وهذا يعادل كثافة كتلة مقدارها 9.9 × 10−30 g/cm3، وهو ما يعادل فقط 5.9 بروتونات لكل متر مكعب.” The WMAP data are consistent with a flat geometry, with Ω = 1.02 +/- 0.02.
This is equivalent to a mass density of 9.9 × 10−30 g/cm3, which is equivalent to only 5.9 protons per cubic meter.” The WMAP data are consistent with a flat geometry, with Ω = 1.02 +/- 0.02.
