'Art's Parts' Bi/Mg metamaterial samples.

disputedphysical_evidenceModern Disclosure Nexus

Layered bismuth-magnesium fragments mailed to Art Bell (1996) claiming Roswell origin; tested by Puthoff/EarthTech; later ADAM samples.

Palm-sized micron-layered bismuth/magnesium(-zinc) fragments anonymously mailed to Coast-to-Coast host Art Bell in 1996 with a chain-of-custody letter claiming 1947 Roswell recovery. Held by Linda Moulton Howe, tested twice by Puthoff/EarthTech (including 2012, 'no anomalous outcome'), then sold into TTSA's ADAM project for $35k in 2019. The objects physically exist and were analyzed (documented); the extraterrestrial origin and 'engineered beyond terrestrial capability' claims are disputed — critics identify ordinary Bi-Mg alloy/slag. **Replication status:** mundane-explained · discredited-as-ET — Flagship TTSA/ADAM 'metamaterial'; the only govt-lab-grade analysis (ORNL 2024) is fully terrestrial.
