The speed of light is often used to describe anything that is ultrafast, rendering it impossible for humans to capture its motion. Now, researchers are able to capture the elusive object in slow ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

The “slow motion” modes on modern smartphones crank up the speed of video recording so that when it’s played back at regular speed, the motion you see on the screen is slowed down. It’s a neat feature ...

They recreate how a camera would see objects traveling at 99.9% of the speed of light, revealing surprising relativistic illusions.

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, ...

Light is the fastest-moving thing in the universe. So what would happen if the speed of light were much, much slower? In a vacuum, the speed of light is about 186,000 miles per second (300,000 ...
