The next major era occurs when photons no longer are able to ionize atoms as soon as they form. This allows ... hydrogen and helium atoms to form, taking out the free electrons. This "era of recombination", about a million years after the big bang, frees the photons because their former interactions with electrons no longer occur (the electrons are "recombined" in atoms).
