EL PROBLEMA DEL 'NO-CONTACTO' EXTRATERRESTRE: HIPÓTESIS SOBRE LA PROCEDENCIA DE LOS O.V.N.I.S.

This document is a detailed synopsis and introduction for a book titled 'The Problem of Extraterrestrial No-Contact' by Ignacio Darnaude Rojas-Marcos, dated July-August 1980. The author presents a comprehensive overview of the UFO phenomenon, framing it as a critical issue that has remained unresolved since the modern era of sightings began in 1947. Darnaude argues that the sheer volume of reports—estimated at millions of sightings—demands a serious, scientific, and philosophical inquiry into why these entities do not make formal contact with humanity. The text rejects superficial explanations and 'Chinese tales' (cuentos chinos), advocating instead for a rigorous, multi-disciplinary approach that draws on a vast library of ufological literature. The author categorizes the myriad of hypotheses into two main groups: 'Orthodox' explanations, which include misidentified celestial bodies (planets, meteors, stars), atmospheric phenomena (noctilucent clouds, electrical discharges, reflections), and conventional aircraft; and 'Heterodox' explanations, which range from secret terrestrial experimental craft to extraterrestrial hypotheses, psychic phenomena, and complex transdimensional or 'paraphysical' models. The document highlights the author's intent to provide a 'trench' perspective, utilizing over 450 cited authors and a deep bibliography to challenge official scientific establishments and provide a more nuanced understanding of the 'No-Contact' dilemma. The author posits that the UFO phenomenon is not a single problem but a complex, interconnected set of issues that may involve multiple types of entities or origins. The document concludes by emphasizing the need for a new 'Ufology' that reconstructs its foundations on solid, verifiable evidence rather than speculative myths, aiming to address the growing public anxiety regarding the 'invasion' of extraterrestrials.
