Metrics of Relativity

Metrics of relativity refer to the ways physicists measure and understand the effects of space and time in different reference frames, especially when objects move at high speeds or strong gravitational fields are present. They include quantities like spacetime intervals, which combine distance and time; proper time, which is experienced by a moving clock; and invariants, quantities that remain the same regardless of the observer’s motion. These metrics help describe how measurements such as length, time, and gravity vary from one observer to another, forming the mathematical foundation of Einstein’s theory of relativity.
