Operational Freeze-Out of Causal Propagation in an Effective Black-Hole Core: A Toy Model Beyond Classical Geometric Validity
Yoshikuni Tsuno / 4 May 2026
This paper proposes a toy model for operational freeze-out of causal propagation in an effective black-hole core. It treats the vacuum constant as fixed while allowing an effective causal speed to become sector- and state-dependent.
Research Summary
- Defines an effective causal speed in a near-core black-hole model.
- Shows that when the ratio A/B vanishes sufficiently fast, core-to-shell communication time diverges.
- Frames “stopped light” as an operational freeze-out rather than a literal variation of the vacuum light constant.
