Abstract
This two-part essay addressed a two-part question: “If extraterrestrial life exists, then where are they?” and “Is interdimensional travel possible and, if so, how?” Drawing upon the insights of Jane Roberts’s philosophical psychology, the following thesis is advanced and defended: Alternate life planes and reality systems exist and make contact with the spacetime structure of our own physical universe at coordinate points through which non-human intelligent beings may travel that can be scientifically investigated utilizing both objective instrumentation and subjective tools. Part 1 examined evidence for the physical existence of unidentified aerial phenomena (UAP) and interdimensionality as a scientific/metaphysical hypothesis concerning their origin. Characteristic features of interdimensional planes and the mechanics of travel between planes were described. Part 2 continues the discussion by describing how interdimensional travel might be accomplished via out-of-body conditions of consciousness with the mechanical assistance of coordinate points and scientifically investigated. The essay concludes by examining the implications and applications that such an investigation can have for informing the study of other issues, anomalies, and fields of study.
