In the young Universe neutrons which had not found their way into alpha particles soon broke up into a proton, an electron and an antineutrino. This is an example of beta radioactivity. Something similar happens in some large nuclei such as thorium.
This happened about 12 minutes after the Big Bang. After this the Universe consisted of protons, electrons, alphas and radiation. |
