UFO (UFO)

UFO (UFO)

Abbreviated form of Unidentified Flying Objects, that is, unidentified flying objects. It is the Anglo-Saxon definition given to those phenomena, apparently inexplicable, that have to do with the appearance of objects both in the day and night sky.

Sightings of UFOs are repeatedly pointed out both by city or country people, and by observers specialized in the so-called "surveillance" of the sky. However, it has been shown that most of these occurrences are due to a misinterpretation of well-known phenomena.

Thus, for example, they are confused with UFOs artificial satellites in Earth orbit that reflect the rays of the Sun towards Earth, probe balloons that fly in the high atmosphere, electrical phenomena of the troposphere, phenomena such as auroras, meteors, meteorites, and racing cars , fast past jets and their trails, natural gas emissions from the ground or from the deep sea, etc.

A large number of alleged UFOs are also due to collective or individual suggestions that are manifested in certain periods of political and social tension, which are sometimes stimulated by science fiction literature. For all these reasons, many scientists believe that, in view of a thorough analysis, all UFO observations can be redirected to a known phenomenology; others, on the other hand, seem to remain unexplained and unexplained cases.

The popular belief is that UFOs are the manifestation of extra-terrestrial creatures that observe us from above, and that from time to time they visit us. However, until now, there is no official scientific evidence or evidence of contact with evolved creatures from other worlds.
