The memory effect is understood at future null infinity as a transition induced by null radiation from a Poincar\\'e vacuum to another vacuum. Those are related by a supertranslation, which is a fundamental symmetry of asymptotically flat spacetimes. In this essay, I argue that finite supertranslation diffeomorphisms should be extended into the bulk spacetime consistently with canonical charge conservation. It then leads to fascinating geometrical features of gravitational Poinca","authors_text":"Geoffrey Comp\\`ere","cross_cats":["gr-qc"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2016-06-01T18:07:33Z","title":"Bulk supertranslation memories: a concept reshaping the vacua and black holes of general relativity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.00377","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:f2a793cffefe337597004781d8c6a8418fbe0ea7eadbc604233f3b5be6da4b12","target":"record","created_at":"2026-05-18T00:59:24Z","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":"cda15ade9049e447529249238159f157aef199445d48d9bd6ae0fd00e3aa473f","cross_cats_sorted":["gr-qc"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2016-06-01T18:07:33Z","title_canon_sha256":"793ffcb3da3d70e5d5572ecf93fbc2a7788a0046541f058c8b2715a6ad5336cb"},"schema_version":"1.0","source":{"id":"1606.00377","kind":"arxiv","version":1}},"canonical_sha256":"30cca3ad8db5878a7301d9f4b21d3843128b45f4bcfe2ab720279f223d0b87ec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"30cca3ad8db5878a7301d9f4b21d3843128b45f4bcfe2ab720279f223d0b87ec","first_computed_at":"2026-05-18T00:59:24.902342Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:59:24.902342Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wVsCiZJgPoOp+faulMmB/tlnxn03h1cgilOihmQxGg+MqnCI0+60PQq/aKd4Xli3c8QeJxyMCc7FQn9yQtLdDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:59:24.902996Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.00377","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f2a793cffefe337597004781d8c6a8418fbe0ea7eadbc604233f3b5be6da4b12","sha256:1180e57bb0301570c50ee65d55a46c56534b00e31fcbafcf8a2a38ed88847d99"],"state_sha256":"df8a1f5aa1fd024a560f8089b7b0df02c75be669c382504ac2c8f5e25e9513c4"}
