PFUSRC-040 The Vertical-Horizontal Coordinate System of Celestial Topology Structure Evolution--Cross-Scale Empirical Evidence for the Bicone Skeleton from Asteroids to Stars

Previous studies in this series have demonstrated that the internal structures of the Sun (Paper 036), Earth (Paper 037), and the Moon (Paper 039) conform to the 45°triple coaxial bicone skeleton. To establish the full-scale universality of this topology, this paper further examines Ceres and Vesta in the asteroid belt (diameters ∼500-1000 km), as well as the ancient crust of Mars. This paper proposes a ”Celestial Topology Coordinate System” with the vertical axis representing celestial scale (logarithm of diameter) and the horizontal axis representing intrinsic activity (integrated metrics: internal temperature, presence of liquid layers, volcanic/tectonic activity intensity, magnetic field strength). Placing the Sun, Earth, Moon, Mars, Vesta, and Ceres into this coordinate system reveals that their ”skeleton visibility” (from direct surface exposure to deep burial requiring inversion) strictly follows a 45°isocline distribution--smaller, less active bodies exhibit more exposed skeletons; larger, more active bodies exhibit more deeply buried skeletons. Based on this coordinate system, this paper systematically organizes observational evidence for each body: isolated conical peaks and gravity asymmetry on Ceres; equatorial ridge and antipodal depression on Vesta; north-south hemispheric dichotomy and aligned volcanic chains on Mars; mascon rings and moonquake concentration on the Moon; plate boundaries and seismic belts on Earth; and sunspot belts and helioseismic structure on the Sun. All evidence is consistent with the predicted projections of the bicone skeleton. This paper further proposes testable quantitative predictions: Ceres conical peak slope =45°± 5°; angular spacing of isolated volcanoes on Ceres containing 12/11 harmonics; Vesta equatorial ridge height variation exhibiting 12/11 periodicity; spacing ratio of Martian Tharsis volcanoes =12/11; angle between Martian north-south dichotomy boundary and equator =45°± 5°; small asteroids (<200 km) should not possess complete bicone skeletons. These predictions can be tested using existing or future observational data. This paper completes the full-scale empirical validation of the PFUSRC system across scales from ∼500 km to ~1.4 ×10⁶ km and from frozen fossils to extremely active bodies, demonstrating that the 45°triple coaxial bicone is a universal geometric constraint in the process of matter aggregating from a discrete state into a structured state. Its manifestation varies only with celestial scale and intrinsic activity, while the underlying geometric rules remain invariant.
