Scientists were able to record its sound by creating a perfect fluid with quantum-level friction. The flow of this perfect fluid is found only in the plasma of the universe and in the nuclei of neutron stars.
How does “perfect flow” sound to you? Could it be the sound of water falling from a waterfall or the rustle of water pouring from the pitcher into a glass? Although the answer to this question varies from person to person, it is difficult to say that the sound it produces is also very different, as there is only one definition of perfect flow for science.
According to physicists, perfect flow is a flow with little friction or viscosity, as allowed by the laws of quantum mechanics. What is such a perfect flow can be seen in nature; rare enough to be seen only in the nuclei of neutron stars or in plasmas formed when the universe was “young”.
Scientists from the Massachusetts Institute of Technology (MIT) managed to create a perfect liquid in a laboratory setting and recorded the “flow” sound of this liquid and shared it on SoundCloud. We can guarantee that it has a very different sound from a waterfall.
Shared sound recording is a product of sound waves generated during a controlled flow with subatomic particles known as fermions. Scientists analyzed thousands of sound waves to measure the rate at which sound, related to the viscosity or internal friction of the material, disperses through the gas.
As a result of the analysis, surprisingly, it was found that the sound diffusion created by the mass of fermions of the liquid formed was low enough to be defined by a quantity of “quantum” friction. This determination revealed that farm gas behaves like a perfect fluid and is universal.
As you can imagine, scientists did not create this fluid just for a sound recording. Thanks to the fluid in question, they can be used to model plasma viscosity in the early universe and quantum friction within neutron stars. Although there are differences between the fermion gas used by scientists for the flux in question and the speed of sound in the neutron star, Martin Zwierlein, a physics professor at MIT, said he predicted that the resonant frequencies in the star would be similar. to gas ones.
