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 165: Little Things in Space


Microgravity,
True or near vacuum pressures,
Temperature in space.

A long-planned episode that gets back to the roots of ferreting out misconceptions (though three tied together): Little Things in Space!!! This episode, if you couldn’t get it from the haiku, covers the concept of microgravity, vacuum, and temperature (what does temperature mean if there’s nothing there to experience it?). There are no additional segments.

Podcast Episode 164: The World Didn’t End on September 23, 2017


Doomsday yet again!
The story of this one, though,
Has a surprise end.

A much shorter episode this time, announcing what you already know: We survived doomsday, again (yay!). But, the story of this particular doomsday claim may surprise you — it did me. But I could be wrong, so please let me know if you have additional information beyond what I found (listen to the episode for more of what I’m talking about).

Meanwhile, this is either a bonus episode or the episode for the second half of September. I haven’t decided yet because I’m not sure if I can get out another episode before the beginning of October. My 10-day vacation in Utah was great, but it requires a lot of catch-up at work.

There are no additional segments.

Podcast Episode 163: Modern Eclipse Lunacy, Part 1


Solar Eclipses:
Even in the modern day,
Lunacy exists.

Back and pumping out a 42-minute episode on some of the crazy surrounding the recent lunar eclipse, crazy that you’re not going to hear from other sources. This past eclipse on August 21, 2017, was perhaps one of the most-hyped and most-viewed solar eclipses in human history. As with any such mass-sighted event, pseudoscience is bound to rear its ugly head. In this episode, I address doom and gloom, earthquake predictions, astrologic predictions, Planet X predictions, and other topics related to the eclipse.

There’s one additional segment, and that’s about where I’ve been (literally).

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 161: Water on Earth— Coriolis and Tides


Water on the Earth:
Do tides affect you? Does the
Coriolis, too?

Another short main segment, two common misconceptions about water: Coriolis and Tides. The episode was motivated when I recently heard George Noory make the statement, yet again, about, “Since we’re mostly water, and the moon causes tides in water, doesn’t the moon affect us, too?” Or something like that. Add to it some misconceptions I’ve had before about Coriolis, and we have an episode.

I added feedback to this episode, and there’s more feedback that’ll be in the next episode. This is also the episode for the first half of April. One of these days, I’ll get back on schedule.

Podcast Episode 160: Apollo Hoax: The US Flag Waving, and the Moon of No Return


Apollo Moon Hoax:
Why does the US flag wave?
And, why no return?

A return to a tried-and-true subject of skepticism: the Apollo Moon Hoax. In this shorter episode, I discuss two of the most common claims that you may hear: Why does the US flag appear to be waving in photographs, and if we went to the moon, why haven’t we been back?

There are no additional segments in this episode, and it is significantly shorter than my recent standard. This is also the episode for the second half of March.

Podcast Episode 159: A Proposal for the Geologic Definition of “Planet,” Interview with Kirby Runyon


Definition of
Planet: Useful in science?
Or, just pedantry?

Sorry for the delay again, but I have an interview that’s just under an hour this time on a new proposal for a geophysical definition of the word “planet.”

In 2006, the International Astronomical Union sparked an uproar and furious debate among scientists and non-scientists alike when they voted for a definition of the word, planet. Numerous proposals since that time have been made for the definition of that term. Eleven years later, a new proposal has gotten a lot of media attention and in this episode, we discuss that new proposed definition. This is closer to a friendly debate style because the guest and I have different points of view on this issue.

There are no additional segments in this episode, but the interview runs 51 minutes. This is also the episode for the first half of March.

Podcast Episode 158: Getting Beyond the Photograph: Image Tricks with Dr. Tod Lauer


To peer beneath the
Photograph and uncover
What may be hidden!

Sorry for the delay, but I have an interview that’s over an hour this time on image processing. In past episodes, I have talked about how you can’t get any more information out of an image than what is in a single pixel. Dr. Tod Lauer is an astronomer who has worked on all kinds of telscopes and instrument data and has developed numerous image processing techniques over his career. In this episode, we discuss some of those and how to correctly – versus incorrectly – apply them to image data to get to the best representation of the original object, or what the image was trying to capture.

There are no additional segments in this episode, but the interview runs nearly 1hr 15min. This is also the episode for the second half of February. I’m very much hoping/trying to get the first half of March’s episode out before I leave on a trip on March 19. It will either be an interview on what’s a planet, or a normal episode on Apollo Hoax miscellaneous claims I never did an episode about.

Podcast Episode 157: Special Cross-Over with The Reality Check, Astronomy Edition


Altern’tive Title:
Yes, Virginia, there really
Is a Canada.

An episode three months in the making, a cross-over with the crew of The Reality Check (Cheque?) podcast: Astronomy! I had wanted to have the group on this podcast because they had been so generous over the last few years having me on several times, but I couldn’t figure out a good angle. Then, someone (sorry, forget who, but it wasn’t me) suggested we just do a TRC-style show but with astronomy topics. The Reality Check, for those of you who do not know, is a weekly Canadian show that is now just under a half-hour that has four hosts and typically three completely random segments per show. It’s almost nine years old, and it’s kept with that basic format throughout its entire run.

For almost all the segments, I asked them to choose topics from various requests that I’ve gotten over the years. We also did a quiz, in TRC style, that gave me a new appreciation for those on the show who conduct those quizzes every few episode. It clocks in at a little over an hour, which is still short considering that my original audio was nearly 1 hour 50 minutes. Pat Roach, the producer of TRC, did the first cut at merging everyones’ audio and cutting out all the stutters and restarts, so a big thanks to him because I did very little after his first cut.
