What Schrödinger’s cat REALLY means

So the quantum world has roughly twice the potential of information that can be expressed by any specific function. Makes sense for a virtual particle field, to make the physical you actually need to remove half the information by introducing a function or vice versa. I don't think it means there are infinite parallel universes so much as half the universe can never exist in the same place at the same time or else neither half could exist at all. When you observe a wavefunction with a detector obviously you are inherently prohibiting half of what it could be in order to observe any of it at all, like the way a negative particle must be removed for a particle in a virtual particle field to become an actual particle, or like the way Hawking radiation works.
I wonder if there's math that can demonstrate that, not that it happens that's what you're referencing, but why which actually makes sense. Maybe look at Hawking's math for his radiation?
