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

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and ...

A clear look at how physics defines gravity, from Newton’s force-based model to Einstein’s view of curved spacetime, and why ...

Dr Charles Buhler takes people through his lab in a new video. He explains more about how they developed and detected a new force from large electrostatic pressure differences. They claim this force ...

Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps our feet on the ground and holds planets in orbit. The pursuit was more or ...

Newton’s Law of Gravity just survived its biggest cosmic test. Scientists studied nearly 686,000 galaxies spread across 7 billion light-years. The result surprised even modern cosmologists. Gravity ...

About a century ago, Albert Einstein amazed the world with his groundbreaking theory of relativity, and ever since he shared this profound understanding of gravity and spacetime, physicists everywhere ...

Big G, gravity, is the oldest fundamental constant in physics and the least clearly defined. One scientist has spent a decade ...
