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 ...

To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.

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 ...
