Can’t afford to stay at a Holiday Inn Express, so I had to look up Nebular Theory. Quite interesting. Thanks.
Yeah, in a nutshell, whatever debris doesn’t share a ‘common’ angular momentum will collide, cancel out, and fall to the center. Our own sun must have formed from a nebula that had some spin applied to it, from a passing star or whatever. As the nebula collapsed under gravity, it spun faster like a ballerina, and anything not sharing the ‘preferred’ spin didn’t survive long. But that’s only a tiny percentage of the total mass.
