The Core Idea: Gravity = Curved Spacetime Einstein’s revolutionary insight (1915) was that gravity isn’t a force like Newton thought – it’s the curvature of spacetime itself caused by mass and energy. The Two Key Principles: The Einstein Field Equations (Simplified) The full mathematical form looks complex:Gμν = 8πG/c4 Tμν But here’s what it means…
