What are Einstein’s field equations? Can they be understood without a physics degree? This book provides the answer. With care and clarity, the author offers scientifically curious readers an accessible path into Einstein’s theories of relativity. Only high school-level knowledge is assumed, making the material approachable for anyone with a strong interest in science. Readers explore both the physical phenomena and the mathematical techniques needed to grasp Einstein’s theory of gravity on a quantitative level. Step by step, the book guides readers toward answers to fundamental questions about General Relativity: How does Einstein’s theory of gravity differ from Newton’s? How can gravitational attraction be described geometrically? How can a black hole “swallow” light?
