BUT: It is not as much about the origin of the universe as it is about the development of the universe over time.
BUT: The origin of the universe was not an explosion of matter into already existing space. Before the Big Bang, there was nothing.
The four pillars of the Big Bang Theory succinctly in the January 2001 edition of Scientific American (the whole issue was about cosmology and is worth reading!):
– Red shift.
– Cosmic microwave background radiation.
– Hydrogen ± 75% and Helium ± 25%
– Detailed observations of the size, shape and distribution of galaxies and quasars is in agreement with the current state of the BBT
1965 two researchers Arno Penzias and Robert Wilson, verified the existence of Cosmic microwave background radiation. These are the ‘stretched out’ electromagnetic waves that were left over from the inflation period right at the beginning, when matter and anti-matter were annihilating each other in bursts of light.
