Observations of supermassive black holes at the centers of galaxies point to a likely source of dark energy—the 'missing' 70% of the universe. The measurements from ancient and dormant galaxies show ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. A new discovery suggests ...

Several new projects that aim to exploit the Earth’s gravity for power hint at how electric vehicles could unlock otherwise impossible ways of generating energy. They include trains across the ...

Black holes embody the ultimate abyss. They are the most powerful sources of gravity in the universe, capable of dramatically distorting space and time around them. When disturbed, they begin to "ring ...

Gravity energy storage, whereby engineers harness the energy in gravitational forces by connecting the momentum generated to the electric grid, is a relatively new technology that could serve to ...

There was a secret inside the envelope in the hands of Stephan Schlamminger, one of the world’s leading experts in experimental tests of gravity. He appeared to be on the verge of opening the envelope ...

In a Swiss valley, an unusual multi-armed crane lifts two 35-ton concrete blocks high into the air. The blocks delicately inch their way up the blue steel frame of the crane, where they hang suspended ...
