It is also a black hole whose event horizon spins with respect to infinity. An observer entering the hole necessarily ends up at a \"singularity\"; there are no inner horizons.\n  In the construction we take the quotient of 2+1 dimensional anti-de Sitter space by a discrete group Gamma. A key part of the analysis proceeds by studying the action of Gamma on the boundary of the spacetime.","authors_text":"(2) Fysikum, Ingemar Bengtsson (2), Soren Holst(2) ((1) Norra Reals gymnasium, Stefan Aminneborg (1), Stockholm, Stockholm University)","cross_cats":[],"headline":"","license":"","primary_cat":"gr-qc","submitted_at":"1998-05-08T18:10:34Z","title":"A Spinning Anti-de Sitter Wormhole"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"gr-qc/9805028","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":"sha256:6c01819de29a07d14f06ede1af4f4a9beddbef46495bbf71c127d40f84f85d03","target":"record","created_at":"2026-07-04T16:08:48Z","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":"0f28862eb71f0447a64da30f9f9a7bcea5163cb5b65d432f6a2dda12ad5c871f","cross_cats_sorted":[],"license":"","primary_cat":"gr-qc","submitted_at":"1998-05-08T18:10:34Z","title_canon_sha256":"c585b9e9385636983c84621b41600104344596e5e78816f5b7f24031479ad142"},"schema_version":"1.0","source":{"id":"gr-qc/9805028","kind":"arxiv","version":2}},"canonical_sha256":"4b363676efbf6894abf996b39905240743a78da6e5fd570dce041c6cac9b2077","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4b363676efbf6894abf996b39905240743a78da6e5fd570dce041c6cac9b2077","first_computed_at":"2026-07-04T16:08:48.602919Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:08:48.602919Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hQnHV5CJzxEWX+0ZvBc27w7xtefmXtG+CdSaBLVGGFz20a4lKJNTIzefRLeeG0FJDq8cZunXCT4x8PLLwE5IBw==","signature_status":"signed_v1","signed_at":"2026-07-04T16:08:48.603350Z","signed_message":"canonical_sha256_bytes"},"source_id":"gr-qc/9805028","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6c01819de29a07d14f06ede1af4f4a9beddbef46495bbf71c127d40f84f85d03","sha256:25981edf0dbc4be9b6400d2e95623b98781beab42165cf612900064ccfe359b8"],"state_sha256":"52fe6f4f9201b33b547e5ca530a687678787d83f219131d3d9549db9796b8faa"}
