Hey everyone,
I've heard that with many mechanical devices that we place into space, we first loop them around the Earth to build up velocity, allowing for them to 'rocket' out of our gravitational pull and to gain some momentum. I've also heard that light curves around gravity; since light is a form of energy, I was wondering if energy is uniformly affected by gravity as well. If so, would it be possible to slingshot a minimal amount of energy around, say, a star, and to have it 'recharge' and return to it's point of origin? This is some really sci-fi stuff, I realize, but I'm just curious if it's at all feasible.
Thanks,
