Definition
C2General Relativity
(technical, academic)A mathematical function that describes the geometry and curvature of spacetime.
Example
- The spacetime metric is essential for calculating how objects move in the presence of gravitational fields.
C2Physics
(technical)A tensor that defines distances and angles between nearby points in spacetime, incorporating both spatial and temporal dimensions.
Example
- Physicists use the spacetime metric to determine the interval between two events in spacetime.
C2Astrophysics
(technical)A tool used to measure the geometry of the universe, particularly in curved spacetime.
Example
- In astrophysics, the spacetime metric helps in understanding the structure and expansion of the universe.
