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 ...

A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics. Reading time 3 minutes Despite keeping us ...

The Sun is not nailed to the center of the solar system. It moves, wobbles, and traces a small loop through space, tugged by ...

What is gravity without mass? Both Newton's revolutionary laws describing its universal effect and Einstein's proposal of a dimpled spacetime, we've thought of gravity as exclusively within the domain ...

The “gravity hole” formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our ...

An international collaboration led by scientists mainly at Tokyo University of Agriculture and Technology (TUAT) , Japan, has found that bone and muscle mass are regulated by the altered gravity. The ...

What is mass? It seems like a synonym for weight, but that isn’t quite right. Weight is how we measure the pressure that gravity exerts upon things. But mass? Mass is the actual presence of an item — ...

Researchers from NASA's Jet Propulsion Laboratory in Southern California, along with academic institutions and private businesses, are developing the first space-based quantum gravity sensor.

Gravitational anomalies detected by NASA and the German Aerospace Center’s GRACE satellites confused scientists for years. Here’s what happened.

THE fans roar into life, pumping air upwards at 260 kilometres per hour. Decked out in a baggy blue jumpsuit, red helmet and plastic goggles, Claudia de Rham steps forward into a glass chamber and… ...
