−enormously redshifted by 13.4 billion years of cosmic expansion
+enormously redshifted by 13.8 billion years of cosmic expansion
Why this is better
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.
