The Big Bang theory is the leading explanation about how the universe began. At its simplest, it talks about the universe as we know it starting with a small singularity, then inflating over the next 13.8 billion years to the cosmos that we know today. Key points include: 1. The universe was once in an extremely hot and dense state which expanded rapidly. 2. This expansion caused the universe to cool and resulted in its current continuously expanding state. 3. It provides a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background radiation, and the large-scale structure of the universe.
