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 ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

Though there is an overwhelming amount of information floating around out there about the theory of relativity in all her guises, I was stumped last week when my eight year old nephew asked me to ...

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 ...

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 ...

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 ...

What if the Big Bang didn't begin with a singularity? This point of infinite density, which so divides physicists, could be avoided. A new approach to quantum gravity suggests that the universe may ...

A recent theory of gravity has stimulated intense debate and many explorations of its implications. There is, however, an example that served as a model for Hořava’s theory. The example, due to ...
