General relativity was a classical field theory formulated by Albert Einstein in 1915 that describes gravity as the curvature of four-dimensional spacetime in the presence of matter or energy using Riemannian geometry. (TNG: "The Nth Degree")
The five types of resonances of the subquantum states associated with transitional relativity are, in alphabetical order, asymmetrical, inverted, phased, stable and universal. (TNG: "The Mind's Eye")
This theory unified gravity with acceleration. This is shown through an example of an elevator in space, if accelerating upward, the person occupying the elevator feels as if he is in a gravitational field.
