Radiocarbon Dating
Radiocarbon (carbon-14) dating measures C-14 decay in organic material to estimate the time since the organism stopped exchanging carbon with the atmosphere. Accelerator Mass Spectrometry (AMS) is the high-sensitivity modern variant, capable of dating sub-milligram samples up to ~50,000 years old.
Scope and limits
- Only ages organic material (plant matter, bone, resin, charcoal, shell).
- Cannot directly date inorganic objects (metals, ceramics, manufactured composites) unless intrinsic organics are demonstrably contemporaneous with the object’s formation.
- Dating organic contents of an inorganic container does not date the container — the contents may post-date, pre-date, or have been introduced after recovery.
- Contamination by modern carbon (handling, conservation resins, environmental exposure) can inflate apparent youth; contamination by older carbon (limestone, “old wood”) can inflate apparent age.
Validation requirements
A scientifically usable C-14 result requires:
- Published laboratory report.
- Named lab and named personnel / PI.
- Calibration data and stated error margins.
- Documented sample-prep methodology and a clean chain-of-custody.
- Ideally: independent replication and peer-reviewed publication.
Relevance to UAP / recovered-artifact claims
C-14 dating is used as a recurring rhetorical move in recovered-artifact presentations to imply non-terrestrial antiquity. The buga-sphere case is a current example: a claimed ~12,560-year date is attributed to the university-of-georgia for organic resin inside the sphere (src-buga-sphere-uga-carbon-date-claim-2025-10), but per src-buga-sphere-carbon-dating-debunk-2026-04 no UGA documentation exists, and even if accurate the resin date does not date the inorganic sphere. Colombian astronomer marino-guarin notes that no “official report” has been published by any university for the sphere.
