The document summarizes the key events and developments in the prevailing scientific theory of the origins and evolution of the universe known as the Big Bang theory. It describes how observations from the early 20th century led scientists including Lemaitre and Gamow to propose that the universe expanded from an initial extremely dense and hot state around 13.7 billion years ago. Subsequent discoveries refined this theory, showing how stars, galaxies and larger structures in the universe formed over billions of years from early quantum fluctuations in the aftermath of the Big Bang.
