John Wheeler, who is mentor to many of today’s leading physicists, and the man who coined the term “black hole”, suggested that the nature of reality was revealed by the bizarre laws of quantum mechanics. According to the quantum theory, before the observation is made, a subatomic particle exists in several states, called a superposition (or, as Wheeler called it, a ‘smoky dragon’). Once the particle is observed, it instantaneously collapses into a single position (a process called ‘decoherence’).
