The Great Singularity began to break up. Space and the different elements began to be formed. With this first breath a countervailing rhythm of arithmetic expansion and geometric contraction began. We are still in the early stages of the expansion of the Universe where all Galaxies are receding from each other at the speed of light. This is the exhalation of Brahman.
Expansion occurs as arithmetical electromagnetic growth.
At the same time the force of contraction grows with the geometrical growth of gravitation. Under one theory the expansion of matter and energy away from the center explosion point is preceded by black spheres. Where they meet, the Galaxies originate fractally. Billions of galaxies have been and will continue to be formed as the Universe expands. Within each galaxy billions of stars then form.
