Aether Tomography: Residual Cosmic Birefringence as a Probe of Organized Five-Dimensional Chronogeometric Structure This paper is Paper 2 in the Temporal Torque Memory and Aether Organization series. It develops Aether tomography as an observational framework for interpreting residual cosmic birefringence maps as projections of organized five-dimensional chronogeometric structure. Paper 1 established the five-dimensional chronogeometric coordinate system, \ (x, y, z, ᵥ, ₜ), \ and proposed that cosmic birefringence contains a universal topological component, \₀ = 116². \ The present paper extends that framework by treating the residual birefringence field, \ (, ), \ as an observable projection of hidden temporal-torque organization within the Aether. The total birefringence field is written as \ (, ) = ₀ + (, ). \ Aether tomography is defined as the inverse problem, \ (, ) ₜ (x), \ where ₜ (x) denotes temporal-torque density. The paper develops forward modeling, inverse reconstruction, harmonic decomposition, candidate QMU-native definitions of ₜ, simulated residual sky-map structures, and observational tests using Planck, ACT DR6, LiteBIRD, and future polarization surveys. A phenomenological forward model is introduced, \ (, ) = ₋₎ₒ ₜ (x), ds, \ where () is treated as an observational coupling coefficient whose QMU-native origin is reserved for future derivation. The paper also introduces harmonic observables, \ (, ) =, ₌ a ₌ Y ₌ (, ), \ and a handedness statistic, = ₘ m |a ₌|², \ as falsifiable tests for chronotorsional asymmetry. This work establishes residual cosmic birefringence not merely as a signal to be detected, but as a potential tomographic map of organized Aether domains.
