the experimental method still works for events inside our universe, which are the only events we can see or test anyway
like i said, this is speculation, but i personally find it interesting.
Be careful of dangerous assumptions, especially ones that contain the word "only." You're basically saying that "extra-universal" things could never be detected. I think that, at root, you can only make such a claim if you believe that ours is the only physical universe there is. But if we suppose that other universes do exist, then there's a potential for interaction between them, and that should create observable phenomena -- for example, the guy being interviewed offers a couple of potential things to look for.
The question I have is: would numbers such as pi, or e, be subject to the same "anthropic adjustments" as, say, Planck's constant or the cosmological constant? Would math be equally applicable across all parts
