There’s a new generation of experiments that may unlock the gravity particle. Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the ...

(via PBS Space Time) Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the elusive graviton—the quantum particle of gravity—whose ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

(via PBS Space Time) To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity. And to do that, most physicists believe we need a ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...
