A clear look at how physics defines gravity, from Newton’s force-based model to Einstein’s view of curved spacetime, and why the distinction matters in modern science.

Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general ...

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Physicists are facing a paradoxical situation. On one hand, they are searching for a fifth fundamental force that could ...

Quantum physical experiments exploring the motion of macroscopic or heavy bodies under gravitational forces require protection from any environmental noise and highly efficient sensing. An ideal ...

The proposed BMV experiment could test whether gravity is quantum, a breakthrough that may lead to quantum computers and ...

The physics of neutron stars is a remarkable combination of Einstein’s theory of general relativity and nuclear physics. Their interiors harbour extreme matter that cannot be probed in the laboratory.
