^ I'm no expert, but there's no wind resistance and virtually no gravity in outer space (away from planets). These two factors, wind and gravity, are the things that keep things from moving.
So if you were to throw a tennis ball while in the blackness of space, it would just keep going and going and going. You can imagine a spacecraft doing the same thing, with the "throw" being just one (or several) thrust(s) of fuel to retain the momentum. The spacecraft could be capable of traveling at very fast speeds with little use of fossil fuels. I think that is why we saw the Endurance spacecraft just spinning through space with no kind of streaking flame behind it to suggest fuel use.
Space travel is MUCH more efficient than traveling on Earth, and the necessity for fossil fuels as energy can't be held to the same requirements.
If I'm wrong, someone please correct me, but I'll probably just ignore you anyway.
