Schrödinger's cat:

a thought experiment, usually described as a paradox, that Austrian physicist Erwin Schrödinger devised in 1935.

Copenhagen interpretation of quantum mechanics

implies that after a while, the cat is simultaneously alive and dead. Yet, when we look in the box containing it and a poison and a radioactive source, we see the cat either alive or dead, not both alive and dead.
