Position on the Buga Sphere
Per src-buga-sphere-el-pais-cali-maussan-handoff-2025-10 and src-buga-sphere-infobae-true-origin-2025-10:
- The sphere’s components — including identified optical fibers in its structure — are “very terrestrial.”
- No scientific studies support jaime-maussan’s claims.
- The object is most plausibly a contemporary terrestrial artifact or publicity stunt, comparable to the Arizona desert monolith.
“There is no technology in the famous Buga Sphere that is ‘from another world.’ On the contrary, its compounds are very terrestrial, like the optical fibers that have been identified.” — Santiago Vargas (translated)
