The Big Bang Theory is a scientific model that explains the origins of the universe. It suggests that the universe began as a small, incredibly hot and dense point about 13.8 billion years ago. This point, called a singularity, contained all the matter and energy that would eventually form the entire universe.
At the moment of the Big Bang, the universe began to rapidly expand and cool down. Within fractions of a second, elementary particles like protons and neutrons formed. These particles then combined to form the first atoms, primarily hydrogen and helium.
Over time, gravity caused these atoms to come together and form stars and galaxies. As these objects continued to evolve, new elements formed through processes like nuclear fusion and supernovae explosions.
Today, the universe continues to expand and evolve. The Big Bang Theory is supported by a wide range of evidence, including cosmic background radiation, the abundance of light elements, and observations of distant galaxies.
