Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

The speed of light remains one of physics’ firmest assumptions, but scientists still test whether it ever shifts under ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special theory ...

Albert Einstein's famous relativity quote, "When you are courting a nice girl an hour seems like a second. When you sit on a ...

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 ...

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...

Like Max Planck, Albert Einstein first studied mathematics because he was told that everything interesting in physics had already been discovered. But in 1905, Einstein, a young cleark at the Swiss ...
