In this universe there is no such thing as “faster-than-light” travel. The speed of light is not only a good idea, it’s the law. You can’t get to it; the closer you accelerate toward it, the more energy you need to keep going toward, and it’s a horrible idea to go that fast anyway, since space is only mostly empty, and anything you collide with at an appreciable percentage of the speed of light is going to turn your fragile spaceship into explody chunks of metal.
