The most widely accepted scientific theory for the beginning of the universe is the Big Bang Theory. While there is no definitive answer as to how the universe began, it can be concluded that this theory is the most credible. It is said to have occurred approximately 13.7 billion years ago. Scientists have dissected this theory and have concluded that the universe must have originated from a single point of infinite density and finite time that began to expand. From this initial bang the universe has continued to expand

The initial bang in this theory was extremely hot. It was so hot, that scientists and astronomers believed that there had to be left over heat and radiation somewhere within the universe to prove it. While studies on the Big Bang Theory began in the 1910s, the study of heat and radiation were not tangible yet. It wasn’t until 1965 when Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin CMB, or Cosmic Microwave Background radiation. “Cosmic Microwave Radiation is radiation that fills the universe and can be detected in every direction. Created shortly after the universe came into being in the Big Bang, the CMB represents the earliest radiation at can be detected.” In detail, Monroe W. Strickberger in his book “Evolution,” states that “Although visible energy seems to be radiating primarily from the galaxies and their stars, there is evidence from radio telescopes that a background of fairly uniform low-temperature radiation, pervades the entire universe. This black body radiation is predictable if the original big bang occurred between 10 to 20 billion years ago and began with an initial temperature of about 10^32 degrees Kelvin. As time went on and the universe expanded, its temperature decreased, reached the present 2.726K.” One theory that was used to try and debunk the Big Bang Theory was the “Steady State Theory” which basically said that the universe had always existed and that it was always expanding at the level of density. But this theory was no longer valid after left over radiation was found, because this left over radiation means that the density at the time of creation must have been a lot greater than the density of the expanding universe
