The hypothesis has been advanced by ufologists such as Meade Layne,[2] John Keel,[3] J. Allen Hynek, and Jacques Vallée.
[4][1] Proponents of the interdimensional hypothesis argue that UFOs are a modern manifestation of a phenomenon that has occurred throughout recorded human history, which in prior ages were ascribed to mythological or supernatural creatures.
In this tradition, the concept al-ghayb refers to the hidden, unseen, and invisible, and encompasses a range of important phenomena in Islam and in the everyday lives of Muslims.
[2] Layne claimed to be in telepathic communication with "people in the saucers", arguing "it is possible for objects to pass from an etheric to a dense level of matter and will then appear to materialize.
"[9] The prior year, it had been reported that Layne consulted a medium who relayed communications from a "space ship named Careeta" that came to Earth from 'an unidentified planet'.
[13][14] In his 1970 book UFOs: Operation Trojan Horse, Keel argued that a non-human or spiritual intelligence source has staged whole events over a long period of time in order to propagate and reinforce certain erroneous belief systems.
[13][additional citation(s) needed] Keel used the term "ultraterrestrials" to describe UFO occupants he believed to be non-human entities capable of taking on whatever form they want.
[15] Jacques Vallée, a student of Hynek's, served as the inspiration for the French researcher portrayed by François Truffaut in the film.
The bulk-beings[21] who built the tesseract inside the supermassive black hole Gargantua are later revealed to be future humans who have evolved to exist in five dimensions.
