New research shows that during the early universe cosmic filaments ferried cold gas and embryonic, node-shaped galaxies to a dark matter halo, where it all clumped together to form massive galaxies. The larger the galaxy, the more cold gas it needs to coalesce and to grow from a source of cold molecular gases totaling as much as 100 billion times the mass of our sun.
