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 ...

It’s a basic principle of cosmology that our place and time in the universe are not special: that, for years and light-years forward and backward, the basic laws and constants of nature stay the same.

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 ...

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

Through extremely high precision measurements of a pulsar orbiting a white dwarf star, astronomers have found that the gravitational constant, which dictates the force of gravity, is "reassuringly ...

A scene from the movie Gravity. In real life, gravity is always bringing us down—particularly scientists who attempt to measure gravitational force. Try as they might, physicists cannot agree on a ...

Astronomers have produced the best constraint ever of the gravitational constant measured outside of our Solar System. Gravity, one of the four fundamental forces of nature, appears reassuringly ...

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 ...

The theoretical framework underlying gravitational waves may have to be revamped to account for dark energy and the acceleration of the expansion of the universe. That’s the conclusion of researchers ...

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...
