shows that non-fixed metric space-time(expansion/contraction) can produce FTL speed - just look at all those far galaxies running FTL away from us. It is just a "simple" matter of engineering of local space-time metric geometry changes :)
