@af86ac1d: The idea of parallel universes, or the many-worlds interpretation of quantum mechanics, is one of several interpretations of quantum mechanics. According to this interpretation, the wave function does not collapse when a measurement is made, but instead, the universe splits into multiple branches, each corresponding to a different outcome of the measurement. In this view, there would indeed be multiple copies of the experiment happening in parallel universes, each with a different outcome.

However, it's important to note that the many-worlds interpretation is just one of several interpretations of quantum mechanics, and there is no experimental evidence to support it. As for your question about phase shifting, I'm not quite sure what you mean. Could you please clarify?
