Infinite doppelgangers and quantum probabilities

infinite ONE 300x300 Infinite doppelgangers and quantum probabilities Could your identical twin be living exactly the same life as you in any number of parallel universes ?


An identical copy of you is also reading this story. This twin is the same in every way, living on an Earth and in a universe that looks exactly like our own. And there may be an infinite number of them.

In the uncertain, fuzzy world of quantum mechanics, particles do not have fixed properties until they are observed. Instead, objects that obey quantum rules exist in a “superposition” of all their possible states simultaneously.
