Reionization
(cosmology) The epoch of reionization of the Universe, where matter decoupled from energy, and space became transparent to radiation. One of the Ages of the Universe. The cosmic era when ultraviolet radiation of the first (Population III) stars and quasars ionized neutral hydrogen, ending the Cosmic Dark Age(s).
After around 100 million years, the first stars formed; these were likely very massive, luminous, and responsible for the reionization of the Universe. Source: Internet
These massive stars triggered the reionization process and are believed to have created many of the heavy elements in the early Universe, which, through nuclear decay, create lighter elements, allowing the cycle of nucleosynthesis to continue longer. Source: Internet
This implies a period of reionization during which some of the material of the universe was broken into hydrogen ions. Source: Internet
