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 ...

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

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

For over a century, physicists have been trying to answer one of the most profound questions in science: Can gravity be unified with the quantum world? While the main model describes the ...

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

Gravity is part of our everyday life. Still, the gravitational force remains mysterious: to this day we do not understand whether its ultimate nature is geometrical, as Einstein envisaged, or governed ...

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

Scientists are now developing spinning space stations with artificial gravity that could take astronauts deeper into the ...

On Wednesday (Sept. 27) morning, an international team of physicists reported a major finding about an elusive form of matter known as antimatter. It appears that antimatter responds to gravity the ...
