Scientists confirm the incredible existence of ‘second sound’

MIT physicists capture the first sounds of heat “sloshing” in a superfluid

For the first time, MIT physicists have captured direct images of “second sound,” the movement of heat sloshing back and forth within a superfluid. The results will expand scientists’ understanding of heat flow in superconductors and neutron stars.

Scientists reveal heat can behave like sound in superfluid

Scientists have revealed that in some exotic states of matter, heat can behave like sound and bounce back and forth. The phenomenon is not new and is known as “second sound.” But the scientists at MIT have for the first time captured the images of the ‘second sound’. The images show how heat can move like sound waves when generated within a superfluid, a state of matter where atoms flow without any friction. The physicists found that heat and m…

Scientists confirm the incredible existence of ‘second sound’

Although this phenomenon has been observed before, it’s never been imaged.

Scientists Confirm the Incredible Existence of ‘Second Sound’

Here’s visible proof for the first time ever.

First-ever images of heat 'sloshing' like sound waves captured by MIT in a superfluid

The experiments mark the first time scientists have been able to image second sound directly and the pure motion of heat in a superfluid quantum gas.
