We show that in the case that gravity couples linearly to the field, some severe conditions on the field's potential have to be imposed. However, in non-linear case, it is quite generic to avoid the singularity with single scalar field.","authors_text":"Taotao Qiu","cross_cats":["astro-ph.CO","gr-qc","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2010-07-17T14:14:25Z","title":"Can the Big Bang Singularity be avoided by a single scalar field?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1007.2929","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":"sha256:8b6a0125ad7a446f865b2d9b510aa3cfc64ba59d7398475a60f0362241dbe2c6","target":"record","created_at":"2026-05-18T04:39:18Z","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":"99f00c83d7d360db7c7874651e0da457dcf734ff9f7d4f967ff6b5dabeaa0d05","cross_cats_sorted":["astro-ph.CO","gr-qc","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2010-07-17T14:14:25Z","title_canon_sha256":"ceec3d3245bada9d3f4c06191c137242b11d02f6f519985f97cfd6eac8d41cf9"},"schema_version":"1.0","source":{"id":"1007.2929","kind":"arxiv","version":2}},"canonical_sha256":"c3171406d34823adb7a9792e7580ea5ea30d966351cf344119cb39106be1aaa1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c3171406d34823adb7a9792e7580ea5ea30d966351cf344119cb39106be1aaa1","first_computed_at":"2026-05-18T04:39:18.126536Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:39:18.126536Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"z8uTegF0E8UWsieJrAKmKNSxADXGFIvQZ54b/wZFwKcDENdUYRQXTCelYtjIJBYFi3ZQZtjJziinEVCvwjPcAg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:39:18.127175Z","signed_message":"canonical_sha256_bytes"},"source_id":"1007.2929","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8b6a0125ad7a446f865b2d9b510aa3cfc64ba59d7398475a60f0362241dbe2c6","sha256:22d1e3633e2cfce6e7554d1ad74de8ae11777cd08c87cacc190dbe81f10b382b"],"state_sha256":"63ce8ddb67bd77d817869264dd6121e8472db5f7e3d6a3db2b93bcbf515ecc1f"}
