You just need to start with the right axioms. Everything mathematically possible that is not self contradictory (including a flat Earth and flying pigs). Brent I don't see dark bands as mathematically possible since these regions have 100% destructive interference. AGThey have destructive interference in a universe that satisfies quantum mechanics. How do you know there isn't a universe that satisfies Newtonian mechanics? or Harry Potter mechanics? Or Aristotelian mechanics? Brent So now you're saying that everything *conceivable* is possible. But isn't that what you criticized Jason for? AGYes, I did. And above I'm criticizing you for not recognizing the difference between nomologically impossible in this universe under the physics as we understand it, and Tegmark's everything mathematically consistent happens in some universe. BrentIn fact I looked up "nomologically" and I'm not clear as to your meaning. Jason said "everything conceivable", so you pointed out what amounts to destructive interference and flying pigs as things that don't happen in our world. Why do that, and then turn around and mention universes where QM doesn't work. Let's just say that Jason didn't misuse the term, and leave it at that. AG
Jason may well believe that everything conceivable happens. After all he's on the "everything" list. But he's wrong to think that quantum mechanics endorses that assumption.
