| Jul 6, 2020 at 20:42 | comment | added | Charles Francis | I never found a solution filling in the missing steps. At best, textbooks (and I have at least five) just seem to leave this as an exercise. I have given a complete derivation of the Friedmann equation in my third book, for the case with curved space and cosmological constant, but it takes six pages of calculation, so I can't give an answer here. | |
