The Death Star.You know, the massive battle station from Star Wars. Its the size of a small moon. It would need some massive engines to get around. But half the thing is taken up by the laser and it doesn't have the glowing blue engines like every other ship in star wars. So how does it get around?
Since everybody else seems to just be mocking you, I'm going to be a non-conformist and actually try answering you.
I've always assumed it moved with a massive Ion engine, like what TIE fighters use, but much larger and much slower. All the Ion engines would ever need to do is provide enough propulsion to break an orbit. They could get around pretty easily and efficiently with a powerful (but VERY slow accelerating) Ion engine, gravity, and damn good calculus.
An Ion engine (A real thing btw) pulls tiny particles from open space and turns them into exhaust for propulsion, but this process is tremendously slow. My physics professor described it like this: Sit in a rolling chair *on an imaginary frictionless surface* and have someone slowly drop you paper clips. Once you have them, you flick the paper clips opposite the direction you want to move. enough tiny paper clips flicked and you'll be moving. In space you'll stay moving.
