Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Isaac Newton lounging beneath an apple tree, suddenly getting bonked on the head by falling fruit, and boom—gravity is ...

When Newton first proposed the law of universal gravitation, it marked the very first time that we realized the same rule governing how objects fell on Earth also governed how they moved and attracted ...

It could rock the very foundations of modern science. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Just four numbers underpin the laws of ...

Researchers used sophisticated computer simulations to devise a test that could answer a burning question in astrophysics: is there really dark matter? Or does Newton's gravitational law need to be ...

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 ...

For many years, physicists have wondered whether a certain well-known exotic material may experience gravitational repulsion from the Earth. That material is antimatter, and physicists at CERN have ...

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity ...
