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 ...

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 ...

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 ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...

Physicists have used the quantum nature of matter to obtain a highly precise value for the universal gravitational constant, the 'big G' that appears in Isaac Newton's law of how gravity pulls ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Can you please explain to us how awesome this is, and what you hope the ...

Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...

A team of engineers studying the 500-year-old, backward writings of Leonardo da Vinci have found evidence that the Italian polymath was working out gravity a century before its foundations were ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...
