George Dodwell

2345 BC

2345 BC is a specific date offered by George Dodwell to identify the time for which there was consistent evidence that the tilt of the Earth’s rotational axis was altered(c). He believed that this event caused the Flood of Noah.

Coincidentally, In his 1696 book, A New Theory of the Earth [1162], William Whiston contended that an encounter with a comet, in 2346 BC, caused the

biblical Deluge, which in turn led to the destruction of Atlantis (p262 5th edition).

More recently, Reinaud de Jonge proposed(b) a similar linkage between the 2345 BC cosmic encounter and the biblical Deluge. He wrote a series of six papers on the 2345 BC catastrophe(d).

Possibly related is the year 2350 BC when“there was a ‘near-simultaneous’ collapse which saw great societies crumble and the Middle East plunged into a dark age”, according to December 2019(a) “paper published in the Monthly Notices of the Royal Astronomical Society, researcher W.M. Napier of Armagh University, Northern Ireland, wrote: ‘Studies of Earth’s history over the last 150,000 years have revealed that the climate is subject to sudden temperature changes, with transitions often taking place within decades or even a few years.”

The collapse of the Akkadian civilisation is specifically mentioned as a possible consequence of an encounter with fragments from a disintegrating Encke’s Comet hitting the Earth creating a ‘meteor hurricane’.

Mike Baillie, a leading dendrochronologist, presented to a Quantavolution Conference in Athens in 2011, compelling evidence for a catastrophic event in 2345 BC.





Whiston, William

William Whiston (1667-1752) was an English historian and theologian. In his Whiston1696 book, A New Theory of the Earth[1162],  he contended that an encounter with a comet, in 2346 BC, caused the biblical Deluge, which in turn led to the destruction of Atlantis (p.262, 5th edition). His book is now freely available online as a pdf file(a).

Immanuel Velikovsky, in his unpublished book, In the Beginning(d), has pointed out that Whiston conclusions were strongly influenced by several earlier writers, particularly mentioning Abraham Rockenbach (1536-1611).

Both George Dodwell and Mike Baillie have also offered evidence for a globally catastrophic event in 2345 BC. The ancient Chinese document, Huai-nan Tzu, recounts a legend of ten suns appearing in the sky, an account which might be related if the suggested(b) date of 2345 BC for the event could be verified.

Reinoud de Jonge offered a paper(c) linking petroglyphs found at Mougau-Bihan in Brittany with a cosmic catastrophe circa 2345 BC. He associated the event with the biblical Deluge.

He had the idea that the antediluvian population had been much greater than the present continents could accommodate and he reasoned that an additional landmass was required to cater for these extra people. Whiston took Plato’s description, of the submerged Atlantis being greater than Libya (North Africa) and Asia combined, at face value and assumed that such a large piece of extra territory would have been adequate to meet the needs of his presumed enlarged world population.





Tiwanaku (Tiahuanaco)

Tiwanaku (Tiahuanaco) is an ancient city whose remains are located over two miles above sea level near the southern end of Lake Titicaca on the Altiplano of Bolivia. It was first encountered by Spanish conquistadors in 1549. Tiwanaku has all the features of a harbour, which has led some to describe it as the seaport of nearby Puma Punku another remarkable ancient site(o).

tIWANAKUThe ruins are scattered over a number of square miles through which the Guayqui-La Paz railway was constructed, which was responsible for the breaking up of many monuments to provide ballast. Before that, stone from the site was used in the construction of nearby homes and a church.

Belisario Díaz Romero believed that Tiwanaku had been built by a race of people he calls Homo atlanticus, who had come to America from Atlantis over a landbridge from the east, outlined in his 1906 book Tiahuanacu[1235]. Heather Pringle notes(t) that before Romero, Francis de Castelnau (1810-1880), for example, proposed in the mid-19th century that Tiwanaku was the work of wandering Egyptian pharaohs, as opposed to the ‘imbecilic race that inhabits the country today’.”

The controversial Arthur Posnansky, who linked Tiahuanaco with Aztlan, the mythical “white” island homeland of the Aztecs investigated them in the early 20th century. The similarity of Aztlan with the name of Plato’s city has excited some straw clutching Atlantis seekers into claiming a definite connection between the two.

Posnansky also noted that the expected alignments of structures at Tiwanaku were offset by an amount that suggested their construction at a time when they would have been correctly aligned to the cardinal points. He, after many years of study, was convinced that Tiahuanaco was the oldest civilisation on Earth [516] dating it to around 15,000 BC. Although, as you can see below, Posnansky’s work and particularly his dating of Tiwanaku has been rejected by many, he still has supporters. In Graham Hancock‘s 1995 book Fingerprints of the Gods [275], he supported Posnansky’s date, referring to his work throughout the book. Ian Alex Blease, a devout sceptic took issue with this endorsement (aa). For my part, I note that Hancock was happy to support Posnansky in ‘Fingerprints’, but in America Before [1680], despite its title, he gives Posnansky’s date no mention, perhaps because it clashed with his new date for the destruction of his ‘Lost Civilisation’!

Charles Orser Jnr. debunked Posnansky’s dating in a 2001 article(k) as did Paul Heinrich(n). However, R. Cedric Leonard believes that Posnansky’s date addressed all of the mysteries associated with the site and “Thus I think it likely that Tiahuanaco was built at sea level c.15,000 B.C. as an Atlantean port.”(z)

Some researchers, including Jim Allen, have studied Tiwanaku’s remarkable Gate of the Sun and identified the figures carved on it as a sophisticated calendar(v).

A paper from Marco Antonio Cabero regarding the ‘Gate’ throws a modicum of doubt on its possible use as a calendar. Instead, he focused on the back side of the monument where he claims there is evidence that the ancient people of Tiwanaku knew the ‘golden number’, phi.

“The composition of the front face of the Gate of the Sun in Tiwanaku presents, anthropometric, and bilateral symmetry. On the back side, there are also harmonic proportions but with less significance. These proportions were not found before because the study of the content of its engraving frieze was believed to be a calendar, idea that has been so widely extended,that any other interpretations were ignored (however, the presence of these proportions does not exclude the possible existence of some type of calendar). The Gate of the Sun may not be part of a temple, but its content could also be considered as the expression of a monument in itself; a work that testifies the importance of knowledge, art, and science [6], [7].”(ac).

Ashley Cowie has recently proposed that Tiwanaku was located on an ancient Prime Meridian(w).

In the 1920s, Edmund Kiss studied the ruins of Tiwanaku and concluded that it had been constructed by Nordic refugees from Atlantis which had been destroyed by a falling moon! His ideas were enthusiastically received back in Nazi Germany. A further expedition was planned but never materialised because of the start of World War II.(u)

In sharp contrast, is the claim(l) by Roger Elefant that later construction at Tiwanaku was carried out by the Vikings!

However, a more recent, but catastrophic, explanation is offered by Stephen Smith(d) on the website. Perhaps Smith’s ideas might be combined with the studies of George Dodwell to produce a more comprehensive hypothesis. Posnansky’s date is greatly at variance with conventional dating that puts the flourishing of Tiwanaku at 1200 BC until 1200 AD. The latter part of that period roughly coincides with the existence of the Wari Empire, a possible rival of Tiwanaku(e).

Several claims attempting to link Tiahuanaco with Atlantis have been made, with one anonymous blog(y) insisting that it was the capital of Atlantis. James Bailey was an early advocate [149] of a Peruvian Atlantis with its capital at Tiwanaku or Chan Chan, which was probably the largest pre-Colombian city in South America.

The claim of a direct connection between Tiahuanaco and Atlantis is hard to accept on a number of grounds; for example, the idea of an army travelling from the west coast of South America to attack Greece in the east of the Mediterranean is not tenable. That there was an advanced culture in the Andes is undeniable but to link it to Plato’s story is stretching credibility to extremes. Lake Titicaca and Tiahuanaco have plenty of mysteries still to be explained. In 1980 the Bolivian scholar, Hugo Boero Rojo, aided by one of the local natives, Elias Mamani, located underwater ruins off the coast of Puerta Acosta[576]. His discoveries included megalithic temples, flights of stairs and stone roads.

Way of ViracochaMore recently, Dave Truman has written about an alignment known as ‘The Way of Viracocha’ that runs from Cajamarca in the north, through Cuzco and Tiwanaku and finishing at Pukara Grande(p), oriented exactly 45° west of true north. Truman has built on the work of Maria Sholten d’Ebneth (1926-2007), who wrote of the La Ruta de Wiracocha[1236] in the 1970s(q). Others have expanded on her work, but usually in Spanish. Truman has speculated on whether “Viracocha, the great teacher and restorer of civilisation in the Andes, in some way embodied the scientific knowledge of a sophisticated, but long-forgotten high culture?” Truman



also discusses the ‘chakana’ or Andean stepped cross and its possible meaning.

It was reported in October 2013(g) (that a team of Belgian and Bolivian archaeologists had found an assortment of ceramics, gems and gold objects at an apparent ceremonial site beneath the waters of Lake Titicaca, which was sacred for the Incas and Tiwanakus. It was not until 2019 that images of some of the artefacts recovered from the lake were widely published(x).

We cannot leave the matter of mysterious Tiahuanaco without referring to the fact that some miles further south is Lake Poopó beside which Jim Allen is convinced that the city of Atlantis was located. Allen claims that the large plain to the west of the lake is the plain mentioned by Plato as being adjacent to the city of Atlantis. In a recent documentary “Atlantis in the Andes” broadcast by ‘Discovery Civilization’, Allen identified Tiahuanaco as one of the ten kingdoms of Atlantis. However, I cannot help noticing that while Tiwanaku, claimed to be 17,000 years old, provides us with an astonishing wealth of structures and finely dressed stone, Allen’s chosen Atlantis site, Pampa Aullagas, offers little more than rubble!

Another supporter of an Andean Atlantis is Sean Bambrough, who has been developing a theory since 1999 that identifies Tiwanaku as the city of Atlantis(h).>He has now published his magnum opus on the website(ae).<

In February 2015, Marcelo Ozorio also suggested a link with Plato’s Atlantis and most interesting is the huge number of images included on his site(i). There is also a large collection of related images on a YouTube clip(m).

In 2022, Marco Vigato‘s book, Empires of Atlantis [1830] is due for publication. In it, he will be including Tiwanaku as part of the evidence for his hyperdiffusionist Atlantis(ab).

In 2008, David E. Flynn brought to public attention an astonishing series of satellite photos(a) that show a vast network of the remains apparently of man-made structures that extend for many miles around Lake Titicaca. These ‘geoglyphs’ encompass Tiahuanaco.

The most remarkable collection of early photos of the Tiwanku site can be found on the Above Top Secret website(b). The accompanying text makes a strong case for treating the location as archaeologically contaminated and as a consequence that many of the dates proposed for the site should be considered suspect. Other mysteries are the fact that saltwater Lake Titicaca contains known sea life and that old waterlines are slanted(c).

In late March 2015, the Bolivian government announced(j) that ground-penetrating radar had identified what appeared to be a buried pyramid in the Tiwanaku complex as well as other ‘anomalies’ and that excavations may start in May or June.

A mixed Spanish and English website(f) offers a number of interesting papers including a chapter from Posnansky’s book Tiahuanaco: The Cradle of American Man.

Archaeology magazine has an interesting Q & A paper relating to the history and current state of preservation at the Tiwanaku site(s).

A May 2017 report(r) confirmed that the entire Tiwanaku complex is much more extensive than previously thought, covering an area of at least 650 hectares (1,675 acres).

>Brien Foerster is an American writer who now lives in Cuzco, the former Inca capital in Peru. He has studied the ancient cultures of the Andes and believes that many predated the Incas and had advanced technologies that permitted the precise drilling of stone(af), the quality of which he has compared with examples found in Egypt and like Chris Dunn concluded that their level of accuracy could not have been achieved without possession of a high technology, now lost(ag). He has expanded on this in his 2014 book, Lost Ancient Technology of Egypt [1487].<

Pole Shift

Pole Shift is a term used to describe a range of theories that includes an alteration to or even the complete reversal of the magnetic poles, a change to the axis of rotation of the entire planet as well as a possible sudden movement of the outer crust of the Earth relative to its axis.

The magnetic poles are always on the move and well documented, while their complete reversal is a much slower process, previous reversals have left us geological ‘fingerprints’. It is suggested that another reversal is imminent, while some ‘prophets of doom’ have nominated late 2013 for the event, with dire consequences for mankind(f).

The latest data shows drift of about 40 miles a year, with a recent movement of 161 miles in just six months, creating navigation problems and the re-designation of airport runways which are named after their compass orientation(i).

Jason Colavito has unearthed an early reference to some form of axial pole shift, proposed as early 1883 in a book [1595] by the somewhat eccentric Australian, John Wood Beilby (1818-1903)(q). However, according to Colavito there was an even earlier reference to a Pole Shift by Brasseur de Bourbourg in his Historical Chronology of the Mexicans of 1873(r). He also linked this event to the destruction of Atlantis(n).

The suggestion that an ancient axial pole shift was the consequence of plate tectonics has been disputed by William Sager & Anthony Koppers of the Scripps Institution of Oceanography. Although conceding that plate tectonics may have played a part they describe the 16-21 degree change, 84 million years ago as “an odd event.”(t)

The idea of wandering (magnetic) Poles was first proposed by the German priest Damian Kreichgauer(1859-1940)(g) in 1902[513], although at the time he found little support for the concept. The late Terrence Aym was of the opinion(l) that a magnetic pole reversal was a sign that the next Ice Age was beginning! Today, NASA provides us with a more sober view of the phenomenon of magnetic pole shifts.(k).

There are a number of variations on the basic concept of an axial change and an array of suggestions for the date of the last displacement. Generally speaking the mechanism required to cause such a catastrophe is believed to be an impact by or close encounter with a large asteroid or comet. The continuing discovery of huge impact craters around the globe reinforces this possibility. However, recent studies have identified other processes that may have led to polar changes in the past(e).

The suggestion of an Antarctic location for Atlantis, as proposed by Rose and Rand Flem-Ath[062], is totally dependent on a pole shift. The Flem-Aths have interpreted the characteristics of our present icecaps as strong evidence for a number of previous pole shifts. This idea was inspired by the work of Charles Hapgood[369], who was convinced by such evidence as the Piri Reis Map and other ancient maps that seemed indicated the existence of an Ice Age civilisation now partly covered by the Antarctic icecap. Hapgood has noted[1494.71] that in the 1950’s Karl A. Pauly[1496 and George W. Bain[1498 also supported a form of crustal shift, the former building on the work of A. S. Eddington[1497 of some decades earlier.

Nevertheless, a more critical look at Hapgood’s theory reveals a number of flaws(s), which should be considered in the light of the fact that Hapgood was was a professor of history and not a geologist and Graham Hancock, who heavily endorsed Hapgood’s ideas is neither.

‘Project Atlantis’ is the title of an assignment(p) given to first-year geology students at Malaspina University-College in British Columbia. It was set by lecturer Professor Steven Earle with intention of developing the critical thinking of his students. The objective of the task is to investigate the Crustal Displacement theory of the Flem-Aths, whose ‘Atlantis in the Antarctic’ hypothesis is totally dependent on the occurrence of a pole shift resulting from some form earth crusal displacement. Kyle Bennett has written a book and a number of papers on the subject.

Pole Shift[0795] by John White, frequently associates the destruction of Atlantis with a pole shift and anticipates another one in the near future, but unfortuntely, most of the ‘evidence’ he offers in support of this contention comes from psychic sources, which cannot be accept as reliable. However, it seems that some years later White completely revised his opinions according to a 1996 report(m).

Although the majority opinion is that pole shifts occurred as a result of encounters with extraterrestrial bodies, Hapgood contended that only the outer crust of the earth shifted and that this was the result of a build-up of ice at the Poles causing instability. However, it has since been calculated that the polar ice constitutes such a small percentage of the mass of the crust that it could not possibly have caused the slippage proposed by Hapgood. This idea and others are discussed on the Pole Shift Forum(o).

Another researcher, S.F.Wells, was prompted by Flem-Ath’s work to examine the Avebury stone circle to see if there was any evidence of a pole shift there. To his surprise he did discover at Avebury and at other ancient monuments in the locality clear evidence of a pole change of up to 30° in the past. In 2003, he wrote a paper outlining his observations(c).

Flavio Barbiero has written a paper proposing that an impact with an asteroid as small as a half a kilometer in diameter could result in a rapid pole shift.

A number of facts are proposed to support the idea of a pole shift. One of the most popular is the extermination of the mammoth, which once again was central to a recent book by Charles Ginenthal, The Extinction of the Mammoth[0514], who dates the last pole shift to around 1500 BC. Perhaps the most impressive evidence came from Sweden in November 2009(b) when settlements dated to 9000 BC were discovered in the north of the country in a region that according to accepted theory should have been covered by ice at that time.

Wolter Smit points out that the orientation of some Mayan Temples is apparently out by around 17 degrees from what would be expected. A structural feature at the 4,000 year old temple of Saar in Bahrain is believed to have been used to record the summer solstice is now out by 10 degrees. Similar anomalies were noted by G.F. Dodwell during his study of ancient gnomons. A further indication that our present knowledge of polar changes may be flawed is highlighted by the fact that on April 15th 136 BC we have a record of an eclipse that completely darkened Babylon that should have had its zone of totality over the Balearic Islands in the Western Mediterranean. This is a difference of nearly 50 degrees and implies that either the Earth has slowed or the polar axis has shifted.

The idea that Pole Shift(s) can be linked to the location and orientation of many ancient sites is explored by Mark Carlotto in his new book, Before Atlantis [1600].

Amy Smith also claims that the Earth ‘tilted’ around 10,000 BC(d) referring to two ancient quotations that may support the reality of this Pole Shift – one from Plato (Tim.22d) and the other from the Book of Enoch/Noah (65.1).

The Hutton Commentaries(a) contain many articles relating to an impending pole shift based on the readings of Edgar Cayce.

In October 2004, Alexander Chechelnitsky, a Russian astrophysicist claimed that Atlantis was located in the Yukon River valley in Alaska[515]. This, he believes, was the result of a pole shift although he admits that scientific evidence is lacking for this theory!

A recent overview of the Pole Shift theory was published in July 2014(h).

Baillie, Mike

Mike Baillie is Emeritus Professor of Palaeoecology in the School of Archaeology and Palaeoecology, Queen’s University, Belfast. He is a dendrochronologist[113] of world renown, who outlined in his recent book [111] 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 Baillielegendary 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[112] 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[148](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(d) that are apparently a record of celestial demonstration(s) of plasma physics.

Nevertheless, Baillie also has his critics, particularly in relation to his attitude towards proponents of the ‘New Chronology’ such as Peter James and David Rohl(c).

Asteroids, Comets and Meteoroids are all relatively small objects that inhabit our Solar System. When any of them have orbits that intersect with that of the Earth they are known as Near Earth Objects or NEOs. Asteroids (a word coined by William Herschel [1738-1822]) used to be known as minor planets, while meteoroids is the name applied to asteroids that are less than 50 metres in diameter, although some use 10 metres as the classification threshold.

Meteorites have had a history of being considered divine in origin, leading to different levels of veneration in various cultures(v). In the 2nd century, Clement of Alexandria is said to have concluded that “the worship of such stones to have been the first, and earliest idolatry, in the world.”

What is probably the first recorded death from a meteorite strike took place in India in February 2016(z).

Comets, until recently, were generally thought to be composed of just dust and ice, ‘dirty snowballs’, which have orbits that periodically bring them close to the sun at which stage the interaction of the comet’s dust trail with the solar wind produces a highly visible coma or tail. The nucleus can have a diameter of a couple of kilometres.

The chemical composition of comets is now known to be varied and much more complex than previously believed. In 2015, Comet Lovejoy was ejecting the equivalent of “500 bottles of wine every second” when it was closest to the sun, in the form of ethyl alcohol(w). A close encounter with the Earth would have been interesting!

In 1883 a large comet is estimated to have come within a few hundred miles of Earth. It was photographed and some years later the image was hailed as the first image of a UFO!

In recent years comets have come to been seen as potentially more dangerous than asteroids in the event of a collision. This view was graphically demonstrated when the Levy-Shoemaker comet crashed spectacularly into Jupiter in 1994, after breaking up into as many as 21 large pieces before impacting. This comet was originally about 20 km in diameter. However, the distinction between comets and asteroids has been blurred by asteroids sometimes displaying the features of comets, such as asteroid P2013/P5, which in 2013 produced six cometary-like tails.

In 1752, the French astronomer, Pierre-Louis Moreau de Maupertuis, expressed the view that “However dangerous might be the shock of a comet, it might be so slight, that it would only do damage at the part of the Earth where it actually struck” and with coincidental foresight added Perhaps we should be very surprised to find that the debris of these masses that we despised were formed of gold and diamonds” considering how Richard Firestone and his associates more recently used the existence of nanodiamonds to confirm the cometary impact of 11,000 BC over North America.

Asteroids and comets have been blamed for the demise of Atlantis since the end of the 18th century. It was the Italian polymath, Giovanni Rinaldo Carli, who in 1788 declared[087] that part of a passing comet hit the Earth and was responsible for the destruction of Atlantis. A century later in his second book[022] on Atlantis, Ignatius Donnelly similarly claimed that a comet’s collision with Earth was the cause of Atlantis’ destruction(af).  Comets rather than asteroids were initially blamed because of their high visibility. However, as our technology advanced and we gradually became aware of the number of large asteroids that intersect with the Earth’s orbit they replaced comets as the more likely cause of historical impacts.

For some decades, Bob Kobres has been studying the evidence for cometary encounters contained in ancient mythologies and their possible association with known events(ah) such as the creation of the Carolina Bays or the Bronze Age Collapse(ag).

The early part of the 20th century saw the eccentric William Comyns Beaumont[088][089][090]and the mysterious Hans Schindler Bellamy[091] both supporting the idea of Atlantis being destroyed by an encounter with an extraterrestrial object. The theory has been adopted by a growing number of popular modern writers such as Otto Muck[098], Egerton Sykes, Andrew Collins[072], Paul Dunbavin[099], Karl Jürgen Hepke(a), Frank Joseph explains[102.108] how a number of scholars encouraged by Muck, came forward to publicly state their belief that Atlantis had been destroyed by an extraterrestrial impact or impacts: “They included the world’s foremost authority on Halley’s Comet, Dr M.M. Kamienski, a member of the Polish Academy of Sciences; Professor N. Bonev, one of the 20th century’s leading astronomers at the University of Sofia, in Bulgaria; and Jack Hills, of the prestigious Los Alamos National Laboratory”.

In 1971, Sykes’ Atlantis magazine devoted an entire issue to the matter of impact craters around the globe(ak).

Emilio Spedicato of the University of Bergamo has written(b) and lectured widely on his hypothesis that the last Ice Age was started by an extraterrestrial impact over a continent and ended with a similar event over an ocean. This second impact was the cause of Atlantis’ destruction and Spedicato specifies Hispaniola as containing the location of its capital.

Spedicato is not alone in believing that impacts by large objects have been responsible for the triggering of past Ice Ages. As we have seen a large number of writers have suggested an impact with the Earth as the primary or at least the secondary cause of the destruction of Atlantis(d). These cosmic collisions have occurred throughout the history of our planet, continuing to this day. Most of the impact material is small and burns up in the atmosphere. Some low-density objects have penetrated the atmosphere but disintegrated before actually impacting, generating powerful shock waves commensurate with their size. Such an event was the well known Tunguska(i) explosion over that area of Siberia in 1908.

Commenting on the Tunguska event Stephen E. Franklin added that “Less than five hours after the Tunguska object exploded at 7:14 AM local time in Siberia, another fireball was seen over Kagarlyk near Kiev in what is now Ukraine (then part of the Russian Empire) at around 7:00 AM local time followed by the impact of a 1.912 kg stony meteorite.”(ad)

>In 2001, Dr Luigi Forschini one of the leaders of an Italian expedition to the Tunguska region studied some of the 60,000 fallen trees and for the first time they also had access to previously untranslated eye-witness accounts. They concluded that the object had arrived from the southeast at about 11 km per second and that an investigation of its likely orbit concluded that it was more likely that the intruder had been an asteroid rather than a comet. They speculated that it was probably not much more than ‘a pile of rubble’ that broke up completely, leaving no crater(aq).<

The most recent (April 2020) Tunguska theory is that it could have been caused by an iron asteroid partially entering and then leaving the atmosphere!(aj) The most bizarre Tunguska suggestion is that it was the result of experiments carried out by Nikola Tesla(al). Another claim is that a massive explosion of escaping underground gas was the culprit(am). July 1st 2021 another update on Tunguska theories revealed very little that was new(ao).

Two similar explosions occurred over South America in the 1930s(ar).* However, some are large enough to survive the journey to the surface.  Depending on the size, density, speed and angle of approach, the consequences of a large impact are difficult for the average person to appreciate. As Austen Atkinson wrote[109] “A single impact by a rock the size of (London’s) Millennium Dome could devastate the surface of the globe with an explosive release of energy five times more powerful than the entire world’s nuclear arsenal. On 19 May 1996, just such an object came within 280,000 miles of Earth: six hours from collision. Humankind could have been eradicated.”

The most famous impact is probably that which is known as the Chicxulub Event in the Yucatan took place 66 million years ago and wiped out the dinosaurs. A 2017 update on Chicxulub studies was presented(ap) at the annual meeting of the American Geophysical Union in New Orleans.

A more recent (2019) paper(ae) reports that “excavations in North Dakota reveal fossils of fish and trees that were blasted with rocky, glassy fragments that fell from the sky. The deposits show evidence also of having been swamped with water – the consequence of the colossal sea surge that was generated by the impact.”

The Yucatan impact has a rival claimant in the Indian Ocean as the dinosaur killer, known as the Shiva crater. This is claimed as the largest multi-ringed impact crater in the world(an).

11 million years later another impact in the Atlantic is credited with the expansion of the mammals according to a new study by co-author, Dennis Kent from Rutgers University.

An online calculator of impact effects was developed by scientists at Purdue University and Imperial College, London was first published in 2004 and recently updated(g).

By 2009 175 large impact craters have been discovered all over our planet, many more are undiscovered having been destroyed over time by wind and water erosion or hidden by vegetation. In 2006, a crater with a diameter of 30 km was discovered in the Southern Egyptian desert. This discovery may solve a mystery in the same region that has baffled science for over seventy years, namely, the Libyan desert glass that covers an area of 60 x 100 km. However, the largest known impact crater is the Vredefort crater in South Africa with a diameter of 300 km (186 miles). But this may have to take second place to the 300-mile wide crater identified in Hudson Bay in North America.

The spectacular collision of Comet Shoemaker-Levy with Jupiter in July 1994 and how it disintegrated into a number of huge pieces before impacting over seven days, may offer one possible explanation for the mechanism that could produce the apparent clustering of 3rd millennium BC impacts on Earth.

The current estimate is that there are more than 2,000 asteroids exceeding a kilometre in size together with 10,000 over half a kilometre plus millions of smaller items in Earth-crossing orbits; collectively known as ‘Apollo objects‘. The meteor that exploded over central Russia in February 2013 belonged to this Apollo group. Add to this the risk from comets, normally larger than asteroids, and it is obvious that large-scale impacts are inevitable, however infrequent. The good news is that in 2011 it was reported that a NASA space telescope recorded a 40% reduction in their earlier calculation(j) which should be compared with the assessment referred to(f) at the end of the last paragraph of this entry. May 2012 saw further estimates being published(l).

Terminology, definitions and number estimates are constantly changing. Asteroids that are more than 100m across with orbits that come within 7.5 million km of Earth are now referred to as PHAs (Potentially Hazardous Asteroids). As of June 2014, the IAU has listed 1,466 PHAs, while NASA estimates put the actual total in excess of 4,700(q).

As recently as 1953 an asteroid impact with the Moon was photographed as a flash and only in 2002 was the resulting 2Km- wide crater identified. The estimated energy released by this 300-metre wide object on impact would have been half a Megaton of TNT (35 times the Hiroshima bomb). A hit of this magnitude on Earth could have wiped out a large city.

It must be kept in mind that the immediate damage caused by the impact itself is only the beginning of the story; tsunamis, volcanic eruptions, earthquakes together with worldwide long-term dust veils could trigger climate change leading to ongoing adverse effects on vegetation and animal life. For humans, this meant death, destruction, floods, repeated crop failures and probably a breakdown in any existing civil order.

It was as recent as the 1930’s that geologists were being told that Meteor Crater in the Arizona desert was the only known evidence that an impact, with worldwide consequences, had ever taken place. It was also in the 1930s that the first of the Apollo objects were identified. Since then, the number of large identifiable impact craters grew to hundreds and the number of Apollo objects, whose impact would have global implications, became thousands. It then became obvious that the Earth as we know it is at serious risk. World authorities are slowly realising that the probability of similar impacts in the future is simply inevitable.

Until recently, statistical analysis indicates a major impact every 10,000 years; with the last such event occurred 12,000 years ago possibly destroying Atlantis, directly or indirectly. However, in 2006, this estimate was revised downward to a major collision every 1,000 years with the last impact having taken place around 2800 BC, in the Indian Ocean, where an 18-mile diameter crater has been discovered at a depth of 12,500 feet.

However, a paper(x) published in October 2015 has suggested that a study of mass extinctions over the past 260 million years appear to have taken place every 26 million years coinciding with major asteroid/comet impacts.

So far 175 large impact craters(e) have been discovered all over our planet, many more are undiscovered having been destroyed over time by wind and water erosion or hidden by vegetation. In 2006, a crater with a diameter of 30km was discovered in the southern Egyptian desert. This discovery may solve a mystery in the same region that has baffled science for over seventy years, namely, the Libyan desert glass that covers an area of 60 x 100 km. However, the largest known impact crater is the Vredefort crater n South Africa with a diameter of 300km (186 miles). But this may have to take second place to the 300-mile wide crater identified in Hudson Bay in North America. A 2015 report tells of two impact zones that total more than 400 kilometres across, which were identified in the Warburton Basin in Central Australia(t).

Although it appears that similar suggestions have been made since the 1950s, the debate has now reached a new level. The Hudson Bay feature has generated even greater interest since Richard Firestone, a nuclear physicist together with Allen West and Simon Warwick-Smith published[110] their claim that it was created around 11,000 BC and had human witnesses who preserved their memory of it in their local folklore and that may have been responsible for the extermination of the Clovis people(ai). Firestone’s tentative 11,000 BC date for this event is earlier than Plato’s even more questionable 9600 BC date for the destruction of Atlantis might be connected since the event described by Firestone & Co. would have had global consequences and could have affected any suggested Atlantis location. In 2007, at a news conference during the Joint Assembly of the American Geophysical Union, in Acapulco, Mexico, two archaeologists from the University of Oregon, Douglas J. Kennett and Jon M. Erlandson added geological evidence to support Firestone’s thesis. In 2008 evidence of an exploding comet/asteroid over Canada during the same period was presented(c) by other academics from the University of Cincinnati. However, it must be noted that the Firestone hypothesis has encountered some criticism since the start of 2009 and must therefore be treated with due caution. This criticism appears to be gaining support according to a May 2011 report(h). In June 2012, James Kennett, son of Douglas Kennet mentioned above, was part of a team who announced further evidence of a major impact event 13,000 years ago extending from Pennsylvania and South Carolina as far as Syria(m).

Dr Reinoud de Jonge has written several articles(d) that drew on petroglyphs in Brittany to support his contention that the Earth had an encounter with a cometary body in 2345 BC. This would appear to complement the work of Mike Baillie and George Dodwell, who echoed William Whistons proposed date of 2346 BC, for an encounter with a comet that caused the biblical Deluge.

Since only 30% of our globe is exposed land, it is reasonable to conclude that 70% of impacts will have hit water, leaving little lasting evidence. However, at least ten of these identified impact craters occurred after the last Ice Age and at least seven of them date from around the third millennium BC, a period when there were widespread cultural collapses.

In a recent book[111] the renowned dendrochronologist, Mike Baillie, has outlined compelling evidence from his discipline combined with ancient mythologies to support the idea of extraterrestrial impacts in early historical times. May I suggest that the mythologies that possibly relate to multiple impacts are in fact recollections of a comet that had been visible for some time before breaking up under the gravitational influence of our planet before impact? This idea was developed by Baillie in a subsequent book[112] written with Patrick McCafferty that focused on Celtic mythological figures. Comets rather than asteroids are more likely to have contributed to the development of myths since an asteroid would not have been visible long enough for it to develop an identity that would be remembered in legend. Graham Phillips has gone further and proposed[036] that a close encounter with a comet in the middle of the 2nd millennium BC triggered the development of monotheism at that time. Furthermore, he contends that as the Earth passed through this comet’s tail, it introduced large quantities of the amino acid, vasopressin that heightened aggression in humans leading to large scale conflicts worldwide. This comet, 12P/Pons-Brooks is due for another close encounter with Earth in 2024.

A 2012 paper(o) by Fernando Coimbra investigates the influence of unusual astronomical events, in particular comets, on the subject matter of rock art. An earlier paper(p) by Coimbra looks at the swastika as a specific example of a reflection of such an event.

Mythologies, worldwide, offer evidence of these impacts and have been subsequently reinforced by classical writers who describe in non-scientific terms the effects of these extraterrestrial assaults. Pliny wrote in his Natural History (Book II, sec 91) of ‘A terrible comet was seen by the people of Ethiopia and Egypt, to which Typhon, the king of that period, gave his name; it had a fiery appearance and was twisted like a coil, and it was very grim to behold: it was not really a star so much as what might be called a ball of fire.’

Similarly, the Greek myth of Phaëton has been interpreted as a record of an encounter with a comet. Edith and Alexander Tollmann also identified an 11,000 BC impact with the Köfels region of the Austrian Tyrol as one of the impact zones. The interpretation of ancient legends and myths is a matter of subjective response, but the volume of such evidence is so great that the probability of a number of major impacts being within the memory of man, who relayed the experience down to us through the medium of tradition, is quite high.

The fact that our Earth is continually at risk of a cosmic collision, the physical evidence of recent and past collisions, the recording of impacts on the Moon and Jupiter compounded with stories in ancient mythologies offer strong grounds for accepting the possibility of Atlantis being destroyed as a result of a collision with an extraterrestrial object as a credible working hypothesis.

While an asteroid impact destroying Atlantis is relatively easy to accept, some authors have proposed even more dramatic scenarios where the impact was so great that it caused the Poles to change position and/or the Earth’s outer mantle to move relative to the inner core. There is little doubt that cosmic collisions of all the possible natural catastrophes pose the greatest possible threat to life on earth. There is an interesting website(c) that discusses both catastrophes and Atlantis. Another site(e) has a small collection of images of impact craters as seen from space. 2010 produced a frightening upward reassessment of the asteroid threat(f).

In 2001, NASA(k) identified 1,000 asteroids and comets orbiting close to Earth that are capable of causing catastrophic damage to our planet in the event of a collision. An interesting map was published(n) in February 2013 showing the locations of 34,513 impacts dating back to 2300 BC.

Recent deliberate encounters with comets and asteroids have produced images and data that have raised questions about the traditional description of comets being composed of ice and rock. The lines between asteroids and comets are becoming increasingly blurred and new definitions are required(r). The trend now is to see asteroids and comets as part of a continuum. Evidence is emerging that the H20 previously associated with comets may have been OH radicals(s).

The 2014 landing on Comet 67P/Churyumov-Gerasimenko would appear to have destroyed the ‘dirty snowball’ description of comets, coined in 1950 by the noted astronomer, Fred Whipple, and should now be abandoned.

Although large asteroids or comets have caused and will again cause global catastrophes on a scale that we can only imagine, they are not the greatest potential threat to our existence. It is estimated that our galaxy, as in others, are also home to free-floating giant gas planets untethered to any star, which, if they wandered our way, could not only obliterate our planet but de-stabilise our solar system.(u)

Terry Westerman offers a fascinating overview of possible global impact sites on his fully illustrated website(y).

Fortunately, the death and destruction caused by comets are balanced by the probability that they are also the source of life on our planet. This idea is gaining greater acceptance with a further paper(aa) offering additional supportive evidence published in April 2016.

Nevertheless, improved vigilance is required if we are to believe Peter Brown of the University of Western Ontario, whose research in 2014 concluded(ab) that hazardous asteroids are 10 times more likely to hit Earth than previously thought!
