MTW section 27.7 states:
My question: does this mean one cannot push the basic Friedmann equations that were discussed so exhaustively in the locked thread 'Firedmann Fun' to a time before t ~ 1 second without gross errors?
If so, can someone please point to a fairly recent accessible paper showing how to deal with the time since inflation ended, up to 1 second? (Or better still, tell us how!)
It then proceeds to derive the relationships: [itex]\rho_m a^3 = [/itex] constant and [itex]\rho_v a^4 = [/itex] constant that pervect has shown before.All estimates indicate that, except for the first few seconds of the life or the universe, the energy exchanged between radiation and matter was negligible compared to [itex]\rho_m V[/itex] and [itex]\rho_r V[/itex] individually (see section 28.1). Under these conditions equation (27.31) can be split into two parts: ...
