The Big Bang theory is the leading explanation of how the Universe began, suggesting it started from an infinitely hot and dense point about 13.8 billion years ago and has been expanding ever since. This expansion is supported by observations such as galaxies moving away from us, cosmic microwave background radiation, and the abundance of light elements like hydrogen and helium predicted by Big Bang Nucleosynthesis [1][3][4][6].
