It takes light a single day to travel 16 billion miles. The Voyager 1 probe will need a little longer, just 49 years.

I'll be honest: I didn't know that an iPhone was able to do a lidar scan. (The iPhone 12 Pro, 13 Pro, and iPad Pro can all do it.) When I found out that my phone could, I became obsessed with scanning ...

The effect, first predicted over 60 years ago and regarding objects traveling near the speed of light, has been lent support ...

A small but incredibly fast unwanted guest is about to swing past Earth at the speed of light. Yeah, this is the tiniest ...

The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

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

We throw around terms like “light year” and “faster than light travel” frequently. But to really understand the scale it helps to feel how fast the speed of light is. The flight simulation video below ...

Here, a calcite crystal is struck with a laser operating at 445 nanometers, fluorescing and displaying properties of birefringence. Unlike the standard picture of light breaking into individual ...

Congratulations on noticing an effect called superluminal expansion, a phenomenon we see in a light echo. The echo appears to us to expand at many times the speed of light, seemingly violating the ...

Last Word is New Scientist’s long-running series in which readers give scientific answers to each other’s questions, ranging ...

If a very large disc on a frictionless, horizontal spindle were gradually rotated faster and faster, what would happen as the ...

A new architecture replaces traditional bottlenecks with a passive, single-shot light-speed operation that could become the ...
