The end of physics as we know it?
Prof. Dr. Caslav Brukner, Prof. Dr. Renato Renner and Dr. Eric Cavalcanti just won the Paul Ehrenfest Best Paper Award for Quantum Foundations. Their different no-go theorems make us reconsider the fundamental nature of reality. Bell’s theorem in quantum mechanics already confronted us with the fact that locality and ‘physical realism,’ in the sense that particles have predetermined physical properties prior to measurement, cannot both be true. But in certain variations of the Wigner’s Friend thought experiment an additional metaphysical assumption is now also put in question: the absoluteness of facts. In different words: can we safely assume that a measurement outcome for one observer is a measurement for all observers?
