The document discusses the origin of the universe according to the Big Bang theory. It states that the Big Bang occurred approximately 13.8 billion years ago as the single, extremely hot and dense point which exploded, causing the observable universe to expand and cool. As the universe expanded, primordial atoms formed and the leftover radiation from the early hot dense period became cosmic microwave background radiation, which is detectable and provides evidence supporting the Big Bang model. The future of the universe remains uncertain but may expand indefinitely and grow cooler.
