Some of the strangest ideas about space — from cosmic sounds to rogue planets — are grounded in real science. Astronomers have detected sound waves rippling through dense galaxy clusters, though at ...

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

The “kitchen triangle” is an important concept for kitchen design, aiming to make it easier for homeowners to use their space efficiently. This theory refers to a kitchen layout that’s comprised of ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

In late winter, the zodiacal light is visible in the evening in the Northern Hemisphere (false dusk) and in the pre-dawn ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...
