Isn't there a "date" missing for the "border-line" between "Neutral Hydrogen Forms" and "Modern Universe" ?
Here: [www.ctc.cam.ac.uk/outreach/origins/big_bang_three.php] this border seems to be "Earliest visible galaxies" estimated by 700 million years.
Isn't this also the above discussed "border-line" ? -- and should be added there in the diagram?
