For 100 years, Albert Einstein's general theory of relativity has survived just about every test that physicists have thrown at it. Announced in November 1915, the famous scientist's field equations ...

Over the weekend, for some odd reason (probably LIGO-related), political blogger Kevin Drum decided to take on General Relativity arguing that despite its intimidating reputation, it's not that ...

General relativity is a profoundly complex mathematical theory, but its description of black holes is amazingly simple. A stable black hole can be described by just three properties: its mass, its ...

Scientists may be celebrating the 100th anniversary of Albert Einstein's general theory of relativity, but there was also a death in 1915. It was one of the many deaths of simple and intuitive physics ...

Why can't anything travel faster than the speed of light? Do black holes really suck? And why is the universe expanding? These are just a few of the questions author and astrophysicist Jeffrey Bennett ...

Understand Einstein’s General Relativity with a clear and easy-to-follow explanation that breaks down complex ideas like spacetime, gravity, and curvature in simple terms. This video uses intuitive ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. It's difficult to appreciate how revolutionary of a transformation it ...
