I will discuss the criteria for a successful early universe cosmology, compare a couple of the proposed scenarios (inflation, bouncing cosmologies, and the {\\it emergent} scenario), focusing on how future observational data will be able to distinguish between them. I will argue that we need to go beyond effective field theory in order to understand the early universe, and that principles of superstring theory will yield a nonsingular cosmology.","authors_text":"Robert Brandenberger (McGill University)","cross_cats":["astro-ph.CO","gr-qc","hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2019-11-14T12:20:25Z","title":"Fundamental Physics, the Swampland of Effective Field Theory and Early Universe Cosmology"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1911.06058","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:af31a10954548b635ea31d0606e6f5cb0f883e65b8c334f9fa91859296be3282","target":"record","created_at":"2026-07-05T00:19:14Z","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":"511442ad187d04f2f7d4e0de59478781fe37ee2211c67e9886fd72106ca7a05c","cross_cats_sorted":["astro-ph.CO","gr-qc","hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2019-11-14T12:20:25Z","title_canon_sha256":"699386344895ee6e9c64cf028a96e442ef90e6107ce36656221b1282cdf84da7"},"schema_version":"1.0","source":{"id":"1911.06058","kind":"arxiv","version":1}},"canonical_sha256":"0345bfac4bc4f389bc223cb0b2a2807981ecd44b7d8959a7bbd841f72b4a9be5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0345bfac4bc4f389bc223cb0b2a2807981ecd44b7d8959a7bbd841f72b4a9be5","first_computed_at":"2026-07-05T00:19:14.978498Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:19:14.978498Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"e7VyDlL9CCR92Kf/ZYQqFSOqRnnc/L/woJO0d0pcYMlQyBYna8CfWa2PtQKknolu39KwCKXeXNGNsokVBKDaCA==","signature_status":"signed_v1","signed_at":"2026-07-05T00:19:14.978897Z","signed_message":"canonical_sha256_bytes"},"source_id":"1911.06058","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:af31a10954548b635ea31d0606e6f5cb0f883e65b8c334f9fa91859296be3282","sha256:dae0cd16781217796a6270025ec73bc421b52dec2b52f7b82e475a53fab47e14"],"state_sha256":"697d435a7a40434903dfe052673f10a4c9bba63bd954fe4c0395c824da0c6782"}
