Part 2/9:
Before diving into Rovelli's theories, it’s essential to summarize what was covered in the previous discussions. The initial conversation with philosopher Elise Crow laid the groundwork for understanding quantum mechanics. The core idea presented was that, within this framework, reality is probabilistic rather than definite until an observation or measurement is made. This leads to the quantum measurement problem, a mystery concerning how multiple potential outcomes collapse into a singular observed reality.
In the second conversation with physicist Sean Carroll, various interpretations of quantum mechanics were discussed, including spontaneous collapse theories and the famous many-worlds interpretation, which suggests every quantum possibility actually occurs across branching universes.
