This is about traveling faster than light and hyperspace.
In an answer to something that was said earlier, yeah E=MC^2. So that way is not the way to go. But traveling through a different dimension would be possible. In Halo they use a system of faster than light travel that involves the opening of a hole into a thing that they called subspace. This subspace would be another dimension and there for could have a different set of laws WHEN APPLIED TO TRAVELING. In this case Subspace would be like hyperspace and for every light-minute in the sub dimension you could have traveled a light-year. But what i'm trying to say is that faster than light travel here my not be possible but going to a different dimension and going to faster than light may be possible. (Oh and I'm just a High school student, so please dont slam me if my idea is wrong)
