What a gravitational successor would still need

A gravitational wormhole claim would have to identify, in one model:

1. the metric or justified effective geometry and the regions called mouths and throat;

2. its gravitational equations and the matter or quantum stress assumptions appropriate to the claim;

3. the relevant causal structure and boundary conditions;

4. an injection, propagation, and extraction experiment supporting a signal-crossing claim;

5. the microscopic input, all inaccessible outputs, and a physical receiver or collection interface;

6. quantitative comparisons between those objects and any finite channel proxy.

An energy-condition statement must be supplied rather than inferred from entanglement. Different wormhole constructions have different physical assumptions; the finite certificate proves no universal gravitational energy-condition theorem MorrisThorne,GaoJafferisWall.

Em03-A's supplied calculation uses a prescribed Schwarzschild background and horizon. It does not generate a new horizon or wormhole from this schedule CheungEm03AF. The ER $=$ EPR proposal and gravitational teleportation accounts remain external comparisons MaldacenaSusskind,MaldacenaStanfordYang. They are not a geometric dictionary for the finite certificate.
