Some surveys see less clumping than predicted, and the cosmological limit on neutrino mass now presses against the minimum allowed by laboratory experiments.","title":"Growth of structure and the neutrino mass","topic_ref":null,"why":"These measurements test gravity and dark matter on large scales and give the most sensitive route to the absolute neutrino mass scale."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"7f5d118cb8a64bd99639aa18f99daf7cb794d9366c6bec82eeea82eef99d0ccd","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"d52f0fa9ec4dfdd48e737ac07f704bebac9def50599672982b8443b4dac079e6","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"BY_GyzWMVngT1yeIle4dfuLBYnptPEfUDN9M60H0t6H3D-Xq5F-d9YstAej5ww5xYCd1_UUasN0Bmbh45QDfDA"},"schema":"pubphys.envelope/1"},"record_hash":"7f5d118cb8a64bd99639aa18f99daf7cb794d9366c6bec82eeea82eef99d0ccd","leaf_index":193}
