FACTORALY - E76 HOLES

Episode Date: February 20, 2025

Holes are a part of our lives. Our bodies are full of them, as is the universe around us. This episode explores some of the lesser-known aspects of holes.

hello bruce hi simon how are you today i'm feeling absolutely fantastic how are you good well i'm not feeling as good as that, but I'm all right. Well, that's good. And hello to everyone listening to us. We hope you are all equally well. Yeah, whatever. I'm just more interested in talking to Simon. I mean, by all means, listen. Yes, but don't interrupt. Oh, no, please don't interrupt. So what would the people listening be interrupting?

Were they so able to do? What is this? I have no idea. It's completely blank. Okay, fine. Good. Okay, well, we'll just sit here and chinwag about whatever for half an hour. What could we say? What could we say?

Could talk about potatoes. No, done that. Potatoes? Could talk about... Vikings. Camels. No've done that. Potatoes? Talk about... Vikings? Camels? No, done that. So today we're going to be talking about those things that don't exist. Smurfs.

No. No. Well, they're there, but they're only there because of the stuff around them. Ah, they're there because they represent a lack of stuff. Yes. Sounds like a hole to me. Sounds like a whole lot of holes. It does, doesn't it?

So today, here on Factorily, we are going to be talking about holes. And because it's Factorily, we're going to be discussing it for about half an hour. And we think it's fairly inconsequential, but we're going to try and make it fun. Yes, there we go. That sums it up nicely. So holes, where on earth do you start with this? Nobody invented the hole. There's no origin of holes.

It's just a lack of the presence of something. I think you have to start with a star don't you you probably do yeah a collapsing star yes specifically if you're talking about black ones well you know going back to origin i would see as far back as that yeah so i mean that's that's as far back as i can go is the the basically the the explosion that formed the universe yes i mean that's not Egyptian or Roman or anything. No, that's way earlier than that. And did that happen within a hole?

Well, this is a good question. Did the hole come first? Whether it was actually all sucked in from another hole somewhere else and exploded out here. Yes. Well, crikey. Who knows? Okay, so we're starting as we mean to go on. Oh, yes.

Tackling the small subjects first. So what's a black hole? It's a hole. Yes. Right? That's really dark. Why is it dark? Because the gravitational pull around a black hole is so great that nothing can escape it, including light.

Wow. So all the light gets sucked into it. Allegedly, time gets sucked into it as well, according to Albert Einstein's theory of relativity. And Star Trek. And Star Trek, of course, much more reliable. Black holes are sort of an imploded star, which has then so much mass that everything gets sucked into it,

including light and space and time and everything yes um i don't you know clearly we can't go and find one and fly a ship into it and report back what happens because a they're a really long way away yeah and b if the theories are correct it would kill everyone on board well then they're not all massive though are they no i suppose not there are ones called primordial black holes okay which are absolutely tiny i mean they might be the size of an atom oh really yeah and they can't they kind of have evaporated over time but there may be loads of them all over the universe that we have no idea about right i remember there being um a bit of concern when they first switched on the hadron

collider at cern yes Yes. That if things followed their natural logical path, it might actually end up accidentally causing a black hole and we'd all be sucked into it. Yes. Thankfully, as far as we know, that didn't happen. Or maybe it did, and we've just all ended up being in a parallel universe where nothing is how it used to be yeah i mean some of these black holes are pretty big though i mean a little one is about five to ten times bigger than our sun really that's quite large yeah isn't it and and then sort of like the next level up from that is sort of like about a hundred times uh bigger than the sun right and then you get intermediate ones and intermediate ones are about sort of hundreds of thousands of suns right can you imagine something a hundred

thousand times bigger than our sun not at all no or heavier at least no so if if our galaxy ever drifted anywhere near one it's safe to say stuff would happen well there's one at the middle of our galaxy is there there's there's so at the middle of our galaxy. Is there? So at the middle of the Milky Way, there's what's called a supermassive black hole known as SGR A star with a mass of over 4 million suns. Good grief. And that's why the Milky Way spins around it. The Milky Way is in a constant state of fall into the black hole, but not quite getting there. Gotcha. Okay. Which is why you sort of look at a picture of the Milky Way and it sort of looks like an eye. Yes, like a spiral. Gotcha. Right. So we are then, generally speaking, gradually bit by bit,

all being pulled into a black hole. Yes. But I think, you know, it's not Tuesday. Fine. No. I think we've got enough time. We'll be all right for a bit. So from black holes to another colour of hole. Okay. I didn't know this was a thing until now. Blue holes. Blue holes?

Blue holes. Okay. So blue holes are anomalies that exist out at sea. Right. It's basically a sinkhole. It's a massive, great big pothole in the ocean bed where the water in the middle of the hole is deeper and therefore it looks much darker. And the water around that area, sort of sitting up on the shelf around the hole, if you will, that's the regular ocean water that's got sort of good flow and currents and so on. And that looks lighter because you can see the sand or the rock beneath. So, yes, so the currents flow around the hole but not in the hole.

And therefore, the water in the hole is still and doesn't really sort of nurture life terribly well. So, there are these strange anomalies that divers love going and exploring and sort of seeing what caused them and how long they've been there and how deep they go and all that sort of stuff. The largest blue hole is located about 100 kilometres off the coast of Belize and it's called the Great Blue Hole.

The Great Blue Hole. Imaginative. And this thing is 300 meters wide okay and 125 meters deep um and you look at an aerial photo of it and there's there's no mistaking it you know people sort of go go out on their boats or they go out diving or swimming or whatever you look down from above and it's like look look out, there's a great big hole. Oh, wow. Okay. It's quite a bizarre looking thing. Apparently, Jacques Cousteau went exploring this particular blue hole on Calypso in 1971. Okay. And they went diving down into this hole.

And where the rocks on the walls on the side of the hole have eroded over the years little branches and caverns and caves form underneath the water and Jacques Cousteau went diving down here and discovered that there were stalactites on the roof of these branches going out from the hole thus implying that at one point it was above ground so as the the hole has been formed, there have been caves and caverns and tunnels. Then the seas have risen, the hole has been filled in over time, and now it is what it is. Oh, cool.

I'll put a link up on the website if you go and have a look at our show notes on factorely.com. Factorely.com. That's the one. You'll find a 3D map of this particular blue hole. And it's a wonderful looking thing.

Do you need glasses for it? No, you're okay. It's just the magic of modern technology. It's fine. Right, okay. Wonderful. But yes, a couple of submarines went down there in 2018 and managed to get a really good looking 3D map of the thing.

And yeah, there's a whole website dedicated to this whole website a whole website funny um so yeah blue holes well talk about sinkholes yes um do you know about cenotes in uh in mexico i do not tell me so cenote is a it's a natural pit it's sinkhole. Basically, what happens with these sinkholes is that they erode either by dissolution. So it could be the water gets into some sort of sandstone and then dissolves the sandstone away and makes like a natural cave or a natural hole. Yeah. But in Mexico, on the Yucatan Peninsula, there's like a secret waterway underneath the ground. And in places, because they make an underwater river, but sometimes the ceiling of the underwater river, i.e. our ground, gives way to make a hole. Oh, I see what you mean. Okay.

So these cenotes, you can actually go swimming in them. Oh, can you? Yeah. So there's some quite famous ones where you can actually walk down and then you can go into the sinkhole, into the cenote, and then that cenote leads to another cenote. So if you want to, you can swim from one to the next one. Right. Sometimes it's underwater for a little bit,

so you have to hold your breath for a bit. Sure. Talk about stalactites. I mean, they are brilliant for that and the last time i was in mexico i had a really good time just exploring a few of these sonates wonderful how interesting i hear sinkhole and i just think of um do you remember it must have been about 10 years ago we just suddenly started having quite a lot of sinkholes appearing on british roads you sort of had the mid-morning traffic just driving

along and all of a sudden the tarmac gives out into a sort of a 10 20 30 foot hole yes um and this seemed to be quite a thing a little while back and now it seems to have stopped i don't know if that maybe we're just having a very odd year i don't remember might have been very wet i mean that for example there were i think four garages in Ripon in North Yorkshire. Yeah, that's right. They just sunk into the ground, didn't they? Yeah, they just vanished. That's right. And that was because the water had actually sort of washed away the ground underneath the garages.

Yes. Yes, as opposed to holes in the road. Yes, potholes. Potholes. Yes. So potholes are quite interesting as well. They're caused by erosion too, but they're caused by erosion from the surface.

Yes, from above and from below. And we have a lot of potholes. We do, don't we? We do. They reckon that there's a new one appears every 10 and a half seconds. Good grief. In the UK.

Really? Yes. I hadn't really realised how bad the problem was, but a friend of mine from LA lives here now. And they just sort of looked at me as if to say, why on earth have you got so many potholes in your roads? We don't have these back home. And I felt slightly offended that, you know, the good old British road system wasn't as good as theirs. But it's all because of weather, isn't it? Generally, yes.

It's freezing and thawing as well. Yes. So we get a lot of rain that seeps into the ground. It gets really cold, turns into ice. The ice expands, makes cracks. Then the ice melts. And the space that it had previously filled became space. And therefore, the ground sinks down yes but um

now from memory there was a guy who decided that he was going to get all the um potholes in his area sorted out by making them into a drawing which we shall call the cock and balls okay fine so basically he drew this around all of these potholes which meant that the council had to do something oh that's fantastic there was a welsh chap who went swimming in a pothole good grief how big was the pothole quite big that's ridiculous well i say swimming he basically was able to like jump into it up to his neck gosh i mean that's hardly even a pothole is it that's just a yeah that's just a hole well again you know that we we have the blog um i will put video of this chap jumping into a pothole

in his in his swimmers how wonderful now i wonder if that's connected to this. I found that this was a report quite recently, actually, just in the last month. There's a village near Wrexham, which I can't pronounce because it's Welsh, but there is a village near Wrexham, which has so many potholes on the main road going through its village. And they've all petitioned the council again and again to do something about it. And they've just said, nope, sorry, it it'll cost too much it's not worth our time um and they've decided to make a local tourist attraction of this road dubbing it pothole land so they've made this this little theme park as they call it um called pothole land and there are pictures and there are signs and there's a sign as you enter the village

that says, two kilometres of award-winning potholes with very little actual road to spoil your fun. This is guaranteed to be the deepest, longest and widest potholes in all of Wales. Oh dear. Yeah, I mean, potholes attract a lot of attention, don't they? Yes, they do. Well, they're quite a nuisance, aren't they? They're not just a nuisance. But,

you know, if your car is constantly bouncing in and out of holes, it can damage your car. Apparently, the AA, this is sort of a continuation on from pothole land uh the aa revealed that um the cost of repairing vehicles in this country damaged by potholes in 2024 reached 579 million pounds wow of pothole related damage that was over 1 million pounds more than the previous pothole related damage so is that damage to the road and to cars no no just to cars just a car so that was a report from the ia so that figure was just how much money people have to spend on repairing their cars because they've gone over potholes and it's damaged their their suspension or their tires yeah um but apparently the uh the cost to filling every single pothole in the UK would be around £16.3 billion.

Goodness. Hence, no one's doing anything about it. Well, no one except Rod Stewart. Go on. What did Rod Stewart do about it? Well, Rod Stewart, he got his dander up, basically. There were some potholes around where he lived. Right. And he decided just to get a shovel and some tarmac.

Yes. And basically fill in his own potholes. Did he? Yeah, because his Ferrari kept on going down potholes. Oh, I hate it when my Ferrari goes down a pothole. I know, he wasn't happy. So he basically just filled in all the potholes around where he lived. Well done, Rod Stewart. another group of celebrities who um made mention of some potholes gosh this is a loose link um

the beatles uh the beatles yes so there's there's a song lyric that has bugged me since i was a kid and i finally at the ripe old age of 46 got got round to actually looking up to what it's about. The Beatles' song, A Day in the Life, one of the lyrics said, I read the news today, oh boy, 4,000 holes in Blackburn, Lancashire. Yes. Though the holes were rather small, they had to count them all. Now they know how many holes it takes to fill the Albert Hall. And this was actually in reference to the fact that there was a particular uh road in blackburn

lancashire that had 4 000 potholes in it okay so totally in keeping with the current theme isn't it a lot yeah um and it was all in the the daily mail this was in 1967 and um the beatles just decided to you know put that in as a throwaway comment into their song. And the bit about the Albert Hall was nothing to do with it at all. It was just a nice little rhyming couplet to go with it. But apparently the Royal Albert Hall took offence at the idea of being mentioned in this song, as if to say the Albert Hall should be filled with all of these holes or something to that effect. And they officially asked the beatles to rewrite that line in the song to remove them from it and the beatles refused so there it still is to

today so how many holes does it take to fill the apple hole well that's the annoying thing it doesn't actually say no but you can work it out well i suppose it would depend on how big the holes were well they said so the beatles said although the holes were rather small, they had to count them all. Okay. So if you take rather small holes, so the average is, let's say, about 50 litres. So say a quarter of a bathtub. Okay, fine. That's a good visualisation.

So if you take a quarter of a bathtub as being the size of the hole, and then you look at the volume of the Royal Albert Hall, which is about 100,000 cubic metres, that means it would take about 2 million holes. Holes to fill the Albert Hall? To fill the Albert Hall. Would it really? If it was only 4,000,

then each hole would have to be about 140 bathtubs. So they're not rather small, are they? No, they're not rather small at all. Those are rather large holes yes well what can you say john lennon obviously didn't do his maths can i just point out that i didn't do any of this stuff there was some other poor sad bugger who did it you may point that out but i'm just going to say i love the fact that you found that out because i couldn't find the answer and i went looking um what is interesting is that coincidentally i i couldn't find proof that this is actually what that line in the song

is about but coincidentally that very same year 1967 the royal albert hall installed all those disc shaped oh the flying saucer thing yeah that's right yeah um to improve the acoustics within the albert hall and coincidentally there are 4 000 odd of them so it may have been a reference to these 4 000 circular potholes looking like those discs in the albert hall who knows yes what other sources oh i suppose there suppose there's food, isn't there? There's food with holes. There is always food, yes. Cheese. Yes. Cheese has holes.

Cheese does have holes. Do you know why cheese has holes? Well, I should know why cheese has holes, because I feel like we covered that in our episode on cheese. We may well have done. But it was so long ago, I can't remember. I don't think we found this out, though. Go on.

Which is that for years it was believed that it was bacteria that were forming the holes okay latest scientific research has suggested that it might be hay little particles of hay hay that are causing the holes in cheese right why is there hay anywhere near the cheese i don't know paul it accidentally falls into the vat while they're making it. I have absolutely no idea. How very odd. But I do know how they get holes into doughnuts.

Go on. Well, they don't, do they? No, they don't. But you can buy doughnut holes, apparently. Can you? There's a sort of a little bit of cake, which is like a bit of doughnut, like just a round thing of doughnut. That looks like it came out of the middle of a dough as if to say that the donut was solid and they extracted the center

from every single one of them to form a perfect hole exactly they did that with polos as well didn't they remember you could buy pots of polo holes which were lovely they were just you know these tiny little blobs of polo yes that's true i've forgotten about polos and lifesavers and all those other things that have holes in them. Yes, yeah. Okay, spare at the moment any other foods that have holes in them. Oh, hang on. Holy foods. Toad in the hole?

Well, yes, technically. It's a whole food. Yes. Brilliant. Donuts are quite interesting to physicists. Are they? Well, they believe that it may be that the universe is donut-shaped. It's called a torus.

Oh, I see. So the reason why it doesn't have an end, why the universe has no end, is because it's actually circular. Oh, yes. Okay. And I was watching QI, and they were talking about holes. And somebody talks about how many holes do you get in a rubber ring? Oh, that rings a bell. And the answer is two.

So there are two holes in a rubber ring. There's one through the middle of the rubber ring, but the other hole is the hole that goes all the way around the inside. Yes, that's right. Yes, the space, the air inside the thing, yeah. Yes, and that's definitely this idea of a Taurus. Okay. Actually, while we're in space, again, there's a hole on Mars. Oh, is there?

Which they've just spotted. Right. Because they've got such high resolution on their cameras now. And they've spotted a hole. It's basically like a hole in the crust of Mars that you can see into Mars. Oh, gosh. And they don't know whether it's the impact of an asteroid or if it's just subsidence that's kind of opened a hole. And so you can actually see into the inside of Mars.

But it is cool that it's in an area of mars which has what they call swiss cheese terrain what about um sound holes sound holes yes what's that f holes o holes things like that i have no idea it all sounds terribly rude it It does. But it isn't. I mean, if you think about violins and guitars. Oh, sound holes. Yes.

Right. You've got to have a hole for the sound to come out. Yes, you have. And the shape of the letter F on a violin is very specific to allow the sound to come out in a pred a predetermined way okay as as is the hole in a guitar yeah it's it's you know it's very important yeah so if you don't if you don't have the hole it just sounds well picture playing an electric guitar without plugging it in it doesn't really make an awful lot of noise well electric guitar is okay because you because you don't need a sound hole for electric guitar but an acoustic guitar absolutely needs a sound hole yes totally i wonder what what who who first came up with the idea of the the f shape on a violin then do you think they tried various other shapes and

other letters maybe maybe they well i mean given the the f is used in musical notation it could be that they could have tried like a bass clef. Yes, a P, all sorts of different shapes. Yeah. Oh, how interesting. I had my voiceover sound engineering hat on when you said sound holes. And I thought, this is a technological term about having gaps in your audio waveform that I don't know about. And am I about to be really embarrassed because I've never heard of them? So I'm glad it was that. Yes, no no it was just

that right fine i had a look at um golf holes right um this this was really odd i went on to a particular search engine others are available but you all know the one i'm talking about and looked up facts about holes and it just kept on coming up with more and more and more facts about golf, as if golf holes were the only type of hole in the universe. And I have no interest in golf whatsoever. But because it just kept on recurring, I thought, well, I better write some of this down. England has, just England, not the UK, just England, has roughly 2,270 odd golf courses in it, not including crazy golf. And of those courses, some of them have nine holes, some have 18 holes. There are a total of 31,620 individual golf holes in england uh there's a standardized size for golf holes which was

introduced in 1891 by the royal and ancient golf club of st andrews of course it was brilliant name um and they standardized the golf hole to four inches deep and four and a quarter inches in diameter and i found um a wonderful little video of how golf holes are made which again we will put a link to on the website you there's a device called a golf hole cutter and it's a circular cutter that they hammer into the ground and it just sort of pulls this plug of earth out of the ground they drop a little plastic cup into it and sort of nest you know again sort of hit it hit it down so that it's nestled in there quite tight so you get that nice sort of net that noise when the yes exactly that's there exactly um but the cup generally sits sort of an inch below the surface

of the soil so that it's you know really nicely embedded in there and doesn't shift around and you get this little bit of white plastic trim that sits atop the cup so that the edge of the hole is firmly in place and doesn't crumble in etc etc um you know they move the holes no what no so so so you can so you basically what you do is you make another hole right and then the stuff that you take out of the other hole you put into the hole that was there before. So it means that each time you play golf, you have to assess the green to sort of check how your putt should go. No way. Because otherwise you get used to the way that the green runs. Do you know how often they do that?

I don't. I just know that they do it. That's brilliant. So you could have that particular hole, excuse the expression, but down to a tee. And then the next time you go and play there, they moved the hole yes oh that's brilliant it's a way to keep but you still know where it is because there's a flag it's a good big big flag yeah sure but still it's um how interesting i didn't know that how do you feel when you see holes? A bit empty, really. You don't feel scared or anything? I mean, it depends on the size of the hole.

If I walked up to a whopping great canyon or a gorge or something, I suppose it could be a little bit intimidating. But if you see lots and lots of small, equally spaced, equally sized holes, it doesn't get to you? No, I don't have an issue with that. So what you don't have is trypophobia no unless it's a phobia of tripping over things it's a fear of repetitive patterns so especially towards holes right so holes repetitive patterns protrusions um so a lot of people if they see a series of repetitive holes, like on a cheese grater or something like that, that makes them nervous. Oh, right.

I think, yes, I seem to remember the texture of the surface of a golf ball since we're in golf. Yes. Because there are lots of little repeated dimples in the ball. And it just sort of sets these people's teeth on edge and makes them feel really uncomfortable. Yes. So they probably won't play golf. Probably not. No.

We've talked about gravity and holes. But you don't have to go that far to find a gravity hole. Don't you? Not really. If you go sort of south of India. Right. There's a thing called a gravity hole. It's called the Geoid Low. Okay.

The Indian Ocean Geoid Low. It's a gravity anomaly in the Indian Ocean. It's basically that the country of India used to be a few hundred miles south of where it currently is. And then when the tectonic plates moved millions of years ago, India moved up into Asia. So sort of the Indian plate moved India moved up into Asia. Yeah. So sort of the Indian plate moved to join the Eurasian plate. But where it was, was very deep. And actually it was quite a thin crust on the Earth that would normally sort of protect the crust of the Earth

from the gravity pull of the core. Okay, right. But the gravity pull of this region is weaker than normal by about 0.005%. Is it really? Yes. Wow. Is it notable? I mean, do you actually sort of feel a little lighter on your feet as you sail past? I doubt it. I mean, 0.005% is not a lot. Not a lot, but still. I mean, it must have been enough for thousandths of a percent is not a lot. I mean, it's not a lot, but still.

I mean, it must have been enough for someone to notice it because it's measurable. Yes, I suppose so. Somebody did notice it. Yeah. It was in 1948, a Dutch geophysicist called Felix Meines. Right, okay. And he was doing a gravity survey on a ship in 1948, and they noticed this. And it wasn't until May 2023 when it was explained away using computer simulations and seismic data wow

there's a hole called mel waters hole mel waters hole mel waters incredible hole okay there's a guy who rang into a radio show and he said that there was a seemingly bottomless hole on his property. Right. And he wouldn't say exactly where it was, but he said it was roughly nine miles west of Ellensburg in Kittsburg County, Washington. Right. And according to him, the hole was an open secret and locals have been dumping stuff there for centuries. And they've been calling it the devil's hole and all sorts of things. And nobody really knows if it actually exists because he made lots of claims about it right he said that it brought pets back to life they sort of lower pets you know a bit like sort of pet cemetery right okay

um they reckon it had uh that metals would change into other metals and sometimes you'd hear strange voices and music from times gone by but the other locals just use it to dump rubbish in yeah i mean this guy mel unusual man yes it sounds so um he said that he lowered a bucket of ice into the hole and it came back warm but still solid and flammable. What? This is a very odd hole. Yes. So Mel's hole is a big deal in this area. And it's like the Loch Ness Monster. Yeah. It's like nobody's ever found it. Nobody really knows who Mel was. Yeah. How wonderful. I know. I love stories like that. I've only got one more fact about holes have you I'm completely out so what's your last one well because I was thinking about making holes so I've got I've got a machine that makes holes to make ring bound um books okay so it makes holes in paper right that's called a hole punch isn't it

it is called a hole punch yeah or a hole puncher or a paper puncher. Yes. And it was invented by a German. Of course. Of course. It was invented by a German about 138 years ago. Right. And it's a very simple mechanism.

He tried to get a patent on it but couldn't. Right. At the time. But you get single hole punches,et punches paper tape repair punches there's all sorts of things that make holes and stuff i mean you and i probably remember that when we were filing stuff at school yeah and putting it into a file yeah you had you had one of these things that made two holes in the in the paper i do i think i still own one i think i do too i think it's about one of the most nicked things at the office yes And then you had those little... I think it's one of the most nicked things at the office. Yes, it probably is.

And then you had those little sticky-backed ring-shaped things, hole reinforcers. Yes, that's right. You sort of stuck around the hole to... Stop them from tearing. Stop them from tearing, that's right, yeah. Yes. Oh, school days. I think that's it then for holes, isn't it?

I think so. I think we are all done. Fantastic. Well, I hope you enjoyed this episode about Holes. Absolutely. And if you did, you know what you could do? How about giving us a five-star review? Oh, that would be lovely.

And do it right now. Yes. We'll be here when you get back. Yeah, yeah. We'll just put it on pause. We'll wait a few seconds. Yeah, don't worry. Here you go.

Come on. Done it? Done it. Great. Excellent. That's really good. Thank you for go. Come on. Done it? Done it. Great. Excellent. That's really good. Thank you for that. Well done.

And have you told your friends? I mean, don't have to do that now. You can do that at dinner parties or something. Yes, we won't wait for you to do that one. Just mention it in passing. What else can they do, Simon? They could also subscribe to this wonderful podcast so that they can get a lovely notification every week to say a new episode is out.

And of course, if you've spotted a glaring hole in what we've been talking about, then by all means, write to us at hello at Factory.com. Indeed. Or leave a comment on our Facebook page. Yes, please do. We are on a constant journey of learning. So if you've got anything to correct us about, please let us know. And we know we're not infallible. No, we're not.

Not at all. So thank you for coming along for another fun-filled episode of... Factorially. Please come again next time. Bye-bye. Au revoir.
