#NewHorizons #PlutoFlyby — The Pseudoscience Flows, Part 3


Introduction

I honestly haven’t seen this one that I remember — yet (I’m working on very little sleep and 14+ hour days right now) — but I suspect it’s only a matter of time from more conservative religious conspiracists: The naming scheme for Pluto and Charon. Some background is needed …

Names

In planetary science, one might wonder why we care about naming things. It seems to be a remarkably human-centric thing, for why should we have to feel like we need to stick a name on everything?

The answer is ease of communication. If you say “Tycho crater” to just about any planetary scientist, they know the exact lunar crater you’re talking about. Same with “Copernicus crater,” or “Mare Imbrium.” The alternative is something like, “The big crater with bright rays near the bottom of the moon if the north is up.” Or something like that.

Other than historic objects, things these days on planetary surfaces generally only get named if there’s a reason for it: As in, it’s an interesting feature that we’re going to be talking about a lot. Not every feature on every body is named.

International Astronomical Union (IAU) Policy for Pluto System

Because Pluto is the Roman god of the underworld, and Charon is the Greek ferryman of the dead to the underworld, the International Astronomical Union — the only official naming body in the world for naming stuff in the solar system and beyond — decided that the theme of “underworld” is going to stick, at least for major features. Sometimes this varies, but more on that later.

There is a sizable component of conservative Christians who think that any naming, or any reference, to such is an affront to their god, that it is occultism, Satan worship, etc.

Another side-rule is that no name should be duplicated.

Process

There are lots of “levels” of names. There’s the official IAU name. There are provisional, recommended names to the IAU. There are “for fun” names used within the science team. And there are “would be nice” names used by individual people.

As an example of the last item, there are many craters right now on Pluto and Charon named “Robbins” with a lot of numbers after it. For a friend, there are two “Banks” craters (one because I’m not sure if it’s real because of JPG compression artifacts). But that’s just for fun.

The more formal process, those other three levels I mentioned at the beginning of this section, varies somewhat. In the case with New Horizons and the Pluto-Charon system, a public website was launched months ago where people could both recommend and vote on names.

This was vetted by a very small group within the New Horizons science team, raking names by popularity, looking for gender and ethic biases, removing incredibly offensive names, and removing those used elsewhere (e.g., there’s a “Lonely Mountain” on Titan, so even though we’ve been referring to one on Pluto lately in the team, it cannot be recommended as an official name to the IAU, but this falls into the third category of “for fun” by the team).

So, the biggest stuff is going to get the most popular names from the list. And by “get,” I’m talking about that that second level, the recommended-to-the-IAU level. Which I think pre-approved “Tombaugh Reggio” before-hand. But beyond that, all names must be submitted to the IAU, and hence they are called “provisional names” until the IAU approves or rejects them.

The “Offending” Name(s)

Right off the bat, I figure that there will be some groups that are offended already by the “underworld” theme. But I read some very über-right-wing Christian / conservative websites. One of the beliefs among them is that anything “new age,” anything they perceive as pagan or “occult,” is Satanic, and therefore directly opposed to their version of a deity.

Enter Cthulhu (pronounced something like “coo-THOO-loo”). It was a deity created by H.P. Lovecraft. To quote from Wikipedia: “Lovecraft depicts Cthulhu as a gigantic entity worshiped by cultists. Cthulhu’s anatomy is described as part octopus, part man, and part dragon.”

Lovecraft himself is often viewed by these über-conservative Christians as an occultist/cultist himself, and the fact that a major low-reflectivity feature on Pluto that has been provisionally named after a “demonic” deity that Lovecraft dreamed up is likely going to not sit well with them.

However, my understanding is that it was selected because it was one of the most popular names in the voting.

Final Thoughts

Well, that’s it for now. Back to work. I expect to do at least two more of these, another about young-Earth creationists’ take on this and another about Crrow777’s take on this (he’s been getting a lot more press lately, so even though I really don’t want to give him more because question his mental fidelity).

Podcast Episode 84: David Sereda’s Claims Clip Show, Part 2


David Sereda:
UFOs, quantum, new-age …
Let’s see what’s out there.

Whew. This one took a long time to put together and get through. Eleven clips from Coast to Coast with David Sereda making various claims and me explaining what parts of physics, astronomy, and general astronomy are incorrect.

The purpose of this episode is to move on from the background I gave in Part 1 to a very clip-y show with lots of different claims to explore. It’s an interesting episode, I think. Not only for style, but for content. Let me know what you think.

David Sereda:
UFOs, quantum, new-age …
Let’s see what’s out there.

After realizing I had around 10 minutes of clips, lots already written, and more I wanted to write, this is a Part 1 of 2 mini-series on the claims of David Sereda.

The purpose of this episode is to provide a background into how Sereda went from a UFOlogist to a more generic new-ager with a few specific claims of his own. I then go into two of his main claims (of MANY that I’ll go more into next time) and wrap up with when giving your professional background becomes an argument from authority logical fallacy. Actually, almost everything that Sereda says is a Name that Logical Fallacy exercise.

This episode “required” me listening to approximately 40 hours of Coast to Coast AM. I took nearly 10,000 words of notes. I think I may take up drinking …

Again the new blog is WND Watch.

World Famous Astrologer Terry Nazon Redux: Word Salad of Wrongly Used Astronomy Terms with New Age Thrown In


Introduction

It’s been a long time since I wrote about “Terry Nazon World Famous Celebrity Astrologer.” I was bored last night when I should have been either weight lifting or going to bed, and I happened across her blog. I was scrolling through to see if there was any “real” astronomy in there and came across her, “Venus Retrograde The Anatomy of a Retrograde” post from May 15, 2012.

Wow.

First, Grammar

In the past when I’ve written about Ms. Nazon, I’ve made minor points about her grammar. It’s atrocious. Seriously. Anyone who is a professional (as Ms. Nazon seems to be considering that she now charges $400 to talk with her per hour) should have better grammar than she.

Throughout this post, I’m going to pick apart her three-paragraph “Venus Retrograde…” post. I’m going to be quoting verbatim a lot. Please keep in mind that these are copy-pastes and I’m not trying to make her look more ridiculous than she already is by altering her words.

What Is Retrograde Motion?

Literally, the term “retrograde” means “to go against” or “to go backwards.” Throughout the day, objects in the sky appear to move from East to West. Throughout the year, the stars seem to move just a bit faster than the sun. This means that, relative to the stars, the sun appears to travel from West to East over the course of many days.

When planets also appear to move from West to East relative to the stars over many nights, they are traveling with the sun, and so are going “prograde.” When planets move from East to West relative to the stars over many nights, they are moving “retrograde” because it’s against the motion of the sun over many days/nights.

The why of why planets will go from prograde to retrograde and back again after many months is a story that took thousands of years to figure out and was one of the main lines of evidence for heliocentrism and against geocentrism.

I really don’t want to go too much into the “why this happens” part here as I think this is going to be a long post; instead, I’ll refer you to this short animation that I made that shows a line of observation from Earth, through Mars, projected onto the stars, and the path it draws. If you look at that, then keep in mind as a basic explanation, “It’s because we ‘catch up and pass’ a planet in its orbit,” it should make some sense.

Paragraph The First

“As your horoscope week begins the planet of Love, romance, and wealth, Venus goes retrograde until June 27th. Venus typically retrogrades every about every year or 18 months, depending on its transit.”

The first sentence is surprisingly correct with regards to when Venus returns to prograde motion. The second is generally correct with how often it switches, and I’m assuming that her term “transit” is an astrology term; it doesn’t mean anything astronomically considering that the next Venus transit across the sun isn’t until 2117.

“Everyone who studies astrology tries to understand the movements of the planets and pierce understand their transits through the signs. How we see them from our perspective here on planet Earth, is sometimes quite different from what is actually happening, our perspective is skewed here on earth.”

This is Nazon’s way of setting up for why retrogrades are important, and apparently that importance helps us to “pierce understand” them.

“Retrogrades are special times when the planets appear to us from our vantage point of Earth to be moving backwards. They aren’t really. Mercury will not be transiting backwards, nor will any of the other planets. They will only appear to be moving backwards due to its position in orbit and it’s relation to the Earth …”

So far, we’re still generally okay, though the English language has suffered a bit.

“… as it moves away from the planet Earth in its orbit.”

I thought at this point that she was sort of correct, and I was going to give her the benefit of the doubt. That was until I saw the next three sentences:

“The farther an object is from us the slower it appears to be moving, it’s that simple. An object really far away appears to be moving backwards. Space and time affect our perception.”

Alright, this first sentence is true IF the object is moving at the same speed. Otherwise, all bets are off. An airplane 5 miles above me is going to move faster than the bird 20 feet above me.

The second sentence makes absolutely no sense. No sense whatsoever. It seems as though she’s extrapolating a linear relationship that stuff moves far away so it moves slower, so if it moves really far it will eventually slow down and move backwards? Um, huh!?

Paragraph The Second

“Science has proven that there is a difference in the influence of a planet when moving toward the Earth (or direct) and moving away from the Earth or retrograde.”

No. First off, “science” has never shown any influence whatsoever (astrology-wise) of other planets on Earth regardless of their position or movement in space. Since “science” has not done so, it also cannot show a difference between nothing and nothing for how that planet may be moving.

“This difference is called Red Shift.”

Cue George Takei: “Oh my.”

Ms. Nazon is confusing apparent motion across (as in “back-and-forth”) our sky with a real physical motion towards or away from us, which is red shift and blue shift. Read the link if you don’t know what these are, but suffice to say for the purposes of this post, these are nothing alike. They have nothing to do with each other whatsoever. What she basically said is, “The difference between a flute and a piccolo is tomato bisque.”

“When a planet is receding, or moving away it appears to be retrograde, the color of the light it gives off changes. It does in fact have a different measurable speed and different light spectrum. This is called Red Shift.”

As my animation example shows, Mars was moving prograde until its closest approach with Earth, at which point Earth “passed” it and Mars’ motion became retrograde. Earth was moving away from it for awhile and it was retrograde, and Earth continued to move away and it flipped to prograde. Not possible under Ms. Nazon’s misunderstanding.

I interpret these three sentences as Ms. Nazon’s misunderstanding of what’s going on and using the general astronomy terms in a “word salad,” going into overdrive. Now, she is technically correct when she says that there would be a measurable redshift as the relative velocities between Earth and another planet increase. That difference is minuscule, however, and you get a bigger difference in redshift/blueshift light from opposite limbs of the sun (since the sun rotates, the limb coming towards us is slightly blueshifted, the limb going away is slightly redshifted).

“When a planet is retrograde its influence is subnormal. Retrogrades makes the normal influence of any planet weak.”

This is just astrology-speak mumbo jumbo. I have no other comment.

Paragraph The Third

“Venus retrograde produces red spectrum lines and its influence is the antithesis or the exact opposite of Venus direct, its influence is more like Mars. Normally Venus produces a violet light. When retrograde a red spectrum light like Mars.”

As I already explained above, apparent motion back-and-forth through the sky has nothing to do with its physical motion towards or away from us. Nothing. Zip. Zilch. Nada. גאָרנישט. 何も. 没什么. Inget. (Yay Google Translate!)

That said, every object in the solar system radiates every color of light, by definition of how radiation works. Planets radiate more in the infrared because they’re cooler than the sun. Planets also reflect light, and a lot of that is in the visible. Venus’ cloud layers are mostly made of carbon dioxide (CO2).

Being a molecule, carbon dioxide has a complicated emission/absorption spectrum, but it is heavy in the infrared (which is why it’s a greenhouse gas). What makes Venus appear yellow-whitish-orange is a sulfuric acid haze in the atmosphere. If Venus’ relative motion towards/away to/from Earth really caused it to have a significant red/blue shift, then everyone would notice this. ‘Cause, well, it would appear visibly redder or bluer. It doesn’t.

I’m really amazed at how some very basic observations that “everybody” knows or can make somehow manage to get by a “World Famous Celebrity Astrologer” such as Ms. Nazon who charges $100 to talk with her for 15 minutes.

“The give and take of Venus is undermined now and many will feel they have to do more or give more to receive love, recognition, or attention. Nothing comes easy under Venus retrograde and the concept of “what’s in it for me” is always prevalent.”

And we end with more astrology stuff.

Final Thoughts

I almost didn’t do a blog post about this, then I changed my mind. I haven’t ever really addressed the “word salad” idea with regards to pseudoscience claims on this blog, except perhaps with quantum mechanics.

Ms. Nazon’s blog (and other writings) is a good example of this idea: Take some science-sounding words, add a heaping spoonful of new age, whisk vigorously until foamy, and then pour on baking sheet. Bake at 250°F for 15 minutes until half-done, then chop up and post your half-baked ideas online.
