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 ...

The proposed BMV experiment could test whether gravity is quantum, a breakthrough that may lead to quantum computers and ...

Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps our feet on the ground and holds planets in orbit. Related video above: ...

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 ...

We are all bobbing in a sea of ripples in space-time, called gravitational waves, reverberating through the fabric of the universe, scientists announced on Wednesday. Those ripples are probably the ...

According to the general theory of relativity’s weak equivalence principle, all masses behave identically under the influence of gravity. Although well-tested for matter, it has remained unclear ...
