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 ...
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 ...
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 ...
About 85 percent of the matter in the universe is thought to be dark matter, yet there is still no confirmed direct detection of any dark matter particle. Ground-based detectors, space-based ...

A region beneath Antarctica where Earth’s gravitational pull is measurably weaker than anywhere else on the planet has persisted for roughly 70 million years, according to new research that traces 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 — ...
Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...
