Einstein's Field Equations
(Redirected from Einstein Field Equations)
An Einstein's Field Equations is a tensor physics equation that relates the geometry of spacetime to the energy and momentum within it.
- AKA: Einstein Field Equations, EFE, General Relativity Field Equations, Gravitational Field Equations.
- Context:
- It can typically relate Spacetime Curvature to energy-momentum tensors.
- It can typically describe Gravitational Fields through metric tensors.
- It can typically predict Spacetime Geometry from matter distributions.
- It can often require Tensor Mathematics for mathematical manipulations.
- It can often admit Exact Solutions for symmetric configurations.
- It can often necessitate Numerical Relativity for complex systems.
- It can range from being a Vacuum Einstein's Field Equations to being a Matter-Filled Einstein's Field Equations, depending on its source terms.
- It can range from being a Linear Einstein's Field Equations to being a Nonlinear Einstein's Field Equations, depending on its approximation level.
- It can range from being a Static Einstein's Field Equations to being a Dynamic Einstein's Field Equations, depending on its time evolution.
- It can range from being a Cosmological Einstein's Field Equations to being a Local Einstein's Field Equations, depending on its cosmological constant.
