The ACORN Cosmology Suite: ACORN solves Dark Matter, Dark Energy and Black Holes

This document presents a four-paper suite built on the ACORN framework (A CurvatureOrigin Reality Network): a finite 5-dimensional curvature model that replaces singularities, infinities, and quantum postulates with a single geometric principle. In ACORN, all physical phenomena arise from closed and open curvature modes of a compact fifth dimension, while the observable 4-dimensional universe is a projection of this finite geometric structure.The four papers collected here address: (1) the foundations of ACORN and the finitecurvature replacement of traditional field theory; (2) the emergence of dark matter as high closed curvature modes; (3) the geometric origin of dark energy as a spectral gradient in thefinite curvature spectrum; (4) the complete removal of black-hole singularities through a finite-curvature core and horizon projection geometry. Together, these works suggest that general relativity, electromagnetism, quantum structure, and the dark sector arise from one underlying mechanism: the finite curvature algebra of a compact 5-dimensional manifold. The complete technical development and proofs of the ACORN framework are available in Volume 2 (ACORN Foundations) and Volume 3 (ACORN: Proofs).
