early universe

(from the Big Bang to recombination)

The term early universe is used to refer to the universe from the Big Bang through some of its early phases. Early stages include inflation and the synthesis of protons and neutrons (both taking place well within the first second), and Big Bang nucleosynthesis (within the first few minutes).

The phrase may refer to just these very early stages, or to mean its history through recombination (about 377,000 years after the Big Bang), or even through the epoch of reionization (millions to a billion years after).
