Hey. Earth. The moon. The sun. Who rotates around who? Huh? Hey? That's a head scratcher, isn't it?

Something to think about. And I don't know about that. With me. That one seems familiar. Wait, it's something to think about on the podcast? It's just something to think about, isn't it? You don't have to think long about it. You probably know the answer.

Do you know the answer? But then you'll have some nut jobs that will fucking say different. That's true. Yeah. Well, there's no moon. And the earth is flat. And we spin. Yeah, yeah.

And the sun's just a really bright lamp from Home Depot. It's like a 200 watt or something. And no shade. No lamp, no shade. Those planets with multiple moons, they must be fun places, right? Yeah. You get to look up and be like,

oh, they're... You get to visit them all. You get to look up and go, there's two. I guess it would wear off eventually. What a planet. What a planet. We may have no trees and there's maybe a desolate place with no oxygen, but check out our moons.

We've got 30 moons. In my planet, we only have one moon. What a planet. Welcome, Satya. I got gigs coming up. Will this be before Hawaii? It is, yeah. All right, come and. Welcome, Sacha. I got gigs coming up. Will this be before Hawaii? It is, yeah. All right, come and see me, Maui.

August 5th. August 5th, August 6th in Honolulu. And then I'll be in Las Vegas at the wonderful Mirage Casino, 12th and the 13th. Come out and see me then. They're always fun shows. I'm going to, you know, I'm going to be. Then you're going to be at Tucson, August 26th.

I'm match fit. I just came off a big tour. And then Tucson, yeah, I'll do that one. Tucson, I need to advertise that one. You're going to do that one too? August 27th, Agua Caliente Resort Casino and Spa. Yeah, come out to the casino and spa. Rancho Mirage, if you can find it.

I'm going to a lot of Mirages. Everything's Mirage. Yeah. All right. Whenever you see a Mirage, it's never got a hotel on it, though. It's always just, oh, there's water over there. I've never seen a Mirage, have you? Oh, yeah, many times.

You haven't? It's just the heat line. Yeah. Many, many times. I've seen the heat. That's not a Mirage. Yeah, when you're driving out to Vegas, you'll see Mirages all the time. Yeah, when you go, oh, that looks like a body of water over there. It's just the heat wave. I feel like any time you're at an amusement park on out to Vegas You'll see mirages All the time Yeah when you go Oh that looks like

A body of water over there It's just the heat waves I feel like anytime You're at an amusement park On a hot day There's mirages All over the parking lot I don't see any hot girl

Next to a pond No no no That's the Bugs Bunny fucked it For everyone Oh okay He was always like Crawling through the desert

There'd always be like A hot thing And you know A palm tree And shit There's no palm trees No No

It's just water It just looks like water Yeah okay And then follow us On Instagram I think Forrest Really didn't know palm tree and shit. There's no palm trees. No. It's just water. It just looks like water. Yeah, okay. And then follow us on Instagram. I think Forrest really didn't know there wasn't any palm trees. I thought there was a hot girl. I thought it was like a delusional thing.

Yeah, but even if that's like now that I'm married, you know one of the great freedoms of being married is you can be as hot as you want. I don't give a fuck. Get out of the way. But hold on a second. I don't give hot people special preference anymore. My whole life I've given hot people like, hey, can I pick that up for you?

Oh, I'll get that door for you. And they go through life like that. Open your own damn door. You don't want to be a hot chick around me. I'm fucking meaner. I'm just like this. Fuck off. Get out of the way.

You're bloody taking up space with your stupid bag. If they're hot, they always have a big bag they always have one they've always got dumb bags that's $20,000 they haven't paid for the dumb bags they've been given that they show off with their dumb bags fuck you and your dumb bags fuck hot chicks am i right yeah hashtag fuck hot chicks hot chicks not like in a good way, not like fuck hot chicks, like fuck them. Like screw them. Oh wait what's the word? Yeah, yeah, Jack be careful you're about to become an incel

Hot chicks be damned Hot chicks be damned Hashtag hot chicks be damned. How about damn y'all to hell hot chicks. No, I don't want them dead or anything, they still do a service, I like them in porn and stuff like they're still good to have around selling products. But I don't want them dead or anything. They still do a service. I like them in porn and stuff. They're still good to have around. Selling products.

But I don't engage with hot people anymore. I used to engage with hot people all the time. Now I don't give them any special preference. What about ugly people? In fact, I tip the ugly more. The uglier you are, the bigger the tip. Because you're like, things have been hard for you. Yeah, I am.

I'm like, yeah, that person needs to be. It's good that you finally came around and saw the light there. Yeah, I used to like, I used to be like getting bottle service from a hot girl and be like, oh, make sure I give a good tip. Thank you, sir. Thank you so much. And now I'm like, you get no tip.

You've had the best life ever. So what's the scale from hot to ugly tip percentage? Oh, obviously hot zero. No, but you've seen me. Sometimes I'll slip. Look, I've done thousand dollar tips in front of you, right? Well, my favorite one was at the Waffle House.

Yeah, but she was the hottest girl at the Waffle House. But she was still working at the Waffle House. I respected her hotness versus her job. And I thought, that's pretty cool. A hot chick working at the Waffle House. She's humble enough to work at the Waffle House. She deserves some money. Did we tell this? No, I don't think we did. You had chick working at the Waffle House. She's humble enough to work at the Waffle House. She deserves some money. You had never been to a Waffle House.

Did we tell this? No, I don't think we did. You had never been to a Waffle House. Lisa Curry was on the road. Neither of you have been to a Waffle House. You got to go to a Waffle House. They actually cook the food fresh. Where was this?

It was in between. Kansas. Was it? Yeah. Between Kansas and wherever else we were driving. Might have been Des Moines. Kansas and Des Moines, actually. Oh, yeah.

We're in the middle of nowhere. The food's good. They cook it open air. You can see it it's fresh but they're all built the exact same if you've been to walf house ever there's a counter on the very end where you can look straight down the whole everything's sticky yeah you can go straight down the kitchen look and so lisa got up to go to the bathroom we're done with them we gotta go to the bathroom and then jim gets them gets the the bill pays it and i didn't know this but you had tipped her like 200 bucks maybe no six hundred dollars six okay yeah it was a lot of money on a probably a thirty dollar bill i might have been four it was it was a lot of money there's a lot of money and she comes back and she goes are you did you make a mistake or

is this and then you said no no that's great she starts crying and then she walks down and then other waitresses get around her kind of like comforting her. And they're like, some of them are crying and they're like, thank you. But then it got to the point where Lisa's still in the bathroom and me and you are just sitting there.

It's uncomfortable. Yeah, you want to do the mic drop and like, no problem. And then they're like, who is that mystery man? And why was he in a Waffle House he must be a billionaire they probably pulled tips so I made them cry they might do that but then they're

like oh and then Jim just goes we gotta leave now yeah yeah I agree so we leave and I think Lisa just it was like near the beginning when she started touring with you and she got in the car and she was like did I do something wrong because you guys are in the car already we're like we gotta go let's get in the with you and she got in the car and she was like, did I do something wrong? Because you guys are in the car already. We're like, we got to go.

Let's get in the car. You're fine. Get in the car. We got to go. We did a good deed. We got to leave now. The shittier the restaurant, the nicer the service,

the uglier the person, the bigger the tip. I have a Zen diagram. So an ugly person in a really shitty restaurant is going to make... Who is trying hard or someone...

Okay, so this one... We'll have to draw it out. That girl was not ugly, by the way. She was very attractive. She wasn't ugly. Who is trying hard or someone here. Okay, so this one. We'll have to draw it out. That girl was not ugly, by the way. She was very attractive. She wasn't ugly. So her tip could have been bigger. Oh, yeah.

If she was ugly, she would be owning a house by now. Would have been $200. Yeah, her good looks cost her. Can't have it all, lady. That'd be a lesson to you. Yeah, the less teeth the better I'll get that

I tipped a girl a thousand bucks in a in a Denny's and I've been to Denny's about twice in my life it was a Denny's in Vegas and she just had a good attitude I'm like there's so many restaurants in Vegas where you know you probably get really good tips and this girl's working in fucking Den's, man.

And so I gave her a big tip. And same thing. Every time I've done this, someone's chased me out of the store to tell me I've made a mistake. They've gone, you've made a mistake. And I go, probably. Probably shouldn't have. I've met many, which one are you referring to?

They just ride with it. You know what I mean? But I did it because I saw there was this family and they just left fucking food on the floor and this girl was just under there and she just cleaned it up with a dustpan and she was like working at Denny's. And I went, no, she needs a break.

Yeah. No, it's nice. Every now and again, if someone needs a break. I never tip big. I'll tip the 20% in like a Michelin star restaurant or something like that. I tip properly every day. Yeah, that's still a ton of money.

Yeah, it's still a ton of money, but i don't do a stupid like hey guy who looked like his life is together you good-looking model because we're getting a restaurant with a 500 dollar bill nine times out of ten you'll get like someone cries but i stupidly once in the soho house tip like 200 on a drink or something because someone was giving good service and the and the girl was like thanks for that and i was I was like, oh, no, I need tea. I'm generous, but I need a little bit of waving your face. It's a solo answer. No, they're not.

Yeah, what am I doing that? So, yeah, the shitty, if you're working in a Norm's, right, and I walk in, just treat me nice because i'm in a norms and that's my that's my wheelhouse every diner is going to be fighting over you as as soon as you walk in yeah but they're not see that that's jim jeffrey he's at my table i had a blow i was i was in the car the other day i was being picked up from the airport and the guy in the car he's like he's like uh do i know you from somewhere he's doing that in the revision mirror i said ah i he's like, do I know you from somewhere? He's doing that in the revision mirror. I said, ah,

I don't know you, so I doubt you know me. It would be rare that we didn't know each other. And he goes, and he goes, I've got it. He goes, you're that famous soccer player. He goes, I've got it, I've got it, I've got it. And I went,

yep, Manchester United. I just fucking got it and I went yep Manchester United I just fucking I didn't tell him at the end or nothing that's such a compliment he thinks I'm like Ryan Giggs or something and so I was like

yeah Manchester United ah yeah been out of the league for a while and he goes it looks like you keep yourself in good shape yeah I try to

take me take me to the check But I did say, what's your name? Jim Jeffries. Jim Jeffries, Manchester United. Right, right. Oh, my God. Yeah, yeah, yeah. Because of the accent, he just meant soccer player, right?

So he would have told people, I had Jim Jeffries from Manchester United. But I didn't just play at Manchester United. I followed the whole career of David Beckham. I played for a small time with Real Madrid and then I played a small time with the LA Galaxy before I retired. Isn't there a Jim Jefferies coach or something? He coaches, yeah. I met him once, yeah.

He used to coach Hearts in Edinburgh, which is like an Edinburgh team. And then they were like, I was doing the Edinburgh Festival and they said, okay, bring out on the pitch Jim Jefferies. And they were like I was doing the Edinburgh Festival and they said okay bring out on the pitch Jim Jefferies and they were like what? You're not Jim Jefferies ah what?

and then he came out and we were like what? we have the same name and then they gave me a jersey with a two and he had the one and he had the two

and we both had Jefferies on it so I've still got that it's all the same or did it go? you had the E too well besides Jim's shows you can see those

at jimje Jeffries.com. And then our podcast, follow that at ID cap podcast on Instagram. Patreon.com slash my wife's account, Victoria Beckham and her new fashion. I have a new podcast too, with Dave Williamson, the merman podcast.

I don't know that. Listen to that. And anything else? And all merches up at idontknowaboutthat.com all right time to welcome our guest calvin phillips g'day calvin now it's time to play yes no yes no yes Judging the book by its cover. You sang it, huh? You sang it today.

In tune, man. Oh, wow. Good job. Okay. Calvin's got magnifying glasses behind him. Does your specialty of specials, does it involve magnification? No. You've got a lot of books that are stripy for no apparent reason. I think that's the reflection of the blinds.

All your books look like you've wrapped them for Christmas. I think that's the shadows coming in the way. Yeah, but I'm saying what I can see. You've got a globe of the earth back there, but it isn't really round. So are you not a flat earther, but are you an oval earther? Like the oval is, the earth is kind of oval it's kind of it's not it's a sphere is it okay someone seems a bit picky about this

i'm on a trail i'm on a trail is it about the earth uh loosely loosely it's not is it about that one's trying to throw you off i mean i mean it could loosely be that, but no, it's not. Is it based in reality? Yeah. Because you could be talking about science fiction or something like that or a movie. Well, it is based in reality, but it also is in science fiction a lot. Yeah, there are a lot of movies.

It's based in reality, but this topic also is included in a lot of science fiction. Is it gravity? That's a pretty good one. But gravity has something to do with it, too. Gravity works against this. Oh, is it about my testicles? That's how you know Calvin. He's an expert.

That's why he's got that magnifying glass. Do you want me to give you a hint? I've already got it. Give me a hint. Okay. Five, four. It's about NASA. Yeah, it's a close theory.

About rockets. Rockets. There you go. So you're a rocket man? Yeah. All right. Oh, yeah, you're covering up rocket radio. Calvin Phillips is a rocket propulsion engineer at Firefly Aerospace.

He has previously worked at NASA, the Aerospace Corporation, and the John Hopkins Applied Physics Laboratory. He graduated with a master's in aeronautical and astronautical engineering from Purdue University and a bachelor's in aerospace engineering from Georgia Tech. Space is space is his passion. Two episodes back. How do you ever make fun of Jim for real?

And has always dreamt of building vehicles to get us there. You can find him on Twitter at Cal D Phillips Jr. So it's C-A-L-D-P-H-I-L-L-I-P-S-J-R. I get all the hard stuff right, and I get the wrong stuff. Anyways, Calvin, thanks for being here. So, Calvin, do you use the joke all the time that it is rocket science? Like when people say, oh, it's not rocket science, you go,

it's not like this is rocket science. Oh, wait a minute, it is. Do you do that? I would do that all day. I don't personally use that joke, but people always make that joke referring to me all the time. Yeah, he's a rocket scientist. Yeah, that would be good.

Is it as difficult as brain surgery? No, it's harder. Is it? Is rocket science harder than brain surgery? How do you know? How many brains have you done surgery on? I've done rocket surgery. Yeah, but like a brain with a scalpel and all that stuff.

I don't know. What do I have? Are you so smart that I'd have you as my phone-a-friend on Who Wants to Be a Millionaire? No, I'm pretty bad at trivia. Oh, well, there you go. Only about rockets. Only if the question was about rockets.

Very specific. You'd be like, I have my phone-a-friend as Calvin. This is about geography. No phone be like, I have my phone in front of Calvin. This is about geography. No phone in front. Okay, so we're going to ask Jim some questions about rockets. And at the end of those questions, you're going to grade all of his answers on the

accuracy. Zero through ten, ten's the best. Kelly's going to grade him on confidence. I'm going to grade him on et cetera. We're going to add those all together. Zero through ten, rocket mortgage. You know what that... I don't think it's a good mortgage to add those all together. Zero through 10, rocket mortgage. You know what that is? I don't think it's a good mortgage. I don't know. 11 through 20, pocket rocket.

21 through 30, Elton John. Yeah, he's a rocket man. Yeah. You wouldn't have put him in the space, though. I don't reckon he would have lived. He's still alive. Yeah, no, but I don't think he would have been a person you could have put in space.

I think right now, at his age, you could test him. He's got a pacemaker. That's the thing, though. Can people with pacemakers make it to space? First question. I love when they do those tests. What are we sitting John Glenn up again for? See what it's like for old people? It's like it's a publicity stunt. No, we're doing tests on old people.

Alright, here we go. Check his vitals. What is the definition of a rocket? That's an interesting question. It is. what is the definition of a rocket that's a interesting question it is like like what is the definition of a rocket i'd go it's a rocket like thing um a rocket needs to have a propulsion on it that shoots it upwards into the air um it would a rocket involves um gasoline and fuel and all that type of stuff and needs to be filled you can't just go like like you know you get nerf rockets where you just a bit of air and

the thing shoots out i think that a proper rocket needs a jet propulsion uh type of engine on it. Okay. What are rockets used for? Well, for fun, if you like talking like fireworks and stuff like that, just for a bit of fun. Otherwise, to bomb other countries or to get up missiles and rockets. Now, that's going to be a big debate if they're the same thing. I believe a missile is a rocket. Rockets will take you up into space and they'll shoot you up into the sky. And the rocket propulsion isn't the actual spacecraft. It's the thing that gets you up into the atmosphere.

Okay. What is rocket science's proper name? Rocket science, probably the name would be aeronautical in a space propulsion. Okay. Where and when did rockets originate? The first ever rocket would have been the Russians would have done something and they would have taped the chimp to the side of it with fucking gaffer tape just to see how it went or something like that.

I would have said the Russians invented rockets. Where do they get the chimps in Russia, huh? Well, okay, where do rockets really come from? What's ancient aliens, man? He fucking knows. The aliens came down. We stole their technology. The Nazis tried to improve it, blah, blah, blah, blah, blah.

Here we are, rockets. But without aliens, we wouldn't have rockets. Why are fireworks relevant when discussing rockets? Because they're little tiny rockets. Okay. And so you start off with that. That would be your first, like, that's like when you experiment on a mouse to see if that medicine will work on humans.

You start off with a firecracker and you work your way up. Okay. Isaac Newton came up with three laws that govern our world. These laws are the laws of what? You know this. The laws of not

the theory of relativity, the laws of relativity. Relativity you're going to go with? Yeah. But it's the fucking What goes up must go down Uh-huh Always be nice to people

Uh-huh And Don't eat meat on Fridays Okay I think you got it What's the difference between velocity and acceleration? Acceleration Is how Is how Is how fast and how much you're ramping up.

Velocity is the G-forces coming back onto you. Okay. How fast do rockets go? We'll break it down. First stage and a second stage. How fast do you think they go? First stage. 700 miles an hour.

You can do kilometers per mile an hour. 700 miles an hour. 700 miles per hour. Second stage. 1,000 miles an hour. Okay. do kilometers per mile an hour? 700 miles an hour. 700 miles per hour, second stage. 1,000 miles an hour. Okay. What is propulsion? Propulsion?

Fucking hell, I'm going to sound dumb on this one. Julia, do you know? You said it a billion times already. You kept saying propulsion. I know, but I don't know how to explain these things. My friend Julia's here. She didn't know about the topic either. What's propulsion?

I would think it would be something where there's like a chemical reaction or something that has to happen. You're worse than me. I did go to Arizona State. Oh, okay. Oh, I thought you were going. I did go to aeronautical school. Aeronautical inner space.

I did go to PHDM. Inner space propulsion. No, propulsion. Propulsion. Propulsion. What do you do when your shoulders hurt? Yeah, it's like. What are you doing with your shoulders? He's propulsing them. It's how much you go up.

Okay. I'm going to jump to this question because it doesn't make sense. What are propellants and are they liquid or solid? Repellents? Propellants. Propellants are whatever Cologne Jack is. Propellants. Propellants or whatever cologne Jack is. Propellants. What are propellants?

Are they liquid or solid? They are liquid. What are they? They're the fuel that goes into the engine to make it go up. Okay. When scientists are speaking about propulsion, what does V stand for? V?

V. V means the. V like Victor. The letter V. Vel the letter v velocity okay what is thrust oh no no thrust is when you go up again what are payloads um it's what you get paid when you're rocket science. Look at fucking Calvin. Look at him living it up. You want me to ask you more questions?

Very good. What is an orbital period? It's once a month. Once a month, you got to put a towel down. How does a rocket stay in orbit? There's no gravity up there, man. They're in space, dude. How the fuck do you think it stays in orbit? There's no gravity up there, man. They're in space, dude.

How the fuck do you think it stays in orbit? I don't know. Just put the question back on. It goes up into space. It floats around a bit, man. Who is, I don't know if I'm saying this right.

Laker. Is that how you say it? Laker. Laker. L-A-I-K-A. Laker Watiki. Maybe. Great director. Yeah. Thor. Yeah.-A. Laker Waitiki. Maybe. Great director.

Yeah, he did Thor. Yeah. Laker. Laker's the godfather of rocket propulsion, and he invented the sim tech mode. What are rockets made out of? Oh, metal. Not wood. Not wood is a good answer.

Not wood. There'd be some rubber seals in there that would be special nasa stuff that's why the rockets on the challenger the seals weren't right and the temperature was too cold okay we got a couple questions i just got a point i just got a couple questions left here um for a rocket to leave the gravitational pool of earth it needs to reach a very special speed once it reaches this speed the gravity of the earth can no longer pull it back and it can boldly go off into space

what term is used to describe this special speed terminal velocity that sounds right that was a movie in 1977 two identical space probes were launched, which are now the farthest away from Earth that man-made objects have ever gone. What are they called?

Hubble and Bubble. Last question. What is the difference between a rocket motor and a rocket engine? A rocket motor is just a jet type of propulsion engine. And a rocket engine, like a jet and a rocket engine involves moving parts. Okay. Hey, Calvin, how did Jim do? Zero through 10, 10's the best.

Pretty good. You know, I'd give him probably like a six and a half out of ten that's really good he's in the right ballpark so I feel like there's a lot of half credit here well I don't want to ride in any rockets you make then

my brother it's very hard when you get asked these questions because you don't need to know all this stuff you don't need to know it you got Calvin to know it and I know about other things that are useless. But my brother always goes, I can't believe how little you know.

I'm going to go to the book. And Forrest always rolls his eyes at me like I'm a moron. And it's like it's hard. That's a lot of pressure. Did you know all these answers? I said it out loud. I said I didn't know most of these. So, I mean, I don't claim to know these,

but it's not my job on this show to know these. No, but I... I know everything about the North Sydney Bays from 1990 to 1994. Great. Okay, so... Very specific. I asked Jim what the definition of a rocket is,

and he goes... We didn't grade them. Oh, I'm sorry. Yeah. Oh, yeah. We still got to go, right? What do you get for confidence? My bad.

I'm going to give him a six for confidence. I don't know how to do this show anymore. I'm just going to make you yell at him, John. Whatever score we need for you to be able to yell at him. Completely off the rails. I feel bad. What is the definition of a rocket? Jim said a rocket needs that propulsion that shoots it upwards into the air and involves gasoline or fuel.

So you probably got a point there because you're being nice right yeah i i thought he was pretty close um because a rocket is really just anything that uses combustion in order to go up like it's very broad and open of what's kind of considered rocket because rockets can be like you know these little tiny things you can buy from the hobby store or they can be these massive things that can take you to mars so it's it's a pretty big scale what you can call it so you know those pranks when people like sit on a chair and then the chair explodes and they fly up would that be considered a rocket no that is that's not a rocket damn i used to make those rockets when i was a kid you made them out of there was like a tube and there was like a little engine like a little and then you'd have to put these balsa

wood, you'd have to glue the little fins or whatever on there. And I'd always do mine wrong. It always goes straight in the ground. And I kept doing them. Did you have those in Australia when you build the rockets? No. You're missing out. Find that on Amazon.

Not with guns, you end with rockets. What are rockets used for, for fun to bomb other countries to get up into space. And he said, that's going to be controversial missile and rockets. I don't know. What side do you land on? Missile rockets.

I believe that the missile now is a rocket. Yeah. I, you know, it just kind of depends on, on what planet it lands on. No. It was the intention.

I think a missile is probably a kind of rocket, but when you're talking about rockets, it's probably kind of exclusive from that term. Yeah, but you could work, like, on the dark side, couldn't you? Like, I know you're doing spacey type shit, but if they offered you more money, you could do that. If Putin called you, you could help.

We do call it selling out in my field if you work for the defense industry. But you said rockets have to go up, so there could be a missile on a plane going down, right? Yeah. I mean, a missile does start going up at first.

So it's like all missiles are rockets, not all rockets are missiles. If I hold a firework and light it and I'm holding it upside down, it shoots down the ground. Is that still a rocket? Well, the intention. I think there's an intention. User error. Intent matters.

Yeah, user error. So rockets are used for fun? What are they used for? So rockets can be for fun. You know, I mean, just like you were talking about, you can build like the little hobby rockets, and that's still considered a rocket. If you want to make money building rockets,

you can use them to go up to the edge of space and just kind of like touch there for half a second before it falls back down. Or you can send stuff into orbit, which requires a much larger rocket. Or, you know, go to space. Can you get things delivered by or the drones? Like, do you look at drone technology and think, oh, that's all flashy? I like to have a rocket that's really, you can't control a package delivered by a rocket.

I would love to see a point-to-point delivery for cargo using rockets. The Air Force has given a lot of money to concepts to deliver stuff like that across the globe using rocket technology.

It'll probably be used. Yeah. That would be interesting. Stoops spilled everywhere. It's really hard to convince other cities to let you land a rocket. You know, Houston would be up for it, right?

You can do it at Houston. For a celebration after a basketball game. Well, they've got NASA there. They've got rockets there. They've got the Houston rockets. Calvin's in Austin, so he could shoot one over to Houston. Yeah, he could shoot one over to Houston. Houston would dig it. The whole thing.

Yeah, because I remember when the SpaceX launched here, we remember in the sky it was like, we were being attacked. No one told us about SpaceX. There should have been more going on with that. Some flyers on telephone poles? Yeah, just like, you know, we hear that warning on your phone, some kid's been kidnapped.

You know, good, the AMBA alerts. Give me an AMBA alert for a rocket so I don't fucking think that they're Koreans. It was right at the height of North Korea threatening to bomb us and we just saw a rocket in space like going like that. So it's done done no one told anything oh elon musk is dicking around oh okay i didn't know he was dicking around today i'll stop freaking out um what is a rocket science what is rocket science's proper name jim said aeronautical

interspace propulsion you know you were so close with the aeronautical uh so i feel like i gave you like half a point for that astronautical engineering is the is the like really specific like if you want to be nitpicky about it that's like probably the proper term so what's better like general terms like aerospace engineering what's the degree you have to get uh aerospace engineering usually covers uh covers most of it and then once you get into aerospace engineering you kind of deviate between aeronautical which is like the planes and drones and there's astronautical which is spacecraft and rockets

oh okay where and when did rockets originate Jim said something with the Russians they taped a chimp to the side of it or ancient aliens came down you know what he's talking about Nazis so we kind of credit the first rockets from the Chinese back in like 1180.

They're good at inventing shit, aren't they? This, the virus. 1100? Yeah, we give them the credit for that because they invented fireworks and fireworks is essentially a rocket because it's using solid fuel in order to go up. The first rocket was just like five men standing underneath it with sticks making it pop up and down.

They had fireworks in 1100? They did, yeah. The Chinese had fireworks for a very long time. How else would they celebrate the 4th of July? Oh, yeah. But the first liquid rocket didn't show up until about the 1920s with robert goddard and then the germans built the first like big rocket that actually well that's more of a missile but the first the first uh rocket during like world war ii was considered the v2 and that was

built by you did mention nazis so the the Nazis always come out with shit, man. Did you? Like when there was that weapon of mass destruction, they kept on showing us like just pictures of Saddam Hussein like he was putting together IKEA furniture all around him. Like, don't make me put this together. Like that. And then it turned out there was nothing.

And then you see like North Korea has those rockets that I think are just hollow that they put on the back of a truck and just drive around. Are they real? The ones that we see in North Korea that are on the back. They launch rockets. They launch them into the. I feel like they show us a couple of hollow ones. No, but they launch them into the sea there all the time.

I was doing like tests. Some of them could be fake. All right. So Superman 4, right, where Christopher Reeve as Superman decides to rid the world of nuclear weapons, right? And so he's getting all the rockets. You've seen the film and he gets a big net into space.

He puts him in a net, yeah. Yeah, he puts him in a net and he spins him all around and he throws him into the sun and that makes a guy that's more powerful than him, like it was a bad move, right? But it seemed like in that film that people were shooting these nuclear weapons all the time and Superman had to intercept one like one every day and is that happening no that's not happening okay good good good which is good what a relief so fireworks are relevant because of the chinese that they invented them first that's what we're talking

about yeah yeah they uh that's a specific type of rocket called a solid rocket um propellant have you seen superman 4 uh yeah i've seen it yeah you have to see that one i had a blonde guy that i bet you he fucking rakes it in at comic-con that can't the guy he was the villain the flaming guy yeah he had like two words how did he turn into a villain again um what they did was they put a bit of his DNA that they got from a museum. They got a bit of Superman's hair and they cut the DNA. Lex Luthor comes in and cuts the DNA. He does it with the guy out of Two and a Half Guys.

Two and a Half Men? Two and a Half Men, yeah, Two and a Half Men. John Cryer? John Cryer plays Lex Luthor's nephew. And he's like a Californian, like, whoa, uncle, what are we doing? Oh, my God. And then he gets, like, the hair and he puts it in a box and he sends it just to fucking the sun.

I can't remember. There's a bit. There's a whole other story there. I don't know how, but Lex Luthor gets a little outfit, a little tiny doll's outfit and a strand of Superman's hair into a box, and somehow, this is the bit where I'm missing, somehow he gets that to the sun. So you just have to, that's just happened.

It's just sitting in the sun. Okay. And then Christopher Reeve's Superman, right, he collects maybe 70 nuclear weapons in a net, and then he swings them like the Olympic hammer, and he throws them into the sun, and then he swings them like the Olympic hammer and he throws them into the sun and then that explodes making a chain reaction where the hair from Superman

fuses with a little outfit that hasn't burned up yet and it makes a guy and he's like flame guy and he just goes flies down to earth. Isaac Newton came up with three laws that govern our world. These laws are the laws of laws of what you said relativity being nice to each other and

something else um i don't know so what what are we doing the laws of motion the three laws of motion motion and what are those three laws of motion more cushion for the pushing that would be one of them the first one is essentially slap and ride the wave the first one so the first one's like object in motion stage in motion the second one is force is equal to mass times acceleration and the third one is every action has an equal and opposite reaction so what goes up must come down i was pretty close on that one. It's kind of. The concept. The concept's there. Yeah.

Is that true, though? Because I feel like you put things into space and they never come back down. Not necessarily. You can't. So this actually goes to one of the other questions about what that special term was called, if you can go fast enough. The special speed. He said it was terminal velocity uh not terminal velocity escape velocity so you can you can if you go fast enough the you

the earth can't you're going too fast that the gravity uh can't really affect you anymore you just leave the sphere of influence of of earth so it's one of our problems with visiting other other planets that have more gravity like i believe jupiter has more gravity right because it's big or some shit right and so so we can't could you get a rock rocket to take off again from jupiter or would you be out there stuck in that gravity well any you can design anything uh but can you do it well technically no if you want to be like very specific jupiter's actually a giant ball of gas so like you can't actually like you know land or take off from jupiter well not without a jude no but i've it would be very difficult to try and

build a rocket to do that i would wager probably not possible with today's technology to leave that gravity well if you were just like sitting on the surface do you believe aliens are involved with that technology in any way no i do not i thought we had an expert um what's the difference between velocity and acceleration? Jim said acceleration is how much you're ramping up. Velocity is the G-force coming back at you. So velocity is how fast your position changes. And acceleration is how fast your velocity changes. You actually had it mixed up.

The acceleration is that G-force that people are talking about. Like that. Because you can be in a train. the train is going to be going you know i don't know 60 miles an hour but you don't feel any force it's like it's like a normal day for you sitting in the train yeah because it's going at a constant speed but as soon as the train starts changing its velocity to stop suddenly you're going to be like jerked forward because that's that's an acceleration on you i always think that with roller coasters it's like they should stop telling us how many miles it gets up to.

Like you're in the line, they go, this roller coaster hits 67 miles an hour. And I'm sitting next to me, son. I went, we came here faster in the car. Yeah, they should tell you the G-forces. Yeah, the G-forces. I'm like, oh, I'm going 60 miles an hour. I'm like, woo-hoo.

Going to 80 down, yeah. Yeah, the G-Force is like, I'm like, oh, I'm going 60 miles an hour. I'm like, woo-hoo. Going 80 down the five. Okay, so I asked Jim how fast rockets go. He said first stage, 700 miles an hour. Second stage, 1,000 miles per hour. So, no. You're really low. This first stage. I'm talking about the original rocket.

In 1,100. Well, if you're trying to go to space, which you have to go very fast in order to get. this first stage. I'm talking about the original rocket. In 1100. If you're trying to go to space, which you have to go very fast in order to get into orbit. The first stage has to go about like 6,000 miles an hour and it'll detach from the second stage. And then the second stage will ignite and keep going. And that second stage at its max speed to get into orbit is going to be like 17,000 miles an hour.

That's really fast. Yeah, you're right here, Mach 22, 22 times the speed of sound. How long does it take for the astronauts to get used to that? Because you see them in movies. How long does it take? Do they ever hit like that train? How does their body not just collapse so there's we we rate rockets uh human rated rockets are a special type of thing that you do

because we're not some rockets that just send the probes up like we we can exert g's onto those spacecraft up to like you know six maybe 10 g's and it's that's fine but you don't really want to put a rocket under or a person under you know six to ten g's and it's that's fine but you don't really want to put a rocket under or a person under you know six to ten g's you want to keep that lower where the acceleration isn't nearly as harsh so they're closer to maybe four to max six so they're not they're just being pushed into their seat but they're not going to black out from it you know because i just saw top gun they black out out at what? 10, 10 G's. Yeah.

I'm like nine or 10. I don't know. I would just think your bones would collapse. I'm like, like your organs would explode from compression. Well, you sit, uh,

the way you sit a rocket, you actually, your back is, you're basically facing straight forward. And it's not like you're, you're sitting in a chair and you're going up. You're actually like straight forward and it's not like you're you're sitting in a chair and you're going up you're actually like laying down and going oh yeah so all of that force is on your chest which you can handle a lot better than if it's like coming down okay that makes

sense could you eat while you're doing that could you put food in your mouth uh no it would it would be very uncomfortable i mean like your arm weighs six times more than it normally does. So that's really hard to move. Jax just lifted up his arm to Wyatt. He's like, I'll use this six times more than this. There's actually a great scene in First Man where Ryan Gosling, they go up in space and their spacecraft starts spinning out of control and it keeps spinning faster and faster

and you end up exceeding a crazy amount of Gs and he's barely lifting his hand and it just flies backwards because of how many Gs is being pulled while it's spinning out of control. The guy to his right ended up passing out and he had to figure out how to stop it is being pulled while it's spinning out of control. The guy to his right ended up passing out, and he had to figure out how to stop it so they didn't pass out and die in space.

Oh, so passing out is not ideal. I would rather pass out just to miss the stop, but then you die. This is a quick one. You mentioned the trains before. I've heard this theory that, like, okay, so if you're walking on a train and the train's going 300 miles, right, you're on a bullet train, and then you're walking along at, say, four miles an hour, an average sort of walking speed, I reckon you're going 304 miles an hour.

People go, no, you're not. You're still going the same as the train. But I am. I'm getting to the front of the train. Oh, like on an airplane too. Yeah, yeah, yeah. I believe I'm faster than the airplane then, but they tell me I'm not. No, that is correct. You are going 304 miles an hour yeah yeah that's it i had this debate because people go but when you jump the train doesn't like go underneath your feet i understand

that i'm not saying that's going to happen i'm not stupid i'm just saying that i move faster than a train yeah that's true when you're in an airplane you go you're walking from the bathroom from the back you know 500 and okay i'm flash idk what is propulsion jim said how much you go up no you want to rethink that six and a half points well propulsion is is more about it's honestly just the engineering of how you can make force to make something go up. And that can happen a lot of ways. I mean, propulsion isn't just like rocket engines.

It's also airplane propellers and jet engines. That's also in the realm of propulsion. Okay, so I'm acting like I understand what you're saying. Okay, so you're saying that we have to get to a certain speed to be able to get into outer space. Does the gravity get more aggressive as we go up? Because, like, why can't a helicopter just gradually go up and gradually go up and gradually, and I'm in space.

Well, that's a great, so that goes back to how do rockets actually stay in orbit, and this actually goes back to a thought experiment that Newton had. And if you were to have a cannon sitting on top of a mountain and you fire the cannon, like say really slow, it just kind of comes out and falls in the ground like you expect. But the earth is actually curved. So you can fire this cannon fast enough that by the time it tries to reach the ground,

the earth has already curved away from it and it'll just like fall perpetually forever in a circle and that is what orbit is it's just going fast enough where the earth curves away from you by the time you reach it okay so i think i've been telling my son some bullshit right um but i okay so you're flying, say like I'm going flying from Sydney to LA, the flight's shorter than LA to Sydney. It's longer that way. And people say it's jet streams, but isn't it just that I'm flying against the spin of the earth.

So I cut off an hour. You know, I thought this too, and I've wondered this is sometimes that is true, but I've actually had some of my flights where i'm flying with the or against the speed of the spin of the earth where it's actually longer and it is more dictated by the jet streams than it is by the spin but it is an effect are we going against the spin of the earth or we always stay in that atmosphere flying i think it's the same reason if you jump in an airplane you don't go flying back because you're still in the earth but you're the winds are dictating i told my son this with a lot of confidence okay well there's a rocket scientist and he's not quite sure like but then there's

jet streams or something you need a meteorologist in for that jet stream stuff yeah yeah why can't i just jump and the earth moves underneath me and i'll land back down and that's jumping until you jump in well because when you jump initially you you're you still have the same velocity i know why i know when the world's spinning why am i going how fast are we spinning uh what 24 hours a day you know yeah i, but how fast is it? It's like 30,000 miles an hour or something. It's fast. It depends on where you're at too, right? You're spinning faster at the equator than you are at the poles.

The pole's at zero. Oh, the poles aren't spinning at all, man. Oh, that's why Santa's never dizzy. Which actually helps you. When you're trying to launch a rocket, it is always better to be, one, close to the equator, and two, launching to the east. Because you have the fastest, you have all that speed at the equator from the earth spinning. And when you launch to the east, you have that velocity added to you from the earth spin.

It's a lot harder and requires a lot more fuel if you try to launch to the west. Because you have to cancel out that velocity of the earth first before you can start working towards getting to orbit so that's why we launch rockets in florida yeah one class of the equator and it's going to the ocean away from people okay and when you launch from the west every time we launch to the west we're almost never going in uh around the equator we actually go above and over the poles because it's easy to do that than it is to try and like cancel out the Earth's velocity so what would be the perfect place like an island on the equator or

something like that oh yeah absolutely that would that's that's pretty much it that's the dream so when you said this about the orbit like it's just it's going fast enough to just keep falling. What's that speed. It has to be at like, uh, that's about, it's about 17,000 miles an hour in order to do that. So that should be an orbit.

You're going 17,000 miles an hour. Yeah. And what's, it gets, it gets tricky because, uh, when you're close to the earth, you actually have to be going faster than if you're farther away.

And it's not because of gravity, really. It's more about if you're so far away from the curvature of the Earth, you don't have to go quite as fast in order to miss it because you're so far away from it. That's why, for example, the ISS is going much faster than the moon because the ISS will go around the earth 90 minutes and one rotation, but the moon takes 27 days. So the farther are you away, the slower you can go for an orbital period. An orbital period is how long it takes for you to complete one orbit. Have you ever worked for one of the billionaires?

No, I've had no i've worked for nasa and i've interacted with those companies but i've not worked for them now why do you think the billionaires want to go up now i know you there might be a future job potential thing so you wouldn't want to i think it's because there comes a point when you have money when you go i've got everything i want i don't want any more things and so you start buying experiences that's the next thing you do with your money i'll do things that experiences because you run out of possessions worldly goods and so i reckon that's why billionaires do this because they're like all right i want an experience that only i can afford yeah it's probably more just to say that they did it. Like less about

even the experience. More like I got to do this thing. It's like if you pay for six or seven prostitutes at once. It's because you can. Right. Not because it's more fun than two prostitutes. Not because you need to. So you go, alright, I've done that. I haven't. Not six. That's silly.

That's too many. I'm not that rich. Okay. So five. What are propellants? The fuel that goes in the engine. And are they liquid or solid? Jim said liquid.

So trick question is actually both. You can have a solid or a liquid propellant. There's so many different kinds. Because the originals were solid you said the fireworks right yeah the fireworks were those were solids we started out with solids for a while before we moved into into liquids but you get so much more efficiency and thrust out of the liquids than you do out of this when you when you have a young new person work for you what idea do they always come in with and you roll your eyes like, oh, God. He's going to come in with graphite tips again.

Fuck, you know. I've heard this. They don't work. They fall off. They can't handle the cold. I hear two that are pretty common. One is the gravity elevator. So you have an elevator that will, you know, take you up into space.

You have a really, really long tether. I hear that one a lot. And that one's like. make that make that make the gravity elevator so it's just a great big tube that goes up and then you get on there and there's an old person on a chair with a stool what floor space yeah it'd be good man you go straight up into space and then you see it and you make it like Charlie and the Chocolate Factory in the glass elevator. And at the end when they're all floating around and all that type of stuff. Always creepy. Why were the grandparents, why was that old cunt in Charlie and the Chocolate Factory going, I can't walk, I can't walk.

Oh, there's a good activity today. Oh, I can walk. What a fucking sneaky prick. But besides that, so the gravity elevator. So am I right, a big tube, this is your idea that you brought to us, right? No, he said this was. Big tube that goes up into the sky.

So you would get on it and then you would just go up into space and then you come back down? Yeah, you make it long enough so that the orbit at the very end of it, the orbit actually matches the rotation of the Earth so you can basically go straight into orbit. But then you just come back down. That's someone that had worked at a bank right before they got to the rocket. Tell me if this is possible. I've heard this theory a lot. So we have like flying from LA to Sydney is 14 hours, right?

But if you fly up into space and then you fly straight back down, we can do it in like an hour. Yeah, that's pretty true. Yeah. So how far away from me for that? Because then I'll never retire from doing stand-up. If I can do that just in the air, straight back down, I'll gig in any city you want.

Yeah, that's true. SpaceX has proposed it yeah they've and they've got a few renderings of them trying to pitch to be able to use rockets do they landed on like the sea barges I think what's more likely to happen first before you see rockets taking people from place to place is probably more like something called a hypersonic or supersonic uh commercial aviation they're bringing back like the concord type of ones right yeah the concord type planes they're talking about that again five times the speed of sound yeah yeah yeah that'll be good see that's the problem

he was saying there was land on a bus seaboard so even though you get there quicker than you'd be on a seaboard you gotta take a ferry no but they'll get the landing technology better they'll figure that out they'll figure that out southwest will know what to, then you'd be in a sea barge. You'd have to take a ferry. No, but they'll get the landing technology better. They'll figure that out. They'll figure that out. Southwest will know what to do. Everyone, you'll be in your zone. Get on your rocket. But the thing is, because it's a rocket,

you all have to be strapped facing upwards. So that fucking air stewardess is sliding down, trying to sell you scratchies. Yeah. The drink cart goes. Kill somebody. What are the propellants that we use, the liquid ones? What are those generally?

The most common ones that are used are, it's going to be kerosene and liquid oxygen. That's probably the most common ones. Kerosene? Yeah, kerosene. We have a special name for it. We call it rocket propellant one, RP1. That's the name we give our special.

You have it in jerry cans at the back here it arrives in on a jeep ever seen those jeeps now where people have the jerry cans on the side the fuel cans it's like really dickhead really yeah you're in a place where i need two lots of fuel because i get so far out there so rp1 is lit kerosene and liquid oxygen? Yeah, yeah. We liquefy the oxygen down so that we can carry more of it. And then we mix them together and throw them out the back end. Okay. What is thrust? Jim said when you go up a gear and then he made a mouth noise.

So thrust is really just about taking mass and throwing it behind you. It doesn't matter what it is. It can be air. It can be rocket propellants. It can be weight balls. It doesn't matter. So when you talk about sex, you read a romantic novel and they go, he thrust it into me.

That's correct. It's mass coming in from behind you. Oh, boy. Yeah. It is, right? By the book. It is a thrust. But you know what it is? It's part of the book. It is a thrust. But you know what it is?

It's like when you're in a swimming pool too and you push the water. I'm just going to PG it up. For the kids. We have two different podcasts. Jim's like anal sex for us. He's like,

when you're swimming in a pool. When a man is. I do anal sex in a pool. Oh. I don't make that mistake three times. Have you ever sat in like an office chair and your buddy also sits in like a rolly office chair and you push off from each other and you both go in the

opposite directions? Yeah, I have fun. You don't talk about it? Yeah. I know what fun is. So if you are the rocket. I imagine you and your mates do that all the time at the rocket thing. There's a lot of pushbacks to the chairs.

I reckon that would be the way to go. I'd do it like Alex P. Keaton in Family Tires when he pushed away from the typewriter in the opening credits and he goes like this. Oh. I miss Family Tires. If you and your friend did that, what were you saying was the example? Oh, yeah. So if you and your friend sit across each other in roller chairs and you both push off at the same time, both of you go in opposite other in opposite directions and you're the in this case you're the rocket your friend is the rocket propellant that's all we're doing is we're just throwing stuff out the back end and if you shove if you throw something out behind you you're going to go in the opposite direction

now tell me if i'm wrong about this because i've watched a couple of little spacey documentaries right so the original rockets on the challenges and and that type of stuff, they were one and dones, right? They just landed in the ocean, they were over, or did you repurpose them? So when NASA was using the space shuttle, they attempted to reuse the white boosters off the side of it. They tried to refurbish those, if I remember correctly, to reuse them.

But for the most part, those orange, big orange can and the two white sides were pretty much one and done. The space shuttle required, even the space shuttle itself, required a lot of refurbishment in order to be reused. It wasn't very sustainable. But it was a Bezos or a Musk. One of these comes back down now, right? Yeah, Elon Musk can land the first stage of the rocket pretty much anywhere

after it's launched, and they've reused them up to maybe 11 or 12 times now. Right. Ask Jim, what are payloads? This is what you get paid when you're a rocket scientist. Yeah, pretty much. I feel like that's so close because This is what you get paid when you're a rocket scientist. Yeah, pretty much. I feel like that's so close because that is how you make money. Payload is the thing you actually put in the rocket that goes to space. And the people who want to send stuff to space pay me to have a ride on my rocket.

And that is what a payload is. And what do people pay you to send into space? What are we sending into space these days? Lots of satellites, a lot of satellites. There's a new one like the Hubble telescope. They reckon they're getting the best images ever that came out a couple of weeks ago. Yeah, it was the James Webb Space Telescope.

That is a payload on a rocket. Is that like light years ahead or, you know what I mean, like people are raving about it or are they just or is it just like beta max versus vhs the james west space telescope is the one of the best it's the best telescope we have out there right now to look back in time uh the astrophysicist guys have come up with a really great technology of looking in the infrared spectrum which is you know it's hot it's like in the hot side of invisible light. And they look out into the far deep space and they can see back

like close to the right to the big bang, which we didn't have before. I've watched a lot of rocket launches on TV, on the news and all that stuff. Whenever it goes successfully, you all start high-fiving each other and hugging. In the movies, there's always a guy with a cigarette who sits there silently and just nods to himself. Right?

Does that go on and you guys get fucked up drunk after a successful launch? Yeah. You should. All right. Yeah. And that's why we can't land them. That's someone else's problem. That's Monday's issue.

With the payloads, is there anyone that ever comes to you and they're like, hey, I got a package, but you can't ask what's in it? It's like the missing ballots from the 2020 election. They're just floating. Don't worry about what's in it. Just put it in there. There are defense launches that are top secret that

you can't know what it's for, but you know what it's for but you know where it's supposed to go so you could be evil what's the weirdest thing that you've sent up into space that you're allowed to tell us about um man i don't know weirdest but i felt really bad on our we we put some children's drawings on the first rocket we launched and it blew up. Look, I'll tell you what. Don't feel fucking bad about that. Don't feel bad about that. They bring them to you every fucking day. And they're all not fridge worthy.

Some of them are good and then other ones you're like, this one's not up to the scratch. That's funny that if it was the parents were like, which ones do you want to send up? Send up the shitty ones. Oh, no. My ex kept every single thing, every doodle that Hank ever fucking drew. I kept like five or six like sort of stellar ones.

Yeah. You frame those? He's not bad at drawing, my son. Yeah, he can draw. He draws animals real good. What is an orbital period? Jim said once a month you got to put a towel down. I think that's wrong.

Yeah, underneath the rocket so you can fuck it. Oh, my God. An orbital period is how long it takes to complete one orbit around whatever you're orbiting. It can be the Earth. It can be the moon. It can be the sun. Like the Earth has an orbital period of 365 days around the sun. The moon has an orbital period of 27 days around the Earth.

The ISS has a 90- of 27 days around the earth. The ISS has a 90 minute orbital period around the earth. So it's just how long it takes to complete one orbit. What is the next big breakthrough that you're all working on now that you think is going to be a game changer? Nuclear thermal propulsion. Tell us about it. That's the exciting one. That is,

so it sounds really spicy. How it works is you, instead of having a chemical reaction where you're burning, like, cause what we typically do is when we have a rocket engine and you have this chamber and then you insert the kerosene and liquid oxygen, and then it creates a big flame and then you shove it out the back end through the nozzle. Instead of having combustion, the concept is to replace the combustion part with a nuclear reactor, and the nuclear reactor generates that heat.

And then all you have to do is take hydrogen, run it through the nuclear reactor, absorb all that heat, and then put it into the nozzle and shove it out the back end so you get all the heat from the reactor instead of combustion. And you're getting pushed back because of the word nuclear in there? It is difficult to try and test nuclear things on Earth, yeah. In Australia, we should have nuclear energy because we have uranium, like tons and tons of people, and it's a clean sort of type of energy, but people are very resistant

and they'll stick with coal because they don't like that word. So why don't you just get rid of that word and call it like, that's what I always thought about the vaccine. Just call it the COVID shot because the flu shot is a vaccine, but no one gets worried about it because it's just called the shot. So just don't call it the nuclear reaction thing. Call it the boom, boom jet plane or something like that. You can toy around with names.

You don't have to land on that. Boom, boom jet works good. Boom, boom jet. Boom, boom fuel. Boom, boom fuel. Yeah, yeah. Boom, boom, boom. Boom, boom propulsion.

There is a treaty that's kind of sitting around right now where our countries, like Russia, the US, China, we've all signed this treaty that says you can't test nukes in space. And under that umbrella also kind of encompasses this nuclear thermal propulsion concept too. So we can't even do that right now either. So we're kind of trying to change that. Oh, they're so bad to have a treaty.

Oh, I missed one. They do more harm than good the treaties i missed the question when scientists are speaking about propulsion what does the v stand for v so there's two it's velocity you had it correct give them what they want there's two there's two velocities that we really care about when we're talking about like rockets one of them is the velocity that the actual gas is leaving the rocket engine. How fast is the flamey part going? That's one of the Vs that we care about. The other V that's really important

is the velocity change required when you're in space to go from point A to point B. That is the other big one. Do you guys have merch? Merch? Yeah, like do you have merchandise? NASA does. Yeah, NASA has rocket merch.

You mean with the company he works for? Yeah, do you have hats and stuff? Yeah. Firefly Aerospace? Yes, there was. We changed our website recently, but we should still have a merch store on there. I'll check it out.

We talked about how Rocket stays in orbit. Who is Laika? And you said the godfather of rocket propulsion. Yeah. No. But Laika was the first animal

that was ever sent to space. The Russians sent this dog. Her name was Neda. Into space. And she overheated and died. Oh no. Wow. You don't leave them with the windows done up. You don't leave them with the windows done up. That'll happen every time.

We know that now. That was the 60s. That's how it was. Actually, this was like 1957. That was 1957. Elvis was in the charts. I mean, it was a different time. He probably didn't even have a seatbelt.

Oh, my God. Poor guy. It took a while for them to send a person after that. It wasn't until like 1961 before they sent the first person into space. Speaking of which. Yuri Geller. You're close. Yuri Gagarin.

Yuri Gagalin. That's his name. Yuri Geller's the guy who bit the spooch. I went on your guy's website to see if there's merch, but I did find that it just says, book a ride. So you can just book a ride? You can. If you have the money, you can book a ride.

How much is it? How much to go into space? I think we're selling them for like $12 million or $15 million. You almost had me. I thought you were going to say $12,000. I think we're selling them for like 12 million or 15 million You almost had me I thought you were going to say 12,000 12,000? I'll give you 12 bucks

We bar it We meet in the middle somewhere I go low, you go high, and then we go back and forth What are rockets made out of? Jim said, not wood. Not wood. Rubber seals.

Not wood. Funnily enough, there is a wood rocket. Oh God. Yeah. And pretty much everyone uses this cork. And cork is wood. It's bark from a tree.

But cork is used to insulate the rocket. And a lot of people use cork in order to insulate rockets. Doesn't burn up? Rockets are actually made from lots of different stuff. It's good to leave pistons on as well. Most of it's aluminum. A lot of the times people make rockets out of aluminum. Most recently, people have started making them out of carbon fiber

and having no aluminum pretty much on the rocket body at all. Um, some of them use stainless steel, like a SpaceX is new starship rocket. Um, and the engines will have like crazy, uh, materials like niobium and molybdenum and copper,

copper, copper, lots of copper. The actual, most of the engines are, are formed with copper on the inside, and then you put nickel on the outside. And the rest is aluminium foil.

And vibranium. Niobium sounds like a word you would make up if you didn't know the answer. It's made out of niobium. You didn't know that? Idiot. In 1977, two identical space probes were launched, which are now the farthest away from Earth. That man-made objects are gone. what are they called Jim said Hubble and Bubble

it was Voyager 1 and Voyager 2 you guys got to come up with better names Voyager and the second the second one I'm not blaming you in particular but Voyager 1 Voyager 2 we'll call it Voyager 2 the return Return, or this time it's personal.

Say something like that at the end. A real sequel. Yeah. That's the name of the rocket. Yeah, you go Voyager 2. You made me mad. Yeah, they're sitting out in, like, interstellar space now, not even inside of our solar system anymore.

Oh, yeah. With George Clooney. I'm looking at your rockets pretty good all right um i don't know it looks like a rocket so it looks good what is the difference between a rocket motor and rocket engine so the engine involves moving parts motor is jet propulsion or something you know i i i loved this answer because it was so close uh the rocket motor we kind of classify as anything that's solid propellant, a solid-only propellant engine,

so it doesn't really have any moving parts. A rocket engine is usually when it evolves liquids, and it does have moving parts when it's involving liquid propellants. I thought that was a great answer. That was the last question.

You did pretty good. In your offices, are there any mice doing anything? Mice? Yeah. You're testing on one or is there one that you're making go through on May? I feel like all scientists have a mice doing something.

That's silly. You don't do any animal testing. You don't do any animal testing tell that to the fucking dog I have a question if somebody has 12 million dollars and they go up in a rocket how do they get back very carefully you can actually wait

another 12 you can wait long enough when you're in orbit if you're close to the earth if you're at the ISS level you can wait long enough when you're in orbit. If you're close to the earth, like say if you're at kind of like the ISS level, you can wait long enough and there's actually enough air there. It's very little, but there is enough that after a long period of time, you could just fall back. But most of the time, we just fire some rocket engines to slow us down

to get us to come back and hit the curvature of the earth. Do you have a pilot with you when you do that? Or are the people upstairs, like if you take your bird up there, if you take a girl up there, can you turn off the camera and, you know, jiggy, jiggy, jiggy? Or do you get any privacy is what I'm asking. Is there a curtain? Where do you poo?

On the ISS, there is privacy to sleep and to use the restroom. As far as NASA has said, no one has had private time. Not even a solo. The bloke hasn't gone to knock one off in the bathroom and what she's come all good. I remember there was a poem when I was a kid. It was with Sylvia Saint, right? She was one of me faves from Europe.

And there was one in space and it had an anti-gravity ejaculation. It was one of those ones where they fly the planes up and they drop them all the time. That'd be the only reason to make that porn would be because of that. Yeah, yeah, yeah. And the guy had to come because you only get like 10 seconds of that drop time where you have the no gravity. It looked awesome, man. It's well worth a watch, yeah. And the guy had to come because you only get like 10 seconds of that drop time where you have the no gravity. It looked awesome, man. It's well worth a watch, man.

Yeah, that would be the thing too. It would be like the – I guess if you're just going up in a rocket, you've got to use the bathroom before you go up. How many years of school do you have? How long did you go to school? Seven. Now you're talking about me ejaculating on planes. I'm sorry, mate.

I'm sorry. I brought the whole conversation. That's a low point. Okay. This is the part of the show called Dinner Party Facts. I asked our expert to give us one obscure, interesting fact that onions can use to impress people. What do you got, Calvin?

So, actually, I asked some of my friends this because I was looking for a really good one. And this is really interesting, one of my friends this because I was looking for a really good one. And this is really interesting. One of my friends brought up. If you compare the weight of an empty soda can to the weight of a full soda can and divide those two weights, you get the exact same number. If you were to divide the empty weight of the space shuttle tank to the full of propellant mass of the spatial tank. And it's based,

that's, it's an example of like how little and how massless the. Most of its fuel in there. Yeah. It's gotta be so thin then just the wall of the, it's just like, yeah. Cause even the soda can. So that's so to be so thin then. Just the wall of the... Yeah, because even the soda can. So that's so light once you drink all the soda. Like shotgun or rocket.

Wow. Pop a little key. It's got to be really thin. It's uncomfortable. You were talking about coming in space. No, Kelly, no. It was respectfully done. I'm known for these things.

You're better than this. Oh. All right, Calvin, well, thanks. Arnie's going to console him. You can find Calvin on Twitter at Cal D Phillips Jr. C-A-L-D-P-H-I-L-I-P-S-J-R. If you want to get a ride on a rocket,

$12 million, sign up on the website. Love it. Is there anything else you want to promote or say? Calvin, thank you for being here. Yeah, I appreciate it. I love rockets. I spend all day thinking about rocket propulsion, so it's fun to talk about it. Calvin, you're a good sport, mate.

Thanks for being on the podcast. We learn stuff. Sometimes on this podcast, people tell us stuff and we act like we're taking it in. We don't take any of it in. And I took several of these moments in. I know more about rockets now than I ever did before. So Calvin Phillips, thank you very much for that. If you're ever at a party and someone comes up to you and goes,

I reckon this Coke can weighs more than a rocket, I don't know about that. You didn't learn anything. Yeah, I don't know about that. You didn't learn anything. Yeah, I didn't learn anything. Good night, Australia.
