Homework Help: Era of recombination - temperature variant

  1. Jan 2, 2009 #1
    1. The problem statement, all variables and given/known data
    When radiatio was first emmited 300,000 years after the big bang during the so-called era of recombination, it was in the visible region of the spectrum. What does this data tell scientist about the temperature variant of the early universe

    2. Relevant equations

    3. The attempt at a solution

    well aparently the temperature remained pretty much constant, but how do you tell that?
