What would it really take to travel at or beyond the speed of light? In this video, we break down the hard physics Hollywood ...

The most distant galaxies in this deep field image from the James Webb Space Telescope appear as small, faint dots—and are receding from us faster than the speed of light due to cosmic expansion. If ...

Time would pass differently on Earth for travelers moving at light speed, with thousands of years potentially elapsing while ...

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 ...

Brian Haidet] published on his AlphaPhoenix channel a laser beam recorded at 2 billion frames per second. Well, sort of. The catch? It’s only a one pixel by one pixel video, but he repeats ...

Researchers at Tsinghua University developed the Optical Feature Extraction Engine (OFE2), an optical engine that processes ...

When I was a teenager, I was—shockingly, I know—deeply nerdy. At a science-fiction convention, I bought a button that read, “186,282 miles/second: Not just a good idea, it’s the law.” It was poking ...

Researchers have found a way to mimic lightspeed when photographing an object. The method involves stitching together many thin “slices” of light reflecting off the object. Photography—itself a ...

Researchers have developed an optical computing system that performs feature extraction for quantitative trading with ...

McLaren Formula 1 team principal Andrea Stella is confident Oscar Piastri can brush off a difficult United States Grand Prix ...
