The scholars imagined that if you put a hypothetical cat inside a box with poison and a mechanism to time-release the poison, then after a certain amount of time, the cat is simultaneously both dead and alive. The cat is only decided one or the other once an observer opens the box to see. This thought experiment illustrates the issue of quantum superposition in the field of quantum mechanics.
