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 ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Physicists think the answer lies with dark matter, an invisible form of matter that accounts for that extra gravity they’re observing. University of Washington physicist Alvaro Chavarria helped build ...

Astronomers are announcing today that the precise gravity field of the lunar far side and the global lunar topography map were obtained by KAGUYA spacecraft. The report is being presented by Dr. Sho ...

Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a property that emerges from some deeper physical interaction. This emergent ...
