This theoretical scenario should be tested via the state-of-the-art in gravitational experiments -- the current and upcoming gravity-wave detectors. Indeed, the existence of extra dimensions leads to oscillations that leave a spectroscopic signature in the gravity-wave signal from black holes. The detectors that have been designed to confirm Einstein's prediction of gravity waves, can in principle also provide tests and constraints on string theory.","authors_text":"Chris Clarkson, Portsmouth), Roy Maartens (ICG","cross_cats":["gr-qc","hep-th"],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2005-05-13T09:15:02Z","title":"Gravity-wave detectors as probes of extra dimensions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0505277","kind":"arxiv","version":1},"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":"sha256:4e0b2817d3aec06cef460eb321b2e88a00bbdbdf54d9f37be4f442f5a47cc22e","target":"record","created_at":"2026-05-18T02:40:25Z","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":"981915160a69b41fc0271108cb2a091b7a2bd3d16f030008a87ebc1483e9ce89","cross_cats_sorted":["gr-qc","hep-th"],"license":"","primary_cat":"astro-ph","submitted_at":"2005-05-13T09:15:02Z","title_canon_sha256":"6111622947fd7846226ee165504a601a3ac12a34f48cbf1491bce46ca8cf7a6a"},"schema_version":"1.0","source":{"id":"astro-ph/0505277","kind":"arxiv","version":1}},"canonical_sha256":"3454db72f7c98a108cde07297014fd759501b7ddb6fb91b98fb08fe5479bb2eb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3454db72f7c98a108cde07297014fd759501b7ddb6fb91b98fb08fe5479bb2eb","first_computed_at":"2026-05-18T02:40:25.639616Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:40:25.639616Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bETibuZwIxfPbwF8DxhOHBJkRWeX42zztZHmoKkUWAQQI3o9Gra/NfDjcSVZ5onebzIlXIyHL6qNs9vsx4mMAA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:40:25.640045Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0505277","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4e0b2817d3aec06cef460eb321b2e88a00bbdbdf54d9f37be4f442f5a47cc22e","sha256:dddf187aae8c46db636044b7b9368e106758c93a8870c9ef68294126ae6712dc"],"state_sha256":"3af07fc4ba8d977a27f67a84085952a86570be241dbe0087f97315bb6dcc9250"}
