With enough bulk entanglement, the bulk Hilbert space of a closed universe can be holographically encoded in the CFT. We clarify the relation of this encoding to observer-clone proposals and refute recent arguments about the breakdown of semiclassical physics in such spaces. In the limit of no bulk entanglement, the holographic encoding breaks down. The oft-cited one-dimensional nature of the closed universe Hilbert space represents the limitation of the external (CFT) Hilbert ","authors_text":"Alejandro Vilar L\\'opez, Brian Swingle, Martin Sasieta, Pratik Rath, Stefano Antonini","cross_cats":["gr-qc","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2025-07-14T18:00:00Z","title":"The Baby Universe is Fine and the CFT Knows It: On Holography for Closed Universes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.10649","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6b1a865733729fe6f7ddcbcc22757e3635b158ab0732a8840d1a28e2e4330e3f","target":"record","created_at":"2026-07-05T11:50:38Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"5d2721617935516a1114b6c69d6ef73ce5bd20cb9011a5795474c608ee76914e","cross_cats_sorted":["gr-qc","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2025-07-14T18:00:00Z","title_canon_sha256":"b90068a20a76c97b4378370fb2553224917201b7f6cc80938afa98a99ab09acf"},"schema_version":"1.0","source":{"id":"2507.10649","kind":"arxiv","version":2}},"canonical_sha256":"5a87017ff4477cc9b25b28f0c9166eedbe0eb559e29858271805e2765ec3705b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5a87017ff4477cc9b25b28f0c9166eedbe0eb559e29858271805e2765ec3705b","first_computed_at":"2026-07-05T11:50:38.409369Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:50:38.409369Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"f7v/05Fbs3MRdy7r91R85yAji/3l4jkON9JJYfvMzlqFoGBUCtbJLYFvfplqJonj9XKcG6M5DVOElWIGk56NDw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:50:38.409801Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.10649","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6b1a865733729fe6f7ddcbcc22757e3635b158ab0732a8840d1a28e2e4330e3f","sha256:e3da0d68b001478ee51cbd94c5d0f1ebf109b0ce69b5adfd4234f915459922f9"],"state_sha256":"6dccddbb524f7b33e65bad00c11d024f015d46767c6931d85e65e8265f8a7120"}
