Viewers see animations of the universe expanding rapidly in the moments after the Big Bang, as temperatures reached trillions of degrees.

Next, the episode delves into the early universe, when matter and antimatter existed in equal amounts. As matter and antimatter annihilated each other upon contact, only a small amount of matter remained, which eventually formed the galaxies and stars we see today. Viewers learn about the role dark matter played in the formation of the universe, as well as the discovery of cosmic microwave background radiation, which provided evidence for the Big Bang theory.
