Use left and right arrow keys to seek audio. Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this ...

A RATHER glib distinction is often made between the two pillars of modern physics. Quantum mechanics is the physics of the very small, while general relativity is the physics of the very large. That’s ...

The theory of general relativity upended the world of physics and even its author resisted accepting a bizarre phenomenon the math said had to exist.

This article is from Proof PositiveSign up today and read it first. Last week I explained how Albert Einstein’s special theory of relativity makes time travel into the future possible—and how varied ...

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

The weak-equivalence principle is integral to general relativity, so these test results offer yet more support for a core theory of our universe. In 1916, Albert Einstein dared to declare that Isaac ...

Albert Einstein’s general theory of relativity is one of the towering achievements of 20th-century physics. Published in 1916, it explains that what we perceive as the force of gravity in fact arises ...

(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 ...
