Researchers propose how the universe became filled with light
Iowa City IA (SPX) Aug 31, 2017
Soon after the Big Bang, the universe went completely dark. The intense, seminal event that created the cosmos churned up so much hot, thick gas that light was completely trapped. Much later--perhaps as many as one billion years after the Big Bang--the universe expanded, became more transparent, and eventually filled up with galaxies, planets, stars, and other objects that give off visible light. That's the universe we know today. How it emerged from the cosmic dark ages to a clearer, light-filled ... read more
