Einstein’s famous tenet of special relativity — that time slows down on a moving clock — has been verified 10 times more precisely than ever before. The result comes from physicists in Germany and ...

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

Scientists studying radiation from a distant gamma-ray burst have found that the speed of light does not vary with wavelength down to distance scales below that of the Planck length. They say that ...

In his discussion of accelerated motion on page 60 of "The Meaning of Relativity," Albert Einstein made an approximation that allowed him to develop the theory of relativity further. Einstein ...

Faster-than-light travel is impossible according to our current understanding of physics. Wormholes are theoretically possible but require unstable, exotic matter to stabilize. Generation ships are a ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. Yesterday, I wrote about the core concepts needed to understand quantum ...

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 ...

Ever wonder what it would look like to travel at the speed of light? The folks at MIT’s education games lab have created a simple 3D simulator to teach the masses about the counterintuitive principles ...

A central idea of physics is that reference frames don't change fundamental laws. It shouldn't matter where you observe an event or how fast you are moving, the laws of physics should remain the same ...

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 ...
