A new space device called GIRO could transform how we study planets and other celestial bodies. Compact and precise, this ...

For example, as masses get smaller, so do their gravitational fields, making it even more difficult to differentiate them from ambient vibrations or noise.

As reported in Nature, researchers have measured the gravitational pull of two gold spheres about 2 millimeters (0.079 inches) in diameter with a mass of around 90 milligrams (0.003 ounces).

For example, the gravitational field strength on Earth is 10 N/kg whereas on Jupiter it is 24.7 N/kg. This means that a mass of 50 kg will weigh just over double on Jupiter than it would on Earth.

The Laser Interferometer Gravitational-wave Observatory (LIGO) is no stranger to making history and breaking records. In 2015 ...

Eventually, physicists’ hope to measure gravitational fields in a quantum state, thus reconciling the fact that general relativity, the theory that best explains gravity, cannot be explained in ...

A new method to analyze gravitational-wave data could transform how we study some of the universe's most extreme events—black ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. The gravitational field on ...

Every assessment to date has been conducted in rather weak gravitational fields. To put general relativity to its greatest test, we need to see whether it holds up where gravity is extremely strong.

For example, the Sun is 330,000 times the mass of the Earth. As a result, ... The new theory also incorporates a G-field, or gravitational field.
