Answer:
The theory of relativity was published by Albert Einstein in 1915.
Albert Einstein, a renowned physicist, developed the theory of relativity, which revolutionized our understanding of space, time, and gravity. In 1915, Einstein published his general theory of relativity, which built upon his earlier special theory of relativity published in 1905.
Einstein's theory of relativity introduced groundbreaking concepts, such as the equivalence of mass and energy (E = mc^2) and the curvature of spacetime by mass and energy. It provided a new framework for understanding the behavior of objects moving at high speeds or in the presence of strong gravitational fields.
The publication of the theory of relativity in 1915 by Albert Einstein marked a significant milestone in the field of physics and had a profound impact on our understanding of the universe.
