Good day to you all,
I'm very sorry since there are countless of topics that have discussed this question before. Call me dumb, but I've read almost every single one of them and I'm still having a bit of a hard time understanding why most galaxies have their planets, stars, dust, gas etc. all rotating in one 2D plane. If someone could explain this to me in simple layman terms I'd appreciate it very much.
I keep seeing people talking about conserving the angular momentum but I don't get HOW the angular momentum gets conserved that way. How does the angular momentum look like before and after the galaxy being a flat disc formula-wise?
My theory what I think so far, is that a galaxy always starts with two relatively large particles orbiting each other. They got larger because smaller dust particles interacted and fused together. Since they're larger than other particles and thus having a stronger gravitational pull, that means all the other smaller particles get pulled towards them. The plane on which the 2 large particles orbit each other in the beginning, will be the very same 2D plane on which ALL of the other particles will eventually orbit. Is this correct?
Looking forward to your explanations
