the universe doing arts and crafts with gravity, hydrogen, and about 13 billion years of patience.
means the process by which matter clumps into stars, galaxies, planets, and everything else, driven by gravity acting on tiny density differences left over from the big bang.
from traces to observational cosmology and astrophysics of the 20th century, once telescopes and thermodynamics let scientists rewind the universe's tape from smooth gas to structured cosmos.
