/ˌɹɛɫətɪˈvɪstɪk/

Definition

adj. describing a situation where things are judged based on the specific circumstances or the person's own point of view. In physics, it refers to ideas that change depending on how fast you are moving.

adj. relating to or based on a system of thought in which all truths are relative to the observer or the situation. In physics, it describes the theory of relativity, where measurements of space and time depend on the relative velocity of the observer.

Examples

“The philosopher argued that moral judgments are relativistic, varying significantly between different cultures and historical periods.”

“In a relativistic framework, the concept of absolute time is replaced by a four-dimensional spacetime continuum where the passage of time depends on the observer's relative motion.”
