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

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 ...

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. When you purchase through ...

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 ...
