This lesson explores the fundamental questions about the universe, such as its origin, structure, and eventual fate, by examining key astronomical phenomena and theoretical frameworks. It delves into the roles of dark matter, dark energy, and cosmic inflation in shaping the cosmos, providing insights into the ongoing quest to understand the universe's deepest mysteries.

The solar system serves as a microcosm of the universe, revealing the intricate relationships between celestial bodies and the forces that govern their movements. Each planet and moon tells a unique story of formation and evolution, inviting deeper reflection on our place in the cosmos.

Stars are the building blocks of galaxies, illuminating the vastness of space and time while serving as cosmic laboratories for the fundamental processes of nature. The life cycles of these stellar giants mirror the evolution of the universe itself, highlighting the interconnectedness of all matter.

The quest to understand cosmic origins challenges our perceptions of reality, inviting us to ponder profound questions about existence and the nature of time. Each theory offers a different lens through which to view the universe's birth, shaping our understanding of everything that followed.

Dark matter and dark energy constitute the vast majority of the universe, yet remain elusive and enigmatic, pushing the boundaries of our scientific understanding. Their existence compels us to rethink the fundamental principles of physics and the structure of the cosmos.
