Suddenly, the Singularity began expanding. It was filled homogeneously with a high-energy density. The incredibly high temperatures and pressure gave rise to rapid expansion and cooling where the phase transition that caused for the separation of forces also led to a period where the universe grew exponentially. Temperatures were so high that the random motions of particles occurred at relativistic speeds causing particle–antiparticle pairs to be continuously created and destroyed in collisions, which is believed to have led to the predominance of matter over antimatter.

As the universe continued to decrease in density and temperature, the energy of each particle began to decrease until the fundamental forces of physics and elementary particles changed into their present form.

Mass annihilation of proton-antiproton and neutron-anitneutron pairs occurred, immediately followed by the annihilation of electrons and positrons. After these annihilations, the remaining protons, neutrons and electrons were no longer moving relativistically and the energy density of the universe was dominated by photons – or light.

Electrons combined with hydrogen nuclei and developed into gas clouds, then stars and planets. Two realms came into existence, Niflheim, and Muspelheim. Niflheim was a dark and cold place with only ice, frost, and fog. Muspelheim consisted of fire, lava, and smoke.

There was a great darkness because no sun or moon or stars shone. The Great Spirit dwelled far above in the upper realm. One day the Great Spirit called to his daughter and told her to go into the world of darkness. The woman fell to earth with light emanating from her. A flock of swans flew upward and allowed Sky Woman to rest upon their backs. With great care, they placed her upon the newly formed earth created by the great turtle where Sky Woman gave birth to Good and Evil.
