Yeah um you don't really come out the other end of black holes, they are just massive balls of mass compressed so tightly that nothing escapes, not even light, maybe gamma ray burst at best... But you're not a gamma ray.

Theoretically enlarging a theoretical wormhole big enough to fit through is one possible way to travel into the future but not back but that is still not reaching a speed of light, that's kind of not got anything to do with speed.

Teleportation is another possible way but again that uses something like transference, forget what it's called but that isn't travelling at speed either, that is making a bunch atoms behave in the same way as another bunch so in teleportations you aren't travelling, you are being replicated exactly
