Meaning and Definition
Einstein's theory of gravitation, describing gravity not as a force but as the curvature of spacetime caused by mass and energy.
The branch of physics developed by Albert Einstein (1915), which supersedes Newton's law of universal gravitation. It provides a unified description of gravity as a geometric property of four-dimensional spacetime. Key predictions include gravitational time dilation, the bending of light by gravity, and the existence of black holes and gravitational waves.

Common Mistakes When Using “general relativity”
- Using 'general relativity' to refer to special relativity.
- Pronouncing 'relativity' with stress on the first syllable (/ˈrel.ə.tɪv.ə.ti/). Correct stress is on the third syllable.
- Treating it as a plural noun (e.g., 'general relativities are...'). It is a singular, uncountable noun phrase.
FAQ
Frequently Asked Questions
Special relativity (1905) deals with physics in the absence of gravity, particularly objects moving at constant speeds. General relativity (1915) is the theory of gravity, incorporating acceleration and describing gravity as spacetime curvature.
Yes, indirectly. The GPS satellite system must correct for both special and general relativistic time dilation effects to provide accurate positioning data on Earth.
It has been extensively confirmed by numerous experiments and observations (e.g., gravitational lensing, Mercury's orbit, gravitational waves, black hole imaging), making it one of the most successful scientific theories.
A clock ticks slower in a stronger gravitational field (like near Earth) compared to a weaker one (like in space). This 'gravitational time dilation' is a direct result of general relativity.
General relativity is usually scientific/formal in register.
General relativity: in British English it is pronounced /ˌdʒen.rəl ˌrel.əˈtɪv.ə.ti/, and in American English it is pronounced /ˌdʒen.ər.əl ˌrel.əˈtɪv.ə.t̬i/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Imagine a heavy ball (a planet) on a stretched rubber sheet (spacetime). The dent it creates is general relativity – gravity as curved space, not a pulling force.
Conceptual Metaphor
SPACETIME IS A FABRIC (that can be warped and curved). GRAVITY IS GEOMETRY/CURVATURE.
