How was the universe formed?

The formation of the universe is a complex and still not fully understood process. According to the Big Bang theory, the universe began as a singularity, a point of infinite density and temperature, around 13.8 billion years ago. This singularity rapidly expanded and cooled, leading to the formation of matter and energy. Over time, these particles began to clump together due to gravity, forming stars, galaxies, and eventually planets. The universe continues to expand and evolve to this day.

The prevailing theory for the formation of the universe is the Big Bang theory. According to the theory, the universe began about 13.8 billion years ago as an incredibly hot and dense singularity. In a fraction of a second, the singularity expanded rapidly, creating a hot and dense soup of fundamental particles. Over time, these particles cooled and combined to form atoms, which then formed stars and galaxies. As the universe continued to expand and cool, it eventually evolved into the cosmos we observe today.
