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 ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

For astronauts to go on long missions to the moon or Mars, they need a refrigerator. But today’s fridges aren’t designed to work in zero gravity or upside down if oriented that way when a spacecraft ...

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 ...
