Spacetime

The image depicts an experiment in which heavy particles (illustrated as the moon), cause an interference pattern (a quantum effect), while also bending spacetime. The hanging pendulums depict the measurement of spacetime. The actual experiment is typically performed using Carbon-60, one of the largest known molecules. The UCL calculation indicates 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 which constrain any theory where spacetime is treated classically. One is the weighing of a mass, the other is an interference experiment.

New theory unites Einstein’s gravity with quantum mechanics
