The inventor of the first anti-gravity engine, Dr. Jyte Gamerdinger said, “Time is the measurement of existence. History is the judgment of that existence.” Then he turned his engine on and knocked the earth off its axis by and inch. Luckily there was a fix, take the engine to the exact other side of the earth and turn it on again. Never mind the two cities ruined in the process, or the countless whales that beached themselves that year. Of course without this invention hitting the brakes at warp speed would be rather messy. I am not talking coffee on the dashboard messy, I am talking everyone in the starship being liquified when the hit they dashboard messy.
