Earth’s gravitational force, g, has been known for centuries. But the exact value of G, the universal gravitational constant, ...
Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Can you please explain to us how awesome this is, and what you hope the ...
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 ...
After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest ...
Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...

Laser light and the quantum nature of gravity: Proposed experiment could measure graviton energy exchange
When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...
An artist's impression of the quantum experiment. (Courtesy: University of Southampton) The first technique capable of measuring the pull of gravity on a particle just microns in diameter could aid ...
The European Space Agency is making a risky manoeuvre with one of its most sophisticated satellites, but by lowering GOCE's orbit deeper into the high-drag outer reaches of the atmosphere scientists ...
