Shortly after my father died the phone started ringing. My father was Hugh Everett III. When he was 24 he wrote a ground-breaking thesis about physics most commonly known as “the many worlds theory”. It challenged the accepted notion of how the world works in such a huge way, stating that there were actually countless versions of ourselves splitting off and going through as many different scenarios as you could imagine, and the physics powers that be (Albert Einstein, Niels Bohr) were having none of this. They weren’t about to let a 24-year-old knock their faces off the Mount Rushmore of physics. Getting no encouragement, my father gave up on quantum physics.
