Time-traveling Bubbles: Oldest Galaxies Found[2021-02-04]
During the cooling down of the universe after the Big Bang, protons and electrons combined to form neutral hydrogens, which would absorb ultraviolet photons, and thus the universe was in the so-called Cosmic Dark Ages.The universe entered the epoch of reionization (EoR) when First Generation Stars and Galaxies began to form, as the hard ultraviolet photons they emitted ionized the hydrogens, or th... -
