Speaker 1: Warning.
0:00
Speaker 2: The following podcast contains an entertaining look at astronomy, physics,
0:04
Speaker 2: and space news throughout the known universe. Listeners have been
0:07
Speaker 2: known to learn about astronomical phenomenon, the scientific method, and
0:10
Speaker 2: expanded vocabulary to include terms like quasar, asterism and uranus. Listen,
0:15
Speaker 2: that's your own risk.
0:16
Speaker 1: Go ahead.
0:22
Speaker 3: When made of stars, made them stars, made sizes. When
0:29
Speaker 3: made of stars, you could be from high they would
0:36
Speaker 3: New Mexicomus. Where are.
0:41
Speaker 4: Stars? When we are made of stars?
0:57
Speaker 5: I'm Wes Carrol, joined by my good friend, doctor Sewn Cruise,
1:00
Speaker 5: an executive director of Columbus State University's Coca Cola Space
1:04
Speaker 5: Sigence Center.
1:05
Speaker 1: Hey Sean, Hey Wes.
1:06
Speaker 3: It's good to be here today.
1:08
Speaker 5: Eventually we get there. Eventually. Sometimes we had some technical difficulties,
1:13
Speaker 5: but we are here and it just feels like a
1:15
Speaker 5: technical difficulties kind of day, doesn't it. Sometimes it just
1:18
Speaker 5: it's just in the air and there's nothing you can
1:21
Speaker 5: really do about it.
1:21
Speaker 3: It's just, you know, we're not the only ones that
1:24
Speaker 3: have technical difficulties. I mean, you could talk about you know,
1:28
Speaker 3: like a moon rocket that might be having some technical
1:30
Speaker 3: difficulties at the moment, for instance.
1:32
Speaker 1: For instance, that's a good you like.
1:34
Speaker 3: Say, if you had a space podcast and you wanted
1:38
Speaker 3: to talk about, like, you know, rockets that go to
1:40
Speaker 3: the Moon, you can say, well, yeah, you know, we're
1:43
Speaker 3: not alone and having technical difficulties because there's this very
1:47
Speaker 3: large moon rocket that they're looking for leaks of hydrogen
1:50
Speaker 3: on right now, and.
1:51
Speaker 5: Yes, waiting for our next opportunity to launch all of
1:55
Speaker 5: those things. It happens, That's right. It happened sometimes.
2:00
Speaker 1: But now we're go. We are at that story in.
2:03
Speaker 3: I mean maybe people already knew that so, but we
2:06
Speaker 3: just wedged it in. It wasn't on the list.
2:07
Speaker 1: That's true.
2:08
Speaker 5: We talked about it last week, and we'll continue to
2:11
Speaker 5: do follow ups with it as we get closer and closer.
2:13
Speaker 5: I mean, I could point out the fact that like
2:16
Speaker 5: seventy five percent at least of my household is sick.
2:21
Speaker 5: The three people who don't work from home are currently
2:24
Speaker 5: all at home, and the one who does work from
2:27
Speaker 5: home is isolated in his studio, so that we can
2:30
Speaker 5: do this. So I think about this, the fact that
2:35
Speaker 5: these astronauts are at quarantine waiting, still waiting to go
2:39
Speaker 5: next month. I guess they just stay in quarantine the
2:41
Speaker 5: whole time.
2:41
Speaker 3: They actually released them. They're going to re quarantine them
2:44
Speaker 3: as what they're doing. So they have actually gotten to
2:46
Speaker 3: go home, which is good.
2:47
Speaker 1: Yeah, that's a.
2:48
Speaker 3: Good thing, right, Yeah, So but you know, one can
2:52
Speaker 3: imagine how much pleasure they'll feel when they have to
2:55
Speaker 3: go back in the quarantine, you know, because they quarantine
2:58
Speaker 3: them the first time anyway, So well, you know this
3:01
Speaker 3: is the way it goes. Look, if you're gonna live
3:03
Speaker 3: the astronaut life, you have to take the twists and turns,
3:07
Speaker 3: the ups and downs, the quarantine and then second quarantine
3:12
Speaker 3: and maybe.
3:12
Speaker 1: Even a third quarantine if necessary.
3:14
Speaker 5: And you have to also know that you're you're gonna
3:17
Speaker 5: eat be eating freeze dried meals no matter whether you're
3:20
Speaker 5: stuck or not.
3:21
Speaker 1: That's just part of the way the meals work.
3:24
Speaker 3: So you're telling me they don't get pilet mignon and
3:28
Speaker 3: pasta carbon ea every night.
3:30
Speaker 5: I mean, those space walks, they're not to go outside
3:32
Speaker 5: and grill like I would think that you as long
3:34
Speaker 5: as you're outdoors, you know.
3:36
Speaker 3: Yeah, I mean that's right to grill a safe distance
3:40
Speaker 3: away from the space station.
3:42
Speaker 1: It's like at an apartment complex.
3:44
Speaker 5: You can't do it on the balcony, but you can
3:46
Speaker 5: get you know, within so many feet of the apartment,
3:48
Speaker 5: and that's perfectly fine. Well, they're not the only people
3:52
Speaker 5: that are waiting to go to space because they're going
3:56
Speaker 5: a little you know, a better, longer trip, better trip arguably.
4:00
Speaker 5: But I would think that some of the Crew twelve
4:04
Speaker 5: people are just ready to get on with their mission.
4:07
Speaker 5: And obviously Crew eleven came home with a medical emergency.
4:13
Speaker 1: Do they ever use the word emergency?
4:14
Speaker 5: I know at one point they kind of called an emergency,
4:16
Speaker 5: but bringing them home, I would think it's safe to
4:18
Speaker 5: say an emergency.
4:19
Speaker 1: But anyway that brought I.
4:21
Speaker 3: Think they were trying to purposely avoid using the word
4:24
Speaker 3: emergency and called it things like I can't remember exact word,
4:29
Speaker 3: but things like a medical situation or circumstance or these
4:32
Speaker 3: kinds of words that were just a little less aggressive,
4:36
Speaker 3: just a little bit less maybe emotionally charged wording for
4:40
Speaker 3: that situation.
4:42
Speaker 1: Crew eleven came home.
4:44
Speaker 5: The current crew of the International Space Station has been
4:48
Speaker 5: enjoying lots of extra space, probably not enjoying the extra
4:52
Speaker 5: chores they have to do to keep things running up there. However,
4:57
Speaker 5: some help is on the way. As Crew twelve getting
4:59
Speaker 5: ready possible launching Friday.
5:02
Speaker 3: What do you mean it's my turn to clean the
5:04
Speaker 3: space toilet again? What? Well, there's only three of us.
5:08
Speaker 3: Oh where are those other people? Oh? Yeah, well if
5:11
Speaker 3: they're setting evacuation.
5:13
Speaker 1: That's right.
5:13
Speaker 5: If there's three of you, if you just clean it
5:15
Speaker 5: each time, then nobody has to do the big clean, right, Like.
5:21
Speaker 3: I hope that they have this philosophy that they share
5:23
Speaker 3: among each other. I really hope that they're doing that.
5:26
Speaker 1: So do they have their own separate attachment?
5:31
Speaker 3: I would hope.
5:32
Speaker 4: Yeah, Yeah, I'm saying so.
5:34
Speaker 3: I mean, I don't think it's the one size fits
5:36
Speaker 3: all world, right, so everybody has Yeah, so everybody has
5:38
Speaker 3: their own attachment and they just have to clean it.
5:41
Speaker 1: So yeah, it kind of is that, I guess.
5:43
Speaker 3: I think, Yeah, the attachment points might vary for certain physiologies,
5:48
Speaker 3: don't you know.
5:49
Speaker 5: We have been doing this in some form for almost
5:52
Speaker 5: twenty years, the two of us, And this is the
5:55
Speaker 5: first time I think I've ever asked you any bathroom stuff.
5:59
Speaker 5: I know it's the god for when field trips come
6:01
Speaker 5: in and anybody's there in the building. You probably answer
6:04
Speaker 5: toilet questions more than anything else, I'm assuming other than
6:08
Speaker 5: when there's like a big event and people want to
6:10
Speaker 5: know about, you know, an eclipse or something, but you
6:12
Speaker 5: probably get more toilet question anything else.
6:14
Speaker 1: I think that's my first toilet question i've made.
6:17
Speaker 3: I can't remember a lot of them. I think we've
6:19
Speaker 3: maybe addressed certain, you know, potty issues over the years,
6:23
Speaker 3: but yeah, but maybe not like a direct like how
6:25
Speaker 3: does this attach kind of question. I will tell you
6:29
Speaker 3: that there was a certain Apollo astronaut who was here
6:33
Speaker 3: who talked about one of his colleague Apollo astronauts just
6:37
Speaker 3: kind of drifting through the command module tethered to the
6:41
Speaker 3: very device that you're talking about, just hanging off of
6:44
Speaker 3: his posterior, just free floating through space with that taped
6:49
Speaker 3: in a certain location. So, yeah, that was a pretty
6:52
Speaker 3: entertaining story. I'm gonna leave out the exact wording and
6:55
Speaker 3: details that that certain Apollo astronaut used, but advice to
7:00
Speaker 3: say it was colorful.
7:02
Speaker 5: I have to ask was he actively using it while
7:06
Speaker 5: he was floating through Is that what he was?
7:08
Speaker 3: I don't know if he was, you know, this was
7:10
Speaker 3: like if he was in the the batter's box in
7:14
Speaker 3: the on deck circle.
7:15
Speaker 1: I'm not really sure, all right? I mean was true,
7:19
Speaker 1: I have a prep for a colonoscopy.
7:21
Speaker 5: I could think where that would come in andy, Uh,
7:23
Speaker 5: just walking around through the house.
7:25
Speaker 3: I don't think it was an after use. It was
7:26
Speaker 3: either like a before use or a durring.
7:31
Speaker 5: There is no after use when it's a colonoscopy prep.
7:34
Speaker 5: That's what I'm saying.
7:36
Speaker 1: It's pretty much it's pretty much.
7:38
Speaker 5: Use and then the colonoscopy there's not really a you
7:43
Speaker 5: know anyway.
7:45
Speaker 3: The first time listening to this podcast, friends, just know
7:48
Speaker 3: that this is not this is not our approach every week.
7:53
Speaker 1: That's true.
7:53
Speaker 5: We have real stories to get to and we're about to.
7:56
Speaker 5: But I just I just want to say this. Nobody
7:58
Speaker 5: wants to deal with the prep, but you gotta do it.
8:01
Speaker 5: Forty five. That's the age, guys, that's the age gals.
8:04
Speaker 1: You gotta do it, all right.
8:06
Speaker 5: So yeah, let's talk about Crew twelve because they are
8:11
Speaker 5: getting ready to launch maybe the end of the week,
8:14
Speaker 5: just in time for Valentine's four.
8:16
Speaker 3: More people are getting ready to go up there to
8:18
Speaker 3: help with these various chores that we were discussing, so
8:21
Speaker 3: they'll be able to spread that around again a little bit.
8:24
Speaker 3: Who are these four people, let's talk about that. So
8:27
Speaker 3: the crew twelve astronauts from NASA, it's Jessic Kamir and
8:31
Speaker 3: Jack Hathaway. From the European Space Agency, it's Sophie Adno
8:35
Speaker 3: and from ros Cosmos Andre Fidi Aev. And that is
8:40
Speaker 3: your upcoming share the chores Crew twelve heading for the
8:44
Speaker 3: International Space Station. List of astronauts, cosmonauts and isonauts that
8:49
Speaker 3: are heading up that direction. So they're getting ready to
8:53
Speaker 3: launch from Pad forty at the Cape Canaveral Space Force Station.
8:58
Speaker 3: It's not going to happen earlier than Friday of the
9:01
Speaker 3: week that we're recording this, because let's see, the real headline,
9:04
Speaker 3: your friends, is that they meant to launch this thing
9:06
Speaker 3: earlier this week, in fact, even on Wednesday. But they've
9:10
Speaker 3: been running into weather issues. And you might say, oh, yeah,
9:13
Speaker 3: the weather in the US has been a bit tricky lately.
9:14
Speaker 3: Well that's not the only place, because the real weather
9:19
Speaker 3: issues that they're having a hang up are on the
9:22
Speaker 3: emergency landing locations throughout Europe and across the Atlantic Ocean.
9:27
Speaker 3: So whether in those locations has been not as good
9:30
Speaker 3: as it needs to be to be able to launch
9:33
Speaker 3: the mission safely. So that launch for the next crew
9:36
Speaker 3: rotation mission of International Space Station has to wait to
9:39
Speaker 3: know earlier than Friday, So at Friday at the earliest,
9:43
Speaker 3: maybe even later than that. But NASA and SpaceX leadership
9:47
Speaker 3: have determined the weather along the flight path unacceptable in
9:52
Speaker 3: case of an emergency landing, so they're bumping it off.
9:55
Speaker 3: To go to Steve Stitch, who is the NASA Commercial
9:59
Speaker 3: Crew Program Manager, quote, we could see high winds along
10:03
Speaker 3: a lot of that track, up to twenty four to
10:06
Speaker 3: twenty eight knots, especially in what we would consider our
10:10
Speaker 3: higher risk areas, the staging area, said Steve Stitch. There's
10:14
Speaker 3: a low pressure system that's kind of moving in and
10:17
Speaker 3: setting over that staging area, and it's driving those winds up,
10:22
Speaker 3: and we can really see the models agreeing over the
10:24
Speaker 3: last twenty four hours. Continuing to quote Steve Stitch, quote,
10:29
Speaker 3: the good news is we have good opportunities for the
10:32
Speaker 3: remainder of the week, and so we'll go ahead and
10:34
Speaker 3: launch when we're ready we have favorable weather, when we're
10:41
Speaker 3: good and ready, and when we have favorable weather, so
10:43
Speaker 3: says Steve Stitch, Commercial Crew Program Manager and the person
10:47
Speaker 3: overseeing the launch of Crew twelve for SpaceX and NASA.
10:52
Speaker 5: Now, I just want to say this because I love
10:56
Speaker 5: my bride. I know you love yours very much as well.
11:00
Speaker 1: We are happily married, both of us to our brides.
11:07
Speaker 5: And I just I'll just say that having Valentine's Day
11:12
Speaker 5: on a Saturday is a giant pain.
11:16
Speaker 1: So I'm looking at it.
11:17
Speaker 5: Not only are they getting to go to Space, They're
11:19
Speaker 5: they're getting to avoid so many people out on Valentine's
11:26
Speaker 5: So I'm jealous for two reasons. I'm just saying that.
11:30
Speaker 5: I mean, I mean, I love my wife. I would happily,
11:35
Speaker 5: you know, I'd walk to the moon for her.
11:36
Speaker 1: I would do that.
11:37
Speaker 5: But you know the idea of going out for a
11:41
Speaker 5: meal on Saturday Valentine's Day does not sound appealing to me.
11:45
Speaker 3: Is that like the ultimate hall pass? I think so
11:49
Speaker 3: like from Valentine's Day, like, oh I forgot your card.
11:51
Speaker 3: Oh it's because I went to Space on the thirteenth,
11:56
Speaker 3: to the moon Alice bang zoom. I mean because I
12:00
Speaker 3: don't think it works, because then it's like, well you
12:01
Speaker 3: should have thought of that, look at you going off
12:06
Speaker 3: with going off with your part. But you know, I
12:08
Speaker 3: thought we were gonna watch on the eleventh, going off
12:10
Speaker 3: here up to the thirteenth.
12:11
Speaker 1: Off with your friends.
12:13
Speaker 3: Yeah, hang around in orbit.
12:16
Speaker 1: That's right, just goofing off, I get it.
12:19
Speaker 3: Just keep floating out there.
12:21
Speaker 5: So they're set to go on Friday the thirteenth. We
12:24
Speaker 5: got any worries about that, any concerns there's a.
12:27
Speaker 3: Thing there too. I'm personally gonna just avoid the triska decophobia,
12:33
Speaker 3: you know, angle, but you just never know really, so yeah.
12:37
Speaker 5: I'm not even a little stitious, but that still makes
12:39
Speaker 5: me a little weary, so you know it.
12:42
Speaker 3: Yeah, thirteen has not been a great number for NASA.
12:45
Speaker 5: No, well, let's about five for a number as NASA
12:52
Speaker 5: ready to use AXIOUM Space fifth private mission to the
12:56
Speaker 5: Space station. And again this is not the one with
12:59
Speaker 5: Tom Cruise, right.
13:00
Speaker 3: Yeah, I think Tom is out.
13:03
Speaker 1: I think that's officially done.
13:05
Speaker 5: But it does feel like, since it was talked about
13:08
Speaker 5: years ago, we should continue to say, well, when is
13:11
Speaker 5: Tom going up there?
13:12
Speaker 3: When is Tom going? And he wrote Tom wants to
13:14
Speaker 3: go to space.
13:15
Speaker 5: I would want to go about Tom. I mean, if
13:17
Speaker 5: you get to start sprinting, he could probably get most
13:19
Speaker 5: of the way there on his feet.
13:22
Speaker 3: I bet when Tom's doing some of his workouts. He's thinking, now,
13:24
Speaker 3: this would be really good for when I go to space.
13:26
Speaker 3: Oh wait, that plans on hold anyway. Well be that
13:31
Speaker 3: as it may. Axiom is going back to space. So
13:33
Speaker 3: the ax five mission the fifth private mission to the
13:38
Speaker 3: space station, taking what we would call commercial astronauts because
13:44
Speaker 3: they're astronauts. They're actually going up and doing work on
13:47
Speaker 3: the International Space Station. You can't call him not astronauts,
13:52
Speaker 3: spaceflight participant. It's a little different than those people just
13:56
Speaker 3: go up for six minutes in a joy ride taking snowfield.
14:00
Speaker 3: I'm gonna still call them. They need some kind of designation.
14:03
Speaker 1: Yeah, that's true.
14:05
Speaker 3: But these people will actually be doing work aboard the
14:08
Speaker 3: International Space Station, including experiments which I think make me,
14:12
Speaker 3: may make some people nervous anyway, but that's okay, it
14:14
Speaker 3: doesn't matter. So NASA and Space Axiom Space have signed
14:18
Speaker 3: an order for the fifth private astronaut mission to the
14:21
Speaker 3: International Space Station. This according to NASA dot Gov Axiom.
14:25
Speaker 3: The Axiom mission is targeted no earlier than January twenty
14:31
Speaker 3: twenty seven, so it's not just around the corner. It's
14:35
Speaker 3: a little ways off, but it'll launch from Kennedy Space
14:38
Speaker 3: Center in Florida. And according to Jaredisigman, we like quoting Jaredisigman.
14:43
Speaker 3: Why because he's finally the NASA administrator, That's why, all right? So,
14:46
Speaker 3: Jared Eisenwan says this quote, the award of our fifth
14:49
Speaker 3: private astronaut mission shows that commercial space is not a
14:54
Speaker 3: distant promise but a present reality. Good quote from Jared.
14:59
Speaker 3: I like that one. He goes on to say, Jaredisenwind quote.
15:02
Speaker 3: By expanding access and sharpening competition in low Earth orbit,
15:06
Speaker 3: these missions are building the capabilities NASA will rely on
15:09
Speaker 3: as we move out to the Moon, Mars and beyond.
15:12
Speaker 3: We look forward to building upon those capabilities with many
15:17
Speaker 3: private astronaut missions to come. Unquote, so says to Jared
15:22
Speaker 3: in his new role as administrator of NASA. So Axium
15:27
Speaker 3: five mission is expected to spend about fourteen days aboard
15:30
Speaker 3: the space station, and again a specific launch date will
15:33
Speaker 3: depend on overall spacecraft traffic. Now there's traffic up there.
15:37
Speaker 3: Now you gotta worry about the traffic at the space station.
15:41
Speaker 3: So many ships, so many all right, So specific launch
15:44
Speaker 3: date will depend on the overall traffic at the overall
15:46
Speaker 3: outpost and other planning considerations, possibly like the weather or
15:51
Speaker 3: stuck hydrogen valves, whatever those things may be. So there
15:54
Speaker 3: you go. That's the latest on the AX five mission
15:57
Speaker 3: from accidom.
15:58
Speaker 5: More Made of Stars right after this, further proving that
16:22
Speaker 5: we are in fact in a space race for sure
16:26
Speaker 5: when it comes to the Moon. And for anybody who
16:28
Speaker 5: thinks we got to slow things down, we need to
16:31
Speaker 5: slow down. Why are we in such a rush to
16:33
Speaker 5: get back to the moon. China's now a step closer.
16:37
Speaker 3: Yeah, the serious story from space news dot com China
16:40
Speaker 3: took a step closer to their moon aspirations putting humans
16:44
Speaker 3: on the Moon from China. So headline from space news
16:48
Speaker 3: dot com say is this China tests crewed spacecraft will
16:51
Speaker 3: abort and rocket recovery in major lunar milestone. So China
16:57
Speaker 3: took the step forward and it's lunaric human spaceflight programs
17:01
Speaker 3: late Tuesday with a successful in flight abort and rocket
17:06
Speaker 3: recovery tests. All right, So I'm just kind of reading
17:10
Speaker 3: you some of the wording from space news dot com.
17:13
Speaker 3: But really what they're doing is that they're doing basically
17:15
Speaker 3: the same thing that we did with our Orion spacecraft
17:19
Speaker 3: back in twenty nineteen. It's making sure that it as
17:23
Speaker 3: the rocket lifts off the launch pad with humans aboard
17:27
Speaker 3: the top of it in their spacecraft, which is actually
17:30
Speaker 3: a very small piece of a moon rocket, that you
17:33
Speaker 3: can separate that capsule and get those people out away
17:38
Speaker 3: from that giant rocket if something begins to go wrong
17:42
Speaker 3: with the giant rocket. And the way it works for
17:45
Speaker 3: an Orion spacecraft is above the actual Orion capsule itself,
17:51
Speaker 3: there's a large tower. That large tower looks a bit
17:54
Speaker 3: like a cell phone tower or some kind of a
17:56
Speaker 3: gantry sticking straight up, but if you look at it carefully,
17:59
Speaker 3: you'll notice it's got some little rocket engines are around
18:02
Speaker 3: the outside of it, and those rocket engines are designed
18:06
Speaker 3: that if there is some reason that the big rocket
18:10
Speaker 3: has to be aborted, that they can fire those rockets
18:13
Speaker 3: on the on the gantry post portion above the capsule,
18:18
Speaker 3: and that that tower will remove the capsule out away
18:21
Speaker 3: from the big rocket, carry it very rapidly somewhere else
18:25
Speaker 3: to safety, while the giant rocket could potentially be exploding
18:29
Speaker 3: behind them. So again that's you don't want to have
18:33
Speaker 3: that happen because there's a lot of g force involved.
18:38
Speaker 3: It's like it's like in your car. You don't want
18:40
Speaker 3: to have the air bags go off, because those air
18:42
Speaker 3: bags are gonna snap so fast that they could cause
18:45
Speaker 3: injuries to your hands, your face, your upper chest. But
18:49
Speaker 3: those injuries, in comparison to the wreck you're about to
18:52
Speaker 3: have in your car, might be the acceptable choice. Well,
18:56
Speaker 3: that's the same thing with this little tower that sits
18:59
Speaker 3: on top of these rockets. Yes, you would probably suffer
19:02
Speaker 3: some level of discomfort to injury based on having to
19:07
Speaker 3: remove your capsule from the rocket in a very rapid manner,
19:11
Speaker 3: but you have a good a better chance, shall we say,
19:14
Speaker 3: of surviving the whole event and just getting out in
19:17
Speaker 3: a way. So again we tested that for our lunar rocket,
19:20
Speaker 3: the space launch system with its Orion capsule back in
19:23
Speaker 3: twenty nineteen. China has now tested theirs on February eleventh,
19:29
Speaker 3: So now the Long March ten rocket and their meng
19:35
Speaker 3: Jiao spacecraft have gone through that same test. It was successful.
19:40
Speaker 3: The meng Jiao descended by assisted into the sea by
19:44
Speaker 3: its parachutes and all of that happened successfully, and again
19:49
Speaker 3: no people on board. It was just a test of
19:51
Speaker 3: the system. But then the rocket, the Long March ten itself,
19:55
Speaker 3: flew out to its recovery point that was also successful.
20:00
Speaker 3: Instruation was a crucial next step in China's plans to
20:03
Speaker 3: attempt to land astronauts on the Moon by twenty thirty. So,
20:08
Speaker 3: as Wes said at the beginning of the story, it
20:10
Speaker 3: is a race. They're setting dates. Their dates are a
20:14
Speaker 3: little bit later than ours, but we're also having delays.
20:17
Speaker 3: So yeah, it's really an interesting time. It's a brand
20:21
Speaker 3: new moon race, and the outcome is still yet to
20:24
Speaker 3: be determined.
20:26
Speaker 5: All right, So for a long time now we have
20:30
Speaker 5: thought basically, middle of the Milky Way there's a supermassive
20:34
Speaker 5: black hole. Now some science says maybe not so fast,
20:40
Speaker 5: it could be something else.
20:42
Speaker 3: So think about this as a paradigm shift. Like you
20:49
Speaker 3: have bands like news writing songs called super massive black hole.
20:53
Speaker 3: Why do you have that, Well, because we know that
20:56
Speaker 3: there are such things, and we've taught generations of students. Now, hey,
21:01
Speaker 3: you know what's at the middle of almost every galaxy
21:02
Speaker 3: a super massive black hole. They're different than your garden
21:07
Speaker 3: variety black hole because the garden variety black hole has
21:10
Speaker 3: a mass of you know, maybe eight to ten to
21:14
Speaker 3: twenty times the mass of our sun. Well, these are
21:20
Speaker 3: million solar mass black holes that we have long talked about,
21:25
Speaker 3: and the location at the center of our galaxy is
21:29
Speaker 3: something called Sagittarius A. That's because in the direction of
21:33
Speaker 3: the constellation of Sagittarius the very first radio source ever discovered.
21:38
Speaker 3: Hence the A was long believed to be a super
21:42
Speaker 3: massive black hole generating radio waves. Well, it's interesting when
21:48
Speaker 3: science comes up with just a whole different, out of
21:51
Speaker 3: the box perspective that says, you know, maybe these things
21:56
Speaker 3: that we've thought existed all this time, maybe they don't
22:00
Speaker 3: exist at all. Maybe there are other some other form
22:05
Speaker 3: of exotic matter, not a black hole, but a giant
22:11
Speaker 3: lump of dark matter. Now, without going into depth on
22:18
Speaker 3: particle physics, there are kinds of dark matter that have
22:24
Speaker 3: been postulated that are what we would refer to as
22:28
Speaker 3: exotic particles here on the Earth. They're not particles that
22:31
Speaker 3: we are familiar with in terms of the kind of
22:35
Speaker 3: material that make up our own bodies, you know, just
22:38
Speaker 3: atoms and protons and neutrons, electrons. They can be more
22:41
Speaker 3: exotic things than that, different types of both bosons and fermions.
22:47
Speaker 3: And again, without going into the depths of particle physics,
22:51
Speaker 3: just say these are these are non garden variety forms
22:57
Speaker 3: of matter, and if they're out there in large numbers,
23:01
Speaker 3: they could be making up the components of what we
23:04
Speaker 3: have referred to over the last couple of decades as
23:06
Speaker 3: this weird stuff called dark matter. Why is it dark
23:08
Speaker 3: because we can't see it and it doesn't really interact
23:11
Speaker 3: with light, yet it seems to be there and affecting
23:14
Speaker 3: the gravity of everything around. Well. There's been a several
23:18
Speaker 3: published research articles, but a new one that just came
23:21
Speaker 3: out in what's called the Monthly Notices of the Royal
23:24
Speaker 3: Astronomical Society. It's from a group of astrophysicists in Argentina,
23:30
Speaker 3: from the Institute of Astrophysics in Argentina and Laplata, Argentina,
23:34
Speaker 3: and they've come out with a new idea to say,
23:36
Speaker 3: what if instead of a black hole, what if you
23:39
Speaker 3: had a giant assembly of nothing but dark matter in
23:45
Speaker 3: the center of the Milky Way, And could that actually
23:49
Speaker 3: produce all of the things that we can measure that
23:53
Speaker 3: we've long associated with Sagittarius A being a supermassive black hole,
23:59
Speaker 3: like you have the velocities of stars around it. Could
24:03
Speaker 3: you have the magnetic field that's responsible for generating the
24:06
Speaker 3: radio waves, could you have all of these components? And
24:09
Speaker 3: the latest study has come out and suggested that many
24:13
Speaker 3: of the kinds of things that we have measured here
24:17
Speaker 3: on Earth and we have associated with properties of a
24:19
Speaker 3: super massive black hole can in fact be created by
24:23
Speaker 3: large collections of non normal or fermionic dark matter. All right, so,
24:31
Speaker 3: Valentina Crespy, one of the researchers from the Institute for
24:35
Speaker 3: Astrophysics in Laplata in Argentina, said this, according to Universe
24:40
Speaker 3: today dot com. Quote, surrounding Sagittarius A, a star cluster
24:45
Speaker 3: of young and massive stars, coexist with a population of
24:49
Speaker 3: dust and shrouded objects whose astrometric data can be used
24:53
Speaker 3: to scrutinize the nature of Sagittarius A. An alternative to
24:58
Speaker 3: the black hole scenario has been recently proposed in terms
25:03
Speaker 3: of a super massive compact object composed of self gravitating
25:09
Speaker 3: fermionic dark matter unquote. And again without going into the
25:16
Speaker 3: depths of all of the things that they're measuring, they
25:19
Speaker 3: have associated many of the measurements that we make here
25:22
Speaker 3: on Earth that we have assumed we're coming from a
25:25
Speaker 3: super massive black hole with this giant, self gravitating fermionic
25:30
Speaker 3: dark matter lump. So if that can continue to be
25:36
Speaker 3: validated with new series of observations, this would be one
25:40
Speaker 3: of those moments where maybe we need to rewrite the
25:44
Speaker 3: textbooks about how galaxies form, what's at the center of
25:48
Speaker 3: those galaxies, and what produces the initial gravity that caused
25:52
Speaker 3: galaxies to aggregate in the first place. And this is
25:56
Speaker 3: just why I'm not saying any of this is true.
25:58
Speaker 3: I'm just saying a reasonable hypothesis with some kind of
26:04
Speaker 3: some kind of reinterpretation of observations we've already made, is
26:08
Speaker 3: being put forth. And when that happens, that's when science
26:12
Speaker 3: really needs to take a close look at what they've
26:14
Speaker 3: assumed to be true and go out and do measurements
26:17
Speaker 3: to find out if it's indeed true, because it has
26:20
Speaker 3: a challenger in terms of the theoretical idea. Really fun
26:24
Speaker 3: stuff and exactly the way science works.
26:27
Speaker 1: More made of stars.
26:28
Speaker 5: Right after this, all right, let's now transition over to
26:52
Speaker 5: what's going on at Columbus State University's co Cola Space
26:54
Speaker 5: Science Center with a another astronomy night coming up on
26:58
Speaker 5: the twenty first Saturday, And then I guess you guys
27:03
Speaker 5: have kind of a long day in store for you
27:05
Speaker 5: on March the third. Not only is that the lunar eclipse,
27:08
Speaker 5: which is not conveniently timed, can they reschedule that? It's
27:12
Speaker 5: also a day for music under the Dome. So it's
27:16
Speaker 5: a long day for you guys coming up on March third.
27:18
Speaker 3: It's gonna be a long day for some of us.
27:20
Speaker 3: And some of us might be named Sean that day,
27:23
Speaker 3: but that's okay, that's fine. I don't mind being there.
27:26
Speaker 3: So we are in the process of negotiations with two
27:31
Speaker 3: different parking garages because that's where we're going to set
27:35
Speaker 3: up for the lunar eclipse. And the reason is because
27:38
Speaker 3: that lunary eclipse is setting while it goes into eclipse.
27:41
Speaker 3: In other words, we need a high location, like the
27:44
Speaker 3: roof of a parking garage, so we can look down
27:47
Speaker 3: low as the sun sets, hopefully not behind trees, which
27:50
Speaker 3: is why we're going to be on top of the
27:51
Speaker 3: parking garage so that we can see the moon. So
27:54
Speaker 3: by the time we do this podcast next, I will
27:56
Speaker 3: have that venue to announce everybody. But we will be
27:59
Speaker 3: doing on March third an observation of the lunar eclips
28:05
Speaker 3: and we will be on one parking garage or another
28:08
Speaker 3: companion who gives us permission, and we'll make that announcement
28:12
Speaker 3: by next week. So you know, if you're in the
28:15
Speaker 3: Greater Columbus area and you want to get up and
28:16
Speaker 3: see the lunary eclipse, we will be somewhere where you
28:19
Speaker 3: can join us, and we will tell you next time
28:21
Speaker 3: here on the podcast. In the meantime, as Wes said,
28:23
Speaker 3: there is an Astronomy Night on February twenty first, and
28:26
Speaker 3: there are astronomy nights coming up all throughout the spring.
28:29
Speaker 3: If you want to know that schedule, get online go
28:32
Speaker 3: to www dot CCSSC dot org. Charlie Charlie SamSam Charlie
28:38
Speaker 3: dot Org's the website for the Space Science Center and
28:41
Speaker 3: you can find out about the astronomy nights, the music
28:44
Speaker 3: under the Dome schedule, including March the third, and also
28:48
Speaker 3: our Georgia Stem Day which is happening on March fourteenth.
28:52
Speaker 3: We just posted up details for that event. That's a
28:56
Speaker 3: great event. If you know any middle or high school
28:58
Speaker 3: students who might be considering pursuing a degree in science, engineering,
29:03
Speaker 3: or technology, come check out all the vendors who will
29:06
Speaker 3: be here that day. Their vendors not trying to sell
29:08
Speaker 3: you something. They're actually vendors who are manufacturers, trying to
29:11
Speaker 3: give you information about how to pursue degrees in science
29:15
Speaker 3: and technology to work in the great paying fields that
29:18
Speaker 3: those degrees represent. So once again, check out the website
