The BIG Bang Theory

Picture
What exactly is the BIG Bang Theory? Well, the BIG Bang Theory is the origin of the universe. In 1927, a Roman Priest calculated the Friedman Solution on his own, and suggested that the universe was expanding.Through the early 1960's and 70's steady state physics tried to explain the BIG Bang Theory, but it was clear that they couldnt explain it.Our universe sprang into existance around 13.7 billion years ago.
The universe went from very small, to very dense, to very hot, to the size as we see it today. In 1929, Edwin Hubble found that the distance of the galaxies and the redshift in the galaxies light, was when the theory was supported. There are still a lot of questions about the BIG Bang Theory...but they probably can't be answered because nobody knows what caused, started, or how to explain the BIG Bang Theory.
