So quantum mechanics are very weird.
A lot of times systems of very tiny particles behave as if they’re in many different states at the same time until we observe them. When we observe them, they seem to only be in one state. This “being in many different states at the same time” phenomenon is called superposition.
Schrodinger’s cat is a thought experiment to demonstrate how the weirdness of superposition doesn’t really gel with what we observe in the macroscopic world.
The thought experiment links something we can directly see exhibits superposition, a radioactive nucleus decaying, to whether or not a cat gets poisoned, which we really consider to not be a situation where superposition applies.
