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 ...

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 ...

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 ...

The measurement of the Newtonian gravitational constant, G, remains one of the most challenging pursuits in experimental physics. A variety of techniques have been devised over the past two centuries, ...

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 ...

Ten years after the first gravitational wave detection, a new suite of instruments has captured ringing signals before and ...

Analyzing ripples in the fabric of space and time created by pairs of dead stars may soon solve a cosmic mystery surrounding how quickly the universe is expanding — if scientists are lucky. That's the ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...
