Travel at faster than light speed is possible in the world, by accessing Einstein-Rosen Bridges, folding space-time to get across the universe faster. The most common way of accessing these wormholes is by using a Bridge Drive connected to the engine of a spacecraft. This is the most common way, but still very rare in the grand scheme of things. Theoretically, Zero could access his powers to perform quantum travel, but the skill needed to do so would be intensive.
