Support for the Big Bang theory infers that all galaxies are moving away from the Milky Way, suggesting that the universe originated from a single point. Another fact supporting this theory is the abundance and composition of elements within the observable Universe. The ratio of hydrogen, helium and other elements suggests that the entire Universe was once very dense, causing it to fuse hydrogen into lighter elements as though it were the core of a single star. The Big Bang theory also involves a tremendous release of radiation billions of years ago, still able to be detected and measured as of 2015.

The Big Bang theory states that the Universe expanded from a point of very high temperature and density. This theory also provide a comprehensive explanation for a wide range of phenomena which includes the presence of light elements, large scale structures throughout the observable Universe and a scientific principle known as Hubble's Law. The Big Bang theory was first proposed in 1927 by Georges Lemaître.
