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 ...

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 ...

The long-range influence of gravity, despite its comparative weakness, stems from its inverse-square law, where its flux remains constant over arbitrary distances due to the compensatory increase 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, ...

Of the four fundamental forces, gravity is the one we’re most familiar with in our everyday lives, but perhaps surprisingly, it’s the weakest and hardest to measure here on Earth. Now, physicists in ...

In the effort to unify the gravitational theory of general relativity with the quantum theory of the very small theoretical physicists explore a lot of wild ideas. One of these is the idea of higher ...

At the end of the 18th century, the British scientist Henry Cavendish measured the force of gravity between two objects for the first time in a laboratory. The objects in question were lead balls, one ...
