Oh, so original MWI is consistent with quantum tunneling?mfb said:That is an objection to a proposed modification of MWI ("many interacting worlds"), not to MWI itself. I removed it from the article.
The problem of quantum tunneling refers to the phenomenon in quantum mechanics where a particle can pass through a potential barrier that it does not have enough energy to overcome. The Many Worlds interpretation suggests that every time a quantum measurement is made, the universe splits into multiple universes, each representing a different outcome of the measurement.
The Many Worlds interpretation posits that in the universe where the particle is measured to have tunneled through the barrier, there is a copy of the observer who has also observed the particle on the other side of the barrier. This allows for all possible outcomes of the tunneling event to exist in different universes.
One implication is that there are an infinite number of parallel universes, which can be difficult to conceptualize. It also challenges the idea of a single, objective reality and raises questions about the role of consciousness in determining reality.
While there is no conclusive evidence for or against the Many Worlds interpretation, some experiments, such as the delayed choice quantum eraser experiment, have been interpreted as supporting this theory. However, other interpretations of quantum mechanics can also account for these results.
The Many Worlds interpretation is one of many interpretations of quantum mechanics and is still a topic of debate among scientists. While some physicists, such as Stephen Hawking, have expressed support for this theory, others remain skeptical and prefer alternative interpretations.
