The proposed BMV experiment could test whether gravity is quantum, a breakthrough that may lead to quantum computers and ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever ...

A multi-institutional team of physicists is proposing an experiment to test whether gravity behaves as a quantum entity when measured. They published a description of their experiment in the journal ...

Post-spacetime physics refers to the idea that our familiar 4D spacetime is not fundamental but emerges from deeper ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ongoing quest for quantum gravity. These findings, which involve the behavior ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

The Cold Atom Lab is a facility for the study of ultra-cold quantum gases in the microgravity environment of the ...
