“Equipped with the right amount of dark matter, computer simulations reveal the formation of large regions of filamentary web-like networks of dark matter and hydrogen gas. At the nodes of these filaments, hydrogen gas coalesces, similar to water droplets on a spiderweb after a rainfall. It is in these regions, called protogalaxies, where hydrogen gas gets gravitationally concentrated into the first stars. Through nuclear fusion, the immense gravitational pressure in the star converts hydrogen into heavier elements. These first-generation stars can be up to one million times more massive than our sun. The first generation of stars lives on the order of one hundred million years and eventually dies through supernova explosions.”
