Hey,I have question bugging me for a couple of days now. I wanted to ask that according to Einstein's mass energy equivalence,if scientists create a warp drive allowing them to travel FTL(suppose at a speed 'c2' mentioned in formula E=mc2),which energy will they convert in while travelling at double the light speed or will they have safety measures to prevent the ship from turning into energy?Will they be stationary in the ship according to relativity?Will slowing down again turn them into matter i.e. mass?
