The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

In the quest to measure the fundamental constant that governs the strength of gravity, scientists are getting a wiggle on. Using a pair of meter-long, vibrating metal beams, scientists have made a new ...

A painting of Sir Isaac Newton by Sir Godfrey Kneller, dated to 1689. A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the ...

We now have the most precise estimates for the strength of gravity yet. Two experiments measuring the tiny gravitational attraction between objects in a lab have measured Newton’s gravitational ...
