CMB emitted ~380,000 yrs after Big Bang, redshifted ~13.8 billion years; also internal consistency with stated 13.8 Gyr age.
Beforeenormously redshifted by 13.4 billion years of cosmic expansion
Afterenormously redshifted by 13.8 billion years of cosmic expansion
Why: The CMB was emitted approximately 380,000 years after the Big Bang and has been redshifted over roughly 13.8 billion years of cosmic expansion, consistent with the universe's age stated elsewhere in the article. The prior 13.4 billion year figure was internally inconsistent.
