alternatives to general relativity Whitehead's theory Brans–Dicke theory teleparallelism f(R) gravity Einstein–Cartan theory relativity theory field equation gravity
There are alternatives to general relativity built upon the same premises, which include additional rules and/or constraints, leading to different field equations. Examples are Whitehead's theory, Brans–Dicke theory, teleparallelism, f(R) gravity and Einstein–Cartan theory.
