- TL;DR Summary
- Carlo Rovelli and Enrico Calloni are going to a cave under Sardinia to have vacuum energy tilt a high-precision balance.
Vacuum energy is predicted by Quantum Field Theory, and also independently corroborated by recent observations in cosmology involving accelerated expansion. More corroboration occurs in superconducting cuprates exhibiting quantum criticality, and in the Casimir effect
The island of Sardinia sits west of Italy, and abandoned mines there are ripe ground for seismically quiet passages. Scientists Enrico Calloni (et al) are going to set up a type of interferometer that operates by a high precision balance. One of the hanging bob masses will change its electrical properties, while the other one remains the same. Because of cancellations in vacuum energy, via Casimir effect, it is proposed that the cantilever will tilt by nanometers, detectable to the interferometer. The amount of difference in force between the two bobs is estimated at 10-16 Newtons.
When a large solid mass is submersed in water, it will experience a buoyant force upwards equal to the amount of water its volume displaces. This principle was first discovered by Archimedes many centuries ago. Analogously, the Casimir effect can cancel out certain wavelengths of vacuum fluctuations, in which case the net impinging vacuum energy on a bob will create a vacuum buoyant force . The experiment in Sardinian caves is allegedly going to measure this force. Thus, this project is dubbed The Archimedes Experiment.
