A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ongoing quest for quantum gravity. These findings, which involve the behavior ...

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. A new discovery suggests ...

For the first time, scientists have observed antimatter particles falling under the effect of gravity—a phenomenon that was long theorized but never before seen. The results suggest that antimatter ...
