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…

Introduction Black holes—cosmic monsters where gravity crushes matter into oblivion—challenge our understanding of physics. At their edges (event horizons) and cores (singularities), Einstein’s general relativity (governing gravity) collides with quantum mechanics (ruling the subatomic). This conflict hints at a deeper theory: quantum gravity. Here’s how black holes probe the quantum universe: 1. The Black Hole…
