As far as I know galaxies are relativly flat. And I'd say our solar system is also quite flat too, when I look at the orbits of the planets. I've read that the reason is rotation? I can picture a new object coming into a flat system which already has a certain rotation and which will adjust over time to that system. But when and how did the rotation start and why does it seem like the vast majority is flat?
