|You insist over and over again that it is impossible to go faster than the speed of light. This is completely and entirely untrue. Tachyons travel faster than light. They also go faster as they exert less and less energy. — K
I'm afraid that you confuse the hypothetical with the actual. While people have hypothesized about superluminal particles called tachyons, they have never been observed and probably don't exist. This speculation is based on an interesting but apparently non-physical class of solutions to the relativistic equations of motion. Although tachyons make for fun science fiction stories, they don't seem to have a place in the real world.
