Although it’s since been superseded by Einstein’s theory of general relativity, Newton’s law of universal gravitation still holds pretty well as an explanation for the large-scale structure and ...

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 ...

In 1915, Einstein’s theory of General Relativity unified space and time, revealing that mass and energy can warp spacetime.

An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The finding challenges Newton's laws of gravity, the researchers write in their ...

Given a particle in Euclidean space, a central force is a force that points toward or away from the origin and depends only on the particle’s distance from the origin. If the particle’s position at ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The idea of gravity as we know it has been around for a long time ...

Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...

An uneven distribution of stars in several nearby clusters may offer evidence of MOND – a controversial theory of gravity that disputes Newton and rejects the existence of dark matter. When you ...

A groundbreaking study, based on observations from the European Space Agency’s billion-pixel Gaia space telescope, has revealed a “gravitational anomaly” that challenges our fundamental understanding ...
