21 cm radiation

  1. Mar 2, 2006 #1
    I do not necessarly see what this has to do with a confirmation of the big bank theory. On the surface I would view this as a confirmation of QMs. It simple says that ocassionally you have enough KE to flip a spin of from the basic ground state. Maybe the "intensity" of the radiation might indicate a hotter spot, because you have more flips. Likewise if you were cooler you would statistically expect less flips and therefore less intensity. But the wavelength is always going to be exactly 21 cm, the spin flip energy.

    Now if you tell me that the this 21 radiation has a uniforms intensity no matter where in space I look, then maybe we can talk big bang, as the whole universe blinks into existence everywhere so the intensity is exactly the same.

    Please help my thinking.
