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 ...

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 ...

Gravity, one of the four fundamental forces of nature, appears reassuringly constant across the universe, according to a decades-long study of a distant pulsar. This research helps to answer a ...

Physics is based on the assumption that certain fundamental features of nature are constant. Some constants are considered to be more fundamental than others, including the velocity of light c and the ...
