"Hyperbolic Tetrahedral Geometry"
Take a tetrahedron (4-sided solid made of four equilateral triangles) and put it in a sphere such that each point of the pyramid touches the inside surface of the sphere. Draw a straight line through the center of the sphere such that one end of the line intersects a point of the pyramid; think of this line as the polar axis, and now orient it in your mind so that the line that goes through the pyramid point is down. Now draw a line around the circle’s equator. Now, if you take the angle between the equator, the center of the sphere, and one of the three non-pole points of the pyramid, you get 19.5°.
That’s the magic of Richard C. Hoagland’s hyperbolic geometry and all the claims of importance for the 19.5° latitude that I’m going to explore in this post.
Richard C. Hoagland’s Magical Thinking
Richard C. Hoagland says a lot of stuff. Almost everything he says sounds crazy. Over the decades, he has built up a vast conspiracy-laden mythology about the universe, how it supposedly works, and why things are the way they are.
To go into every single one of his claims, as I’ve said before in other posts about Hoagland (like here, here, or here), would be next to impossible. As in previous posts, the point in this is to go over a very specific claim.
The “19.5° is an important number” stems from his whole “hyperdimensional physics” mythos. Again, something I’m not going to go into. Partly because it’s incomprehensible, nonsensical, and made up. Suffice to say, “A tenet of these views holds that vast amounts of energy originating from dimensions we cannot perceive are available at latitudes 19.5° both south and north on the Sun and every planet in the solar system” (quote source).
In other words, Hoagland and fellow believers claim that it is at 19.5° latitude on every body in the solar system that we have the biggest/bestest/scarriest/craziest/powerfulest/whateverest feature. Let’s take a look, shall we?
What’s at 19.5° Latitude?
Taken from Hoagland’s own website, we have a short list proving that everything of importance in the solar system is at 19.5° latitude. Note that everything in this table is directly copied from his website except for the comments, which I have simplified/shortened/clarified.
||A Volcanic Region
||A Volcanic Region
||Largest Shield Volcano (on Earth)
||Unique Farside “mare-like” Lava
||Largest Shield Volcano (on Mars)
||Great Red Spot
||Vast Atmospheric “Vorticular Upwelling”
||North/South Equatorial Belts
||Region of “Storms” Observed from Earth
||Northern/Southern IR 1-2 K “Dip”
||“Upwelling” Created by High-Altitude Clouds
||Great Dark Spot
||Presumably Same as Jovian Counterpart*
*Hoagland calls this “Neptune Great Red Spot” but it has, since it was observed by Voyager 2 in 1989, disappeared.
Since Hoagland posted this (his page is ©1989), many other people have found other things on other planets that they claim enhances this idea. One such site, for example, indicates that the Pyramid of the Sun is at 19.6° N (on Earth). Other people claim, such as Will Hart, that all solar storms and susnspots originate from 19.5° latitude on the sun; another twist from this site about the sun is “sunspot activity and the region of peak temperatures is limited to 19.5 degreees north and south.” Others remark simply, “It is interesting how most planets in our solar system display phenomena at this latitude.” The list of claims goes on.
Dissecting the List, and Are These Features Important?
One of the first things you should notice from Hoagland’s list is that only one of the 9 things I pulled (the ones I didn’t are on Jupiter’s moon Io) is at 19.5°. Two more are within 0.1° of it. For a precise geometric phenomenon where huge amounts of energy are released, this isn’t very precise.
On Earth, Mauna Loa, Hawai’i, with a summit at 19.48° is a correct claim of the largest shield volcano presently on the planet. However, it’s really not that spectacular a volcano in terms of energetic potential. The Yellowstone caldera is about 34×45 miles (55×72 km) across. That’s just the caldera. It is at a latitude 44.4° N. The most recent known supervolcano eruption on Earth was in Lake Taupo, about 26,500 years ago, and its latitude is 38.82° S.
Additionally, the largest earthquakes – more releases of energy – since 1900 haven’t been anywhere near 19.5°. None of them.
As for structures on the Earth to harness this energy, one might consider the Pyramid of the Sun and say, “wow, that’s pretty neat that it’s at 19.5°.” But what about Egypt’s pyramids? Or South America’s? What about other architecture, say, Stonehenge? None of these are near 19.5°. This is what we call “cherry picking” to an extreme.
If we want to expand the notion of cherry picking, let’s go to the moon. Hoagland has found some random feature at 19.5° … err, 19.6° … latitude on the far side that has something to do with a volcanic feature. Except that the moon is covered in volcanic features. When you look at the moon, all those dark splotches on the near side are vast volcanic areas where ancient impacts allowed magma from deep below the crust to breach the surface and fill them. And these seas of volcanic material — maria (plural) — are not in any way centered around 19.5°. Nor are the smaller volcanic features that we observe today still strewn throughout them.
Or there’s Mars. Hoagland and his ilk claim that the vast Olympus Mons volcano – the tallest volcano in the solar system – is centered at 19.3° on Mars and is perfect evidence for this hyperbolic geometry. Except that it’s not. The caldera complex of Olympus Mons (there are at least 6 distinct calderas at the summit) range between latitudes 17.8° and 18.8° North. In addition to that, Olympus Mons is so vast with a diameter of around 650 km that the northern scarps start at around 23.5° N while the southern margin is around 13.5° N latitude. So with it spanning over 10°, it’s not that hard to hit it. Besides, Mars has 23 other major volcanoes, and Alba Patera, which is actually the most voluminous volcano in the solar system (as Mauna Loa is the most voluminous volcano on Earth), has a caldera centered at 40.3° N.
The claim of the sun having sunspots centered at 19.5° is also wrong, as can be seen on any given day.
We can also look at other features of interest. I’ll name only one for brevity since I think I’ve made my point by now. Saturn’s moon Enceladus was, in the last few years, shown to have active geysers spewing material from the interior of the moon. What’s their latitude? About 90° S — that’s right, the south pole. Not anywhere near 19.5° North nor South latitude.
This particular magical belief is only supported by very very careful cherry-picking. As clearly shown above, even in the features that these people claim shows 19.5° is special, more than half the time they’re just wrong, off the mark, or are being very generous with reporting their numbers. And still the features that are “correct” are not especially unique.
I don’t really think much else needs to be said on this topic. It’s just made up and features are found to fit it while ignoring everything else.
