Legacy on Instagram: "No problem! Here’s the information about the Schwarzschild Radius and Black Holes ⚫📏 🔹 What is the Schwarzschild Radius? • The Schwarzschild radius defines the size of the event horizon of a black hole, the boundary beyond which nothing, not even light, can escape. It is named after the physicist Karl Schwarzschild, who first derived it in 1916 🔭 • The Schwarzschild radius R_s is calculated by the formula: R_s = 2GM/c² where: - G is the gravitational constant, - M is the
