Though if we reflect on what physics can theorize, we might be comforted by the notion (or traumatized by it?) that all of those scenarios I mentioned (that are excluded from ‘occurring’ because some other variation of them occurs, instead of them), and that are exponentially large in number (maybe even infinite), do have a reality, at least philosophically, and perhaps even actually (if we can abide the theory of parallel universes, or of a multiverse, which allows that each strand of possibility, in each moment of time, somehow finds its own substance, and continues on, like a domino effect, into ethers of essentiality). Though the continuum of scenarios we regard as ‘our history,’ being self-contained and integral (and discontiguous with any other history), does not seem to permit us to experience any reality but one (the one that we are ‘in’).
