Schrodinger’s Cat thought experiment: a cat, a flask of poison and a radioactive source are placed into a box and sealed. The flask of poison is shattered, releasing the toxin that kills the cat. There is supposed to be 50% of this happening. So the interpretation of quantum mechanics implied that after a while, the cat was simultaneously alive and dead at the same time. Although, when one looks into the box, either you see it as alive or dead, not oth alive and dead. This experiment proved that there can be more than one correct answer other than the one that is physically right.
