A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

While the electromagnetic, weak, and strong forces are described by the Standard Model of particle physics, gravity remains an outlier—resisting efforts to be fully explained by quantum theory.

A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established requirements for a robust unified ...

Gravimeters can measure the change in g (the acceleration due to gravity) as it varies over time at a single site because of the relative movement of the Sun and the Moon. This variation is called ...

One of the big ideas in physics is that forces change the motion of an object. If you apply a constant, continuous force to an object—and there is no counterforce like wind drag—that object ...

as it collapsed under the pull of gravity, somehow dodged the formation of a singularity and instead bounced into a period of expansion. Physicists who are developing bounce theories often work in the ...
