A black hole is a region of spacetime where gravity is so intense that nothing, no matter how much energy it has, can escape. Inside the event horizon, gravity supersedes all other forces of nature.

Neutron stars aren’t just notable for the valuable elements they create, though. They’re also a dream come true for physicists. From their crushing gravity to the universe’s strongest magnetic fields, ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

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.

Black holes are mysterious cosmic objects with gravity which are so strong that even light cannot escape. They form when massive stars collapse under their own gravity creating a dense point called a ...
