Filaments of Galaxies

  • #1

Main Question or Discussion Point

Hey! Has anyone else heard of filaments of galaxies? Apparently galaxies fall onto galaxy clusters by first falling onto 'strings of galaxies' that feed the accretion. These filaments are supposed to connect galaxy clusters that are very close spatially.

I think this has something to do with the nodes and strings of matter in Cold Dark Matter simulations? This seems like an awesome concept to me and I would love to discuss it with other people!

You are on the right track. Quantum theory predicts filamentary distribution of matter as a consequence of inflation. Dark matter behaves more consistent with the expected quantum distribution because it barely reacts with anything else save by gravity, and is very abundant.
