The Reality Check Podcast Episode 348 – Me on Exoplanets, Others on Other Stuff


Episode 348 of “The Reality Check,” a weekly Canadian podcast that explores a wide range of scientific controversies and curiosities using science and critical thinking, is posted, and I take the first (and longest) of the three segments, where I discuss exoplanets.

I was originally contacted to discuss this topic because the hosts had some skepticism about the hype that we get every few weeks or months about how we are just on the verge of discovering an Earth-like exoplanet. The issue is that “Earth-like” can have a lot of different requirements and qualifications: Do you mean Earth-sized? Earth-like orbit? Habitable zone around the star? Atmosphere like ours? Etc.

Unfortunately, for my linear thinking, that meant I had to spend about 20 minutes going through an overview of how we find exoplanets, what the limitations are of each technique, and what information about the planet each technique can give us, and how different techniques and follow-up observations can be used to give complementary information (for example, if you detect an exoplanet using the transit method, you can use the radial velocity method to get the mass of the planet, and if you detect an atmosphere with the transit method, you could use spectroscopy with the Hubble Space Telescope to measure the atmosphere’s composition).

And for the record, when I practiced the segment without interruptions, it was 11 minutes. It stretched into almost 30 minutes on the show. And for regular listeners of TRC, you should recognize a quote from former-host Elan (I think) that I incorporated into the end of my segment.

It was toward the end that I finally got to the question about whether media reporting is hype. And, to put it concisely: Yes. But with that said, we really do, at this point, finally have the technology to detect an Earth-sized planet (and have) in an Earth-like orbit (have not) with potentially an Earth-like atmosphere (have not, and this tech may not *quite* be there, but if it isn’t, it’s close).

I haven’t listened to it yet, but of course I was there when it was being recorded, and I don’t remember embarrassing myself too much. They do tend to all talk more slowly, though, when recording at 1x versus how I listen to podcasts at about 1.2–1.3x. Also, three of the 4 outtakes (they have outtakes at the end of the show) are things I said or contributed — I guess I was humorous (or humourous? since it’s Canadian?).

I will add that doing a panel show is VERY different from doing a monologue as is my normal podcast. Or even doing an interview on the podcast. The dynamics are (obviously) completely different, and you almost have to build in pauses to what you’re talking about in case of questions from others. I think I stepped over some people, too. For example, there was one point maybe half-way through my segment where I stopped and asked if anyone was there because I wanted to make sure my internet connection (and theirs’) was still up since we had been having issues. They were all there, but then there were something like 3-4 questions that they asked because they had just been developing while I was talking and not pausing enough to let them ask.

If they’re kind enough to invite me back, I’ll keep this in mind and build that in. And work more at editing myself down.

Oh yes— There were two other segments. One was a guessing game as to “which came first,” while the other segment was about whether you should plan to visit Israel last if you go to the Middle East because other countries won’t let you in if you have an Israeli stamp in your passport.

Podcast Episode 131 – Clip Show #3: Blood Moons, Ceres’ Bright Spots, MESSENGER’s Death, and Funding in Science Follow-Up


Blood moons, science cash,
And spacecraft conspiracies
Are topics du jour.

Clip Show #3 is a big catch-up on several miscellaneous topics: The latest lunar eclipse, Ceres’ mysterious bright spots, MESSENGER’s death plunge into Mercury, and a large follow-up to episode 126 which was my interview with Dr. Pamela Gay about funding in science. This episode also had a logical fallacy section – cherry picking and anomaly hunting – and a feedback/Q&A about whether NASA has created a Warp Drive, and finally my long-foreshadowed tribute to Leonard Nimoy, with how he or his characters influenced myself and you in some way.

There’s really not too much else to say about this episode. The next one will likely by about Big Bang Denial (along similar lines to episode 125 about Black Hole Denial and a future one about Dark Matter Denial). And, this Friday/Saturday, I should be back on “The Reality Check” podcast discussing exoplanets and that we’ve been on the cusp of detecting an Earth-like planet … for many years.

Podcast Episode 130: Dealing with Pseudoscience at Scientific Conferences (and #LPSC2015)


The Iv’ry Tower
Of science: Who can get in,
And who remains out?

Second in the three-part series: Have you ever wondered how decisions are made about who can and who cannot present at a scientific conference? Then listen to this episode! I interviewed Dr. Dave Draper, who chairs the program selection committee for the largest annual planetary science conference in the world. We talked about a lot of things, from the basics on the (incredibly minimal) requirements of submitting a presentation request to how decisions are made. We also discussed a few hypotheticals using real-world examples of pseudoscience that I’ve talked about on the blog and podcast.

The episode, like most of my interviews have been, is nearly an hour long, but I found it an interesting discussion and learned some things, so hopefully you will, too. There were not other segments in this episode, though I did do a follow-up because of what happened to air on Coast to Coast that evening, a mere 12 hours after Dave and I had finished recording, and it led me to disagree with him at least a bit on one point.

The next episode is going to be a bit of a catch-up on things that have been piling up since I started the Hale-Bopp saga back in March. I’ll do a bit of pseudoscience with whether or not the lunar eclipse we had in April was really a full one – and implications for the “Blood Moon” crapola – a lot of feedback including discussion about some points raised by Pamela Gay in episode 130, and the Leonard Nimoy tribute.

Podcast Episode 129: The Saga of Comet Hale-Bopp and its Fugacious Companion, Part 3


Great Comet Hale-Bopp,
Part 3: The cult members’ death
And continued bull.

Second in the three-part series: The saga of the great and powerful Comet Hale-Bopp and the conspiracy, mystery, intrigue, lies, schemes, hoaxes, and suicides that accompanied it. The idea came when I started listening to a new Art Bell set of interviews that I had obtained, and I realized early in the episode (November 14, 1996) that I was listening to THE interview that started the whole thing. I found another dozen or so interviews and decided to make an episode out of it that has blossomed into three episodes.

The three episodes are meant to be stand-alone in that they don’t need the others to be understandable. But, put them together and they tell the story in a lot more depth. This third part is all about the “meat” of the issue: The tragic suicide of the cult members of Heaven’s Gate. I devote the first half to them and the second half to a discussion of the continued pseudoscience related to Comet Hale-Bopp that persisted after their deaths.

The logical fallacy of the episode is the Straw Man.

Looking ahead, the next episode is an interview with Dave Draper on potentially pseudoscientific conference submissions and what the program committee of a conference does when they get work that appears to be pseudoscience.

Looking back, I was a guest panelist on episode 342 of The Reality Check podcast. It was fun, and I recommend checking them out.

And, finally, I plan to do a small tribute to Leonard Nimoy on the episode 131, due out on May 1. The tribute will be from you: If he or any of his characters affected you (especially as perhaps related to an interest in science or astronomy or critical thinking), please send in a few sentences. Or, record no more than 30—60 seconds and send the file to me.

Podcast Episode 128: The Saga of Comet Hale-Bopp and its Fugacious Companion, Part 2


Great Comet Hale-Bopp,
Part 2: On remote viewing
The comet’s partner.

Second in the three-part series: The saga of the great and powerful Comet Hale-Bopp and the conspiracy, mystery, intrigue, lies, schemes, hoaxes, and suicides that accompanied it. The idea came when I started listening to a new Art Bell set of interviews that I had obtained, and I realized early in the episode (November 14, 1996) that I was listening to THE interview that started the whole thing. I found another dozen or so interviews and decided to make an episode out of it that has blossomed into three episodes.

The three episodes are meant to be stand-alone in that they don’t need the others to be understandable. But, put them together and they tell the story in a lot more depth. This second part is about one of the primary drivers behind the Hale-Bopp companion, Courtney Brown, and his remote viewing claims. While he provided the hoaxed photographs to Art Bell and Whitley Strieber (per Part 1), he claimed that all of his evidence for the companion was “good data” and based on remote viewing.

Part 3 will be on the Heaven’s Gate cult and aftermath and continued conspiracy, including a brief entry by Richard Hoagland.

I have decided that, while I may do my interview with Dave Draper on potentially pseudoscientific conference abstracts before Parts 2 or 3 are finished, I will wait to put it out, such that Parts 1-3 will be back-to-back-to-back.

While there was one logical fallacy in the episode (argument from authority), I instead used the segment to discuss part of the skeptical toolkit: The BS Meter. And, what should trigger it and what you should do about it. The bottom-line is that you should question any claim that sets off your BS meter, and even when something seems innocuous and small and not even part of what could have led to the anomalous result, you should still check it.

And, finally, I plan to do a small tribute to Leonard Nimoy, no earlier than April 1. The tribute will be from you: If he or any of his characters affected you (especially as perhaps related to an interest in science or astronomy or critical thinking), please send in a few sentences. Or, record no more than 30—60 seconds and send the file to me. I will read/play them either on episode 130 or 131.

Finally, this episode is coming out a bit early because I’m leaving for a week for a planetary science conference and won’t be able to do much of anything else while I’m there.

Podcast Episode 127: The Saga of Comet Hale-Bopp and its Fugacious Companion, Part 1


Great Comet Hale-Bopp,
Part 1: On the claimed photos
Of your companion.

I’ve been working on this episode for awhile: The saga of the great and powerful Comet Hale-Bopp and the conspiracy, mystery, intrigue, lies, schemes, hoaxes, and suicides that accompanied it. The idea came when I started listening to a new Art Bell set of interviews that I had obtained, and I realized early in the episode (November 14, 1996) that I was listening to THE interview that started the whole thing. I found another dozen or so interviews and decided to make an episode out of it. About three months and over 10,000 words of notes and transcripts later, this is the release of Part 1 of what will be a three-part series on Hale-Bopp.

The three episodes are meant to be stand-alone in that they don’t need the others to be understandable. But, put them together and they tell the story in a lot more depth. This first part is about the image – the “hard science” – claims about the companion. Next one will be on the remote viewing claims and aftermath, and the third will be on the Heaven’s Gate cult and aftermath and continued conspiracy, including a brief entry by Richard Hoagland.

I have decided that, while I may do my interview with Dave Draper on potentially pseudoscientific conference abstracts before Parts 2 or 3 are finished, I will wait to put it out, such that Parts 1-3 will be back-to-back-to-back.

There were two logical fallacies pointed out in this episode: Argument against authority, and correlation ≠ causation (cum hoc ergo propter hoc).

And, finally, I plan to do a small tribute to Leonard Nimoy, no earlier than April 1. The tribute will be from you: If he or any of his characters affected you (especially as perhaps related to an interest in science or astronomy or critical thinking), please send in a few sentences. Or, record no more than 30—60 seconds and send the file to me. I will read/play them either on episode 129, 130, or 131.

Podcast Episode 126: The Facts and Misconceptions Behind Funding in Science, with Dr. Pamela Gay @starstryder


The sordid subject
Of the coin: How scientists
Are – and are not – paid.

This is another episode where I don’t focus on debunking a specific topic of astronomy, geology, or physics pseudoscience, but rather I focus on a topic of misconceptions related to science in general: How scientists are funded. This is done via an interview and bit of discussion with Dr. Pamela Gay, who cohosts the very famous “AstronomyCast” podcast and is the director of CosmoQuest.

The topics are varied, but it remains focused on some of the misconceptions of how research is funded and the real process behind it. It’s also a bit depressing, but I can’t always have light-hearted topics like Planet X isn’t coming to kill you.

Since this is an interview, it is a somewhat longer episode (54 minutes), there is no transcript, and there are no other segments.

The episodes for the next two months should be focused on Comet Hale-Bopp and have a brief interlude of another interview with the chair of the program committee for a major planetary science conference, and what they do when they get submissions that seem like pseudoscience.

Podcast Episode 124: The Astronomical Distance Ladder


Measuring distance
In the Universe: A fun
Science episode!

An episode over two years in the making: The Astronomical Distance Ladder!!!!! (insert many cheers) In all seriousness, I have wanted to do this episode since autumn (August-ish) 2012, but I haven’t been able to find a good hook. Convicted and jailed felon, Kent Hovind, provided that for me on January 6, 1998, in a Coast to Coast AM episode I got my hands on. And so we have this episode. It is long. Those of you who like longer episodes, this is nearly an hour long. It did not intend it to be this long, but, well, that’s what happens when I get excited about a topic that’s not incredibly straight-forward.

I also guessed off the top of my head that an object with a redshift value of z = 1.4 would be about 10 billion light-years away. According to Wolfram Alpha, it’s 9.1 billion l-y lookback time, so take THAT, Prof. Morrison! (It’s been literally a decade since I thought about what z equals what distance, so I’m pretty impressed that I got that pretty close.)

I do want to apologize about the sound quality in this one and the variable volume levels (I tried to even them out in post-processing). I was recording during sustained 20mph winds with gusts over 50mph. So, I had a lot of background noise I was dealing with that varied in intensity.

This episode has three additional segments: New News related to a precision measurement of Saturn’s position, a new Logical Fallacies segment, and Feedback (one clarification, one negative and my response).

For the new Logical Fallacies segment, I’ll say what I said in the episode: “I’m open to feedback including overwhelming negative feedback on whether this was at all useful or is worth keeping in some modified way, and also if I’ve made any mistakes.” The fallacies discussed in detail for the episode are Argument from (Personal) Incredulity and Appeal to Ridicule. I got into how both of these are classes of Red Herring fallacies and the former is a sub-type of Red Herring, the Genetic. I also pointed out that additional fallacies in Mr. Hovind’s argument were the False Precision Fallacy, Appeal Against Authority, and False Analogy.

Edited to Add (January 21, 2015): The Raw Story has an article up today explaining a bit more about Kent Hovind, and that he is trying to testify before Congress (though he’s still in federal prison) about the IRS being a bunch of meanies.

Podcast Episode 123: The Science and Pseudoscience of Communicating with Aliens with @KarenStollznow


Karen Stollznow talks
‘Bout the issues of ET
Communication.

I wanted to start the New Year off on a lighter and different kind of topic, so I interviewed linguist, Dr. Karen Stollznow, about alien communication. This was based a bit on her TAM 2014 talk, and we got into a lot of issues not only with how communication is portrayed in popular media, but how communication is problematic amongst people on our own planet, different language groups on our own planet, and different species on our own planet. We then discussed – within that context – some people who claim they are in contact with aliens and how linguistic analysis shows the claimed languages to be poorly constructed variations on what they already know.

This interview was only meant to be a half hour long, but even after editing, it is just under an hour. That editing included removing a headset issue and two phone calls from my mother (family emergency). I tried to find a possible natural break to get it to two 30-minute episodes, but I found none: the conversation flowed very well, I thought.

There are no other segments in this episode because it is just over an hour long. The next episode should be about black hole denial.

Podcast Episode 122: Comet 67P/Churyumov-Gerasimenko and Rosetta Conspiracies


Conspiracies of
Comet 67P …
Few, but they are weird.

A timely and listener-requested episode! What’s not to love!? In the episode I talk about several of the conspiracies I’ve seen surrounding the Rosetta mission and Comet 67P. From artificiality (Hoagland makes a guest appearance) to singing so as to raise our consciousness to angelic levels when 2012 failed, I spend nearly a half hour going through 2 to 4 claims (depending on how you count them) that have been making the rounds. I also get to touch on image analysis.

There is also one New News segment this episode, and it refers to the death of the Venus Express mission around (oddly enough) Venus. The news relates to the episodes on uncertainty. Not sure what the connection is? Listen to the episode! The episode also comes in at just over 30 minutes, my target length.
