Albert Einstein, one of the most celebrated modern scientists, proposed the revolutionary theory of special relativity more than a century ago. This theory forms the basis of most of what we ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When it comes to a science like physics, theoretical expectations must ...

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 ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

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

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

In the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, researchers report that Einstein's theory of general relativity holds up, at least for ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you were a physicist in the early 20th century, there would have ...

Researchers at Osaka University demonstrate the relativistic contraction of an electric field produced by fast-moving charged particles, as predicted by Einstein’s theory, which can help improve ...
