One of the thought experiments in quantum mechanics. Also called Schrödinger's cat box.
Criticism of the "Copenhagen Interpretation" which is the basis of quantum mechanics. It was proposed by theoretical physicist Erwin Schrödinger. In quantum mechanics All events are established at the moment they are observed. Until it is on the verge of being established, multiple different events exist in a state that overlaps with each other. is the premise. However, if this is correct, then ``a single cat exists simultaneously in multiple states, ``alive'' and ``dead,'' before it is observed.'' He used an analogy: ``If you lock a cat in a box with a device that releases poisonous gas with a random probability, the chances of the cat dying and the chances of it being alive overlap until the next time you open the box. He pointed out the strangeness of quantum mechanics. This thought experiment has since become known as Schrödinger's cat.
