"Schrödinger is a human on most Earth-like planets. A brilliant one at that. He posited a thought experiment, wherein... well, I will not go into full detail, but the summation is that he was attempting to disprove an interpretation of his life's work. He posited that a cat be left in a sealed box with a flask of poison, theoretically speaking. Then he posited that the box was monitored by a device which would, at the subatomic level, detect a change and automatically break the flask, or would detect no change at all and not automatically break the flask. The cat in the box would be, according to this particular interpretation, both alive and dead whilst the box was sealed, as there would be no way of knowing if the change had occurred or not. But clearly, the cat would be either alive or dead when the box was opened and observed."
