The Big Bang
Why is the Universe expanding? What is Cosmic Back Ground Radiation (CBR)? There are many questions asked about our Universe, which we know so little about. Scientists, in their attempt to answer these and other confrontations, have found one idea that seems to explain much of what we don't understand: The Big Bang Theory.
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. Instead, the particles were in their free form and were called quarks. 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......
