Experiment at Paul Scherrer Institute generates a directed muonium beam via superfluid helium ejection to test the ...

Examining Einstein’s equivalence principle The atom chip used in the quantum Galileo interferometer experiment. In the ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at quantum scales.

A new experiment found that a falling quantum wave behaves just as Einstein’s equivalence principle predicts. The result ...

Since Galileo Galilei and Newton, the assumption is valid that inert and heavy mass are equivalent. This is, however, questioned by new physical theories such as the String theory. Now, the ...

Gravity is the OG of the forces of Nature. Historically it was the first to be discovered and described scientifically, yet it’s the most challenging to study. Even though gravity governs the orbits ...

At the heart of Einstein’s theory of gravity (general relativity) is the equivalence principle. The equivalence principle says that there is no difference between being stationary and subject to ...

The GRAVITY Collaboration, a team of researchers at several renowned institutes including the Max Planck Institute, LESIA Paris Observatory and the European Southern Observatory, has recently tested ...

Superfluid helium has produced a narrow muonium beam, opening a path to test whether exotic particles fall like ordinary ...

Galileo’s most famous experiment has taken a trip to outer space. The result? Einstein was right yet again. The experiment confirms a tenet of Einstein’s theory of gravity with greater precision than ...
