For decades, physicists have argued that making sense of gravity and quantum mechanics meant joining one of two camps: string theory or loop quantum gravity. Both treat the quantisation of spacetime as unavoidable. But UCL quantum information and quantum gravity theorist Jonathan Oppenheim argues for a radical third way: one where gravity remains fundamentally classical, provided it contains a built-in element of randomness. His idea not only challenges dominant theories, but opens up the possibility of testing experimentally whether gravity is truly quantum.
