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 ...

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 ...

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 ...

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 ...

Using two separate tests, scientists have measured a new value for a fundamental natural quantity – G, the gravitational constant – that is slightly higher than previous experiments. Though the result ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

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 ...

Despite intensified efforts, measurements of the gravitational constant continue to fail to converge, as Terry Quinn explains. The 1986 CODATA (Committee on Data for Science and Technology) evaluation ...
