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 ...

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

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 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 ...

Robert Zubrin’s Nuclear Salt Water Rocket (NSWR) design is a rocket that uses known physics and engineering . There are versions that could reach 7-8% of light speed. The use of low grade uranium ...

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 ...
