The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Of the four fundamental forces, gravity is the one we’re most familiar with in our everyday lives, but perhaps surprisingly, it’s the weakest and hardest to measure here on Earth. Now, physicists in ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

An astrophysicist has shown that gravity may be able to exist without mass, a theory that suggests dark matter may not be necessary to explain phenomena observed in our universe. Dark matter is a ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An image of a black hole surrounded by matter. Does the secret of quantum gravity lie around ...

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. In a moment over 100 years in the making, the 2017 Nobel Prize in ...

Gravity is one of the four fundamental forces in the universe, alongside electromagnetism and the strong and weak nuclear forces. Despite being all-pervasive and important for keeping our feet from ...

Gravitational physicists explore the implications of the general theory of relativity, in which gravitation is a consequence of the curvature of space and time. This curvature thus controls the motion ...
