Taking E=mc² as a staring point, could you please elucidate that statement?
please...
E=mc^2 has nothing to do with GENERAL relativity, which is the theory on which wormholes are based. In order to travel the distances of space you cannot go there without distorting the gravity field and moving space closer to you.
There is enough evidence to suggest there have been visitors to this planet before, so that means there must be ways to accomplish space travel.
You start by going downhill, with two guys pushing. Then you pop the clutch. Light speed is just over the next hill.
