    this is literally the only helpful video about superfluids on youtube.

      LaLakrs Yes, it is. I find another video, but is too old and it isn´t good. guava.physics.uiuc.edu/~nigel/courses/569/video/

      True. But I'm not surprised that a person who received a Noble Price for his work on Bose-Einstein condensates can explain the entire shebang in 10 minutes. What a brilliant man.

    I should have subscribed much sooner. These are very stimulating topics, and he is a brilliant mind to describe them

    I got slightly triggered hearing a thick German accent saying, "If all the people marching lockstep, there is no friction.." "marching in lockstep, being in one wave.." hahaha. Great explanation for a layman like myself.

    How are their spin up spin down fermion pairings in a superfluid? Does a magnetic field need to be present? What and about the nmv or the phase?

      Helium-4 consists of two protons, two neutrons and two electrons. They are all in pairs and hence a boson

    Is superfluidity enabled by "spooky action at a distance?" That is, entanglement? All the particles entangled in one shared quantum state which ignores locality?

    • @faiselbutt2944
      @faiselbutt2944 5 років тому

      You are thinking about the EPR paradox where entangled particles are separated by large distances in order to test whether measuring one's quantum state affects the other.

    So is a superfluid "neutronic"?

    • @r.b.ratieta6111
      @r.b.ratieta6111 4 місяці тому

      And superconductivity "electron-ic"?
      I wonder if there's someway to combine the two? Use superconductivity to power a machine or apparatus that will manage a superfluid?

    I hate regular cold/iced coffee. I can't even imagine how terrible superfluid coffee would be... Anyways, lame jokes aside, I really enjoy these videos; you do an excellent job making such extreme states more accessible and understandable :)

      it would run back up your throat and start coating your entire body, and probably suffocate you,

    Superfluidity is near, "Condensate of Universe"/zero point/absolute zero/apex of Aethers Dielectric energy Hyperboloid. Between Space and Counterspace.

    Science should be for the benefit of all the world. So why not say it in plain English? Superfluids are frictionless and can be in perpetual motion. Bosons can share the same space. That means you can have an infinite amount of Bosons (like light) in a singularity. This should blow your mind.

    Aether's vortices are fermions.
    Aether's hyperboloids are bosons.

    Space is fluid.... Dark matter

      the vaccum is a superfluid. notice how in a vacuum, the momentum of movement is maintained, just like in superfluids.
      this is also the reason why you can not ever reach absolute zero. the particle is just a standing wave, so removing its movement would be to make the particle just vacuum again.
      Notice how mathematically, particles are supposed to disappear when they reach absolute zero. this property is in itself proof of particles being purely mechanical superfluidic vacuum waves.
      and dark matter is just unstable vaccum waves becoming matter for a short duration. they lock into each other and produce gravity, being are not stable. its really the same thing as zero point or vaccuum energy, its just electromagnetic vaccum waves with wave lengths that can not form stable matter.
