In quantum mechanics there has been more different interpretations than religions trying to explain the "creation" it seems. I remember when Afshar Experiment was conducted John G Cramer immediately used the results to advocate his own pet theory while saying Copenhagen and MWI was falsified. Which it somehow turned out they wasn't. Niels Bohr verbally "attacked" anyone who went against CI (his pet theory) and said his theory was the only that could work with the formalism (boy was he wrong) And the worst of them all, David Deutsch who make false claims that he has proven MWI and that all other interpretations are actually parallel universe interpretations in denial. CI, Bohm, TI, all are single universe theories, with NO other made up universes. Yet he's claiming this several times. I just wonder, what makes physicists willing to ignore truth and make false claims to promote their own pet theory? Are they all deluded and don't understand that even if they delude themself to believe in their false theory it doesn't make it right?
