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 ...

Gravity is the force with which we’re most familiar. It’s what’s keeping you on the planet, even as you’re reading this. Despite gravity feeling deeply intertwined with our daily lives, scientists are ...

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 ...

A multi-institutional team of physicists is proposing an experiment to test whether gravity behaves as a quantum entity when measured. They published a description of their experiment in the journal ...

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 ...

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 ...

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.
