Time crystals sound like something out of a SciFi movie, but they are real and easier to see than ever.

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.

A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

Explore 25 science experiments that defied the laws of physics, revealing mind-bending phenomena that challenge intuition.

Some asteroids can barely hold it together. Rather than solid lumps of rock, ‘rubble pile’ asteroids are loose collections of material, which can split apart as they rotate (SN: 3/16/20). To ...

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.

The terahertz quantum cascade laser on its mounting. Credit: University of Leeds Lasers that switch on and off billions of times per second are the backbone of optical communications networks, but ...
