Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

In 2015, the general theory of relativity will be 100 years old. In November 2015, Albert Einstein gave weekly lectures to the Prussian Academy of Sciences in which he set out the fundamental field ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

One of the goals of modern physics is to determine the underlying rules that govern our reality. Indeed, one of the wonders of the universe is that just a few rules seem to describe many aspects of ...

In 1915, Germany introduced chlorine gas into the ongoing horror that was World War I. It was the war to end all wars, bringing devastation that would scar a generation. But one man’s mind continued ...

In August 2014 a rocket launched the fifth and sixth satellites of the Galileo global navigation system, the European Union's $11-billion answer to the U.S.'s GPS. But celebration turned to ...

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.

Everyone knows Albert Einstein was a genius, but can you explain what he’s famous for? Arguably his foremost theory, his general theory of relativity, turns 100 years old this week. It was actually ...

Wormholes, warp speed, space-time anomalies — science fiction wouldn't be the same without Albert Einstein's general theory of relativity. And in the real world, we would probably also notice a few ...
