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 ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...

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 ...

For many single-celled organisms living in water, the force is always against them. The classic example is the slipper-shaped paramecium, which consistently swims harder going up than going down, just ...

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, ...

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 ...

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 ...

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 ...
