American physicist Hugh Everett first put forward the many-worlds interpretation in 1 955 when he was a Ph.D. student at Princeton University. However, the many-worlds interpretation conflicts with another approach to quantum mechanics known as Nobel Prize-winning physicist Niels Bohr’s Copenhagen interpretation from 1920. With quantum immortality, “you have a Schrödinger’s cat-type situation,”Kipping says, “but instead of the decay causing the death of the cat, it’s the death of you.”Essentially, quantum immortality demonstrates the many-worlds interpretation of quantum mechanics. This concept has implications beyond quantum mechanics because it also brings up questions of the mind. And in the realm of tangible experiences, which are much closer at hand than quantum mechanics, this experiment could bear upon near-death experiences.
