Big Bang

The Big Bang is a cosmological model associated with the beginning of the universe and forms the basis for the expansion of the universe. According to this theory, the universe began suddenly from a single point of current density and expansion about 13.8 billion years ago.

Following the Big Bang, the universe expanded at great speed and began to cool. In its early moments, the universe was hot, dense and homogeneous. Over time, the universe cooled and density differences emerged. Matter and energy began to combine to form atoms, molecules, galaxies and stars.

The Big Bang model is used to explain the expansion rate of the universe, the age of the universe, and observed phenomena such as the cosmic microwave background radiation. Work is also ongoing to explain the existence of mysterious components that make up the structure of the universe, such as dark matter and dark energy.

This theory is an important basis for understanding the history and evolution of the universe. How the universe took shape after the Big Bang and how it became what it is today is a subject of great interest and research for astronomers and physicists.
