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 ...

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 ...

Earth and other terrestrial planets probably use their gravitational forces to tear apart asteroids ― but this creates more streams of smaller asteroids. When you purchase through links on our site, ...

Imagine for a moment that Earth suddenly shrank to the size of the Moon, while the Moon expanded to the size of Earth. How would life on our planet change? Could humans survive this dramatic cosmic ...
