UFOLOGY Glossary Series - H
A series to help people new to the topic understand the terms, concepts, and language used in the study of UFOs and alien phenomena.
The world of ufology is vast, mysterious, and often overwhelming for newcomers and seasoned researchers alike. With decades of reports, theories, terminology, and classifications, understanding the language of UFO research is essential for making sense of the phenomena.
This Ufology Glossary is designed to be a living, evolving reference guide for anyone interested in the study of unidentified flying objects, alien encounters, and the deeper mysteries of our universe. Whether you're exploring government disclosures, diving into abduction accounts, or just trying to decipher terms like “CE-5” or “anti-gravity propulsion,” this glossary is your companion through the strange and fascinating world of UFO phenomena.
Each entry is organized alphabetically and includes clear, concise definitions to help demystify the language used by researchers, experiencers, and theorists across the field.
We begin with the letter A, and from there, the glossary will continue to grow—entry by entry, mystery by mystery.
Hybrid (Alien-Human Hybrid)
A being believed to be the result of genetic blending between humans and extraterrestrials, often reported in abduction accounts and linked to alien breeding programs.
