👉 Schrödinger's cat is a famous paradoxical statement that was proposed by Albert Einstein in 1935. It states that if two particles are simultaneously observed to be in the state of being both not and neither, then they must be either both or neither. In other words, "there exists a universe with an infinite number of possible outcomes." This statement is often used as a metaphor for the possibility of multiple realities or paradoxical situations where one can exist at once.
