Grandfather paradox. Traveling into the future is possible because the faster you travel the slower time passes for you. In fact at the speed of light time stops, so when a photon is created (from its perspective) it isntantly hits whatever is in its way. FTL systems wouldn't have to have infinate energy if this was true then quasars would be flying around the universe faster than light. You need a massive amount of energy and a way to bend space-time.
