P55: Clarifications and Scope of CCEGA — Warp Factor, Bulk Weyl Tensor, and Sgr A* Reclassification

We clarify four foundational aspects of CCEGA: (1) the correct warp factor is W = −k|y|exp(−ρ/ρ_c); (2) the bulk Weyl tensor is zero — the bulk is pure AdS₅; (3) no cosmological bounce is currently derivable from CCEGA; (4) Sgr A* is reclassified as a CCEGA black hole with horizon (M >> M_crit = 14.75 M☉), not a black star. The interior ρ_c surface of Sgr A* is at R = 971 km. This paper corrects implicit assumptions in earlier CCEGA papers and establishes the scope of the framework.

Abstract

We clarify four foundational aspects of CCEGA: (1) the correct warp factor is W = −k|y|exp(−ρ/ρ_c); (2) the bulk Weyl tensor is zero — the bulk is pure AdS₅; (3) no cosmological bounce is currently derivable from CCEGA; (4) Sgr A* is reclassified as a CCEGA black hole with horizon (M >> M_crit = 14.75 M☉), not a black star. The interior ρ_c surface of Sgr A* is at R = 971 km. This paper corrects implicit assumptions in earlier CCEGA papers and establishes the scope of the framework.
