Gauge theory gravity (GTG) is a theory of gravitation cast in the mathematical language of geometric algebra. To those familiar with general relativity, it is highly reminiscent of the tetrad formalism although there are significant conceptual differences. Most notably, the background in GTG is flat, … See more The foundation of GTG comes from two principles. First, position-gauge invariance demands that arbitrary local displacements of fields not affect the physical content of the field equations. Second, rotation … See more • David Hestenes: Spacetime calculus for gravitation theory – an account of the mathematical formalism explicitly directed to GTG See more The field equations are derived by postulating the Einstein–Hilbert action governs the evolution of the gauge fields, i.e. See more For those more familiar with general relativity, it is possible to define a metric tensor from the position-gauge field in a manner similar to tetrads. In the tetrad formalism, a set of four vectors $${\displaystyle \{{e_{(a)}}^{\mu }\}}$$ are introduced. The … See more
