A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

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 ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...

In context: Antimatter is a substance composed of antiparticles with an opposite electric charge compared to the corresponding particles in "ordinary" matter. Despite its opposite nature, antimatter ...

Sam Baron receives funding from the Australian Research Council. Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...
