Ever wondered what gravity really is? Is it a force, or is there more to it than we know? In this video, we break down the theory of general relativity, revealing how mass and energy bend the fabric ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. ... with this curvature being produced by the mass-energy and momentum content of the spacetime.

Here we explore what the theory of general relativity is and how it affects space-time. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works ...

In General Relativity, it isn't the net force acting on an object that determines how it moves and accelerates, but rather the curvature of space (and spacetime) itself.

General relativity characterizes gravity not as an innate force acting on objects but rather the consequence of space-time's curvature. (Imagine a marble rolling down the incline created by the ...

Einstein published a new theory of gravity—the theory of general relativity—in 1915. It would transform our understanding of physics forever. But it’s far from perfect.

Dong and Song proved a conjecture that was formulated in 2001 by the mathematicians Gerhard Huisken and Tom Ilmanen.The conjecture states that as the mass of a space approaches zero, so too must its ...

In 1907, Albert Einstein had his “happiest thought” — people in free fall do not feel their own weight. This simple idea laid the foundation for his general theory of relativity, which ...
