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 ...

So, the experiment is designed to determine whether quantum entanglement occurs in the pair during freefall, when the force of the gravity between the diamonds is the only way that they interact.

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 ...

A new experiment will test the notion that gravity, one of the fundamental forces in the physical world, relies upon quantum physics to work. If so, it would further indicate the centrality of quantum ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Is gravity a result of differences in informational density? Or is this theory too far out there to address all the issues present in modern physics? Here, we take a look at a recent proposal that ...
