Joining The Dots


Joining The Dots

I have now published my new book, Joining The Dots, which offers a fresh look at the Atlantis mystery. I have addressed the critical questions of when, where and who, using Plato's own words, tempered with some critical thinking and a modicum of common sense.

Dating Techniques

Willard_Libby2Dating Techniques have improved in leaps and bounds since the 19thcentury when Charles Lyell first gave stratigraphy widespread publicity as a means of dating archaeological finds, if only relatively. In very simple terms, generally it means that as you dig, older objects will be found under younger ones. For over a century this was one of the few dating methods available to archaeologists, but unfortunately it could not offer specific dates.

Another early dating method was ‘typology’(d), defined as the classification of artefacts according to their physical characteristics.

*This approach can be traced back to the 16th century, when John Leland (1503-1552)  began classifying bricks according to size and shape(I).*

Arguably the best known uses of the method relate to Stone Age implements and later to pottery.*Relating to Atlantis studies, we find that Jürgen Spanuth applied typology to the weaponry and dress of the Sea Peoples as portrayed at Medinet Habu to support his theory that they came from Northern Europe.*

Absolute dating began with the introduction of radiometric dating methods beginning with radiocarbon dating developed by Willard Libby in 1949. Around the same time dendrochronology was being refined as a dating method with a margin of error less than that of radiometric methods which require expensive equipment and potentially have a greater risk of contamination. This was followed by thermoluminescence (1957) for dating pottery and more recently optical thermoluminescence (1994) has been developed, enabling the dating of building stone.

Dating objects between 50,000 and 100,000 years old has been difficult as most methods have questionable reliability for this period. However, in 2004 a new method, known as quartz hydration dating was developed at UC Irvine(f).

All the above methods have varying margins of error that are continually being reduced and no doubt will improve further. These enhancements together with new exciting dating methods that can be expected to emerge, will undoubtedly have a profound influence on our understanding of prehistory. Consider how improvements in DNA analysis have enabled the solving of crimes years after cases had gone ‘cold’.

More cautionary offerings(a)(c) came from the catastrophist website, thunderbolts.info., in which events involving influences outside our planet might affect the assumptions upon which some of our radiometrics are based. Since these events are not frequent occurrences we do not, as yet, have enough data to develop reliable calibration charts.

In May 2012, the journal Nature, Ewen Callaway has an article(b) which further highlights potential weaknesses that may be encountered with radiocarbon dating.

The fascinating CAIS website offers a good overview(e) of the range of sophisticated dating techniques available today. We can reasonably expect it to expand.

A July 2015 article(g) in the Proceedings of the National Academy of Sciences. has highlighted a new threat that the burning of fossil fuels has introduced into the reliability of radiocarbon dating.

“As carbon-14 decays over time the fraction will decrease so that’s how we use it for dating,” the paper’s author Dr Heather Graven told BBC News.

“But we can also change this ratio of radioactive carbon to total carbon, if we are adding non-radioactive carbon and that’s what’s happening with fossil fuels, we get this dilution effect.”

“At current rates of emissions increase”, according to the research, “a new piece of clothing in 2050 would have the same carbon date as a robe worn by William the Conqueror 1,000 years earlier.”

The latest dating method, proposed by Michael Dee and Benjamin Pope(h) combines dendrochronology with radiocarbon dating and is designed to identify specific years based on spikes in the carbon14 found in specific growth rings, caused by energy discharges during solar storms. Dee and Pope have called this new science astrochronology and anticipate that its application will tie down the so-called ‘floating chronologies’ of ancient Egypt and elsewhere.

Thera

Thera is an ancient name for today’s Aegean archipelago of Santorini, which are the remains of a volcanic island.

Only two of the islands are inhabited, the main island, Santorini and Therasia, which had been joined before the 16th century BC eruption. Recent excavations have revealed a pre-eruption settlement on Therasia(x).

Pre-eruption Thera

Pre-eruption Thera

Although it exhibited low-level activity in 1939-41 and 1950-51, it was in 1926 when it last erupted violently, destroying many hundreds of buildings in less than a minute. Eruptions of similarity intensity occurred in 1650, 1707 and 1866. It was also the site of probably the most powerful and destructive volcanic explosion in the Mediterranean during the Bronze Age. Although the exact date of this event is still the subject of some controversy the most recent evidence(a) indicates a date around 1613 BC ±13years, while archaeologists are more supportive of a date circa 1500 BC. Professor Floyd McCoy is currently planning an eighteen-month study of the matter in Greece, in the hope of resolving this dating conflict. There was clearly a series of eruptions that ended with a final enormous explosion that has been linked to the ending of Minoan civilisation on Crete, the Plagues of Egypt and agricultural failures throughout the Eastern Mediterranean. For a geologist’s view of the island’s dramatic history, Walter Friedrich’s book[428]is hard to beat. His book supports a 1640 BC date for the eruption although he has subsequently revised this to 1613 BC. Sturt W. Manning supports[957] a 1628 BC date and Mike Baillie has offered dendrochronological evidence for a 1628 BC eruption date to the 2011 Quantavolution conference in Athens(j). This converges with McCoy’s date above. However, the dating of the eruption continues to be controversial as this December 2012 link(i)demonstrates.  At the heart of the problem is that acceptance of an early 17th century BC date for the event conflicts with established Egyptian chronology. While the exact year of the eruption continues to be debated, there is now scientific evidence that it occurred in early summer(s).

A 2014 paper published in Antiquity by Paolo Cherubini would appear to confirm the 16th century BC as the date of the catastrophic eruption ruling out an earlier date as untenable(o). In the same year, the University of Birmingham published a report(u) that supported the 1625 BC date. The earlier Antiquity paper prompted a response by a group, led by Sturt Manning later in 2014(y).

*In August 2018, an interdisciplinary group led by dendrochronolist Charlotte L. Pearson published a paper(ab), which concluded that the eruption of Thera took place in the 16th century BC. This conclusion was the result of using a combination of dendrochronology along with high-resolution radiocarbon dating methods.*

October 2018 saw further evidence for an early 16th century BC date for the eruption emerge after the radiocarbon dating of some olive wood found on Therasia, one of the Santorini group(z). The same month saw the publication of a paper on the ResearchGate(aa)  website date the event to 1727-1600 BC!

The doctoral thesis of Dr. David Sewell explores the cultural effects of the Theran eruption and can be read online(h).

The volcanic ash deposited by the Theran eruption was centuries later to be used in huge quantities to manufacture cement for the construction of the Suez Canal. It was during the mining of this material that workmen encountered large stone blocks under the layers of pumice, indicating buildings of a great age.

It is claimed by many that a garbled Egyptian description of this devastating event was the basis for the story of the destruction of Atlantis. Louis Figuier was the first, in 1872, to publicly link the demise of Atlantis with the explosion on Thera. Opponents of this theory counter it by pointing out that Plato describes the inundation of an island much larger than Santorini or Crete, located in the Atlantic following an earthquake, not a volcanic eruption many thousands of years earlier. Various attempts have been made to reconcile the Minoan Theory with these apparent inconsistencies with Plato’s text. They are discussed separately under

Date of Atlantis’ Collapse

Pillars of Heracles

Size of Atlantis

It was announced at the end of February 2010 that the BBC was about to air a dramatisation of the Theran disaster as well as a documentary on the eruption as its influence on the development of Plato’s story of Atlantis. June 2010 saw the historian, Bettany Hughes, front a disappointing BBC Timewatch Special, which also promoted the idea of the eruption on Thera as the inspiration for Plato’s story of Atlantis. The material introduced as evidence was highly selective and, for me, unconvincing. A few parallels between Thera and Plato’s description were trotted out, while the more numerous differences were ignored!

Alain Moreau has written a highly critical review(v) of the idea that the island of Thera/Santorini had been home to Atlantis.

Dr. Dora Constantinidis who studied under Prof. Christos Doumas delivered a lecture in Melbourne on May 29th 2014 with the inviting title of Unravelling the Atlantis Myth at Akrotiri. However, the primary purpose of the talk was not to advance our knowledge of Atlantis but to encourage the sale of Bronze Age inspired merchandise(p).

Another twist on the Thera explosion is offered by Andis Kaulins who suggests that there is a connection Theran eruptionsbetween that event and the Biblical story of Sodom and Gomorrah(g), while Riaan Booysen has linked two separate Theran eruptions with two Exodus events in the Bible(k), offering as evidence, the existence of two distinct Theran ash fallout areas, caused by different wind directions at the time of the events.

Initially, it was thought that the collapse of the Theran caldera generated very destructive tsunamis, but new studies have concluded(w)  that instead that it was the violent entry of pyroclastic flows into the sea that triggered the tsunamis.

A further possible consequence of the Theran eruption(s)  was proposed after the discovery of the Nebra Sky Disk(n), which was buried about 3,600 years ago. This is suggested Nebra Sky Diskto have resulted from the volcanic ash generated by the eruption blotting out the sun for up to 25 years. It is thought that the Disk had been used to synchronise the lunar and solar calendars(l) and when this was no longer possible the Disk was buried as some form as offering. A contrary view is offered elsewhere on the Internet(m), as well as further controversy(t) led by Peter Schauer from the University of Regensburg.

Andis Kaulins has also written an extensive paper on the Nebra Sky Disk. A 2014 update(r) on the Disk was posted by Claudia Bracholdt.

An extensive bibliography of books and articles on the subject of Thera can be found on the Internet(b).

Theophrastus (M)

Theophrastus (372–287 BC) was a student of Aristotle, whom he eventually succeeded him at the Lyceum, the home of the Peripatetic school of philosophy. He is frequently quoted as referring to Atlantis having colonies in the ‘sea’. Philo of Alexandria in his De Aeternitate Mindi[1423] has cited Theophrastus’ belief in the reality of Atlantis. Thorwald C. Franke expands on this in Appendix F of his Aristotle and Atlantis[880].

Theophrastus is sometimes referred to as the ‘father of botany’ and was one of the earliest writers to note that trees gained an extra outer layer each year. However, it would take over two thousand years before this fact led to the development of today’s invaluable science of dendrochronology.

 

Dendrochronology

Dendrochronology is the science of dating the age of timber by comparing the sequence of its tree-dendroring width variations with that of timbers of a known date, ideally belonging to the same species and from the same location. As with any science it is not without its difficulties(c), but is generally considered to be more accurate than radiocarbon dating, which is frequently calibrated using dendrochronology. Fully anchored chronologies now exist for river oaks in parts of Germany dating back over 10,000 years and a similar chronology extending back 6500 years exists for the bristlecone pine of California’s White Mountains. A new project(b) involving the Kauri trees of New Zealand has commenced, which should give an accurate climate record for the past 30,000 years. Some of these trees are dated to 130,000 years ago.

Professor Mike Baillie, one of the leading dendrochronologists in Europe, has written[111] about ‘dendro’ evidence of cometary impacts. One such impact has been suggested by a number of commentators, as the possible cause of the demise of Atlantis.

While the science of dendrochronology is perfectly sound there can a need for fine tuning to take account of unexpected factors like the nibbling of tree trunks by animals such as sheep. Recent studies in Norway(d) over a nine year period provided data enabling appropriate calibration to be achieved.

In 2014, Gunnar Heinsohn, a German chronology revisionist, questioned the value of dendrochronology, which was followed by a rebuttal from Mike Baillie(e).*This debate continues, with many specific details far from resolved (f).*

Professor Henri D. Grissino-Mayer, of the University of Tennessee, has a most informative website(a) on dendrochronology.

Baillie, Mike (t)

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 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

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 an 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.

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 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 was the cause of Atlantis’ destruction. 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.

The early part of the 20th century saw the eccentric William Comyns Beaumont[088][089][090]and the mysterious Hans Schlindler 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”.

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 know 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) *

Two similar explosions occurred over South America in the 1930’s. 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 in the Yucatan took place 66 million years ago and wiped out the dinosaurs. 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 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 the manner in which 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 in excess of 100m across with orbits that 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 actual 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 1930’s 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 are 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 year 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 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 1950’s, 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 11000 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. Firestone’s tentative 11000 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 effected any suggested Atlantis location. In 2007, at a news conference during 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 to 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 a number of 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 which date from around the third millennium BC, at period when there were widespread cultural collapses.

In a recent book[111] the renowned dendrochronologist, Mike Baillie, has outlined compelling evidence from his own 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 prior to 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 an 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 obviously 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 causing the destruction of 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 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 is 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!

Radiocarbon Dating

Radiocarbon Dating was developed by a team led by Willard F. Libby just after World War II and won him a Nobel Prize for the work. However, in his Willard_Libby2acceptance speech Libby generously acknowledged the contribution made by the earlier work of Serge Korff (1906-1989).

Radiocarbon Dating is based on the fact that when organisms die the amount of Carbon-14 in the remains decay at a fixed rate. Although initially hailed as a definitive dating method for organic remains, it soon became obvious that it was not quite as reliable a tool as initially thought, although still widely used.

Originally a Carbon-14 half-life of 5568±30 years was used and is known as the Libby half-life. Later this was revised to 5730±40 years and is known as the Cambridge half-life. The initial theory was based on the assumption that Carbon-14 was being produced at a constant rate. However, this constancy has been questioned, as it can vary as a result of changes in the earth’s magnetic field. The intervention of man in the form of atomic bomb tests briefly doubled the amount of Carbon-14 produced(I). Local events can also have a dramatic effect on measurements; for example, the Tunguska explosion left the soil there so enriched with Carbon-14 that it gives a date in the future (1)! Emilio Spedicato has also pointed out that Carbon-14 can be created in the atmosphere by any cometary or asteroidal impact and so alter the assumed constant ratio of C12 to C14.

Immanuel Velikovsky offered the following valuable observation(j) as the method was refined, it started to show rather regular anomalies. First, it was noticed that, when radiocarbon dated, wood grown in the 20th century appears more ancient than wood grown in the 19th century. Suess explained the phenomenon by the fact that the increased industrial use of fossil carbon in coal and in oil changed the ratio between the dead carbon C12 and the C14 (radiocarbon) in the atmosphere and therefore also in the biosphere. In centuries to come a body of a man or animal who lived and died in the 20th century would appear paradoxically of greater age since death than the body of a man or animal of the 19th century, and if the process of industrial use of fossil, therefore dead, carbon continues to increase, as it is expected will be the case, the paradox will continue into the forthcoming centuries.”

Graham Phillips mentions[0034] that ‘recent evidence suggests that that the level of Carbon 14 in the atmosphere may have decreased permanently around 3,500 years ago due to changes in the earth’s magnetic field.’ This has resulted in dates around that period being up to 500 year out. Calibration figures are now available to take account of some of these deviations based on data from dendrochronology, ice and sediment cores and coral samples. Further refinements are not to be ruled out.

These weaknesses in radiocarbon dating have been seized upon by some fundamentalist Christian groups determined to justify their ‘young earth’ beliefs(d). However, attacks on the basic concepts underlying radiocarbon dating have been refuted by its supporters(e).

In 774/5 AD an increase of 1.2% of Carbon14 was detected through tree ring studies(c). This is thought to be the result of an external event such as a supernova or solar flare. Since many other episodes of a lesser or greater intensity have probably occurred, a growing shadow is being cast over the reliability of radiocarbon dating that may only be dissipated by further studies. Clearly, further complex recalibration is not to be ruled out, as it is highly unlikely that this eight century event was the only such occurrence.

A recent report(h) has drawn attention to the danger of using fossil fuels, as it pumps a type of carbon into the atmosphere that confuses the dating technique. Scientists say that by 2050, new clothes could have the same radiocarbon date as items 1,000 years old!

Radiocarbon dating is only useful up to a maximum of around 50,000 years. In February 2010, researchers at Queens University Belfast announced a new calibration curve that extends back over the 50 millennia. The production of this calibration curve is the result of 30 years research into the variations in atmospheric Carbon 14 caused by solar activity, the earth’s magnetic field and the oceans. Other radiometric dating methods are now available to deal with dates beyond this limit.

2010 also saw another important refinement of radiocarbon dating with the development of a ‘non-destructive carbon dating’ method which will enable the dating of very delicate, rare or highly valuable artefacts, without having to destroy any samples from them, as is required at present(a).

One strong dissenting voice was that of archaeologist, Zahi Hawass, former Secretary General of the Egyptian Supreme Council of Antiquities who said “Carbon-14 dating has a margin of error of 100 years. In order to date Egyptian dynasties, we need to have specific dates; you cannot use carbon dating,” Hawass explained further to Al-Masry Al-Youm. “This technique shouldn’t be used at all in making changes to the chronology of the ancient Egypt, not even as a helpful addition.”(b). Incidentally, in April 2015, Hawass walked out of a debate with Graham Hancock over the inclusion of an image of Robert Bauval in Hancock’s presentation(g).

Emmet Sweeney tells a disturbing story of how some establishments have treated inconvenient C14 results, recounting[700.221] “the fate of samples from the tomb of Tutankhamun subjected by the British Museum to radiocarbon testing. The samples, consisting of fibers of a reed mat and a palm kernel, produced dates of 844BC and 899BC respectively. These were broadly in line with the date for Tutankhamun predicted by Velikovsky, but roughly 500 years too recent for textbook chronology. In spite of assurances given to Velikovsky that the results would be published, they never saw the light of day.” [758.xvi]

In Forgotten Civilization[867] and his earlier Pyramid Quest[456], Robert Schoch has drawn attention to a number of difficulties that have arisen with radiocarbon dating and the implications for Egyptology. A warning about future difficulties with the reliability of radiocarbon dating has been issued by Heather Graven, a climate-physics researcher at Imperial College London. She has found that the rate of fossil-fuel emissions is skewing the carbon ratios used to determine an object’s age. She estimates that by 2050 atmospheric carbon dioxide will make new organic material appear to be 1,000 years old(2). Graham Hancock has also expressed reservations regarding the use of radiocarbon dating, urging both caution and open-mindedness(m).

An even more jaundiced view of current dating difficulties is expressed(l) by Jonathan Gray.

One of these, namely, the potassium/argon method has been claimed by writers such as Richard Milton[521] to have its own inherent problems and must be treated with caution. It appears that although dating methods have advanced greatly further improvements can be expected.

The latest refinement of radiocarbon dating techniques has shortened the time taken from six days to two and additionally, now allows on-site testing(f).

The Malagabay website(n) posted a series of blogs through April 2017 under the heading of ‘Deranged Dating’ highlighting weaknesses in radiocarbon dating!

There is now a valuable list of papers(o), with links, devoted to the many problems that have gradually emerged in relation to radiocarbon dating. This just part of the ‘A New Chronology’ website(p).

*June 2018 saw a report issued from Cornell University that highlighted some inaccuracies that have been found in dates relating to the southern Levant region, which includes parts of Jordan, Israel and Egypt.Archaeologist Sturt Manning and his colleagues “have revealed variations in the radiocarbon cycle at certain periods of time, affecting frequently cited standards used in archaeological and historical research.” (q)

Currently, standard calibration curves assume that at any given time radiocarbon levels are similar and stable everywhere across each hemisphere. It seems therefore that the calibration of radiocarbon dates will have to take regional factors into consideration in future.*
