Friedmann 1888 1925 the man who made the universe expand soviet mathematician and meteorologist most famous for contributions to cosmology first person to mathematically predict an expanding universe 1922 derived from einstein s general relativity einstein initially dismissed friedmann s equations. The friedmann equations are a set of equations in physical cosmology that govern the expansion of space in homogeneous and isotropic models of the universe within the context of general relativity. C o o c h 0 2 a 0 2 where a 0 and h 0 are separately the scale factor and the hubble parameter today.
The equations for negative.
But the evolution of the hubble parameter a kind of rate of expansion is given by the friedmann equation. We would like to know whether the universe is. Take the time derivative 2 a a 8πg 3c2 ǫa 2 2ǫaa divide by 2 aa a a 4πg 3c2 ǫ a a 2ǫ. C 3h 0 2 8p.
