At present scientists think that at the highest energies and earliest moments in time, all the fundamental forces may have existed as a single unified force. As the universe cooled just one microsecond after the Big Bang, it underwent a “phase transition” that transformed or “broke” the unified electromagnetic and weak forces into the distinct forces observed today.
