When the universe first formed, it consisted mainly of hydrogen atoms. Over time, the hydrogen atoms began to collect together to form large balls of hydrogen gas. The hydrogen atoms continued to attract each other, moving closer together. Eventually, pressure and temperature at the center of the cloud of hydrogen became high enough for nuclear fusion to begin. This formed the first generation of stars in the universe.
What caused these early stars to form?
