What Happened After the Lights Came On in the Universe?
Posted by Guy Pirro on 9/20/2016 5:44 PM
An experiment to explore the aftermath of the cosmic dawn, when stars and galaxies first lit up the universe, is underway at the University of California - Berkeley. According to Robert Sanders of UC - Berkeley, the HERA collaboration will explore the billion year period after hydrogen gas collapsed into the first stars (perhaps 100 million years after the Big Bang) igniting stars and galaxies throughout the universe. These first brilliant objects flooded the universe with ultraviolet light that split or ionized all the hydrogen atoms between galaxies into protons and electrons to create the universe that we see today. That's the theory, anyway. HERA hopes for the first time to observe this key cosmic milestone and then map the evolution of re-ionization to about 1 billion years after the Big Bang.
