if the density of the universe is higher than the critical density, the universe will:


Using numerical methods, the Friedmann Equation was solved using various parameters for the densities. In a flat universe, the universal expansion slows, but it never reverses into a contraction. Universes with densities either higher or lower than the critical density would show marked curvature. Calculations show that a universe with no curvature is one that is at critical density. In an open universe, the expansion continues forever. From the computations it was found that the age of the universe is mostly dependent upon the dark energy and matter components of the universe while the radiation density has less effect.

Universes with densities either higher or lower than the critical density would show marked curvature.

The critical density is simply that density which makes the SPATIAL curvature zero, or flat, a so called flat universe (words again, it really is only the spatial part that has no curvature, there is an expansion which makes the spacetime curved). Related Questions. This value is estimated as (1-3)×10^-26 kg/m³ and it’s calculated when you take the matter-energy density of the universe and divide it by the matter-energy density of the universe … This universe will stop expanding at some time in the future and begin contracting.
But we saw that the observations of the CMB, which show that the universe has critical density, rule out the possibility that space is significantly curved. As for how to see what the critical density is, we should turn to the Friedmann equation: Critical density is the value at which the Universe is at balance, and expansion is stopped.

Lastly, if the density of the universe is less than the critical density, then the universe is 'open.' less than the critical density and the cosmological constant is 0 The Rip the from NATS 1745 at York University If the Universe is at the critical density, then the total mass of the Universe is closer to 1e53 kg, and the number of atoms (assuming that most of the mass is in the form of hydrogen atoms) about 6e79. Asked in Density How does density change as the universe expands?

This model is called a closed universe and corresponds to the universe on the left in Figure \(\PageIndex{3}\). Density of universe? But we saw that the observations of the CMB in Figure 29.18, which show that the universe has critical density, rule out the possibility that space is significantly curved.

So if the density is equal to the critical density… Mean density: 9.9 × 10−30 g cm-3.
