I wouldn't say a new set of laws. Not until we have left the solar system.
I believe the closest we are to fast space travel would be the space drive. Once we are able to isolate and direct the graviton we will be well on our way. I also think this discovery will help us learn more about the fabric of the universe (support/refute Einstein's space-time theory), we will have reached the bottom rung of the hyperspace ladder.
The right man in the wrong place can make all the difference in the world.
