WebThe era of nuclei: Matter is a hot plasma of H and He nuclei, mostly; lasts 300,000 yr, until T = 3000 K and protons and electrons stick together. The Formation of Atoms Decoupling: The era of nuclei ends at about 380,000 yr, when neutral atoms form and most of the matter does not affect photons anymore; matter becomes transparent to visible light.

In cosmology, recombination refers to the epoch during which charged electrons and protons first became bound to form electrically neutral hydrogen atoms. Recombination occurred about 370,000 years after the Big Bang (at a redshift of z = 1100 ). The word "recombination" is misleading, since the Big Bang theory doesn't posit that protons and electrons had been combined before, but the name exists for historical reasons since it was named before the Big Bang hypothesis became t… The Era of Atoms (380,000 years – 1 billion years or so) began as the universe finally cooled and expanded enough for the nuclei to capture free electrons, forming fully-fledged, neutral atoms.
