•Astrology has been rejected by the scientific community as having no explanatory power for describing the universe.
•What I will state is somewhat condensed and very much over simplified.
The very beginning of this universe was marked by rapid expansion and cooling. As the infant universe expanded and cooled different windows opened for the formation of different sub atomic particles, the building blocks of matter, namely quarks and electrons. Further expansional cooling allowed the quarks to embrace one another forming larger sub atomic particles, protons and neutrons. More cooling allowed the positively charged protons and the negatively charged electrons to slow enough to a point where they could no longer resist the electrostatic attraction and hydrogen atoms were born.
As the universe continued to expand and cool the hydrogen began to clump and the first stars were born. Stars are the ultimate alchemists. Thermonuclear fusion in the core of stars takes the hydrogen and creates larger elements up to iron-sized. The death of the largest of stars is a violent explosion known as a supernova. Conditions are so extreme that even larger elements can be created.
