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 ...

NASA is calling on college undergraduates interested in performing reduced gravity experiments onboard the agency’s “Weightless Wonder” aircraft to submit their proposals by Monday, Oct. 30. The ...

For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself.

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.

WEST LAFAYETTE, Ind. — After a decade of preparation and two years of active experiments in space, a facility that Purdue University and NASA’s Glenn Research Center in Cleveland designed, built and ...

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 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 ...

Free teacher resource for primary science. In a practical investigation, Mwaksy and Greg look at how unsupported objects fall ...

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 ...
