Question

Quizplus · Accepted Answer

During the nuclear epoch, the universe was hot and dense enough for deuterium and helium to form through nuclear fusion reactions. However, heavier elements were not yet produced at this time. The nuclear epoch occurred during the formation of deuterium and helium, two of the lightest elements in the periodic table. This period occurred shortly after the Big Bang, when the universe was hot and dense enough for nuclear fusion reactions to occur. As protons and neutrons combined to form these elements, a large amount of energy was released, which eventually led to the formation of stars and galaxies. While all known elements were eventually formed through processes such as stellar nucleosynthesis, they were not all created during the nuclear epoch.
