Laura: Hello and welcome to another episode of Lex Education, the comedy science podcast, where comedian me, Laura Lex tries to learn science from her normal brother, Ron.
Ron: Hello, I'm Ron.
Laura: Hi, Ron.
Laura: You're so normal.
Ron: I'm very normal.
Laura: Same room episode?
Ron: Same room episode.
Ron: Attic record.
Laura: That so close to each other warming.
Laura: It is.
Laura: Do you want to open the window?
Dara: Yes.
Laura: Yeah.
Laura: Okay.
Laura: We're sharing headphones because it's a special episode today.
Laura: It's our first ever guest episode.
Laura: We've never had a guest before.
Ron: We're not going to top this, so we'll probably not have another one.
Laura: I imagine he's excited to be here, too.
Laura: This will probably be the most exciting science project he's ever been involved in.
Laura: We would love to introduce you is our substitute teacher for the day.
Laura: It's none other I don't know how he's here.
Laura: It's darrow brian.
Dara: Hello, everybody.
Dara: How are you?
Dara: Am I really his first guest?
Laura: Yeah.
Dara: Do you want me to get you some guests?
Dara: I'll put a call around and you'll be like David Attenborough tapping in the glass.
Dara: What is this kind of a thing?
Dara: Yeah, absolutely.
Dara: I was threatened by David Attenborough.
Dara: This is my favourite nerdy story of all time.
Dara: I was UN threatened by David Attenborough.
Dara: What?
Dara: I've written a kids book about science and it mentioned animals in passing.
Dara: I'm standing waiting to do an interview about it, like pre Christmas in that there's a part of Radio Two where you wait before you do all the shows.
Dara: And David Attenborough came in, he was obviously on after me or on a different show or whatever, and I sat down, I've met him a couple of times and I said, David, how are you?
Dara: Chatty, chat.
Dara: And then I said, David, I should tell you this, I've written a book and I do mention animals in the book.
Dara: And David Attenborough leaned in and went, you get space.
Dara: And I've taken I've taken to be totally that he's he meant that totally.
Dara: Like, I say, hey, back off.
Dara: This my this is my world.
Dara: He'll step in on animals without really putting the time in.
Laura: Do you stand a bit taller that day?
Laura: Like, David Attenborough was a little bit threatened by me.
Dara: I did bance with attenborough.
Dara: You know what I mean?
Dara: It was lovely.
Dara: So, look, I'm deeply flattered to have been invited.
Laura: You should be so depressed that you're here.
Dara: Honestly, it's lovely to I did nothing I like more of an evening than talking about science.
Dara: But I'm also aware of your general antipathy towards the beautiful science.
Dara: The beautiful science that is physics that you just don't you're not going for it.
Dara: You're not going for it all, are you?
Laura: I think it's stupid.
Laura: I think it's very much giving maths sums to things that were happening anyway, that we've just been covering.
Laura: Scalars and vectors.
Laura: Ron assures me it's the basis of how everything works.
Ron: A friend of mine actually texted me a quote from this week's episode.
Ron: It's just useless.
Ron: It's intellectualism for the sake of it.
Laura: It's your description of physics, because we had to work out how long it took me to do a journey I didn't do.
Dara: Yeah.
Dara: Have you never had a hypothetical comedy routine?
Dara: Have you ever spoken about that's?
Laura: Got a purpose that makes people laugh?
Laura: This was just sad.
Dara: All it is is a lot of it's training.
Dara: A lot of it's training for a thing you will never do.
Dara: Look, I get it.
Dara: A lot of math for people who don't go on to use it is like doing star jumps and then wondering where all the star jumps in adult life.
Dara: I did so many star jumps in school, it's amazing.
Dara: Adult life didn't seem to involve running around a field.
Dara: But people don't quit it because people get the point of doing star jumps just as a general health thing.
Dara: So I'm afraid Scalars and Vectors are just a general health thing.
Dara: Your brain, despite you, has become slightly more ripped because you now know this.
Dara: In Scalars and Vectors, I think it's.
Laura: Curdled.
Dara: You do know the difference, that one is just a number.
Laura: They're both just numbers, dara.
Dara: They're really not both just numbers.
Dara: Right.
Dara: It's a number and an extra bit.
Dara: It's like a two dimensional number because it has another piece of information contained within it.
Dara: One is just a number.
Dara: One is just a thing, like, whatever, how tall are you?
Dara: But the other one is the other.
Laura: One is how tall would you be if you'd bent over and wandered away?
Dara: How long are you and in what direction?
Dara: The other had the second thing attitude as well.
Laura: I just feel like only the one that is where you actually got to.
Laura: That's the only one that matters.
Dara: Are you still on the train journey that you'd never made, that we worked at, how long it took you to?
Dara: Is that so?
Laura: Well, like, you know, if I'm 200 miles away, that that matters.
Laura: It doesn't matter whether the M 40 was a longer journey than the M one.
Dara: Yeah, but hang on, it surely matters which direction you're 200 away is in.
Laura: Oh, that depends.
Dara: If you were leaving London and the gig was in Woking and you end up in Seven Oaks, then the second part of the vector, the direction part of it, is really, really important as well.
Laura: Not every what was the other bit that was like that was the journey.
Laura: Even though you went to Woking, sometimes you were listen, but one was the.
Ron: Distance you travelled and one was your displacement from where you started.
Ron: And I tried to turn it into a fun little story where we got.
Dara: Pyella on the way, but I can kind of see where that was difficult.
Dara: For example for example, at some point you're going to talk about orbits, presumably, because this is space, right?
Dara: You're going to talk about orbits.
Dara: Right.
Dara: And do you understand what an orbit is.
Laura: The chewing gum?
Dara: No, not the chewing gum.
Dara: The thing from which the chewing gum took its name.
Dara: Very important to get with the order of these.
Dara: Correct.
Dara: Right.
Dara: However, this is often tricky.
Dara: Pluto isn't named after the cartoon dog.
Dara: Pluto is named first.
Dara: Pluto actually is a Greek thing.
Dara: And it was a ten year old girl who won and she won a five pound note for coming up with the name of Pluto.
Dara: They had a public competition.
Dara: Yeah.
Dara: And so she came up with the name because they discovered Pluto, they saw doing its thing, or they saw reverbing things around it and found and told look and saw Pluto for the first time.
Dara: Huge thing, 1930s.
Dara: So people hadn't discovered anything in about 100 years.
Dara: Another planet in about 100 years.
Dara: And so they had an international competition and some girl came up with the.
Laura: Name Pluto, but then it isn't a.
Dara: Planet now, because it turns out it doesn't do enough.
Laura: This is one of my questions.
Dara: Yeah.
Laura: And I checked with Ron whether this was a stupid question beforehand.
Laura: What is a planet and why isn't the moon a planet?
Dara: Because we just keep the word planet, obviously.
Dara: Look, they're all big lump.
Dara: They're all big, round lumps in space, right?
Dara: In that regard, you can stick them together, right?
Dara: What matters is how kind of strong and independent it is, is really what we're talking about.
Dara: We keep planets for things that because if you imagine it all started with a big cloud of dust, right?
Dara: All these things are made by clouds of dust.
Dara: And what happens is gravity kind of begins to swirl them and swirl them and they sing as begin stick together and they clump.
Dara: Clumping is the most important word in astronomy.
Dara: Clumping.
Dara: Bits of it just kind of bump together.
Dara: Clump together.
Laura: You see what I mean now about them just making stuff up.
Dara: If you want to understand astronomy.
Dara: Do you remember when you took a poster off a wall and there's bits of blue tack and you used a big bit of blue tack to pick up the smaller bits of blue tack, right?
Dara: That space.
Dara: Everything in space is actually so bits of things clump other bits of them together, right?
Dara: Usually in the middle of it, there'll be a huge one, which will be a star, because a star is basically loads of dust and gases.
Dara: Gases basically pulled together, and then they squish, and it gets so big, it squishes stuff in the middle and it forces them together, and that explodes and it creates all these series of explosions of things being squished by how big the star is.
Dara: Okay, we may come back to this.
Dara: Okay.
Dara: Point is, outside the star, there's still a big disc of dust, okay?
Dara: Big disc of dust, right?
Dara: And some of that clumps together and it sort of spins because gravity makes it spin.
Dara: And the bits of it clump together into little, like, little regions, little lumps, basically, and they come together into these little lumps and those become planets, because they are, if you think the king of it all is a star in the middle, the lumps that go around that star, they're the planets.
Laura: We're all just dust balls.
Dara: No, we're sitting on one at the moment.
Dara: If you pull enough dust together hard enough, it turns into sometimes when you.
Laura: Look under the bed and there's like, little dust balls.
Laura: That's the start of a planet.
Dara: Yeah.
Dara: Look, dust is a very strange thing.
Dara: It does a lot of definitions.
Dara: Dust is a weird thing, does covers a lot both at home and dust is a really nicely vague term for just bits of matter, essentially.
Dara: But they're all lying out in the big and they and they kind of accrete.
Dara: They clump together and the ones that the ones that go around the sun.
Laura: Hang on, where did the dust come from?
Dara: The dust came from first from the creation of the universe.
Dara: The Big Bang threw out loads of stuff and then stars clump together and they create other elements.
Dara: They start with hydrogen.
Dara: Stars make other elements.
Dara: This is the yes, that's the face.
Dara: Stars make all the elements with the covalent bonding no, with the squishing together, squishing fusion.
Dara: They squish them into other they fuse them by just squishing them together.
Dara: So hydrogen gets squished until it becomes helium.
Dara: Right.
Laura: So basically squish me.
Ron: Hang on, hang on.
Ron: See, hydrogen, yeah.
Ron: One proton in the middle, helium two.
Laura: So they get squishes.
Laura: Yeah.
Laura: This is my periodic table.
Dara: Yeah, exactly.
Laura: So the helium is sandcastle of stuff.
Laura: That's what I call it.
Dara: Yeah.
Dara: So helium is slightly bigger than hydrogen.
Dara: It's like hydrogen.
Dara: It's actually two things squished together.
Dara: But the process of squishing the hydrogen together, there's a little bit extra stuff left over and it's a kind of complicated process, obviously, but a little bit extra stuff left over, including lots of energy comes out and that causes all the heat that's happening.
Dara: But in the centre of the sun, even as we speak now, it's a big furnace that basically is squishing hydrogen to make helium.
Dara: And then it starts squishing the helium to make other things, carbon and things like that, and then squishes those.
Dara: If it can keep going, if it's big enough to keep going and going and going, it'll squish those to make heavier things, it'll squish those.
Dara: And eventually a supernova will cause a massive squishiness.
Dara: Loads of things, big things, to squish together and create all the really heavy things, bigger than iron things.
Dara: So everything is made in stars.
Laura: I really hope that there are some science books out there called, like, squishing.
Dara: And Clumping, squishing and Conflicts.
Dara: You won't be on because it's not like you're making small, you're just pushing them together.
Dara: You're basically pushing them together.
Dara: What would be an excellent example of this?
Dara: Two rolos if you want to make a super rolo.
Dara: No.
Dara: Better yet, not Maltese.
Dara: Let's go for minstrels.
Dara: They have a hard shell.
Dara: So let's presume that there are lots of complex forces that don't want things to be squished together, but you can overcome them.
Dara: You can overcome the hard shell of a Malteser by just pressing hard against another Malteser.
Dara: Or do you push it together?
Dara: It cracks that hard shell and you create super minstrel.
Dara: Minstrels.
Dara: I know a multi is super minstrel.
Dara: A Maltese would complicate things because of its honeycomb shell.
Dara: But you create a super minstrel, which is basically so hydrogen is just a minstrel and you get another hydrogen.
Dara: You push them together, you squeeze them really hard.
Dara: Or do you crack that?
Dara: You get past the bit where it has to crack and then you squish them together into being super minstrel and that's helium.
Dara: And then you got to load superminstrals.
Dara: And what you do is you push them together as well and the force is sufficient to crack them together to make other things and then the other things get squished together and so on.
Dara: So the process basically builds up more and more of the elements.
Dara: All the elements basically have to be built like that by taking mince flapping about the sun.
Laura: Sorry, they're just all flapping about in the sun.
Dara: Well, yeah, the sun is basically a big ball of suddenly, like, boop, a bit of lead appears, lead down there.
Dara: Because basically you need to have a shell, you need to have a supernova, I think, to create leads farther.
Dara: I'm going now is the point where.
Ron: You iron massive heaviest you can get.
Dara: And that force takes big, heavy elements and smashes them together.
Dara: So getting all the way up to the top of the chain is quite difficult to do.
Dara: Right, so we live in a universe which is a lot of hydrogen and a lot of helium and a lot of carbon.
Dara: The simpler ones and then the really, really big ones, gold, whatever.
Dara: That's why they're in such rare supply, because not that many stars have gone through the different generations or have been big enough to get to the point we make lots of gold.
Dara: So that's the thing.
Dara: The universe is full of diamonds, but it's not full of lots of gold.
Dara: That's a one way to look at it.
Dara: So you basically squish them all together.
Dara: Tomato and the act of squishing.
Dara: The bit where the, where the two, where the shell of the, of the minstrel cracks, right?
Dara: That bit, that bit where you go, great, I've got them together.
Dara: Right?
Dara: That bit in the actual physics is a massive release of energy and so that's why it's so hot.
Dara: And then it releases all these photons of light and they bang, bang, bang, bang, bang, bang, bang around the middle of the sun for like literally a million years until they reach the outside of the sun.
Dara: And then they come out of sun rays.
Dara: Yes.
Dara: So that action of cracking the two minstrels together, of squishing them together to make a big minstrel, like a bigger element, releases a load of light, basically.
Dara: So if you imagine yeah, two minstrels and you push and push and push, and then eventually you went over some boundary, basically, you went click and a squishion together.
Dara: Loads of light appears when you did that.
Laura: Yeah.
Laura: Okay, so we said the heat of.
Dara: The sun and also within the sun.
Dara: Then the sun is a big ball of light just bouncing off all the bit and slowly, on average, it takes a million years to get from the middle of the sun to the edge of the sun, where it just goes and shoots off into space.
Dara: Takes eight minutes to get to us and a million years to get from the middle of the sun to the edge of the sun.
Laura: Exactly.
Dara: Yeah.
Dara: But anyway, that's always happening in the middle.
Laura: That's like that feeling, you know, when you're on a train and they're like, this train will divide and then it takes like 40 minutes to divide, but you're getting off of the next stop anyway.
Laura: So you're like, just oh my God.
Dara: Yeah, just build a longer platform.
Dara: That's always the situation.
Dara: Or why can't people why can't people just climb down onto the ground and walk along and then climb back up onto the platform?
Laura: Again, only an eight minute journey.
Laura: Why is it taking me a million years to just to get to the edge of it?
Laura: Livid like being at Houston when it's.
Dara: Business, they don't say, oh, by the way, this house you're looking at, they'll say, look, it's one of your locators.
Dara: It's a 23 minutes journey into Waterloo.
Dara: They won't go, but you have to be in the first four carriages.
Dara: That warning has never applied anyway.
Dara: So that's what's happening in the middle, right in the middle of all of our solar systems.
Dara: And on every bright dot you see in the sky, most of the bright dots in the sky, you see, that's it.
Laura: You listen to this sciency stuff here because this is science now, where you say a rule and then you sort of mumble.
Dara: Some of the bright stuff you see in the sky are planets.
Dara: If you look up in the sky dust balls, you'll see yeah.
Laura: And we'll get to why cold dust balls.
Laura: We got cold dust balls and hot.
Dara: They're not cold.
Dara: Venus is really hot.
Dara: But you'll also see them from Earth.
Dara: You'll see the other planets and they'll be also doctors.
Dara: And people sometimes mistake them for study.
Laura: Is Venus actually green?
Dara: No, it's not.
Laura: This is the other problem with science, is the more you learn about it, the more all the cool stuff isn't real.
Dara: Venus is incredibly cool.
Dara: Venus?
Laura: You just said it was hot.
Dara: Venus has clouds of sulfuric acid raining constantly.
Laura: All that sounds brilliant.
Dara: When the Russians failed in game to the Moon, they shifted their focus to game to Venus instead.
Dara: And they landed a series of probes on Venus.
Dara: And the longest any of them lasted was 90 minutes.
Dara: And they kept getting through the atmosphere, and they may be hit by sulfuric acid rainstorms and just dying, and they'd send another one up, like and then they got I think the most they ever got out was, like, an hour or 90 minutes before the thing just.
Laura: Went, no, send it out with one of those golf umbrellas.
Dara: Honestly, there's no point.
Dara: Then you're just holding like that cartoon.
Dara: I'm just holding an umbrella with just the metal bit instantly does that, like whatever.
Dara: So it's really, really venice is awful.
Dara: Venus is a terrible place, the worst place.
Laura: But there is actually a ball in the middle of it.
Laura: Is there?
Dara: Yeah, there is for those there is a debate about the further ones out.
Dara: Basically, imagine we had a star and then there was a disc of stuff, basically dust.
Laura: Let's go back to dust.
Dara: Dust and gas.
Laura: But this is a disc of dust.
Dara: A disc of dust and gas.
Dara: Right.
Dara: Heavier stuff was contained in near the middle and the lighter stuff where the star got formed, pushed out the lighter stuff so it was on the outside.
Dara: So in other words, when you look at our solar system, it's rock, rock, rock, rock.
Laura: And then it's gas, scissors, paper.
Dara: No, there's no scissors or paper.
Dara: Scissors, no scissors.
Dara: Nothing beats gas, beats rock in many ways and that's that's not helping in any way.
Dara: But anyway, heavy stuff is in the middle.
Dara: So Mercury, Venus, Earth and Mars are all rock planets.
Dara: And then there's a band of asteroids, basically.
Dara: And then you get out to are they small planets?
Laura: Kind of.
Dara: Some of them are, regardless.
Dara: Dwarf planets.
Dara: Yeah, because that's the distinction we have.
Dara: Yet planets are the things that are like they're big and independent.
Dara: They do their own thing.
Dara: They go in a big circle, they clear that circle.
Dara: That's really important.
Dara: They're big enough so they end up being regular shaped.
Dara: You can see all the ones you know, that I've listed.
Dara: There are all regular shaped circles, basically, and so they're all doing that.
Dara: They're all planets.
Dara: And then moons are stuff that stuck to the planet and they just go around the planet and that's a distinction.
Dara: They're also like sometimes our moon is a sphere, but sometimes there are really uneven things like the ones that I said, mars, Phoebes and Demos are weird shaped ones.
Laura: I'm still going stuck to the moon.
Laura: Then.
Dara: We have cleared most of the dust out occasionally, so gets bombarded and rocks come in from outside commerce thing on long arcs and they just bump into them as well.
Laura: So the moon is not like working on gearing up to be in a full planet.
Dara: It will never be.
Dara: What will happen is slowly the moon.
Dara: The moon is slowly moving further out from us.
Laura: Oh, no.
Dara: Yeah, I know.
Laura: I love the moon.
Dara: The moon is cool.
Dara: The moon is great.
Dara: I mean, watch my Channel Five documentary about the moon.
Dara: But the moon is cool.
Dara: Because of the moon, we have a 24 hours day.
Dara: We used to have a four hour day when the planet was formed.
Dara: Then about the planet was formed about four and a half billion years ago.
Dara: Right.
Dara: About 200 million years after that.
Dara: This is the current theory.
Dara: Something smashed into Earth.
Dara: Right.
Dara: A big rock smashed into Earth, dislodged a load of stuff and over time clumped together to become the moon.
Laura: Oh, no.
Laura: So the moon used to be part of us.
Laura: And it must be so lonely now, just hanging around on the edge here.
Laura: Guys, do you miss me?
Dara: And it's really dead because it was volcanic for a while, but it's not volcanic anymore.
Laura: I was probably actually looking at the Earth and like, thank God I got away.
Laura: Look what the humans are doing to it.
Ron: Kind of an abused partner, though, because it kind of just sits out there taking a lot of flak for us.
Ron: It's riddled with craters.
Dara: It shielded us from a love.
Dara: It wasn't a great environment.
Dara: It took the hit of a load.
Laura: Of stuff even more now.
Dara: Also, if we're Anthropomorphizing moon, you've got to decide which side is it the side facing us is the anthropomorphic side or is it looking out?
Dara: Because we never see the other side of it because the moon is damped and it would spin like everything else spins.
Laura: It's damp.
Dara: It's damped, damped, damped.
Dara: What it means is basically the moon shifts the water around.
Dara: It pulls the water around the planet.
Laura: Yeah.
Laura: I think that's not true.
Dara: It's very much true.
Dara: Yes.
Laura: I cannot understand how that could just gravity.
Laura: Yeah.
Dara: Okay.
Dara: Imagine shattering.
Dara: Imagine still.
Dara: Imagine a still thing.
Dara: You got a planet, right?
Dara: US.
Dara: Okay.
Dara: You've got a moon.
Dara: And our moon is relatively the biggest moon in the solar system.
Laura: Yeah, it is.
Dara: But relative to us, there are bigger moons on other planets, but they're bigger planets in terms of the effect that the moon has on us, is bigger from our moon than any other moon in the solar system.
Dara: So, yeah, our moon punches above its waist.
Dara: Well done, our moon.
Dara: Buddha boss.
Dara: Congratulations.
Laura: Moon monthly.
Dara: Yeah.
Dara: We're very pro moon.
Dara: But if you imagine the moon is sitting here, right, pulling because it's gravity pulling on Earth.
Dara: Right.
Laura: Why isn't our gravity pulling hard?
Dara: It is equally pulling.
Dara: That's why it's not flown away.
Dara: So we're kind of pulling.
Laura: I'm so stupid sometimes.
Laura: Yeah.
Laura: Because the water is staying on the planet.
Laura: You're right.
Laura: I agree.
Dara: Actually, the water does get drawn to the moon on one side, right.
Dara: And on the other side really weirdly because it's the farthest part away.
Dara: It moves away from the moon.
Dara: So it's sort of like our planet in an extreme form.
Dara: If you imagine our planet is a circle and the water is like a rugby ball on top of that, it's obviously not that much.
Dara: It's not that pronounced.
Ron: This is where you got the idea that the moon was squeezing the Earth, which was a theory Laura had for some time.
Laura: There was this, it was this but Dara's explaining it better, that's all, basically.
Dara: And as it moves around, it sloshes the water around.
Laura: The stuff at the back is like, oh, you're too far away, I'm going to go away too.
Dara: I don't even need you, I'm going to fall back because you're pulling me less than you're pulling the rest of stuff.
Dara: Like so end of a two peaks, you end up a peak on either side of the planet.
Laura: I think it must be awful being the sea.
Laura: I'm not sure if always all over the place.
Dara: Everything is helping physics here.
Laura: I can't help it.
Dara: I get as a defence mechanism, personalised thing, but I just see it's too huge to anthropomorphize, it's too big and amorphous and it's like 71% of the surface.
Dara: Are you saying the Atlantic and the Pacific, are they all one character or are they a series of interconnected?
Laura: I'm worried about them now because they're just spending their whole life trailing about after this rock in the sky has.
Ron: Bigger problems than the moon.
Laura: I know the Orcas, they're up to stuff at the moment, aren't they?
Ron: Imploding billionaires everywhere.
Laura: Yeah.
Dara: I would say it's more reaching for the moon than it is trailing around.
Dara: And actually weirdly, because the moon is moving independently, it's kind of dragging behind it or no, is it hang on drag mode or is it pulling it along?
Dara: I think, anyway, one of the two.
Laura: Also, the sea is like the moon's comfort blanket.
Dara: Maybe that's a way to put it.
Dara: But anyway, it's just a sea yearning.
Dara: And because of that, it's slowing the moon down, which, ironically, makes the moon move further away because of the moon.
Laura: Yeah, you would.
Laura: You can't be in a constant relationship with someone that's dragging you down.
Laura: You have to break away.
Dara: I just don't say space at this point.
Dara: You need your own arena, you need your own area just to yourself.
Dara: So our moon is slowly moving away from us.
Dara: It's slowing our day down.
Dara: As I said, we had a four hour day before the moon came along and now we got a 24 hours day, so that's taking us, whatever, 4.5.
Laura: I bet the Daily Mail had a lot to say about that when there was only a four hour day.
Laura: These work shy layabouts copying the scandi work week with their four hour days.
Dara: Look.
Dara: And so that's what satellites, moons just kind of hover around something.
Dara: I get why it would be confusing, because we just hover in the sun, right?
Dara: We're just hovering in the sun.
Dara: And the sun is part of like a galaxy that just spins around a big black hole, a big black hole in the middle of the Milky Way, like the S.
Dara: So so we're all spinning around stuff and then that whole stuff is kind of moving, so there's a lot of movement.
Laura: We could be a moon of the sun if we decided to term it that way.
Dara: You could absolutely name it that way.
Dara: And then we have moons of arm of us.
Dara: Yeah, you could entirely say that.
Dara: And also you can then send a satellite up to be a moon of the moon.
Dara: You could have a moon of the moon, which is a moon of us and we are a moon of the sun.
Dara: They're just names for what's happening.
Dara: What's happening is fairly clear.
Dara: I think the naming of it is a bit that's kind of confusing, but yeah, the satellites got created by extra lumps of stuff and it was just it wasn't close enough, basically to get sucked into the planet.
Dara: So it's it stayed outside the just the catch of the planet falling around and around and around.
Dara: By the way, the reason we started this is because you want to know the difference between speed between scalars and vectors.
Laura: Yeah.
Dara: Do you remember that?
Dara: That was like a while ago now.
Laura: Yeah, we just forgotten that bit because that bit's pretend.
Laura: Whereas this is actual thing.
Dara: Here's why it's important.
Dara: If you just say the speed of something in space, it means nothing, right?
Dara: But if you see the speed in the direction when you're spinning around something in orbit, you're kind of always avoiding being caught by the planet.
Dara: Like when we send up a rocket, we send it and we shoot at an exact speed, like 70 and a half thousand miles per hour.
Dara: So it's always falling slightly away from the planet but never falling towards us.
Dara: So that's how we keep something in orbit.
Dara: You keep it falling, falling, falling, falling, falling, but never so slowly that it falls back down to Earth.
Dara: It's always just slightly ahead of, ahead of Earth's pull.
Dara: It's like surfing a wave that you never quite crashes and you're always kind of doing that.
Dara: Okay, so its speed doesn't change, but its direction endlessly changes.
Dara: Its direction changing all the time in a big round, round, round, round, round, round round.
Dara: And that's why it's important to be able to have, say something has both speed and direction because it's clearly changing, but just its speed is not changing.
Dara: Does that in any way help you have very much put on a sour.
Laura: And which one is that?
Laura: Is that a vector, then?
Dara: That's a vector because vectors are bigger and better and more important.
Dara: They have two.
Laura: Does north and east and west still happen in space?
Laura: Do you still have no how do.
Dara: You do directions in space?
Laura: Why are you laughing?
Ron: Where would the map.
Dara: Point.
Laura: I don't know.
Laura: How do you do directions in space?
Dara: There are very complex things for all that's.
Dara: Very complex.
Dara: We can call up an app and you can tell where every star is.
Dara: It's quite mechanic.
Dara: It's quite clockwork space in a certain sense.
Dara: I can tell you exactly what star is exactly in that direction in 1000 years.
Dara: So it all spins around.
Dara: It's amazing how it does it's like whatever and so on.
Dara: Any you can get an app on your phone and just go, right, well, it will automatically tell you very easily.
Dara: Are you pointing this way at this time?
Dara: Yeah, that'll be Ursa Major or whatever there.
Dara: So it's all quite mechanical.
Laura: Do you actually navigate by the stars then, if you're sending a rocket out?
Dara: No, you don't navigate by the stars.
Dara: No, you don't.
Dara: But when you send a rocket out, you have to constantly recalculate.
Dara: Constantly recalculate because everything is moving if you're going to the moon.
Dara: And what you're actually doing is you're actually I don't think this is going to help in any way when you go into or you don't just I mean, for example, the the spaceship, the space tingles path, the ISS, that's the one that goes that's constantly going around.
Laura: Oh my God, that's my worst nightmare.
Laura: That thing.
Dara: Even the size of it, or being up there or getting being on it.
Laura: Can you imagine?
Laura: Just like being in a f****** Holiday Inn, but with terror at every door.
Dara: With all horrible, horrible it'd be all people talking about science.
Dara: Yeah, it's most people's like bucket list.
Dara: Greatest thing they could possibly do in their life.
Dara: Anyway, that's only 250 miles above us.
Dara: It's really close, but it's moving.
Laura: Quantity.
Dara: Well, that's a scalar.
Dara: It's at the distance, it's spinning around and people are floating around.
Dara: Right.
Dara: Floating around up there.
Dara: Either they're in microgravity, it's called.
Dara: There's no gravity on them.
Dara: And that's not because there's no gravity up there, it's because they're falling.
Dara: They're in free fall all the time.
Dara: If you got a ladder, a 250 miles ladder and climbed up the 250 miles ladder and stepped off, you'd not there.
Dara: You'd fall right back down really quickly.
Dara: It's only because when a lift goes down and for a second you feel lighter.
Dara: If the lift dropped, you would float.
Dara: You'd hit the ground, obviously, because before you hit the ground and were crumbled, you and the lift would fall at the same speed.
Dara: So you'd have no weight within the lift.
Laura: Yeah.
Dara: So you would be weightless as you fell.
Dara: Okay, that's free fall.
Dara: If a parachute jumps out of a plane in a box, it might look like he's just in a room, but they're both falling at the same time.
Dara: And so you will be weightless within the box.
Dara: You're clearly both you're falling, you've been dragging down.
Dara: Would you be weightless within the box?
Dara: The internal space station is falling all the time, falling.
Dara: So that's why they feel like they're weightless, but there's tonnes of gravity up there, but they're just constantly in a lift that's dropping at full speed down to the ground, but it just misses, it keeps missing.
Dara: It's on a perfect path to just keep missing the earth.
Dara: So just volley, volley.
Dara: Volume, volume.
Dara: Falling in a big circle all the.
Laura: Time, it just sounds horrible.
Laura: Would you go?
Dara: Yeah, I'd go in a shot.
Dara: I'd go, but I'm a big.
Dara: I'm twice the size of most astronauts.
Dara: They're all five foot nothing.
Dara: They're very much like jockeys.
Dara: They're drawn from the same gene pool as jockeys.
Dara: It's either one or the other.
Dara: If you emerge that size, either that jockeys or cleaning mills in, like, Dickensian London, very small.
Dara: You could go chimney.
Dara: That's it.
Dara: That's the only thing you could do.
Dara: In many ways, their potential, their lives have improved enormously since Dickensian times.
Dara: From cleaning mills to jockeys to astronauts.
Dara: That's quite a journey that the small have had.
Laura: It's huge for us.
Laura: It's huge.
Laura: Our community is delighted and I'm very.
Dara: Proud of them and what they do, but no, it absolutely will go up.
Dara: Yeah, it'd be amazing.
Dara: But, yeah, you're just falling all the time.
Dara: All the time.
Dara: Falling, falling, falling.
Laura: What's your favourite thing in space?
Dara: Look, of the many things in space.
Laura: It can be a type of thing, like a flavour, like, oh, I love suns, or whatever.
Dara: Yeah.
Dara: No.
Dara: Do you know what I love?
Dara: Nebulae, which are big clouds of gas after thing goes supernova.
Dara: Some stars, depending on the size of a star, sometimes they explode, go supernova, and they expel all everything that's in the star, all the stuff they've made, all the heavy things they've made, and they explode them out into a big cloud, right?
Dara: And those clouds become nebulous, which become then the place where more stars are built, because clumping happens and they and they create stars.
Dara: So there's big massive clouds of dust in space from which stars are created.
Dara: They're very beautiful.
Dara: Some of them are ones that some of the ones called Plantery Nebulae, which are just like a ring of you see, you've heard things like the Crab Nebula and things like that.
Dara: Those things mentioned, Orion's Nebula, they're these brightly lit sort of clouds in space.
Laura: Which Green savers that's my favourite.
Dara: They are the most standard bar fish.
Dara: Your bog standard.
Laura: Is that light refracting off them, then?
Laura: Is that why they get so colourful and beautiful?
Dara: No, what happens is they are colourized and there is energy coming off them, but it's because they are heated.
Dara: They're slightly heated within a very dark universe, so they're emitting energy, some of them.
Dara: If you type in Dumbbell Nebula, have you got a thing there that you're looking at?
Dara: Dumbell Nebula.
Dara: What that is, is literally, you know, the way it's in the circular shape?
Dara: That is the cloud of stuff expelled from an exploding star.
Dara: So at the heart of it.
Dara: There's a core to that, and that is the outer shell of stuff.
Dara: And it was in a massive explosion millions of years ago, but it's still slightly hot from that and it's sending out bits of light and bits of light in different colours.
Dara: So you can actually see that's what you actually stick a camera down and that's what you'll see.
Dara: So that's the ground core.
Dara: There are other ones which are big clouds that are the Orion Nebula, for example.
Dara: That's just a big cloud of stuff, but it has absorbed and is emitting light showing, so it picks up light and it sends out energy.
Dara: That means that we can see it.
Dara: So those things are cool and there's.
Ron: Loads of them in space and those will eventually reclump.
Dara: Right.
Dara: Within those areas, stars will be created.
Dara: Yeah.
Dara: I mean, they cover a vast amount of space and stars will be created within those because the clumping will happen again.
Laura: So does a solar system always starts with the star, the solar and then.
Dara: Everything else is kind of the extra bit success over after.
Dara: Yeah, absolutely.
Dara: And there could be more than one star in a system.
Dara: Sometimes two stars create that and they're close to each other, so they end up going around here, like in Star Wars.
Dara: There's a planet that Luke looks out and sees two stars in tattoos actually fighting, but that just no, they end up in a kind of a complex dance around each other and there are planets to circle one or the other.
Dara: And then on that planet, you would see two stars and you might have might have no night or you might have bits where they're both on the other side, but you would see two stars in your sky.
Dara: There are triple ones as well.
Laura: I just can't imagine understanding this planet well enough to worry about learning about all this as well.
Dara: That's already to look around.
Dara: But if you look up, there's an amazing amount of information that's come to us and because of what we've learned from up there, we know better how this works down here.
Laura: That's a good point.
Dara: And actually, the thing is, at some point in our history, in a long way, we will be long gone.
Dara: You won't see anything because the universe is expanding and eventually stuff will be too far apart and we won't be able to see, no light will come to us and we won't be able to learn anything about life on any other sphere, will be long gone.
Dara: It'll be really cold.
Laura: I don't want to survive.
Dara: It's not how it all ends.
Dara: It all just tins out.
Dara: All just tins out and everything just stops, runs out of energy.
Dara: So you don't do, for example, the Big Bang.
Dara: You don't do that.
Laura: Sorry, say that again.
Laura: I was really depressed for a second.
Dara: I'm sorry.
Dara: The heat test of the universe is quite depressing, but you don't have to do the big bang then, at all.
Ron: No, combined one.
Dara: Honestly, you're missing some of the better physics because at least it's some poetry to space a lot of physics.
Dara: And I will say this is actually.
Laura: More like chemistry, though I think so far this has mainly been chemistry.
Dara: Well, no, because a lot of us do a gravity, and the force that brings all these things together is gravity, and that's not the thing that really work on a small level.
Dara: So you're talking big scales and how it all works.
Dara: Chemties is a different thing entirely because this kind of stuff is the poetry.
Dara: There's a lot of stuff that you're doing about springs, I'd imagine, and light passing through one medium and the next medium, and that sort of feels a bit like low stakes, I would say.
Dara: Yeah, it feels like there's not a lot of very interesting things happening there.
Dara: And it does feel kind of like no, you're not allowed play with the real yoyo until you just learned how to hold the string in your finger and you have to learn how to do the whole thing.
Dara: It feels like a lot of that, like, yes, you can ride a bicycle once you've done these seven trainer wheel bicycle.
Dara: When you've learned how to when you show me that you can do stepping on a pedal right, or something, roll a ball down.
Dara: This course is really not the thing.
Dara: And the reason people get into this is because you read outside the course is because you read a book at 14 that tells you what the shape of the universe is or and you go, oh, my God, and your brain go, and that happened.
Dara: And then because this is not going to turn you into wanting to be a physicist at all, because if I put more weight on the spring, if I put twice as much weight in the spring, the spring will go twice as far.
Dara: How exciting.
Dara: It doesn't seem like I'm really doing anything amazing here, but it is unfortunately just a training.
Dara: It's weirdly.
Dara: Like this subject exists to train the tiny percentage of people who will carry on all the way, who you can't pick out now who they are, but when they get to the point where you find out who they are, it's really important that back then you taught.
Laura: Them all this stuff, right?
Dara: Yeah.
Laura: Why did you get into it then?
Dara: Were you I had a teacher who went off peace at a point in the Irish education system where there was a gap where we didn't before we said did the syllabus.
Dara: And he said, well, why don't I just teach you?
Dara: And he taught us loads of stuff, actually.
Dara: He did, in the sex education classes, which are exciting in a Christian Brother school because they had master walked in and he'd drawn a p**** on the board accurately or fallopian tubes or something, and he stood in front of it when the headmaster came in, said, oh, hello, yes, we're doing very well, blah, blah, blah.
Dara: And we were all like because we were really on board with the fact that, oh, God, somebody's actually going to teach you this stuff.
Dara: And then the headmaster went out and he stood back on.
Dara: That was the level to which we all felt this is a secret meeting that we're having in which somebody will finally explain to us what sex is.
Dara: But then, as well as that, and I think those lessons are very important, but as well as that, he then went, oh, look, black holes.
Dara: And they do this, and there are these massive destructive things where star collapses in and all space gets bent around it.
Dara: And if you followed it, you can't come out and you're like, wow, what's that?
Dara: Until I read more.
Dara: About 14 is a magical age for this.
Dara: The stuff just kind of gets in your head.
Laura: So where are you?
Laura: If you're in a black hole, you're gone.
Dara: If you're in a black hole, you're.
Laura: A tiny dot because all your matter has been squashed.
Dara: Squish.
Dara: Squished.
Dara: I mean, as we said, we're talking about squishing.
Dara: It's an extreme star.
Dara: It's a really huge star that did all this stuff and yet there's loads of it over and eventually the burning of the stuff keeps the star from collapsing, essentially because when you're scratching all the stuff and also we smell that pushes the other bits out, but it's eventually you run out of things to burn and they just keep coming in.
Dara: And sometimes you create a thing called a neutron star, which is incredibly dense star at the end of its life, it just becomes like I think that if you hold a spoon of it would weigh the same as New York City.
Dara: I think that's a general comparison drawn.
Dara: It's incredibly dense, but sometimes just loads of neutrons or stuff and to just squeeze in really, really tight.
Dara: I don't think it's just neutrons in.
Laura: The thing, but yeah, anyway, neutrons are the mixing desks.
Ron: Sound engineers.
Laura: Yeah, sound engineers.
Dara: Okay.
Dara: I feel that's not a thing that.
Laura: I know why you atoms are made up of the neutrons of the sound engineers.
Laura: And then the electrons are coming to a party, and depending on how loud they can hear the music is whether they're going to stay at the party or go somewhere else.
Dara: Okay.
Dara: And the protons, they are because the.
Ron: Electrons are negative, so they're sad in Laura's world, sad boys.
Ron: The protons are Bob Marley giving out positive vibes, and that keeps the negative.
Laura: Play in the music.
Ron: But then the neutrons, they're neutral.
Ron: They're just sound engineers.
Dara: They're just yeah, okay.
Dara: Yes.
Dara: Within the situation, presumably, the protons are single people that electrons want to hook up with.
Dara: That's important.
Laura: The electrons hook up with each other.
Laura: Electrons only they're little emo couples.
Laura: They sit next to each other on the bus.
Dara: The electrons don't hook up with each other because they're on the same charge.
Dara: They repel each other.
Laura: Yeah.
Laura: But sometimes they like to go in pairs.
Ron: Yeah.
Ron: They pair up in the valency shells.
Laura: Yeah.
Dara: Yes.
Dara: But they're really pairing up with the protons.
Laura: Oh, no.
Laura: This is the only thing I've understood in a year now.
Laura: It's being undone.
Laura: This is science's problem.
Laura: He tells you a thing and then goes, but it's not actually that at all what happens.
Dara: The situation is that you've got two atoms and they share two electrons.
Laura: Yeah.
Dara: The electrons themselves don't come together, but both of the things around them share those two electrons.
Dara: They both claim them as their own.
Dara: It's like there's two parties next door to each other and the two electrons.
Laura: Are smoking in the front garden and listening to the music of both parties.
Dara: If you imagine, there's two parties and they open up to the one hallway and these two electrons are both in the hallway.
Dara: So the people organising the party, because it's really important for the people organise the party that they have as many electrons here as there are protons, so that maybe in some sense, they can all get together, because the protons have hosted a party to meet electrons.
Dara: So that's what they really want to do.
Dara: And they're really sad, the protons, even though I know that if there are fewer electrons than there are protons, it makes them really unhappy.
Dara: So they seek out a situation where you can have the same number of electrons.
Dara: That's how they bond.
Dara: So they want there to be a balance in pluses and minuses.
Dara: So the protons want the right number of electrons to come along, but sometimes they both are missing one.
Dara: But ones on the outside are standing at the doorway and they're in the hall and both parties go, well, the hall is part of our party too, so they can both claim the other one's electron.
Dara: So those two electrons aren't linked together.
Dara: They just happen to be standing in an area that the two parties can both claim, make them.
Laura: That's the electron.
Laura: I'd want to be just a bit too cool to be on the dance.
Dara: And you've not committed.
Dara: There's your actual friends who you like, but then there's also these really cool people that you occasionally hang out with, like, whatever, but you don't dump your actual friends, but you also want to keep in with these new guys you met because first year in college and whatever, you might end up eventually dumping your actual friends and hanging out with new shinier friends, but for the time being, you don't be accused by your original friend, the UKM, with as being, oh, you're such a user.
Dara: You brought us here.
Dara: So that was totally me.
Dara: Those electrons are keeping their options open.
Laura: Yeah.
Laura: They're more exhausted than the sea.
Laura: There's so much going on for everything.
Dara: Isn'T there there is a lot going on.
Dara: So that's what they're doing.
Dara: Okay, I now get it.
Dara: And the neutrons, you're absolutely right, are just running the coffee, are running the tuck shop at the at the disco.
Dara: They're not influenced by anyone.
Dara: They're the parents who come to collect people, or they're the teachers.
Dara: Who are the teachers?
Dara: They're the teachers and the teachers.
Dara: Okay, you've chosen a thing.
Dara: Why am I ruining it?
Dara: But they do nothing.
Dara: Anyway, the point is, neutrons are in the neutron star.
Dara: If it's a really big star, it's so big that even squishing down the neutrons, that side isn't enough.
Dara: It just goes and it falls behind a certain limit and it falls down to a point, and that's a black hole.
Dara: And it becomes this area in space becomes a point of almost infinite of infinite density of this.
Dara: And everything that gets near it will get sucked into it and gets squished into this thing as well because the gravitational pole is so huge.
Laura: What happens?
Dara: Everything just things fall into it all the time.
Dara: Things fall into it.
Dara: Stars fall into it.
Laura: They go no, how do.
Dara: All the time.
Dara: And you see it because the stars are coming, like, say, sideways on us.
Dara: And if you imagine if you imagine.
Laura: Just crab walking into a black hole.
Dara: Yeah, if you imagine sorry, why does it say that you want the waitress?
Dara: The waitress is walking past your table, but you go and you pull the waitress, but she's getting a tray of stuff.
Dara: The tray of stuff often gets fired off as you pull the waitress towards you.
Dara: This is kind of sounds sleazy the tray out.
Dara: And we see the tray and we go, oh, hang on.
Dara: What's happened here?
Dara: Why is there a tray being flung?
Dara: Why is this loads of other stuff being sent off?
Dara: Because it's being torn off the planets as it falls into the black hole, and this stuff is sheared off, and there's a massive amount of radiation released when it happens.
Dara: So you can see the effect of it happening in various ways, but they're astonishingly cool, but they're the most destructive thing in the universe.
Dara: You fall into it, you are gone.
Dara: You get to the point, you get over the event horizon, nothing is happening.
Dara: Nothing is happening.
Dara: You're not getting any message out.
Dara: You're not getting a light out.
Laura: But are you still alive in there?
Dara: No, you're not.
Laura: You're really not.
Dara: No, you're not.
Laura: No.
Laura: I don't know which is worse now.
Laura: Eventual heat death or black holes would be quicker.
Dara: You got to save the black hole because you're spaghettified, because the difference in gravity is so extreme that it pulls you, extends you really sharply, and you.
Ron: Just get hawking radiation, I believe, is a thing with black holes.
Dara: Yes.
Laura: Hawking radiation.
Ron: Yeah.
Laura: Like Stephen Hawking.
Dara: Okay.
Ron: I think so.
Laura: The second best science interview you've done.
Dara: Hawking radiation by Hawking.
Dara: And I once interviewed Stephen Hawking in his office and he had the formula for it upwritten in chalk on the board.
Dara: And you're kind of going, there's no reason for you to write that.
Dara: There's no reason that's clearly there.
Dara: So that over our shoulder.
Dara: The former for Hawking radiation is there.
Dara: And what Hawking radiation is basically the black hole seems to be sitting there doing nothing.
Dara: But every so often, particles appear and disappear in space because of quantum stuff.
Dara: They just appear for a while and they usually particle and an antiparticle appear and they kind of appear and they disappear together.
Dara: They kind of appear and then they wipe each other out.
Dara: And that happens all the time because quantum antimatter yet yeah.
Dara: And matter and antimatter appear.
Dara: But if it happens to be near a black hole, one of them goes into the black hole and the other shoots off.
Dara: And so it all balances out.
Dara: But it does mean that a black hole is slowly emitting energy.
Dara: And the energy it emits means that it slowly gets smaller and smaller.
Dara: So even the black hole, long term, eventually gets smaller.
Dara: It emits loads of Hawking radiation, which is really, quite, really difficult to pick up.
Dara: It's incredibly difficult to sense.
Dara: Hawking radiation is really, really faint.
Dara: But the black hole gets smaller and smaller and smaller and smaller and then it goes so there even it suffers from heat death.
Laura: There's just nothing happy about space, is there?
Dara: There's amazing things about space.
Dara: It's just enjoy them.
Dara: Now, long term.
Dara: Long term.
Dara: Long term.
Laura: I knew I should have had dinner before we did this because now I just feel really sad for everything that we all just like, dinner.
Dara: Are you just going to push the food on the plate going, none of this matters?
Laura: What's the point?
Laura: Eventual heat death.
Dara: What was it, broccoli or flinging broccoli against we're all going to die.
Laura: Well, I'd fling broccoli whether I was depressed about space or not.
Laura: Disgusting.
Dara: But f*** a pie gets but hang on, that was good to wear.
Dara: Oh, yeah.
Dara: Black holes.
Dara: Black holes are great.
Dara: Black holes.
Dara: They are amazing.
Dara: They're amazing, yeah.
Dara: And caging a black hole bump into another black hole and it will send it a wave of gravity, which can only be measured by setting up an L shaped like two tubes, like 90 degrees away from each other.
Dara: Imagine an L shape and you've got a laser and a laser on each of those, and they're pinging lasers off each other.
Dara: And then you'll notice that they'll go out of sync because the whole shape of space will go will go change because the gravity wave from the exposure is so huge.
Dara: And you'll be able to measure how the shape of space changed.
Dara: You enjoying that.
Laura: What is space?
Laura: Because, like, our air is air.
Laura: No, space.
Laura: What space?
Dara: Air.
Dara: Because the air is within what I.
Ron: Thought you meant like on a sort of like almost like a philosophical level of, like, what is space in relationship?
Ron: But no, you mean what is up?
Dara: It's a great question, because it's expanding.
Dara: I mean, space is expanding.
Laura: No, what?
Dara: Yes, space.
Laura: What is it?
Ron: She's asking, like, are you in some kind of soup when you're up there?
Laura: Yeah.
Laura: Is there?
Dara: No, you're not in it's nothing.
Dara: It's nothing.
Dara: It's genuinely nothing.
Dara: But the nothing is expanding.
Laura: That can't be, because it isn't anything.
Laura: The more nothing's getting in.
Dara: No, nothing.
Dara: No, just the nothing itself just is expanding.
Laura: But if it's nothing, how does it get bigger?
Dara: It just does.
Dara: Space gets bigger, for another, it expands.
Dara: And, for example, what will happen is you won't like it's not like everything magnifies.
Dara: Everything moves further apart, so you'll just move slowly apart, but everything will just move.
Dara: The tingles will stay the same size, but space will just move them apart.
Dara: This gets really kind of weird at this point, and you don't get to the limits of the observer.
Dara: That old stuff like that.
Laura: But then things have atmospheres because of gravity holding elements within planets.
Laura: Yeah, crikey.
Dara: That all carry on.
Dara: That's all fine.
Dara: That's great.
Dara: You just enjoy that.
Dara: We basically swim in a sea of we swim in a sea of gases.
Dara: That's what we're doing here.
Laura: Yeah.
Dara: When you tour a paper aeroplane, it's just basically skimming along an ocean of gas molecules.
Dara: It's bouncing along.
Laura: But those aren't in space.
Dara: Everything's in space, but they're not out there.
Dara: Yeah.
Dara: Obviously what we think of space as being a boundary is a bit beyond.
Laura: I can't think about us as being in space because then I feel sick.
Laura: I do not like the idea that planet Earth is in space is a thing outside of yeah, that'll be absolutely fine.
Dara: It would certainly be fine for the combined subject.
Dara: Space is a place you go beyond the cloud.
Laura: The thought that I'm in space, I don't want to be in space.
Ron: We're travelling at 30 kilometres a second right now.
Laura: No.
Dara: Yeah.
Dara: You just don't feel it because you're not accelerating, you're just travelling there's constant.
Laura: Which direction?
Ron: Around the sun.
Dara: Around the sun.
Laura: So we're doing the falling thing always just in front of the falling wave, essentially.
Dara: Yeah.
Dara: So you don't feel the fall.
Dara: Except that we obviously were sitting on the thing.
Dara: So we feel the gravity of Earth.
Dara: We don't feel the gravity of the sun, so we're certainly falling.
Dara: Yeah, we are, but yeah, because we're in our own localised thing that we so we we feel plenty of gravity, but yeah, we don't feel you're right.
Dara: We don't feel that way to the sun.
Dara: The windows in the morning, but the.
Laura: Planet does, otherwise we wouldn't circle.
Dara: Yeah.
Dara: So the planet we all do, but.
Laura: We just don't we're more moon people.
Laura: We're moon people.
Dara: We are, in many ways, we're moon people.
Dara: But being a moon, imagine then a moon pit and goes onto a moon.
Dara: How bad would that be?
Laura: Which planet has the longest year?
Dara: Then you go all the way out to Uranus.
Dara: Uranus will be the longest year.
Dara: Or Pluto, if you want to include.
Ron: For the whole thing, I believe it's Neptune at 60,000 days.
Laura: Wow.
Dara: Sorry, I want to say courses.
Dara: Yeah.
Dara: Uranus is the 7th and Neptune is the last.
Dara: Sorry.
Dara: Starts with the sun, ends with the sun.
Ron: Uranus, 30,000 days, Saturn 10,000.
Dara: Yeah, as you go further out.
Laura: That makes sense.
Laura: Yeah, that little rhyme is all screwed up now without Pluto, you know that my very energetic maiden aunt just swam under North Pierce.
Dara: Start with the sun, end with the sun.
Dara: That's the way I always remember, because you can kind of make up the ones, the five in the middle, sun's in the middle, and then sun at the end.
Dara: Saturn, Uranus, Neptune, and then you can probably walk around the Jupiter Saturn, and then you just have to remember, obviously, Mercury is the one nearest, and then you just we're the third rock from the sun.
Laura: We've got very different brains.
Laura: You're saying just remember it.
Laura: I just remember it.
Dara: Well, mercury fast.
Dara: Mercury fastes, we're the third rock and so on because of the sitcom.
Dara: And then you so then you just got to remember Venus and Mars.
Dara: The one that I find all different, like I just did there is remembering as a new Neptune.
Dara: Uranus starts us on the ends with Su N.
Dara: Yeah, that's how I always remember it.
Laura: Nice.
Laura: Ron, have you got any more year stuff that we need to cover before we say goodbye to the regular listeners?
Ron: I mean, I've got some year stuff.
Dara: I think we say goodbye to the regulars, probably in because I am aware of there is being two Daras and people going, oh, great, maybe it'll be fun dara.
Dara: Oh, no, it's not fondara, it's the other Dara.
Dara: It's the other Dara who insists on knowing a bit about this and going on about it as if you genuinely know the last.
Laura: I think that's what our listeners are here for.
Laura: I'm always very surprised because we call it a comedy science podcast, with the emphasis very much on the comedy more than the science.
Laura: And I do try, like, if I like a subject, we will learn it, but I don't have the functioning concentration for the stupid bits.
Laura: But I'm always amazed how many of our listeners work in science and use this as light relief to remind themselves why they like their subject.
Dara: Yeah, we've got doctors listening to this.
Ron: It's worrying.
Laura: Yeah.
Laura: There's people that listen to it while they're working in the lab and you just think, does it not just give you a nosebleed listening to us arguing about pieella and how it affects a vector?
Dara: No, because from talking about they're thrilled to be I think we're all really enthusiastic about them.
Dara: We'd like to talk shy about it.
Dara: They're.
Dara: Probably more like to be bored by me badly explaining things than they are with you.
Dara: Funnily not getting them because I'm supposed to know a bit about it.
Dara: Although what will happen is, obviously that somebody's going to come to you after, oh, I heard you on the thing.
Dara: Did you make Brian C*** tell you all that?
Dara: Which, yeah, you get a lot.
Laura: I think the big problem will be, like, why are you advocating for Minstrel?
Laura: Shows will be the big takeaway.
Dara: If they rename the suite, that will be Lee Anderson MP, and very soon.
Dara: It's been a perfectly good name for that week for generations.
Dara: There's no reason for us to get.
Laura: Rid of it, but we are going to say goodbye to regular listeners now.
Laura: So if you are not a patron, this is where we say goodbye to you.
Laura: Thank you so much for listening.
Laura: If you'd like to become a patron, go to Patreon.com Lexeducation to support the podcast and to see this final part of the interview and to see the video version of this interview, all the.
Ron: Other great content, oh, and all the.
Laura: Other lovely stuff we do.
Laura: You've got Agony dad, you've got Detentron, you've got Pop Quiz Clown, Class Clown, where we discuss laughter theory, a thing I actually know and care about.
Laura: Also, we will be at the London Podcast Festival this year.
Laura: Please go and get tickets for that.
Laura: Come and see us live in September.
Laura: But, hey, thanks for listening.
Ron: Class dismissed.
Laura: Every time, for a full year.
