Supplement to Metallic Specimen

CLEARED For Open Publication Jul 01, 2024 Department of Defense OFFICE OF PREPUBLICATION AND SECURITY REVIEW All-domain Anomaly Resolution Office Supplement to Oak Ridge National Laboratory's Analysis of a Metallic Specimen July 2024

Overview

In 2022, The All-domain Anomaly Resolution Office (AARO) contracted with Oak Ridge National Laboratory (ORNL) to conduct materials testing on a magnesium (Mg) alloy specimen. This specimen has been publicly alleged to be a component recovered from a crashed extraterrestrial vehicle in 1947, and purportedly exhibits extraordinary properties, such as functioning as a terahertz waveguide to generate antigravity capabilities. In April 2024, ORNL produced a summary of findings documenting the laboratory's methodology to assess this specimen's elemental and structural characteristics, available on AARO's website.

ORNL assessed this specimen to be terrestrial in origin and that it does not meet the theoretical requirements to function as a terahertz (THz) waveguide. AARO concurs with ORNL’s assessment and provides this supplementary material to add historical context to account for its likely origin. The specimen’s characteristics are consistent with Mg alloy research and development projects and experimental manufacturing methods in the mid-20th century.

ORNL Materials Testing

AARO contracted with ORNL to conduct materials measurements to determine: - Whether this specimen is of terrestrial origin. - Whether this specimen could serve as a THz waveguide.

ORNL measured the isotopic ratios of Mg and lead (Pb) in the specimen and compared the values against mass standards. A material’s isotopic composition can provide valuable information about its origin and history. The specimen’s Mg isotopic composition falls within the expected values for a…
