Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers ...

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 ...

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 ...
