Super nerdy post of the week: Audio from friction-less fluid offers a cool beat

Okay, this is a bit out there, but if you love science, you’ll find much to love here. Scientists at MIT have been student the viscosity of fluids. Whenever any fluid flows, there’s resistance to that motion on a molecular level. A “perfect fluid” is one that has almost no resistance friction.

Fine. So what?

These white-coated boffins are interested in such fluids because it can explain the viscosity in the cores of neutron stars, the ultra-ultra-ultra-dense remnants of supernova explosions. Hey, I told you this was nerdy.

Part of their experiments include sending sound ways through a gas of particles call fermions to determine how the sound was diffused, which in turn determined the viscosity of the material. The result was this audio recording that mimics what we might hear in the core of a neutron star. Or something like that.

Anyone want to sample this for something?
