(via Minute Physics) This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved ...

We've all heard of relativity, but what is it? How does it relate to light and motion? So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion?

The breakthrough could suggest a way to study 'quantum gravity,' the missing link between quantum physics and Einstein's general relativity in the lab. When you purchase through links on our site, we ...

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 ...

Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision Right on time When I was a first-term graduate ...

Teaching relativity to a dog may sound like a hopeless mental exercise, but physics professor Chad Orzel says it actually makes the job of teaching relativity to humans easier. "It makes the whole ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

Pedro Ferreira looks back at how Einstein himself and a panoply of other physicists have framed the theory. Until very recently, relativists were few and often self-taught. General relativity still ...

Taking the class General Relativity and Cosmology in my final year at university certainly made me realize how extraordinary an achievement Einstein's was, but what I recall best is the professor's ...
