A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared to move faster than light itself, darting through a wave field before ...

Here's what you'll learn when you read this story: Although people often say nothing travels faster than the speed of light, this cosmic speed limit only pertains to particles with information or mass ...

All light that we see consists of electromagnetic waves, which travel at the ultimate speed limit of the universe: the speed ...

Just over four light-years away, the Alpha Centauri system holds the closest worlds beyond our own that might support life.

A research group from the Technion-Israel Institute of Technology reports in Nature an unprecedented achievement in electron microscopy: the direct measurement of "dark points" within light waves. By ...

These theoretical particles ignore the basic structure of cause and effect. If scientists ever prove they’re real, tachyons would shatter our understanding of reality. But relativity also tells us ...

The reliable manipulation of the speed at which light travels through objects could have valuable implications for the development of various advanced technologies, including high-speed communication ...

In late 2020, physicist Harold “Sonny” White, PhD, research director of the nonprofit Limitless Space Institute, noticed something peculiar—and familiar—in a circular pattern of data plots generated ...

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 ...
