Recently, I've been watching a lot of those youtube videos debunking gyroscopic propulsion because everything about it violates the second law of motion or something........ This got me thinking, if I was floating in space and I decided to swing a large rock on a rope around me, to generate some centripetal force on the rock, then let go of the rope (it's a really long rope and I'm attached to the slack), I'm assuming it would just float away from me given the centripetal force. Now, since I'm attached to the rope, and given newton's second law, I would be able to pull my self a significant distance given the mass and velocity of the rock. Correct? Assuming this is correct, would something similar to this effect be possible on the quantum level with electrons and magnetic fields or something?
