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, ...

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.

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 ...

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 ...
