"High-resolution measurements of CMB show that the universe at this time was extremely--but not perfectly--uniform. Subtle irregularities in the density of matter eventually enabled gravity to do its thing. Starting around 200 million years after the Big Bang, regions with slightly greater concentrations of dark matter and gas started collapsing into the first stars and protogalaxies."
