Speaker 1 (00:03):
Welcome to Stuff to Blow your Mind from how Stuff
Works dot com. Hey, welcome to Stuff to Blow your Mind.
My name is Robert Lamb and I'm Julie Douglas. Hey, Julie,
have you ever renovated a house? I have. I have
to tell you that wallpaper removal is the scourge of
all renovators. It's awful, that's gross. I've never had to
(00:27):
do that. I had to scrape piles off of hardwood floors,
but that's about it. I don't know. I haven't done
that actually, so I can't say if it's worse. But
I can't say that my own experience, you know, being
in a really small room, you know, filled with fumes
like fel methyl kind of stuff and trying to just
inch my inch and get you know, flowered wallpaper from
(00:50):
the nine is a horrible thing. Yellow women running around
in them and all that. Yeah, yes, because, uh, I
mean it's rough with with renovating because you often you'll
come in to a house or space that is in
some cases unlivable, and you you have to put all
this work into it just to get it up to
the standard where you can be comfortable with the fact
that you live in this space. Uh, and that's not
(01:12):
even you know, discussing the process of getting it where
you want it to eventually be exactly and if you will,
which can take forever and never happen, that's right, has
to become habitable at some point. You've got to get
the the pp shot sent out of the floor. Yes,
I sometimes there's a meth lab spas the same smell
(01:35):
catp meth lab, that's what say. But I tell you
a real fixer upper out there that that really it's
far rougher than any wallpaper issues you've had, or or
tiles on the hardwoods that I've had. And that is
the prospect of moving to the planet March. Oh yeah,
that is screaming for a redo. Yeah. That place is rough,
(01:58):
garish red color. And uh, I mean it's just you
couldn't live on March right now. That's kind of an
overstatement of the obvious. But but but you could not
live in it. You would have to ter a form it,
which is the planetary version of renovating a space. Yeah. Yeah,
And I at first I used to think about it
(02:19):
as as like a terrarium for humans, although there would
be no dome. But I like the idea of having
this gigantic terrarium on Mars filled with humans. But that's
really not what scientists are thinking. Yeah they're they're not
thinking as much as of that, but just sort of.
But but it does come down to we really wish
this place is a little more like Earth, um because
(02:40):
we want to be able to potentially live there. What
can we do to make it happen? And I go ahead, No,
I was gonna say, so, well, why why do it?
That's what I keep struggling with with this topic, like
why would you tear for Mars? Yeah, that this is
a big one because it's hard to make the argument
that we need to be on March right now unless
I mean some people, if you're Robert Superan, uh yesterday,
(03:03):
and then we should have been yesterday years ago. I Mean,
one of the big key arguments is that it has
to do with the long term survival of the human race,
that that eventually we're gonna have to become an interplanetary
uh race, We're gonna have to become an interstellar race
because we've got six billion of us right now and
we're not stopping. We're We're yeah, we're growing. There's a
(03:25):
the Earth isn't gonna last forever. And if we have
this idea that we're gonna last forever, we're gonna need
to expand out diversify our planetary portfolio. Okay, and sort
of like the lorax, We've we've done a real number
to our own environment, right, so we want to try
to maybe escape our atmosphere and go to a new
virgin atmosphere. That's all lussion. Pretty Yeah, it seems like
(03:47):
you see less of that these days, but it seems
like that was a real driving force for a while,
Like all right, well, this one's about used up. What's next.
But but at a very basic level, if we're gonna
becoming an interplanetary interstellar race, you've got to take those
baby steps. You So people talk about going to the
going to Mars, and then it expands from there. The
other side of it, and this is generally touted as
(04:08):
more of a secondary argument, is that UM, in the
same way that the Age of Discovery propelled scientific innovation,
so too would the terraforming and eventual colonization of another
world UM stir up a lot of technical innovation that
would benefit life on Earth. Yeah. Actually, I even pulled
a quote to that effect, because I thought, well, that
(04:29):
is interesting, that that's the sort of view I can
take on and say, Okay, it might be worth our
time because indirectly we would get all this technology. UM.
Dr Adrian Brown of SETI, with that Search for Extraterrestrial
Life Institute. UM, he had actually said something very similar
to that, saying that we wouldn't have invented such precise
time keeping and navigational technology if we didn't need it
(04:51):
in order to cross huge expanses of ocean to reach
frontiers in Asia, Africa, in the New World. So he's
using that same analogy for space, yeah, which I thought
was interesting. Thy, Yeah, it is. And uh. And then
there's the whole argument too that to really understand Mars,
we would need to be there now. I'm not sure
how well that holds up with our continued advances in
(05:11):
the robotic exploration techniques, but there's you definitely run across
that argument. We're saying like, if we want to we
want to get to the bottom of the possibility of
life on Mars now or life in its distant path,
and therefore understand the um evolution of life in the
cosmos better than we're going to need to be there
so well, and see I do understand the argument too,
(05:33):
but then I also kind of think, well, if you
if you have samples that are collected by robots and
sent back, you know, you have the data that you
need part of It's kind of like you have to
admit it would be just really cool to be on Mars,
and that's a reason to go. It's kind of like, um,
you know, we're as of recording this, we're planning to
go to south By Southwest to record something. It's kind
(05:55):
of like if you know, if someone were to say, look,
you really need to send us there, and we're we're
making the argument because it would also be cool, you know,
can be a little different if we just sent like
a little hologram of ourselves. Yeah. Yeah, And that was
on the table. We were saying, look, let's just been
robot explorers to south By Southwest and then we're like, no,
because we won't give the full effect and uh, you know,
and we'll also have more advanced technology for having to
(06:18):
figure out how to send ourselves to it, right, So
it's sort of a win win from Yeah, But so
I'm also wondering why Mars, Why not Venus well, Mars
is ultimately the better prospect. I mean, Venus is. I
don't want to get up on Venus. The Venus is fascinating,
but Venus is is pretty messed up. I mean it's
a hot mess. Yeah, like it's it's a hot, highly pressurized,
(06:43):
acid clouded world. And uh and and Mars it's just
a little It's like if you're looking at two houses,
Mars is the better fix it up property. I think
it's worth mentioning, like exactly what Venus is a teardown? Yeah,
Venus is more of a teardown. I guess they're our
terraforming schemes out there for Venus. But but we're gonna
focus on Mars just because it's an easier prospect to understand, um,
(07:06):
and to understand what what is what's exactly wrong with Mars? Right?
We need to I feel like we need to, we
need to look at that. So one of the big
things terrible atmosphere, just really bad. Yeah. Then, um, you know,
keep in mind that humans are involved to live in
a very small atmospheric level of our own world and
(07:27):
sort of a special sauce here that ye obviously isn't
present on Mars. Yeah, and there are layers of this
special sauce where we die. You know, if you got
to go up to the top of Everest without any
kind of transition, then you you wouldn't survive most people,
most people the serpens would do, but they're used to it. Um.
So yeah, we wouldn't get enough oxygen we die. Uh.
(07:47):
It's it's just just way too thin, it lacks efficient
air pressure and contains way too much carbon dioxide. It's
freezing to Yeah, it's also really cold. It's the to
go back to the Goldilocks idea. Venus is too hot,
Mars is too cold. Earth is just tract and if
you had just even a speck of water at the
moment that it hit the surface, it would just sizzle
and evaporate. Yes. Um. There's also an important point to
(08:11):
be made about there, the fact that there's no intact
electromagnetic field um Earth as one. It's generated by hydrodynamic
convection between the liquid outer core and the solid intercore.
And without this shielding we to be exposed to a
deadly stream of highly charged particles called the solar winds.
So uh, for reasons we don't entirely understand yet, Mars
(08:33):
lacks the protection of this electromagnetic field if they haven't,
thank you lately. Yeah, they have. Mars has like only
remnants of a magnetic field around its solar ice caps.
So that's that's it's like not having a roof on
the working roof and the mouse we'd have to figure
out how to replace the roof. Um. So yeah, it's
it's that that's pretty rough. But there's some potential in
(08:53):
Mars there. You know, there there is water on on
the on the Martian surface, there's evidence that there used
to be quite a bit right right, there's carbon and
oxygen in the form of carbon dioxide, and there's nitrogen. Um.
You know. The problem is that it's like the atmosphere
there's like ninety point three percent carbon dioxide. It's just
(09:14):
as a point as episode was it with like a
point zero one or something point on Earth? Yeah, and
then yeah, and also on Mars it's like the oxygen
there is point two percent, so really really low. So
you're gonna have to supplement with oxygen nitrogen obviously, um,
if you were to go in terraform. This in earnest
also that the rotation rate is on par with the
(09:36):
Earth's twenty four hour cycle. Yeah, and it's close enough
to the sun to experience seasons, which is always lovely
because you want seasons when you live in other worlds.
You know, you want to have your winter home on
one part in your summer home on the other, so
Richard Branson. So, so then this comes to question, what
(09:57):
would it take to fix it up, What would it
take to get that new roof on it, to bump
up the atmosphere, to scrape the horrible wallpaper off the
walls of Mars and uh and make it look pretty again. Yeah.
And there are actually some some very good ideas about this, right.
It's good in the sense that they are solutions. Yeah,
and they're based in science. Um. I think for a
(10:18):
lot of people like the idea of Like for me,
the earliest experience I have with terraforming was seeing I
think Aliens and they had the big terraforming stations and
I only had a vague idea of what it was doing.
That it was like, these giant buildings that are like
spitting out smoke are going to somehow transform this world
into a place that humans can live on. So the
(10:38):
greenhouse gas effect, Yeah, well, a lot of It breaks
down to that, like our experience and screwing up our
own world crosses over to some of the ideas for
making Mars a little more like what we want. Okay,
so we want like big coal mining factories, which you're seeing,
but basically the yeah, they're one of the ideas, the
the Aliens model, if you will, is to create these
greenhouse gas producing factories. Um you know, they would be uh,
(11:01):
the same heating effect that we have here on Earth
with greenhouse gases could be reproduced on Mars by setting
up sending up hundreds of these factories across the Martians
and releasing cfc CFCs methane, carbon dioxide, other greenhouse gases,
just pump it into the atmosphere, just basically pollution machines
on on Mars to try and it's kind of like
(11:24):
on Mars it's like the water is a little too hot,
so we'll add some some some cold water to cool
the bath down, and on Mars it is the reverse.
So that's one scheme. Another involves large orbital mirrors to
reflect the sunlight and heat the Martian surface. All right,
This would giant mirrors kind of like the ones that
(11:45):
the Soviets experimented with for the idea of of of
of giving sunlight to dark regions during the winter uh,
and these would would concentrate light onto the polar caps
and melf the ice. This would release carbon oxide believed
to be trapped inside the eyes, and the rise in
temperatures would over the years would conceivably release greenhouse gases
(12:07):
such as these CFCs and the same that you find
in your air conditioner, so like melting polar caps, and
then this would all lead to photosynthesis at some point,
right for years and years and years, and again we're
one of the things I think to think about is,
you know, you've had some people say it could take centuries,
and you have other people saying it could take thousands
and thousands of years. Yeah. One of the important things
(12:29):
that when you're talking about changing an atmosphere, you're you
get into this whole area of fluid dynamics, you get
into the into into just the chaos theory itself. Just
refreshure the idea that the chaos theory emerged from the
attempt to create more reliable computer models of weather, of
of how our atmosphere works, and the chaos theories is
(12:50):
that you can only figure it out so far and
then it just it just breaks down. So we're up
against that and trying to figure out how to tinker
with another world at fear we don't fully understand how
our own works, or we at least the thing we
understand the most about it is that it's incredibly complex.
So there are a lot of what ifs that end
up falling into it in different people's figures. Will you
(13:11):
know will say decades and another will say centuries. Well,
and then there's the whole dark matter out in space,
the fact that we don't really know what exactly it
is and how it affects planets, right so, and then
when we actually talked about this yesterday about the possibility
of smashing ammonia heavy asteroids into the planet to sort
(13:32):
of create the same greenhouse gas level effect. And this
is another one that's UH that Robert Zubrin UH is
really fond of and presented in his book A Case
from Mars. And Zubrin is a really interesting guy. I
get to interview him for a Discovery News article and
I have I don't think I've ever interviewed somebody just
so passionate about their thing, and I haven't plenty of
(13:54):
people are really passionate about their their topics and their
their their life's work. But Zubrin is in He's just
like we should be on Mars yesterday. Yeah. Yeah, I
listened to the audiophile and at the risk of um,
Robert Zubern like reaching out to me and saying, you know,
you're the devil incarnate. That dude is a fanatic. But
(14:14):
I kind of like that because you need those people,
You need that passionate level in order to be like,
we gotta do this, you know, yeah, I mean, you
got it. You need extremist or and and and and
extremely passionate people to push these ideas into the public mindset.
Otherwise there's too many people would just not listen, right
And and also you know, I know this is a
little bit of an aside. I was thinking about him,
(14:36):
and I was thinking about his role and if even
if this doesn't happen right now, I mean he he
very well maybe like the da Vinci in the sense
of his time and that you know, da Vinci had
all these drawings for flight, but obviously the technology didn't
exist until much much later. And you know, who knows
people could go down in history be like that super
and guy was righteous. He knew it I was talking
(14:57):
about and he was he was ahead of his time.
We should have in on Mars in the twentieth century.
Right that being said, let's talk about the ammonia ridden
aster which is a little bit creepy. Well, it's it's
one of the another one of these ideas. This is
very catastrophic sounding because you're talking messing with the planet's atmosphere.
It's it's very reminiscent of some of the the scenarios
(15:19):
we look at with things like nuclear winter or or
um or you know, asteroids impacting the Earth um And
this basically boils down to the belief that if you
hurled these large I see asteroids that were just full
of ammonia at marks, they would produce tons of greenhouse
gases and water. Okay, so you would need nuclear thermal
rocket engines and you'd have to somehow attach these to
(15:41):
an asteroid from the outer Solar System, and then the
rockets would move the asteroids in about four kilometers per
second for a period of about a decade before the
rockets would shut off and allow the ten billion tons
of asteroids to glide unpowered. Towards the Martian surface, and
the energy released upon impact would be about a hundred
and thirty million mega wats of power. Yeah yeah, and
(16:04):
can you imagine the dust settling from that? I mean
it would take centuries and centuries. And it's not that
you mentioned dust. That's another scheme that's out there is
to take material from a sea class asteroid or a
Martian moon and spread it over Mars polar caps. So
this would be um and another kind of drastic global
(16:24):
warming type of scheme coated with dust. The poles would
then absorb more solar radiation because remember you have you know,
you wear a dark shirt on a sunny day, you're
warmer than if you wear a white shirt. It's the
same scenario. Yeah, They absorb more sunlight, causing them to
heat up, release carbon dioxide, atmospheric atmospheric pressure increases, and
(16:45):
you'd have the greenhouse effect, and eventually we get it
up to the point where Arnold Schwartzenhager's eyeballs would explode
if he took his filmet off. That's the ultimate goal
in all things, but but also in terraform, all right,
So I mean I guess that that is the point
where then people could be supplemented with oxygen and nitrogen
to a certain degree, but not like full on like
they would need right now. Yeah, any of these schemes
(17:08):
you're looking at, it's not you wouldn't be able to
turn Mars into Idaho in a decade or center. You know,
there would be this long, slow process of where it
becomes more Idaho esque. Yeah, And I guess that that
sort of plays into the outmoded idea that this would
be a population outlet for for Earth. Right, Like, if
(17:28):
we reached billion people by the time we actually by
the time we reached twenty billion people, you'd have to
assume that we would have had some sort of solution
in place, because by the time that you can actually
have Mars habitable, it would be thousands and thousands and
thousands of years from now. Yeah, So that's one of
the arguments of like, hey, let's not try to this
shouldn't probably be our backup plan for humanity. Right. Plus,
(17:51):
I I like to or I don't like to think this,
but it seems like if the more we were we
moved towards potentially having more world peace, that's just going
to get in the way of people needing to leave here,
so we do. If we got to the point where
we have the technology to go to other worlds and
seed them with our people, you might want to make
conditions on Earth particularly hellish, and then people would have
(18:13):
a reason to flee right right right, same models the
early or just a good reason to make tons and
tons of money, which is another huge factor. Um you
get into like mining on on Mars for healing them
three and things like that, then you could conceivably see
it being a possibility. Yeah. Yeah, Halliburton's all over this. Um.
So this also kind of plays into the ethics, right,
(18:33):
there's um and there are there's actually like kind of
like a science gang war going on here, and it's
like the reds and the Greens. I'm like ketting, like
the reds are the are the folks are Like you
know what, maybe we should look at Mars and try
to keep it intact as much as possible and still
study it, but keep the integrity of it because maybe
there's something that it's ecosystem can tell us, and if
(18:55):
we were to try to tear a format, we would
sort of pollute that possibility of learning more out of it. Yeah,
it's the idea that there might be some you know,
little signs of what life may have been like on Mars,
if there was life on Mars at some point in
the past, that those those secrets are buried and those
secrets are there to be found, provided that we don't
completely contaminate the place. It seems like a controlled crime scene.
(19:18):
You don't want the bumbling local detectives to go and
local police have to come in and touch everything, because
the big city detective he needs to get in there
with all its high tech gear and figure out what's what. Right, Like,
we wouldn't want to introduce an invasive microbial species that
would just you know, lay waste to everything, because then
we'd be like, oh, we didn't learn anything really about Mars. Now,
we're just trying to fit our earthly paradigm, you know,
(19:41):
into Mars this other thing which we don't really know
about yet. So those are the reds, yes, and then
the greens, of which Zubrin is definitely a member. Um.
I mean, his whole thing is like this is actually
he put it really nicely in the interview I did
with him, um and a phrase used to this exact
example of many times. But he's like, if you were
(20:03):
to make the argument, hey, let's take um, let's take
Earth and let's turn it into a barren, lifeless world.
Let's do that. Let's let's get started this project right away,
you would say, dude, you're crazy. Don't turn don't turn
the planet, this living, lush planet into a desert. And
his thing is then the reverse is true too, that
(20:23):
the argument like, look at Marks. It's dead, it's empty,
there's nothing living there. It's a waste land. We have
a responsibility to turn it into a green world. See.
And that's the problem I have with it because it's
like absolutism, right, It's like it's dead. And I was like, well,
I don't know, because NASA actually has said, well we
you know, there are these methane plumes that keep kind
(20:43):
of unfurling in front of us, making us realize that
there's methane being released, which kind of points us in
the direction that there may be some sort of life form,
you know, at least on a microbial level, and so
we can't necessarily anounced it dead. Yeah. I guess it's
kind of like if there was like a house in
a neighborhood and it was like really crappy, and someone
(21:06):
was maybe argument, hey, we need to fix this up.
There's like there's it's doing nothing. It's just a complete ruin.
It's you know, foreclosed on. Let's let's get somebody in there,
let's get let's get this thing torn down and rebuild
or something. And then you can make the argument, well,
I fare all cats are living there those farall cats
need to live somewhere, so why not this house or
there's something making some argument that that that something natural
(21:29):
may be going on that we shouldn't stamp on just yet. Yeah,
or they might say there's a tiffany stained window in there.
You know, you can't knock that exactly. Okay, that's an
even better example. Yeah, yeah, So I don't know if
that's I think it's a very fascinating uh topic. And
I do really like the idea of technology coming out
of the maybe the thought experiment. But obviously it's something
(21:51):
that UM that we're at least in the United States,
we don't necessarily have the economic power to put a
lot of money into UM, particularly since some of these plans,
like there's a four hundred fifty billion dollar plan rolled
out in the Bush one era that was like, Hey,
we can build this orbital platform on Mars and launch
(22:12):
this and do this, and Bush was like, yeah, I
think so. And there have been subsequent plans and facts
you Ben came up with a couple of pretty good
ones that are more in like the twenty fifty billion
dollar range. Still that's yeah, that's still a lot of money.
It's I mean, it's sad to think. I mean, at
some point the past, the money made the the argument
(22:33):
that that and I forget who was saying, maybe it's
just a friend of us talking to me. They were like,
we're not gonna We're not going to see a personal
land on Mars in our lifetime. Now, whether that's true
or not remains to be seen, but just the prospects
kind of sad because you grow up watching all the
science fiction and and hearing all this science and you know,
we've been talking about landing on Mars for well over
half a century. I mean, we've been talking about it
(22:55):
longer than that, but we've had more concrete plans in
that time period, and to think it it's not going
to happen is kind of depressing because you you kind
of grow up thinking that this is where you're your
life is going to go you know, yeah, yeah, And
hence zuber In in his his impatience and saying, look,
we do have the technology, we could do it. Yeah,
(23:17):
I mean it's possible. Yeah. And of course the more
we learn, though, you know it, the more the situation
comes complicated. Because there's a two thousand ten study from
the Swedish Institute of Space Physics in the University of Leicester,
and they found that double solar radiation waves periodically strip
away thirty of the sparse Martian atmosphere, so that these
(23:37):
waves occur when one solar wave overtakes another to produce
a single like super wave. And uh, and so what
little atmosphere remains on the planet is due to comics,
comic strikes, and the occasional melting of polar ice. So
even if we so, it kind of creates this this
horrible situation. It's cut the money pit, like the more
you're going to rebuild it and then stuff is just
(23:58):
gonna bust it down. So I'm not saying we shouldn't try,
but but it it's a little disheartening to have that
added bit of information. Well, and I was thinking too
that astrobiology, which we've talked about before. Is still such
a young field in terms of the new technologies it
has at its disposal. You know what, what might it
be able to uncover in the next ten years to
(24:20):
tell us a little bit more about Mars and how
to look at that situation and look at terror forming
and new So I don't think that we have all
the data in what we're talking about. You know. Yeah,
we should definitely not shut the case, shut the lid
on the case just yet. I like to think it
will happen someday. We'll see, we'll see. Let's bring on
the mail. Yes, we do have a couple of bits
(24:43):
of mail here from some people who have some experience
with doppelgangers calling back to our Defeat Your Doppelgangers podcast. Uh,
first we're gonna hear from Matt. Matt says, Hey, guys,
love the podcast. Just listen to your show, Defeat Your Doppelgangers.
This one really hit home with me because young kid,
I always had the impression that there are were multiple
copies of myself hanging around my hometown. I never felt
(25:07):
there was any malicious intent or an evil clone. I
always knew in the back of my mind that around
any corner I might bump into a copy of myself.
I never found one, but to this day I still
have a feeling that they're out there somewhere. Also, as
a kid, I always thought that the mirror in my
bathroom or any mirror was actually a view into the
closest relative neighborhood dimension, that is to say looking that
(25:29):
is to say, a looking glass into the closest dimension
to ours. The image staring back at me was not
a reflection but the other meat from the next dimension
looking in his mirror. Uh yeah, so um, Matt, thanks
for sharing that. That's uh, that's pretty interesting. Yeah. Yeah,
my mind is a little bit low there. Um. I
also wanted to share it too. There's a comment by
(25:49):
Jane on Facebook and she was talking about our Neandertals
episode um, and she actually made a really good point
that in that episode we kept ferring to Neanderthals is
he There's like no mention of any female in Neandertals,
which of course we know that existed. Um. In fact,
that the mitochondrial DNA, and that tells us so much
(26:10):
today about what went on with Neandertals. Um, they the
possessors of it. But uh, and she also points out
that when we were talking about them making glue and
so on and so forth, we kept talking about he
knowing it. How about. You know what, that's a really
good point to make. Thank you, Jane, thank you for
keeping us sharp, because you know it's kind of hard
sometimes you fall back on that that old um he
(26:32):
pronoun is a catch all. So I just wanted to say, yes,
the menatols the ladies, they were definitely a big part
of that group. And it was interesting because a lot
of the research that I came across, at least and
especially the stuff that was produced online, shows this sort
of patriarchal paradigm of the men making the glue, and
(26:55):
like the women going through the men's hair and grooming them,
and the men barked neandertal orders out of them. So anyway, again,
thank you, Jane, and I love these comments that you
guys give us, you know, the email on Facebook, and
you guys really give us some good platforms like stuff
for our minds to chew on as well. Indeed, one
more quick Doubel ganger Eric writes, and he says, I've
(27:16):
never met anyone who could be my twin, but I
have had some problems with my name. UM my name
doppelganger is in a doppelganger that shares one's name. I
moved to Portland, Oregon, in two thousand five from the
San Francisco Bay area. When I apply for a library
card here, I was surprised to learn that there were
unpaid overdue books under my name. Turns out someone with
(27:37):
my name please don't read it on the air and
gives it gives its full name. UM is also living
in It's also living in the suburb of Portland's. The
town has a population of a little less than twenty
three people. So yeah, that happens probably more frequently we
encounter with the individuals to share our exact name, and
especially if you end up googling your own name like
(27:57):
I do, way too much. You know. It's like when
am I gonna overtake The Murder Robert Lamb? When am
I going to overtake the The he Man the animated
series animator? Yeah? Mine mine? Uh? I think kind of
like Julie Douglas has made a triathlete somewhere in Austria
or something. I can't remember having googled myself for a
long time, but I was like, go Julie Douglas. Yeah,
(28:18):
that the Julie douglas Is of the world need to
stick together and make it work right. Yeah. Yeah, just
still a little fist bump tea cans down there. Julie
Douglass is well cool. If you have any little tidbits

Welcome to Stuff to Blow your Mind from how Stuff
Works dot com. Hey, welcome to Stuff to Blow your Mind.
My name is Robert Lamb and I'm Julie Douglas. Hey, Julie,
have you ever renovated a house? I have. I have
to tell you that wallpaper removal is the scourge of
all renovators. It's awful, that's gross. I've never had to
(00:27):
do that. I had to scrape piles off of hardwood floors,
but that's about it. I don't know. I haven't done
that actually, so I can't say if it's worse. But
I can't say that my own experience, you know, being
in a really small room, you know, filled with fumes
like fel methyl kind of stuff and trying to just
inch my inch and get you know, flowered wallpaper from
(00:50):
the nine is a horrible thing. Yellow women running around
in them and all that. Yeah, yes, because, uh, I
mean it's rough with with renovating because you often you'll
come in to a house or space that is in
some cases unlivable, and you you have to put all
this work into it just to get it up to
the standard where you can be comfortable with the fact
that you live in this space. Uh, and that's not
(01:12):
even you know, discussing the process of getting it where
you want it to eventually be exactly and if you will,
which can take forever and never happen, that's right, has
to become habitable at some point. You've got to get
the the pp shot sent out of the floor. Yes,
I sometimes there's a meth lab spas the same smell
(01:35):
catp meth lab, that's what say. But I tell you
a real fixer upper out there that that really it's
far rougher than any wallpaper issues you've had, or or
tiles on the hardwoods that I've had. And that is
the prospect of moving to the planet March. Oh yeah,
that is screaming for a redo. Yeah. That place is rough,
(01:58):
garish red color. And uh, I mean it's just you
couldn't live on March right now. That's kind of an
overstatement of the obvious. But but but you could not
live in it. You would have to ter a form it,
which is the planetary version of renovating a space. Yeah. Yeah,
And I at first I used to think about it
(02:19):
as as like a terrarium for humans, although there would
be no dome. But I like the idea of having
this gigantic terrarium on Mars filled with humans. But that's
really not what scientists are thinking. Yeah they're they're not
thinking as much as of that, but just sort of.
But but it does come down to we really wish
this place is a little more like Earth, um because
(02:40):
we want to be able to potentially live there. What
can we do to make it happen? And I go ahead, No,
I was gonna say, so, well, why why do it?
That's what I keep struggling with with this topic, like
why would you tear for Mars? Yeah, that this is
a big one because it's hard to make the argument
that we need to be on March right now unless
I mean some people, if you're Robert Superan, uh yesterday,
(03:03):
and then we should have been yesterday years ago. I Mean,
one of the big key arguments is that it has
to do with the long term survival of the human race,
that that eventually we're gonna have to become an interplanetary
uh race, We're gonna have to become an interstellar race
because we've got six billion of us right now and
we're not stopping. We're We're yeah, we're growing. There's a
(03:25):
the Earth isn't gonna last forever. And if we have
this idea that we're gonna last forever, we're gonna need
to expand out diversify our planetary portfolio. Okay, and sort
of like the lorax, We've we've done a real number
to our own environment, right, so we want to try
to maybe escape our atmosphere and go to a new
virgin atmosphere. That's all lussion. Pretty Yeah, it seems like
(03:47):
you see less of that these days, but it seems
like that was a real driving force for a while,
Like all right, well, this one's about used up. What's next.
But but at a very basic level, if we're gonna
becoming an interplanetary interstellar race, you've got to take those
baby steps. You So people talk about going to the
going to Mars, and then it expands from there. The
other side of it, and this is generally touted as
(04:08):
more of a secondary argument, is that UM, in the
same way that the Age of Discovery propelled scientific innovation,
so too would the terraforming and eventual colonization of another
world UM stir up a lot of technical innovation that
would benefit life on Earth. Yeah. Actually, I even pulled
a quote to that effect, because I thought, well, that
(04:29):
is interesting, that that's the sort of view I can
take on and say, Okay, it might be worth our
time because indirectly we would get all this technology. UM.
Dr Adrian Brown of SETI, with that Search for Extraterrestrial
Life Institute. UM, he had actually said something very similar
to that, saying that we wouldn't have invented such precise
time keeping and navigational technology if we didn't need it
(04:51):
in order to cross huge expanses of ocean to reach
frontiers in Asia, Africa, in the New World. So he's
using that same analogy for space, yeah, which I thought
was interesting. Thy, Yeah, it is. And uh. And then
there's the whole argument too that to really understand Mars,
we would need to be there now. I'm not sure
how well that holds up with our continued advances in
(05:11):
the robotic exploration techniques, but there's you definitely run across
that argument. We're saying like, if we want to we
want to get to the bottom of the possibility of
life on Mars now or life in its distant path,
and therefore understand the um evolution of life in the
cosmos better than we're going to need to be there
so well, and see I do understand the argument too,
(05:33):
but then I also kind of think, well, if you
if you have samples that are collected by robots and
sent back, you know, you have the data that you
need part of It's kind of like you have to
admit it would be just really cool to be on Mars,
and that's a reason to go. It's kind of like, um,
you know, we're as of recording this, we're planning to
go to south By Southwest to record something. It's kind
(05:55):
of like if you know, if someone were to say, look,
you really need to send us there, and we're we're
making the argument because it would also be cool, you know,
can be a little different if we just sent like
a little hologram of ourselves. Yeah. Yeah, And that was
on the table. We were saying, look, let's just been
robot explorers to south By Southwest and then we're like, no,
because we won't give the full effect and uh, you know,
and we'll also have more advanced technology for having to
(06:18):
figure out how to send ourselves to it, right, So
it's sort of a win win from Yeah, But so
I'm also wondering why Mars, Why not Venus well, Mars
is ultimately the better prospect. I mean, Venus is. I
don't want to get up on Venus. The Venus is fascinating,
but Venus is is pretty messed up. I mean it's
a hot mess. Yeah, like it's it's a hot, highly pressurized,
(06:43):
acid clouded world. And uh and and Mars it's just
a little It's like if you're looking at two houses,
Mars is the better fix it up property. I think
it's worth mentioning, like exactly what Venus is a teardown? Yeah,
Venus is more of a teardown. I guess they're our
terraforming schemes out there for Venus. But but we're gonna
focus on Mars just because it's an easier prospect to understand, um,
(07:06):
and to understand what what is what's exactly wrong with Mars? Right?
We need to I feel like we need to, we
need to look at that. So one of the big
things terrible atmosphere, just really bad. Yeah. Then, um, you know,
keep in mind that humans are involved to live in
a very small atmospheric level of our own world and
(07:27):
sort of a special sauce here that ye obviously isn't
present on Mars. Yeah, and there are layers of this
special sauce where we die. You know, if you got
to go up to the top of Everest without any
kind of transition, then you you wouldn't survive most people,
most people the serpens would do, but they're used to it. Um.
So yeah, we wouldn't get enough oxygen we die. Uh.
(07:47):
It's it's just just way too thin, it lacks efficient
air pressure and contains way too much carbon dioxide. It's
freezing to Yeah, it's also really cold. It's the to
go back to the Goldilocks idea. Venus is too hot,
Mars is too cold. Earth is just tract and if
you had just even a speck of water at the
moment that it hit the surface, it would just sizzle
and evaporate. Yes. Um. There's also an important point to
(08:11):
be made about there, the fact that there's no intact
electromagnetic field um Earth as one. It's generated by hydrodynamic
convection between the liquid outer core and the solid intercore.
And without this shielding we to be exposed to a
deadly stream of highly charged particles called the solar winds.
So uh, for reasons we don't entirely understand yet, Mars
(08:33):
lacks the protection of this electromagnetic field if they haven't,
thank you lately. Yeah, they have. Mars has like only
remnants of a magnetic field around its solar ice caps.
So that's that's it's like not having a roof on
the working roof and the mouse we'd have to figure
out how to replace the roof. Um. So yeah, it's
it's that that's pretty rough. But there's some potential in
(08:53):
Mars there. You know, there there is water on on
the on the Martian surface, there's evidence that there used
to be quite a bit right right, there's carbon and
oxygen in the form of carbon dioxide, and there's nitrogen. Um.
You know. The problem is that it's like the atmosphere
there's like ninety point three percent carbon dioxide. It's just
(09:14):
as a point as episode was it with like a
point zero one or something point on Earth? Yeah, and
then yeah, and also on Mars it's like the oxygen
there is point two percent, so really really low. So
you're gonna have to supplement with oxygen nitrogen obviously, um,
if you were to go in terraform. This in earnest
also that the rotation rate is on par with the
(09:36):
Earth's twenty four hour cycle. Yeah, and it's close enough
to the sun to experience seasons, which is always lovely
because you want seasons when you live in other worlds.
You know, you want to have your winter home on
one part in your summer home on the other, so
Richard Branson. So, so then this comes to question, what
(09:57):
would it take to fix it up, What would it
take to get that new roof on it, to bump
up the atmosphere, to scrape the horrible wallpaper off the
walls of Mars and uh and make it look pretty again. Yeah.
And there are actually some some very good ideas about this, right.
It's good in the sense that they are solutions. Yeah,
and they're based in science. Um. I think for a
(10:18):
lot of people like the idea of Like for me,
the earliest experience I have with terraforming was seeing I
think Aliens and they had the big terraforming stations and
I only had a vague idea of what it was doing.
That it was like, these giant buildings that are like
spitting out smoke are going to somehow transform this world
into a place that humans can live on. So the
(10:38):
greenhouse gas effect, Yeah, well, a lot of It breaks
down to that, like our experience and screwing up our
own world crosses over to some of the ideas for
making Mars a little more like what we want. Okay,
so we want like big coal mining factories, which you're seeing,
but basically the yeah, they're one of the ideas, the
the Aliens model, if you will, is to create these
greenhouse gas producing factories. Um you know, they would be uh,
(11:01):
the same heating effect that we have here on Earth
with greenhouse gases could be reproduced on Mars by setting
up sending up hundreds of these factories across the Martians
and releasing cfc CFCs methane, carbon dioxide, other greenhouse gases,
just pump it into the atmosphere, just basically pollution machines
on on Mars to try and it's kind of like
(11:24):
on Mars it's like the water is a little too hot,
so we'll add some some some cold water to cool
the bath down, and on Mars it is the reverse.
So that's one scheme. Another involves large orbital mirrors to
reflect the sunlight and heat the Martian surface. All right,
This would giant mirrors kind of like the ones that
(11:45):
the Soviets experimented with for the idea of of of
of giving sunlight to dark regions during the winter uh,
and these would would concentrate light onto the polar caps
and melf the ice. This would release carbon oxide believed
to be trapped inside the eyes, and the rise in
temperatures would over the years would conceivably release greenhouse gases
(12:07):
such as these CFCs and the same that you find
in your air conditioner, so like melting polar caps, and
then this would all lead to photosynthesis at some point,
right for years and years and years, and again we're
one of the things I think to think about is,
you know, you've had some people say it could take centuries,
and you have other people saying it could take thousands
and thousands of years. Yeah. One of the important things
(12:29):
that when you're talking about changing an atmosphere, you're you
get into this whole area of fluid dynamics, you get
into the into into just the chaos theory itself. Just
refreshure the idea that the chaos theory emerged from the
attempt to create more reliable computer models of weather, of
of how our atmosphere works, and the chaos theories is
(12:50):
that you can only figure it out so far and
then it just it just breaks down. So we're up
against that and trying to figure out how to tinker
with another world at fear we don't fully understand how
our own works, or we at least the thing we
understand the most about it is that it's incredibly complex.
So there are a lot of what ifs that end
up falling into it in different people's figures. Will you
(13:11):
know will say decades and another will say centuries. Well,
and then there's the whole dark matter out in space,
the fact that we don't really know what exactly it
is and how it affects planets, right so, and then
when we actually talked about this yesterday about the possibility
of smashing ammonia heavy asteroids into the planet to sort
(13:32):
of create the same greenhouse gas level effect. And this
is another one that's UH that Robert Zubrin UH is
really fond of and presented in his book A Case
from Mars. And Zubrin is a really interesting guy. I
get to interview him for a Discovery News article and
I have I don't think I've ever interviewed somebody just
so passionate about their thing, and I haven't plenty of
(13:54):
people are really passionate about their their topics and their
their their life's work. But Zubrin is in He's just
like we should be on Mars yesterday. Yeah. Yeah, I
listened to the audiophile and at the risk of um,
Robert Zubern like reaching out to me and saying, you know,
you're the devil incarnate. That dude is a fanatic. But
(14:14):
I kind of like that because you need those people,
You need that passionate level in order to be like,
we gotta do this, you know, yeah, I mean, you
got it. You need extremist or and and and and
extremely passionate people to push these ideas into the public mindset.
Otherwise there's too many people would just not listen, right
And and also you know, I know this is a
little bit of an aside. I was thinking about him,
(14:36):
and I was thinking about his role and if even
if this doesn't happen right now, I mean he he
very well maybe like the da Vinci in the sense
of his time and that you know, da Vinci had
all these drawings for flight, but obviously the technology didn't
exist until much much later. And you know, who knows
people could go down in history be like that super
and guy was righteous. He knew it I was talking
(14:57):
about and he was he was ahead of his time.
We should have in on Mars in the twentieth century.
Right that being said, let's talk about the ammonia ridden
aster which is a little bit creepy. Well, it's it's
one of the another one of these ideas. This is
very catastrophic sounding because you're talking messing with the planet's atmosphere.
It's it's very reminiscent of some of the the scenarios
(15:19):
we look at with things like nuclear winter or or
um or you know, asteroids impacting the Earth um And
this basically boils down to the belief that if you
hurled these large I see asteroids that were just full
of ammonia at marks, they would produce tons of greenhouse
gases and water. Okay, so you would need nuclear thermal
rocket engines and you'd have to somehow attach these to
(15:41):
an asteroid from the outer Solar System, and then the
rockets would move the asteroids in about four kilometers per
second for a period of about a decade before the
rockets would shut off and allow the ten billion tons
of asteroids to glide unpowered. Towards the Martian surface, and
the energy released upon impact would be about a hundred
and thirty million mega wats of power. Yeah yeah, and
(16:04):
can you imagine the dust settling from that? I mean
it would take centuries and centuries. And it's not that
you mentioned dust. That's another scheme that's out there is
to take material from a sea class asteroid or a
Martian moon and spread it over Mars polar caps. So
this would be um and another kind of drastic global
(16:24):
warming type of scheme coated with dust. The poles would
then absorb more solar radiation because remember you have you know,
you wear a dark shirt on a sunny day, you're
warmer than if you wear a white shirt. It's the
same scenario. Yeah, They absorb more sunlight, causing them to
heat up, release carbon dioxide, atmospheric atmospheric pressure increases, and
(16:45):
you'd have the greenhouse effect, and eventually we get it
up to the point where Arnold Schwartzenhager's eyeballs would explode
if he took his filmet off. That's the ultimate goal
in all things, but but also in terraform, all right,
So I mean I guess that that is the point
where then people could be supplemented with oxygen and nitrogen
to a certain degree, but not like full on like
they would need right now. Yeah, any of these schemes
(17:08):
you're looking at, it's not you wouldn't be able to
turn Mars into Idaho in a decade or center. You know,
there would be this long, slow process of where it
becomes more Idaho esque. Yeah, And I guess that that
sort of plays into the outmoded idea that this would
be a population outlet for for Earth. Right, Like, if
(17:28):
we reached billion people by the time we actually by
the time we reached twenty billion people, you'd have to
assume that we would have had some sort of solution
in place, because by the time that you can actually
have Mars habitable, it would be thousands and thousands and
thousands of years from now. Yeah, So that's one of
the arguments of like, hey, let's not try to this
shouldn't probably be our backup plan for humanity. Right. Plus,
(17:51):
I I like to or I don't like to think this,
but it seems like if the more we were we
moved towards potentially having more world peace, that's just going
to get in the way of people needing to leave here,
so we do. If we got to the point where
we have the technology to go to other worlds and
seed them with our people, you might want to make
conditions on Earth particularly hellish, and then people would have
(18:13):
a reason to flee right right right, same models the
early or just a good reason to make tons and
tons of money, which is another huge factor. Um you
get into like mining on on Mars for healing them
three and things like that, then you could conceivably see
it being a possibility. Yeah. Yeah, Halliburton's all over this. Um.
So this also kind of plays into the ethics, right,
(18:33):
there's um and there are there's actually like kind of
like a science gang war going on here, and it's
like the reds and the Greens. I'm like ketting, like
the reds are the are the folks are Like you
know what, maybe we should look at Mars and try
to keep it intact as much as possible and still
study it, but keep the integrity of it because maybe
there's something that it's ecosystem can tell us, and if
(18:55):
we were to try to tear a format, we would
sort of pollute that possibility of learning more out of it. Yeah,
it's the idea that there might be some you know,
little signs of what life may have been like on Mars,
if there was life on Mars at some point in
the past, that those those secrets are buried and those
secrets are there to be found, provided that we don't
completely contaminate the place. It seems like a controlled crime scene.
(19:18):
You don't want the bumbling local detectives to go and
local police have to come in and touch everything, because
the big city detective he needs to get in there
with all its high tech gear and figure out what's what. Right, Like,
we wouldn't want to introduce an invasive microbial species that
would just you know, lay waste to everything, because then
we'd be like, oh, we didn't learn anything really about Mars. Now,
we're just trying to fit our earthly paradigm, you know,
(19:41):
into Mars this other thing which we don't really know
about yet. So those are the reds, yes, and then
the greens, of which Zubrin is definitely a member. Um.
I mean, his whole thing is like this is actually
he put it really nicely in the interview I did
with him, um and a phrase used to this exact
example of many times. But he's like, if you were
(20:03):
to make the argument, hey, let's take um, let's take
Earth and let's turn it into a barren, lifeless world.
Let's do that. Let's let's get started this project right away,
you would say, dude, you're crazy. Don't turn don't turn
the planet, this living, lush planet into a desert. And
his thing is then the reverse is true too, that
(20:23):
the argument like, look at Marks. It's dead, it's empty,
there's nothing living there. It's a waste land. We have
a responsibility to turn it into a green world. See.
And that's the problem I have with it because it's
like absolutism, right, It's like it's dead. And I was like, well,
I don't know, because NASA actually has said, well we
you know, there are these methane plumes that keep kind
(20:43):
of unfurling in front of us, making us realize that
there's methane being released, which kind of points us in
the direction that there may be some sort of life form,
you know, at least on a microbial level, and so
we can't necessarily anounced it dead. Yeah. I guess it's
kind of like if there was like a house in
a neighborhood and it was like really crappy, and someone
(21:06):
was maybe argument, hey, we need to fix this up.
There's like there's it's doing nothing. It's just a complete ruin.
It's you know, foreclosed on. Let's let's get somebody in there,
let's get let's get this thing torn down and rebuild
or something. And then you can make the argument, well,
I fare all cats are living there those farall cats
need to live somewhere, so why not this house or
there's something making some argument that that that something natural
(21:29):
may be going on that we shouldn't stamp on just yet. Yeah,
or they might say there's a tiffany stained window in there.
You know, you can't knock that exactly. Okay, that's an
even better example. Yeah, yeah, So I don't know if
that's I think it's a very fascinating uh topic. And
I do really like the idea of technology coming out
of the maybe the thought experiment. But obviously it's something
(21:51):
that UM that we're at least in the United States,
we don't necessarily have the economic power to put a
lot of money into UM, particularly since some of these plans,
like there's a four hundred fifty billion dollar plan rolled
out in the Bush one era that was like, Hey,
we can build this orbital platform on Mars and launch
(22:12):
this and do this, and Bush was like, yeah, I
think so. And there have been subsequent plans and facts
you Ben came up with a couple of pretty good
ones that are more in like the twenty fifty billion
dollar range. Still that's yeah, that's still a lot of money.
It's I mean, it's sad to think. I mean, at
some point the past, the money made the the argument
(22:33):
that that and I forget who was saying, maybe it's
just a friend of us talking to me. They were like,
we're not gonna We're not going to see a personal
land on Mars in our lifetime. Now, whether that's true
or not remains to be seen, but just the prospects
kind of sad because you grow up watching all the
science fiction and and hearing all this science and you know,
we've been talking about landing on Mars for well over
half a century. I mean, we've been talking about it
(22:55):
longer than that, but we've had more concrete plans in
that time period, and to think it it's not going
to happen is kind of depressing because you you kind
of grow up thinking that this is where you're your
life is going to go you know, yeah, yeah, And
hence zuber In in his his impatience and saying, look,
we do have the technology, we could do it. Yeah,
(23:17):
I mean it's possible. Yeah. And of course the more
we learn, though, you know it, the more the situation
comes complicated. Because there's a two thousand ten study from
the Swedish Institute of Space Physics in the University of Leicester,
and they found that double solar radiation waves periodically strip
away thirty of the sparse Martian atmosphere, so that these
(23:37):
waves occur when one solar wave overtakes another to produce
a single like super wave. And uh, and so what
little atmosphere remains on the planet is due to comics,
comic strikes, and the occasional melting of polar ice. So
even if we so, it kind of creates this this
horrible situation. It's cut the money pit, like the more
you're going to rebuild it and then stuff is just
(23:58):
gonna bust it down. So I'm not saying we shouldn't try,
but but it it's a little disheartening to have that
added bit of information. Well, and I was thinking too
that astrobiology, which we've talked about before. Is still such
a young field in terms of the new technologies it
has at its disposal. You know what, what might it
be able to uncover in the next ten years to
(24:20):
tell us a little bit more about Mars and how
to look at that situation and look at terror forming
and new So I don't think that we have all
the data in what we're talking about. You know. Yeah,
we should definitely not shut the case, shut the lid
on the case just yet. I like to think it
will happen someday. We'll see, we'll see. Let's bring on
the mail. Yes, we do have a couple of bits
(24:43):
of mail here from some people who have some experience
with doppelgangers calling back to our Defeat Your Doppelgangers podcast. Uh,
first we're gonna hear from Matt. Matt says, Hey, guys,
love the podcast. Just listen to your show, Defeat Your Doppelgangers.
This one really hit home with me because young kid,
I always had the impression that there are were multiple
copies of myself hanging around my hometown. I never felt
(25:07):
there was any malicious intent or an evil clone. I
always knew in the back of my mind that around
any corner I might bump into a copy of myself.
I never found one, but to this day I still
have a feeling that they're out there somewhere. Also, as
a kid, I always thought that the mirror in my
bathroom or any mirror was actually a view into the
closest relative neighborhood dimension, that is to say looking that
(25:29):
is to say, a looking glass into the closest dimension
to ours. The image staring back at me was not
a reflection but the other meat from the next dimension
looking in his mirror. Uh yeah, so um, Matt, thanks
for sharing that. That's uh, that's pretty interesting. Yeah. Yeah,
my mind is a little bit low there. Um. I
also wanted to share it too. There's a comment by
(25:49):
Jane on Facebook and she was talking about our Neandertals
episode um, and she actually made a really good point
that in that episode we kept ferring to Neanderthals is
he There's like no mention of any female in Neandertals,
which of course we know that existed. Um. In fact,
that the mitochondrial DNA, and that tells us so much
(26:10):
today about what went on with Neandertals. Um, they the
possessors of it. But uh, and she also points out
that when we were talking about them making glue and
so on and so forth, we kept talking about he
knowing it. How about. You know what, that's a really
good point to make. Thank you, Jane, thank you for
keeping us sharp, because you know it's kind of hard
sometimes you fall back on that that old um he
(26:32):
pronoun is a catch all. So I just wanted to say, yes,
the menatols the ladies, they were definitely a big part
of that group. And it was interesting because a lot
of the research that I came across, at least and
especially the stuff that was produced online, shows this sort
of patriarchal paradigm of the men making the glue, and
(26:55):
like the women going through the men's hair and grooming them,
and the men barked neandertal orders out of them. So anyway, again,
thank you, Jane, and I love these comments that you
guys give us, you know, the email on Facebook, and
you guys really give us some good platforms like stuff
for our minds to chew on as well. Indeed, one
more quick Doubel ganger Eric writes, and he says, I've
(27:16):
never met anyone who could be my twin, but I
have had some problems with my name. UM my name
doppelganger is in a doppelganger that shares one's name. I
moved to Portland, Oregon, in two thousand five from the
San Francisco Bay area. When I apply for a library
card here, I was surprised to learn that there were
unpaid overdue books under my name. Turns out someone with
(27:37):
my name please don't read it on the air and
gives it gives its full name. UM is also living
in It's also living in the suburb of Portland's. The
town has a population of a little less than twenty
three people. So yeah, that happens probably more frequently we
encounter with the individuals to share our exact name, and
especially if you end up googling your own name like
(27:57):
I do, way too much. You know. It's like when
am I gonna overtake The Murder Robert Lamb? When am
I going to overtake the The he Man the animated
series animator? Yeah? Mine mine? Uh? I think kind of
like Julie Douglas has made a triathlete somewhere in Austria
or something. I can't remember having googled myself for a
long time, but I was like, go Julie Douglas. Yeah,
(28:18):
that the Julie douglas Is of the world need to
stick together and make it work right. Yeah. Yeah, just
still a little fist bump tea cans down there. Julie
Douglass is well cool. If you have any little tidbits
to add, or just want to interact with us, then
