A note on digital ethics: As of this writing, the copyright status of Our Mysterious Spaceship Moon remains murky. The original publisher, Sphere Books, has long since reorganized. Because the book is out of print, many libraries do not carry it.
Why is there such high demand for a PDF of this 1970s book? The answer lies in the intersection of curiosity, nostalgia, and the desire for alternative perspectives.

While the moon is less dense than the Earth, geological studies indicate a natural formation, likely from a collision between Earth and another celestial body (the "Giant Impact Hypothesis").
Wilson, like other proponents of "ancient astronaut" theories, looks to human history.

This article explores the core claims of Wilson’s book, its cultural impact, and why the search for a "PDF" version remains active among fans of alternative history and unconventional science. What is "Our Mysterious Spaceship Moon"?

From a scientific standpoint, the "Spaceship Moon" hypothesis, and Wilson's book by extension, is firmly in the realm of pseudoscience. Astronomers like Suniti Karunatillake and Dr. Karen Masters have stated that based on analyses of the moon's size, mass, geology, and gravitational field, "the scientific evidence indicates that the Moon cannot be hollow". The ringing effect, for example, has more mundane explanations related to the moon's unique, fractured, and water-depleted crust, which efficiently transmits seismic waves.
