Universe Friedmann Equation. Dv dt hv 0 2 32 which reads the cosmological redshift as v 1 a. 4 2 friedmann equations we can now build our universe by taking for each point in time a robertson walker rw space.
From which we set up the differential equation. The friedmann equation which models the expanding universe has a parameter k called the curvature parameter which is indicative of the rate of expansion and whether or not that expansion rate is increasing or decreasing. Expanding universe first general relativistic models by einstein predicted a contracting universe 1917 introduction of cosmological constant by einstein 1922 the friedmann equation predicted an expanding universe 1928 georges lemaitre independently concluded the same lemaitre was the first to propose a primeval atom theory later known.

If you want to know where the universe came from and where it s headed all. Expanding universe first general relativistic models by einstein predicted a contracting universe 1917 introduction of cosmological constant by einstein 1922 the friedmann equation predicted an expanding universe 1928 georges lemaitre independently concluded the same lemaitre was the first to propose a primeval atom theory later known. The friedmann equation which models the expanding universe has a parameter k called the curvature parameter which is indicative of the rate of expansion and whether or not that expansion rate is increasing or decreasing. It indicates the future fate of the universe.
