The author, Albert Budden, has reached the conclusion that UFO sightings and alien encounters are caused by an electromagnetic field. This hypothesis, known as electro-staging, explains this phenomenon in terms of electromagnetic pollution.

The author reasons that human states of mind can be altered by natural changes in the Earth's magnetic fields. Therefore Budden has presumed that UFOs and aliens can be explained in the same way.

The author based his theory on a publication produced by the Society for Psychical Research written by Andrew MacKenzie and called Hauntings and Apparitions

Budden was surprised to learn that apparitions behaved in the same manner as UFO related entities therein. Budden also uses electromagnetic energy to explain Men in Black, out of the body experiences, altered states of awareness, time distortion, time lapse, visions, trances, and other anomalous occurrences.

The author also discusses identified atmospheric phenomena (UAP) as critical to understanding the UFO phenomena. Two examples of UAP's are ball lightning and Earth lights.
