Havent read the books nor watched the 2 new movies buuut played the rts not the new shitty 4xgame but the one from 80s 90s, this makes sence because of how to create spice, your unit got killed by the worm well now there is spice on the ground, I miss the old rts style of currentcy like how this happend and how tibirian grows, chopping down tree ect.😅
Ive never seen/read Dune, but that was my assumption, vibrations would turn the sand into a pseudo liquid like state. Makes a lot more sense than movement based on constant defecation.
If you look closely in the second film. There’s air holes under the scales. So maybe it pumps air at such a pace that it makes the sand fissure (similar in that video with mark rover) along with the sand falling into it’s mouth.
They vibrate the sand around them causing the density of sand to decrease. In short the sand around the worms works like water and they just swim through it.
Also this is not asking how they are able to move through sand, snakes and worms can do that in real life, it’s asking also how do they move in straight lines at such high speed
@@chasehorton2324 only very front of a sandworm is exposed to the ground. Imagine a train with an engine on the back. It's very possible they move their tail to glide through with their head. And about shitting sand thing I don't think it's possible. Because we have seen the tail of a sand worm. (Young sand worm) In Dune 2 when a lady shows Paul's mother how they extract the water of life (that blue water poison thing) it appears like the sandworms tail is like a snake point. To move at that speed they basically need a hole at the back too to eject sand and to create drag.....
It is said that Spice is a byproduct of the sandworm's digestion of the sand and it is shown in the most recent movies that they vibrate themselves or the sand at high frequency to loosen the sand. So they move by vibrating the sand so it is water like inhaleing the sand and passing it at high speeds to propel themselves.
And If it's turning the sand into a water like consistency, its entirely possible it utilizes a version of a squid's siphon, the sand it eats when eating prey is what turns into spice but the sand it consumes for locomotion it will expell it along ports in it's Carapace.
...no... sand trout are microscopic creatures that gorge on water forming a living shell around water deposits. They grow into small worms from the size of eels to dogs, the byproduct of consuming the water which is poisonous to adult worms but safe to juveniles, begins to produce gas, when the gas reqches a zenith it explodes upward exposing the dead and dying youngn sandworms to the sun which bakes the liquid leaving only spice behind in a condensed state. Paul takes the death liquid of a large juvenile as a concentrated drink to trigger his vision.
i always thought that they would vibrate to make the sand around them move and “soft” so then they can go through easily, it’s like sand pools or something like that
It’s actually interesting, they vibrate the sand and “swim” through. Vibrating loose sand has similar properties to water. It also makes a good way to trap people by causing them to sink
Except if that’s how they moved they wouldn’t be going forward, they’d be going straight down. and even if they could generate thrust they couldn’t go up because the sand would just move out of the way instead of making a ramp like a hard object. (they also wouldn’t be able to leap out of the ground)
@@stickmaster400 mark rober has a great video about how the loose vibrating sand acts almost identical to water, so imagine the sand as water and the worm as a whale, it swims through the sand and uses momentum to breach above the sand(watch his video to see what I mean)
@@darthdavid2275 im sure it’s probably good but whales usually can’t maintain floating on top of water like dune worms can, and they have limbs to push them through the water, a better example would be water snakes but if a dune worm thrashed to move like them or flapped its tail like whales then it would cause huge disturbances that would obviously be visible as malformations long before they showed up
My take from what I could see in the movie is that they're more like very large fish. The worms are very large and the sand looks like it goes from inside the mouth to jetting out of the soft tissue underneath the chitinous plates of the worm as spice. Visually for me it's almost alluding the probability that the worms have gill like filters that ejects the spice after ingesting sand and the movement reaction is a byproduct of the spice production and it would also explain why the worms die in water because it's exactly the same as taking a fish out of water. No offense to the scientists that made their conclusions but it feels like they didn't watch the movie at all and that they just heard the word worm and saw Paul riding on the back of it in the trailer and just ran with that
It's basically shown in the movie. When the sandworms are close to the surface, the sand around them turns into somewhat of a liquid and can be easily moved through this is caused by the sandworms natural sounds that they make which causes the sand around them to violently vibrate causing the sand to liquify, the coarser the sand grains become, the longer duration of vibration loading is required to reach the liquefaction state making the sandworms be able to travel underground as fast as they do
In the books, they have itty bitty hairs that independently help propel themselves, they use the sand itself both in their mouths pushing it out in between their scales and on the outside of the body it's stated to move like water around them. Finally, they vibrate at a frequency that maneuvers the sand around them. BTW the byproduct of the sandworm moving through the sand is spice.
Dude stop spreading false info, spice is not created by that, if you read the book you'd know spice is the result of a worm larva that died before reaching maturity and mummified and dedicated into dust, the reason there are large concentrations of spice to "mine" in beds is cause those are old nests, that's also why the worms don't like people driving big things all over it more so than the less spice ridden parts of the desert, the fremen know this and that's why they respect the large spice beds and try to protect them, its a big part of their deep culture
The worms have little to do with spice production at that stage. Spice is created by sandtrout (had to google their name) coming into contact with water. This is why Arrakis is a desert planet, because all the water is converted into Spice.
Spice is the result of a dead worm decomposing under the sand. The gasses from the decomposition build up under the sand and eventually explosively eject to the surface, exposing the spice, which can then be harvested.
@@BingQilin lol glad I didn't disappoint. I haven't read that book in a long time and I didn't think to look it up, so I could have easily misremembered. 😅 Edit: apparently I did misremember. Not a result of sandworm decomposition, but a product of the digestive tracts of sandtrout, and a pre-spice mass is what happens when these excretions from the sandtrout mix with water and eventually explode to the surface. Whatever sandtrout survive the Spice blow would grow into sandworms over the course of thousands of years, and when a worm died, it's body released millions of sandtrout into the surrounding area. So, in an indirect way, spice is the result of the death of a sandworm. 🤷♂️ Edit 2: and, in a way, also sandworm shit...🤷♂️
The books explain it. They move using their scales and vibration. Each scale segment can rotate almost 360, when the worm riders hook the scales it exposes sensitive nerves to the sand and the worm rotates that scale away from the ground, raising the riders up and preventing it from burrowing. They inhale the sand intentionally and filter out sand plankton to eat while the sand is ejected from gill like vents around it's body. Bonus: Life cycle of a worm - Sand plankton -> Sand trout -> Juvenile worm -> Great worm sheds sand plankton. The sand trout stage makes them seek moisture and envelope it. As their mass grows a chemical reaction starts and they become highly allergic to moisture. Critical pressure causes an explosion. The survivors have now metamorphed into juvenile worms and the rest of the bits pushed to the surface dry out to become spice.
@@youngwindmillgang3239 right, spice is a drug that is produced by the worms when they are in the sand trout phase. The sand trout produce a substance that combines with water in the sand, which then rises to the surface and is turned into the spice by the heat and dry air
Came to comment that instead of watching a movie and guessing he should read the books and was gratified to find someone beat me to it. And quite thoroughly, to boot.
@@thomast7794 Its also used in food as an actual spice. It prolongs people's lifespan and causes prescience in some including the guild navigators which is why they're able to do interstellar travel.
Spoilers from "Children of Dune" The idea of sand worms being like rockets that propel themselves forward from eating sand might not sound as crazy if you read far enough. It reminds me of this quote from Children of Dune describing a worm-rider who knows to avoid the worm's tail as he dismounts: "...the excesses of the creature's heat-transfer system still churned up a cyclone oven behind him in the quickening storm. Fremen children learned the dangers of this position near the worm's tail with their earliest stories. Worms were oxygen factories; fire burned wildly in their passage, fed by the lavish exhalations from the chemical adaptations to friction within them."
Unsolicited Physicist here, they definitely don't suck and poop sand. The director is on record as saying that at least in his interpretation they vibrate and cause the sand near them to act as a fluid (since the particles will have more energy and can move around eachother without getting stuck) that is much easier to move through, Google fluidized sand bed to check it out! (hopefully this is a purposeful troll and not actually claiming to be physics) kthxbai!
they have countless small hairs as well as eating sand and pushing out of their scales (basically pooping) it's how they make spice. The sand is taken in, and when it's expelled (as worm poop) it has the properties that make spice valuable. This is from the book iirc.
Yes, they vibrate to make the sand act like a liquid, but that still doesn’t explain how they can zoom through that liquid sand at such a high rate of speed
@@jonahfiegel8755 Sure it does. They control the vibration, as in vibrating more above/in front of them versus less below/behind them. Also, they're huge, amplifying the effect to let them move faster. If they were human sized, they'd move slower. Look up those sand beds the commenter talked about. It lets stuff move through sand pretty quickly.
It's explained as: "They move through the sand using a combination of rhythmic undulations and the secretion of a natural lubricant that allows them to travel smoothly through the granular surface. This movement is described as almost graceful despite their massive size, and they can travel at considerable speeds when motivated, often propelled by the sound or vibrations of nearby activity. Their movements are crucial to the ecosystem of Arrakis, as they help aerate the soil and distribute water, playing a vital role in the planet's desert ecology."
one of the other possibilities is the worms use the same motion our digestive track does when we swallow in order to push sand backwards around them wich will make them go straight and not inhale sand
Rapid vibration makes sand liquid like. If they rapidly vibrated or somehow emitted sound waves they could effectively swim in the sand or on the sand. Maybe?
In the first movie, their movements were scientifically sound. They moved through the sand similarly to sand snakes on earth . But to my understanding there was a different mechanism they used to move in a straight line above the sand
It shows how they move through the sand in the films. As they approach the sand begins to act like a liquid/much like when air is pumped through sand. The clicking sound is them giving the surrounding sand that liquid like characteristic.
@ArvinYorro Think of whales in the ocean. They suck in tons of water when consuming plankton. Sandworms consume tons of sand and deficate spice. The Spice mine platform's float down veins of Spice much like oil rigs in Saudi. The desert in dune is pretty much sewage, as the worms consume so much sand and poop it out that under the surface is basically just Spice which is not as dense as sand. This makes the worms more akin to whales than worms.
I’m pretty sure that the idea for the sandworms is that they are pumping air out of their flaps which, as shown in that one mark rober video, gives the sand liquid-like properties
That is THE MAIN thing lol. that's why they are at it. The spice are the Worm's poop.. that's why they don't really go out their way to kill the worms. cuz without them they won't be making spice.
For real. Herbert explains in the books why the work isn’t turning. The segmented worm has had a segment forcefully opened by the fremen hook thereby creating a vulnerability for sand to make its way into the worm. To combat this the worm turns “hook upward;” this is the whole principle behind worm riding.
His last description is the correct one as far as I understand from the books. Because the spice comes from the excretion of the sandworm after it eats the sand. So that's how they move and how we get spice
It is explained that the sandworms do eat sand, but not to move, because spice is a byproduct of sandworms digestion when eating sand. However, they move by vibrating their scales at such a speed and force that the sand around them is at a consistently similar to water, and they just swim through it.
it wasn't until we realised that air behaves a lot more like a liquid at insect scale and thus that bees & other flying insects are actually using their wings essentially as paddles to swim through the air that we realised applying our model of lift:weight ratios was flawed, but yeah, I agree with your point, just bc our science hadn't caught up doesn't mean its impossible (although this is a Sci fi concept so we can probably conclude that it's functionally impossible for something this big to swim through sand as fast as the Dune sand worms do... until we see one do it of course)
@someguy9164 I'm saying if they where real there would be a physics explanation for them that we don't necessarily understand just like we didn't understand bees
While the origins of "scientists say bees shouldn't be able to fly" myth is uncertain, it's 100% a myth. A meme from long before that word was around. If anything that story (if it ever had any kind of origin in reality) demonstrated a gap in knowledge, which is *not* the same as denial of fact. Not knowing how bees fly but being fully aware that they do so is not saying that physics told us they can't fly, but that we lacked key information. The difference is massive. Phrasing is important if one wishes to avoid spreading anti-scientific sentiment.
@HellaGust known physics told us they shouldn't be able to fly. Obviously they could fly so it was a gap in knowledge. If you need everything spelled out to you exactly then you are an insufferable prick.
And surprisingly many many years after a book which actually explains this came out. Woah, he's the modern cristopher columbus. He discovered something many many people knew about way before him.
Or their backs could be a hard carapace that doesn’t really move but their belly could be a series of movable plates that can move closer and further away from each other. If they could also pivot out a bit then that would even give quite a bit of traction for moving in the very loose sand, kind of like how a paddle tire does but instead of rotating like a wheel it is more of a stretching and contracting thing.
@@perryjohnson7529 I'm not a dune expert, so I could be wrong. Feel free to correct me if I am. I did just finish God Emperor of Dune last week for the first time. Many times in the book it said that even moisture in the air was painful and unsettling to Leto II. Another part in the book where Leto II is in his desert, it said he would eat till he was content. Also, when he was testing Siona, she asked if he ate the sand and he replied that he did.
That method of movement would also explain how the material called Spice is created. Its said that Spice is a byproduct of those sand worms. Maybe Spice is sorta like the Ambergris is for whales.
Potential spoiler Spice is a byproduct of the larval state of the sandworm, which absorbs water to the point that they can singlehandedly decimate environments. Eventually the high consentration of larval sandworms causes what is called a spice blow, where pressure causes sand and spice to explode into the air resulting in a chemical reaction when the spice oxidizes
I think they have small holes on each side of plate so then when they get the sand and they blow it out like a little sand jets as it pushes them along
Option 3 plus their outer carapice vibrates to create osicaltions that makes the sand like liquid. they're essentially moving furnaces with all the friction and it's part of their anatomy. the friction from all their movements make their inner maw red hot and this catalytic process procues ozone which they eject. I'm assuming with that pressure they can rocket themselves with their poop/waste as you say expelling it from from ducts in their outer carapace. There's more to it than that, just a causal fans recollection for quick answer.
The problem with the films is that they did not really do their homework. The dune encyclopedia (endorsed and contributed to by Herbert) talks about how sand worms move through the sand using rhythmic contractions that create waves like how a snake moves. They also expel gas around them to not only control the depths at which they travel, but also loosen the sand around them very much like the concept for a super cavitating torpedo.
you're forgetting the vibrating that makes the sand act like a fluid. And i feel like the movies got the sandworm quite right actually because they show the sand vibrating (and people sinking in it showing that it has become fluid-like), they also show the little vents on the sides of the scales from which the worms can expel air and sand they swallowed (those are shown better in 2nd movie though)
They showed air vents under their flaps in 2 and explained how they use vibration to move and loosen the sand in 1, think you didn't do your homework lol
To be fair they tried to convey some of that, in a channel called Corridor Crew they interviewed one of the directors or artists. He said that they where trying to show all of that and in the movies the inside of the mouth of a sandworm is based on the throat of a beat boxer, so the worms are making some vibration
Snakes generally don't use wriggling as their method of propulsion. It is a rhythmic contraction of the muscles on their belly that causes the scales there move closer together or farther apart, just like an earthworm. This is how burrowing snakes dig their burrows. The scales on the dorsal side barely move while the scales on the belly move quite a bit.
There's a very large amount of snake species that, to use your word "wriggle" for movement. It's just that nobody with any idea of what they're talking about describes the movements snakes make as wriggling. They slither. Typically bigger snakes motion is called Rectilinear Progression. There's like 5 different types of motion various snake species use but using their scales is not how they move, it's how a certain species of snake burrows.
@gdub19777 that's exactly how every snake I've had has moved. I have owned 3 python species, a boa, and a hand full of different colubrid species. Rectilinear motion is extremely common in ground dwelling snakees.
could also be the premise behind liquid sand. Their scales could aerate the sand to cause it to flow like water and then use the vibrations to move through it
Alternative theory; it could be like how the tremors move, they have several fin-like protrusions that can be moved, so they can push and essentially swim through the sand.
Antlions. Look it up, also they cannot stand on the dune while it approaches due to the sand liquidating as the word approaches due to sound/vibration. These are real physics, except when he stands on the dune, not a rock.
The last option is implied in the books - because the spice melange is created by the worms. The worms were brought to Arrakis and created the spice through expulsion of the sand.
U can also achieve movement like this with vibration and frequency. Maybe it vibrates at a rate that vibrates the same to the point of a quick sand effect where the sand kinda starts to become like buoyant and water like.
The vfx team that worked on the new movies based the inside of Shai Hulud’s mouth on footage of a beatboxer’s throat because they wanted to convey that the worms use their vocal vibrations and oscillations to liquify the sand around them and allow them to flow through it with ease. You can even hear their loud voices right before the first sandworm that Paul rode on made contact with the dune he was standing on, and when the sandworms appeared out of the smoke after Paul and the Fremen used the family atomics.
I believe since they are able to feel the vibrations from the footsteps of animals on sand, this suggests that they are hyper sensative to vibrations. Animals that big would only develop vibrational sensativity due to need. Since they don't actually "Eat" creatures for food, They eat the spice found in the sand, It would suggest that the need is to communicate with other worms or to locate worm trespassers into their territory. This means that vibrations are so common to the worms that they have developed a highly sensitive sense to effectivly "Feel" their surroundings. Therefore, their means of locomotion would be vibrational in nature since the most common way to detect competion would be through sight, but they dont have eyes, or hearing, but hearing only works to a point, but feeling others, thats the best way in their environment and why would you devvelop sensitivity to vibrations unless your biggest competition used vibration frequently. Also whenever a worm gets close you literaly see the sand vibrate into a state of semi liquidness.
Just because their top portion is stabilized, doesn't mean their bottom portion is. People could ride on the top portion that has a more fixated position while the remainder portion of the worm is contorting in all kinds of ways to move the work forward.
Each scale segment can be rotated independently. The hooks the worm riders use pull the scale back to expose sensitive nerves to the sand, causing the worm to rotate that scale away from the irritation and also preventing it from burrowing again so long as the nerve is exposed. Exposing nerves near the head is how they cause it to turn and "steer". The books explain it and how the worms move.
they actually Remade the Dune Movies, part two just came out, in part one they go to great lenghts showing and explaining how the worms move. can reccomend them both!
Entry from Stetmann's Zerg sample research: "I'm learning how some zerg burrow as well. It's extremely sophisticated. They have billions of tiny muscles that vibrate at a low frequency, effectively loosening soil, crumbling rock, and snapping vegetation. They can "swim" through the ground. It's not quite as fast as running, but it's close."
It could also be a way to get nutrients from sifting out, microorganisms in the sand. Maybe they have really complex insides and miles of it. That make it possible to sustain them self off of just sand.
My assumption is that they perform a peristaltic motion at a very high frequency like a piezo electric device. Spice crystals could themselves be that piezo crystal that can convert the sand worm's biothermal/bioelectrical energy into vibratory mechanical motion. By controlling the frequency, amplitude and phase, the sand worm can cause the nearby sand to liquify allowing it to glide through the sand like it is water. If a creature of that size can glide through semi solid earth, it has to be ultra sonics! Also ultra sonic vibrations can breakdown even the metals which is how a lot of abrasive operations work - which explains how the worm can eat and process sand and even the spice mining machinery without breaking sweat. Also ultrasonics can perform density sorting of material which allows the worm to separate nutrition, raw spice and waste sand from its intake.
That's where the spice comes from. In the books,Shai'hulud means the maker meaning they make the spice. BH often speaks of the scent of spice like a hot wind. BH was a naturalist and often wrote stories about natural processes so that sandworms are like earthworms is not a stretch.
Now i know that it actually moves through vibration and whatever, but i like to think that just like jet engines have layers of blades spinning to compress air, sandworms essentially have either spinning teeth creating the compression or maybe rotating sphincters
Yeah no shit, these people are aware it's fiction. But guess what? it's Science Fiction. Explaining away the fantastical elements with loose science is one of the major fun people have with this genre. This is how sci-fi fans sit down and enjoy it.
@@Vayne29 basically people can't just enjoy things on the Internet and they have to know how so they make theories and shit and then argue about which one is right But hey idrk if that's right so yeah
I mean they kind of are like rockets: “Fremen children learned the danger of this position near the worm’s tail with their earliest stories. Worms were oxygen factories; fire burned wildly in their passage, fed by the lavish exhalations from the chemical adaptations to friction within them.”
small correction: that would be a sand jet not a rocket. a rocket uses fuel inside itself to propell itslef while a jet uses the air (or and) infront of itself and pushes it out the back at a higher pressure creating thrust
In real life physics i can think of another way that is there skin being like covered in fingers and slowly puching themselver forward or it being flexable skin like in a snail making waves to mover them forward.
People forget, the sandworm is an all powerful creature! A lot of it's characteristics aren't fully fleshed in the movies such as the intense heat that eminates from the worms mouth that can cause plasma to propogate in the immediate area. It also creates powerful lightning and electromagnetic fields at will. Because they can generate such energy, which is needed to move their size and account for the square cube law, I postulate that they are able to use the Holtzman effect to manipulate the environment around them and prevent energy loss. I'm sure Frank would like that idea if he didn't think of it already (which i I think he would have)
Rule number one for Physics in Fiction: Real Life Physics do not matter in a fictional setting unless it is specifically told to us that they do. That rule is why there is sound in space in most sci-fi settings
The sandworms in dune are responsible for the creation of spice. As I remember it involved the ingestion of sand much the same way as when they are drowned in water, they will expel out the blue liquid. That is called the water of life. Another option is that they could have micro movements within their skin, As you see, when Paul holds on 1 side of the worm and it rotates in order to get the sand away from the open area. It's like thousands of coils moving together inch by inch. when you put many of them together in a long line, you get what looks like, the worm not even moving just gliding through the sand.
Blue liquid is the Water of Life -- it's produced when young worms are drown in water, and it's basically Spice essence (Fremen reveal this in "Dune" the book). The Spice spots humans mine on the surface are made when old Worms die, so it's kinda weaker in effect, but still potent enough for humans. Water is poison to Worms, so if Arrakis gets terraformed -- the Galaxy loses Spice. This is the power Fremen hold -- they have millions of hectoliters of water in their sietches' stashes, all ready to be released on command when and where the Messiah says. Worm movement is based off of earth worms -- they eat sand and expel it from behind, filtering out nutrients and the little moisture they need. The "expel from behind" part is not what propels the Worms, it's the "eating sand" part that does. They're pulling themselves through the sand.
I’ve always liked the idea that they creat a very high frequency sound that makes the sand behave like a liquid, then they can propel through it like water
Yes, but the question is HOW are they propelling. Everyone in this comment section keeps pointing out that same fact about them turning the sand liquid but that’s not the issue. It doesn’t change the fact that even in water, animals don’t just dart forward like a torpedo.
@@hiimchrisjthe hell are you talking about fish and whales can most certainly dart in straight line just because they’re back fin/tail is moving from side to side doesn’t mean they can’t move in a straight line. Like I’ve never seen any aquatic animal move from side especially when they’re running from a predator or trying to catch prey
@@sancholoaded2388 yes but the worms don't move their backsides. . .that's the entire point for fucks sake. People need to stop regurgitating the same lines without even understanding the question.
I thought they would vibrate the sand around them making an almost fluidised bed around them basically making them "swim" through the sand. You can see videos of fluidised beds here on youtube.
I think they can still move like snakes. Snakes heads hold while they move so they can just look ahead and see where they’re going, so the same could apply for the sandworm. They just look straight ahead while the rest of their body is moving.
Cool Sand Worm T-Shirt!: amzn.to/4a0SXyF

That explains 2 things. 1. Is the travel. 2. Is the amount of spice left in the sand. If spice is a waste product.
Sand worms could use air coming out there body’s to make the same fluid. Makes more sense that shit rockets.
It's not physics they use but spice. They use the force to move like magic.

They vibrate the sand around them causing the density of sand to decrease. In short the sand around the worms works like water and they just swim through it.
Average people think of this as "it's obvious". But then comes the Americans....
Then they would move the same way as eels and sea snakes. But that's still not the case.
Also this is not asking how they are able to move through sand, snakes and worms can do that in real life, it’s asking also how do they move in straight lines at such high speed

Yep. And that's how spice gets made.
Nope. Spice is made when a group of sandtrout surround a pocket of water. It leads to a spice blow.
It's actually both. The sand trout become way more important when all the large worms die out in the later books. @@robertshaw4717

They grow into small worms from the size of eels to dogs, the byproduct of consuming the water which is poisonous to adult worms but safe to juveniles, begins to produce gas, when the gas reqches a zenith it explodes upward exposing the dead and dying youngn sandworms to the sun which bakes the liquid leaving only spice behind in a condensed state. Paul takes the death liquid of a large juvenile as a concentrated drink to trigger his vision.
i always thought that they would vibrate to make the sand around them move and “soft” so then they can go through easily, it’s like sand pools or something like that
There is a snake that “walks” using its rib cage so it could work like that
The movie Tremors feels like the best explanation of how they move in the sand. It’s a great old movie.
Reminds me of watching tremors when I was like 12 with my dad. Definitely a great movie, anyone who sees this should at least look it up
@@evergreen2721 all of the tremors are free on youtube
No way i had the exact same experience with my dad @evergreen2721
That whole series is gold.
Dude u had the same idea Graboids
It’s actually interesting, they vibrate the sand and “swim” through. Vibrating loose sand has similar properties to water. It also makes a good way to trap people by causing them to sink
Except if that’s how they moved they wouldn’t be going forward, they’d be going straight down. and even if they could generate thrust they couldn’t go up because the sand would just move out of the way instead of making a ramp like a hard object. (they also wouldn’t be able to leap out of the ground)
well maybe they only vibratd the sand close to their skin idk@@stickmaster400
@@stickmaster400 mark rober has a great video about how the loose vibrating sand acts almost identical to water, so imagine the sand as water and the worm as a whale, it swims through the sand and uses momentum to breach above the sand(watch his video to see what I mean)
*Shara'ishvalda flashbacks*
@@darthdavid2275 im sure it’s probably good but whales usually can’t maintain floating on top of water like dune worms can, and they have limbs to push them through the water, a better example would be water snakes but if a dune worm thrashed to move like them or flapped its tail like whales then it would cause huge disturbances that would obviously be visible as malformations long before they showed up
My take from what I could see in the movie is that they're more like very large fish. The worms are very large and the sand looks like it goes from inside the mouth to jetting out of the soft tissue underneath the chitinous plates of the worm as spice. Visually for me it's almost alluding the probability that the worms have gill like filters that ejects the spice after ingesting sand and the movement reaction is a byproduct of the spice production and it would also explain why the worms die in water because it's exactly the same as taking a fish out of water. No offense to the scientists that made their conclusions but it feels like they didn't watch the movie at all and that they just heard the word worm and saw Paul riding on the back of it in the trailer and just ran with that
It's basically shown in the movie. When the sandworms are close to the surface, the sand around them turns into somewhat of a liquid and can be easily moved through this is caused by the sandworms natural sounds that they make which causes the sand around them to violently vibrate causing the sand to liquify, the coarser the sand grains become, the longer duration of vibration loading is required to reach the liquefaction state making the sandworms be able to travel underground as fast as they do
In the books, they have itty bitty hairs that independently help propel themselves, they use the sand itself both in their mouths pushing it out in between their scales and on the outside of the body it's stated to move like water around them. Finally, they vibrate at a frequency that maneuvers the sand around them. BTW the byproduct of the sandworm moving through the sand is spice.
Dude stop spreading false info, spice is not created by that, if you read the book you'd know spice is the result of a worm larva that died before reaching maturity and mummified and dedicated into dust, the reason there are large concentrations of spice to "mine" in beds is cause those are old nests, that's also why the worms don't like people driving big things all over it more so than the less spice ridden parts of the desert, the fremen know this and that's why they respect the large spice beds and try to protect them, its a big part of their deep culture
The worms have little to do with spice production at that stage. Spice is created by sandtrout (had to google their name) coming into contact with water. This is why Arrakis is a desert planet, because all the water is converted into Spice.

Not just jet-pooping sand, but also Spice!!
Spice is the result of a dead worm decomposing under the sand. The gasses from the decomposition build up under the sand and eventually explosively eject to the surface, exposing the spice, which can then be harvested.
@marcz2903 for a second I thought you were gonna say that Spice is basically sandworm shit and I got so scared
@@BingQilin lol glad I didn't disappoint. I haven't read that book in a long time and I didn't think to look it up, so I could have easily misremembered. 😅
Edit: apparently I did misremember. Not a result of sandworm decomposition, but a product of the digestive tracts of sandtrout, and a pre-spice mass is what happens when these excretions from the sandtrout mix with water and eventually explode to the surface. Whatever sandtrout survive the Spice blow would grow into sandworms over the course of thousands of years, and when a worm died, it's body released millions of sandtrout into the surrounding area. So, in an indirect way, spice is the result of the death of a sandworm. 🤷♂️
Edit 2: and, in a way, also sandworm shit...🤷♂️
So giant worm poop is spicy sand 👌
Yeah it says in the books that the worms produce the sand
The books explain it. They move using their scales and vibration. Each scale segment can rotate almost 360, when the worm riders hook the scales it exposes sensitive nerves to the sand and the worm rotates that scale away from the ground, raising the riders up and preventing it from burrowing. They inhale the sand intentionally and filter out sand plankton to eat while the sand is ejected from gill like vents around it's body.
Bonus: Life cycle of a worm - Sand plankton -> Sand trout -> Juvenile worm -> Great worm sheds sand plankton. The sand trout stage makes them seek moisture and envelope it. As their mass grows a chemical reaction starts and they become highly allergic to moisture. Critical pressure causes an explosion. The survivors have now metamorphed into juvenile worms and the rest of the bits pushed to the surface dry out to become spice.
whats spice is that like a drug like jet is in fallout?
Spice is the most important ressource in the Dune universe.
It is a drug necessary for interstellar travel.
@@youngwindmillgang3239 right, spice is a drug that is produced by the worms when they are in the sand trout phase. The sand trout produce a substance that combines with water in the sand, which then rises to the surface and is turned into the spice by the heat and dry air

Spoilers from "Children of Dune"
The idea of sand worms being like rockets that propel themselves forward from eating sand might not sound as crazy if you read far enough. It reminds me of this quote from Children of Dune describing a worm-rider who knows to avoid the worm's tail as he dismounts:
"...the excesses of the creature's heat-transfer system still churned up a cyclone oven behind him in the quickening storm. Fremen children learned the dangers of this position near the worm's tail with their earliest stories. Worms were oxygen factories; fire burned wildly in their passage, fed by the lavish exhalations from the chemical adaptations to friction within them."
There's so many weird animal quirks that this isn't even a stretch
Tremors explained this whole idea for the graboids
Unsolicited Physicist here, they definitely don't suck and poop sand. The director is on record as saying that at least in his interpretation they vibrate and cause the sand near them to act as a fluid (since the particles will have more energy and can move around eachother without getting stuck) that is much easier to move through, Google fluidized sand bed to check it out! (hopefully this is a purposeful troll and not actually claiming to be physics) kthxbai!
they have countless small hairs as well as eating sand and pushing out of their scales (basically pooping)
it's how they make spice. The sand is taken in, and when it's expelled (as worm poop) it has the properties that make spice valuable. This is from the book iirc.
@@blackwoodsecurity531 are you being serious?
That's what I thought too but I gotta say I like the sand shitting rocket worm theory better
Yes, they vibrate to make the sand act like a liquid, but that still doesn’t explain how they can zoom through that liquid sand at such a high rate of speed
@@jonahfiegel8755 Sure it does. They control the vibration, as in vibrating more above/in front of them versus less below/behind them. Also, they're huge, amplifying the effect to let them move faster. If they were human sized, they'd move slower.
Look up those sand beds the commenter talked about. It lets stuff move through sand pretty quickly.
It's explained as:
"They move through the sand using a combination of rhythmic undulations and the secretion of a natural lubricant that allows them to travel smoothly through the granular surface. This movement is described as almost graceful despite their massive size, and they can travel at considerable speeds when motivated, often propelled by the sound or
vibrations of nearby activity. Their movements are crucial to the
ecosystem of Arrakis, as they help aerate the soil and distribute water,
playing a vital role in the planet's desert ecology."
one of the other possibilities is the worms use the same motion our digestive track does when we swallow in order to push sand backwards around them wich will make them go straight and not inhale sand
There's some snakes that use their rib cages in weird ways to move forward in a straight line
Rapid vibration makes sand liquid like. If they rapidly vibrated or somehow emitted sound waves they could effectively swim in the sand or on the sand. Maybe?
Yeah that’s pretty much what the book says
They could maybe swim, but they don't, as evidenced by the lack of movement we see in the movie
I was going to say the same thing and reference the mark grober video
@@Rifterxx5 Mark Goober*

Sandworm said “it’s sandwormin time” and sandwormed all over
I love the idea that colossal worms move the way they do because they have explosive fast acting diarrhea
They prefer to call it "spice explosion"
In the first movie, their movements were scientifically sound. They moved through the sand similarly to sand snakes on earth . But to my understanding there was a different mechanism they used to move in a straight line above the sand
It shows how they move through the sand in the films. As they approach the sand begins to act like a liquid/much like when air is pumped through sand. The clicking sound is them giving the surrounding sand that liquid like characteristic.
People don’t realize Frank Herbert actually put thought into every part of the Dune universe, he had a real explanation to how the worms exist
So what was it?
I'm trynna know too
To the Library 📚❤
Sandworms are from Tolkien
@ArvinYorro Think of whales in the ocean. They suck in tons of water when consuming plankton.
Sandworms consume tons of sand and deficate spice. The Spice mine platform's float down veins of Spice much like oil rigs in Saudi.
The desert in dune is pretty much sewage, as the worms consume so much sand and poop it out that under the surface is basically just Spice which is not as dense as sand. This makes the worms more akin to whales than worms.
You forgot option 4, just like the rock in SpongeBob, it just goes.
We used to ride these babies all the time in the pioneering age
greatest headcannon
Well, the last option fits in with the lore of how spice is made
I’m pretty sure that the idea for the sandworms is that they are pumping air out of their flaps which, as shown in that one mark rober video, gives the sand liquid-like properties
This entire planet's sand is 99% Dune Worm poop.
That's essentially what spice is
So? 99% of our planet's water is fish pee.
@@Xaxp And the air is 21% tree breath
No one tell him about earthworms... 😉
That is THE MAIN thing lol. that's why they are at it. The spice are the Worm's poop.. that's why they don't really go out their way to kill the worms. cuz without them they won't be making spice.
Man did no reading before posting this
Right?
Could you explain I haven’t watched or read dune
@@YourLocalNerd1I believe they oscillate their scales to move forward
For real. Herbert explains in the books why the work isn’t turning. The segmented worm has had a segment forcefully opened by the fremen hook thereby creating a vulnerability for sand to make its way into the worm. To combat this the worm turns “hook upward;” this is the whole principle behind worm riding.
@@YourLocalNerd1it’s very clear that the author hasn’t read or paid much attention to Dune.
His last description is the correct one as far as I understand from the books. Because the spice comes from the excretion of the sandworm after it eats the sand. So that's how they move and how we get spice
It is explained that the sandworms do eat sand, but not to move, because spice is a byproduct of sandworms digestion when eating sand. However, they move by vibrating their scales at such a speed and force that the sand around them is at a consistently similar to water, and they just swim through it.
Physics also told us bees couldnt fly until we figured out the way they moved their wings
it wasn't until we realised that air behaves a lot more like a liquid at insect scale and thus that bees & other flying insects are actually using their wings essentially as paddles to swim through the air that we realised applying our model of lift:weight ratios was flawed, but yeah, I agree with your point, just bc our science hadn't caught up doesn't mean its impossible (although this is a Sci fi concept so we can probably conclude that it's functionally impossible for something this big to swim through sand as fast as the Dune sand worms do... until we see one do it of course)
@someguy9164 I'm saying if they where real there would be a physics explanation for them that we don't necessarily understand just like we didn't understand bees
While the origins of "scientists say bees shouldn't be able to fly" myth is uncertain, it's 100% a myth. A meme from long before that word was around.
If anything that story (if it ever had any kind of origin in reality) demonstrated a gap in knowledge, which is *not* the same as denial of fact. Not knowing how bees fly but being fully aware that they do so is not saying that physics told us they can't fly, but that we lacked key information. The difference is massive.
Phrasing is important if one wishes to avoid spreading anti-scientific sentiment.
@HellaGust known physics told us they shouldn't be able to fly. Obviously they could fly so it was a gap in knowledge. If you need everything spelled out to you exactly then you are an insufferable prick.

@@MonerLaine jeez you sound unbearable to be around
@@MonerLaine 1) Pedantic AF
2) Who reads books these days?
@@MonerLainethe book has a completely different explanation. This video is just dumb
Another idea is that they have little holes underneath their scales. And they use these to force air or sand out
Or their backs could be a hard carapace that doesn’t really move but their belly could be a series of movable plates that can move closer and further away from each other. If they could also pivot out a bit then that would even give quite a bit of traction for moving in the very loose sand, kind of like how a paddle tire does but instead of rotating like a wheel it is more of a stretching and contracting thing.
That makes sense about how spice is actually created since later on in the books we find out that spice is actually worm poop
lol I was just about to comment this. That they literally eat sand and poop it out as spice. So sand rocket isn’t entirely wrong.
I was saying "that's what spice is" when he was talking about the worms pooping out sand.
Had to scroll to far for this comment.
If I remember correctly, they eat moisture. It's been over a decade since I read God Emperor of Dune though.
@@perryjohnson7529 I'm not a dune expert, so I could be wrong. Feel free to correct me if I am. I did just finish God Emperor of Dune last week for the first time. Many times in the book it said that even moisture in the air was painful and unsettling to Leto II. Another part in the book where Leto II is in his desert, it said he would eat till he was content. Also, when he was testing Siona, she asked if he ate the sand and he replied that he did.
That method of movement would also explain how the material called Spice is created. Its said that Spice is a byproduct of those sand worms. Maybe Spice is sorta like the Ambergris is for whales.
Potential spoiler
Spice is a byproduct of the larval state of the sandworm, which absorbs water to the point that they can singlehandedly decimate environments. Eventually the high consentration of larval sandworms causes what is called a spice blow, where pressure causes sand and spice to explode into the air resulting in a chemical reaction when the spice oxidizes
No, read the spoiler
I think they have small holes on each side of plate so then when they get the sand and they blow it out like a little sand jets as it pushes them along
T
Option 3 plus their outer carapice vibrates to create osicaltions that makes the sand like liquid. they're essentially moving furnaces with all the friction and it's part of their anatomy. the friction from all their movements make their inner maw red hot and this catalytic process procues ozone which they eject. I'm assuming with that pressure they can rocket themselves with their poop/waste as you say expelling it from from ducts in their outer carapace. There's more to it than that, just a causal fans recollection for quick answer.
The problem with the films is that they did not really do their homework. The dune encyclopedia (endorsed and contributed to by Herbert) talks about how sand worms move through the sand using rhythmic contractions that create waves like how a snake moves. They also expel gas around them to not only control the depths at which they travel, but also loosen the sand around them very much like the concept for a super cavitating torpedo.
you're forgetting the vibrating that makes the sand act like a fluid. And i feel like the movies got the sandworm quite right actually because they show the sand vibrating (and people sinking in it showing that it has become fluid-like), they also show the little vents on the sides of the scales from which the worms can expel air and sand they swallowed (those are shown better in 2nd movie though)
I feel like everything you're describing could be implied by the movie especially the expelling through the skin
They showed air vents under their flaps in 2 and explained how they use vibration to move and loosen the sand in 1, think you didn't do your homework lol
To be fair they tried to convey some of that, in a channel called Corridor Crew they interviewed one of the directors or artists. He said that they where trying to show all of that and in the movies the inside of the mouth of a sandworm is based on the throat of a beat boxer, so the worms are making some vibration
Unfortunately, the encyclopedia isn't canon after Brian got his hands on his old man's work.
Snakes generally don't use wriggling as their method of propulsion. It is a rhythmic contraction of the muscles on their belly that causes the scales there move closer together or farther apart, just like an earthworm.
This is how burrowing snakes dig their burrows.
The scales on the dorsal side barely move while the scales on the belly move quite a bit.
Yes, BUT that physically wouldn’t work on the scale of those worms, biomechanically
There's a very large amount of snake species that, to use your word "wriggle" for movement. It's just that nobody with any idea of what they're talking about describes the movements snakes make as wriggling. They slither. Typically bigger snakes motion is called Rectilinear Progression. There's like 5 different types of motion various snake species use but using their scales is not how they move, it's how a certain species of snake burrows.
@aufstieg6948 and why not?
@gdub19777 that's exactly how every snake I've had has moved. I have owned 3 python species, a boa, and a hand full of different colubrid species. Rectilinear motion is extremely common in ground dwelling snakees.
could also be the premise behind liquid sand. Their scales could aerate the sand to cause it to flow like water and then use the vibrations to move through it
Alternative theory; it could be like how the tremors move, they have several fin-like protrusions that can be moved, so they can push and essentially swim through the sand.
Antlions. Look it up, also they cannot stand on the dune while it approaches due to the sand liquidating as the word approaches due to sound/vibration. These are real physics, except when he stands on the dune, not a rock.
They are different in shape, form and size.
The last option is implied in the books - because the spice melange is created by the worms. The worms were brought to Arrakis and created the spice through expulsion of the sand.
In Leto's journals he stated he thought the Worms might not be native to Arrakis but I dont think that was ever confirmed as fact.
U can also achieve movement like this with vibration and frequency. Maybe it vibrates at a rate that vibrates the same to the point of a quick sand effect where the sand kinda starts to become like buoyant and water like.
The vfx team that worked on the new movies based the inside of Shai Hulud’s mouth on footage of a beatboxer’s throat because they wanted to convey that the worms use their vocal vibrations and oscillations to liquify the sand around them and allow them to flow through it with ease. You can even hear their loud voices right before the first sandworm that Paul rode on made contact with the dune he was standing on, and when the sandworms appeared out of the smoke after Paul and the Fremen used the family atomics.
I believe since they are able to feel the vibrations from the footsteps of animals on sand, this suggests that they are hyper sensative to vibrations.
Animals that big would only develop vibrational sensativity due to need. Since they don't actually "Eat" creatures for food, They eat the spice found in the sand, It would suggest that the need is to communicate with other worms or to locate worm trespassers into their territory.
This means that vibrations are so common to the worms that they have developed a highly sensitive sense to effectivly "Feel" their surroundings.
Therefore, their means of locomotion would be vibrational in nature since the most common way to detect competion would be through sight, but they dont have eyes, or hearing, but hearing only works to a point, but feeling others, thats the best way in their environment and why would you devvelop sensitivity to vibrations unless your biggest competition used vibration frequently.
Also whenever a worm gets close you literaly see the sand vibrate into a state of semi liquidness.
The spice is created by them, they don’t eat it. It’s a waste byproduct of their larval stage. The sand plankton.
If I remember correctly..Graboids (from Tremors) had the same method..feeling vibrations and listening for any noise before attacking

People could ride on the top portion that has a more fixated position while the remainder portion of the worm is contorting in all kinds of ways to move the work forward.
Good call. Prime example of this is the way a gaboon viper moves
This is literally exacrly what I came to comment. Glad I read down before pressing send
Each scale segment can be rotated independently. The hooks the worm riders use pull the scale back to expose sensitive nerves to the sand, causing the worm to rotate that scale away from the irritation and also preventing it from burrowing again so long as the nerve is exposed. Exposing nerves near the head is how they cause it to turn and "steer".
The books explain it and how the worms move.
they actually Remade the Dune Movies, part two just came out, in part one they go to great lenghts showing and explaining how the worms move.
can reccomend them both!
Entry from Stetmann's Zerg sample research: "I'm learning how some zerg burrow as well. It's extremely sophisticated. They have billions of tiny muscles that vibrate at a low frequency, effectively loosening soil, crumbling rock, and snapping vegetation. They can "swim" through the ground. It's not quite as fast as running, but it's close."
Never thought I'd see a Stetmann quote on a Dune video.
eyyyyyy, my guy Stetmann
Ive seen snakes wriggle and squirm for propulsion in sand (or sand-like particles), while keeping their heads more or less perfectly still
It could also be a way to get nutrients from sifting out, microorganisms in the sand. Maybe they have really complex insides and miles of it. That make it possible to sustain them self off of just sand.
My assumption is that they perform a peristaltic motion at a very high frequency like a piezo electric device. Spice crystals could themselves be that piezo crystal that can convert the sand worm's biothermal/bioelectrical energy into vibratory mechanical motion. By controlling the frequency, amplitude and phase, the sand worm can cause the nearby sand to liquify allowing it to glide through the sand like it is water. If a creature of that size can glide through semi solid earth, it has to be ultra sonics! Also ultra sonic vibrations can breakdown even the metals which is how a lot of abrasive operations work - which explains how the worm can eat and process sand and even the spice mining machinery without breaking sweat. Also ultrasonics can perform density sorting of material which allows the worm to separate nutrition, raw spice and waste sand from its intake.

Sand rocket ship wouldn't be right, because rockets carry all their propellant with them. They'd be sand jet engines.
People forget, the sandworm is an all powerful creature! A lot of it's characteristics aren't fully fleshed in the movies such as the intense heat that eminates from the worms mouth that can cause plasma to propogate in the immediate area. It also creates powerful lightning and electromagnetic fields at will. Because they can generate such energy, which is needed to move their size and account for the square cube law, I postulate that they are able to use the Holtzman effect to manipulate the environment around them and prevent energy loss. I'm sure Frank would like that idea if he didn't think of it already (which i I think he would have)
Kinda imagined they vibrate really hard and make the sand around them like water and then have a tail like an eel and swim through the sand
Rule number one for Physics in Fiction: Real Life Physics do not matter in a fictional setting unless it is specifically told to us that they do.
That rule is why there is sound in space in most sci-fi settings
The sandworms in dune are responsible for the creation of spice. As I remember it involved the ingestion of sand much the same way as when they are drowned in water, they will expel out the blue liquid. That is called the water of life. Another option is that they could have micro movements within their skin, As you see, when Paul holds on 1 side of the worm and it rotates in order to get the sand away from the open area. It's like thousands of coils moving together inch by inch. when you put many of them together in a long line, you get what looks like, the worm not even moving just gliding through the sand.
Blue liquid is the Water of Life -- it's produced when young worms are drown in water, and it's basically Spice essence (Fremen reveal this in "Dune" the book). The Spice spots humans mine on the surface are made when old Worms die, so it's kinda weaker in effect, but still potent enough for humans.
Water is poison to Worms, so if Arrakis gets terraformed -- the Galaxy loses Spice. This is the power Fremen hold -- they have millions of hectoliters of water in their sietches' stashes, all ready to be released on command when and where the Messiah says.
Worm movement is based off of earth worms -- they eat sand and expel it from behind, filtering out nutrients and the little moisture they need. The "expel from behind" part is not what propels the Worms, it's the "eating sand" part that does. They're pulling themselves through the sand.
I’ve always liked the idea that they creat a very high frequency sound that makes the sand behave like a liquid, then they can propel through it like water
Yes, but the question is HOW are they propelling. Everyone in this comment section keeps pointing out that same fact about them turning the sand liquid but that’s not the issue. It doesn’t change the fact that even in water, animals don’t just dart forward like a torpedo.
@@hiimchrisjthe hell are you talking about fish and whales can most certainly dart in straight line just because they’re back fin/tail is moving from side to side doesn’t mean they can’t move in a straight line.
Like I’ve never seen any aquatic animal move from side especially when they’re running from a predator or trying to catch prey
@@sancholoaded2388 yes but the worms don't move their backsides. . .that's the entire point for fucks sake. People need to stop regurgitating the same lines without even understanding the question.
Judging from the rest of the comments, that's actually correct
@@Noobie2k7why couldn’t they? It’s not like we ever see the back of the worm while it’s moving
I thought they would vibrate the sand around them making an almost fluidised bed around them basically making them "swim" through the sand. You can see videos of fluidised beds here on youtube.
I think they can still move like snakes. Snakes heads hold while they move so they can just look ahead and see where they’re going, so the same could apply for the sandworm. They just look straight ahead while the rest of their body is moving.
Seeing him try not to laugh as he explains brings me genuine joy 😂
Why can't we let sci-fi monsters be sci-fi monsters. LoL
the bookes explain it btw. no need for this dumb video, cause its just wrong
It's theorized in the original book that the sand worms are what create the spice in the desert.
