In Beyond the Quantum: A quest for the origin and hidden meaning of quantum mechanics, he presents something almost antiquated in its rarity: a big idea. As the title suggests, his central target is quantum mechanics, which has underpinned physics for a century. “ Pilot-wave theory has long been known to reproduce all the predictions of quantum mechanics “The other answer is that the wave function isn’t the whole story. Pilot-wave theory has long been known to reproduce all the predictions of quantum mechanics, with no fundamental randomness. Given the lack of evidence, this might sound a bit wild were it not for Valentini’s meticulous analysis of how orthodox quantum mechanics came to hold sway (the book is worth reading for this alone).
