UC Berkeley Physicists Push Limits in Search for Dark Energy

New experiment with lattice atom interferometer achieves unprecedented precision in measuring gravitational effects.

Researchers immobilized cesium atoms to measure gravitational attraction with extreme accuracy.
The experiment found no deviations from Newtonian gravity but sets the stage for future discoveries.
The technique could eventually test the quantum nature of gravity, a long-standing scientific challenge.
Potential applications include advanced quantum sensing and geological mapping of the ocean floor.
The study builds on previous work and aims to detect hypothetical particles like chameleons or symmetrons.
