Podcast Episode 153: What Is Radiation?

“Radiation” is
As common in life as ’tis
In pseudoscience.

This is one of those basic science episodes where I tried to provide solid background to a typically misunderstood concept that is beloved by pseudoscientists: Radiation. I go through what radiation is and is not, different kinds of radiation, what it means to say that something is ionizing vs nonionizing, and the effects of thermal radiation. It’s a longer episode, clocking in at 51 minutes.

There are two additional short segments in this episode, the first being logical fallacies where I discussed the nautralistic fallacy, and the second being feedback where I finally addressed Graham’s feedback about the Catholic Church and a round vs flat planet.

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.

Podcast Episode 148: (BONUS) X-Rays from Pluto

Does discovering
X-rays from Pluto change all
We know and hold dear?

First interview episode since The Return, an interview about the discovery of x-rays coming from the vicinity of Pluto. I talk with one of the main authors of the paper announcing the observation of x-rays from Pluto, and we discussed why the find is not severely unexpected, and while it’s interesting it is not something that is completely unexplained. In fact, there’s a very good, natural explanation.

As what was intended to be a 5-10 minute interview ended up running about 50 minutes. Hopefully it was worth it. Note that this was recorded really ad hoc, outside on a university campus, using both an iPod Touch and Samsung Galaxy S5. Interestingly, the iPod performed better relative to noise, but it had a low-end filter; the Samsung had a high-end filter. Therefore, I lined up the audio precisely and combined both so you get better audio, and I tried to lower the relative intensity of each recording if one was picking up the wind more than the other.

There are no additional segments in this episode.

I hope that you enjoy this episode.

Richard Hoagland: As Slippery in 1998 as He Is Now

I suppose I might get called a “troll” for that kind of subject line, and I also am at risk for this post seeming to be an ad hominem, but I think it’s important to show how pseudoscientists argue when confronted by, well, any challenge to their claims. “Slippery” is the thought that came to mind yesterday while listening to an old Coast to Coast AM episode from May 26, 1998.

During the interview, Art Bell brought up one of Richard Hoagland’s critics, Ralph Greenberg, then and now a mathematics professor at the University of Washington. Prof. Greenberg heavily criticized Richard’s mathematical claims about the Cydonia region of Mars, something that I have done, as well. Basically showing that Richard was drawing lines that he claimed were significant and ignoring ones that weren’t.

Art said that Prof. Greenberg was sending him e-mail after e-mail and wanted to debate Richard Hoagland, on-air. What followed was many, many minutes of what really is best described as Richard being “slippery.” Richard ended up really arguing, in the end, that the math he claims to have found at Cydonia is meaningless because he’s moved beyond that, and Prof. Greenberg was still mired in the past and refused to consider any new arguments about things Richard was making. Which I classify as “slippery” – as well as, in hindsight knowing how things have played out over the subsequent 17 years, “disingenuous.”

Basically, Prof. Greenberg wanted to debate a specific claim. Richard wouldn’t even entertain that. Because he’s “moved beyond” it (despite clearly not). Whenever Art tried to bring it up in a different way, Richard kept saying different things to that effect, and he misrepresented Prof. Greenberg’s claims.

And, Richard does the same thing today. An excellent example is from 2010, when Richard claimed that an earthquake happened right at 19.5° on Earth. The actual center was at 18.5° N latitude, not 19.5°. When called out on that, Richard said, “I was thinking of geodetic latitude – not geographic – the latitudes change because the Earth is not a perfect sphere, it’s an oblate spheroid.”

Slippery. Why? Because it’s something that sounds plausible to almost anyone. It’s a term that seems like it could be correct. Problem is, as Expat pointed out at the time, this shifts his latitude by a mere 0.1°. Not 1.0°. And, if that were the case, everything else that he claims is at 19.5° (because that’s a magic number for him), he suddenly loses because he used geographic, not geodetic, latitude.

They are completely different kinds of examples, but I think that this illustrates well that while I may disagree with practically everything Richard Hoagland has said or done over the years, I must admit that he’s quick on his feet and clearly able to slip through peoples’ lines of defense, getting them to move on to a topic more favorable to him.

Podcast Episode 137 – Why Earth Is Old, Without Radiometric Dating

Finding age of Earth
Does not require just Rad-

The next episode! It was actually recorded three weeks ago, but I was so busy with New Horizons that I never got time to edit and then post it. So, here we go, the different ways scientists got minimum ages for Earth – without using radioactivity as a technique.

Plus two feedbacks! For a half-hour fun-pack!

Podcast Episode 133: Element 115 and the Credibility of Bob Lazar’s Claims

Existence: Does it save Bob
Lazar’s U’FO claims?

A return to the roots of the podcast: A simple exploration of a claim, and what was found. Sort of. The first third of the episode is a look into the story of Bob Lazar, a man who is often credited (in part) with re-invigorating the UFO community in the late 1980s / early 1990s. It’s important for context, because embedded within that story is a general lack of credibility for his claims.

Enter element 115, which when it was discovered in 2003, became a rallying point for Bob Lazar’s supporters: The very existence of something that had not yet been discovered when Bob Lazar made the claim, means that his claims must be true. We see this a lot of times in the UFO field, but I really focused in this episode on this specific claim and the specific set of claims about element 115 made by Bob Lazar, before its “mainstream” discovery.

This episode does get a little technical because I talk about some basic particle physics, but I think it’s on par with most of my other episodes in terms of technical jargon and concepts.

And, that’s about it. There’s a short logical fallacy segment, where I ask your help in identifying the main logical fallacy for the episode, which I’ll then discuss next time.

It’s also important to note that the podcast is on Stitcher, and I should’ve checked my stats before I mentioned them at the end of the episode: I’m now on 33 peoples’ playlists and I’m ranked in the 3000s, not on 22 peoples’ playlists and ranked in the 5000s. Not bad for only being entered in late March and not doing much to promote it.

Podcast Episode 132 – In Search Of Planet X (Live from Denver ComicCon)

In Search: Planet X.
An overview of common
Ideas about it.

This episode is another recording of one of my live presentations, modeled a little after Leonard Nimoy’s “In Search Of” television series. It was presented in front of a live audience at the Denver ComicCon on May 24, 2015, to about 75-100 people. I was bordered on two sides by other sessions that had more people and a lot of laughter, so I played to that a little bit when there were opportune moments. I also suffered a minor A/V issue in the middle but recovered, so you’ll hear some fumbling there.

Unfortunately, there is also some popping that comes in about 10 minutes into the recording. I exploited all the filters that I know of in my Audacity toolkit, and they are less of an issue than they were, but they are definitely present.

I also need to announce that it is that time of year when work is going to get crazy, so episodes may come out a little less regularly, especially during July. I’m still going to keep to the two per month schedule, but they may not be out on exactly the first and sixteenth of the month.

And with that in mind, I have to head to the airport in 45 minutes for more work, after just being back home for 3.5 days. So …

Podcast Episode 125: The Black Hole Conspiracy

Black holes: Are these dense,
Massive objects for realz, or
Are they just Sci Fi?

This is a bit different from a straight-up old-school “debunking” episode where the emphasis is more on the process of science and process of elimination rather than solid, cannot-be-dismissed evidence for something. That’s because, by definition (we think), black holes cannot be directly observed. That’s why I use a part of a blog post by Mike Bara as a very rough outline to go through some of the theoretical reasons for why we think black holes exist and then some of the observational evidence from material interacting with the theoretical objects.

This episode continues the Logical Fallacies segment and introduces you to the Burden of Proof fallacy. Which is a tricky one. There are also some old stalwarts like Argument from incredulity, argument from ridicule, ad hominem, straw man, and argument from authority.

And, for the first time in what seems like a year, there’s Q&A!!!

I’m still doing my listening “research” for the Hale-Bopp episodes, which is looking like there’s so much material that I may turn it into a three-parter. We’ll see. Hard to say at this point. It’s slated to be the next episode, but I may have to postpone that if I haven’t finished listening in time, and I’ll do a different episode instead. I’m also trying to line up at least two future interviews, but given past experience, I’m loathe to announce them before they’re recorded.

The Deathbed Confession Phenomenon, and I’m Blogging at JREF’s Swift

As I continue to emerge from my seclusion from writing 5 grant proposals, a new development is that I am now included in the roster of bloggers on the James Randi Education Foundation (JREF) Swift blog. I’m not entirely sure how often I’ll be able to do it, but with 400-1000 -word posts and me already doing the weekly ATS 3-hour radio program Saturday nights, hopefully some time overlap can be arranged.

That said, my first post is about deathbed confessions, and why I find them unconvincing in terms of revealing anything outside the mainstream. I’m going to include the posts here in part because the Swift blog comments are closed. The posts here will not have been edited from what I send Sharon Hill (who does the actual posting) or have the images, so go there for the pretty pics.

Since this is my first Swift post, I wanted to give a brief introduction. I’m a self-termed “astro/geophysicist” with a Ph.D. in geophysics but a background more in astrophysics. Given my background, I tend to focus on pseudoscience and skepticism as applied to astronomy, geology, and physics. One regular activity of mine is that I’m a member of the studio of “ATS Live,” the premier three-hour live weekly show of the Above Top Secret website (one of the most popular conspiracy websites in the world); I’m the token skeptic.

On last weekend’s show (October 25, 2014), one of the topics we discussed was the deathbed confession of “Area 51 scientist,” Boyd Bushman. Within a few weeks of his death this past August, Mr. Bushman was recorded in numerous clips making various claims about how he worked on things such as antigravity, UFOs, and other classic pseudoscience claims related to what could be loosely termed, “new physics.”

I think this is an excellent example of why I find the “deathbed confession” phenomenon completely unconvincing, especially as related to paranormal-type claims.

People who want to believe tend to cite two reasons that deathbed confessions should be considered good evidence for their claims. First is the classic argument from authority, especially in the case of Boyd Bushman who’s reasonably well known in the UFO community and “was a retired Senior Scientist for Lockheed Martin.” He was awarded patents and defense contracts. Sounds impressive.

To be brief, the argument form authority is meaningless in terms of the veracity of the actual information; claims and information need to stand on their own and be verified regardless of the person who is making it. My favorite example is that Isaac Newton who (by most metrics) founded modern physics, believed in alchemy.

With this in mind, I don’t even need to start on the path of investigating Mr. Bushman’s claims of employment and background, which many people have called into question.

The second reason people tend to believe deathbed confessions is, “they have nothing to lose!” After all, the person making the deathbed confession is – barring something miraculous – dying. Being killed by the Men in Black at that point is no longer a threat because they’re about to die anyway.

While this certainly makes sense, there are plenty of other reasons why a deathbed confession would actually not be reliable. For one, at least for those who are older and close to death, senility can play a role. It is a normal part of aging, and for the record, Mr. Bushman was 78 when he died. I’m not claiming that senility played a role in this case, I’m merely raising it as a complicating factor of an older person’s testimony.

That aside, a deathbed confession can be a good time to solidify one’s reputation and use the deathbed confession phenomenon and the belief in its veracity to double-down on the claim to increase peoples’ belief in it.

The thinking could easily be, “People really believe that people are 100% honest on their deathbed, so I’m going to make sure I go out with a ‘bang’ and make my claims yet again. People who didn’t believe me before might this time because they’ll think I’m telling the truth ’cause I’m about to die.”

However, in addition to explaining why the common reasons to believe deathbed confession testimony are unconvincing, there’s a better reason why the testimony is not useful: They’re doing it wrong.

Let’s say I had a bunch of secrets of exotic physics and decided to do a deathbed confession. Here’s what I would say: “I’ve been working on antigravity and warp field physics for the last 50 years, in secret, with the US government.” Then, instead of showing photos of a spaceship or a blurry alien – if even that as opposed to just speaking to the camera – I would add: “And, here are the equations. Here is a diagram for how you build a device. Here is a working model. Here is exactly how you put everything together.”

In other words, it shouldn’t matter who I am, what my experience is, or what pretty (or ugly) picture I show. What I need to show is HOW to do it. Saying something doesn’t make it so. I need to give enough information for someone else to verify it and duplicate it. Otherwise, what’s the point? To show I’m smarter than everyone else and I’m just letting you know that before I die?

That’s why I find this whole deathbed confession thing unconvincing and, perhaps more importantly, unuseful: We have no more information than we had before. We have no way to verify any of the information claimed. No way to test or duplicate it. At *best*, we have another person claiming this stuff is real, and while he or she may be proven out with the passage of time, their “confession” contributed absolutely nothing to that advancement.

Until then, it’s no better than any other pseudoscientific claim.

Podcast Episode 116: The Electric Universe, Part 2, with Dr. Tom Bridgman

Sun models from the
Electric Universe. Do
The predictions work?

Practically on time comes part 2 of the two-part overview of the Electric Universe. This one is also a bit heavy with the math, so I recommend heading over to Tom’s site for more information and many, many more details.

So, um, with the deadline for a major grant program coming up in a few days, that’s it folks!
