An explosion of incomprehensible speed was the beginning of our known Universe and existence. At that time matter as small as the head of a pin inflated to become larger than the visible Universe of today in less then one millisecond. The newly born Universe cooled very quickly and continued to grow. Still, the heat was too great for normal elementary particles like protons and neutrons to be bound together.

These quarks and the massive amount of radiation released form the explosion made up most of the Universe in the first microsecond.
Within the quarks, matter and......
