Physicists have experimentally confirmed a strange prediction: the dark “holes” inside light waves can appear to move faster than light itself. But Einstein’s laws still stand as darkness isn’t a ...
A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared to move faster than light itself, darting through a wave field before ...
The universe’s expansion makes cosmic distance far less intuitive than simply measuring how long light has traveled.
Your high school physics teacher wasn't lying—nothing with mass can outrun light. But scientists at Technion just proved that "darkness" itself doesn't follow those rules. They've confirmed that ...
Here is a thought experiment for you: imagine shining a powerful laser at the moon, the beam cutting through space until it lands on its dusty grey surface. Now flick the laser so the spot of light ...
The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...
