In this episode Chiara Marletto and Professor Vlatko Vedral discuss a pioneering experiment that could reveal the quantum nature of gravity, putting Einstein’s classical general relativity to the test. They examine how quantum‑information methods and Constructor Theory might reshape our understanding of fundamental physics.
