Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string ...

Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model ...

A complete theory of quantum gravity remains one of the biggest challenges in modern science. Recent research ... However, the model also predicts a small, positive cosmological constant ...

General relativity is an astonishingly beautiful theory, and grappling with why it disagrees with quantum mechanics is a joy, ...

NASA and partners are building the first quantum gravity sensor for space, a breakthrough instrument that uses ultra-cold ...

"We could determine the mass of the Himalayas using atoms," Jason Hyon, chief technologist for Earth Science at NASA's Jet ...

All the fundamental forces are thought to be carried by a particle, but a new mathematical model suggests gravity may be a striking exception. Building on a decades-old idea, researchers have ...

To address these inconsistencies, the researchers turned to string theory, one of the leading candidates for a quantum theory of gravity. Unlike the Standard Model, which treats elementary ...
