What does the Big Bang theory explain?

• A. The formation of stars in galaxies
• B. The creation of the universe
• C. The life cycle of an average star
• D. The clustering of galaxies

Answer: (B)

The Big Bang theory explains the creation of the universe, detailing how it began as an incredibly hot and dense point approximately 13.8 billion years ago. This theory describes the rapid expansion that followed, leading to the cooling and formation of matter, which eventually led to the creation of atoms, stars, galaxies, and the large-scale structure of the universe we observe today. It provides a comprehensive framework for understanding the initial conditions of the universe and how it evolved over time. In contrast, the formation of stars in galaxies primarily focuses on processes that occur after the universe's creation. The life cycle of an average star involves nuclear fusion and other stellar phenomena that occur within a star's lifecycle, assuming the existence of galaxies and the universe itself. The clustering of galaxies refers to the gravitational interactions and structures that arise in the universe well after the initial Big Bang event, focusing on the organization of matter rather than its origin. Thus, the Big Bang theory is fundamentally about the creation of the universe itself.
