Using the physical conditions present in the universe during the era of recombination (T=3000 and pm=10^-18 kg/m^3), show by calculation that the Jeans length for the universe at that time was about 100 ly and that the total mass contained in a sphere with this diameter was about 4x10^5 Msun.© BrainMass Inc. brainmass.com October 25, 2018, 2:40 am ad1c9bdddf
