That much? I thought models that considered a duration of 10^-32s with an expansion of e^60 ~ 10^26, which would mean 10^54 for each second... That is on average. I'd like to know the peak rate.
The amount of expansion is commonly given in terms of the number of e-folds of expansion, N, where [itex]a(t) = a(t_i)e^{N}[/itex]. From this expression the rate of change is seen to be
[tex]\frac{dN}{dt} = H[/tex]
