Abstract

Not long after the big bang — a mere 370,000 years later— the universe entered what astronomers now call the dark ages. The cosmos had yet to see the light of stars and galaxies; in fact, a cloak of hydrogen haze smothered almost any photon that might have tried to illuminate the infant universe.
