Friedmann Equation With Cosmological Constant. 10 70 m2. The value is based on recent measurements of vacuum energy density ρ vacuum 5 96 10 27 kg m 3.
The friedmann equation itself is independent of the equation of state and just says h 2 r 2 kc 2 1 whatever the form of the contributions to. It is often expressed as 10 35 s 2 by multiplication with c2 i e. The result is f 1 1 kr2 where k 1 0 or 1.
The resulting metric called the robertson walker metric is.
The other one is and has always been radiation dominated. One of them is and has always been matter dominated. 10 70 m2. The resulting metric called the robertson walker metric is.
