Transcript
- 0:01Speaker 1: Welcome to Stuff You Should Know, a production of I
- 0:04Speaker 1: Heart Radio. Hey, and welcome to the podcast. I'm Josh Clark.
- 0:13Speaker 1: There's Charles w Chuck, Brian over there, and Jerry's not here.
- 0:17Speaker 1: But we're going to make it through somehow, uh, in
- 0:21Speaker 1: this edition of Stuff You Should Know. Um, I'm going
- 0:24Speaker 1: to call this one Chuck the Icarus Edition, because we
- 0:28Speaker 1: made it through the Sun Podcast just hanging on by
- 0:31Speaker 1: our fingernails before and through just an astounding act of hubris.
- 0:37Speaker 1: We're going to do another Sun related episode. Yeah. We
- 0:41Speaker 1: talked about a lot of this stuff in the Sun one.
- 0:44Speaker 1: Yeah we did, but I don't think we went anywhere
- 0:46Speaker 1: near into this kind of detail. So I'm feeling okay
- 0:48Speaker 1: about redoing this, doing something that that's like kind of
- 0:51Speaker 1: a re redo a little bit. Okay, are you feeling okay?
- 0:56Speaker 1: I'm feeling great. Oh good, I'm glad to hear that.
- 1:00Speaker 1: I don't know if I would say I'm feeling great,
- 1:01Speaker 1: but that's good that you are at least so. Um,
- 1:07Speaker 1: we're talking about the Sun, believe it or not, and
- 1:10Speaker 1: we're talking about a specific thing on the Sun called
- 1:12Speaker 1: solar flares, which you may have heard of, but you
- 1:15Speaker 1: may not know much about unless apparently you've already listened
- 1:18Speaker 1: to our Sun episode. But um, we'll talk a little
- 1:21Speaker 1: bit about solar flawers. But one of the things that
- 1:23Speaker 1: that I think is extraordinarily interesting about solar flowers is
- 1:26Speaker 1: they belong to a larger category called space weather. And
- 1:31Speaker 1: I am just as jazz as can be about the
- 1:33Speaker 1: idea of space weather, aren't you? Uh not as jazz
- 1:37Speaker 1: as you, I don't think, but I do think this
- 1:40Speaker 1: is this is pretty neat stuff, and I'm glad we're
- 1:42Speaker 1: we're getting a chance to make it more clear than
- 1:45Speaker 1: we did before. Yeah, yeah, yeah, there's a good that's
- 1:50Speaker 1: a good point. I'm sure we talked about this before,
- 1:52Speaker 1: but it's probably extremely confusing. So yeah, we're going to
- 1:54Speaker 1: clear all that up. So space weather, especially stuff that
- 1:58Speaker 1: comes from the Sun, come mostly from the surface or
- 2:01Speaker 1: the atmosphere of the Sun, which is extraordinarily active. It's
- 2:08Speaker 1: extraordinarily hot, so hot, chuck. Um that the surface of
- 2:11Speaker 1: the Sun is made of plasma, which a lot of
- 2:14Speaker 1: people consider the fourth state of matter. It's like a gas,
- 2:18Speaker 1: but it's a special kind of gas that um where
- 2:22Speaker 1: the particles are as jazzed about being alive as I
- 2:24Speaker 1: am about the idea of space weather. That's right. They're
- 2:27Speaker 1: supercharged and when they are moving around, they create something
- 2:32Speaker 1: called metic magnetic fields. Not the band, the thing, even
- 2:36Speaker 1: though it is a great band name and a great band. Uh,
- 2:40Speaker 1: and they are gonna you know, magnetic fields have their
- 2:45Speaker 1: own effect on all these particles and what's going on
- 2:47Speaker 1: in there. Yeah. So the the energetic electrons that have
- 2:51Speaker 1: been stripped from the atoms, creating electrons and ions which
- 2:54Speaker 1: have a charge, they create magnetic fields, and then the
- 2:57Speaker 1: magnetic fields they create have an effect on them, um
- 3:00Speaker 1: so that they tend to follow these magnetic field lines.
- 3:04Speaker 1: But the the stuff is so energetic and so hot
- 3:07Speaker 1: that the magnetic fields that develop aren't like this kind
- 3:10Speaker 1: of orderly lines that keep their distance, you know, nice
- 3:14Speaker 1: and tidy like you imagine like a magnetic field to exist.
- 3:17Speaker 1: Like these things are like roiling, curling, twisting. It's just
- 3:23Speaker 1: a big orgy of magnetism up there. That's the only
- 3:28Speaker 1: way to put it. That's it. I had no choice
- 3:30Speaker 1: but to say it like that. Yeah, and then, uh,
- 3:33Speaker 1: you know, this stuff is going on. It's called solar activity,
- 3:36Speaker 1: and it depends on when you're observing the Sun, it's
- 3:40Speaker 1: going to be more or less active. There's a there's
- 3:43Speaker 1: a cycle, it's called the solar cycle that happens about
- 3:46Speaker 1: every eleven years when the magnetic north and south pole switch.
- 3:51Speaker 1: And within that cycle, UM, there's something called a solar maximum,
- 3:55Speaker 1: which is the period kind of where the biggest show
- 3:59Speaker 1: is going on. Yeah, there's also a solar minimum, but
- 4:01Speaker 1: the solar maximum is UM. We're in solar cycle twenty
- 4:05Speaker 1: five apparently, and the solar maximum is coming up on
- 4:08Speaker 1: in two thousand. That's very appropriately UM. And so as
- 4:12Speaker 1: we're reaching the solar maximum, there's gonna be a lot
- 4:15Speaker 1: more of what people call sun spots. By people, I
- 4:19Speaker 1: mean astronomers, of course, um. And sun spots are these
- 4:23Speaker 1: kind of darkish areas on the surface of the Sun.
- 4:28Speaker 1: They can be little, tiny dots, they can be kind
- 4:29Speaker 1: of big, but they look really really small and they
- 4:32Speaker 1: look dark. UM. And the reason they look dark is
- 4:35Speaker 1: because they're relatively cool compared to the rest of the
- 4:38Speaker 1: surface that's around them. Um. But even still, they're super
- 4:43Speaker 1: duper hot and they're still pretty bright comparatively speaking. Yeah,
- 4:46Speaker 1: Like a sun spot is about degrees fahrenheit. Because we're
- 4:51Speaker 1: talking about the sun so cool is a relative term here. Uh.
- 4:55Speaker 1: And as far as bright goes, it's about that's about
- 4:57Speaker 1: ten times as bright as a full moon. So if
- 5:00Speaker 1: you go out at night in a full moon and
- 5:03Speaker 1: it kind of feels like a little cool daylight, a
- 5:05Speaker 1: sun spot is about ten times brighter than that. Right,
- 5:09Speaker 1: So you shouldn't go looking at these things. No, No,
- 5:11Speaker 1: that's a really good thing to say. Is like, we're
- 5:13Speaker 1: talking about a lot of stuff that's gonna make you
- 5:15Speaker 1: want to look at the sun. Don't do it. Just
- 5:17Speaker 1: go online and look at pictures of this stuff on
- 5:20Speaker 1: the sun or videos even we have videos thanks to
- 5:23Speaker 1: the good people at NASA, but um, the sun spots,
- 5:26Speaker 1: So it really just goes to show you how hot
- 5:28Speaker 1: and bright the surface of the Sun is. That these
- 5:30Speaker 1: things seem cool and dark by comparisons. And yeah, and
- 5:34Speaker 1: they are really really big, So the width of them
- 5:37Speaker 1: can get to be up to thirty thous miles across,
- 5:39Speaker 1: which is about the width of Neptune, which is huge,
- 5:43Speaker 1: about four times the width of Earth. Um, and still
- 5:47Speaker 1: they look super dinky compared to the Sun. And the
- 5:50Speaker 1: reason that these things are cooler, chuck, is because they're
- 5:54Speaker 1: spots of magnetism that are so strong that they keep
- 5:58Speaker 1: the heat inside the Sun from poking out right there.
- 6:02Speaker 1: That's how strong the magnetic energy is in these areas. Yeah,
- 6:06Speaker 1: and that's right. And because they're magnets, they form in
- 6:09Speaker 1: little pairs like little buddies, and they appear on the
- 6:13Speaker 1: surface of the Sun. And what we're actually looking at
- 6:15Speaker 1: if you can like go to uh NASA or whatever,
- 6:18Speaker 1: like you said, and see a picture of a sun spot,
- 6:20Speaker 1: what you're looking at is sort of like the two
- 6:22Speaker 1: ends of um. If you think about these magnetic lines there,
- 6:27Speaker 1: these magnetism it's like a filament like a rope. Just
- 6:30Speaker 1: picture them twisted up basically running beneath the sun surface.
- 6:34Speaker 1: And there are some really really cool pictures and stuff.
- 6:37Speaker 1: And then one end of this sun spot is positive,
- 6:40Speaker 1: the other end is negative, and it's they sort of
- 6:43Speaker 1: act like rings of a tree a little bit. As
- 6:47Speaker 1: far as astronomers can like observe these things. The first
- 6:51Speaker 1: sun spots of each cycle are in the midd latitudes
- 6:54Speaker 1: and then they start moving around during the cycle, so
- 6:57Speaker 1: they can kind of see where you are in the
- 7:00Speaker 1: solar cycle by where and how many of these sun
- 7:02Speaker 1: spots there are. Yeah, so the more the closer to
- 7:06Speaker 1: the solar maximum you are, the more sun spots they're
- 7:08Speaker 1: going to be, and the closer they're going to be
- 7:10Speaker 1: to the equator. So they tell a lot about where
- 7:13Speaker 1: where the Sun is in its solar cycle. Um. But
- 7:16Speaker 1: the thing is when these magnetic field lines twists and
- 7:20Speaker 1: and curve and turn, um, they actually can interact with
- 7:25Speaker 1: other magnetic field lines. And when that happens, when they cross,
- 7:30Speaker 1: kind of like the proton streams crossing in Ghostbusters. When
- 7:34Speaker 1: that happens, UM, something called the solar flare, uh happens.
- 7:39Speaker 1: It's a it's an event on the Sun, and it
- 7:41Speaker 1: is such a huge, magnificently energetic event that it actually
- 7:47Speaker 1: can affect Earth things on Earth because it's just so
- 7:51Speaker 1: massive in such a huge release and sudden release of energy.
- 7:55Speaker 1: I had a Ghostbusters ref penciled end later on if
- 7:58Speaker 1: you believe that. Oh, I can't wait to it's been
- 8:00Speaker 1: a long time, when we both have to we have
- 8:03Speaker 1: one each. Um, Yeah, it has. And it's been a
- 8:07Speaker 1: while since we listed dates by the years before since
- 8:11Speaker 1: Ghostbusters came in. Mind has a data attached to it,
- 8:13Speaker 1: and you'll just have to wait. I can't wait. What
- 8:15Speaker 1: a great episode this is shaping out to be. So
- 8:18Speaker 1: these explosions, the magnetic fields are driving these explosions. And
- 8:23Speaker 1: if you you know, if you're lay people like us,
- 8:26Speaker 1: it's you can either look at this is something that's
- 8:29Speaker 1: kind of simple to look at on its surface, or
- 8:32Speaker 1: if you really want to get into it, it's pretty
- 8:34Speaker 1: complex and not easily understood. But the simple answer is,
- 8:38Speaker 1: because we're talking about magnetic fields, is that these adjacent
- 8:42Speaker 1: fields are pointing in opposite directions and they basically wipe
- 8:46Speaker 1: each other out and that releases all this magnetic energy
- 8:50Speaker 1: and all that heat, uh, kind of everywhere that surrounds it.
- 8:54Speaker 1: It just goes spew spew, spew energy heat shooting at
- 8:58Speaker 1: you from the sun. Right, So people have figured this out.
- 9:02Speaker 1: Finally that has to do with, like um, the lines
- 9:06Speaker 1: of magnetism interacting with one another and annihilating one another.
- 9:09Speaker 1: But there's a big mystery attached to this, or there
- 9:12Speaker 1: there was for many many years, and that is that. Okay,
- 9:15Speaker 1: so we understand magnetic annihilation. But to this point, we
- 9:19Speaker 1: thought it took about ten thousand years for two opposite
- 9:24Speaker 1: magnetic fields to annihilate one another. Well, we're talking about here,
- 9:28Speaker 1: these solar flares. They they annihilate one another and release
- 9:32Speaker 1: all this energy in a matter of minutes, maybe an
- 9:35Speaker 1: hour sometimes, So that doesn't quite job. And I think
- 9:39Speaker 1: back in the fifties some scientists started proposing a type
- 9:43Speaker 1: of magnetic energy released called magnetic reconnection. And that is
- 9:47Speaker 1: where magnetic field lines are so um twisty, turney writhey
- 9:52Speaker 1: and energetic that they can actually rip a field line
- 9:56Speaker 1: or like a magnetic field line can rip a part
- 10:00Speaker 1: and then reconnect with some neighbors. When that happens, it's
- 10:04Speaker 1: called magnetic reconnection. And they think that that is the
- 10:08Speaker 1: kind of energetic release that would account for a solar flare. Yeah,
- 10:12Speaker 1: and this, you know, this can cause all kinds of problems,
- 10:15Speaker 1: um for things in space and for people on Earth
- 10:18Speaker 1: even which we'll get to that stuff in more detail
- 10:21Speaker 1: a little bit later. But the point is these things
- 10:24Speaker 1: are super hot. Uh. They burst out to the Sun's corona, which,
- 10:29Speaker 1: if you remember from our Sun Up episode, that's the
- 10:31Speaker 1: outermost atmosphere of the Sun. Rarefied gas is all over
- 10:36Speaker 1: the place out there, and it has I mean, this
- 10:40Speaker 1: is super super hot stuff. Like normally the temperature and
- 10:43Speaker 1: the corona is about you know, a few million degrees kelvin,
- 10:47Speaker 1: but inside that flare, we're talking ten to twenty million
- 10:50Speaker 1: degrees kelvin. And we always like to uh think of
- 10:55Speaker 1: things in terms of either big max or hydrogen bombs,
- 10:59Speaker 1: and in this case, it's got to be hydrogen bombs.
- 11:01Speaker 1: The amount of energy released during a solar flare is
- 11:04Speaker 1: about um it's millions of one hundred ton hydrogen bombs
- 11:09Speaker 1: all at once. Yeah, all at once. That's a really
- 11:12Speaker 1: that's a really important point too, you know, And I
- 11:15Speaker 1: feel like a real schmo for not having calculated that
- 11:18Speaker 1: in big bags calories. I know you could do calories, yeah,
- 11:24Speaker 1: but what's the calorie of a solar flare. I don't know.
- 11:27Speaker 1: I didn't look and I feel like a jackass for
- 11:30Speaker 1: not having looked. Well, they go down easy, I know
- 11:33Speaker 1: that they do. So they're big, huge releases of energy,
- 11:37Speaker 1: and they're they're releases of radiation. They release um radiation
- 11:42Speaker 1: across the electromagnetic spectrum and that includes the visible light spectrum.
- 11:49Speaker 1: So these things just turned into these enormously bright flares,
- 11:53Speaker 1: which is where the name comes from. And we've figured
- 11:56Speaker 1: out how to classify, and there's a classifying system for
- 11:59Speaker 1: solar flares. It's a lot like the Richter scale UM,
- 12:02Speaker 1: and that there's class A, B, C, M, and X.
- 12:07Speaker 1: That's not really like the Richter scale. What's like the
- 12:10Speaker 1: Richter scale is that each of those classes UH is
- 12:13Speaker 1: ten times more powerful than the previous class. Yeah, so
- 12:18Speaker 1: like an X is the highest, that is ten times
- 12:22Speaker 1: ten times in M, a hundred times of C. And
- 12:25Speaker 1: then once you get to X, uh. You know, if
- 12:28Speaker 1: they didn't go Y and Z, they just said, let's
- 12:30Speaker 1: stick with X and then let's cool. Sure, and it
- 12:33Speaker 1: sounds totally cool, and then let's start attaching numbers to
- 12:36Speaker 1: them so you can have you know, X, one, three,
- 12:39Speaker 1: four and so on. Yeah, and so you know, each
- 12:42Speaker 1: each of those letter grades has a one through nine scale,
- 12:46Speaker 1: but X is so huge the excess scale goes beyond nine.
- 12:50Speaker 1: And I think the biggest, the biggest one that they've
- 12:54Speaker 1: ever caught so far, UM that's ever been recorded. UH
- 12:59Speaker 1: burned out the set answers that were recording it, and
- 13:01Speaker 1: the censors UM were overloaded at X eight And they
- 13:06Speaker 1: did some calculations after the fact and they figured out
- 13:08Speaker 1: that they may have been an X forty five flare.
- 13:11Speaker 1: Back on November four, two thousand three. Yeah, this was
- 13:14Speaker 1: a big deal. This was it was something called the
- 13:17Speaker 1: Halloween Storms of two thousand three, which is kind of
- 13:21Speaker 1: a fun way. Uh, you know, it happened because it
- 13:24Speaker 1: was in October and near Halloween. So while the astronomers
- 13:27Speaker 1: got excited. And this one was a little bit weird
- 13:30Speaker 1: because although it was near the solar maximum, it was
- 13:35Speaker 1: two to three years after the peak, and it was
- 13:39Speaker 1: they said, NASA said it's generally a quiet period, so
- 13:42Speaker 1: they got really really excited. There were seventeen major flares
- 13:46Speaker 1: in that uh Halloween storm, and it was that's something
- 13:51Speaker 1: that is really going to get the white coats pretty
- 13:54Speaker 1: charged up. It totally is I mean an X forty
- 13:58Speaker 1: five that's just funding And I did a little bit
- 14:01Speaker 1: of of derivative calculation. Technically it would be a double
- 14:07Speaker 1: A five A five, you know. I saw weird different
- 14:11Speaker 1: numbers too, though. I saw that the center cut out
- 14:13Speaker 1: at fifteen and the estimate was X. Huh. It's really hard.
- 14:19Speaker 1: It's NASSY even had conflicting information. I think we should
- 14:22Speaker 1: point this out that you just set us up for
- 14:24Speaker 1: a c o A that I wanted to include. So
- 14:28Speaker 1: there's two things. Um, there's a lot of disagreement on
- 14:32Speaker 1: exactly what a solar flare is and the difference between
- 14:36Speaker 1: that and coronal mass ejections, which we'll talk about in
- 14:38Speaker 1: a little bit. And it's not necessarily a disagreement in astronomy, um.
- 14:43Speaker 1: It's a disagreement among people who report on stuff like
- 14:47Speaker 1: astronomy and don't fully understand what they're talking about. So
- 14:50Speaker 1: we ran into that quite a bit. So if we
- 14:52Speaker 1: get something mixed up, please forgive us. And then secondly,
- 14:56Speaker 1: when we're talking about some of these incredible um events
- 15:00Speaker 1: in physics terms, people who are in the field of
- 15:04Speaker 1: physics understand what they're talking about to one another, but
- 15:07Speaker 1: they have a great reputation of not figuring out how
- 15:11Speaker 1: to explain it to the rest of us, and so
- 15:13Speaker 1: they'll put it in different terms. And so when you're
- 15:16Speaker 1: researching this stuff, you're like, are you is this describing
- 15:19Speaker 1: a different thing than this over here or is it
- 15:22Speaker 1: just two different people describing the same thing two different
- 15:24Speaker 1: ways because they're not describing it in the true physics
- 15:28Speaker 1: way because I wouldn't understand. So we ran into that
- 15:31Speaker 1: a lot too, did you. Yeah, And it's frustrating to
- 15:34Speaker 1: literally see two different things both from NASA dot gov
- 15:38Speaker 1: on two different pages. But you know, who are we
- 15:42Speaker 1: too to call out NASA? I think we just did.
- 15:46Speaker 1: We'll call out Space Force, sure. But the point is this,
- 15:53Speaker 1: all of that really underscores the fact that our understanding
- 15:56Speaker 1: of the dynamics on the Sun are still really early
- 16:01Speaker 1: and premature, um, and we're still figuring a lot of
- 16:03Speaker 1: stuff out, including classifying the differences between solar flares and
- 16:07Speaker 1: coronal mass ejections. Yeah, and the light show and the
- 16:12Speaker 1: you know, the fund that the astronomers had in the
- 16:15Speaker 1: Halloween storms of two thousand three was immense, no matter
- 16:18Speaker 1: whether it was x X forty partied either way, they
- 16:24Speaker 1: did they surely did check. They had a little bit
- 16:26Speaker 1: of peach snops and went to tasted some half a
- 16:30Speaker 1: shot of brandy and then went to bed. That's right.
- 16:33Speaker 1: Prove us wrong, nerds, prove us wrong. I say, we
- 16:37Speaker 1: take a break and then come back and talk about
- 16:39Speaker 1: those coronal mass ejections that I teased. Okay, we'll be
- 16:43Speaker 1: right back, everybody, m all right. So I was saying
- 17:12Speaker 1: that it's difficult sometimes to discern the difference between a
- 17:15Speaker 1: solar flare, which is a huge burst of radiation across
- 17:18Speaker 1: the electromagnetic spectrum um all at once, which, by the way,
- 17:23Speaker 1: it takes just a matter of minutes eight minutes to
- 17:25Speaker 1: be exact to reach Earth because we're talking about carriers
- 17:29Speaker 1: of the electromagnetic force, which can travel at the speed
- 17:32Speaker 1: of light. So it's where I guess, eight minutes, but
- 17:36Speaker 1: at the speed of light from the Sun, right. Um.
- 17:41Speaker 1: Coronal mass ejections are something different. Even though they seem
- 17:45Speaker 1: to be associated with solar flares in a lot of cases,
- 17:49Speaker 1: they also seem to be able to kind of stand
- 17:51Speaker 1: on their own too. Either way, they're impressive in their
- 17:54Speaker 1: own right for sure. Yeah, I mean, I think if
- 17:57Speaker 1: you were talking in terms of um visual excitement, like
- 18:04Speaker 1: a solar mass I'm sorry, a coronal mass ejection is
- 18:07Speaker 1: like a full on Grateful Dead concert, whereas a solar
- 18:11Speaker 1: flair is like when John Mayer played with members of
- 18:14Speaker 1: the Grateful Dead. Oh that's mean I was gonna say
- 18:18Speaker 1: it was. It's just an Instagram video lesson of John
- 18:21Speaker 1: Mayor teaching you some Grateful Dead lick because you know well,
- 18:26Speaker 1: but sol solar flares are more magnificent than that. Um,
- 18:29Speaker 1: so man, that's mean. Sorry, Sorry, John Mayor. If you're listening.
- 18:33Speaker 1: I'm not sorry, Josh. Sorry. He uh he's a nice guy,
- 18:36Speaker 1: he apparently, uh has I've seen some stuff like of
- 18:41Speaker 1: him teaching like people how to play Grateful Dead guitar
- 18:45Speaker 1: stuff and it's really really hard what he's doing. So
- 18:49Speaker 1: my hats off, right, So with man, I feel weird.
- 18:55Speaker 1: It just apologized to John Mayer on the stuff you
- 18:59Speaker 1: should know ast about solar flares. You didn't see that coming. No,
- 19:03Speaker 1: it wasn't in my notes. So with coronal mass ejections
- 19:08Speaker 1: at least these these are not necessarily just bursts of
- 19:12Speaker 1: um of radiation like a solar flare is these they
- 19:16Speaker 1: do have some radiation attached, but they're big thing is
- 19:19Speaker 1: um particles, highly charged, super energetic particles that it shoots
- 19:25Speaker 1: like buckshot towards the Earth at incredible speeds. I mean,
- 19:30Speaker 1: they get they get accelerated very close to the speed
- 19:33Speaker 1: of light, not the speed of light, and there's a
- 19:34Speaker 1: big difference between the speed of light and close to
- 19:37Speaker 1: the speed of light. So it takes about three or
- 19:39Speaker 1: four days usually for stuff um that's shot out by
- 19:42Speaker 1: a coronal mass ejection to reach Earth. But when these
- 19:45Speaker 1: things go off on the Sun, there like you said,
- 19:49Speaker 1: they're they're rather impressive. Yeah, like if you were looking
- 19:52Speaker 1: at this stuff and uh with a telescope and high
- 19:57Speaker 1: powered telescope that is I don't I don't think you
- 19:59Speaker 1: could well could you see any of this stuff anything
- 20:02Speaker 1: you have at home? You know, I've got a pretty
- 20:04Speaker 1: good telescope, but it's for nighttime viewing only. So with
- 20:07Speaker 1: the UM, I think you can see coronal mass ejections.
- 20:10Speaker 1: I think solar flares. You're you're best with a radio
- 20:13Speaker 1: telescope or X ray telescope, but the X ray telescope
- 20:16Speaker 1: would have to be outside of Earth's magnetosphere. Do you
- 20:19Speaker 1: have a telescope, yeah, telescope. It's not a radio telescope.
- 20:24Speaker 1: No, no no, no, I just we've never talked, we've never
- 20:26Speaker 1: scoped it up in conversation, and I would be surprised
- 20:29Speaker 1: if you didn't, but I'm glad to know you do.
- 20:31Speaker 1: We do have one. Yea so flares, Like if you
- 20:34Speaker 1: were looking through an X ray or a radio telescope
- 20:37Speaker 1: at a solar flare, it'll look cool, It'll look like
- 20:39Speaker 1: a flash of light. But those coronal mass ejections are
- 20:43Speaker 1: really impressive, big eruptions. Uh, the height can be many
- 20:47Speaker 1: times the size of the Earth, shooting out into space,
- 20:50Speaker 1: like you said, and they're they're kind of like a
- 20:52Speaker 1: belch from the Sun that actually releases part of the Sun.
- 20:56Speaker 1: It's like a bubble of plasma that's just an enormous
- 21:00Speaker 1: um often billions and billions of tons uh in mass,
- 21:05Speaker 1: just coming right at the Earth, full of these incredibly
- 21:08Speaker 1: charged particles UM. And they're so big, so massive, and
- 21:13Speaker 1: the plasma that they're made of is so energetic that
- 21:15Speaker 1: they actually have their own magnetic fields like the sawn
- 21:18Speaker 1: or the Earth UM. So when they finally do come
- 21:21Speaker 1: in contact with the planet, our planet UM, weird things
- 21:26Speaker 1: start to happen because it's own magnetic field and all
- 21:29Speaker 1: of the charged particles within the plasma contact our own
- 21:33Speaker 1: magnetosphere and then also our atmosphere UM, which is almost
- 21:37Speaker 1: designed to UM to deter the worst effects of those
- 21:42Speaker 1: things coming at us from the Sun. Yeah, so our magnetosphere,
- 21:46Speaker 1: that's our little first layer of protection. That would be
- 21:49Speaker 1: like UM, although I was about to say like Wakonda's
- 21:53Speaker 1: protective shield, that may be more like the ionosphere. But
- 21:57Speaker 1: the magnetosphere is that first protect and and it's going
- 22:00Speaker 1: to kind of brush away as many of those charge particles,
- 22:04Speaker 1: these protons that are shooting out as possible, and because
- 22:07Speaker 1: of solar wind though, uh, it's it's it's got a
- 22:10Speaker 1: shape to it. The magnetosphere has like a sort of
- 22:13Speaker 1: a compressed side that faces the Sun. It's got a
- 22:16Speaker 1: little dip near the poles of the Earth where some
- 22:19Speaker 1: really magnificent stuff is going to take place, as we'll
- 22:21Speaker 1: see in a minute. And then it's got this tail
- 22:23Speaker 1: end that flows out from the back, and the Earth's
- 22:26Speaker 1: magnetic field is going to block these particles from most
- 22:29Speaker 1: of the surface. The Sun's the solar wind is going
- 22:31Speaker 1: to push them along toward that tail and then that
- 22:34Speaker 1: dip at the poles is where you're gonna see these
- 22:37Speaker 1: really brilliant auroras. Yes, but the magnetism, the magnetic energy
- 22:44Speaker 1: from the coronal mass ejection can be so energetic that
- 22:48Speaker 1: it can actually push on the sun side, the day
- 22:53Speaker 1: side of the Earth's magnetosphere it's closest to the Sun,
- 22:56Speaker 1: push on it so much that it actually contorts the
- 22:59Speaker 1: Night's the tail end that trails off into space and
- 23:03Speaker 1: presses it together so that when it comes together the
- 23:06Speaker 1: Earth's own magnetosphere um becomes energetic and quivery and then
- 23:11Speaker 1: when it goes back to its normal energy state, it
- 23:14Speaker 1: releases a bunch of energy in the form of light.
- 23:17Speaker 1: And when that happens, the auroras that tend to congregated
- 23:21Speaker 1: the polls can actually show up all over the planet basically,
- 23:25Speaker 1: even very close to the equator. Yeah, which is crazy.
- 23:28Speaker 1: And we'll talk about some of the bigger ones and
- 23:30Speaker 1: some of the surprising places they showed up. But um,
- 23:33Speaker 1: so that's a magnetosphere. I mentioned the ionosphere. That's sort
- 23:37Speaker 1: of um, I guess the secondary protection that is another
- 23:41Speaker 1: high layer of the Earth's atmosphere, and that's going to
- 23:44Speaker 1: stop all the radiation because it's giving out a tremendous
- 23:47Speaker 1: amount of radiation. And if the ionosphere wasn't doing his
- 23:50Speaker 1: job and it wasn't there, we would be in big,
- 23:53Speaker 1: big trouble. Oh yeah, we we'd be toast. I mean, like,
- 23:57Speaker 1: these are incredibly energetic, fast traveling particles close to the
- 24:02Speaker 1: speed of light um and they would just shoot right
- 24:05Speaker 1: through the tissue in our our bodies, uh and do
- 24:08Speaker 1: all sorts of damage because they would probably knock all
- 24:11Speaker 1: sorts of electrons off of our atoms that make up
- 24:14Speaker 1: our cells and our tissue and um, we would either
- 24:17Speaker 1: develop cancer of the long term or just drop dead
- 24:20Speaker 1: from a big enough dose of the stuff. So thank
- 24:22Speaker 1: goodness for the ionosphere. I mean, it saves us like
- 24:27Speaker 1: John Mayor saved the grateful dead. Just in case he's
- 24:32Speaker 1: still listening. There's like a percentage of our audience it's like, yeah, man, preach,
- 24:37Speaker 1: and there's a percentage that was like, oh my god,
- 24:39Speaker 1: I have to turn this off. And then I'd say
- 24:42Speaker 1: the vast majority are like American exactly, the guy that
- 24:47Speaker 1: dated Jen Aniston probably. Um. So you've got the magnanosphere,
- 24:54Speaker 1: you got the ionosphere, and for the most part, these
- 24:57Speaker 1: things are capable of absorbing the worst of the on
- 25:00Speaker 1: belches and flare ups and everything, um, under normal circumstances.
- 25:06Speaker 1: But even even when it is protecting life on Earth
- 25:10Speaker 1: like us animals and the plants and the plankton and
- 25:14Speaker 1: you know, um, the whales, that kind of stuff life
- 25:17Speaker 1: here on Earth. Um, there are things that we humans
- 25:21Speaker 1: have developed that can be affected by these this space weather,
- 25:26Speaker 1: by these geomagnetic storms. Yeah, I guess should we talk
- 25:30Speaker 1: about the the Carrington event one of the most exciting events.
- 25:35Speaker 1: I thought it was pretty exciting. Yes, it's pretty good. So, uh,
- 25:38Speaker 1: this is eighteen fifty nine. Um, like this kind of
- 25:41Speaker 1: thing now is pretty magnificent, But I imagine eighteen fifty
- 25:44Speaker 1: nine astronomers were just really really knocked out by something
- 25:48Speaker 1: like this. They said, zeus is beer exactly. Uh. This
- 25:53Speaker 1: is sort of late summer August September and a big
- 25:56Speaker 1: solar storm they later called the Carrington event became him
- 26:00Speaker 1: the strongest one on record. And this is named for
- 26:04Speaker 1: a man named Richard Carrington. He was an astronomer, one
- 26:08Speaker 1: of England's best at the time, and he was in
- 26:11Speaker 1: his observatory and he was hanging out and it was
- 26:14Speaker 1: a sunny day and he was working with his telescope
- 26:17Speaker 1: and he's projecting this image of the sun on a
- 26:20Speaker 1: screen and drawing. He there were cameras at the time,
- 26:24Speaker 1: but I guess the most I don't know, accurate or
- 26:28Speaker 1: efficient way to capture what he saw was to draw
- 26:31Speaker 1: this stuff that he's observing, and that's what he was
- 26:33Speaker 1: doing on September one. Yeah, and while he was drawing
- 26:38Speaker 1: the stuff, um, he saw that some of these sun
- 26:41Speaker 1: spots that he was he was um mapping, I guess,
- 26:45Speaker 1: started to grow really really bright and he got really
- 26:49Speaker 1: excited because he'd been doing this for a while and
- 26:51Speaker 1: this wasn't something he'd seen before. So he jumped up
- 26:53Speaker 1: and he ran to get a friend who was going
- 26:55Speaker 1: to witness this mistake. Yeah, he said. He was gone
- 26:58Speaker 1: for a minute tops. When he came back, he found
- 27:01Speaker 1: that these brilliant flashes of light had already started to
- 27:03Speaker 1: like weakend. Can you imagine. He was a little bummed
- 27:07Speaker 1: about this, but he and he and his buddy still
- 27:09Speaker 1: watched these flares like go, you know, get lower and
- 27:12Speaker 1: lower and then turn into pinpoints and then vanish. Um.
- 27:16Speaker 1: So what he saw he was the first person to
- 27:19Speaker 1: record a solar flare. No one had ever seen anything
- 27:22Speaker 1: like it before. And that was at eleven three am.
- 27:27Speaker 1: It was, it was done, It finished, um and then nothing.
- 27:32Speaker 1: That was it until the wee hours of the morning,
- 27:35Speaker 1: later that night, the morning of the next day, later
- 27:39Speaker 1: that night, which I always just find endlessly confusing. What
- 27:42Speaker 1: that it took that long? No that it's the next
- 27:45Speaker 1: that night is the next morning. For some reason, it
- 27:48Speaker 1: just breaks my brain every time. I realized how sad
- 27:52Speaker 1: that is to admit. Yeah, so in the wee hours,
- 27:55Speaker 1: the skies put on a light show all over the
- 27:59Speaker 1: earth redan purple auroras, very brilliant, very exciting newspapers. You
- 28:04Speaker 1: could like read the newspaper at night. They saw this
- 28:07Speaker 1: stuff in the Hawaii El Salvador and the Bahamas. They
- 28:12Speaker 1: saw the auroras in the boat that nuts. That is nuts. Uh.
- 28:17Speaker 1: There were towns neighboring towns that thought the that like
- 28:20Speaker 1: Shelbyville was on fire, Springfield thought Shelby Bill was on fire,
- 28:23Speaker 1: and vice versa. There were birds chirping, they thought because
- 28:26Speaker 1: they thought it was dawn. Uh. There was a brick
- 28:29Speaker 1: mason crew in South Carolina that got up in you know,
- 28:33Speaker 1: they were like two beers in going to work when
- 28:36Speaker 1: they realized that, hey, it's the middle of the night.
- 28:39Speaker 1: And they looked at each other and said, man, this
- 28:41Speaker 1: is a hundred and twenty five years before Ghostbusters. Oh nice,
- 28:46Speaker 1: very nice. Check. Yeah, well it seemed canned in because
- 28:50Speaker 1: I prem, yeah, well i'll tell you what, how about this.
- 28:53Speaker 1: I'm gonna give you a huge hearty surprise laugh. And
- 28:56Speaker 1: I hinted out the conversation before all right ready, And
- 28:59Speaker 1: they all looked at each other, two beers in, and
- 29:01Speaker 1: said Ghostbusters won't even come out for another hundred twenty
- 29:04Speaker 1: five years. What. Oh my god, I did not see
- 29:08Speaker 1: that coming. Dude, how long has it been since we
- 29:11Speaker 1: talked about I don't know. That's perfect and we'll just
- 29:13Speaker 1: fix that all on editing. That's great, thanks, Chuck. I
- 29:17Speaker 1: need a I need a couple of beers myself after them.
- 29:21Speaker 1: So one of the other things, um, that really went
- 29:23Speaker 1: hey wire was the telegraph system, right, because this is
- 29:26Speaker 1: eighteen fifty nine, and the telegraphs were at the they
- 29:29Speaker 1: were the leading edge, not bleeding edge. He's taught me
- 29:33Speaker 1: that that's totally wrong, the leading edge of technology of
- 29:36Speaker 1: telecommunications at the time, UM. And these telegraph lines depended
- 29:41Speaker 1: on currents being sent over wires, UM. And so those
- 29:46Speaker 1: wires were overloaded by this geomagnetic storm so much so
- 29:50Speaker 1: that sparks were shooting off of the telegraphs. UM. Operators
- 29:55Speaker 1: were getting shocked and burned. The telegraph paper was catching
- 29:59Speaker 1: on fire when was nearby. It was very much like
- 30:03Speaker 1: a movie. All this is happening all over the world
- 30:05Speaker 1: at the same time. It's just crazy. It's like very
- 30:08Speaker 1: very early morning of the next day after the Carrington event, right.
- 30:13Speaker 1: So one of the things that got me was, um,
- 30:16Speaker 1: they they unplugged the batteries to these things, the telegraphs,
- 30:22Speaker 1: and they found that the wires were still so energetic
- 30:26Speaker 1: with electricity from the geomagnetic storm that they could still
- 30:30Speaker 1: send telegraphs even though they had no power of their own.
- 30:34Speaker 1: They were they were able to send telegrams over the
- 30:37Speaker 1: telegraph line even within it's disconnected from the batteries. That's
- 30:40Speaker 1: the fact of the show to me. Oh that's amazing.
- 30:44Speaker 1: Let me that. I mean, they must have thought it
- 30:45Speaker 1: was haunted or something. I think, think like, sure, the
- 30:51Speaker 1: plug is unplugged and it's still working. They're like Zeus's
- 30:54Speaker 1: beard is crazy. There's another thing to um. Some telegraph
- 30:59Speaker 1: operator couldn't send telegraphs even though the lines were active
- 31:02Speaker 1: because the magnetism in these currents was so strong that
- 31:08Speaker 1: the armature, the thing that they tap up and down,
- 31:11Speaker 1: was like fused to the plate beneath it. It was
- 31:14Speaker 1: just the magnets. The magnetism was so strong and it
- 31:17Speaker 1: wouldn't move. Thought it was possessed. The probably left the
- 31:22Speaker 1: room screaming. They did, says is Beard. Oh we got
- 31:28Speaker 1: the third one in there. Yeah. Should we take another break? Yeah?
- 31:33Speaker 1: Oh almost so. So one other thing. Let's just wrap
- 31:35Speaker 1: the Carrington Event up real quick, Okay, so ten am.
- 31:40Speaker 1: The effects of this whole crazy event are are done.
- 31:43Speaker 1: And you know, it gets talked about. This is a
- 31:45Speaker 1: worldwide event, but it's kind of like treated as a
- 31:49Speaker 1: scientific anomaly, right people. People understand what happened and what
- 31:53Speaker 1: caused it and why it happened. Over the years as
- 31:56Speaker 1: we learned more and more about solar flares and coronal
- 31:58Speaker 1: mass ejections, but it didn't become a parent that this
- 32:02Speaker 1: Carrington event was actually a harbinger of like real, much
- 32:07Speaker 1: bigger problems that could happen to us alive on Earth
- 32:10Speaker 1: today until the seventies, and um, maybe we'll take a break, chuck,
- 32:16Speaker 1: and come back and talk about how that could be
- 32:18Speaker 1: problematic right after this great m hm. Alright, So the
- 32:47Speaker 1: world changed a lot between the Carrington event in the
- 32:51Speaker 1: mid eighteen hundreds and in the nineteen seventies when scientists
- 32:56Speaker 1: had a much bigger handle on what this kind of
- 32:58Speaker 1: thing meant. And in the nineteen seventies we were the
- 33:03Speaker 1: whole world was very dependent on electric power. You might
- 33:06Speaker 1: be surprised to learn, right, and they knew like, hey,
- 33:10Speaker 1: if we had another Carrington event today, it could be
- 33:14Speaker 1: a big deal because and we'll get to this later,
- 33:16Speaker 1: but like, we got a lot of metal on this earth,
- 33:19Speaker 1: and we use the earth to ground everything basically with
- 33:23Speaker 1: ground wires, and that creates a unique problem potentially if
- 33:28Speaker 1: we had another event like this. Yeah, the fact that
- 33:32Speaker 1: we chose to use the earth as a ground um
- 33:36Speaker 1: to where are grounding wires go from. Our electrical components
- 33:40Speaker 1: tie into a metal rod that's driven into the earth,
- 33:43Speaker 1: so that whenever excess electricity is generated by the electronics
- 33:47Speaker 1: that we use, it gets distributed through the grounding wire
- 33:50Speaker 1: to the earth where it dissipates. That makes all of
- 33:54Speaker 1: our electronics vulnerable to a geomagnetic storm, because in a
- 33:58Speaker 1: geomagnetic storm, the ground itself can become magnetized. And even
- 34:03Speaker 1: more than that, chuck, We've buried a lot of metal infrastructure,
- 34:07Speaker 1: from like pipes to um cables to all sorts of
- 34:11Speaker 1: metal stuff is snaking through the ground right now, and
- 34:15Speaker 1: when the ground becomes magnetized into geomagnetic storm it can
- 34:19Speaker 1: create it can carry really powerful currents through all the
- 34:22Speaker 1: infrastructure up through the grounds, through the grounding wires, and
- 34:25Speaker 1: into our electronic components, uh including things like power transformers
- 34:30Speaker 1: and overload them to the point where they fail catastrophically. Yeah.
- 34:34Speaker 1: And this, uh, this sort of happened in August two
- 34:40Speaker 1: there was a big, big solar flare that knocked out
- 34:44Speaker 1: our long distance phone communication across Illinois. So that was
- 34:48Speaker 1: just sort of an early example of like, hey, this
- 34:51Speaker 1: can actually have a real effect here on Earth. UM.
- 34:55Speaker 1: And that was that was a big one. It took
- 34:56Speaker 1: I think about fifteen hours to hit Earth, whereas it
- 34:59Speaker 1: usually to two to three days. UM. It also set
- 35:02Speaker 1: off these um we had. It was during Vietnam obviously,
- 35:05Speaker 1: and we had magnetic sea mines in harbors around Vietnam.
- 35:09Speaker 1: It exploded those. Yeah, So I don't know if they
- 35:12Speaker 1: were supposed to be like secretly there and if that
- 35:15Speaker 1: was kind of like oh, whoops, sorry about that, or
- 35:19Speaker 1: if they knew that they were there and and they
- 35:21Speaker 1: just went off. But either way, UM, that was a
- 35:24Speaker 1: pretty scary scene. It was, and apparently it was a
- 35:28Speaker 1: mystery for a long time until somebody finally figured out
- 35:31Speaker 1: why those sea mines all went off. They connected it
- 35:34Speaker 1: to the UM, to that coronal mass ejection, I believe. Yeah,
- 35:38Speaker 1: but you can imagine like all the damage uh that
- 35:41Speaker 1: could occur, Like even if you're just talking about the
- 35:44Speaker 1: electrical grid. If it really blew out, it wouldn't be
- 35:47Speaker 1: just like a blackout, like it would destroy parts of
- 35:51Speaker 1: our electrical grid such that it would take It's not like, hey,
- 35:54Speaker 1: let me go out and fix this over a few
- 35:56Speaker 1: hours during a snowstorm. It's it might take weeks or
- 36:00Speaker 1: months or even up to a year if we had
- 36:03Speaker 1: a big enough, uh like blast to the grid. Yeah,
- 36:07Speaker 1: because I mean it is by necessity. Our electrical grid
- 36:11Speaker 1: is interconnected. So if one part of it gets overloaded,
- 36:14Speaker 1: that can overload other parts that are connected. And if
- 36:17Speaker 1: you have a whole city without power, for let's say
- 36:21Speaker 1: Los Angeles went went out of power for a month,
- 36:24Speaker 1: what would happen? What would be the what would be
- 36:26Speaker 1: the outcome of that? You couldn't do anything? And when
- 36:29Speaker 1: you start thinking like that, you start thinking about, oh
- 36:32Speaker 1: my god, like, think about all the stuff we do
- 36:34Speaker 1: that requires electricity. Everything we do requires electricity in some
- 36:38Speaker 1: form or fashion. And so to be without electricity in
- 36:41Speaker 1: a major city or multiple major cities for even a
- 36:45Speaker 1: couple of weeks is just unthinkable. But that's that's the
- 36:49Speaker 1: level of vulnerability whereat because of the way that our
- 36:52Speaker 1: electrical components are set up because they're grounded. Yeah, and
- 36:57Speaker 1: and not just like a chain reaction and apocalyptic kind
- 37:01Speaker 1: of activity, but um, just monetary loss, like the economic
- 37:05Speaker 1: and financial damage for the city of Los Angeles to
- 37:09Speaker 1: be without power for a month would be astounding. Um.
- 37:14Speaker 1: So you know, there's stuff they could do. They could uh,
- 37:17Speaker 1: they could fit some very critical transformers with resistors and capacitors,
- 37:22Speaker 1: but these things are like hundreds of thousand dollars per transformers,
- 37:26Speaker 1: So that's just too much money. So they're not doing that. No,
- 37:31Speaker 1: they're not. And I wonder if there's going to be
- 37:33Speaker 1: like some close call that makes everybody Okay, we need
- 37:36Speaker 1: to invest this in our infrastructure, or you know, are
- 37:39Speaker 1: we going to figure out some other means of you know,
- 37:43Speaker 1: a backup system. I'm not sure that happens to like Topeka.
- 37:48Speaker 1: And then everyone says, hey, if this happened in Topeka
- 37:53Speaker 1: and they lost you know, several hundred dollars, and that's
- 37:58Speaker 1: really mean how it's gonna say? Did you think do
- 38:00Speaker 1: you think Topeka would do it? Do you think that
- 38:03Speaker 1: would convince anybody? I don't know. I'm so sorry Topeka,
- 38:06Speaker 1: but you get my point. If it happens somewhere sort
- 38:09Speaker 1: of in a smaller area than the big cities. Might say, Hey,
- 38:13Speaker 1: that means it could happen to us, the people who
- 38:15Speaker 1: really matter, right, the coastal elites would stroke their beards
- 38:21Speaker 1: and struck their tongues. Yeah so, um so yeah, there's
- 38:25Speaker 1: there doesn't seem to be a lot of initiative right
- 38:27Speaker 1: now to figure this out, and we're just kind of
- 38:31Speaker 1: sitting ducks in a weird way. It's nothing. I don't
- 38:33Speaker 1: think it's anything to lose sleepover. But it's really surprising.
- 38:36Speaker 1: Like the more I dug into this, the more I
- 38:38Speaker 1: was like, huh, this could kind of be a thing someday.
- 38:42Speaker 1: And it's not just you know, the electrical grid uh
- 38:47Speaker 1: here on Earth alone is what is all that would
- 38:50Speaker 1: be affected by that? There um, things we rely on
- 38:53Speaker 1: out in space, like satellites a bad enough to you,
- 38:57Speaker 1: a magnetic storm could affect satellites and a out of weights,
- 39:00Speaker 1: so our GPS systems would be messed up. Or if you,
- 39:04Speaker 1: um so, if you use GPS for really important stuff
- 39:08Speaker 1: like say landing an airplane, you could be in big trouble.
- 39:12Speaker 1: Um and if you're also on planes, the high frequency
- 39:16Speaker 1: radio communications they used to stay in contact with the ground,
- 39:19Speaker 1: especially when they're out over the ocean or something like that. UM,
- 39:22Speaker 1: that can be disrupted by a solar flare or a
- 39:26Speaker 1: chronal mass ejection too. Yeah, or what about a satellite
- 39:29Speaker 1: maybe that is I mean, there are thousands of satellites
- 39:32Speaker 1: up there, but and you know, if a radio satellite
- 39:34Speaker 1: went out, it would be bad, but people could live.
- 39:37Speaker 1: But what if it affected a satellite that's UM in
- 39:40Speaker 1: charge of aiding in national defense. Things could get a
- 39:44Speaker 1: little bit scary if those satellites were down or you know, spacecraft,
- 39:49Speaker 1: their spacecraft up there and they use satellites to help
- 39:52Speaker 1: orient themselves and and keep themselves safe. Uh, there's an
- 39:58Speaker 1: I S S. Although the ice supposedly is UH is
- 40:02Speaker 1: protected right yeah, oh yeah. The the big threat to
- 40:06Speaker 1: UM astronauts from coronal mass ejections and solar flares is
- 40:10Speaker 1: when they're out on spacewalks, when they're doing like labor,
- 40:14Speaker 1: say outside the I S S or something like that. UM.
- 40:17Speaker 1: Just like here on Earth, if we didn't have the
- 40:19Speaker 1: ionosphere of the magnetosphere, UM, we would be in big trouble.
- 40:23Speaker 1: Astronauts can be in big trouble. The I S s
- 40:26Speaker 1: orbits within the Earth's magnetosphere, but it's beyond the ionop
- 40:30Speaker 1: so they are a little more exposed. On the I
- 40:32Speaker 1: S S. It's shielded, so they're not nearly as exposed.
- 40:35Speaker 1: But out on a spacewalk they if it were a
- 40:37Speaker 1: really bad chronal mass ejection, they could be in a
- 40:40Speaker 1: lot of trouble. Um like Sandra her face in that
- 40:43Speaker 1: movie exactly. Uh, what is your last name? I can't remember,
- 40:47Speaker 1: sandraw Burning, Sandra Bullo, Sandra, Sandy Duncan, Sandra Bullock. Yeah,
- 40:55Speaker 1: Sandra Bernhard in that movie Space Space trit Space Craziness.
- 41:01Speaker 1: Did you like that movie Gravity? Uh? Yeah, I thought
- 41:05Speaker 1: it was pretty good if I've only seen it once. Um,
- 41:08Speaker 1: I don't I don't know if I would have cast
- 41:11Speaker 1: her necessarily, but it's fine. Or George Cleaning, I don't
- 41:15Speaker 1: think I would have cast either of him. I mean
- 41:17Speaker 1: I had some issues. I mean it was a magnificent
- 41:18Speaker 1: looking movie, but I think in the end I had
- 41:22Speaker 1: some issues with the story in the script being like
- 41:25Speaker 1: not good enough for how great of a movie it
- 41:27Speaker 1: was trumped up to be. Did Um was that the
- 41:32Speaker 1: by the guy who did The Revenant? I think so? Yeah,
- 41:36Speaker 1: So you and I went and saw The Revenant in
- 41:38Speaker 1: Hawaii Wants when we were on vacation, because what else
- 41:41Speaker 1: is there to do in Hawaii on vacation but go
- 41:43Speaker 1: see movies. And um, we saw The Revenant and this
- 41:47Speaker 1: person next to us was there by by himself, and
- 41:51Speaker 1: he was so upset um by Tom Hardy's character and
- 41:55Speaker 1: just how evil he was that this guy was like
- 41:58Speaker 1: telling him he was the dead of all. He had
- 42:00Speaker 1: his hand up at the screen and was praying against
- 42:03Speaker 1: Tom Hardy. He was really affected by Tom Hardy's character,
- 42:06Speaker 1: which made the movie like even more thrilling because we
- 42:08Speaker 1: would look at the movie and then we watch this
- 42:10Speaker 1: person reacting to the movie too, So it was something
- 42:14Speaker 1: something to see. Yeah, I saw that once as well,
- 42:17Speaker 1: and I saw it on tour with you. Either it
- 42:20Speaker 1: was either Phoenix or San Diego. I don't would have
- 42:22Speaker 1: to look at the dates, but I just remember there
- 42:24Speaker 1: being palm trees. I think it was San Diego. Maybe
- 42:26Speaker 1: when we did a show at that spooky abandoned church, man,
- 42:31Speaker 1: I'm convinced still to this day that that's the church
- 42:33Speaker 1: from the Prince of Darkness that John Carton. That was
- 42:36Speaker 1: a weird show because that was the one I know.
- 42:38Speaker 1: You remember that guy sat on the front row and
- 42:41Speaker 1: shot the whole thing with a video camera and he
- 42:44Speaker 1: looked like he was mad too, like he was documenting
- 42:46Speaker 1: evidence or something to use against us. We both were like,
- 42:49Speaker 1: I think we were so caught off guard. We didn't
- 42:51Speaker 1: know what to say. Do we call this guy and say, sir,
- 42:54Speaker 1: can you please put away your camera? So we just
- 42:56Speaker 1: soldiered on. Yeah, we were pinned down by the unrelenting
- 43:01Speaker 1: glare of the lens. And then he went back to
- 43:03Speaker 1: his apartment and showed it on TV to his roommate,
- 43:07Speaker 1: who was the Tom Hardy guy, right, and that guy
- 43:10Speaker 1: was like, these guys are the devil. I'm praying against them.
- 43:14Speaker 1: Oh man uh alright, so yes, back to the show. Yeah,
- 43:20Speaker 1: where are we? Oh, here's the deal. We're talking about
- 43:23Speaker 1: astronauts and satellite operations and GPS. This isn't stuff that
- 43:27Speaker 1: we have just um said, well, this probably could happen
- 43:31Speaker 1: a lot of it is, but um, this actually has happened. Um.
- 43:35Speaker 1: We'd mentioned the thing in Illinois with the phone systems
- 43:38Speaker 1: and then in um the two thousand three that c
- 43:41Speaker 1: m E that did disrupt satellites and that did disrupt
- 43:45Speaker 1: high frequency radio communications that aviation relies on, and that
- 43:49Speaker 1: did blackout a city in Sweden. Mm hmm, mammo. Everyone
- 43:55Speaker 1: says no, not mammo, yeah, mamo everybody. So this the
- 44:00Speaker 1: kind of thing can happen. It does happen, it's just
- 44:02Speaker 1: never happened on such a massive scale. UM. They figured
- 44:05Speaker 1: out from looking at Arctic ice cores, apparently highly energetic
- 44:10Speaker 1: particles leave um remnants, not revenants, remnants in nitrates frozen
- 44:17Speaker 1: in the ice and at the polls and UM. By
- 44:20Speaker 1: examining these cores, they can see how bad or how
- 44:23Speaker 1: often or how many solar flares of hit Earth in
- 44:25Speaker 1: the past. And they figured out that the Carrington event
- 44:27Speaker 1: is like a five hundred years solar flare, and it
- 44:30Speaker 1: happened about a hundred and seventy years ago. Hopefully we're
- 44:33Speaker 1: in the clear. The key is we're still figuring out
- 44:36Speaker 1: the dynamics of the Sun and solar activity, so we're
- 44:39Speaker 1: not exactly certain that maybe we're not due for a
- 44:41Speaker 1: thousand years solar flare. UM. We're just starting to figure
- 44:45Speaker 1: this out, but we are figuring it out. That's step one.
- 44:49Speaker 1: And we also actually have space weather forecasters here on
- 44:53Speaker 1: Earth at Noah and at the National Weather Service, there
- 44:56Speaker 1: are people whose job it is subtract solar activity and
- 45:00Speaker 1: predict things like coronal mass ejections and solar flares so
- 45:03Speaker 1: that people can, like like utility companies, can maybe take
- 45:08Speaker 1: um steps to mitigate the worst effects. Eventually. I think
- 45:12Speaker 1: right now we've got like eight to ten minute heads up,
- 45:14Speaker 1: so that's not enough. But as we get to understand
- 45:16Speaker 1: it a little more, we'll have more warning time. And
- 45:19Speaker 1: you know, astronauts can plan their spacewalks when they're out
- 45:22Speaker 1: doing stuff like building future space colonies. This is all
- 45:25Speaker 1: going to come into play for that too. Yeah, So
- 45:28Speaker 1: hopefully they can get that up to at least over
- 45:31Speaker 1: an hour. That would help. Sure. So again, it's nothing
- 45:34Speaker 1: to lose sleepover. That's not the point of this episode.
- 45:36Speaker 1: It's more just kind of like ge whiz, this is
- 45:39Speaker 1: this is amazing by Zeus Beard. I've never heard of
- 45:41Speaker 1: anything like the old fourth reference. Yeahs, surprising fourth one
- 45:46Speaker 1: did not see that coming. Did you got anything else?
- 45:50Speaker 1: I got nothing else? All right, everybody chucks that he's
- 45:53Speaker 1: got nothing else. So that's it for this episode, which
- 45:55Speaker 1: means it's time for listener mao. Well, let me see here.
- 46:01Speaker 1: I've actually got quite a few today, which is uh
- 46:04Speaker 1: an abundance. We've been getting more than usual, I haven't. Yeah,
- 46:07Speaker 1: we've been getting good ones. All right, I'll choose this one.
- 46:10Speaker 1: I'm gonna call it Rush Girl. Hey guys, I've been
- 46:14Speaker 1: a long time listener, but you have never But I've
- 46:16Speaker 1: never had a reason to write until your recent Fort
- 46:18Speaker 1: Knox episode. In it you refer to the joke you
- 46:21Speaker 1: had made about women not liking the Three Stooges. By
- 46:24Speaker 1: the way, I got a little grief for that and
- 46:26Speaker 1: also support for that. Weirdly, Chuck made the comment that
- 46:29Speaker 1: it wasn't like he had something had said something true,
- 46:33Speaker 1: but they're like there being no women Rush fans. I
- 46:37Speaker 1: immediately laugh because my future and mother in law is
- 46:39Speaker 1: the biggest Rush fan. I love this lady. She and
- 46:43Speaker 1: my fiance have a bond over this band. In contrast,
- 46:46Speaker 1: I thought the band was made up just for the
- 46:49Speaker 1: movie I Love You Man. Wow. Yeah, Megan did not
- 46:55Speaker 1: know Rush was a real band. She thought that was
- 46:57Speaker 1: a fake band in a movie. Megan, you have a
- 47:00Speaker 1: whole world ready to open up to you. Yes, you do.
- 47:03Speaker 1: I guess that they fit the trope According to my fiance,
- 47:07Speaker 1: they call female rush fans getty corns, which sounds made up,
- 47:12Speaker 1: but he swears it's true getty corns. I don't get that,
- 47:16Speaker 1: but like a unicorn maybe, oh yeah, exactly, or or
- 47:20Speaker 1: it could be candy corn. No, no, I'm sure it's
- 47:23Speaker 1: like the Getty Getty Lee unicorn mash up. I like that.
- 47:27Speaker 1: I didn't get that until just now, so thank you.
- 47:30Speaker 1: At any rate, I can recognize the joke, and I'm
- 47:33Speaker 1: not coming after you for that. I just found it
- 47:34Speaker 1: funny that all the stereotypical male bands you could have picked,
- 47:37Speaker 1: you chose my mother in law's favorite. Thanks for all
- 47:40Speaker 1: you do. Your podcast has gone a long way toward
- 47:42Speaker 1: helping me distress after a day of teaching during COVID.
- 47:46Speaker 1: And that is from Megan Power and Megan, thank you,
- 47:50Speaker 1: and big ups to your mother in law for being
- 47:52Speaker 1: a getty corn. Yeah, not to be confused with candy corn. Well,
- 47:58Speaker 1: if you want to be like Megan and let us
- 47:59Speaker 1: know how we just totally blew your mind somehow or other.
- 48:03Speaker 1: We love hearing that stuff. You can put it in
