At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Gravity is the most familiar of nature’s forces. It keeps our feet planted on the ground and dictates the movements of ...

Gravity, despite its pervasive influence, is the weakest fundamental force, easily overcome even by simple actions like lifting a pencil. While achieving and maintaining orbit requires significant ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...
