Gravity refuses to obey quantum rules, and this is not a bug but a possible key to a unified theory. Physicists are increasingly considering the idea that space-time itself is not quantum, but merely "winks" at quantum systems with stochastic fluctuations.
In September 2026, New Scientist published an article about the work of Jonathan Oppenheim of University College London. Back in 2023, he made a bet at odds of 5000 to 1 that gravity is not quantized. His post-quantum model suggests that classical gravity interacts with quantum fields through random "glitches" — small unpredictable deviations that do not require quantizing gravity itself.
In ordinary life, a superposition of masses looks like an impossibility: an object simultaneously here and there. In post-quantum gravity, such a superposition causes tiny but measurable fluctuations of the gravitational field, like a light breeze from an invisible pendulum that swings in two directions at once and each time nudges space-time slightly differently.
This model solves two problems at once. First, it avoids the monstrous complexity of quantum gravity — strings, extra dimensions and emergent space-time. Second, Oppenheim's calculations show that the same stochastic effects could explain the nature of dark matter, which remains one of the main mysteries of cosmology.
The theory is proposed to be tested with experiments involving superpositions of massive objects: if gravitational "glitches" really do arise, they will be possible to register under laboratory conditions. For now this is only a theoretical construct, but it already forces us to reconsider what exactly should be considered fundamental in physics.
The results and ideas are set out in detail in the New Scientist article of 28 September 2026. If the model is confirmed, our conception of reality will become simpler and at the same time stranger: gravity is not quantized, it simply sometimes "makes noise."
