''Long ago, millions of years before the first star sparked to life, the entire universe was a sea of darkness.
Beginning about 400,000 years after the Big Bang and lasting hundreds of millions of years, this so-called dark age of the universe marked the last time when empty space really was empty; no planets, no suns, no galaxies, no life — just a fog of hydrogen atoms forged by the Big Bang and left to slosh through the darkness.''
