I get that there are zero optical photons from the CMB, neither should there be as they've been travelling in all directions everywhere for the passed 13.4 billion Earth orbits of our star. But to be enabled to prove the maths is astounding me. I have read a "Briefer history of time" by Stephen Hawkin purely because the maths in the "Brief history..." went over my head. As much of this does. However, I see the value in proving an idea and listen anyway because it is reliable. Thank you Mr. Kendall, your lectures fascinate me all the same.
