...and so, to summarise, that's why travel to the future through a wormhole is impossible, and the amount of energy needed to sustain a wormhole big enough for us to fit, would be more than all the suns of our galaxy combined. Remember, taking motion into consideration, the full version of Einstein's mass-energy equivalence equation is
E^2 = (mc^2 )^2 + (pc)^2 whre p equals
