My presentation at Cosmic Summit 2023

In this presentation I describe some of the supporting evidence for the astronomical interpretation of Gobekli Tepe.

Many other presentations at Cosmic Summit 2023 are also available on YouTube, courtesy of George Howard who organised the whole thing. Here's the playlist.

Debunking YouTube's archaeoastronomy skeptics

                                    Image from Scijinks.gov Some YouTube commentators, like Milo Rossi of MiniMinuteman and Stefan Milo, have made ignorant comments about the astronomical interpretation of Gobekli Tepe and Pillar 43. Below, I make the scientific case for this interpretation. Q: What is science? A: Science attempts to create consistent models of reality. Q: What is a good model? A: One that has a lot of explaining power relative to its inputs. This is also known as Occam's razor, parsimony, and model efficiency. Q: How do we measure the 'explaining power'? A: There are many ways, but the best is to use statistical methods, including hypothesis testing. Examples of statistics in science Suppose 100 pills given to a random sample of people, of which 50 are placebos. Suppose all those taking the pill are dead by the next day, but none of those taking the placebo are dead. Conclusion: the pill is deadly. The hypothesis “The pill is deadly” is made a posteriori

Holliday et al.'s (2023) Gish Gallop: timing of the Younger-Dryas onset and Greenland platinum spike

The location of several Greenland ice cores, from Steffensen et al. (2008). Over the next few months/year I'll post a regular series of blog posts that deconstruct Holliday et al.'s (2023) (henceforth, just Holliday et al.) "comprehensive refutation" of the YDIH. Some common themes will become apparent. Essentially, there are no refutation arguments at all in it, so their title is misleading. Remember, the meaning of 'refute' is to 'disprove', but there are no arguments in Holliday et al. that disprove the YDIH. It's also worth looking up the  'Gish gallop' fallacy, because that is what is happening here. Holliday et al.'s paper might be extremely long, but it is lacking in serious arguments, and there are certainly no refutations. First up in this blog post is the timing of the YD climate change (specifically its onset) and the Greenland platinum spike. The relevant sections of Holliday et al. are 3.3 and 5.1. My comments are in itali

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
