Two renowned theoretical physicists collaborate to analyze an experiment and what that means for quantum mechanics and gravity. I have not posted very much on quantum mechanics on this website, mostly because I don’t understand it or at least accept the current interpretation of the understanding of it. I don’t understand/accept the Copenhagen interpretation of quantum mechanics. At the core I think it is a measurement problem and not an ontological incoherence. But then again, maybe I am just a dumb layman who is just not smart enough to see the King is adorned with a beautiful garment rather than having no clothes.
Penrose had been a longtime skeptic of QM so this interview was fascinating. I’ve included the link to the paper they are referencing below.
Observation of the quantum equivalence principle for matter-waves
