Buga Sphere

The Buga Sphere is a basketball-sized metallic object that, per the recoverers’ account, fell to the ground in the Alto Bonito sector of Buga, Valle del Cauca, Colombia in March 2025. It was promoted publicly through 2025–2026 by Mexican ufologist jaime-maussan and co-presented with steven-greer at the May 8 2026 the-disclosure-project National Press Club event (src-greer-disclosure-event-npc-2026-05) as a possible non-human artifact. All physical, biological, and dating claims about the sphere are unverified, single-source, and disputed by named Colombian and international scientists.

Provenance (per recoverers)

Claims attributed to the sphere (all unverified)

  • Mass: initially estimated 2 kg, allegedly grew to ~10 kg over days.
  • Physical effects on handlers: vomiting, dizziness, metallic taste; lymphocyte DNA damage in handlers (cited in src-buga-sphere-ibtimes-ball-from-nowhere-2026-03).
  • Surface: seamless metallic appearance, “hard aluminum” construction, no atmospheric-entry pitting; 31 equatorial black dots; engravings described in pro-Maussan press as “proto-Sanskrit” or Paleo-Hebrew-like.
  • Internal structure: concentric layers; 31 microscopic resin-anchored channels likened to fiber-optic assemblies; 18 symmetric microspheres allegedly containing ~12,000-year-half-life radioactive isotopes; “self-healing micropores.”
  • Other: alleged gravity-offsetting EM field; 0.1% daily mass gain — all unsubstantiated.
  • Carbon-14 result of ~12,560 years for an internal resin sample, attributed to the University of Georgia but with no published lab report, named researchers, calibration data, or peer review (see src-buga-sphere-uga-carbon-date-claim-2025-10 for the promotional articulation; src-buga-sphere-carbon-dating-debunk-2026-04 and src-buga-sphere-ibtimes-ball-from-nowhere-2026-03 for the methodological rebuttals).

Scientific assessment

Colombian astronomers (src-buga-sphere-el-pais-cali-maussan-handoff-2025-10, src-buga-sphere-infobae-true-origin-2025-10) uniformly assess the object as a contemporary terrestrial artifact:

  • santiago-vargas (Universidad Nacional, Observatorio Astronómico): compounds are “very terrestrial”; identifies optical fibers in the structure; likens to the Arizona desert monolith publicity stunt.
  • marino-guarin (Escuela de Astronomía de Cali): “charlatanism”; “if it had substance, it would circulate in scientific journals, not on TikTok”; no UGA or Mexican-university report exists.
  • oscar-amaya-montoya (Fundación Casa de la Ciencia de Buga): “probable that this is a recent technological artifact manufactured on Earth”; AI-era video fabrication is plausible.
  • lauren-flor-torres (Universidad de Antioquia astrophysicist): the sphere’s pristine surface is inconsistent with atmospheric entry; real meteorites carry heat-fractured crusts.

International skeptics:

  • julia-mossbridge (University of San Diego, UAP researcher): the object “seems kind of like an art project… only humans can do”; urges submission to galileo-project-grade analysis.
  • Astrophyzix (src-buga-sphere-carbon-dating-debunk-2026-04): radiocarbon ages organic samples only, not inorganic containers; conflating resin age with object age is “a fundamental methodological error”; no UGA documentation exists.

Competing terrestrial provenance: an unnamed Bogotá laboratory reportedly told Vélez the sphere was part of an experiment they had been running since 2011 and asked for its return; Vélez refused.

Pattern

The Buga Sphere fits the jaime-maussan artifact arc — viral reveal, no documented chain of custody, “experts” without institutional affiliation, no peer review. The Colombian press (src-buga-sphere-el-pais-cali-maussan-handoff-2025-10) explicitly compares it to Maussan’s previously debunked Nazca “non-human” mummies (assessed in 2023 as composites of human/animal bone, glue, synthetic rubber, and plant fibers). See steven-greer for the parallel the-disclosure-project history with the Atacama humanoid.

A second Colombian sphere — the Valdías Mountain Range Sphere — was added to the Maussan narrative in May 2026 (src-buga-sphere-maussan-tv-valdias-report-2026-05).
