This course is a comprehensive exploration of Albert Einstein’s most profound legacy: the reimagining of the universe as a geometric masterpiece. We begin by tracing the historic shift from Isaac Newton’s "invisible force" of gravity to Einstein’s radical realization that space and time are not separate entities, but are woven together into a single, four-dimensional fabric called spacetime. You will discover how mass and energy actually warp this fabric, turning gravity from a mysterious pull into a physical property of the world around us.

The curriculum then dives into the mind-bending reality of Gravitational Time Dilation, proving that your sense of time is dictated by your location in a gravitational well. You will explore the "living mathematics" of Riemannian geometry, where we define geodesics—the straightest possible paths in a curved world—to understand why planets orbit and apples fall. We simplify the intimidating Einstein Field Equations, breaking down the symbols that serve as the universal rulebook: telling mass-energy how to curve spacetime, and curved spacetime how to move mass-energy.

Finally, we venture into the most extreme corners of the cosmos, from the "blunder" of the Cosmological Constant that now explains the accelerating expansion of our universe to the terrifying reality of Black Holes. You will stand at the edge of the Event Horizon and Peer into the Singularity, where our current equations fail and the search for a "Theory of Everything" begins.
