Part 5. The Size of the Universe Our beautiful spiral 'Milky Way' embraces the solar system and Earth. Though it is a massive structure holding over 400 billion stars, even our galaxy is merely a tiny speck of dust compared to the vastness of the entire cosmos. Just how incredibly large and wide is the universe? How far does the observable universe extend? Part 6. Supernovas Like all things that exist, stars are born and eventually die. When a star reaches the end of its lifespan, it explodes, releasing an immense amount of energy. During this explosive death, elements essential for creating life are scattered across space like seeds. Without these elements, no living creature on Earth could have been born. Therefore, every living being is fundamentally a 'descendant of a supernova.' Part 7. Black Holes A terrifying celestial body that devours everything around it, even light itself—the black hole. Once you cross the boundary surrounding a black hole, no entity can ever return. What lies beyond this event horizon remains completely beyond our current understanding of physics. Let's take a look into the mouth of this terrifying cosmic monster.
