Speculative cutaway model of a Spaceship Moon Lunar seismology experiments since then have shown that the lunar body has shallow moonquakes that act differently from quakes on Earth, due to differences in texture, type and density of the planetary strata, but there is no evidence of any large empty space inside the body. On November 20, 1969, Apollo 12 deliberately crashed the Ascent Stage of its Lunar Module onto the Moon's surface NASA reported that the Moon rang 'like a bell' for almost an hour, leading to arguments that it must be hollow like a bell. This phrase was brought to popular attention in March 1970 in an article in Popular Science. The Moon was described as "ringing like a bell" during some of those quakes, specifically the shallow ones. The Moon rang like a bellīetween 19, seismometers installed on the Moon by the Apollo missions recorded moonquakes. The Earth's upper mantle and crust are less dense than its core. One explanation of this discrepancy is that the moon may have been formed by a giant impact which ejected some of the early Earth's upper crust into its orbit. The moon's mean density is 3.3 g/cm 3, whereas the Earth's is 5.5 g/cm 3. The fact that the Moon is less dense than the Earth is advanced as support for it to be hollow. The concept of the Moon as a spaceship is often mentioned as one of David Icke's beliefs. īoth Hollow Moon and Hollow Earth are now considered to be a fringe theories or conspiracy theories. Gardner cited Wells's speculation of a Hollow Moon as support of the Hollow Earth theory. Wells borrowed from earlier fictional works that described a hollow Earth, such as the 1741 novel Niels Klim's Underground Travels by Ludvig Holberg.

The concept of hollow planets was not new The first discussion of a Hollow Earth was by scientist Edmond Halley in 1692. Wells wrote about a hollow moon in his 1901 book The First Men in the Moon. The suggestion of a hollow moon first appeared in science fiction, when H. It is often called the Spaceship Moon hypothesis and often corresponds with beliefs in UFOs or ancient astronauts. The Hollow Moon hypothesis is the suggestion that the Moon is hollow, usually as a product of an alien civilization. 2.3 Vasin-Shcherbakov "spaceship" conjecture.
