Preprint: Low-multipole CMB suppression (Δχ^2 ≈ 39.1) via 1+1D boundary condition

This repository hosts the preprint and numerical simulation data for the Damascus Topology Model (DTM), a geometric framework addressing the anomalous suppression of large-scale power ( 5) in the cosmic microwave background (CMB). Operating as an alternative to standard inflationary modifications, the DTM proposes that the macroscopic universe occupies a negatively curved, toroidal dodecahedral manifold. To regulate the expansion and prevent geometric tearing at the initial singularity (t=0), the transition from the parent aeon is governed by a 1+1D fractal conformal boundary acting as a topological throttle. This restrictive lower-dimensional boundary condition acts as a high-pass filter, heavily dampening the largest spatial resonances (k-modes) while leaving smaller-scale macroscopic structures entirely undisturbed. Through numerical Sachs-Wolfe integration calibrated at kᵥₐₗᵥₑ = 0.00028 Mpc⁻¹ and a compaction density of β = 3.5, the model extracts a theoretical 62% suppression of the quadrupole (=2) and a 38% suppression of the octupole (=3). Evaluated against Planck 2018 temperature (TT) data, the DTM yields a total χ^2 ≈ 6.1 (reduced χ^2 ≈ 0.22) compared to the standard baseline of χ^2 ≈ 45.2, demonstrating a robust statistical improvement of Δχ^2 ≈ 39.1 and completely resolving the low-multipole tensio n.
