  • @xkguy

    Max Planck tried using a silver cavity. He got no blackbody radiation until he added a small carbon particle. He thought it acted as a catalyst. Dr Robitaille has shown that it was the graphite lattice that was actually required to produce blackbody radiation. This has led to his theory that the sun also has a lattice in the form of planar liquid metallic hydrogen (type 1) on its surface. Interesting ...right?

  • @ericwalters3426
    @ericwalters3426 Год назад

    How can something absorbe, and emitt at the same time? Thats like having a magnet thats both positive and negative on the same side. Even electrons are positive, or negative, they cant be both st once. I guess like you say they dont exist in nature. I guess its really all theoretical then. Not sure what brought me to look into this subject, i think i was looking into scalar wave radiation, and i was trying to understand the different ways scalar wave radiation works.

    Why was it called ' Ultraviolet Catastrophe ' ?

    • @TheSecretsoftheUniverse
      @TheSecretsoftheUniverse  4 года назад +1

      At high frequencies, at UV and beyond, the integral blows up. That's why it is known as the ultraviolet catastrophe. This term collectively signifies that Rayleigh Jeans law gives absurd results at high frequencies such as at the UV frequency.
