A few caveats: The many-worlds interpretation isn’t really orthodox in the scientific community. I personally feel it’s nonsense—any solution that requires the constant creation of entire new universes to explain away our ignorance of fundamental quantum processes is really no solution at all. In addition, the gentleman who came up with the latest many-worlds-interacting theory is an economist, not a physicist. Earning a Ph.D. doesn’t make you an expert in everything.
