Came across this little nugget of nonsense today: “Asteroid 2012 DA14 and escalating headlines.” The brief post, courtesy of Doubtful News, concerns how the small chance (2300:1) of asteroid 2012 DA14 hitting *one* of our satellites in geosynchronous orbit is being hyped by various news outlets. The piece concludes:
There are 401 satellites currently in geosynchronous orbit strung along a circle 265,000 kilometers in circumference. The two closest satellites are about 70 kilometers apart. There is no way it could hit two and the odds of it hitting one, even if it were to pass exactly through the ring of satellites, is about 1 out of 2300.
Yeah, sure, but you’re dismissing the Mayan prophecies, fella! What about that! I don’t hear you talking now!
Right; only because you really can’t speak comprehensibly and yawn at the same time.
Nothing new to PaleoBabble readers.
Another succinct and interesting post by Jason Colavito on that nemesis of clear thinking, the ancient astronaut theory. It’s about Soviet interest in the theory. Some Russians are just as gullible as those in the good old USA.
I’m a bit behind on posting these items, so my apologies. But I have to admit I’ve basically lost interest in it. I see nothing compelling in Charlesworth’s report, but you can read it for yourself. James Tabor naturally linked to it and has some commentary of his own. Mark Goodacre posted his thoughts here and here.
Here’s an excerpt of the summary:
Egyptian astronomers used what they learnt to make predictions about the future. They drew these up in the form of calendars showing lucky and unlucky days.
The predictions were amazingly precise. Each day was divided into three or more segments, each of which was given a rating lying somewhere in the range from very favourable to highly adverse.
One of the best preserved of these papyrus documents is called the Cairo Calendar. Although the papyrus is badly damaged in places, scholars have been able to extract a complete list of ratings for days throughout an entire year somewhere around 1200 BC.
An interesting question is how the scribes arrived at their ratings. So various groups have studied the patterns that crop up in the predictions. Today, Lauri Jetsu and buddies at the University of Helsinki in Finland reveal the results of their detailed statistical analysis of the Cairo Calendar. Their conclusion is extraordinary.
These guys arranged the data as a time series and crunched it with various statistical tools designed to reveal cycles within it. They found two significant periodicities. The first is 29.6 days–that’s almost exactly the length of a lunar month, which modern astronomers put at 29.53059 days.
The second cycle is 2.85 days and this is much harder to explain. However, Jetsu and co make a convincing argument that this corresponds to the variability of Algol, a star visible to the naked eye in the constellation of Perseus.
So, why post this on PaleoBabble? Basically, because of this post from the Daily Graal suggesting that this discovery will dredge up talk of the “mystery” of the Dogon’s knowledge of Sirius.
As readers know, I think there is zero evidence in support of ancient astronaut visitation of the Dogon, primarily because recent research has demonstrated that the theory is based on the word of one Dogon, whose story and mythology is unknown and unconfirmed by other Dogon elders (for starters).
But should I reconsider ancient astronauts in light of this discovery?
Uh … no. Did you read the excerpt above? Read it again. The Egyptians did what they did using two very human techniques: (1) naked eye astronomy (“the variability of Algol, a star visible to the naked eye in the constellation of Perseus“) and (2) a little thing we earthlings call math.
Sorry. No aliens needed for this either. But it’s pretty cool — and shows once again how much we underestimate the ancients.
Pardon my yawn just now….
Anyone out there believe this primary data will stem the tide of the nonsensical hysteria? Nope; me neither. If the heretofore known Mayan primary material (which also does not predict the end of the world) didn’t rebut the quackery, this won’t either. But I assume readers will be interested.
Harvard University and Dassault Systems has created a virtual tour of the Giza pyramids. Pretty cool – check it out!
Too bad it’s not a video game where we can shoot aliens!
I wanted to draw readers’ attention to this post by Jason Colavito. It documents the “confusion” of Hatcher-Childress on whether he believes in ancient aliens or not. Is it confusion, or opportunism?
