A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

An artist's impression of Earth's gravity well. The idea that gravity is the result of the curvature of space-time is a core principle of Einstein's theory of general relativity. An artist's ...

At the close of the same century, this realization was made even more complicated when, by observing distant supernovas as they move away from Earth ... gravity, general relativity, posited by ...

This groundbreaking work redefined gravity as a geometric feature ... on the other side of the black hole." "Einstein's ...

In 2015, a piece of equipment at an observatory in the US moved one quintillionth (10-18) of a meter. This tiny movement was ...

A major breakthrough in theoretical physics might finally unify gravity with the other fundamental forces. This discovery, made by Finnish researchers, opens unprecedented perspectives on the ...

a result that matched Einstein's theory. "Imagine the Earth as if it were immersed in honey," Gravity Probe-B principal investigator Francis Everitt, of Stanford University, said in a NASA ...

In Einstein's universe, however, the direction of the spin axis of Gravity Probe B's gyroscopes should gradually change due to the mass and rotation of Earth. "Imagine the Earth is immersed in ...

This one is particularly special, because it’s so close to Earth and the alignment makes it very beautiful.” Studying the gravitational effects of Einstein ... distorted by gravity as it ...

This one is particularly special, because it's so close to Earth and the alignment makes ... called space-time. Gravity, Einstein discovered, isn't produced by an unseen force but by space-time ...
