The Copenhagen interpretation and the Many-Worlds theory of Quantum Mechanics. What's the difference?
Quantum mechanics is the branch of physics that studies the behavior of matter and energy at the subatomic level. But when it comes to understanding this strange and puzzling world, there are two competing theories: the Copenhagen interpretation and the Many-Worlds theory. Many scientists, including the world-renowned physicist Albert Einstein, were skeptical of quantum mechanics when it first emerged. They believed that the theory was incomplete and that there had to be more to the picture. Yet two interpretations of the theory have emerged, and both theories provide answers to some of the most profound questions in physics. The first theory is the Copenhagen interpretation, named after the famous 1920s Solvay Conference held in Copenhagen. This interpretation posits that a particle's behavior is not deterministic and is instead determined when it is observed. So, until an observer observes a particle, the particle exists in a state of superposition where it can exist in multiple...
