Everyone loves “break the record” stories—until physics shows up with a hard rule. The speed of light isn’t just fast, it’s ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the ...

On one hand, the speed of light is just a number: 299,792,458 meters per second. And on the other, it’s one of the most important constants that appears in nature and defines the relationship of ...

Scientists captured the first images of the Terrell-Penrose effect, showing objects near light speed appear rotated rather than compressed in photos.

That's one-tenth the speed of light, according to a study published in Physical Review Letters. The discovery could reveal brand new laws of physics, one expert said. Scientists have calculated a ...

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light moves through space at a constant speed has supported some of physics’ most ...

Let’s explore how constant this speed of light fundamental constant really is. One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can ...

The method involves stitching together many thin “slices” of light reflecting off an object.

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 ...
