Imagine that you could hop aboard a spaceship that traveled the speed of light. Well, you’ll have to imagine it, because it’s impossible—but that’s what imagination is for! So all aboard the Seeker 2000, bound for the outer edges of the universe. You can help by figuring out how far you’ll go and how long it will take to reach different places.
