My guess is he is using something like the number of distinguishable quantum states given by the Bekenstein bound, or the total number of degrees of freedom for the 10^23 molecules of gas in a cubic meter of air. And why are physicists like Tegmark and Greene still talking about the > measure problem if the number is finite? > I am not sure, perhaps they are considering it as infinite across a spatially infinite universe. But we only have access to a finite portion of the universe, so perhaps it is fine to ignore the rest of it (infinite space and universes) at least as it may relate to the measure problem.
