general theory of relativity
Definition
Noun: - A theory of gravitation developed by Albert Einstein, which is a generalization of his special theory of relativity. It describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass and energy. Its foundation is the principle of equivalence.
Usage
- The term is used as a proper noun to refer specifically to Einstein's geometric theory of gravity. It is often used in scientific, academic, and educational contexts.
- It is frequently contrasted with Newton's law of universal gravitation and with the special theory of relativity.
Examples
- Noun:
- Einstein's general theory of relativity predicted the bending of light by gravity.
- The general theory of relativity has passed every experimental test to date.
- Understanding the general theory of relativity requires familiarity with advanced mathematics.
Advanced Usage
- "within the framework of the general theory of relativity": used to specify that an explanation or prediction is based on this particular theory.
- The existence of black holes is predicted within the framework of the general theory of relativity.
- Often abbreviated in technical contexts as "general relativity" or the initialism "GR".
Variants and Related Words
- General Relativity (n): The common abbreviated form of the term.
- Special Theory of Relativity (n): Einstein's earlier theory, upon which general relativity expands, dealing with physics in the absence of gravitational fields.
- Relativity (n): The broader concept encompassing both the special and general theories.
Synonyms
- Einstein's Theory of Gravitation: A direct synonym emphasizing its description of gravity.
- Geometric Theory of Gravity: A descriptive synonym highlighting its core premise that gravity is geometry.
Related Phrases
- Principle of Equivalence: The foundational concept that gravitational and inertial mass are equivalent, a cornerstone of the theory.
- Curvature of Spacetime: The central geometric description of gravity in the theory.
- Field Equations: Refers to Einstein's field equations, the core mathematical formulas of the theory.
Noun
-
a generalization of special relativity to include gravity (based on the principle of equivalence)
