Add Yahoo as a preferred source to see more of our stories on Google. The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

A confident attempt to dismiss gravity as a hoax quickly turns into an unexpected lesson in physics. As equations, calculations, and basic scientific principles are put to the test, the argument ...

A small causal diamond used as a tiny local laboratory for deriving gravity from thermal physics. Heat flows in and out across the light-like boundaries of the diamond, allowing the authors to ask ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

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 ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...
