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 ...

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 ...

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 ...

There are several ways that surface gravity on Earth could change. We wouldn’t like most of them. If a mini black hole collided with Earth and didn’t pass straight through, it would sink to the planet ...
