Part 3/9:
The Transition from Possibility to Reality
As the dialogue begins, Rovelli emphasizes that the quantum measurement problem remains an open question, a conundrum that’s perplexed scientists for over a century. He refrains from outright endorsing mainstream interpretations like the many-worlds theory, instead advocating for a reconsideration of how we understand the wave function—the mathematical description of quantum states.
According to Rovelli, one perspective on quantum mechanics suggests that the wave function is not an object in itself but a computational tool—a way of calculating where particles will likely be found. He likens this to classical mechanics, where probabilities guide predictions rather than defining reality.
