This short review faces this challenge under a novel perspective. Instead of separating quantum-gravity effects of a specific model between UV and IR regimes, we consider a general feature, possibly common to many frameworks, where all scales are affected and spacetime geometry is characterized by a complex critical exponent. This leaves a log-oscillating modulation pattern in the cosmic microwave background spectrum and gives a unique opportunity, illustrated with the exa","authors_text":"Gianluca Calcagni","cross_cats":["hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2017-09-22T17:02:24Z","title":"Detecting quantum gravity in the sky"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.07845","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":"sha256:1f09aff3389cf1b68560709dcacbbaf387a9c44e32d4d2e254fe6bd16ae5edd1","target":"record","created_at":"2026-05-18T00:32:20Z","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":"a67958b82cfacc98cf011a4c2100be1abb33457b1b2b15a4fe669613eaf77fde","cross_cats_sorted":["hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2017-09-22T17:02:24Z","title_canon_sha256":"0fa01d51bad05e03c013b7b0904c1af4812fb7b19aff8b8c310b0c5ecb8063e9"},"schema_version":"1.0","source":{"id":"1709.07845","kind":"arxiv","version":2}},"canonical_sha256":"31ee85989e359c0f92932cdf269614bef625a435f122b46a099cc662a3f1c1bf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"31ee85989e359c0f92932cdf269614bef625a435f122b46a099cc662a3f1c1bf","first_computed_at":"2026-05-18T00:32:20.114875Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:32:20.114875Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IS+FhlvvBC6nyzsRx91BMFFyrMyTy9mCK3Sx5n65mF0R+8dCyHUI8oHtOm1ChzKIQ/Y6oz4Fdr7YcNumvcUYDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:32:20.115565Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.07845","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1f09aff3389cf1b68560709dcacbbaf387a9c44e32d4d2e254fe6bd16ae5edd1","sha256:f7d92c7afd2ac6fddc7de8c189378550bed1a1d24c5bea12741a74c211643e0f"],"state_sha256":"86ee9dd2c785fe43f9f1da3f7e8031c1f778eecf3cc987e3524934b981ebc829"}
