General Relativity in Six Dimensions: A Three-Temporal Extension of Spacetime Geometry

This paper introduces a six-dimensional extension of Einstein’s General Relativity by postulating three temporal and three spatial dimensions within a unified metric manifold. In this framework, spacetime becomes a dual 3S + 3T continuum, where the temporal dimensions form an orthogonal triad analogous to the spatial axes. The proposed model preserves Lorentzian covariance under the generalized metric signature (−,−,−,+,+,+), defining a multi-temporal geometry in which the familiar 3+1 spacetime arises as a projection from higher-order temporal structure.
