Doors I prefer to think of it Dear John and Hank.

It's a podcast where two brothers answer your questions, give you a advice and bring you all the weeks news from both Mars and AFC Wimbledon. John. Well, what was my joke? I had it before.

I'll tell you a little bit of behind the scenes for you all. When Hank does the intro to the podcast, about 60% of the time, I can actually hear the moment when he realizes he has not prepared a dad joke. I'd like to tell you what the moment is. The moment is he says hello and welcome to Dear Hank and John, a podcast where we review different, nope that's my podcast, a podcast where we answer questions for my do-be-see-bice and bring you all the weeks news from both Mars and AFC Wimbledon.

It is in the moment before the end, every week with Mars and the moment where he's like, oh, right, a dad joke. It's like a quarter of the time. Anyway, John, why does the toilet paper roll downhill? Why?

It always rolls downhill because it just wants to get to the bottom. Really glad you prepared that one in advance. I want to simplify. I feel like I've been trying too hard.

I wanted to be more dad jokey. I know what you mean. I agree that some of the setups lately have been convoluted. I think that was an example of not trying quite hard enough.

I think there's a middle somewhere where there's a joke to the joke. Do you want an alt? I have an alt this week. See, I'm definitely prepared.

What I want is for you to take that alt and have it ready next week until we do the intro to the podcast. It's like 25% of the time that I forget. Over-estimated. Well, I work very hard.

I appreciate it. I know that it is not easy to find these dad jokes on the internet. To the extent that the internet is a useful tool and a productive tool for humans, it is mostly a way of having GPS and a repository of dad jokes. Those are the two primary productive functions of the internet.

Whoa. You all right there? My computer's made a loud noise. I don't like that noise.

That's the noise that means you have a meeting in one hour. So let's get going. John, you want to answer some questions from our listeners. I have some questions from our listeners.

Beginning with this one from Samantha who writes, you're John, I think I'm currently reading the New York Times bestseller, The Anthropocene Reviewed by critically acclaimed author John Green. Thank you, Samantha. It's a great first sentence to a question. I'm on the chapter about Sunsets.

And the question I have is if you wanted to continuously see the sunset, how fast would you have to travel? Sunsets and salamanders, Samantha. It depends on where you are. That's true.

Because if you're at the equator, I believe it's about a thousand miles an hour. But correct me if I'm wrong, here, Hank, if you're at the North Pole and it's the right time of year, it's zero miles per hour. Yeah, you just stand there. Because basically what you're talking about here is you want to be moving as fast as the Earth is going.

So you're like counteracting the spin of the Earth by walking a thousand miles an hour in the opposite direction. But the Earth spends at different speeds at different places because the Earth has different circumstances at different places. So if you imagine the widest part of the circumference of the Earth is the equator. And then it's thinner as it goes to the top until functionally, mathematically, the Earth has zero circumference at the very tip.

So if you're just standing there, you are just sort of spinning in place. Right. Matt, that's, I mean, that's Earth math. But if you're at the North Pole, you couldn't continuously see the sunset, right?

Because at some point, like the seasons will change and it'll start, it'll be the part of the year where it's going all the time. So if you want to continuously see the sunset, I think your best bet is to go a thousand miles an hour at the equator for the rest of your life. Right. And then by continuously, you mean until you die, I assume Samantha, there's not like a, if you wanted to see the sunset for like six hours, that would be a whole lot easier.

Yeah. But I love the idea of becoming a billionaire, you know, like working really hard to become a billionaire. And then instead of having your crazy billionaire project that doesn't help anybody, but you be the ones that have been picked so far, you because you're a crazy billionaire project that doesn't benefit anyone except for you, the project of spending the rest of your life continually, sweet watching a sunset. So there are all these refueling planes that have to like dock with your planes.

You're on this constant thousand mile an hour travel around the equator. They've got to like, you know, like cancel all the flights that are going to like come through yours because you're going Mach 1.4 or whatever, like you're in a hurry to keep to keep this sunset going. Yeah. And that's just that's how Samantha lives out the last 40 years of her life.

I was trying to figure out if there's like a space station place where you could do this, but there's not really a sunset if you're not on Earth. No. And in fact, your plane, I think would have to be fairly low to sort of get the full sunset effect. Yeah, you're right.

You would lose the vibe if you got, if you got too high up. There is an orbital sunrise, which is actually what I wrote the last episode of the Anthropocene Reviewed about if you want to listen to that episode of the podcast. An orbital sunrise happens every 90 minutes on the International Space Station. So every time the space station orbits Earth, the sun rises or, you know, they experience the sun is rising from behind Earth's crust, which is exceptionally beautiful.

And the first artwork ever made in space was made by the cosmonaut Alexi Leonov. And it was a drawing of that experience of seeing an orbital sunrise. But I don't think it's, it doesn't look anything like an Earth sunset. Yes, different, because you don't get the clouds.

That's the best part. I mean, it's the atmosphere that makes a sunset. And that makes so much else. All of that.

Yeah, all the man, that little thing, this thing with the vapor makes everything possible. Speaking of which, John, I want to ask you a question about mosquitoes. Good. I hate them.

It's from Jen. It's from Jen and Maddox who asked, Dear Hank and John, we just got out of a car full of mosquitoes. Well, that sounds bad. Yeah, I don't like it.

I wasn't too surprised when they were flying around and attacking us while we were parked. But when we got into the highway and we were going like 70 miles an hour, they're still just casually flying around the car. What's going on? Those mosquitoes find 70 miles an hour blood meals on wheels, Jen and Maddox.

I'm a little perplexed by what Jen thought. Jen and Maddox thought was going to happen. Like where the mosquitoes just going to get pushed back against the back wall. The car forces were going to be so high that they were just going to be like thrown into the drunk.

Yeah. Well, so like, I've been trying to figure out how to explain how to like communicate effectively what's actually happening here, which is that like, and I haven't run up against a great way yet. So John, imagine it this way. What if instead of being full of air, you imagine the car as being full of jello and your car starts going and the jello does like maybe push back a little bit into the back of the car, but it's jello.

So mostly it just pushes forward and then like, you know, it was maybe a little bit harder to get your car going because it was full of this massive delicious strawberry delight. But you're like, you're traveling 70 miles an hour and the jello, the back wall of your car, has pushed the jello forward along with the car. That's what happened except the jello isn't jello, it's air. Yeah, which is why if you'd rolled down the windows, the mosquitoes would have had a very different experience at 70 miles an hour, because yeah, it would have been it would have been a turbulent situation for them.

Yeah, because you would have at that point had them interacting with air that on some level is going 70 miles an hour now because of the way that like cars work now, you don't necessarily feel all of that inside the cabin. But like, yeah, when the what you need is to roll down the windshield and the back windshield. Yes. And then you will not have any mosquitoes in your car.

That's how you solve the problem. You roll down the windshield and the back windshield. Yeah, you will not have any mosquitoes. You will have some mosquitoes in your teeth.

Yeah, but not in the car. Yeah, yeah, you basically need to be traveling in a dune buggy. This is your first error is to attempt to de-skeitify your car instead of just selling the car covered in mosquitoes, because it's over. Yeah, that car and buying a dune buggy, which is the best way to get around town and electric dune buggy.

Everybody says that's the future. That's 70 miles an hour. It's very safe. And since we're answering a lot of questions about physics, which is certainly my area of expertise, just ask my high school physics teacher.

I want to ask this question from Elliot who writes, and I do not know the answer to this question, Elliot's. Spoiler alert, Elliot writes, Dear John and Hank, I'm five. Well, first off, Elliot, very impressive. Just that.

Rarely do we get emails from five year olds that contain anything but gibberish. I am five and I have a question. Yeah. Why does the solar system spin from Elliot?

Great sign off, Elliot. I love it. I've almost underrated sign off from. Yeah, no, see that much.

It had a moment. Yeah. It's like, I just wanted you to know because emails generally start out like two, so and so from Elliot. Yeah.

It's in there already. Heck, why does the solar system spin? Yes. Well, you said you had an idea.

Why don't you give me yours? Okay, Elliot, here's my guess. Gravity. Oh, I mean, yeah, I did it.

It's gravity. It's essentially that's there's two components. Oh, dang it. Gravity is one of them is the other one.

Like, isn't there a large black hole at the center of the Milky Way galaxy that the whole Milky Way is kind of rotating around. Yeah. And we're kind of rotating around it because it's a big gravitational center. And but why are we spinning, Elliot?

Why are we? Why are we rotating? Well, what what would happen if we weren't? We would get sucked into that black hole.

Yes. So what has happened to everything that's not spinning? It already got sucked into that black hole. There it is.

Okay, Elliot, so we're spinning because we haven't yet been sucked into a gigantic black hole. Not yet, not at all. We won't. It won't happen.

We are spinning. God. It's great news for Elliot and for me. So like, so there is back to the solar system.

And now, like, the sun would be the black hole in our solar system. And if you were thinking of the galaxy, then you've got that sort of center of mass, the center of mass. So the sun is there. But it's not there as like a thing for us to spin around.

We all as a solar system, we have a collect like every thing in the solar system has a shared center of mass and that center of mass is inside of the sun. And wiggles around a little bit as the planets go by, but mostly it's the exact center of the sun, like over over a, you know, a significantly long period of you average it out. It's the center of the sun. So yeah, we were explaining this to a five year old, you don't have to get distracted by like whether or not it's like six inches to the left of the exact center of the sun.

I did. We're all spinning around the very center of the sun. Yeah. And the sun is spinning around the very center of the sun.

But there were things in the solar system that were had a direction. So they had momentum in a direction. And those things, they did knock into each other and that would change their their momentum. But but a lot of that stuff just kept on going in that direction, but is is sort of being drawn constantly toward the sun, but is also headed in a direction.

So there is other action that is going and other action that is being pulled. And when those things cancel out into a nice circle, then you have or lips, then you have something orbiting something else. That's how basically we are constantly falling into the sun, but we're going so fast that we miss it. Okay, I feel like we had Elliot and then we lost him.

And when I say we had Elliot, I mean, we had me. Okay, John, I'll explain it like you and Elliot are both five. Okay, it's spinning because it's always been spinning. So there's nothing there to slow us down in space.

And so we keep on spinning because we were spinning when it started out and we're still spinning even today. Unfortunately, Elliot, we weren't spinning when it started out. We were, but no, not at the very beginning. We this planet was not orbiting a sun and that sun was not part of the galaxy for quite a while, actually.

Yeah. And since the beginning of the solar system, it's just been a long time just any stuff. For a long time, we have been spinning around a center of gravity, which is near the center of the sun. And for a long time, the galaxy has been spinning around a center of the galaxy, which is near the center of the galaxy.

Well, it is the center of the galaxy. It's near the center of a supermassive black hole. It is near the center of a super massive black hole. We did it sort of.

Elliot, please let us know how we did from Hank, and we did great. We did much better with a Jell-O in the car. That felt like it made sense. Yeah.

Can we answer a question that's not about science, please? Yes. This one's from Rosa who asked, Dear Anken John, should Hagrid's three-headed dog Fluffy have had three names since he had three heads? Is it a he?

I thought Fluffy was a she for some reason. Is he three dogs or one dog? I only have one head and that one's name is Rosa. Rosa, congratulations on in the vast geography of all of human imagination, finding the one hill that I am ready to die on.

Oh, wow. All right. I'm excited about this because I don't have very strong opinions. Well, I guess I do.

I'm not. I'm thinking about it, but you go first. Three heads, three minds, three dogs. Fluffy is not a dog.

Fluffy is one third of the three dogs that were protecting the philosopher's stone. So Hagrid only had one pet and the other two dogs was not his pet. No, I'm saying that Hagrid and I don't mean to disparage him, but Hagrid failed to acknowledge the fundamental reality that he had three pet dogs that shared one set of legs. Yeah.

And also shared one name or was there just one of the dogs named Fluffy? No, you got to have you got to have three names if you have three. Oh, I agree with you. But in this like mess up that Hagrid did, did he name one of the dogs Fluffy or did he wrongly imagine his pet he wrongly understood what was happening.

I agree with you. John, what are the other dogs names? I think Buffy and Ruffy. Buffy and Ruffy in neither of them are named Manhole really?

Stop. Stop trying to make pets named Manhole happen. It's not good. It's not good.

It's not as good as you think it is. It's not great. What about Fluffy and Fluffy and Fluffy? I like Ruffy.

I've always liked Ruffy as a dog name because they do make kind of they ruff a little bit. Ruff, ruff, ruff, ruff. That's one of the noises. Yeah.

You know, my all time favorite dog name is Willie, his name and my dog because as the veterinarian said to me once, you call him Willie because he's Willie, Willie cute. Oh my God. And I was like, that is, that's a great name. But I'm also very fond of extremely dignified dog names.

You know, like if you name your dog after like a Roman emperor. Yeah. I could see that. The thing about Fluffy is not only was Fluffy three dogs.

Fluffy was not fluffy. Fluffy was a short haired shiny short haired dog. At least in the movie. Not fluffy at all.

Very weird, Haggard. Yeah, for sure. But to me, like that's a little pedantic. Whereas true.

If you do it has three minds, it is three creatures. Like what makes us us is a mind. And what makes a dog a dog is its mind. I'm thinking of Fluffy pancake and scooter.

Why didn't you mention why didn't you say pancake before? Pancake is a phenomenally good dog name. What about pancake waffle and fluffy? If you like that so much.

No, I don't want to go too heavy on breakfast. And if we do go heavy on breakfast, I'd want to go a little more obscure like French toast or or like omelette. Omelette is not bad. But you always want to be a little more specific.

You know, I'm a geeze. Right. Or I was thinking a little more like vegetarian, like a like rampant spinach omelette. And fluffy and it's called ramping pancake and rampant spinach omelette.

Now I want this dog to have more heads. I don't know if heads. I mean, I don't actually know how three had a dog's work, but I feel like you're right. I don't want to I don't want to read too much into this, Hank.

But I think I think what makes a person a person is their mind and not the four legs. And so fluffy has to be three dogs. I'll be his three dogs. I'm there with you, John.

Do you have another question for me? Yes. This was from Jesse here at your head. You're John and Hank at the start of COVID one thing became clear to me, which is that I don't have any idea how soap works.

I blindly trust it. And I'm a bit of a neat freak. But what the heck is soap? Hands sanitizer alcohol.

That makes a little bit of sense to me, but I'm still not even sure what that is. Don't burst my sanitized bubble, but does soap work? Not Jesse. Yeah.

Soap super works. Soap is so good. Soap is way better than hand sanitizer even. It's great.

It's incredible. What? What a discovery. I mean, yeah.

Well, and it's been around for a long time, but more than like the discovery of its own power. It's amazing how you can have a technology and not realize how powerful it is for a long, long time. Yeah. Yeah.

Like we knew that soap made things better, but we didn't necessarily have the best understanding of why. But now that we've got a pretty good idea of it, it's incredible. So good. It's so good.

Yeah. And so soap is the basic idea is that there are two, there are things that are soluble in water and there are things that aren't and soap is very good and water is good at dissolving away the things that are soluble in water. But soap is good at helping water does all the way the things that are not soluble in water. And it also like makes water like wetter like it like water.

You have noticed this about water like you pour it into a cup and then like it's that bubble on top. Water is really good at sticking to itself. And so that can actually make it because it's so busy sticking to itself. It can be worse at sticking to other things.

So soap actually gets in between the water molecules a little bit and it says stop sticking to yourself so much. Let's stick to other stuff and then and that makes it much like water is much more effective at washing things away. You will notice especially if you have something that's not water soluble on your hands like butter or peanut butter like greasy greasy stuff that just water will not do it. But the moment you put some soap on your hands, it's like, oh, there it went away.

But that is also true of lots of little things that are kind of hydrophobic or just or just water soluble and like water gets better at being wet when it has a bunch of soap in it. And that in turn allows the water to wash away dirt and viruses and bacteria and other stuff that you don't want on your hands or other parts of your body or sharpie, which if you've written Sharpie all over your face, yeah, it speaks to how effective soap is that it is able to help water remove Sharpie because it is not easy to remove Sharpie without soap. I can tell you. It's amazing.

Like after project for awesome, I will go it'd be like it's like three in the morning. I go inside and I just like soap the Sharpie off my face so that my wife doesn't have to wake up till I can't cover Sharpie. Yeah, that is scary. That would be a frightening thing to wake up to.

So in summary, soap is an extremely effective technology. It is actually better at cleaning our hands and our bodies than even hand sanitizer is. It's amazing. I am very thankful for it.

And we're not and we're not just saying that because our mom owns a goat soap making company. She doesn't anymore actually. She's she got out of the goat soap making business. So now we are truly disinterested observers who are no longer being funded by big soap, which might be done.

This podcast isn't brought to you by big soap. It's brought to you by little soap. Little soap. It's like big soap but like way more chill.

And they're really in favor of people doing it. However, they want to do the soap thing. Little soap. That's the that's the future.

Today's podcast also brought to you by Nissan Central full of Jello and Nissan Central full of Jello, mostly a thought experiment. I hope so. This podcast is also brought to you by Samantha Sunset chasing Spaceplane. The sunset never goes down when you are Samantha the billionaire in the space plane.

God, when you're a billionaire, ask yourself this question. Yes. Does this disproportionately benefit me and people like me? Or does it disproportionately benefit the people who are not like me?

And then use that answer to guide your choices. I just I know that I know that very few of the people listening to our podcast are billionaires. I understand that we have never done well with a billionaire demographic. But I just ask yourself that question.

Just just ask yourself that question. Today's podcast is I'm sorry. I didn't mean to go on a rant. Today's podcast also brought to you by naming your pets manhole.

It's a terrible idea. Don't do it. I should say I feel like we should say that that's a reference to an old podcast episode. So people don't very don't think that like you just invented the idea of naming your pet manhole.

They all know about manhole. John, nobody we have no new listeners. We do. We don't we do we do.

First off, we do. Secondly, we have new listeners all the time. I'm constantly shocked by the number of new listeners we have. I thank you new listeners for listening.

I appreciate you Hank. Doesn't even acknowledge your existence. Sorry. John, what were we doing?

Oh, this is a project for awesome messages from Caleb. It's from Caleb fory to Sam and Regina Rodriguez. Thank you for accepting me when I came out to you. It means a lot to me to know that the people who have been my side for so long and that I have always been happy to be there for are still going to stay by me as I begin my newest journey as I transition.

You were the best found family a trans girl could ask for my eternal love to you. Oh, it's lovely. That's very sweet. Caitla, thanks for donating to the project for awesome.

Yeah, thanks for being awesome. This episode of your Hank and John is brought to you by Shopify. There are a lot of things that stand between I have an idea and this is an idea that actually exists in the world and people are buying things from me. And that is what Shopify makes easier.

When you start with Shopify, the tools to design and launch and take payments, they're all there from day one. You don't have to build a whole machine before you can start building the business. And this is important because you also have to look good and with Shopify's templates, you could get a site set up really quick that looks credible and professional without needing to code or duct tape a bunch of different tools together. And when things look real, that works on my brain to be like, I'm doing a real thing.

It also works on other people's brains to be like, this is legitimate. Shopify also has one of the best checkout systems on the internet. It's built to help customers finish the purchase effectively and efficiently without a bunch of roadblocks. Returning customers can check out with a single click.

That means less friction and fewer abandoned carts and a smoother experience for everybody. That stuff gives you confidence early on and it gives other people confidence in what you're doing. You're not wondering whether the payment system is going to work. You're not wondering whether customers can get through the process.

Shopify handles that foundation so you can focus on the thing that you're actually trying to do. It's really kind of amazing to me that Shopify is a tool that works from the first day your store launches when you're just starting to get customers all the way up to being the size of good.store or dftba.com or being the size of like Mattel and Gymshark. When you build a Shopify, you're building with tools that already work at every scale. All you need is the idea Shopify handles the rest.

Hank, let's answer a couple more questions before we get to the all important news from Mars and AFC Wimbledon. Beginning with this question from Martha who writes, deerhank, why do speedometers on most cars go so far past, even like the Texas speed limits? What are the chances that I'll be in a situation where I will have to drive 180 miles per hour? Not an old lady, Martha.

I associate the name Martha with old ladies, I have to say. I know a lot of young Martha's. I know some young Martha's too. I feel like Martha, maybe it's making a comeback.

So here's the thing I didn't know that I found out while researching this question. A lot of car manufacturers use the same speedometer, no matter what car it gets put into. So they have these like fancier, faster luxury cars that are like, part of the whole thing is, you're not gonna drive it 180 miles an hour, but you could. They will put that in there, just in case, I guess, you're going down a hill and you really don't care about your own life or the rules that you could do that.

And then they put that also in the other cars that are cheaper and definitely not capable of going over 110. But do they do it so that you feel like your car is powerful and capable of great things, even though you would never call upon it? Like it must be some kind of psychological trick, right? I, yeah, I don't know.

Like I feel like with a fancier car, you'd like wanna feel like it. And also there's sort of, like I feel like if I was driving at like 80 miles an hour and my speedometer was almost near the end of where it could go, like that might stress me out a little bit. Like I kind of want it to be up near the top when I'm going at max speed, rather than all the way down to the bottom. I'm talking about the radial speedometers now, a lot of people, and I have a car like this that just has like the number on the dashboard.

Mr. Fancy Pants over here with his numbers on the dashboard. I, it was a Honda Civic, thank you very much. I have only driven one car that I think could reasonably go 180 miles an hour and it was really driving the pace car for the Indianapolis Grand Prix.

Okay. I was really confused about where that was going. And I mean, even driving in a straight line on a race car track where people regularly drive 240 miles an hour, I was not able like an empty, totally chill, utterly perfect condition situation. I could not bring my body, the car was willing, the car was able, but I could not bring myself to go more than 100 miles an hour.

Like it was terrifying to be going that fast. I, I, it was so scary. I was going that fast on like this long straightaway and then right behind me, Simon Pajano, it's just, it was tailgating me within inches, within inches of me. And I was like, we are going way too fast.

You do not have a two second following distance Simon Pajano, like this is much, much too close. This is, so I understand letting people throw out the first pitch at a baseball game, but having watched people throw out first pitches at a baseball game, I would give them a car. I know, why would you let them drive a pace car? And then I, I was like, I was telling myself before this all started, I was like, okay, well look, they obviously it's not a big deal because they're letting me do it.

So, and dummy can do this. And I'm gonna be just fine. And then I read that once a pace car driver at the AD&AP was 500, like ran into a photographer's stand and like seriously harmed a lot of people. And then I was like, oh no, oh God, I could mess this up.

And the consequences could be extreme. Fast forward one week. And that's part of the reason I didn't go very fast, much to the annoyance of Simon Pajano, who apparently was like on the radio being like, what's wrong with this pace car driver? And the answer is that I'm a cautious driver.

I'm a defensive driver. I believe in a two second following distance. Okay, like I'm not, there's a reason that I didn't choose race car driver as my career. And flash forward to the next week, there's a race in Detroit and they have another like, you know, 17th tier celebrity pace car driver.

And he freaking crashes. Ah, he freaking spins the car and crashes into the barriers. And then it's on like the sports center, not top 10. Yeah, everybody's talking about it.

Oh my God. I'm not worth it. I dodged a bullet. Not worth it, man.

So do a number of things that I am surprised by. Like for example, that time that you were in a, like an automotive race with Maggie Steve Otter. Oh, that was just a weird phase of my life, man. It was very strange.

I was so confused. I know I did dirt track racing with her. Although to be fair, I wouldn't call it racing. I would call it losing.

I was not in anywhere near the same capacity that the brilliant novelist and semi professional race car driver Maggie Steve Otter was bringing to that event. Like she brought talent and skill and plug and a good car. And I brought nothing. You brought the guy said, when if you get in the crash, just stay in the car.

And then you got in the crash and everybody was like, why are you staying in the car? And you're like, that's what they told me to do. And they're like, not if the car is on fire. Oh God, I don't, I really don't like reliving that memory.

I did get a trophy out of it though. There's a lot that I'll do for a trophy in this world. I don't know about you Hank, but I love a trophy. All right, John, do you want to go behind the scenes about what it's like to be a YouTuber with this question from Evan?

Great. Dear Hank and John, Evan asks, on a recent Vlog with his video, how we fix the climate, the thumbnail changed like five times. First it was a screen grab of Hank, then it was a little graphic that sort of looked like Earth. And then there was another that I can't remember.

And now it's a picture of the globe. And it says there is good news. Why did it change so much? Who changes it?

Why do people change their thumbnails? Do they get more attention and clicks that way? Not a YouTuber, Evan. Yeah, that was me.

That was me. I worked really hard on that video and I wanted a lot of people to watch it. So I was trying to find a thumbnail that more people would click on. And I was trying to find a video that was really important on YouTube.

And the way that Hank and I choose almost all of our thumbnails is ever since 2007, back when we started on YouTube in 2007, the thumbnail was the center frame of the video, the exact middle frame. And so you could thumbnail cheat. Like some people would put up something salacious or really visually interesting on that middle frame so as to like try to get more clicks. But most of the time, Hank and I, it would just be whatever image of us happened to be the middle image as we were talking in the video.

A lot of people would custom thumbnails. Even though we know that if we did, it would increase views because you can increase views and decrease the quality of the experience for the community and that's something that we don't want to do. Because a lot of times, if it's people or casual viewers or people who maybe come from other corners of YouTube, they may not come in with the best intentions and it can just be kind of a bummer. So we generally just still use whatever thumbnail is algorithmically generated and don't come up with custom thumbnails.

But on videos that we want people to view that we do want the public to look at like Hank's video about climate change and, you know, what actionable things need to actually happen in order for the situation to get better. Hank was trying to find a good thumbnail so that people would watch the video. And by the way, it totally worked. Half a million people have watched the video.

Yeah, yeah, and also it's 60 minutes long, which helps because YouTube really likes it when, videos are longer, so we have our spending more time on the website. But yeah, there is, I think, I mean, I know, very potassium put a great video on why this happens. And, you know, we don't do it a lot on Vlogbrothers, but we do it on SciShow. And- Oh yeah, crash course.

We do it to an extent sometimes. And like lots of YouTube, and it's not great. Like it's not a great user experience because it's like, did I see that video already? I feel like I did, but it doesn't look the same.

So you, and some people think that people are trying to trick people and to click on it twice. So like watching the second time, that is not what's happening. In fact, when that happens, it's actually bad for the video because it means that you click on the video and then don't watch it, which YouTube kind of marks as a negative, obviously. And yeah, but it is because the click-through rate of a thumbnail matters a great deal.

So the number of people who are exposed to it and then go on to click on it is sort of the thing that videos live and die by on the platform. I will confess that it is such a big deal that sometimes when a creator, who I really like, has uploaded a video that I don't particularly want to see, I will nonetheless click on it. And I will watch the seven minute video only to tell the algorithm, even though I didn't want to see this one, I do actually want to see the next one. Yeah, and other people also should see this.

Maybe not me, but other people. Right. Yeah, it is, especially now, you know, a huge percentage. Like Hank and I are outliers on YouTube in a lot of ways.

And we're especially outliers in like the number of our views or the percentage of our views that come from subscriptions and subscribers. But these days on the platform, like subscribers matter so much less and the, you know, how many people the video is exposed to matters so much more, that the click-through rate essentially decides the fate of the video. It does, absolutely. It's the click-through rate.

And how long people watch? That's basically all it is. Yeah. And so we have a very high click-through rate with our people.

And in extreme, click-through rate with people who are casual YouTube viewers. And I think that's OK most of the time. Yeah, absolutely. And that's why, like, honestly, it works better for us to just have it be our faces.

So people are like, oh, there's the new Vlogbrothers video. And if we do a thumbnail that doesn't have our face and people are like, I don't know what that's like, John, or if that's something just weird. Yeah, they'd have to like notice that it's a Vlogbrothers video. So the main takeaway there is we are so grateful to have an audience that's stuck with us.

So we, yeah, and also we want to continue to try and make that worthwhile for both sides of the equation. So we do try to make good videos. Yeah, I mean, we are so, so fortunate to still be able to do this after 15 years. And that Nerdfighteria continues to be such a productive, interesting, cool community.

It is the great luck of our lives. And I honestly don't think it has that much to do with us. So we're really fortunate. Agreed.

John, do you have some news from AFC Wimbledon? I do. I do. AFC Wimbledon lost a football game.

It's not my favorite. I have to say, I'm so deeply in love with this team that when we lose a football game, I'm mostly just confused. How can this have happened to us, the greatest football club in the world? But more than losing a football game, the biggest surprise was that we didn't score any goals.

We went down one no, and I was like, well, that's good, because that's how what's, how we always go. That's how we win. First we start losing, and then we come back to win. But it was a game against Plymouth Argyle, the same team that we played in the playoffs final at Wembley.

We became a third tier English soccer team. And that was very exciting. And honestly, if we lose to Plymouth Argyle, every time we played them for the rest of all time, I don't care because we won the time that mattered the most. So it was a little bit of a disappointment.

I mean, honestly, it was a really poorly refereeed game. Rosie Ana was there. And it was just a weird game. We looked pretty good, but we just never were able to put it together in the final third or get really good shooting opportunities.

Iubasal had one one-on-one opportunity with the goalkeeper and just couldn't quite get around him. And so, yeah, we lost a football game, but I will say this, after eight games, we're in seventh place, which is pretty good. Yeah. Yeah, it's weird that the franchise currently applying its trade in Milton Keynes.

Yeah, you did. It's in third. I know. It is weird.

It is weird. It's uncomfortable. I would like to see them closer to 20 second or 23rd. But the season is long.

We played them in October. Let's see how things go. OK, what's the news for Mars? In Mars news, John, I've got some new information about collapsing ancient super volcanoes.

So there are these craters on Mars. That for a long time, we thought were just impact sites, but there's been debate about whether they are impactors or whether they are volcanic calderas. So like the collapsed area that falls down after a bunch of stuff explodes out of a volcano. I think American geologists were studying the craters in Arabia, Terra, which is the region.

And they wanted to figure this out. So they created a mathematical model of the pattern of volcanic ash that you would expect to be dispersed as those volcanoes erupted. And then they studied images of the surface of Mars to see if they could see ash in the places that the model predicted they would be. And indeed, they found ash there.

So they were able to determine that these craters are indeed old volcanoes. So about 500 million to 4 billion year old volcanoes. And they probably released a bunch of water vapor and carbon dioxide and sulfur dioxide when they erupted. And they would have had a really big impact on the climate, possibly making the atmosphere thicker or blocking up the sun during this sort of like tunnel-chuous early history of Mars when it was a probably wetter, warmer place than it is now.

And it would have had a thicker atmosphere as a result of those volcanic eruptions the same way that our atmosphere has gotten thicker during periods of intense volcanic activity. Yeah. Yeah. And there's sort of like a double effect.

One, right upon the eruption, usually there's a period of like much less like colder period where the sun can't reach the surface. Yeah, it sounds like it through. And then afterward, you have all this water vapor and carbon dioxide and the atmosphere that's going to trap the heat and so it gets warmer. Mm.

Yeah. That's pretty cool. Mars, just finding out more things about our good old planet friend. It's a good planet.

I mean, it's my second favorite one. John, how fast did the cars go? In the Indy 500, they go up to 240 miles an hour. That's too fast.

I agree. And there are also a lot of times three to six inches away from each other. It's not just how fast they're going. It's also how close they are.

Man, that's intense. That makes me uncomfortable. Well, I drove in the two-seater while I didn't drive. I rode in the two-seater, which is like an Indy car that has been refashioned to have a back seat.

And the Indy car driver, Sarah Fisher, drove me around the track at 180 miles an hour, which is significantly slower. And I was in the back there. Thankfully, she couldn't hear me because the car was traveling 180 miles an hour. I was behind her.

So my sound waves were getting flowed backwards pretty quickly. But I mean, pretty much for the first turn, I was like, stop the car. Stop the stuff. Stop the vehicle.

And then my husband, Chris, did it too. And he got out and he was like, the whole time. I just couldn't stop thinking, I'm such a big person. They don't know how big I am.

I'm going to be the reason that the car wiggles out in the back end and then just slams into the wall. And I was thinking that too. I was like, there is no way a car going this fast can stay on the track. And that was 60 miles an hour slower than they usually go.

And they're not riding in the back screaming, stop the car. They're driving it. They're making choices. Oh, God, well.

That's a special talent. Enjoy your hobby. I will enjoy mine. Yeah.

And that goes for everybody. Enjoy your hobbies. We're not here to yelk on your yelms. We're here to celebrate yelms, whether they be Martian or Wimbledonian.

That's right. I'm just much more comfortable podcasting rather than speed driving. Yeah, me too. That's what the call it.

I think that is. Yeah. That's what do you do for a living? I'm a speed driver.

It's what his Hamilton says. Whenever he's interviewed, Max Verstopen is always like, I'm a speed driver. Did you say his name is Max Verstopen? If his name is Verstopen, he should stop.

Oh, you're not. He should be slow. Oh, God, man. What does his name?

What did you say? Max Verstopen. OK, it's Max Verstopen. All I hear is Max Verstopen.

But I guess that's what you say. That's pretty close to his name. Yeah. John, thank you for making a podcast with me.
