Maybe there are no secrets, but every time a new experiment is conducted, the universe randomly decides the outcome and then sticks to it?
I think this is what we assume about small things already, like the position of a previously unmeasured photon or the spin of a previously unmeasured electron, right? Neither the photon has a position, nor the electron has a spin, but we measure one. And from then on, the the universe acts according to the measured values.
- bratbag 3y agoMaybe, but from a practical perspective even if this crazy hypothesis were true, the distinction is irrelevant.
- mg 3y agoWhy is it irrelevant for the universe, but not for electrons?
- guerrilla 3y agoIf that were true, what difference would it make? We would do everything exactly the same as how we would otherwise. There's also no way of testing your hypothesis becauase of that. It might fit well in a good hard sci-fi novel though. "Consider the practical effects of the objects of your conception. Then, your conception of those effects is the whole of your conception of the object."

- guerrilla 3y agoThis isn't true. This is exactly why we have multiple interpretations of quantum mechanics.
- mg 3y agoThere are always infinite interpretations of everything. But the "no hidden variables" theory is the most popular and well tested theory about whether things have a state before we measure it. And it postulates that they don't.
- guerrilla 3y agoIt's not tested at all. No local hidden variables is just a priori true though. It's not part of any interpretation. All of them are subject to it. This is irrelevant though because there are alternatives to local hidden variables like pilot wave theory, the so-called many words interpretation, relationalism (i.e. inherent nondeterminism) and there's no way to test between any of them.
- mg 3y agoIt's not tested at all This is what Wikipedia says about hidden variables: https://en.wikipedia.org/wiki/Quantum_mechanics https://en.wikipedia.org/wiki/Quantum_mechanics Many Bell tests have been performed and they have shown results incompatible with the constraints imposed by local hidden variables.
