The Moon has little connection with Plato’s Atlantis story apart from the more extreme speculations of some writers. One of the wildest is that the Atlanteans had established a research facility on the Moon(a), an idea rivalled by that of Alan Butler & Christopher Knight in their book, Who Built the Moon, in which they propose that the Moon was ‘constructed’! This idea has now been revived by Rob Shelsky. In 1965, the Umland brothers proposed that the Moon was a communications relay station for the Maya to make contact with their home planet!
In 1970, Michael Vasin and Alexander Shcherbakov, of what was then the Soviet Academy of Sciences, advanced a hypothesis that the Moon is a spaceship created by unknown beings.(k)
The idea that the Moon was to some extent hollow was given impetus in the 1970’s, when a study of moonquakes revealed that the Moon ‘rang like a bell’ (i). Now, nearly half a century later, Wallace Thornhill, a leading Electric Universe proponent, has endorsed the hollow Moon idea and seems sympathetic to the idea of a hollow earth. This was expressed at a recent EU conference and be viewed at the 40-minute mark of a YouTube video.(j)
The origins of the Moon have also been the subject of extensive controversy with one side claiming that it had been ‘captured’ by the earth, while the other extreme argues that it had been ‘expelled’ from our planet. The expulsion theory posits(b) that a collision with another celestial body tore material from the Earth, which in time became our Moon(h). Nils Olof Bergquist writing in the 1940’s supported the expulsion scenario and had his original Swedish book on the subject translated into English as The Moon Puzzle.
The most radical of the captured moon school was Hanns Hörbiger, who proposed that there had been a series of Moon captures. Many of his ideas were adopted by H.S. Bellamy, who added that the capture of our current satellite had caused the destruction of Atlantis. Nikolay Bonev, the astronomer, caused a stir in 1961 when he expressed the view that our Moon had once been an independent planet(d) that had experienced violent volcanic eruptions that were powerful enough to have produced a ‘recoil’ effect, which nudged it towards our Earth’s orbit and was eventually captured as our satellite.
More recently Emilio Spedicato expressed similar ideas(c), claiming that material taken from another large extraterrestrial body around 9450 BC became our Moon, but that the event also led to the destruction of Atlantis. Stuart L. Harris has proposed(m) that the planet Nibiru had a close encounter with our Earth in 9577 BC that resulted in the destruction of Atlantis, followed by another visit in 9417 BC during which it lost one of its satellites, which became our Moon!
*The Moon controversies continue with the recent suggestion by Erik Asphaug, a professor of earth and planetary sciences at the University of California, Santa Cruz, who claims that originally the Earth had two moons that coalesced into a single satellite (n)!*
Gary Gilligan, the catastrophist, also supports the concept of moon capture but dated this event to as recent as 2000 BC(f) and then later advanced it to 1200 BC(g). Researcher, Mark Andrew commenting on Gilligan’s claims wrote that “Although Gilligan promises more evidence to come, his theory has to contend with the varied evidence of an earlier Moon, including the earliest known written myth of the Moon’s death and rebirth, the epic poem Descent of Inanna (dating from 1750 BC), and also the oldest known map of the moon (dating from 2800 BC).”(l)
Unexpectedly, the orbital speed of the Moon appears to vary on its trip around the Earth(e).

Mike Baillie is Emeritus Professor of Palaeoecology in the School of Archaeology and Palaeoecology, Queen’s University, Belfast. He is a dendrochronologist of world renown, who outlined in his recent book  the evidence for catastrophic encounters with asteroids or comets over the past five millennia that opened a whole new chapter in the search for the truth about our past. Baillie ascribes these events to 2354-2345 BC, 1628-1623 BC, 1159-1141 BC, 208-204 BC and 536-545 AD. He touches on a number of legendary and historical events such as the Deluge, the Exodus and King Arthur, but seems to studiously avoid any direct reference to Atlantis. Nevertheless, his theory in conjunction with the suggestions of writers such as Emilio Spedicato enhances the possibility of the destruction of Atlantis being a consequence of a more widespread catastrophe.
In 2004 it was revealed that a very large comet or asteroid, estimated to be ¾ of a mile in diameter, crashed into what is now Germany. The date is calculated at 200 BC, which coincides with one of Baillie’s dated catastrophes. A crater field stretching from the town of Altoetting to Lake Chiemsee is all that remains today.
Perhaps even more relevant to our study was a PowerPoint presentation(b) from Baillie to a Quantavolution Conference in Athens in 2011, which offered compelling evidence for a catastrophic event in 2345 BC. His data reinforces the work of George Dodwell who demonstrated with his study of ancient gnomons, decades earlier, that something dramatic happened to the rotational axis of the Earth in 2345 BC, which is possibly the same 2346 BC encounter with a comet proposed by William Whiston in 1696. At the same conference Baillie also presented evidence for dating the eruption of Thera to 1628 BC.
Baillie is also co-author with Patrick McCafferty of a fascinating work that reinterprets some of the heroes and gods of Celtic mythology as a coded account of our ancestors’ observation of a close encounter or impact of comets with the Earth. However, Baillie’s books should be read in conjunction with an equally compelling volume(a) by David Talbot and Wallace Thornhill who offer a complementary but rather than conflicting interpretation of early man’s perception of highly visible cosmic events. Talbot and Thornhill have linked ancient myths and thousands of petroglyphs with their view of an electric universe, where large-scale plasma phenomena were witnessed and recorded by preliterate man. Their book has drawn extensively on the work of Dr. Anthony Peratt, who has gathered and classified an enormous database of petroglyphs from all over the world that are apparently a record of celestial demonstration(s) of plasma physics.

Immanuel Velikovsky (1895-1979) was by profession a doctor of medicine, specialising in psychiatry. However, his fame is based on being arguably the most controversial catastrophist of the 20th century. He daringly proposed that the Earth had a number of close encounters with other planetary bodies that resulted in catastrophic consequences, including interference with the rotation of our planet. He speculated that Atlantis was probably destroyed during one of these cataclysmic events.
Some have seen the influence of Ignatius Donnelly’s Ragnarok, written seventy years earlier, in Velikovsky’s cosmic collision theories. In fact a number of commentators have noted how Velikovsky seemed reluctant to credit earlier writers, such as W. C. Beaumont and Johann Radlof (1775-1846)(b), with their contributions to the development of the theory of planetary catastrophism. Rens Van Der Sluijs has written an interesting two-part paper(d)(e) listing the catastrophists who preceded Velikovsky demonstrating a certain lack of originality on his part! Others take a more critical view of his ideas(g). In 1950, he responded to this criticism with a defensive piece(n), but I consider it inadequate as he continued to ignore the work of Radlof and Beaumont.
Van Der Sluijs has written a two-part(k)(l) article on Velikovsky’s radical views regarding Venus as a comet-like body and how Aztec sources support some of his contentions.
*Carl Sagan (1934-1996), was a well-known American astronomer, author and lecturer. He is considered a leading debunker of Velikovsky’s theories. He devoted much of his Broca’s Brain  to this end. Charles Ginenthal (1934-2017) produced an extensive rebuttal of Sagan’s criticisms in Carl Sagan & Immanuel Velikovsky .*
Velikovsky was initially inclined to link the disappearance of Atlantis with the eruption of Thera, but later came to support a location between the Azores and the Mid-Atlantic Ridge(i). He was an early questioner of Plato’s figure of 9,000 years for the age of Atlantis, suggesting that it was exaggerated by a factor of ten[0037.152]. ”Whatever the source of the error, the most probable date of the sinking of Atlantis would be in the middle of the second millennium, 900 years before Solon, when the earth twice suffered great catastrophes as a result of ‘the shifting of the heavenly bodies.’ These words of Plato received the least attention, though they deserved the greatest.”
Velikovsky offered intriguing evidence that on least one occasion the early Egyptians experienced the sun rising in the west and setting in the east(q)! His other major contribution was in his questioning of the accepted Bronze Age chronologies of the eastern Mediterranean. Later writers, such as David Rohl and Peter James have built on his chronology work, while Gary Gilligan has added support for Velikovsky’s planetary theories as well.
One website(a) provides us with a considerable amount of Velikovsky’s unpublished work, while another offers an encyclopedia of his work(c). A more general German site(f), in English, is also worth a visit.
The three of Velikovsky’s most popular books as well as some of his lesser known papers are available as pdf files(j)(m).
Jan Sammer was an assistant to Velikovsky (1976-1978) and an archivist and editor for the Velikovsky Estate (1980-1983). He advises us that he was involved in the completion of Velikovsky’s unpublished book, In the Beginning, which can be read online(h).
In 2012, Laird Scranton, published The Velikovsky Heresies, in which he reviews Velikovsky’s controversial theories in the light of scientific discoveries since his death. Not unexpectedly, Scranton does find evidence that supports some of Velikovsky’s contentions.
Some readers may wish to see a video by Wallace Thornhill, of Electric Universe fame, in which he discusses Velikovsky’s Astrophysics (o). There are a number of free papers and books, including some Velivovskian material, available online(p).
