Tachyons aren't a thing. Tachyons are sci-fi nonsense.
Nothing in the universe can travel faster than the speed of light. This does not hold for the universe itself. It can and does expand faster than the speed of light, using specific reference frames (i.e., big enough).
So, space can increase FTL. Particles do not travel faster than light tho, that is nonsense.
