Through normal sublight travel? Impossible. Its near impossible to even travel at light speed because as your speed approaches light speed, the amount of energy needed to go faster increases infinitely.

There a few theoretical ways to do so, one of which is wormholes, but the problem is that it takes an inmense amount of energy to create one and the ones that are created are like on the subatomic scale and collapse in life a second(possibly due to dark matter?0
