Theory of Relativity (Albert Einstein)
Albert Einstein's Theory of Relativity fundamentally changed our understanding of space, time, and gravity. It describes how objects move through space and time, especially at high speeds or in strong gravitational fields. Special relativity shows that time can slow down and lengths contract when objects approach the speed of light, depending on the observer’s perspective. General relativity explains gravity not as a force, but as the curvature of spacetime caused by mass and energy. Massive objects like planets and stars warp spacetime, guiding the motion of other objects. Together, these theories provide a comprehensive framework for understanding the universe’s structure and behavior.
