What If Physics IS NOT Describing Reality?
Summary
This episode explores informational interpretations of quantum mechanics, arguing that physical laws model our knowledge rather than objective reality. It details Anton Zeilinger’s proposition that quantum systems consist of elementary bits of information, explaining phenomena like entanglement and the uncertainty principle as limits on extractable data. The discussion also touches on John Wheeler’s "it from bit" concept and the wave-particle duality.
