Relativistic

Relativistic describes anything related to the theory of relativity, particularly Einstein's special and general relativity. In physics, relativistic effects arise when objects move at substantial fractions of the speed of light or when strong gravitational fields influence spacetime. The term contrasts with nonrelativistic models that assume absolute time and space and ignore such effects.

Special relativity, formulated by Albert Einstein in 1905, establishes the constancy of the speed of light

Relativistic physics is essential in particle physics and astrophysics. In particle accelerators, particles reach speeds where

In practical terms, relativistic corrections are routinely applied in technologies such as global positioning systems, which
