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 ...

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 ...

Some of the first experiments in space dealt with gravity and weightlessness. They were somewhat simple studies to test the new environment. Alan Shepard was the first man to hit a golf ball on the ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

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’ ...

Artistic representation of the implemented photonic experiment in which entanglement between the polarizations of single photons is mediated by the independent degree of freedom of the photon path.

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 ...
