Quelle est la théorie du big bang ?<end_of_turn>
<start_of_turn>model
The big bang theory is the leading scientific explanation for the origin of the universe. According to this theory, the universe originated approximately 13.8 billion years ago from an extremely hot and dense singularity. As the universe expanded and cooled, atoms, then stars, galaxies, and solar systems formed. This theory is supported by extensive observational evidence, such as cosmic background radiation, the expansion of the universe, and the abundance of light elements.<end_of_turn><eos>
