A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

WASHINGTON, Dec. 16, 2025 — Helium leaks are hard to detect. Helium is odorless, colorless, tasteless, and does not react with other chemical substances. Not only can we not see or smell it, but ...

Sound has a speed limit. Under normal circumstances, its waves can travel no faster than about 36 kilometers per second, physicists propose October 9 in Science Advances. Sound zips along at different ...

Above is a video by the physicist, YouTuber and quantum cartographer Dominic Walliman, who describes a map of quantum physics that he has created. The map introduces quantum mechanics by providing ...

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.
