SUMMARY
The term "density in units of critical density" refers to the measurement of baryonic matter density in cosmology, expressed as a ratio to the critical density of the universe. The critical density, defined as 9.9 x 10-30 g/cm3, is the density required for the universe to be geometrically flat. Understanding this concept is essential for analyzing the distribution of baryons in the cosmos.
