Jonathan Oppenheim교수도 자신의 post quantum gravity이론을 위해 실제 실험을 제안했죠

양자장에 영향을 받는 중력(Gravity coupled quantum field)이 핵심아이디어인데 

Einstein 방정식을 Langevin 방정식에서 노이즈소스를 양자요동(quantum fluctuation)으로 두어서 식을 새로 만들었습니다

측정으로 인한 반작용 (back action)이 클래식한 시스템의 기하공간(metric)에 영향을 미치는 것으로 해석했습니다


그리고 자신의 이론을 테스트 할 수 있는 실험제안 까지 했습니다

Gravitationally induced decoherence vs space-time diffusion: testing the quantum nature of gravity - Nature Communications

Consistent theories have been proposed in which spacetime is treated classically while matter remains quantum. Here, the authors prove that such theories are constrained by a trade-off between the decoherence induced in the quantum system, and stochasticity in the classical one, providing a way to experimentally test the quantum nature of gravity.
