Thanks for the equations and please forgive my ignorance, but I don't know what values to plug in for the variables / constants in the sinh equation...
Could you let me know what the CBR wavelength would have been, 1, 3, and 6 billion years ago and please show the math so I can then plug in...
hello,
I'm wondering how to calculate, even approximately for the relatively mature universe, what the CBR wavelength was as a function of age of the universe. I get that the CBR began during recombination, though have read different values for the black body temperature at that...
