  • Now Antoine Tilloy at the Max Planck Institute of Quantum Optics in Garching, Germany, has attempted to get at gravity by tweaking standard quantum mechanics. Tilloy has modified the GRW model to show how it can lead to a theory of gravity. In his model, when a flash collapses a wave function and causes a particle to be in one place, it creates a gravitational field at that instant in space-time. A massive quantum system with a large number of particles is subject to numerous flashes, and the result is a fluctuating gravitational field. It turns out that the average of these fluctuations is a gravitational field that one expects from Newton's theory of gravity. This approach to unifying gravity with quantum mechanics is called semiclassical: gravity arises from quantum processes but remains a classical force.
