Currently, the force of gravity can’t be explained in terms of quantum physics, but being able to measure its effects on smaller and smaller scales could unlock its secrets and perhaps reveal ...

This larger gravitational force between two bodies relies on something called the gravitational constant that is used to calculate the relative gravitational force between two objects.

The movie Gravity had everyone spellbound with its gripping portrayal of spacewalks and the perils astronauts encounter ...

Quantum particles can feel the influence of gravitational fields they never touch Scientists reveal that the Aharonov-Bohm effect also applies to gravity ...

A new theory suggests gravitational waves – rather than hypothetical particles ... All scientists can do at this point is come up with theories that fit the physics of the Universe we do observe.

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers ...

Explaining gravity’s relative feebleness is a profound challenge for physics, and an essential milestone on the road to a unified theory of all four forces.
