Ok, doesn't seem enough power there to move planets, but a guy demonstrated how pulling mass in increases the spin speed, but still don't see how was the dust spinning at the start? Maybe I'll stick to Electro-Magnetism!
I wrote this before seeing the previous answer
Ok I'm a bit closer to understanding it (I'm an Electrical Engineer not a Physicist). I've read the inertia article, so the planets are in inertial motion now yes? So did something have to accelerate them initially?
