Kevin A. & Patrick J. Casey are the American authors of a series of papers currently available on the academia.edu website(a), which are concerned with a globally catastrophic event that occurred 13,000 years ago. providing them with a title of ’13K Theory’. The kernel of their theory is that originally the Earth had two moons that at some later point collided, producing our current Moon, while the remnant of the second one eventually exploded over North America kick-starting what we refer to as the cooler Younger Dryas period.
They claim that this event wiped out megafauna, altered the Earth’s axis and created our mountains, the Earth being generally flat before the dramatic episode! They are adamant that it was not a comet or asteroid that caused the devastation, and so clash with the work of Richard Firestone and his colleagues.
Their final paper is entitled Atlantis Revisited(b), in which they nominate Rockall as being ‘by far’ the most likely location of Atlantis. They also claim that the war between the Atlanteans and the Greeks took place before the 13K Event. Enjoy.
Stuart L. Harris is an American researcher, self-described as an linguist, historian and archaeologist. He has contributed over eighty papers to the Migration & Diffusion website(a) and dozens to the Academia.edu site(b). He has touched on a wide variety of subjects; from Comet Encke to Glozel and Newgrange to Noah’s Flood. Although I am not a linguist, I think that that Harris’ penchant for ‘finding’ evidence of the Finnish language in locations as far apart as Dacia, Gaul, Teotihuacan and Hawaii is highly questionable, but I shall leave it to others, more skilled than I, to comment further.
Inspired by Felice Vinci, Harris has promoted the idea of Troy in Finland, but until lately he had not directly addressed the question of Atlantis, but in recent private correspondence with me, he has claimed that Plato’s lost island had been situated in the vicinity of Rockall and destroyed around 9577 BC. He later published these ideas in a number of papers on the Academia.edu website(c-f) in which he proposed that a close encounter with Nibiru (Marduk) that resulted in a number of its satellites impacting the Earth, causing devastation which included the demise of Atlantis. He also equated Nibiru with Marduk. The article contains a lot of wild speculations including the suggestion that Nibiru on a return to Earth in 9417 BC, lost another of its satellites, which became our Moon!
Nibiru was a Sumerian astronomical term used to describe a planetary body that periodically approached Earth. This account was hijacked by the late Zechariah Sitchin to construct his Planet X theory in which he claimed that this planet had an orbit that took it to the outer limits of the solar system returning every 3600 years to the vicinity of Earth. Sitchin claimed that during one of these visits some of its inhabitants came to earth and become the ‘gods’ of the Sumerians. However, Sitchin failed to explain how the inhabitants of this Planet X survived the lack of heat and light that it would have had to endure as it moved away from the proximity of the Sun. For us inhabitants of Earth, a drop of just a few degrees is fatal.
However, Emilio Spedicato has a radically different and certainly more rational view of this Sumerian planet. He ascribes a much shorter orbital period of 20 years to Nibiru and claims that close encounters with this planet (and its satellites) had a dramatic physical effect on the prehistory of our planet including the capturing of our Moon, the destruction of Atlantis and later the biblical Exodus! His scenario has elements that can be traced to Velikovsky, Ackerman and Hörbiger.
Robert Solarion was a keen follower of Immanuel Velikovsky and like him was convinced that in the first and second millennia BC the Earth had suffered a catastrophic Pole Shift as a result of a close flyby of a large extraterrestrial body or bodies. Velikovsky identified these as Venus and Mars, but Solarion differed, suggesting that it was the putative Nibiru!(h)
Professor Spedicato’s November 2012 paper, From Nibiru to Tiamat, an Astronomic Scenario for Earliest Sumerian Cosmology, can be read or downloaded from the excellent Diffusion and Migration website(a). A number of his other papers can be found on the same website and are certainly worth studying.
In sharp contrast to the serious work of Spedicato, for the past couple of years, we have been subjected to a barrage of silly articles(b) linking Nibiru with the promised 2012 global catastrophes ‘predicted’ by the Mayan calendar.
A debunking of both Sitchin’s scholarship and the existence of Nibiru has been offered by a number of sites(c).
However, some people, such as David Meade (a pen-name) who describes himself as a ‘Christian numerologist’ predicted that Nibiru would collide with Earth on September 23, 2017! When this did not happen he moved the event to October, but again nothing happened. But he persisted and subsequently moved our demise to March 2018, then April, with a final suggestion for that year of between May and December(d).
In early 2021, an article on the BBC offered a potted history of the search for Planet X from the time of Percival Lowell until now(i). Although, Planet X has proved elusive, “either way, the search for the legendary ninth planet has already helped to transform our understanding of the solar system. Who knows what else we’ll find before the hunt comes to an end.”
Nils Olof Bergquist (1897-1989) was a Swedish engineer with an interest in ancient history. In 1954 he published The Moon Puzzle which is probably a reworking of his 1946 Swedish publication. In it he describes a very close encounter of the earth with a large extraterrestrial body some millions of years ago. As it grazed the earth it caused the ejection of a large mass from what is now the Pacific Ocean. This mass became our Moon.
Although his theories differ in many respects from those of Hörbiger, Bergquist never once referred to Hörbiger’s ideas, which were still popular at that time. Berquist was content to link together the Deluge of Genesis, the Atlantis story and the Nordic Niflhem saga.
In 1971, he published, in Swedish, Ymdogat-Atlantiswhich looked at Atlantis in the light of Norse mythology. He also studied The Oera Linda Book and in the end endorsed the Dogger Bank as the most likely location of Atlantis.
Younger Dryas is also known as Dryas III was a mini Ice Age that lasted from around 10,700 BC until around 9600 BC. It is named after a wildflower called Dryas octopetala that flourished during this relatively short period. In Ireland, the period is known as the Nahanagan Stadial and in Britain as the Loch Lomond Stadial. For about thirteen hundred years the glaciers had been slowly retreating until within a short timespan temperature dropped and they began to advance again. The cause of this cooling is not absolutely clear. One view is that a sudden release into the North Atlantic of vast quantities of freshwater that had been contained by huge ice dams is assumed to have closed down the Gulf Stream, resulting in a twelve hundred year lowering of global temperatures. There is evidence that the change only took one or two decades. The same threat is said to exist today with the possibility of the melting of the Greenland ice cap. It also seems that this YD cooling ended with the same rapidity.
A recent application of archaeoastronomy by Martin Sweatman and Dimitrios Tsikritsis led them to conclude that the carved symbols at Göbekli Tepe recorded an encounter involving the explosion or impact of part of Encke’s Comet around 13,000 years ago, which triggered the Younger Dryas Event that provided the impetus for the Neolithic Revolution. Sweatman later expanded their work in his book Prehistory Decoded  and in an article on the Ancient Origins website(k).>In June 2021, Sweatman had a paper entitled ‘The Younger Dryas impact hypothesis: review of the impact evidence’ published in the journal ‘Earth Science Review’ of the University of Edinburgh(u).<
Kevin A. & Patrick J. Casey maintain that a globally catastrophic event occurred 13,000 years ago(j). The kernel of their theory is that originally the Earth had two moons that at some later point collided, producing our current Moon, while the remnant of the second one eventually exploded over North America kick-starting what we refer to as the cooler Younger Dryas period. They are adamant that it was not a comet or asteroid that caused the devastation, and so clash with the conclusions of Richard Firestone and his colleagues.
A completely different view is expressed in Rod (Carl) Martin’s latest book , where he proposes that the Younger Dryas ended as a result of a catastrophic event. Is it possible that there were two cataclysmic episodes? John Ackerman, a keen follower of Immanuel Velikovsky claims that there were two such events related to “the capture of the Moon into its current orbit,” marking the beginning and the end of the Younger Dryas period(q).
A somewhat technical paper, published in July 2020, challenges the comet impact theory because of geochemical anomalies, Instead, they argue that the YD event was a consequence of volcanic activity(s), rather than an impact!
In 2015, a paper constraining the impact date to within 100 years using Bayesian statistical analyses, now proposed as 12,835 -12,735 years ago(h).
Coincidentally, Emilio Spedicato independently arrived at the conclusion that it was a cometary impact in the North Atlantic that was responsible for the Younger Dryas. Subsequently, when temperatures rose again it resulted in the flooding of vast areas of low-lying landmasses that in Spedicato’s opinion included Atlantis, which he locates in Hispaniola.
Conflicting evidence regarding the possibility of the Younger Dryas being caused by such an impact is impartially outlined on the internet(a).
The November 2013 issue of the BBC Focus magazine (p.30) had a brief article on the impact theory, noting that the northern hemisphere saw a drop of as much as 15°C around 11,000BC. In the absence of a suitable impact crater of the right age, there is still much scientific scepticism(b).
However, in early 2017, further possible evidence of an impact at the start of the Younger Dryas was offered by a team led by Christopher Moore of the University of South Carolina, when they identified a distinct layer of platinum in the soil that coincided with the start of YD. Commenting on this anomaly Moore noted that “Platinum is very rare in the Earth’s crust, but it is common in asteroids and comets.”(e) In 2019, Moore published further data(m) supporting the extraterrestrial impact theory, based on studies carried out on sediments, which date back 20,000 years, from White Pond Lake, situated in southern Kershaw County, South Carolina. “Other examples of excessive platinum grains have been found across Europe, western Asia, Chile, South Africa(r) and North America.” (n)
In early 2018, two papers were published online(i), reinforcing the YD impact theory and adding evidence that the event resulted in a conflagration that “may have consumed ~10 million km2, or ~9% of Earth’s terrestrial biomass.” Related to this is a paper by Andrew Collins that draws attention to the ‘Usselo horizon’, a charcoal-rich layer of between 1 and 8 inches, found on all continents, indicating widespread fires, now dated to 12,900 years ago(l).
Ice cores from Greenland indicate a further cooling period circa 6200 BC that may be related to the abandonment of many Neolithic settlements during this period. Other periods of abrupt climate change have been identified from 3800 BC to 3500 BC and 2800 BC to 2000 BC.
The fact that Plato’s apparent date for the demise of Atlantis, circa 9600 BC, roughly corresponds with the current, best estimate for the date of the Younger Dryas is interesting but unfortunately not conclusive proof of any direct connection. In the absence of any supportive archaeological evidence, a linkage between Atlantis and the Younger Dryas will have to remain a matter of faith rather than fact. Interesting but inconclusive.
>A short paper by John Patrick Hill offers a theory that requires more than faith to accept it; he wrote “Just over 12 thousand years ago, the world was struck by an immense meteor group. It destroyed all of North America and much of Europe and went weIl beyond……… I found proof to support that the creators of the Giza Three and Stonehenge used the Barringer Crater in Arizona as part of the geometry for their for their massive structures.” Later he reveals that at “Giza, when one takes the distance between the outside corners of the three large pyramids there, that distance is equal to 0.72 miles, the exact distance (diameter) at Barringer.” An expanded version of his paper is available online.(t)<
Recent discoveries in northern Sudan of dozens of skeletons, the majority of whom were apparently killed by flint-tipped arrows, have led to the suggestion(c) they were the result of food shortages resulting from the Younger Dryas that in turn led to warfare over diminished food availability.
I note that Robert Schoch claims that there is no evidence to support the Younger Dryas impact theory, instead, he believes that “it was most likely due to reduced solar activity at that time, a solar shut-down.”(o) Schoch’s wide-ranging critique has been refuted by the Comet Research Group.(p)
The Deluge is a term often used when referring to the biblical flood of Noah. It might perhaps be more accurate to use the plural, as there is evidence of several large-scale catastrophic inundations within the memory of man. The Noachian deluge has been the subject of continuous debate: was it real or pure fantasy, was it local, regional, or global, and is the Ark to be found on Mt. Ararat.
The most recent controversy concerns a Babylonian tablet which, unlike the biblical record, describes an ark 70 metres in width and round in shape(c)(e). This would have been recorded a thousand years before the Genesis story was written down. Understandably, this has caused the knickers of some fundamentalist Christians to be seriously twisted! The discovery has now been expanded on by Irving Finkel in The Ark before Noah. Another eye-catching theory is that of Thomas J. Krupa (1930- ), author of Biblical Flood: Noah’s Ark and the Star of David, in which he claims that the keel of the Ark was shaped like the Star of David! Equally radical is the result of a high-tech study of fragments of the Dead Sea Scrolls which suggest that Noah’s Ark was pyramidal in shape(j)! Commenting on this report, Jason Colavito has pointed out that the concept of a pyramid-shaped ark is not new(k).
A sceptical 2019 article has looked critically at many aspects of the story of the Ark, including the most commonly offered Turkish site as the resting place of the Ark – “One of the most famous supposedly-Noah’s-ark sites is the admittedly very boat-looking Durupinar site in the Mount Tendurek area in Turkey. According to Atlas Obscura, the site was exposed in the late 1940s after a series of earthquakes and storms.“(t)
A life-sized replica of Noah’s Ark was due to cross the Atlantic Ocean from Holland in the summer of 2016(i). It was built over a four-year period by a carpenter, Johan Huibers, completing it in 2012. It is 410 feet long, 95 feet wide, and 75 feet tall. It weighs 2,500 tons and is said to hold more than 5,000 people at any one time. However, there is no provision for live animals! The replica was sold to Aad Peters, a Dutch artist, who in 2019 brought it to Ipswich in Britain. Unfortunately, it has been impounded by the authorities there as it lacks the appropriate paperwork to permit it to leave. There are also serious concerns regarding its seaworthiness and is also clocking up port fees of £500 a day(x)(y).
An interesting overview of traditional as well as modern thinking regarding the possible historical reality behind the Deluge of Genesis is presented(f) by Robert Squillace on the New York University website.
Even more radical is the claim by Hebrew scholar Richard Seary that the Ark never actually existed, but that conventionally accepted understanding of the Genesis text is the result of a number of incorrect translations(d). One example is that there is no such material as gopher-wood and that the word ‘gofer’ means lava!
The Flood of Noah is an echo of the Babylonian Gilgamesh epic, which in turn has a resonance with the deluge story of Manu in Indian mythology. If all three relate to the same event it would be of interest to discover if there was a shared origin.
Many Atlantologists have sought to link the Deluge with the inundation of Atlantis. Egerton Sykes was a keen supporter of the idea. Joseph S. Ellul has interpreted the biblical story to support the idea of a landbridge at Gibraltar that eventually collapsed when the waters of the Atlantic rose after the last Ice Age.
Ellul maintained that Genesis 7:11 ‘All the springs of the Great Deep broke through’ is a reference to the percolation of the Atlantic waters, through the Gibraltar dam, that eventually led to its collapse as the sea level rose or was shattered by seismic or tectonic movements. I find it hard to accept this, because the pressure that is exerted by the Atlantic, would have rapidly changed any such seepage into a major breach and the subsequent collapse of the dam. Gerhard F. Hasel, Professor of Old Testament and Biblical Theology offers a more conventional interpretation of “the fountains of the great deep” in a paper with the same name(h).
Alexander and Edith Tollman link the Noachian Deluge with the consequences of a cometary impact in 7552 BC. On the other hand, G. F. Dodwell the Australian astronomer, after studying ancient gnomons, concluded that it was a worldwide catastrophe in 2345 BC that altered the earth’s tilt, leading to the Deluge. This is comparable with the 1696 claim by William Whiston that the earth had an encounter with a comet in 2346 BC, which caused the Flood of Noah. Emilio Spedicato advocates 3161 BC as the date of the biblical deluge(l). which has also been endorsed by Stuart L. Harris(n).
Jeffrey Goodman, the controversial author of Psychic Archeology , maintains that “Noah’s Flood was really a tsunami caused by a comet” and supports this contention with a retranslation of Genesis 7:11 (w).
On a more controversial level, Donald Patten and Samuel Windsor present evidence for a series of close encounters between Mars and the Earth during the 1st millennium BC. David Rohl, the Egyptologist, dates Noah’s Flood at 3114 BC and links it with the climatic consequences of a major catastrophe in the Aleutian Islands.
Ancient flood stories are to be found around the world with a remarkable similarity of detail. It is worth pointing out that none of these legends ever recount the ‘hero’ of their particular tale returning to his former home. One simple explanation for this might be that the original homelands no longer existed. This would not normally be the case if the floods in question were tidal, storm-driven, or even giant tsunamis. However, if the inundations were the result of rising sea levels, resulting from the melting of Ice Age glaciers, we could expect two principal effects. The first would have been the gradual submergence of all low-lying flood plains that are now identified as continental shelves. Two of the best known of these would be the Sunda Shelf (Sundaland) and the area stretching from the west coast of mainland Europe across the North Sea encompassing the British Isles and into the Atlantic beyond Ireland. The second effect would have been the dramatic inundation of valleys and basins protected by low land bridges or dams. Again, we have examples, some debatable, such as, the Baltic, the Red Sea, the Persian Gulf, the Black Sea, the Mediterranean and perhaps the Caribbean, the Gulf of Mexico, and the Sea of Japan.
When Ryan & Pitman(r) published their 1997 theory that around 5600 BC, the Black Sea had been flooded by water from the Aegean breaching the Bosporus, it did not take long before it was speculated that the event was reflected in the story of Noah’s Deluge. With little delay, strong objections to the idea were raised by many others(s). Perhaps relevant to the subject is the claim that the flow of water was instead from the Black Sea into the Aegean, a view expressed by Nick Thom in The Black Sea Flood .
It is very interesting that so many of the deluge stories include a scenario where the ’hero’ is warned beforehand of the impending doom. To me, this would make sense that where a land bridge was threatened by gradually rising waters on one side, simple observation would have provided adequate time to warn those at risk on the other side.
The flooding of all these worldwide locations would have occurred quite slowly over an extended period following the last Ice Age, possibly providing the basis for the widespread existence of these flood myths.
Nevertheless, there is one rather disturbing element to be found alongside some of the flood myths, namely that the deluge event was concurrent with the sun seemingly standing still, and in some cases, it is recorded that the Moon also appeared to stop(o)(p)! One explanation on offer is that it is a reference to an eclipse(q). This might be acceptable if it was compatible with other myths from different parts of the world, which does not appear to be the case. Furthermore, it does not explain the association of the stopping of the sun with the global deluge. A very close encounter between the Earth and another large celestial body might.
Nick Thom, an Engineering lecturer at Nottingham University, has written The Great Flood  which gives an overview of Flood myths but more importantly identifies the emptying of glacial Lake Agassiz around 6250 BC as the mechanism which caused a tilting of the Earth, which in turn generated a global deluge remembered by the survivors in myth and later recorded in scriptures.>This is also fully outlined in a lengthy paper titled, A Re-interpretation of the 8.2ky BP Event(z).<
A website with a huge collection of worldwide flood myths is available online(b). However, one omission from all such collections is a contribution from Egypt who inexplicably has no such tradition, apart from the predictable annual flooding of the Nile. However, there is the Egyptian story of Hathor/Sekhmet(u)(v) who flooded the land with blood, which some may interpret as a mythological code for water!
Greek mythology includes reference to three major floods affecting Greece, those of Ogyges, Deucalion, and Dardanus(o). Plato’s story of Atlantis makes mention of a number of major floods during the ‘9,000’ years following the war with Atlantis, one of these being the flood of Deucalion. However, it may be worth mentioning that with so many ancient cultures having recorded flood myths, Egypt is notable for having none!
Stephen Oppenheimer mentions three sudden ice-melts, 14,000, 11,500, and 8,000 years ago that would have had a global effect. It should be noted that the earliest date is close to the apparent date given by Plato for the destruction of Atlantis.
As I see it, we are left with two explanations for the global flood myths, either a close encounter with an extraterrestrial body that created a mega-tsunami that was on such a scale that it swept around the globe, perhaps a number of times before dissipating, or the melting of the Ice Age glaciers produced the cyclical bursting of ice-dams and landbridges and the inundation of vast areas of low-lying land. I’m inclined to believe that the balance of probabilities favours the latter explanation, although I find it difficult to accept that gradual deglaciation would have generated floods that ‘covered mountains’ (Gen. vii.19)!
Kirk Kirchev in a recent (April 2018) two-part article(m) “offers a unifying scientific hypothesis that connects diverse ancient flood myths with mainstream scientific fact.”
T. R. Holme has an interesting article(g) on the flooding of the Black Sea and the migration from the region that resulted. He also links that event with the work of the late Marija Gimbutas (1921-1994).
(d) Fortean Times, April 2014, p.55
Hanns Hörbiger (1860-1931) was an Austrian mining engineer by profession and in his spare time was an amateur astronomer. Today, he is probably better known as the father of the actors Paul and Attila Hörbiger.
By gazing at the moon he became convinced that he was looking at a bright outer layer of ice. Hörbiger published his “Doctrine of Eternal Ice” around 1913 in a book co-authored with a schoolteacher named Philip Fauth. Hörbiger proposed an early form of catastrophism that saw the Earth capture a number of moons in succession. Periodically, each of these moons disintegrated and as they spiralled to earth producing enormous ‘ice showers’ followed by meteors of iron. He saw the effects of these impacts as the source of Flood myths and claimed that when our current Moon was captured around 9500 BC it triggered earthquakes that led to the destruction of Atlantis. His theories were hailed in Germany during the 1930’s and 1940’s and officially backed by the Nazis (see Ahnenerbe). Heather Pringle notes[0032.180] Hitler’s personal support for Hörbiger’s theories.
>In 1966, Egerton Sykes wrote that “in addition Hitler requiring a Teutonic cosmology as well as a Germanic Europe, adopted Hoerbiger’s hypothesis, probably one of the few sensible acts that the Nazis ever made”(w).<
There was a Viennese Hörbiger Institute for World Ice Science founded in 1932(p). Their publication Mitteilungen had two volumes published from 1941 to 1944 and a third volume 1971-1976(o).
An interesting 1949 report by Manfred Reiffenstein describes the problems that the Hörbiger Institute had encountered with the Nazis from 1938 onwards. While efforts were made to close the Institute down and transfer its archives to Himmler’s Ahnenerbe organisation, this was prevented by the efforts of Hörbiger’s sons(s), which might be considered an example of postwar revisionism.
A recent paper by Graham Holton explicitly accuses Hörbiger of ‘archaeological racism’, along with Edmund Kiss, Posnansky and others in the Ahnenerbe(t).
His ideas were adopted and developed further by Hans Bellamy in a number of his books. During the first half of the 20th century, many beyond the Nazi realm frequently referred to Hörbiger’s moon theory as authoritative.
Hörbiger refused to accept the evidence that his ‘icy’ moon had a daytime temperature of 100°C. Followers of Hörbiger existed in Germany, Britain and France after the war, until an actual landing on the Moon demonstrated that it was composed of neither ice nor cheese.
A number of other writers developed theories that were variations on Hörbiger’s ideas. 1954 saw the publication of The Moon Puzzle by the Swedish engineer, N.O. Bergquist, in which he suggested that earth had a close encounter with a planetoid which caused the ejection of a large amount of matter, which became our Moon leaving a huge scar we call the Pacific. Although many details of Berquist’s theory differ greatly from Hörbiger’s, he never refers to the then widely supported views of Hörbiger.
In 1955, G. Demortier published a theory of cosmic catastrophe that was somewhat similar to Hörbiger’s. However, couple of years earlier, doubts were beginning to emerge regarding aspects of Hörbiger’s theories as our cosmological knowledge advanced(u), nevertheless in the same magazine Edmund Kiss attempted to justify Hörbiger’s idea of an ice-covered Moon!
It is even more astounding that as late as 1964, Egerton Sykes, the leading British atlantologist of the day, was still clinging to the concept of an ice covered lunar surface. In fact re-reading the old editions of Sykes’ Atlantis newsletter, I am amazed at the number of contributors that offered so many articles based on Hörbiger’s flawed ideas. My personal view is that having read Sykes’ newsletters, he can only considered a gullible British gentleman.
Egerton Sykes founded and promoted an English post-war Hoerbiger Institute through his Atlantis magazine(q). In March 1948 Bellamy contributed a short article (Hoerbiger Monograph No. 1. 2nd Edition)(n) to the newsletter, reiterating his support for the idea that the capture of our moon led to the destruction of Atlantis.
>Commander E.H. Nutter, a Royal Navy engineer, who contributed many articles to Sykes’ Atlantis magazine was considered “the leading technical authority on the Hoerbiger Theory in England” in the 1950’s.(v)<
Uwe Topper, the controversial German researcher has continued to support much of Hörbiger’s ideas. Additionally, in 2003, Gary Gilligan, a prominent catastrophist, first proposed that our Moon had been captured around 2000 BC, which he has now revised to 1200 BC(I)!
The August 2010 edition of the BBC’s Focus magazine (p.81), informs us that the Moon is moving away from Earth at a rate of 3.8cm per year, completely destroying the foundation of Hörbiger’s basic theory. The 9th Nov. 2011 issue of New Scientist published further evidence supporting this view(h), with further claims that this recession will reverse in the very distant future as the Earth’s rotation slows(r).
In the 17th century Johannes Kepler demonstrated that when an object’s orbital velocity increases, its orbital radius will expand; thus, the Moon slowly recedes from Earth(d). This idea was discussed further in a BBC documentary broadcast on Feb.1st 2011(b).
Nevertheless, updated Moon capture theories have been developed since Hörbiger. Emilio Spedicato has published a brief overview of recent contributions on the subject as well his own version(c), dating it to around 9450 BC, triggering the end of the Ice Age and the destruction of Atlantis!
It was long accepted wisdom that a moonless earth would have made the development of complex life more difficult because of greater climatic fluctuations. However, a new study challenges this, calculating that Jupiter together with other factors would minimise the effect of not having our satellite(g)
The story of lunar history took an unexpected turn in 2011 when the journal Nature published a paper by planetary scientists Erik Asphaug of the University of Santa Cruz and Martin Jutzi of the University of Berne who proposed that originally the Earth had two moons that later collided and formed our present satellite(e). At the end of 2011 two NASA lunar probes were launched(j) which may resolve this particular question.
In America, the WEL-Institute is dedicated to investigating Hörbiger’s ‘World Ice Theory’(k). I note that the U.S. is also home to associations concerned with both a Hollow Earth(l) and a Flat Earth(m)!

Professor Nikolay Bonev (1898-1979) formerly held the chair of Astronomy at the University of Sofia, in Bulgaria, favoured an Atlantic location for Atlantis and published a number of papers in the mid-20th century on the subject. He was inclined to the idea of an asteroid strike or close fly-by as the primary cause of the destruction of Atlantis(b). He considered that an asteroid approaching the earth would have caused a tide of enormous magnitude that would have created incredible devastation as it either followed its course as the asteroid either flew past or reacted to a massive sea impact. Bonev specifically favoured the asteroid Ceres as the culprit.
Bonev, caused a stir in 1961 when he expressed the view that our Moon had once been an independent planet(a) 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. His views had echoes of Hans Hoerbiger’s discredited captured moons theory. At the time scientists rejected Bonev’s claim as unsubstantiated by evidence, but since then we have discover the ongoing mega-eruptions on Jupiter’s moon, Io, which is slightly larger than our Moon. No effect on Io’s orbit has been recorded.
