WebThe velocity of recession of a galaxy can be considered as its escape velocity from the rest of the Universe. By Hubble's formula: Velocity of recession (v) = HR where R is the … WebThere is a special value of the density that causes the Universe to have zero curvature. It is called ρ c r i t, the critical density: ρ c r i t = 3 H 2 8 π G If the current density is equal to the critical density, then the left side of the Friedmann equation equals 0, implying that k = 0.
