  1. Sep 12, 2022 · Relativity is the study of how observers in different reference frames measure the same event. Modern relativity is divided into two parts. Special relativity deals with observers in uniform (unaccelerated) motion, whereas general relativity includes accelerated relative motion and gravity.

  2. The theory is based on two fundamental principles: Relativity: The laws of physics do not change. Even for objects moving at inertial, constant speed frames of reference. Speed of light: It is the ...

  5. The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity.
