I was reading an article on Olber's Paradox (why the universe isn't as bright as the sun) and the more I read on it, the more the same question came to mind...
We know the observable universe is approximately 93G LY across and we know the age of the universe is 13.8 B years. We also know that there are galaxies moving away from us faster than the speed of light due to ever-increasing expansion.
If we cannot see these galaxies due to the redshift of their light... how is it that we can see the CMB which is behind them (to our perspective)? Shouldn't it be moving even faster away from us?
If we can see it, why can we not see the galaxies furthest from us?
