Well, I was elaborating on Bruno's statement that worlds ("maximal
consistent set of propositions") of a FS are not computable; that even given
infinite resources (ie. infinite time) it is not possible to generate a
"complete" world. This suggests to me that it is *not* the case that given
infinite time, eveything that can happen must happen. I must admit this is
not my area of expertise; but it seems to me that the only other option of
defining a world (identifying it with the FS itself) will, by Godel's
incompleteness theorem, necessitate that there exist unprovable true
propositions of world; the world will be incomplete, so again, not
everything that can happen will happen.
Bruno?
