3. Theory of Relativity: in physics, the problem of how physical laws and measurements change when considered by observers in various states of motion. Thus, relativity is concerned with measurements made by different observers moving relatively to one another. In classical physics it was assumed that all observers anywhere in the universe, whether moving or not, obtained identical measurements of space and time intervals. According to relativity theory, this is not so, but their results depend on their relative motions.
