Universes Give Rise to Alternative Realities
Electrons can be in two states at the same time, until a measurement determines the state. According to quantum theory, the rejected state could disappear into a newborn parallel universe.
Scientists know that ordinary objects from our world can only exist in one physical state at a time. But in the world of quantum mechanics, the rules change. Here, an atom or electron can be in two different states at a time – also known as superposition. An electron can rotate clockwise and counter- clockwise at the same time. The superposition is continued, until an observer makes a measurement that shows the direction of rotation. The measurement "locks" one state, deactivating the other.
However, another quantum theory interpretation rejects that superposition stops with the measurement. Instead, the other state is realized in a new daughter universe. The quantum theory interpretation involves that entire universes can be in
superposition. Each time a situation is determined by an observer in a universe, and the superposition is broken, new universes materialise.
