I have been reading extensively about the thought experiment, called Schrödinger’s Cat, and have reached a personal conclusion that it is inherently flawed by its idealism. There is no case where any object inside “the box” can be fully shielded from decoherence. There is no example of this in nature. Every case for the validity of the experiment is baseless. Interestingly enough, this is what Schrödinger was out to demonstrate and with which Einstein agreed. What hadn’t been explored at the time was entanglement can be explained simply by additional dimensions.
