From Wikipedia, the free encyclopedia

The Spaceship Moon Theory, also known as the Vasin-Shcherbakov Theory, is a pseudoscientific theory that claims the Earth's moon may actually be an alien spacecraft. The theory was put forth by two members of the then Soviet Academy of Sciences, Michael Vasin and Alexander Shcherbakov, in a July 1970 article entitled "Is the Moon the Creation of Alien Intelligence?".^{[citation needed]}

Vasin and Shcherbakov's thesis was that the Moon is a hollowed-out planetoid created by unknown beings with technology far superior to any on Earth. Huge machines would have been used to melt rock and form large cavities within the Moon, with the resulting molten lava spewing out onto the Moon's surface. The Moon would therefore consist of a hull-like inner shell and an outer shell made from metallic rocky slag. For reasons unknown, the "Spaceship Moon" was then placed into orbit around the Earth.^{[citation needed]}

In 1975, Don Wilson published "Our Mysterious Spaceship Moon" in which he compiled what he considered supporting facts for this theory.^{[citation needed]}

Criticisms

Suniti Karunatillake and Dr. Karen Masters have both researched and based on continuing analyses of its size, mass, geology and gravitational field, both believe that the scientific evidence indicates that the Moon cannot be hollow.^[1][2]

Spaceship Moons in literature

In the series by Science fiction author David Weber, Heirs of Empire, the moon is in fact a giant space ship arriving 50,000 years ago. The population of Earth are the descendants of the crew of the ship, who abandoned it after it was damaged in a mutiny. In these books the moons are artificial constructs which are given a rocky outer coating as a form of camouflage. The three books in the series are Mutineers Moon, The Armageddon Inheritance and Heirs of Empire.
