We provide calculations for the results quoted in that paper, explain how it fits into a broader (tensor) network of ideas, and elaborate on the hypothesis that black holes are the fastest computers in nature.","external_url":"https://arxiv.org/abs/1512.04993","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-04T06:49:38.450064+00:00","pith_arxiv_id":"1512.04993","created_at":"2026-05-10T07:21:55.134012+00:00","updated_at":"2026-07-04T06:49:38.450064+00:00","title_quality_ok":false,"display_title":"Complexity, action, and black holes","render_title":"Complexity, action, and black holes"},"hub":{"state":{"work_id":"1650e9f8-5a5d-4167-839e-2e3fbb88da3b","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":16,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2019-07-25T07:42:17+00:00","last_pith_cited_at":"2026-06-19T03:59:53+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-22T04:19:54.497374+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":8}],"polarity_counts":[{"context_polarity":"background","n":6},{"context_polarity":"support","n":1},{"context_polarity":"unclear","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
