Podcast Episode 166: Stellar Evolution, Age of the Universe, and Young-Earth Creationism


Star evolution,
Age of the universe, and
Creationism.

Young-Earth Creationism strikes again and this time misuses error bars to argue that GodDidIt. The episode covers a science paper that discussed the age of a very old star which was derived to be a bit older than the universe. But, add in the appropriate error bars, and potentially a correction to its color, and there’s absolutely no issue whatsoever. But, try telling that to a creationist with an agenda. There’s only a very brief singular additional segment in this episode.

M15 from HST

The dazzling stars in Messier 15 look fresh and new in this image from the NASA/Hubble Space Telescope, but they are actually all roughly 13 billion years old, making them some of the most ancient objects in the Universe. Unlike another recent Hubble Picture of the Week, which featured the unusually sparse cluster Palomar 1, Messier 15 is rich and bright despite its age. Messier 15 is a globular cluster — a spherical conglomeration of old stars that formed together from the same cloud of gas, found in the outer reaches of the Milky Way in a region known as the halo and orbiting the Galactic Centre. This globular lies about 35 000 light-years from the Earth, in the constellation of Pegasus (The Flying Horse). Messier 15 is one of the densest globulars known, with the vast majority of the cluster’s mass concentrated in the core. Astronomers think that particularly dense globulars, like this one, underwent a process called core collapse, in which gravitational interactions between stars led to many members of the cluster migrating towards the centre. Messier 15 is also the first globular cluster known to harbour a planetary nebula, and it is still one of only four globulars known to do so. The planetary nebula, called Pease 1, can be seen in this image as a small blue blob to the lower left of the globular’s core. This picture was put together from images taken with the Wide Field Channel of Hubble’s Advanced Camera for Surveys. Images through yellow/orange (F606W, coloured blue) and near-infrared (F814W, coloured red) filters were combined. The total exposure times were 535 s and 615 s respectively and the field of view is 3.4 arcminutes across.

Podcast Episode 162: Geocentrism, Take 2


Geocentrism
Is so wrong, even young-Earth
Creationists know!

Slightly longer segment this time, a bit of a mishmash between episodes 78 and 152, young-Earth creationists refuting geocentrism. I go through about five different arguments against geocentrism and also look at the language that young-Earth creationists use to argue against geocentrists.

I added feedback to this episode again, almost catching me up, covering several varied topics including potential future episodes. There’s also an announcement about the episode schedule.

Podcast Episode 152: Modern Flat Earth Thought, Part 3 (Young-Earth Creationists Debunking Flat Earth)


Wow! Young-Earth Christians
Still get some science correct:
A flat Earth is wrong.

Finally out, the second episode for November 2016 just before December hits, is another flat Earth episode. In this one, I make a positive case for Earth being round rather than a negative case for it not being flat. It’s rare that I do these kinds of episodes, but I thought this one in particular would be interesting because I use a young-Earth creationism website to make the argument. As young-Earth creationists tend to reject a lot of modern science, I thought this an interesting pairing. Lots of different lines of evidence are made, including eclipses, ships at sea, parallax, and star visibility.

There are three additional short segments in this episode, the first being logical fallacies (where I went through, very briefly, the three that were talked about in the episode; this was completely unscripted, unlike normal), second being an announcement about why the episode was late (depressed about the US election, then got sick and you may be able to hear a stuffy nose in the episode), and third being feedback: No, I’m not going to debate a flat-Earth proponent.

And, no episode would be complete without microphone issues. I have a new computer I was using and it sounds like when I started doing the three smaller segments, every time I would pause the recording and then re-start, there was some static. Fun times.

Podcast Episode 150: Is Dark Matter Liberal Pseudoscience?


WTF is this
“Dark Matter” stuff, anyway?
Lib’ral poppycock?

Getting away from Earth and going to the biggest scales of the universe, this episode addresses dark matter. I think I can justify it as being on such an important episode (150!!) because I spend the bulk of the episode trying to make the case to you, the listener, that dark matter is real science, in contrast with pseudoscience.

There are two additional segments in this episode: Logical fallacies and two announcements, including an announcement about the release schedule (duh — it’s not exactly on the 1st and 16th of the month).

I also must apologize for the audio – again – on this episode. Only in the editing process did I hear that it sounds horribly muffled/garbled, especially during the first 6 minutes. I’ve had issues with my Blue®™ Yeti® microphone ever since I bought it more than five years ago. I think it might finally be dying, but I’ll try a few things next time and test. Sigh. Thought based on the audio starting around 20 minutes in, which is when I re-started the software, I think it’s possible that I was going in through my laptop’s microphone instead of the Yeti. Again: Sigh.

Astounding Evidence that Creationism Is a “Science Stopper” – Click Here to Find Out How, with Pluto and Friends!


Okay, so I’m not great at the click-bait headlines.

I was glancing through some of the young-Earth Creationist mainstream sites, as I do with some regularity, and I came across the Institute for Creation Research’s “Looking Back at Pluto” by Jason Lisle. Being involved with New Horizons (though this blog is completely separate from that work/employment), and given that Dr. Lisle graduated from the same school and program I did (but a summer before I got there), I had to click.

Jason goes through some of the interesting things we found at Pluto. In particular, he highlights: (1) The craterless (as far as we can tell) Sputnik Planum area (which he mistakes for Tombaugh Regio), (2) the polygonal terrain in Sputnik Planum that is likely due to convection, (3) giant ice mountains and cliffs and canyons, (4) potential cryovolcanoes, (5) dark red area at Charon’s north pole, and (6) some of its small satellites spin really fast.

For Realz scientists are studying these features, developing hypotheses to explain them, and testing those in the lab and/or with the data returned by New Horizons. And some of them just aren’t mysteries at all because Jason hasn’t done his homework.

For example, for point (1), going in we expected that Pluto may be devoid of many craters because its surface is constantly sublimating (turning from ice to gas) as material gets transported around the body from the summer pole to the winter pole. (Pluto, like Uranus, is tilted on its side so right now the north pole is in constant sunlight.) Jason also said that having the encounter hemisphere be the bright “heart” was “by providence,” but it was specifically planned years in advance based on the (now primitive) maps we had from the Hubble Space Telescope — that area displayed the largest ranges of brightness, so it was the area we wanted to see up-close the most. It’s not providence, it was planning exactly the way you would when doing Real Science.

Another example is point (6), where yes, we would expect satellites to not rotate really fast because tidal effects should slow down the spin rates over long periods of time. If I can replace gravity for magnetism for a moment, imagine holding a strong magnet in place, and several inches away have a bar magnet that is on a post that it can spin freely around but it can’t get closer to or farther from the magnet you’re holding. Spin the bar magnet. It’s going to slow its spin pretty quickly to align with the one you’re holding. That’s kinda sorta how moons tidally lock and slow their spin except the force is gravity rather than magnets.

Anyway, at least one of the moons spins on its axis, fully, in about half a day. Is it young? Maybe possibly but unlikely … but that particular moon also has giant craters on it, so it’s just – if not more – likely that it recently (as in within the last few million years) got whacked by a large piece of debris that simply spun it up, increasing its rotation rate.

I can’t discuss papers that have been submitted by other authors on the team, but there are very plausible, natural explanations for several of the other features Jason lists, that are currently undergoing peer review, with conclusions based upon the available evidence.

As for the attempt at click-bait title? Here’s how Jason ends his article:

These are perplexing problems for secular formation scenarios. However, Christians delight in seeing the Lord’s creativity continually revealed.

In other words, his brand of Christians just STOP at the observation, attribute it to their god, and move on. How is that not a science stopper?

“They Hate or Fear Me” — The Refrain of the Pseudoscientist


I like to argue. I was never on a debate team, but I would get worked up over things whilst growing up, in college, or graduate school over which I had no control nor power to affect. A common refrain of my father’s, in response to that was, “Harbor your emotional energies.”

Fear and hatred are powerful emotions. As soon as you use observe them in conversation, it colors the entire tone. Just the use of the terms affect your own emotions.

Emotion is also a much easier response than logical thinking. It comes from a more basic, instinctual part of the human brain than conscious thought. Rather than try to address an argument or claim with thought, it’s simply easier to say that the person making that claim hates or fears you, immediately appealing to your audience’s own more instinctual level of lack-of-thought.

That, I think, is part of why we often see that from pseudoscientists when skeptics address their claims. I saw it a lot from Mike Bara back in the lunar ziggurat days almost four years ago (see this blog post where I address the issue of manufactured “hate”). I continue to see it in other areas, such as manufactured fear by anti-GMO or anti-vaccine proponents, appealing to the emotion of fear rather than a logical argument for their position.

And tonight, Ken Ham over at Answers In Genesis (AiG) which is building a claimed replica of Noah’s Ark in Kentucky, USA, has created a new term: Arkophobia.

I really don’t want to link to AiG, so I won’t. But the thrust of the post is this:

The bottom line with the secularist opposition? Arkophobia is so widespread because “the heart is deceitful above all things, and desperately wicked; who can know it?” (Jeremiah 17:9). Secularists are in rebellion against their Creator. The fact that He has the right to tell them, through His Word, what is right (e.g., marriage is one man for one woman) and what is wrong (e.g., abortion is murder) angers them.

Secularists oppose the Ark because they are afraid of the Ark’s goal: to proclaim the everlasting gospel.

That’s right: Ham is claiming that people who are against him building this ark are against him because they hate him.

It’s so much easier than really answering why they spend millions of dollars on a theme park rather than give it to the poor, or answer legitimate questions about potential fraud in trying to get tax incentives.

How Answers in Genesis Ignores Reality, Pretends You’re Dumb, to Get Money for Its “Ark Encounter”


I think in addition to my attempt to be leaner and faster on this blog in 2016, I’m going to be more direct. Hence the title of this blog post.

For those who don’t know, Answers in Genesis (AiG) is probably one of the three biggest anti-think tanks for young-Earth creationism in the world. They have a large creationism museum in Kentucky, about a 45-minute drive from where I grew up a bit north of Cincinnati, Ohio. They are currently building an “Ark Encounter” theme park based on, as you can probably guess, the Judeo-Christian story of Noah’s Ark.

I’ve been following The Friendly Atheist blog posts about this for several years. To be direct, based on their reporting, AiG has been trying to break the law many, many times during the building process. And it’s mostly all having to do with money.

In effect, they can’t build it on their own. They don’t have enough. So they’ve been trying to get tax breaks and other things to help them build. Problem is (for them), even in Kentucky they sometimes respect separation of church and state and refused to let a religious organization that would discriminate based on religion have access to public funds.

So, as an example, they were eligible for state funds of some sort several years ago so long as they would not discriminate in their hiring. Then, someone (I forget, possibly the ACLU) pointed out that all employees would have to be hired through the AiG creation museum and hence sign a statement of faith to prove they are religious. They got smacked down and the money was taken away.

Now they have a new scheme. And, this was just pointed out in a large essay in Newsweek by journalist Lindsay Tucker. Tucker demonstrates how AiG has been manipulating things to, in the end, still get taxpayer money to support their very clearly religious endeavor.

Ken Ham, the guy in charge of AiG, hit back at Newsweek by manipulating information under the assumption that you are stupid.

I found out about this because The Friendly Atheist blog has a very lengthy post by Tracey Moody hitting back at Ken Ham. Here’s an excerpt, where “TIF” is the tax breaks, and the double-block is from Ken Ham’s blog post:

Ham insists on describing the TIF in a condescending manner in his post, even conceding that he hardly understands it himself. But not understanding a topic never stopped him before. Why start now?

Most people do not understand this complicated incentive (called Tax Increment Financing) that is common across the nation, and I hope I won’t lose you here. …

Now, we simply don’t mention the TIF to reporters because perhaps 1 in 1,000 readers would even know what it is, it is highly complicated, and I don’t understand it all myself. …

At the risk of your eyes glazing over regarding this TIF matter…

He’s setting the stage to make us feel too dumb to understand what’s going on — the same trick his whole Creation ministry is based upon. But it’s not as complicated as he makes it sound.

I recommend reading it if you have the time. I thought it was very informative and clearly demonstrates how AiG is manipulating things.

As for why it’s on this blog, well, I deal with young-Earth creationists manipulating science on this blog quite a lot. This isn’t science, but it’s perhaps just as important – if not more-so – than science because it’s public policy and it’s tens of millions of dollars that is currently going to a discriminatory, manipulative religious organization. Fortunately, I don’t live in Kentucky and my tax money is not directly contributing to this effort. But I hope that if any of you do live in Kentucky, you will voice your concern to the appropriate legislators.

Podcast Episode 138: New Horizons Pluto Encounter Conspiracies, Part 1


New Horizons’ pass
Through the Pluto system: Lots
Of crazy ensued.

FINALLY! It’s out! Only 3 weeks overdue! The “August 1” episode is about the New Horizons mission to Pluto and some of the conspiracies and pseudoscience and bad media reporting related to it.

To be fair, all of these I have written about in my 11-part series. However, I know some people never read blogs and only listen to podcasts, and vice versa. So, I’m double-dipping. I don’t care. 🙂

And it’s late at night, so I’ll close this brief post out by saying that I was recently interviewed on Steve Warner’s “Dark City” podcast, which you can directly listen to at this link. If you liked it, make sure you tell Steve by contacting him through his website.

#NewHorizons #PlutoFlyby – The Pseudoscience Flows #9 — Young-Earth Creationist Take, Part 2


Terry Hurlbut Advocating Walter Brown’s Hydroplate Nonsense

In my Part 1 of this lengthy series of probably 11 posts, I talked about the machinations of Terry Hurlbut, one of the primary editors of Conservapedia and (I think) the founder of the incredibly ad-rich Conservative News and Views website that espouses über-right wing ideals and young-Earth creationism. He said that Pluto is red therefore it’s rusty therefore it formed from material ejected from Earth during Noah’s Flood.

In a follow-up post, Terry followed the same protocol as before, grabbing onto one tiny finding, saying it’s impossible to explain with modern science, therefore Pluto was launched from Earth during the Flood.

In this case, the finding was carbon monoxide (CO) ice, found in the “heart” area now informally known as Tombaugh Regio. Terry explains this by saying that during the Flood, Pluto and Charon formed by material ejected from Earth, which heated as they contracted, burning the plant matter that was also ejected. The gases released from the burning plants included CO, which fell as “rain” onto the surface of Pluto in what he claims is a basin that is now Tombaugh Regio.

Okay, I know I try to avoid ad hominem attacks on this blog, but I had to fight my brain to type that last paragraph. It’s so ridiculous, that unless one actually is familiar with Terry’s writings on his own sites and elsewhere, one would think it’s a really bad Poe or Onion article.

Terry tries to emphasize in his article that neither NASA, SwRI, nor JHU/APL (the three institutions involved in the mission) have tried to explain the CO ice. Therefore, we don’t know now and therefore Terry’s idea is the only one out there.

The thing is, we don’t have all the data taken yet. The data we do have is lossy-compressed. And scientists by their nature are very cautious about publishing hypotheses about something without doing a lot of tests of those hypotheses. AND within the mission itself, there’s the situation that it’s better to put out obvious findings now and save the possible interpretations later once we have more time to look at the better data and talk with more people and amongst ourselves.

Put in that context, it’s perfectly reasonable to expect that NASA would put out the press release about unambiguous findings of concentrations in one area of Pluto of CO (as in we found it, it’s in ice form, and it’s concentrated in one particular area) and have that be the press release, rather than add unnecessarily to it several possible models to explain it but “more data are needed, stay tuned several months until we get that data to test it.” That’s kinda a downer to close out a press release.

Institute for Creation Research Advocating Pluto’s a Comet

In a perhaps more mainstream young-Earth creationist venue, the Institute for Creation Research also has a take on the New Horizons mission. Jake Hebert wrote their article, “New Horizons, Pluto, and the Age of the Solar System.” It is a fascinating read if one looks at it from the standpoint of starting with one topic and twisting it into something completely different to argue against in a no less wrong way than most other creationist writings.

Here’s the train of thought:

  1. New Horizons went to Pluto.
  2. Secular scientists are going to tell a materialistic story without a deity about it but aren’t saying that so’s to avoid offending the taxpayer.
  3. That means we don’t understand how the solar system formed.
  4. New Horizons will yield information about Kuiper Belt Objects.
  5. These are comets.
  6. Insert everything that creationists have written about comets over the years that they think shows comets prove the universe (or at least the solar system) is less than 6000 years old.

Not only is it a strawman argument on their part, but by equating Pluto with comets means not only that everything THEY have written about comets over the years applies, but also everything that scientists – such as myself – have also written that thoroughly debunks their arguments applies.

For a taste of these, I refer you to my blog (post 1, post 2, or post 3) and/or my podcast (episode 3). Rehashing all those ideas here is gratuitous and a waste of space. And, there’s a reason why those are some of my earliest blog post and earliest podcast episode: They’re simple to debunk.

Answers in Genesis Telling You Half-, Leading Truths

Finally, another of the Big Three creationist institutions is Ken Ham’s Answers in Genesis. Danny Faulkner wrote their article on New Horizons, “Pluto’s Surface Is Young!”

Sigh.

Here is the first argument that Danny is making: Pluto has relatively few craters, therefore it must be young:

[S]cientists have found far fewer craters than they expected. […] Being far from the sun, Pluto ought to be very cold and hence not have experienced recent volcanism. Any primordial heat would have long ago dissipated, if the solar system were 4.5 billion years old. [… T]here ought not to be any significant geological activity sufficient to remove craters on Pluto’s surface. Compounding this problem for a 4.5-billion-year age for the solar system is the fact that Pluto is located in a particularly crowded part of the solar system. […] Therefore, Pluto ought to be undergoing impacts today at a higher rate than most other objects in other portions of the solar system. Planetary scientists who are committed to belief in a 4.5-billion-year-old solar system are at a complete loss to explain the lack of craters on Pluto.

Part of this is exactly the same argument (at least in part) that I debunked here, in my post about Venus, several years ago: “Venus and the Battle of Uniformitarianism (A Creationist Argument).”

First, Pluto does not have ZERO craters. It has many; it’s just Tombaugh Regio that has no unambiguous craters in the region that we’ve seen with the lossy JPG artifacting covering it. That means it likely has no craters >10 km in diameter, meaning it could still have plenty that are smaller.

Second, the whole way we get our crater chronology starts from the moon (which Danny acknowledges, and he actually gives a reasonable overview of the subject). We do see heavily cratered areas of Pluto. So if we see some areas that have a huge number of craters relative to other areas, it just means that the one with few craters (or maybe none) is much younger. How much younger, though? If Danny wants to say that the heavily cratered areas are 6000 years old, does that mean that the “heart” region of Pluto was created yesterday? Again — see the Venus blog post.

To bypass some more of the quote and get to the last statement, this is common among creationists: God of the Gaps. Set up a scenario and say someone can’t explain something and then say GodDidIt. Except, we have plenty of ideas of why there may be no craters over some parts. One of the main ones has to do with the second argument (in three paragraphs): The atmosphere. It’s tiny, but it cycles. Pluto is tilted almost like Uranus, except more. So for 124 years we have one pole facing the sun, and for 124 years the other. During this time, it’s likely that the ices on the surface near the sunward pole sublimate (turn from solid to gas) and some get deposited on the pole that’s in night. This gives you a “surface” that is literally no more than a hundred years old.

In fact, going into this, I was warned that several models predicted that there may be very few craters on Pluto simply because of this process, of not only ices being deposited as many, many layers of frost, but also because when they sublimate, they are removing that surface that had been cratered! So some predictions going in were that Pluto may have a few very large, shallow craters, but nothing else. Obviously that’s not the case, Pluto is more interesting, but to say that we “are at a complete loss to explain the lack [not!] of craters on Pluto” is bullocks.

Here is the second argument that Danny made: Pluto is outgassing nitrogen, and therefore it’s young because it is a body of finite size and because there should be some activity that releases the nitrogen.

Yes, Pluto was found to be outgassing molecular nitrogen gas. Though “outgassing” is the wrong word here — perhaps an honest mistake, but it’s wrong nonetheless. It’s that nitrogen gas is escaping from the surface, not being outgassed from below the surface (that we know of). So this is a classic creationist argument: Take the current rate for something, multiply it by 4.5 billion years, and claim it’s impossible. They do that with Earth’s moon. But in this case, Danny didn’t even do that simple math, even if it is wrong (the current rate may not be what it was in the past). 500 tons per hour means very roughly 2*1019 kg over 4.5 billion years. Pluto is 1.3*1022 kg. That means it would have lost a mere 0.15% of its mass due to nitrogen escaping over 4.5 billion years if the current rate has been the rate for 4.5 billion years.

Not a problem.

The third argument has to do with the very tall, 3.3 km high mountains observed on Pluto, where Danny argues that if Pluto is warm enough to have geologic activity to account for those first two things, it can’t be cold enough to support ice mountains.

The mountains are interesting. I don’t even remember if there are solid ideas yet in the team as to how they may have formed, but this is yet another example where scientists look for something to explain an observation, and creationists leap to GodDidIt. Regardless, though, both of the prior two arguments can be explained at least in part by atmospheric processes rather than geologic, therefore this is moot.

Finally, he argues that Charon has fewer craters than expected, and a large chasm, therefore it’s young, too.

Problem if we take this approach: How can Charon be older than Pluto? If we’re using the metric of craters (and incorrectly per the standard young-Earth creationist), and Charon has more than Pluto, then Pluto is even younger than 6000 years old, right? What is he trying to say here, that Pluto formed a few minutes before Clyde Tombaugh discovered it?

I’m also not quite sure where he’s getting that Charon has fewer craters than expected. I don’t remember this being discussed, but it’s possible I missed it. A lot of the issue for Charon (and Pluto, for that matter) is our ability to identify craters in these images. Most imaging is with the sun almost directly overhead. Meaning we can’t pick out craters very easily. Especially when all we have is lossy, JPG-compressed images. Think of photographing the full moon of Earth and then compressing it to 100 kb to send to your grandmother who’s running Windows 95 with a 56k modem. Not easy.

Charon probably has more craters than Pluto (no atmosphere). But our ability to find them right now is significantly hindered. That in mind, I’ve already identified a few hundred. Same on Pluto.
