    What is known about how long it took to transition from an opaque universe to the release of the cosmic microwave background?

    The usual publications about the CMB cover that, chances are good tons of websites will also mention it. The CMB light we see mainly comes from a period of ~20,000 years, about 380,000 years after the big bang.
