Physics | After about 14 seconds after "the beginning" of the universe, the temperature dropped to 3,000,000,000 K. When neutrons and protons collided, it was to hot for them to stick together. Since deuterium (a proton and a neutron) could not be formed, there were no large molecules. As the universe cooled down, (see Universe Expansion) the nucleons (protons and neutrons) were able to stick together. Then, deuterium was able to form into helium. * Hot Universe* Cool Universe.
