We address this question by constructing an algebra of gravitationally-dressed observables accessible to a comoving observer in FLRW spacetimes that are asymptotically de Sitter in the past, describing an inflationary epoch. An essential quantized degree of freedom is the zero-mode of the inflaton, which leads to fluctuations in the effective cosmological constant during inflation and prevents the existence of a maximum entropy state in the semiclassical limit. Due to the inaccessibility of measurements beyond our cosmological horizon, we de","authors_text":"Gautam Satishchandran, Jonah Kudler-Flam, Samuel Leutheusser","cross_cats":["gr-qc","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2024-06-03T18:00:00Z","title":"Algebraic Observational Cosmology"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2406.01669","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":"sha256:0f7ab58461f62a4f66b282e9d97d2892921afcce5a892b51874432aa10114d69","target":"record","created_at":"2026-07-05T08:37:53Z","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":"2f071c2a14fc0ba0fd0e90fd911be46408337ba77ba02e4f48419681bf961814","cross_cats_sorted":["gr-qc","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2024-06-03T18:00:00Z","title_canon_sha256":"a5e9e326a843dd1ea1113afc92ee57f9d66bb8ec2efe5dc3d9c46ddd52d63ecb"},"schema_version":"1.0","source":{"id":"2406.01669","kind":"arxiv","version":2}},"canonical_sha256":"dfd0fefc85edffc81789ef3ca25edf3c828bb1b3205824866b904fea434a1678","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dfd0fefc85edffc81789ef3ca25edf3c828bb1b3205824866b904fea434a1678","first_computed_at":"2026-07-05T08:37:53.350377Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:37:53.350377Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ug+3h9NxYH9cHbvXz2O1hBTlzLqc4dywDNyq5y5Cl1WeKy5Nv1I0v/nM95tgQy6zembwygvun7+2v9eFZCrWAg==","signature_status":"signed_v1","signed_at":"2026-07-05T08:37:53.350833Z","signed_message":"canonical_sha256_bytes"},"source_id":"2406.01669","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0f7ab58461f62a4f66b282e9d97d2892921afcce5a892b51874432aa10114d69","sha256:14bf51e1aea107154a9bd3c7ab52239b8bb5d24c5ccba16b456afce00e0cd7b7"],"state_sha256":"28824aeca4f6c2681b08bd8d35ea11ce360ff8af1ee5a29ac36798caaf8d6e84"}
