What happens when you put Einstein’s theory of gravity to the test in the quantum world? ✨
In an experiment carried out at Ben-Gurion University of the Negev, an international research team used ultracold atoms to measure what happens when part of an atom’s quantum wave falls freely while another part stays in place. The result matched a prediction based on Einstein’s equivalence principle.
Led by BGU’s Prof. Ron Folman, the research gives physicists a new way to explore one of science’s biggest questions: how gravity and quantum physics fit together. It hasn’t solved that question—but it opens an exciting new path for investigating it.

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom’s quantum wave so that one part was held in place while the other fell freely under gravity, then re...
