Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

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 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 ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

In the last episode of Cosmos: A Spacetime Odyssey (which you can watch online), the show was trying to make a case for dark matter. Here is what Neil DeGrasse Tyson said about orbiting objects. "In ...

Using a high-powered electromagnet, Brown University physicists Karine Guevorkian and James Valles have created a topsy-turvy world for the single-celled paramecium. They have managed to increase, ...

Your weight changes on other planets and moons due to different gravitational pulls. Weight is how much gravity pulls on you; mass (amount of matter) stays the same. Newton's Law of Gravitation ...

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 ...
