Flowing ultracold gases (Bose-Einstein condensates) and other fluids with sonic horizons, places where the flow outruns sound, let experiments test whether this glow survives changes at short distances.","title":"Trans-Planckian origin and laboratory analogs of Hawking radiation","topic_ref":null,"why":"Laboratory analogs are the only experimental access to Hawking's prediction, and the trans-Planckian question decides whether that prediction depends on unknown Planck-scale physics."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"4f72aa7f49ff2207b153ba914ff04aca2adf093119262ec376588bbea7b4ba32","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"fdec5f666f099833bb3c421b0514405a3b006567c553c45d13fd2aacd56d19a0","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"r4egzgxkXNloYyjpXqbJ1_gYf-5ZrQr5VxIFIPEYywATHdsl2ILSrZeqNR9-1O59Dcu9_okJ5fxfoCO88CpsBA"},"schema":"pubphys.envelope/1"},"record_hash":"4f72aa7f49ff2207b153ba914ff04aca2adf093119262ec376588bbea7b4ba32","leaf_index":225}
