ΩM=0.28\Omega_M = 0.28

Why this formula appears here

What actually happened next is the part worth stating precisely. In 1998, two independent supernova teams measuring the expansion history of the universe with distant Type Ia supernovae found that the expansion is accelerating, and the Supernova Cosmology Project’s analysis of forty-two high-redshift supernovae reported, for a flat universe, a matter density of ΩM\Omega_M = 0.28 with combined statistical and systematic uncertainties of a few hundredths, and stated that the data indicated a nonzero, positive cosmological constant at 99 percent confidence [ 3 ] . That result places the implied vacuum energy density at roughly ΩΛ\Omega_\Lambda ≈\approx 0.7 — a value sitting comfortably inside the…
