Are UFOs nuts-and-bolts spacecraft flown by extraterrestrials who traveled a long way (very long) across space to observe us? Repeatedly? For millennia? Er, maybe. But probably not. (For more on that, see BB contributor and heretical UFO researcher Jacques Vallée's 1990 paper "Five Arguments Against the Extraterrestrial Origin of Unidentified Flying Objects," available as a PDF here.) Fortean Times does a quick survey of more than two dozen other theories of the origin of UFOs, some quite far out and others that even a die-hard skeptic could love. Here are a few:
AWAKENINGS
At a point close to sleep, visual and auditory hallucinations are common, according to psychological studies. False awakenings, where a dream that includes a UFO encounter is misperceived as a waking memory, are also known. Some cases involving alien contact and bright lights seen outside bedroom windows have been successfully proven to fit these vivid experiences to which everybody is prone.IFOs
After investigation, analysts agree that between 90 and 95 per cent of all UFO sightings prove to be Identified Flying Objects. Over 300 different things have been misperceived as UFOs – including a bin bag, a shaggy dog and a telegraph pole. The Null Hypotheses proposes that all of the remaining unsolved cases would become IFOs given enough study and sufficient evidence. However, statistical analysis (like that conducted by the Battelle Institute and French aerospace researchers GEPAN) has indicated differences between solved and unsolved cases that challenge this proposal.KOOKS
After eliminating other options, a die-hard sceptic might offer the premise that 'kooks' see UFOs because of an innate desire to promote the mystical within their lives. They do so by introducing magic to mundane events so as to elevate their status amongst peers. No significant evidence has been published that more than a few witnesses are so motivated and most psychological profiles of UFO witnesses suggest they are stable individuals who sincerely believe that they have seen something odd.LENTICULAR CLOUDS
Unusual cloud formations have been proven to create some UFO sightings. Lenticular clouds with their disc or cigar structure can be especially impressive, and though rare in Britain they can form anywhere – one encounter occurred in Rochdale. Rarer cloud types such as noctilucent (which reflect the sun from below the horizon when the local area is in darkness) have also provided plenty of reports.MULTIVERSE
Physicists have attempted to explain some of the latest problems of cosmology by developing a theory of multiple interlocking universes. This proposes a series of universes that can be linked via subspace but where our limited perception restricts awareness of all but our own. Some universes could be closely aligned to ours and others would have evolved very differently. Rather than aliens coming to Earth from another planet, more advanced humans from a parallel universe might have found a way to cross the divide, with their transÂient presence in our own universe causing UFOs.
