"Harmonizing Gravity and Quantum Mechanics: A New Approach"

Jonathan Oppenheim at University College London has developed a new theoretical framework to unify quantum mechanics and classical gravity without the need for a theory of quantum gravity. His approach allows gravity to remain classical while coupling it to the quantum world through a stochastic mechanism. This new stochastic framework describes a single "classical quantum state" that predicts the system's probability of existing in a region of phase space and its quantum state in that region, preserving the unique characteristics of both quantum mechanics and classical gravity. Oppenheim's proposal challenges firmly rooted assumptions while remaining consistent with long-established physical laws, but it also raises conceptual difficulties, such as the potential loss of quantum information in a black hole.
