A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...

A new study has revealed that gravity's effect on Earth is constantly shaping the surface of our planet. When our planet formed, it did so by pulling dust and rock toward its gravitational field. As ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...
