A theory of relativity

The theory of relativity, developed by Albert Einstein, describes how motion and gravity affect time and space. It has two parts: special relativity, which shows that time slows down for objects moving close to light speed, and general relativity, which explains gravity as the curvature of spacetime caused by mass and energy. Essentially, massive objects like planets and stars bend space and time around them, influencing how objects move and how time passes. This theory revolutionized our understanding of the universe, revealing that space and time are interconnected and dynamic, not fixed and absolute.
