Albert Einstein's theory of relativity reshaped how we understand space, time, gravity and the universe itself.Albert Einstein's theory of relativity reshaped how we understand space, time, gravity and the universe itself. This book, generated by artificial intelligence, offers a clear and structured introduction to both special and general relativity, without requiring a background in physics or advanced mathematics. You will learn how Einstein arrived at his ideas, why the speed of light plays such a central role, and how concepts such as time dilation, curved spacetime and gravitational waves fit together. The book also places the theory in its historical context and touches on its influence on modern science and technology, including GPS systems. Written in accessible language, this guide is intended for curious readers who want a solid grounding in one of the most important scientific theories of the twentieth century.Albert Einstein's theory of relativity reshaped how we understand space, time, gravity and the universe itself.
