First, we introduce the information loss problem; second, we provide a critical assessment by thoroughly inspecting the assumptions underlying its formulations. In particular, we argue that if we work in the regime of validity of semiclassical gravity and do not add additional assumptions that are not necessary for the Hawking calculation, the answer to the question in the title is NO. In other words, the black hole evaporation is certainly unitary as predicted by quantum field theory in curved spacetime. However, if additional assumptions are added, such as","authors_text":"Francesco Di Filippo, Luca Buoninfante","cross_cats":["hep-th"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2025-04-01T08:07:54Z","title":"Is the information loss problem a paradox?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.00516","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:ef1dc10b3f4208ce19db369f5befe1444f90540df5fe02666e197b8b477ed0df","target":"record","created_at":"2026-07-05T10:42:46Z","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":"215e06b17c7721d497b5862e9203f88120f704302087eb7db3503e45daa6b931","cross_cats_sorted":["hep-th"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2025-04-01T08:07:54Z","title_canon_sha256":"a6dc9ea2e138461003284e17ea6aefd4bec247d65fd5337ae045f7e134573696"},"schema_version":"1.0","source":{"id":"2504.00516","kind":"arxiv","version":1}},"canonical_sha256":"cf9681c09a481cf831b75e758871c2b89536be16c943aeb545a2a2198ffc32f9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cf9681c09a481cf831b75e758871c2b89536be16c943aeb545a2a2198ffc32f9","first_computed_at":"2026-07-05T10:42:46.367048Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:42:46.367048Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2Lhx4ET6KYG/rLkfZ1uIG7HnLPxMlIVBdHAIai3/+38y6TRWVnqx4fWPNKA1LNSUxQJp6cbedRagl6xrRIoOAA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:42:46.367524Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.00516","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ef1dc10b3f4208ce19db369f5befe1444f90540df5fe02666e197b8b477ed0df","sha256:39678e5a20c7a59abcce284ee98372db82b7c271ba2cbdb86a2bef973deee537"],"state_sha256":"a15e2eb8d12d7fb06c7496724bdab9fbfa8666f206d99904fcd0fab4f346f9a6"}
