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 ...

Cooling metal bars to near absolute zero, suspending microscopic gold beads, or searching for signs that gravity might be quantum: meet the scientists hunting for gravity's elusive nature ...

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 ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

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’ ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

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 ...
