Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Among the many functions performed by skeletal muscles, an important one is maintaining our posture. If it weren’t for these muscles, Earth’s gravitational pull may make it difficult for us to stand ...

We explore if there is a true connection between light and gravity. We know that gravity exerts its pull on light, and we have an explanation for why. Actually, we have multiple explanations that all ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. A new discovery suggests ...

"One of the questions I got was how does gravity work, and I was like, 'Oh that's a great question," says Hirotaka Ata, M.D., Ph.D., one of the volunteer scientists. "I talked about how everything has ...

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 ...
