Is Faster Than Light travel the wrong question?

If I remember correctly, it's taking an object the same amount of energy to move its mass through time at the speed of light while standing still as it would take to accelerate its mass through space. If time is simply another direction, then mass requires the same amount of energy, so to speak, no matter which direction or combination of directions in spacetime you're going.Or I could be remembering all this in the most confused way possible.
