The Big Bang theory suggests that the universe originated from a singularity, an extremely hot and dense point, around 13.8 billion years ago. In an event known as the Big Bang, the universe rapidly expanded and cooled, leading to the formation of galaxies, stars, and other celestial objects. Over time, gravity caused matter to come together and form larger structures, ultimately resulting in the diverse and complex universe we observe today.

The Big Bang theory posits that the universe began as a hot, dense point and expanded rapidly. This expansion led to the formation of galaxies, stars, and other celestial objects, evolving over billions of years. Gravity played a crucial role in the clumping of matter and the creation of the diverse universe we observe today.
The Big Bang theory proposes that the universe began as a singularity, an extremely hot and dense state, approximately 13.8 billion years ago. It suggests that the universe has been expanding ever since, with all matter and energy originating from this initial event. Over time, galaxies, stars, and other cosmic structures have formed through the gravitational attraction of matter.
