In brief, any argument for the clumpiness
of the late universe should (since the early universe can be seen as just as much a gravitational collapse as the late) be equally an argument for the clumpiness
of the early universe.
Analysis of the clumpiness
of the dark matter in the maps will also allow scientists to probe the nature of the mysterious dark energy, believed to be causing the expansion of the universe to speed up.
He also explains the "Lyman-alpha forest," a way to measure the clumpiness
of matter by analyzing how light from quasars interacts with intervening clouds of hydrogen.
To account for the clumpiness
of the present-day universe, many researchers have invoked the notion of dark matter-weakly interacting, invisible material that doesn't glow like ordinary matter but does exert a gravitational tug.
Thus the clumpiness
of the dark matter maps provides a measurement of the amount of dark energy in the universe.
