The Big Bang Theory is a scientific explanation for the origin of the universe. It suggests that about 13.8 billion years ago, the universe began as a singularity with infinite density and temperature, and has since expanded and cooled to its current state.
The Big Bang Theory was first proposed by Belgian priest and physicist Georges Lemaître in the early 20th century. It was later supported by observations made by American astronomer Edwin Hubble, who found evidence of an expanding universe and cosmic microwave background radiation.
Some key pieces of evidence that support the Big Bang Theory include the expansion of the universe, the abundance of light elements, and the cosmic microwave background radiation. Additionally, the theory accurately predicts the observed distribution of galaxies and the large-scale structure of the universe.
According to the Big Bang Theory, the universe underwent a period of rapid expansion known as inflation in the first fraction of a second after the initial singularity. As the universe expanded and cooled, elementary particles began to form and eventually combine to form atoms. This process continued for millions of years until the first stars and galaxies formed.
The current state of the universe is constantly expanding and cooling. Recent observations have shown that the expansion of the universe is actually accelerating, which is believed to be caused by dark energy. The universe is also made up of about 70% dark energy, 25% dark matter, and only about 5% ordinary matter.
