Question

derive expression for ciritical density
​

Answer 1

• Critical density is the value at which the Universe is at balance, and expansion is stopped.

• This value is estimated as (1-3)×10^-26 kg/m³

• It's calculated when you take the matter-energy density of the universe and divide it by the matter-energy density of the universe that is required to achieve that balance.

hope it helps you mate.
