The universe comes with a built‑in speed cap, a hard limit that shapes everything from how stars shine to how cause and effect unfold. That limit is usually described as the speed of light, yet the ...

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 ...

If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of ...

“It’s neither possible nor survivable to travel near the speed of light relative to our good old Earth,” says Gerd Kortemeyer, emeritus associate professor of physics at Michigan State University.

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

Researchers have demonstrated single-shot tensor computing at the speed of light – a remarkable step towards next-generation Artificial General Intelligence hardware powered by optical computation ...
