> It is straightforward to show QM isnt a linear theory in anything other than an inf-dim space. Even if this were strictly true, which it's not for any real purpose, it's completely irrelevant because reality is non-linear. This non-linearity is how we get probabilities out of QM. Unless of course you're merely assuming a particular interpretation of QM that says otherwise, like MWI, but then I have no reason to accept this premise so your argument is still unconvincing. > There is overwhelming evidence they are not, and no evidence they are. In fact, the opposite is the case, and we don't even need any fancy arguments to demonstrate this: if what you say were true then a trivial proof refuting the Mathematical Universe hypothesis would have been published years ago. No such proof exists.
