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’ ...

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 ...

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 argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are both interested and skeptical. Isaac Newton was never entirely happy with his ...

According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers ...
