Illustration from PRX depicting an artistic version of Figure 1, from “A postquantum theory of classical gravity” (IMAGE)
Caption
The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The hanging pendulums depict the measurement of spacetime. The actual experiment istypically performed using Carbon-60, one of the largest known molecules. The UCL calculationindicates that the experiment should also be performed using higher density atoms such as gold. The other two images represent the two experiments proposed by the UCL group, both of whichconstrain any theory where spacetime is treated classically. One is the weighing of a mass, the otheris an interference experiment.
