The big bang theory proposes that the universe originated from a singularity, a point of infinite density and temperature. Approximately 13.8 billion years ago, this singularity began to rapidly expand and cool, leading to the formation of matter and energy. Over time, the universe continued to expand and evolve, with matter clumping together to form galaxies, stars, and eventually planets. The big bang theory is supported by various pieces of evidence, such as the observation of cosmic microwave background radiation and the redshift of galaxies, which indicate an expanding universe.

The big bang theory explains that the universe originated from a singularity, a point of infinite density and temperature. Around 13.7 billion years ago, this singularity exploded and started expanding rapidly, creating space, time, and matter. As the universe expanded, matter cooled down and eventually formed galaxies, stars, and planets. This theory is supported by various pieces of evidence, such as the observed expansion of the universe, the cosmic microwave background radiation, and the abundance of light elements.

The big bang theory states that the universe began as a singularity, a point of infinite density and temperature, around 13.8 billion years ago. This singularity rapidly expanded, leading to the formation of matter and energy. Over time, galaxies, stars, and planets began to form through the force of gravity. The big bang theory also explains the expansion of the universe, as observed through redshift, and the presence of cosmic microwave background radiation, which is considered as a remnant of the fiery hot early universe.
