Query: A plausible upper limit on the number of e-foldings   Based solely on the arguments relating Friedmann equation and the Cardy
formula we derive a bound for the number of e-folds during inflation for a
standard Friedmann-Robertson-Walker as well as non-standard four dimensional
cosmology induced by a Randall-Sundrum-type model.
