Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

A spacecraft traveling at 99 percent the speed of light toward Alpha Centauri would cross 4.3 light-years in what feels like months to its crew, while decades tick by on Earth. That asymmetry is not ...

SCIENTISTS who threw down the gauntlet to physics by reporting particles that broke the Universe's speed limit say they're revisiting their contested experiment. "The new test began two or three days ...

In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating the structure of time and space as we know it. But what if this cornerstone ...

In 1999, a Danish physicist named Lene Hau did the unthinkable. She slowed the speed of light. It was a remarkable move that completely changed our idea of universal constants. Since then, Hau has ...

In late 2020, physicist Harold “Sonny” White, PhD, research director of the nonprofit Limitless Space Institute, noticed something peculiar—and familiar—in a circular pattern of data plots generated ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...
