New paper published: Rejection of Holliday et al.'s Alleged Refutation of the Younger Dryas Impact Hypothesis

Another paper that rejects Holliday et al.'s (2023; HEA) Gish gallop has been accepted for publication in Earth Science Reviews, the journal that published HEA.

Because of the word limit imposed by ESR on our rebuttal, we could publish only a summary paper that points out only the major errors in each section of Holliday et al. (2023). We sought other journals but the editors refused our request to publish our response in their journals, stating that ESR is the appropriate vehicle. Given this limitation, we had little option but to publish a summary in ESR with the extended details in Airbursts and Cratering Impacts (see the previous blog post). So the longer paper in ACI should be seen as an extension of the summary paper in ESR.

Note that, originally, ESR limited our response to 3000 words, which is clearly inadequate when rebutting an article of over 96,000 words! After appeal, ESR relented by allowing a word length limit of 6000 words. Ultimately, we were allowed to publish a 'summary' of 8000 words. Our detailed response in ACI is over 40000 words.

Rejection of Holliday et al.'s Alleged Refutation of the Younger Dryas Impact Hypothesis

Martin B. Sweatman, James L. Powell, Allen West.


Abstract

We reject the claim of Holliday et al. (2023; hereafter HEA) that they have “comprehensively refuted” the Younger Dryas impact hypothesis (YDIH). Scores of peer-reviewed articles in dozens of peer-reviewed journals from hundreds of researchers, many of whom were not members of the core research team of Firestone et al. (2007), have corroborated the YDIH and replicated the key evidence dozens of times (Powell, 2022; Sweatman, 2021). Refuting a hypothesis that is so well established should require compelling new evidence and a plausible alternative process. HEA offer neither but, instead, question the peer-reviewed evidence supporting the hypothesis. Many of their arguments are faulty and were already rebutted in earlier reviews. The remaining differences in interpretation are part and parcel of science and do not lend themselves to the refutation—that is, the falsification—of an active hypothesis. Words alone cannot do that, not even the 96,000 words of HEA. Only evidence can.

Gobekli Tepe's Pillars

Image
Significance: Gobekli Tepe (GT) probably represents the origin of civilisation for most of the world today. Most of us are connected to it in some way, through language and religion (proto-Nostratic), or genetics at least. The Pillars: GT is famous for its anomalous megalithic pillars, and especially the symbols carved on them. Most people think these symbols are telling an important story - they are not just random pictures of animals. Klauss Schmidt, who discovered GT and led its excavation, until his death in 2014, certainly thought so. It follows that the only way we will ever be able to properly understand Gobekli Tepe, and therefore the origin of civilisation, is through reading its pillars. Deutsche Archaeological Institute : the DAI operates the Gobekli Tepe dig. Despite the immense significance of the site, they continue to have a casual disregard for the information encoded on its pillars. Over 60 pillars have been uncovered, but only around 20 are documented by the DAI. Alt

The meaning of H-symbols at Gobekli Tepe (updated 7th June)

Image
The H and I-symbols at Gobekli Tepe are some of the hardest to decipher, and their precise meaning remains obscure. But there are some good clues, which allow a preliminary interpretation. Let's have a look at all the instances where H and I-symbols occur. Pillar 33: A pair of H-symbols bracket some snakes (meteors) on the inner face. The upper H-symbol is quite faint. An I-symbol appears at ground level below the snake heads, but it is hardly visible here. Also, there are more I-symbols on the side with the tall bending birds. Of course, Pillar 43 has H and I-symbols near the bird with fish/snake. But Pillar 18 has the most H and I-symbols. First, at the top, forming a kind of necklace, together with likely sun and moon symbols. Then on the belt of Pillar 18 surrounded by loops... And then also on the belt buckle surrounding what might be the head of a comet. Pillar 30 has a single H-symbol, ... while Pillar 28 has an H-symbol over another loop, with an I-symbol at the bottom.

Decoding Pictish symbols This work is now peer-reviewed and published here . Image from Aberdeenshire.gov.uk/leisure-sport-and-culture/archaeology/sites-to-visit/pictish-symbol-stones/ The Picts lived in Scotland in the 1st millennium AD, and probably before. It is generally thought that the Romans named them after the paint they wore, and they built Hadrian's Wall to protect their lands to the south from them. The Picts are famous for their symbols, which they carved into megalithic pillars. To date, these symbols have remained a mystery, although several people have provided potential interpretations. One of the most well-known is due to Jackson who interpreted them as family crests - he describes his theory in detail in his 1984 book 'The Symbol Stones of Scotland'. In my view, they are instead practically the same system of zodiacal and astronomical symbols we have found across Europe and the Near East, from Palaeolithic caves to Gobekli Tepe, Ca
