For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

General relativity explains gravity as the distortion of space-time. Quantum mechanics explains other forces using exchanged "virtual particles." Unifying gravity with quantum mechanics is a major ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

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 ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

Physicist Brian Cox has rarely been shy about his enthusiasm for big, difficult ideas, but his reaction to a recent quantum ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Quantum theory and general relativity will only be unified when theory meets experiment Physics in the 20th century was built on two great revolutions: the general theory of relativity and quantum ...
