Beyond the Quantum
Antony Valentini, Oxford University Press
Physics has faced challenges in recent years, with unanswered questions on dark matter, the Higgs boson, and string theory. In a refreshing approach, Antony Valentini from Imperial College London presents a bold idea in his book Beyond the Quantum: A quest for the origin and hidden meaning of quantum mechanics.
Valentini delves into the mysteries of quantum mechanics, focusing on the wave function that describes the state of particles. While traditional interpretations struggle to explain the wave function’s nature, Valentini explores pilot-wave theory, which suggests that particles are guided by a real but incomplete wave function, akin to how waves steer objects on water.
This theory, first proposed by Louis de Broglie and later developed by David Bohm, aligns with quantum mechanics’ predictions but removes the inherent randomness. Valentini proposes that particles were initially far from equilibrium in the early universe, gradually reaching their current state and shedding light on the randomness observed in quantum mechanics.
Valentini’s work hints at the possibility of superluminal communication in the past, challenging conventional notions of locality and offering a fresh perspective on the fundamental principles of quantum mechanics. While the pilot-wave theory awaits further evidence, Valentini’s innovative approach showcases the essence of a groundbreaking idea in a field seeking new directions.
