I'm asking this just out of curiosity on my part.<grin> When I first heard of cosmic inflation, a long time ago, I went to the local university library to look at papers that made estimates of the total number of e-folds from various models. I'm not an expert in any area of science but I found the idea fascinating.(adsbygoogle = window.adsbygoogle || []).push({});

I found one in the popular magSky and Telescopethat stated the early universe possibly went through 3000 e-folds and was now roughly ten to that power of light years across! The most inflation I found (and made a Xerox of) by Indian theorist T. Padmanabhan in the 1980's stated that, if a "natural" value of λ was used, there were 10^{720 }e-folds and a resulting space e^10^720 cm across.

A more recent article concerning low scale inflation had 10^{28}e-folds if certain parameters were used.

I was wondering--as I say, just curious--if anyone had heard of similar ginormous (but not infinite) amounts of inflation en total.
