Gravity is the force of attraction between two objects. Its effects play an interesting role between a giant planet such as Jupiter or Saturn and their numerous moons — for instance, the Galilean ...

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 is a pretty awesome fundamental force. If it wasn't for the Earth's comfortable 1 g, which causes objects to fall towards the Earth at a speed of 9.8 m/s², we'd all float off into space. And ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest numbers to nail down.

There’s one force whose effects are so deeply entrenched in our everyday lives that we probably don’t think much about it at all: gravity. Gravity is the force that causes attraction between masses.

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

In February 2016, an international team of physicists announced the first direct observation of gravitational waves. The waves had been produced by the gigantic collision of a pair of black holes, ...
