Any quantum physicists here? The cat is a macroscopic object. Actually the hammer and the detector already are. So any quantum phenomena like superposition are gone by the time the detector experiences something like a voltage in an amplifier. The detector is already the observer.

- Gravityloss 2y agoHmm, so in your theory, if the box could be a perfect disturbance barrier, the cat would actually be in superposition? What's then preventing to scaling this to the whole universe and everything being in superposition all the time?
- zajio1am 2y agoThat is pretty much what many-worlds interpretation of quantum mechanics says.
- 082349872349872 2y agoIn my/Gell-Mann's theory, the universe decoheres the box, randomising its phases, and it in turn decoheres its contents. If you can find a perfect disturbance barrier, you can put qubits inside. Now the problems which would remain be: how to initialise them, and how to read out the final result...
- habinero 2y agoThe point of the gedanken experiment is it's mocking quantum mechanics. It's supposed to be ridiculous.
- Gravityloss 2y agoExactly! But people interpret it as being true.
