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:

  • Calls the case “cuentos” (tales) and “charlatanería” (charlatanism); explicitly frames it as a publicity stunt (“montaje con fines publicitarios”).
  • Notes that neither the university-of-georgia nor any Mexican university has published an official C-14 report for the sphere.
  • Argues that science requires peer-reviewed publication, not viral social-media circulation.

“What exists about the sphere so far are tales, charlatanism. There is nothing with scientific backing… If it had any substance, the news would circulate in scientific media, specialized journals, not on TikTok.” — Marino Guarín (translated)
