Comment on Why is space 2 dimensional?
spankmonkey@lemmy.world 11 hours agoSo, the star and planets all started as one big gas nebula, then the nebuka as a whole started spinning due to uneven distribution of matter within the cloud as it condensed. This spin increased over time and as the sun formed in the center, and planets clumped around in its orbit. The spin relative to each other, along with some interesting collisions between massive bodies, is why a few don’t fit the general mold of spinning the same ways on the same plane. We may have even picked up a planet or teo over time that was ejected from another solar system!
This video does an ok job of explaining the spinning and planet formation part. I’m sure thete are better ones out there.

It’s like how the earth bulges out at the equator.
The momentum pulls them out, gravity pulls it back. Similar thing at the solar and galactic planes.
They “bulge” relatively to the spin of the material over time and the clumps of material then forms planets along that general plane.
