Definition

Mass is not in spacetime names the strong Kastner–Schlatter conjecture that the source of gravitational mass belongs to the quantum substratum from which spacetime emerges. The books mark this as internal to a speculative transactional-gravity program. They distinguish that ontological priority claim from measured curvature and explicitly reject an argument that ordinary general relativity makes curvature vanish wherever mass is located.

Explanation

The proposed ontology treats empirical spacetime as the record generated through quantum transactions. On its stronger reading, the source of the gravitational field is described by quantum states not contained within a classical 3+1 manifold. This is a programmatic metaphysical interpretation of matter and geometry, not a direct observation that gravitating bodies are absent from ordinary spatial experience.

RB1 corrects an attempted inference from vanishing curvature at matter. Ricci curvature and Weyl curvature do different work, and a Ricci-flat vacuum need not be flat spacetime. The corrected entry therefore does not turn the speculative claim into a theorem of Einstein’s equations or use a rubber-sheet analogy as a substitute for the geometry.

Both research volumes qualify the strong program. RB1 says nothing later depends on it; RB2 describes the mass claim as internal to Schlatter and Kastner’s theorizing rather than settled physics. AB likewise keeps substratum mass a frontier proposal. These restrictions are constitutive of the entry, not invitations to certify the conjecture by philosophical resonance alone.
