Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Measurements of the Cosmic Microwave Background provide robust empirical constraints and thermal history data supporting the standard model of a hot, dense early universe.

The analysis

The claim is specific, scientific, and falsifiable, meeting Step 0 criteria. Papers [3], [5], and [8] discuss CMB measurements and analyses that rely on or confirm standard cosmological models of a hot, dense early universe, while other papers provide supporting context on primordial thermodynamics and Big Bang nucleosynthesis. None of the retrieved papers refute the claim.
