Once this is imposed, gravity amplitudes are obtained using two copies of gauge-theory diagram numerators. Here we conjecture that this duality persists to all quantum loop orders and can thus be used to obtain multiloop gravity amplitudes easily from gauge-theory ones. As a nontrivial test, we show that the three-loop four-point amplitude of N = 4 super-Yang-Mills theory can be arranged into a form satisfying the duality, and by taking double copies of the diagram numerators we obtain the corresponding amplitude of N = 8 supergravity. We also remark on a non-supersymmetric two-loop test based on pure Yang-Mills theory resulting in gravity coupled to an anti-symmetric tensor and dilaton.","external_url":"https://arxiv.org/abs/1004.0476","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T05:55:24.507756+00:00","pith_arxiv_id":"1004.0476","created_at":"2026-05-10T22:10:47.374148+00:00","updated_at":"2026-05-25T05:55:24.507756+00:00","title_quality_ok":true,"display_title":"Perturbative Quantum Gravity as a Double Copy of Gauge Theory","render_title":"Perturbative Quantum Gravity as a Double Copy of Gauge Theory"},"hub":{"state":{"work_id":"fa884d2f-8720-484f-a4b9-803ad37cccbf","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":20,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2021-08-09T13:28:35+00:00","last_pith_cited_at":"2026-05-14T11:23:30+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":"2026-06-01T12:53:28.333884+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":7}],"polarity_counts":[{"context_polarity":"background","n":7}],"runs":{},"summary":{},"graph":{},"authors":[]}}
