- TL;DR Summary
- Planets, stars, and galaxies were formed from dust accumulation/accretion, but where did the dust come from?
I've looked for a while and can't find an answer to this, hence the post. Ultimately this is a question about how the first pieces of "classical" matter formed from quantum matter. My study of self-organizing systems shows that you need a hierarchical build-up of structures to allow a complex system to form. Just as you can't build a living plant (or animal) from bacterial cells (you need eukaryote cells); you can't build a planet from quantum particles, you first need classical matter. That "classical" dust accumulates/accretes into larger and larger objects until a star can form.
So is there a paper or discussion about how the first pieces of classical matter formed?
