I don’t think so. That is why Kolmogorov defines a measure space by forbidding infinite intersection of events. In the finite case the space of events is the complete boolean structure coming from the subset of the set of the possible results. In the infinite domain, the measure space os defined by a strict subset. I miss perhaps something, but the axiomatic of Kolmogorov has been invented to solve that “infinite number of value” problem. But I do agree that fine-tuning is not always well defined and sometimes misused. Yet I agree that the choice is between a fine tuner (but who is it, and how does it the selection. Even if real, a fine tuner explains nothing without some explanation of where the fine tuner comes from. In a multiverse or milti-computations (le the sigma_1 arithmetic) consciousness is the fine tuner, and that one is explained already by the (Löbianà universal machine. > Fine tuning is all in the intuition.

That depends on your OMEGA in the probability space, and the measure you put on the set of events. > > Second, calling it "fine-tuning" implies some kind of process of "tuning" or > "selection". But that's gratuitous. Yes.
