Что такое вообще Рени зация? Те, кто всё-таки позволяют себе поверить в устоявшуюся сейчас концепцию большого взрыва, они знают, что примерно через 400.000 лет, чуть меньше, после самого этого непонятного события во Вселенной образовались нейтральные атомы из отдельных заряженных частиц.

Из вот этого океана протонов, которые были в горячей такой плазме до момента остывания, образовались атомы нейтрального водорода. В основном водорода, примерно там на 80%. Это был как раз момент, когда освободилось излучение, которые мы сейчас наблюдаем в виде реликтового излучения.

Считается, что примерно спустя приблизительно 100 миллионов лет после большого взрыва начали образовываться первые звёзды.
