Canonically, the Halo rings didn't rely on rotation to produce gravity. There were artificial gravity generators placed throughout the ring to give the interior of the rings a more natural feeling gravity. The rings were also reinforced by hard light and the materials were artificially created using component elements in a super high gravity forge. Of course this is all science fiction gobbledygook, but the creators of the Halo lore did take these things into consideration. It's nice to see someone take a look at the real science we know now. I wonder, is the 2km size the limit for our current metallurgical knowledge or is this a practical size?
I did a little of the math: At 2 km, it would be a little less than one whole revolution *per minute*, which could cause some of the dizziness. At 1.80 km of diameter, it would be exactly one revolution per minute, which would be cheaper to build and a good way to measure time, but would be a definitely risky endeavor for the health of the people in it. Then again, watching the stars at night inside the ringworld might be a spectacle. One solution I thought about, was that perhaps the roof of the ringworld in that case is covered, and thus wouldn't get natural light, but would instead have a source of light that dims every 24 hours to simulate a day-night cycle.
@@IAsimov one way I imagined a massive space station was in the form of a giant closed cylinder filled with air, the whole thing spins obviously, generation a comfortable gravity on the inner surface, and there is a way smaller inner cylinder inside that act has a structural pillar were other pillars can branch of to the surface, but it would also be covered in LED panels (or some other kind of lighting) to provide a kinda sun like lighting.
@@ledocteur7701 you're basically describing the mormon colony ship Nauvoo from The Expanse, or at least how it is supposed to look finished, they have some nicely grounded sci fi in that show imo
if only it was just one episode... I could live with that at least... I understand the actor wanting a bit of screen recognition for being the guy under the helmet, but they took the piss, he barely has on the helmet at all.
2:00 - That's a great demonstration! As the Halo rings go... Halo ring would be classified as the Bishop Ring which is bigger than O'Neill cylinder, smaller than Niven ring. While the latter may not be possible without active support, Bishop Ring was said to be possible with carbon nanotubes, maybe even in sizes of the Halo. What else needs carbon nanotubes or active support? Advanced launch systems like the orbital ring, space hoop, space fountain or the space elevator. Maybe even Star Tram would need it for parts of it's launch system. So I think Humanity gets to build these one day (or dies out).
IIRC the maximum size limit for a carbon nanotube Bishop ring is on the order of 2000 km for radius (or possibly diameter, can't remember off the top of my head), so still not enough to manage a full Halo ring without active support.

@@Serenity_Dee that’s actually more of a traditional thing, and not an always-must-be rule. many men in america wear their rings on the “wrong” hand or even the wrong finger
Ooh! A few thoughts: Larry Niven's ringworld was arguably an inspiration for the titular ringworlds, though by the size of THOSE things, which in the novel *Ringworld* were as wide as a solar system, and explicitly designed as an alternative to Dyson Spheres, their rotation would be much, much smaller, while having them protected and compressed by the very pull of the sun. The measure of a Halo ring being 10,000 km in diameter is in fact exclusive to Halo 07, and it's a data I just remembered when I was befuddled by the number. Halo rings are usually 30,000 km in diameter, but after Mendicant Bias threw a hissyfit and pre-343 Guilty Spark caveman had to prevent it from crashing against a planet, the ring was forcibly shrunken down from their normal size to the diameter Kyle mentions in the video. REALLY good video! Thanks so much for making this!
As for the Plasma Grenade, It's implied that it Becomes stick after a certain point, because there are animation for the grunts where the grenade doesn't let go of their hands.
“the sticky” part of the plasma grenade is actually just a euphemism for quite literally burning through your armour/skin - and apparently it just melts through shields as well…
@@emilianocastillejos1330 I wanna say no because I'm pretty sure Johnson used some in Contact Harvest, when humanity first encountered the Covenant. They would have had NO time to learn how the grenades worked, much less how to reprogram them to see humans as friends. Also, I've seen LOTS of grunts accidentally sticking their allies.
I'm not really sure how the lore really runs with the plasma grenade, if there is one out there, or if it's just a gaming handwave, but I suspect it's like standard grenades of modern times. After priming the grenade, it starts a charge, what we call "cooking" the grenade if held before throwing, but after the clip that flies off, which I believe is called the "spoon" (iirc, don't quote me on this, lol), disengages the safety, giving that 3-5 second timer before detonation. For a Covenant plasma grenade, when the grenade is primed, there is a short time before the plasma injection initiates, causing that surface reaction, before which, the user would be able to throw the grenade without it "sticking." After the priming trigger, there is a chemical reaction that changes the magnetic state of the grenade, causing it to cling to a wide variety of surfaces, usually armor or vehicles, while landing on the ground can allow it to bounce or burn into the dirt, but not stick (kind of explains why a plasma grenade can bounce or roll around a bit if it doesn't hit a vehicle or enemy). After coming in hard contact with a surface, an additional reactive process occurs, causing a massive chain reaction, and it explodes shortly after. So, not only does the magnetic polarization make it difficult to quickly remove the grenade, but the rapid reaction grants very limited time to toss it away before detonation. As to why we see some grunts having them stick to their hands, it's cause of idiocy or bad reactions and definitely poor discipline. They're not the smartest soldiers around, and they tend to shuffle and bounce around a bit, so say one of them is holding a grenade and bounces it around, then suddenly it gets spooked cause of gunfire, it accidentally hits the priming switch but doesn't realize it, then suddenly, it's glowing in its hand... oh oh, it shakes it around hard, trying to get it off, which triggers the final reaction, then Boom. It doesn't happen to Master Chief or to the Marines because of their discipline and training. When handling a grenade, once you pull the pin, the grenade is "hot" and once the spoon pops, it better not be in your hand. They would feel the same way with plasma grenades. They figure out the priming switch, hear it start to react, then "hot grenade!" and they chuck it immediately. And naturally, they'll test and watch how the grenades work and operate accordingly. Training and discipline. This is all speculation, of course, and I haven't really played through much or watched it all in detail, but maybe this works.
Hey Kyle I’m a blade smith , I’ve been making knives for 7 almost 8 years now. I’m fully aware of the process behind heat treating and tempering a blade. It is a interesting topic that I think would be greatly educational for your viewers. There is a wide range of topics you could cover when it comes to forging anything let alone a blade. From the processes that occur when you get steel hot enough to convert the martensite to austenite . How Damascus / pattern welded steel is made, etc. It would be awesome if you took my suggestion and made a video sincerely your friendly neighborhood blade smith !
That Kazaa reference made me feel old. I remember that all too well. Morpheus too, and of course Napster. It was even more fun over dialup. Could take a few hours to get one song.
Napster, Morpheus, Kazaa... And LimeWire, eMule, and one other I am trying to remember... It's been some years since the last time I used something to download single mp3s. 😂
I remember selecting some 10 songs to download overnight and checking the next day, to find at least 3 that were actually what I wanted, and not songs with the wrong name.. Or even trailers for movies that were actually fan made fake trailers
With a 2km ring revolving at a rate that yields 1g at the rim, the Coriolis force would have an effect on every-day situations (like dropping or throwing things). Especially in a battlefield situation with high speed projectiles moving over long distances -- you'd need to be aware of which direction you're facing relative to the spin and aim accordingly. Aim high when shooting into the rotation, aim low when shooting antirotation, -aim right when 90° CW from the rotation, aim left when 90° CCW from it, and all sorts of combinations of those when shooting in between- (see EDIT notes in my reply comment below for why the strikethrough part was incorrect). And be very careful shooting upward at any significant angle -- you could literally end up shooting yourself in the back as some trajectories will make a projectile loop-the-loop!
Kyle: Halo rings are arguably the most famous superstructures in fiction. The Death Star: Am I a joke to you? Me: Yes. You're absurdly impractical and a waste of money.
Yeah, it would probably cost the Empire the same to base delta zero a planet using a fleet of star destroyers as it would to pay for custodial maintenance of the Death Star for a week.
@@henriquefinger935 anything with advanced technology is science fiction. Sci-fi and fantasy are along the same spectrum, and only "hard sci-fi" is really worth making a distinction over. Like almost every zombie movie is more supernatural horror fantasy than sci-fi, but obviously some have more sci-fi elements than others. The Girl with All the Gifts is the only hard sci-fi zombie flick I can think of, because the "zombies" aren't actually re-animated dead.
I like how the Halo ring in his video is actually rotating. I didn’t notice it on first watch, but when I was rewinding part of it, I noticed the ring is actually spinning slowly. Awesome video
The Orbis type space station from Elite Dangerous is the exact type of habitation ring you are talking about. I would recommend taking a look at one of those as the example of "the scientifically correct halo ring"
I am curious if a ring would be able to hold on to an atmosphere like we see in the game or if it would have to be a sealed environment. Though I guess it's pretty much like water in a bucket being spun around so it's probably fine, just have to make sure it doesn't spill off the sides...that'd be a bad day for everyone.
@@usingthecharlim Well walls are under compression, where as the roof would have to be entirely unsupported (else there are massive pillars all over the place) And the roof would be under massive tension. So it's far easier to build a wall than a roof to a ringworld.
9:00 There’s actually one more boundary limit that’s important. It actually defines the minimum diameter you can make the ring. The radius has to be large enough that your own body height doesn’t significantly change the radius calculation between your feet and head. Too small and there’s more “gravity” at your feet than head. Which causes problems with blood flow and heart problems. It’s why the ISS doesn’t have a spinning section. I did the math years ago and if I recall you’d need the equivalent of like 10 ISS connected end to end and looped in a circle to be big enough.
I learned today that you created your own channel after your departure from "Because Science". It's so nice to see you again, I'm looking forward to watch all of the videos I've missed so far. Thank you (:
I always kinda figured sticky grenades had some sort of fast acting bonding agent that released on impact. Industrial adhesives are no joke and the one I used was a very vibrant blue like the grenades in halo, and it would only need to be effective till detonation.
It's moreso the activation of the plasma grenade vents extremely hot plasma gasses, and when in flight they superheat, and the sticky grenade literally burns itself into the target
@@apprenticeofbeleren you are correct. In the books, marines hit with them are shown; one has it attach to his backpack, or rather melt into it before exploding, and another has one fuse into his shoulder, very painfully, before exploding.
@@smallpeople172 Another Day At The Beach (one of the cut cinematics from Halo 2) shows an ODST having one stuck to his helmet. He survives by yanking the helmet off and throwing it back at the enemy.
@@KillerOrca yes. Same happens in the very first halo novel. Soldier gets it on their pack, throws pack off, but not fast enough - he is still vaporized in the blast
@@smallpeople172 Thats in the Flood Im pretty sure, but close enough. Its when they're hiking up to take Alpha Base and the Covies start raining nades down on them.
They would have to rotate to give a night day cycle. I only just learned the lore says they don't rotate to generate gravity. Both could be true rotate for day night and scifi gravity plating.
...And this is stupid. Why design a scientifically plausible superstructure to then just replace completely correct and realistic solution for gravity with magical technobabble nonsense?
@@DarthBiomech considering the rings can travel through sleepspace, eject parts of it into space and even wipe out entire civilizations, non realistic artificial gravity seems like a necessity.
Halo Rings (if miniaturized) can hold themselves solid without breaking. They could actually exist (subtracting the atmosphere issues and such...) This brings me much joy.
@@grandsome1 Yes, but it gracefully solves two problems at once - the "I wanna to have gravity on my spaceships" and "I want my spaceships to take less than many months to traverse the solar system"
As for plasma grenades sticking, I've done 5 minutes of research on a field I know nothing about and already see research papers on the generation of magnetic fields by the non uniform electron gradient of uneven plasma fields. This tells me that if a plasma grenade is intense enough (it explodes after all) then in theory it sticks to armor, walls and marines gear by magnetising to any metal on that individuals person in the process of the plasma field generation. This would also account for armor lock in reach detaching sticky grenades. The increased repulsion effect of the armors shields overcomes the magnetic attraction of the plasma grenade
@@akale2620 that's why I'm here. To give physics opinions from the perspective of a D grade physics student and put hilarious images of grunts building snowmen into other people's heads
This is a solid game theory xD I love physics based videos, the editing was great! Also ARIA did a fantastic job! Public Speaking is hard enough off camera..doing it on camera, even harder.
Now, I don’t think this is established in the lore, but I thought of a way something the size and maybe mass of a halo could stay together despite the force. A few years ago I had the random thought that those tiny circles on the outside on the ring could be thrusters/engines. If you notice, in all the games, the halos’ outside have these tiny circles placed in regular patterns. If the halo could provide thrust (fusion engines?), it would produce an additional centripetal force. It could produce a huge magnetic field and collect solar wind or the upper atmosphere of the planet it orbits via Bussard collectors to use as fuel for the engines. No gravity plates or unobtainium necessary.
Interesting ARIA hologram... Not quite what I was expecting but it really fits the theming on the channel and the themes of the episode. She really does look like Cortana. Also great video 💚

And what about the Halo Array's primary function as a weapon? I know the original design was inspired by a version of the Dyson Sphere involving just building a ring around a star but that obviously isn't at all related to how the exist now in lore so an episode on any potential science allowing these things to be weapons would be interesting.
I'd love that, especially since it only destroys the nervous system, could it be some kind of gas being sent through slipspace or via neural physics? And what about the bodies of the life that was destroyed the effects on the environment would be horrific; luckily the forerunners thought of that, but I'd love to know what the consequences would be
unfortunately, the lore behind how the weapon functionality of a halo within the halo fiction is based entirely on *very* fictional science. i suppose there could be something to make a video about there, but keeping everything within the bounds of real science would make for a depressingly ineffective weapons array, at least when held in comparison
The most explicit canon explanation for the mechanism behind what they fire and how they exterminate life is given in the novel Halo: Cryptum, where by "radiating a powerful burst of cross-phased supermassive neutrinos," the rings "were capable of destroying all life in an entire star system. Properly tuned and powered...they could kill all neurologically complex life across whole swaths of the galaxy." In the Halo Encyclopedia (the 2011 edition), the burst is also described as "a harmonic frequency, targeting certain cells in the nervous systems of any significant sentient organism." So basically, space magic :)
@@rustyshackleford9888 Part of what makes it possible is in the Halo Universe, all life is the product of the Precursor. There are certain universal characteristics of sentient life because they all have the same architect. Basically,a Halo can brute force kill anything within "25,000 lightyears" (at least instillation 04 according to 343 guilty spark). With the Index, which has a catalog of sentient life and those harmonic frequencies, and the entire Halo array acting together, all life created by the precursor, which is all life in the Milky Way, will be dead. "This galaxy will be quite devoid of life, or at least any life with sufficient biomass to sustain the Flood." At least that's my understanding of it.
This would have been an awesome chance to collaborate with Instillation00 (esteemed Halo Engineering nerd) and or Isaac Arthur (Has a whole series on Mega Structures) Awesome episode as always though, would love more Halo stuff in the future (maybe your take on the armor, or the augmentations)
I never thought about it but Halo probably did contribute to my interest in space and hence lead to me learning of dyson spheres and ring worlds and other mega structures. Not to shill but I know a strategy game where you govern a species and later it will let you build those kind of mega structures. It’s slow as hell but I recommend it. (Stellaris)
Forerunners were also meant to have the tech to just make full on planet sized gravity forcefields and stuff. Maethrillian didn't use rotation to simulate gravity, and neither did the Ark. Even humanity had "gravity plating" of some kind in its space ships by the 26th century in this setting.
Another person who is showing their age, I made the connection to Niven's "Ringworld", and his need to create Skrith, the material with enough tensile strength to hold a solar system sized ring together. Question about the viability of the 2 Km ring, what would the gravitational gradient be for an average height human standing on the ring interior. If the force of gravity at your head is different enough from the force at your feet, that can cause discomfort.
I KNEW RINGWORLD WAS A THING!! Every kept saying "You mean Discworld?" (Which I did...) but everyone was like "Ringworld isn't a thing." Glad to see I am not completely crazy. (There are parts missing:p)
Excellent video! Also, I personally like to imagine that Halo plasma grenades stick because they are covered in some sort of shock-activated adhesive compound and that they (unrelatedly) glow because the reaction (or charging process, or whatever) that generates the explosion emits so much light that it shines through the container.
if ISS stops at place suddenly (1sec long deceleration), then the astronauts would feel about 8000000% of their weight at the moment of their contact with the wall
Hey @Kyle Hill, returning Super Nerd here. love the show, the episode, and the video game series, so I have some thoughts on the Plasma Grenade. I've always thought the plasma grenades use the electromagnetic properties of plasma to magnetically bond to the target until they explode. They aren't always glowing, and have to be activated first. Once thrown I have always assumed it's about the impact that activates a magnetic effect which clings to metals found in the target. This makes sense because they can cling to metal armor and vehicles alike. This does not make sense when they cling to the bodies of the Brutes (a nickname of one alien race), who sometimes forego armor entirely in favor of their hairy and thick near bullet proof hides, or the Guta, another alien species of giant gorilla like animals found on the planet Reach. It's possible that these aliens have a high metal content in their bodies, possibly their bones, especially since Brutes invented electricity throwing weapons when they were at war with one another before joining the enemy faction the Covenant. Maybe they are susceptible to electricity due to some ferrous properties of their bodies, so that's what they used on each other. However, it seems odd that they and the Guta alike both possess ferrous properties while being the only fleshy targets we ever throw plasma grenades at. That's a major coincidence The truly strange thing is really what the plasma grenades do and do not "stick" to. They will stick to a person, but not a wall. They will stick to a vehicle, but not a crate. Clearly the "stickiness" property is controlled, and the grenade has some kind of suite of sensors and computational ability to determine what it has struck on impact, and will only then stick to the object if it "wants" to. Otherwise it's unlikely that such a system could be so particular about what it sticks to. For example, it may produce a complex magnetic field that acts as a sort of 3d scanner, like an MRI by making use of the magnetic properties of the plasma contained within the grenade which is later used to create the detonation. But regardless of how it determines what to stick to, it must possess some kind of radical method of sticking because it deals no damage to the target until it explodes. This is the main reason I am disputing your idea, Kyle, that it's melting the target or itself to create a form of adhesion. It must be some kind of mechanism that's relatively harmless given the circumstances and lack of damage until detonation. I suggested magnetism despite the few inconsistencies in ferrous materials, but it could also be something chemical like a snail's fluid due to how they're manufactured. See, the plasma grenades are manufactured by yet another alien race in the conglomerate known as the Covenant. These are nicknamed the Engineers, and they possess tentacle appendages that can warp their shape to form many tool like structures and create small artificial gravity fields. They also hold many materials separately inside themselves in bladders for construction, and have minds that can reverse engineer new technology in minutes. They do all of this because they were not evolved, but rather created by an extinct ancient alien species. They're actually biological robot construction workers and inventors, hence their nickname. Anyway, since the plasma grenades are manufactured by these biological creatures, they may possess some kind of biological solution to this problem in the form of a sticky solution of chemicals which the grenade secretes just before impact. This is also interesting with the MRI scanner idea because the Engineers are 100% peaceful since their minds were programmed not evolved, and they're enslaved by the Covenant. They always make tools of peace, but those are then warped by their commanders on pain of death into tools of destruction. If the plasma grenades started out as portable MRI machines for medical purposes, or maybe a means for the blind to see in magnetic resonance, then they might have presented it to their enslavers only to be ordered to make the plasma core overload and explode on impact. The stickiness might have originally been meant to stick the device to a wounded individual or damaged vehicle for diagnostics, hence why it only seems to activate on impact with those things. The plasma core might have been both a power source and a means to produce the MRI effect of the device. All of this makes sense within the confines of the Halo universe, and it bridges the gap substantially between the fiction and reality if it were to be made canon for the series.
If I'm not wrong the explanation is that when activated they start to leak their inner coolant which is why we see gas coming out, and eventually this coolant not only vents but covers the surface of the grenade making it sticky, without coolant inside then the core of the grenade collapses and creates the reaction we see as an explosion, this however doesn't really explain why it doesn't sticks to terrain but it does on small vehicles and infantry, I mean, that's probably because gameplay but, it's a quite interesting characteristic of the plasma grenade
Issac Arthur does this one too, and if you stack up a bunch of the 2km rings you get an O’Neill cylinder (2 L’s!). That’s what I want to build, after the other ring structure!
Both the questions Kyle asks in this video have answers in the lore, I think Spartans have a system in their suit to handle puke in the event they throw up, and the plasma grenade's core heats up the paint on the outer layer causing it to become sticky
As one who played and loved the original Halo when it came out, and someone who burned mp3's onto CDR's (from Kazaa, mind you) and may or may not have shattered a disc or two..... that hurt Kyle.
Main problem is the interiors of the Expanses ships are way too big for what the measurements apparently are. Otherwise they are very practical and realistic given the Epstein drive yes.
Great video! Cononically halo rings actually do use artificial gravity generators and only use the spinning as a backup way, but.... few people actually know that and isn't that important if a detail.
The Forerunners made a big deal about certain technological feats that had to be achieved in order for a civilization to attain "rank" one being able to condense matter, demonstrated by Spartan Mjolnir armor (the MC's armor weighs around 1000lbs), another was being able to subvert the laws of physics to build megastructures. This was something Humanity had yet to accomplish. That said, the Forerunners had, through some variation of Active Support, a means of using active vectors of force, energy beams, streams of particles, to hold stuff up. This version being able to hold matter together under even the most insane forces. Think Star Trek's "Structural Integrity Fields" that allow actually structurally unsound vessels (as most Starfleet vessels are) to survive the stresses and strains of just maneuvering with any degree of interest to being shot clean through and not collapse [or] shatter. In this way, the HALO rings are 5000km radius and not fling themselves apart. It also helps that they are not spinning very quickly at all, relatively speaking.
@@dr.catherineelizabethhalse1820 They have to in order to generate artificial gravity. much more believable and sustainable than powering gravity panels.
@@slimerewoods5766 It's easier to spin also, actually watch the cutscene s in the actual game, Original version or Blurr's remaster, the Halo rings spin... albeit Slowly.
@@slimerewoods5766 The ring, because of its orientation to the planet it orbits, gets its day-night cycle orbiting the planet , passing through its shadow. Otherwise, to accomplish a day nioght cycle, the ring would have be spin 'like a coin on it edge. This would destroy the ring becasue it would begin the stretch toward the perpendicular of the axis of rotation. Aggravated by having MORE MASS being directed, actually and/or by inertia, the ring could not hold. The ring would NOT have its of biosphere. To resist such forces, would require more energy than it is worth. Your notion does not work based on what is shown in HALO and what is known in real life of physics. The Ring spins along its circumference to generate gravity. It is easier, safer, harder to subvert, and reserves energy for the rings main function as a galactic scale WMD. Why expend the power for something you don't need power for, if you don't have to? Whatever Clarktech solution the Foreruuners used is immaterial since were were talking about Artificial Gravity and NOT how they keep the lights on. And I started this thread on how they ring would stay together as it spun. Again Clarktech but that made the most sense for what is shown in HALO and in Rel live is known of physics. Clarktech? Please refer to Arthur C Clark's Third rule "Any technology sufficiently advanced is indistinguishable from Magic. (Paraphrase)"
Great video! A good follow-up video would be the Halo weapon array itself. It uses a tuned pulse of supermassive neutrinos to wipe out all intelligent/complex lifeforms.
The guy has made videos on the science behind _Super Saiyans,_ “BS game science” would not stop him. If he can talk about the theoretical science that would be needed to make anime stuff real, he could breakdown what it would take to make the weaponry of Halo real.
In 'Consider Phlebus' by Iain M Banks a character meets their demise due to a nice little quirk of Ring Structures... basically, he turns on his Anti-Gravity suit, jumps off a ledge and plummets to his death. Who knew gravity and rotation could be so similar yet so different? Also, I highly recommend Iain M Banks to each and every one of you. Peace
I do like his books. Very much enjoyed The Player of Games and Feersum Endjinn. However have you noticed that there's always a strangely enigmatic character (occasionally Scottish) in his books that's far better than everyone else at whatever they do? I wonder who that could be? :D
@@Shanghaimartin Hmm... I never picked up on that particular detail but now that I think about it... Personally, I always thought the Minds reflected Banks' point of view... definitely intelligent, somewhat irreverent and served with a side of sarcasm and feigned innocence/ignorance. I usually find myself re-reading Use of Weapons, Consider Phlebus, Surface Detail or Excession.
I think I remember this bit - wasn't it when they were running along the ship before the tidal wave hit? He didn't want to find the stairs, so he just jumps off the deck to float to the one below?
KaZaa! Holy crap, I haven't heard that name in quite a while. The rate at which our recent past becomes stranger in retrospect is kind of alarming, sometimes.
*Captain America voice* I got that reference Also, for the Plasma Grenades sticking, I always figured it was because, while emitting the light and energy aura, it wasn't "active" until you clicked and threw it. Upon clicking it, it'd activate its internal components and, after a second, become "sticky", either through a chemical reaction or electro-magnetic coating, allowing you to have time to throw it but also allowing it's other effects to work within canon
For the plasma grenade question at the end, is there an adhesive that could retain its ability to stick at such hot temperatures? To activate the grenade ingame you first press a button on it, perhaps when pressed it starts secreting an adhesive on the surface of the sphere? Picturing something like how a poison dart frog secretes the poison from its skin when threatened. It takes the grenade a number of seconds to explode anyway so it doesn't instantly turn into a ball of plasma right away, so it could possibly work. Adhesive gets secreted onto the surface of the grenade, internal temperature of said grenade heats up while getting ready to explode, the adhesive helps the grenade attach onto a target, then gets melted away along with whatever it was attached to upon detonation
I believe the in-universe explanation for how the plasma grenades stick is that, once thrown, the grenade heats up so much that it melts into things to stick to them. I could be mistaken, as it's been a while since I read the books. But I'm fairly sure that's how they work :)
@@damienstitchman1981 I remember seeing that in the books as well Only thing I have against that explanation though is energy shields Your shields ingame don't go down when a grenade sticks to you, so the grenade with this explanation would have to melt an energy shield(Although if we look at a Jackals energy shield, a plasma grenade bounces off of them)...did we just find a plot hole in Halo?
@@NecronNate You know, I'm not quite sure what the explanation there would be. Every time I think of something it comes back to the shields not going down. We might have discovered a plot hole here!
And so Aritana went insane, blew up the Brute homeworld and held the entire UNSC hostage under threat of massive EMPs, all because Kyle couldn't help fanboying it up. Kyle the plasma grenade could have an adhesive strip on it. >.> just pull it off when you throw it, or maybe push a button and it becomes covered in adhesive except for a specific section you hold it by? what I really want to know are how the needlers are able to home in on targets when their ammo is basically crystal, same with the needler supercombines, how do those work? could they work?
I don't know how many people know the lore behind them but they were all designed to be put in like an array and they actually got used to wipe out all sentient life in the galaxy at one point in the halos universe so the forerunner secured their own shield worlds " " to hide from the blast and the humans inhaler are supposedly descendants from the forerunners
Might have been worth noting that a 5000 km ring would not need a "roof" to contain atmosphere. A 2km ring would either need to be roofed, or to actually be a hollow disc.
With Earth's gravity you would just need a ~150km lip around the edges to keep air in. Nothing between you and vacuum but air. Think about how thick Earth's atmosphere is and it'll make sense. Have some very tall 'mountains' around either side of the ring.
I've been wanting this video for the longest time, most people say yes, but I've been thinking "doesn't gravity and the spherical shape of earth stops the sun radiation from tearing the molecules that made the atmosphere from being easily torn? Wouldn't that be way too easy if it's just a ring around a sun?" Edit 1: Apparently what keeps the earth protected is the magnetosphere that exists thanks to the core of the earth. I think it gives it away, can't hardly have a "magnetosphere" without a sphere, but beyond that, making a system of cable rigging around the Halo to make it have a magnetic ring to protect the atmosphere would be a resource nightmare. It's already the opposite nightmare the idea that we would need to do that to give Mars a magnetosphere to let it have atmosphere and make it liveable.
The core is what provides a magnetic field for earth and that’s what protects the atmosphere from being torn apart…and no you wouldn’t be able to wrap the halo around the sun, it would have to be far out and tilted so it can receive sunlight at different times like the graphic showed.
afaik nope, magnetosphere yes, round shape no, the ring is something we could in theory build, as in 'how' is basically understood (Active support is absolutely necessary, think a hose pipe going rigid as the water flows, that is active support at it's simplest.) Isaac Arthur explains how in his megastructures series.
@@justicar5 But doesn't the name "magnetosphere" give it away? It's hard to have a magnetosphere without a "sphere", without a center providing magnetic protection from the sun radiation to keep the molecules in the air from ripping away.
it's not the shape of earth preventing the solar wind from tearing apart the atmosphere, but earths magnetic field, driven by earths molten core. Thats the reason mars doesn't have an atmosphere, but earth and venus do. No molten core, no magnetic field, no atmosphere. I imagine it would take immense effort and huge amounts of energy to generate a magnetic field big enough to protect the atmosphere on a spinning ring in space, not to mention that the spinning itself would probably catapult the atmosphere away, since it can simply flow around the ring into space. A glass dome on the inside of the ring would likely be way easier and more practical (and much easier to explain than an imaginary device generating a magnatic field)

Excellent video as usual Decaf Thor- I mean Kyle! I wish more people knew about Ringworld, what the Halo rings are based on. The novels by Larry Niven describe a ring that, instead of orbiting a gas giant, replaced an entire star system. I grew up with Halo, and it will always have a special place in my heart, but Ringworld was Halo in 1970. And a hell of a lot bigger. Using the equations in the video, I learned that Ringworld spins at 0.000774 RPM. Someone please correct me if my math is off, I tried to do it on my phone lol
Great video Kyle, always an entertaining and informative adventure. I'm wondering if you could possibly go into the science of such a ring orbiting the earth and how it would effect people/Spartans on each side of the rings acceleration. Would the motion of the ring orbiting cause acceleration/deceleration of objects on the advancing side of the spinning ring compared to the side spinning the opposite way of the orbits travel?
Have you tried "children of a dead earth"? It's a bit _too_ realistic for my taste though (as in: extremely pedantic), and suffers from a case of "programmer art" syndrome. Other than that there's only Kerbal Space Program, I think.

Hi Kyle! I was wondering if you could make a video on how the hangar shields work in Halo, Star Wars, and other sci fi videos/shows/games. They trap air, but let more dense objects through. Is this possible by any means with our current technology? If not, is it something that is theoretically possible in the future?
Not sure about shields, but a barrier of something like self-sealing, highly elastic but prone to puncture material *could* work. Trapping the air inside, letting ship pass with some force, then sealing back and retaining most of the air inside. Although, anyway, it would *not* be transparent. And would probably feature somewhat limited number of uses until a replacement would be needed
2 km Halo ring... And what would You call a mutliple 2 km Halo ring set side by side? Well, an O'Neill Cylinder :D And the living space that You would loose due to shrinkage of the ring's radius, You would recalim it by making the ring wider. So wide in fact, it should be considered a cylinder, not a ring ;) Halo ring has a little under 1×10^7 km^2 of surface (one side). To get that kind of surface on 2 km diameter of cylinder, it would have to have almost 1.600.000 km of length. It would be a hell of a straw XD But, if we shrink the ring proportionally, the width would be 63.6 m XD That would be pointless. The surface would be around 0.4 km^2 (under 100 acres). No, that just won't do. Lets get 1 km radius ring but with width of 10 km (a tube 5 times longer than wide). I think that's reasonable. That would give us 31.42 km^2 (7764 acres). Not much, still, but way better. My point is this - rings are good if they are (very) big. If scale is small, you're better off with an O'Niell cylinder ;)
At 5:58 and I'm already thinking about the water bucket experiment. You tie a length of rope to the bucket handle and fill the bucket with water. You then start spinning the bucket by the rope and the water stays inside because it's feeling force in 2 directions: an "outward" pushing force and a "forward" pushing force.
Remember: when talking to your super-intelligent AI partner/girlfriend/wife, NEVER call them by another AI's name. Jealousy and over-thinking is not a good thing for someone who can think many times faster than you.
Halo rings generate artificial gravity through generator facilities in the ring, not rotation. In fact, I believe they are more like ring-like starships, as they can travel, including at FTL speeds. However, they do not rotate.
an alternative to a 2km ring would be a 2km tether between two equal mass modules or shorter with a heavier counterweight at one end (and longer for a lighter counterweight) so long as it's not intended for habitation. you could have this perpendicular to the thrust axis but a better idea might be parallels to the thrust axis. this means no need to change the orientation of the living spaces between thrust gravity when accelerating, and spin gravity when coasting. just lay out your ship like a skyscraper, with the thrusters at the base and a tether + counterweight system at the top.
Random conjecture; Maybe the plasma grenades either have a built in electromagnet that activates when it impacts something metal like master chief's armor or a warthog? OR Perhaps the plasma is generated by intense electromagnetic induction and the field makes it stick? That or maybe they just modeled them on sticky grenades from WW2
If you want an open top atmosphere instead of a tube world you'd need walls on the side of the ring that are high enough that the pressure of the atmosphere would be livable. And since the artificial gravity tapers off quicker than real gravity as you go "up" that means thicker than Earth's atmosphere. So that 2 km Halo would have to be a tube or a completely sealed disc 🤔
They use artificial gravity generators throughout the halo ring to generate gravity, not rotation… and the walls on a halo ring are something like 200km in canon
@@smallpeople172 Yeah but since this could theoretically be created and anti gravity probably isn't in the cards for us, that's something we would have to do to keep the air in.
Building a ring as a kind of habitat or spaceport (or whatever other function) only makes sense as step one. Once you get your ring, you'd expand outwards from the edges of the ring and start making a cylinder for more surface area. Making a gigantic ring with a huge diameter looks cool, but from an engineering perspective doesn't make sense because you're going to need rarer and more expensive materials the wider and wider it gets. Making the cylinder longer wouldn't require any different materials and would be logistically easier as you wouldn't have to disconnect the ring and add material (and somehow keep it from flying apart), and stitch it back together again; or stop the rotation (which means everything would have to be strapped down) Also, you wouldn't build a single ring but probably several "rings inside rings". The reason you would do this is the closer to the center you get, the less the apparent gravity. So, your inner-most ring would have very little gravity and would be useful for literally heavy manufacturing, bio-tech, and probably a host of tons of fields of research. tl;dr -- build a cylinder, which is really just a "thick" ring. It's got more surface area and can easily be expanded outwards. Also, build rings inside of rings so that you can have lower and higher gravity areas for various different functions like low-grav manufacturing.
Welll. Harmonics has a word to say here too. You really need two cylinders linked together, and that can impose practical limits on the diameter, and the issue of the bearings joining the two wearing out and something like this you want to build for the next few hundred thousand years, and there is the issue of lighting. Again. Really long lifespans for an artifical planet so your better off just using a really long lasting source, a star. And then. You still end up going for much smaller diameters because you do not want any active support schemes that could break down. There's a lot of reasons the O'Neil cylinder was space island 3. It might not ever be practical, but one and two definitely should be.
13:38 The plasma grenade would make more sense if it only stuck to armor like Kyle said. The plasma might sit on top of the energy shields. Allowing someone to throw it as long as their shields are up, but if you try to grab the grenade with your shields down, it will stick to the users own hand, and it won't stick to a target if the target has energy shields up.
IIRC, the main issue that comes with Halo rings creating artificial gravity by spinning is that trying to land on the ring would be difficult since you risk crashing or burning up in atmosphere if you don't match the ring's rotation on approach
Could be solved if you're willing to trade a ring for a wheel. Spokes connecting to a rotating docking collar in the center means you'd only need to park next to it and match its rotation like in Interstellar.
Not that difficult, I think. Approach the surface from the edge, match the rotational velocity and then hoop over the edge to the landing site. But you would be able to land on them only in the vector along their direction of rotation, and you'd need to compensate for the ring trying to constantly escape "up" from your POV.
The type 1 anti personnel grenade aka The plasma grenade has the plasma contained within the casing, there is a primer button on the case of the grenade, the casings magnetic function activates on a timer after the primer is pressed, the grenades explosion is not on a timer but is triggered shortly after the grenade is accelerated and then comes to rest! You can throw plasma grenade to any distance and they will not explode until they stop moving.
The Ringworld Books got this treatment between the first and Second book. The Foreword for Ringworld Engineers Begins with Larry Niven Telling the reader that he received so much fan mail from people of several scientific and mechanical specialties, who really enjoyed ringworld...but had to explain to him why it couldn't work.
In the original book, the "scrith" is distinctly not normal matter. It is represented as a form of degenerate matter held together by strong nuclear force. Like neutronium but blocking 40% of neutrinos.
Ktle, I think the plasma grenade works like a normal frag, but it has a fuse time that starts the Casing as a metal that will stick as it melts. John pushes the primer, the core begins to warm up, in air the casing splits to regulate temperature so that the casing can attach by the melting polymer it was, then the pressure from the plasma is too much and explodes the molten metal at high speed. The casing probably has time from priming to detention that it is still safe to throw. In some of the Halo games(if not all of them) you can throw the plasma grenade up and have it land and stick on you.

Claire Max is the Pinnacle of the female form.
Canonically, the Halo rings didn't rely on rotation to produce gravity. There were artificial gravity generators placed throughout the ring to give the interior of the rings a more natural feeling gravity. The rings were also reinforced by hard light and the materials were artificially created using component elements in a super high gravity forge. Of course this is all science fiction gobbledygook, but the creators of the Halo lore did take these things into consideration. It's nice to see someone take a look at the real science we know now. I wonder, is the 2km size the limit for our current metallurgical knowledge or is this a practical size?
I think if it were any smaller than 2km it would need to spin at more than 3 rpm, causing the sickening effect NASA observed.
@@silverywingsagain I think they was asking about bigger rings, but either way, it probably wouldn't end too well
I did a little of the math: At 2 km, it would be a little less than one whole revolution *per minute*, which could cause some of the dizziness. At 1.80 km of diameter, it would be exactly one revolution per minute, which would be cheaper to build and a good way to measure time, but would be a definitely risky endeavor for the health of the people in it. Then again, watching the stars at night inside the ringworld might be a spectacle.
One solution I thought about, was that perhaps the roof of the ringworld in that case is covered, and thus wouldn't get natural light, but would instead have a source of light that dims every 24 hours to simulate a day-night cycle.
@@IAsimov one way I imagined a massive space station was in the form of a giant closed cylinder filled with air, the whole thing spins obviously, generation a comfortable gravity on the inner surface, and there is a way smaller inner cylinder inside that act has a structural pillar were other pillars can branch of to the surface, but it would also be covered in LED panels (or some other kind of lighting) to provide a kinda sun like lighting.

2:00 - That's a great demonstration!
As the Halo rings go... Halo ring would be classified as the Bishop Ring which is bigger than O'Neill cylinder, smaller than Niven ring. While the latter may not be possible without active support, Bishop Ring was said to be possible with carbon nanotubes, maybe even in sizes of the Halo. What else needs carbon nanotubes or active support? Advanced launch systems like the orbital ring, space hoop, space fountain or the space elevator. Maybe even Star Tram would need it for parts of it's launch system. So I think Humanity gets to build these one day (or dies out).
IIRC the maximum size limit for a carbon nanotube Bishop ring is on the order of 2000 km for radius (or possibly diameter, can't remember off the top of my head), so still not enough to manage a full Halo ring without active support.

Ooh! A few thoughts: Larry Niven's ringworld was arguably an inspiration for the titular ringworlds, though by the size of THOSE things, which in the novel *Ringworld* were as wide as a solar system, and explicitly designed as an alternative to Dyson Spheres, their rotation would be much, much smaller, while having them protected and compressed by the very pull of the sun.
The measure of a Halo ring being 10,000 km in diameter is in fact exclusive to Halo 07, and it's a data I just remembered when I was befuddled by the number. Halo rings are usually 30,000 km in diameter, but after Mendicant Bias threw a hissyfit and pre-343 Guilty Spark caveman had to prevent it from crashing against a planet, the ring was forcibly shrunken down from their normal size to the diameter Kyle mentions in the video.

As for the Plasma Grenade, It's implied that it Becomes stick after a certain point, because there are animation for the grunts where the grenade doesn't let go of their hands.
“the sticky” part of the plasma grenade is actually just a euphemism for quite literally burning through your armour/skin - and apparently it just melts through shields as well…
Isn't there something in the lore that says it's programmed matter or something that detects if the creature holding the grenade is a friend or foe?
@@emilianocastillejos1330 i think there is? i’m gonna have to look that up at Halopedia…
@@emilianocastillejos1330 I wanna say no because I'm pretty sure Johnson used some in Contact Harvest, when humanity first encountered the Covenant. They would have had NO time to learn how the grenades worked, much less how to reprogram them to see humans as friends.
Also, I've seen LOTS of grunts accidentally sticking their allies.
I'm not really sure how the lore really runs with the plasma grenade, if there is one out there, or if it's just a gaming handwave, but I suspect it's like standard grenades of modern times. After priming the grenade, it starts a charge, what we call "cooking" the grenade if held before throwing, but after the clip that flies off, which I believe is called the "spoon" (iirc, don't quote me on this, lol), disengages the safety, giving that 3-5 second timer before detonation.
For a Covenant plasma grenade, when the grenade is primed, there is a short time before the plasma injection initiates, causing that surface reaction, before which, the user would be able to throw the grenade without it "sticking." After the priming trigger, there is a chemical reaction that changes the magnetic state of the grenade, causing it to cling to a wide variety of surfaces, usually armor or vehicles, while landing on the ground can allow it to bounce or burn into the dirt, but not stick (kind of explains why a plasma grenade can bounce or roll around a bit if it doesn't hit a vehicle or enemy). After coming in hard contact with a surface, an additional reactive process occurs, causing a massive chain reaction, and it explodes shortly after. So, not only does the magnetic polarization make it difficult to quickly remove the grenade, but the rapid reaction grants very limited time to toss it away before detonation.
As to why we see some grunts having them stick to their hands, it's cause of idiocy or bad reactions and definitely poor discipline. They're not the smartest soldiers around, and they tend to shuffle and bounce around a bit, so say one of them is holding a grenade and bounces it around, then suddenly it gets spooked cause of gunfire, it accidentally hits the priming switch but doesn't realize it, then suddenly, it's glowing in its hand... oh oh, it shakes it around hard, trying to get it off, which triggers the final reaction, then Boom. It doesn't happen to Master Chief or to the Marines because of their discipline and training. When handling a grenade, once you pull the pin, the grenade is "hot" and once the spoon pops, it better not be in your hand. They would feel the same way with plasma grenades. They figure out the priming switch, hear it start to react, then "hot grenade!" and they chuck it immediately. And naturally, they'll test and watch how the grenades work and operate accordingly. Training and discipline.
This is all speculation, of course, and I haven't really played through much or watched it all in detail, but maybe this works.

With a 2km ring revolving at a rate that yields 1g at the rim, the Coriolis force would have an effect on every-day situations (like dropping or throwing things).
Especially in a battlefield situation with high speed projectiles moving over long distances -- you'd need to be aware of which direction you're facing relative to the spin and aim accordingly. Aim high when shooting into the rotation, aim low when shooting antirotation, -aim right when 90° CW from the rotation, aim left when 90° CCW from it, and all sorts of combinations of those when shooting in between- (see EDIT notes in my reply comment below for why the strikethrough part was incorrect). And be very careful shooting upward at any significant angle -- you could literally end up shooting yourself in the back as some trajectories will make a projectile loop-the-loop!

The Orbis type space station from Elite Dangerous is the exact type of habitation ring you are talking about. I would recommend taking a look at one of those as the example of "the scientifically correct halo ring"
I am curious if a ring would be able to hold on to an atmosphere like we see in the game or if it would have to be a sealed environment. Though I guess it's pretty much like water in a bucket being spun around so it's probably fine, just have to make sure it doesn't spill off the sides...that'd be a bad day for everyone.
It would if you create a wall at the sides of the ring
The halo games acknowledge this, there are massive walls on the sides preventing the atmosphere from spilling over.
You'd have to have walls the height of the atmosphere. You may as well just build a roof, it would be more effective.
@@usingthecharlim Well walls are under compression, where as the roof would have to be entirely unsupported (else there are massive pillars all over the place) And the roof would be under massive tension. So it's far easier to build a wall than a roof to a ringworld.
@@usingthecharlim Less aesthetic though, would rather see space and the grand arching ring than a ceiling.
9:00 There’s actually one more boundary limit that’s important. It actually defines the minimum diameter you can make the ring.
The radius has to be large enough that your own body height doesn’t significantly change the radius calculation between your feet and head.
Too small and there’s more “gravity” at your feet than head. Which causes problems with blood flow and heart problems.
It’s why the ISS doesn’t have a spinning section. I did the math years ago and if I recall you’d need the equivalent of like 10 ISS connected end to end and looped in a circle to be big enough.

As for plasma grenades sticking, I've done 5 minutes of research on a field I know nothing about and already see research papers on the generation of magnetic fields by the non uniform electron gradient of uneven plasma fields. This tells me that if a plasma grenade is intense enough (it explodes after all) then in theory it sticks to armor, walls and marines gear by magnetising to any metal on that individuals person in the process of the plasma field generation. This would also account for armor lock in reach detaching sticky grenades. The increased repulsion effect of the armors shields overcomes the magnetic attraction of the plasma grenade

Kyle: Halo rings are the most famous mega structures in science fiction.
The deathstar: AM I A JOKE YO YOU
Yes it is. Do you know how insane the 7 halo are
The Jenolan Dyson Sphere: Amateurs.
Didn’t all of those blow up a long time ago in a galaxy somewhere.
Yeah but the 7 halo rings can kill everything in the galaxy at once
Deathstar- blows up one planet
1 halo ring- kills all life in the galaxy.
This is a solid game theory xD I love physics based videos, the editing was great!
Also ARIA did a fantastic job! Public Speaking is hard enough off camera..doing it on camera, even harder.
Now, I don’t think this is established in the lore, but I thought of a way something the size and maybe mass of a halo could stay together despite the force. A few years ago I had the random thought that those tiny circles on the outside on the ring could be thrusters/engines. If you notice, in all the games, the halos’ outside have these tiny circles placed in regular patterns. If the halo could provide thrust (fusion engines?), it would produce an additional centripetal force. It could produce a huge magnetic field and collect solar wind or the upper atmosphere of the planet it orbits via Bussard collectors to use as fuel for the engines. No gravity plates or unobtainium necessary.
Interesting ARIA hologram... Not quite what I was expecting but it really fits the theming on the channel and the themes of the episode. She really does look like Cortana.
Also great video 💚

I hope he doesn’t want us to report him…
And what about the Halo Array's primary function as a weapon? I know the original design was inspired by a version of the Dyson Sphere involving just building a ring around a star but that obviously isn't at all related to how the exist now in lore so an episode on any potential science allowing these things to be weapons would be interesting.
He doesn't do these things anymore... Or the Law Enforcement will visit him to figure out if he is a Villain with a hidden layer or not.
I'd love that, especially since it only destroys the nervous system, could it be some kind of gas being sent through slipspace or via neural physics? And what about the bodies of the life that was destroyed the effects on the environment would be horrific; luckily the forerunners thought of that, but I'd love to know what the consequences would be
unfortunately, the lore behind how the weapon functionality of a halo within the halo fiction is based entirely on *very* fictional science. i suppose there could be something to make a video about there, but keeping everything within the bounds of real science would make for a depressingly ineffective weapons array, at least when held in comparison
The most explicit canon explanation for the mechanism behind what they fire and how they exterminate life is given in the novel Halo: Cryptum, where by "radiating a powerful burst of cross-phased supermassive neutrinos," the rings "were capable of destroying all life in an entire star system. Properly tuned and powered...they could kill all neurologically complex life across whole swaths of the galaxy." In the Halo Encyclopedia (the 2011 edition), the burst is also described as "a harmonic frequency, targeting certain cells in the nervous systems of any significant sentient organism." So basically, space magic :)
@@rustyshackleford9888 Part of what makes it possible is in the Halo Universe, all life is the product of the Precursor. There are certain universal characteristics of sentient life because they all have the same architect. Basically,a Halo can brute force kill anything within "25,000 lightyears" (at least instillation 04 according to 343 guilty spark). With the Index, which has a catalog of sentient life and those harmonic frequencies, and the entire Halo array acting together, all life created by the precursor, which is all life in the Milky Way, will be dead. "This galaxy will be quite devoid of life, or at least any life with sufficient biomass to sustain the Flood." At least that's my understanding of it.
This would have been an awesome chance to collaborate with Instillation00 (esteemed Halo Engineering nerd) and or Isaac Arthur (Has a whole series on Mega Structures)
Awesome episode as always though, would love more Halo stuff in the future (maybe your take on the armor, or the augmentations)
Agreed
I never thought about it but Halo probably did contribute to my interest in space and hence lead to me learning of dyson spheres and ring worlds and other mega structures.
Not to shill but I know a strategy game where you govern a species and later it will let you build those kind of mega structures. It’s slow as hell but I recommend it. (Stellaris)

A 2km ring world?
Elysium had entered the chat.
I ADORE your wacky sense of humor while delivering digestible science.
Forerunners were also meant to have the tech to just make full on planet sized gravity forcefields and stuff. Maethrillian didn't use rotation to simulate gravity, and neither did the Ark.
Even humanity had "gravity plating" of some kind in its space ships by the 26th century in this setting.
Another person who is showing their age, I made the connection to Niven's "Ringworld", and his need to create Skrith, the material with enough tensile strength to hold a solar system sized ring together. Question about the viability of the 2 Km ring, what would the gravitational gradient be for an average height human standing on the ring interior. If the force of gravity at your head is different enough from the force at your feet, that can cause discomfort.
I KNEW RINGWORLD WAS A THING!! Every kept saying "You mean Discworld?" (Which I did...) but everyone was like "Ringworld isn't a thing." Glad to see I am not completely crazy. (There are parts missing:p)
I was scouring the comments for another Ringworld fan... I discovered the series last year and I've been kind of obsessed with it since.
I don't know the exact number but as I've heard that much smaller cylinders are practical, I imagine it is likely negligible to a human.
@@iciclecold2991Ignore the fools, your mind is superior.
Excellent video!
Also, I personally like to imagine that Halo plasma grenades stick because they are covered in some sort of shock-activated adhesive compound and that they (unrelatedly) glow because the reaction (or charging process, or whatever) that generates the explosion emits so much light that it shines through the container.
They literally have a button on them that you press before tossing them, like a pin in a regular grenade.
if ISS stops at place suddenly (1sec long deceleration), then the astronauts would feel about 8000000% of their weight at the moment of their contact with the wall
Science-tacular. Love it. Great video, as always Kyle and A.R.I.A. Keep up the great work!
Hey @Kyle Hill, returning Super Nerd here. love the show, the episode, and the video game series, so I have some thoughts on the Plasma Grenade.
I've always thought the plasma grenades use the electromagnetic properties of plasma to magnetically bond to the target until they explode. They aren't always glowing, and have to be activated first. Once thrown I have always assumed it's about the impact that activates a magnetic effect which clings to metals found in the target. This makes sense because they can cling to metal armor and vehicles alike. This does not make sense when they cling to the bodies of the Brutes (a nickname of one alien race), who sometimes forego armor entirely in favor of their hairy and thick near bullet proof hides, or the Guta, another alien species of giant gorilla like animals found on the planet Reach. It's possible that these aliens have a high metal content in their bodies, possibly their bones, especially since Brutes invented electricity throwing weapons when they were at war with one another before joining the enemy faction the Covenant. Maybe they are susceptible to electricity due to some ferrous properties of their bodies, so that's what they used on each other. However, it seems odd that they and the Guta alike both possess ferrous properties while being the only fleshy targets we ever throw plasma grenades at. That's a major coincidence
The truly strange thing is really what the plasma grenades do and do not "stick" to. They will stick to a person, but not a wall. They will stick to a vehicle, but not a crate. Clearly the "stickiness" property is controlled, and the grenade has some kind of suite of sensors and computational ability to determine what it has struck on impact, and will only then stick to the object if it "wants" to. Otherwise it's unlikely that such a system could be so particular about what it sticks to. For example, it may produce a complex magnetic field that acts as a sort of 3d scanner, like an MRI by making use of the magnetic properties of the plasma contained within the grenade which is later used to create the detonation. But regardless of how it determines what to stick to, it must possess some kind of radical method of sticking because it deals no damage to the target until it explodes. This is the main reason I am disputing your idea, Kyle, that it's melting the target or itself to create a form of adhesion. It must be some kind of mechanism that's relatively harmless given the circumstances and lack of damage until detonation.
I suggested magnetism despite the few inconsistencies in ferrous materials, but it could also be something chemical like a snail's fluid due to how they're manufactured. See, the plasma grenades are manufactured by yet another alien race in the conglomerate known as the Covenant. These are nicknamed the Engineers, and they possess tentacle appendages that can warp their shape to form many tool like structures and create small artificial gravity fields. They also hold many materials separately inside themselves in bladders for construction, and have minds that can reverse engineer new technology in minutes. They do all of this because they were not evolved, but rather created by an extinct ancient alien species. They're actually biological robot construction workers and inventors, hence their nickname. Anyway, since the plasma grenades are manufactured by these biological creatures, they may possess some kind of biological solution to this problem in the form of a sticky solution of chemicals which the grenade secretes just before impact. This is also interesting with the MRI scanner idea because the Engineers are 100% peaceful since their minds were programmed not evolved, and they're enslaved by the Covenant. They always make tools of peace, but those are then warped by their commanders on pain of death into tools of destruction. If the plasma grenades started out as portable MRI machines for medical purposes, or maybe a means for the blind to see in magnetic resonance, then they might have presented it to their enslavers only to be ordered to make the plasma core overload and explode on impact. The stickiness might have originally been meant to stick the device to a wounded individual or damaged vehicle for diagnostics, hence why it only seems to activate on impact with those things. The plasma core might have been both a power source and a means to produce the MRI effect of the device. All of this makes sense within the confines of the Halo universe, and it bridges the gap substantially between the fiction and reality if it were to be made canon for the series.
If I'm not wrong the explanation is that when activated they start to leak their inner coolant which is why we see gas coming out, and eventually this coolant not only vents but covers the surface of the grenade making it sticky, without coolant inside then the core of the grenade collapses and creates the reaction we see as an explosion, this however doesn't really explain why it doesn't sticks to terrain but it does on small vehicles and infantry, I mean, that's probably because gameplay but, it's a quite interesting characteristic of the plasma grenade
Issac Arthur does this one too, and if you stack up a bunch of the 2km rings you get an O’Neill cylinder (2 L’s!). That’s what I want to build, after the other ring structure!
I understood that reference.
Both the questions Kyle asks in this video have answers in the lore, I think Spartans have a system in their suit to handle puke in the event they throw up, and the plasma grenade's core heats up the paint on the outer layer causing it to become sticky
but then it would stick to anything. not just targets.

@@frogz Oof. Now that's a kick in the nasties.
The Expanse does the best job of showing this with how their ships move through space and how they are configured internally.
Main problem is the interiors of the Expanses ships are way too big for what the measurements apparently are. Otherwise they are very practical and realistic given the Epstein drive yes.
For a good example on how to build them would be to look at the way Iain M Banks describes The Culture's orbital rings.
OMG I’ve been binge watching your old videos on nerdish and because science and I thought you were gone I’m so glad I found this channel😭
Great video! Cononically halo rings actually do use artificial gravity generators and only use the spinning as a backup way, but.... few people actually know that and isn't that important if a detail.
The Forerunners made a big deal about certain technological feats that had to be achieved in order for a civilization to attain "rank" one being able to condense matter, demonstrated by Spartan Mjolnir armor (the MC's armor weighs around 1000lbs), another was being able to subvert the laws of physics to build megastructures. This was something Humanity had yet to accomplish.
That said, the Forerunners had, through some variation of Active Support, a means of using active vectors of force, energy beams, streams of particles, to hold stuff up. This version being able to hold matter together under even the most insane forces. Think Star Trek's "Structural Integrity Fields" that allow actually structurally unsound vessels (as most Starfleet vessels are) to survive the stresses and strains of just maneuvering with any degree of interest to being shot clean through and not collapse [or] shatter.
In this way, the HALO rings are 5000km radius and not fling themselves apart. It also helps that they are not spinning very quickly at all, relatively speaking.
Forerunner’s power their megastructures on the energy of dying universes
Do they spin tho? They don’t really have to.
@@dr.catherineelizabethhalse1820
They have to in order to generate artificial gravity. much more believable and sustainable than powering gravity panels.
@@slimerewoods5766
It's easier to spin also, actually watch the cutscene s in the actual game, Original version or Blurr's remaster, the Halo rings spin... albeit Slowly.
@@slimerewoods5766
The ring, because of its orientation to the planet it orbits, gets its day-night cycle orbiting the planet , passing through its shadow.
Otherwise, to accomplish a day nioght cycle, the ring would have be spin 'like a coin on it edge. This would destroy the ring becasue it would begin the stretch toward the perpendicular of the axis of rotation. Aggravated by having MORE MASS being directed, actually and/or by inertia, the ring could not hold. The ring would NOT have its of biosphere. To resist such forces, would require more energy than it is worth.
Your notion does not work based on what is shown in HALO and what is known in real life of physics.
The Ring spins along its circumference to generate gravity. It is easier, safer, harder to subvert, and reserves energy for the rings main function as a galactic scale WMD. Why expend the power for something you don't need power for, if you don't have to?
Whatever Clarktech solution the Foreruuners used is immaterial since were were talking about Artificial Gravity and NOT how they keep the lights on.
And I started this thread on how they ring would stay together as it spun. Again Clarktech but that made the most sense for what is shown in HALO and in Rel live is known of physics.
Clarktech? Please refer to Arthur C Clark's Third rule "Any technology sufficiently advanced is indistinguishable from Magic. (Paraphrase)"

*Captain America voice* I got that reference
Also, for the Plasma Grenades sticking, I always figured it was because, while emitting the light and energy aura, it wasn't "active" until you clicked and threw it. Upon clicking it, it'd activate its internal components and, after a second, become "sticky", either through a chemical reaction or electro-magnetic coating, allowing you to have time to throw it but also allowing it's other effects to work within canon
“Bet you can’t stick it”
It melts through things so it sticks
For the plasma grenade question at the end, is there an adhesive that could retain its ability to stick at such hot temperatures? To activate the grenade ingame you first press a button on it, perhaps when pressed it starts secreting an adhesive on the surface of the sphere? Picturing something like how a poison dart frog secretes the poison from its skin when threatened.
It takes the grenade a number of seconds to explode anyway so it doesn't instantly turn into a ball of plasma right away, so it could possibly work. Adhesive gets secreted onto the surface of the grenade, internal temperature of said grenade heats up while getting ready to explode, the adhesive helps the grenade attach onto a target, then gets melted away along with whatever it was attached to upon detonation
But you obviously don't want the adhesive to be secreted immediately because then it would stick to your own hand.
I believe the in-universe explanation for how the plasma grenades stick is that, once thrown, the grenade heats up so much that it melts into things to stick to them. I could be mistaken, as it's been a while since I read the books. But I'm fairly sure that's how they work :)
@@damienstitchman1981 I remember seeing that in the books as well
Only thing I have against that explanation though is energy shields
Your shields ingame don't go down when a grenade sticks to you, so the grenade with this explanation would have to melt an energy shield(Although if we look at a Jackals energy shield, a plasma grenade bounces off of them)...did we just find a plot hole in Halo?
@@NecronNate You know, I'm not quite sure what the explanation there would be. Every time I think of something it comes back to the shields not going down. We might have discovered a plot hole here!

If anyone could talk theoretically about the topic, it would be Kyle
And so Aritana went insane, blew up the Brute homeworld and held the entire UNSC hostage under threat of massive EMPs, all because Kyle couldn't help fanboying it up.
Kyle the plasma grenade could have an adhesive strip on it. >.> just pull it off when you throw it, or maybe push a button and it becomes covered in adhesive except for a specific section you hold it by? what I really want to know are how the needlers are able to home in on targets when their ammo is basically crystal, same with the needler supercombines, how do those work? could they work?
I don't know how many people know the lore behind them but they were all designed to be put in like an array and they actually got used to wipe out all sentient life in the galaxy at one point in the halos universe so the forerunner secured their own shield worlds " " to hide from the blast and the humans inhaler are supposedly descendants from the forerunners
I think we should keep blue AI ARIA as seen in this episode
Might have been worth noting that a 5000 km ring would not need a "roof" to contain atmosphere. A 2km ring would either need to be roofed, or to actually be a hollow disc.
I was just wondering that. Can you expand on why?
With Earth's gravity you would just need a ~150km lip around the edges to keep air in. Nothing between you and vacuum but air. Think about how thick Earth's atmosphere is and it'll make sense. Have some very tall 'mountains' around either side of the ring.
I've been wanting this video for the longest time, most people say yes, but I've been thinking "doesn't gravity and the spherical shape of earth stops the sun radiation from tearing the molecules that made the atmosphere from being easily torn? Wouldn't that be way too easy if it's just a ring around a sun?"
Edit 1: Apparently what keeps the earth protected is the magnetosphere that exists thanks to the core of the earth. I think it gives it away, can't hardly have a "magnetosphere" without a sphere, but beyond that, making a system of cable rigging around the Halo to make it have a magnetic ring to protect the atmosphere would be a resource nightmare. It's already the opposite nightmare the idea that we would need to do that to give Mars a magnetosphere to let it have atmosphere and make it liveable.
The core is what provides a magnetic field for earth and that’s what protects the atmosphere from being torn apart…and no you wouldn’t be able to wrap the halo around the sun, it would have to be far out and tilted so it can receive sunlight at different times like the graphic showed.
afaik nope, magnetosphere yes, round shape no, the ring is something we could in theory build, as in 'how' is basically understood (Active support is absolutely necessary, think a hose pipe going rigid as the water flows, that is active support at it's simplest.) Isaac Arthur explains how in his megastructures series.
@@justicar5 But doesn't the name "magnetosphere" give it away? It's hard to have a magnetosphere without a "sphere", without a center providing magnetic protection from the sun radiation to keep the molecules in the air from ripping away.
@@scoobertmcruppert2915 But aren't the Halo rings all built and set around suns?
it's not the shape of earth preventing the solar wind from tearing apart the atmosphere, but earths magnetic field, driven by earths molten core. Thats the reason mars doesn't have an atmosphere, but earth and venus do. No molten core, no magnetic field, no atmosphere. I imagine it would take immense effort and huge amounts of energy to generate a magnetic field big enough to protect the atmosphere on a spinning ring in space, not to mention that the spinning itself would probably catapult the atmosphere away, since it can simply flow around the ring into space. A glass dome on the inside of the ring would likely be way easier and more practical (and much easier to explain than an imaginary device generating a magnatic field)
I hope we will all be so lucky to find equally nerdy partners that will dress up as video game characters for us. It’s great to see there’s a face behind the voice
Excellent video as usual Decaf Thor- I mean Kyle!
I wish more people knew about Ringworld, what the Halo rings are based on. The novels by Larry Niven describe a ring that, instead of orbiting a gas giant, replaced an entire star system. I grew up with Halo, and it will always have a special place in my heart, but Ringworld was Halo in 1970. And a hell of a lot bigger. Using the equations in the video, I learned that Ringworld spins at 0.000774 RPM. Someone please correct me if my math is off, I tried to do it on my phone lol
Great video Kyle, always an entertaining and informative adventure. I'm wondering if you could possibly go into the science of such a ring orbiting the earth and how it would effect people/Spartans on each side of the rings acceleration. Would the motion of the ring orbiting cause acceleration/deceleration of objects on the advancing side of the spinning ring compared to the side spinning the opposite way of the orbits travel?
If it would, I believe the force would be almost undetectable.
Still waiting for an Expanse video game with realistic physics, where everything (more or less) makes sense.
Have you tried "children of a dead earth"? It's a bit _too_ realistic for my taste though (as in: extremely pedantic), and suffers from a case of "programmer art" syndrome. Other than that there's only Kerbal Space Program, I think.

Hi Kyle! I was wondering if you could make a video on how the hangar shields work in Halo, Star Wars, and other sci fi videos/shows/games. They trap air, but let more dense objects through. Is this possible by any means with our current technology? If not, is it something that is theoretically possible in the future?
Not sure about shields, but a barrier of something like self-sealing, highly elastic but prone to puncture material *could* work. Trapping the air inside, letting ship pass with some force, then sealing back and retaining most of the air inside. Although, anyway, it would *not* be transparent. And would probably feature somewhat limited number of uses until a replacement would be needed

2 km Halo ring... And what would You call a mutliple 2 km Halo ring set side by side? Well, an O'Neill Cylinder :D
And the living space that You would loose due to shrinkage of the ring's radius, You would recalim it by making the ring wider. So wide in fact, it should be considered a cylinder, not a ring ;)
Halo ring has a little under 1×10^7 km^2 of surface (one side). To get that kind of surface on 2 km diameter of cylinder, it would have to have almost 1.600.000 km of length.
It would be a hell of a straw XD
But, if we shrink the ring proportionally, the width would be 63.6 m XD That would be pointless. The surface would be around 0.4 km^2 (under 100 acres). No, that just won't do.
Lets get 1 km radius ring but with width of 10 km (a tube 5 times longer than wide). I think that's reasonable. That would give us 31.42 km^2 (7764 acres). Not much, still, but way better.
My point is this - rings are good if they are (very) big. If scale is small, you're better off with an O'Niell cylinder ;)
And if its that wide, you actually feel like you are walking in a big space in space😂
Kyle hill…..the mad genius who answers the questions my brain asks when im awake at 3am
At 5:58 and I'm already thinking about the water bucket experiment. You tie a length of rope to the bucket handle and fill the bucket with water. You then start spinning the bucket by the rope and the water stays inside because it's feeling force in 2 directions: an "outward" pushing force and a "forward" pushing force.

Halo rings generate artificial gravity through generator facilities in the ring, not rotation. In fact, I believe they are more like ring-like starships, as they can travel, including at FTL speeds. However, they do not rotate.
They do rotate, but only for a day-night cycle.
@@avatariroh0543 even then, they rotate in a perpendicular fashion
an alternative to a 2km ring would be a 2km tether between two equal mass modules or shorter with a heavier counterweight at one end (and longer for a lighter counterweight) so long as it's not intended for habitation. you could have this perpendicular to the thrust axis but a better idea might be parallels to the thrust axis. this means no need to change the orientation of the living spaces between thrust gravity when accelerating, and spin gravity when coasting. just lay out your ship like a skyscraper, with the thrusters at the base and a tether + counterweight system at the top.
I would say that an O'Neil cylinder is a far more realistic approach.
Random conjecture;
Maybe the plasma grenades either have a built in electromagnet that activates when it impacts something metal like master chief's armor or a warthog? OR
Perhaps the plasma is generated by intense electromagnetic induction and the field makes it stick?
That or maybe they just modeled them on sticky grenades from WW2
If you want an open top atmosphere instead of a tube world you'd need walls on the side of the ring that are high enough that the pressure of the atmosphere would be livable. And since the artificial gravity tapers off quicker than real gravity as you go "up" that means thicker than Earth's atmosphere. So that 2 km Halo would have to be a tube or a completely sealed disc 🤔
They use artificial gravity generators throughout the halo ring to generate gravity, not rotation… and the walls on a halo ring are something like 200km in canon
@@smallpeople172
Yeah but since this could theoretically be created and anti gravity probably isn't in the cards for us, that's something we would have to do to keep the air in.
@@mill2712 yes but why analyze halo megastructures through our physics? Its a game. Its like analyzing Santa Claus through the lens of astrophysics...
Building a ring as a kind of habitat or spaceport (or whatever other function) only makes sense as step one. Once you get your ring, you'd expand outwards from the edges of the ring and start making a cylinder for more surface area. Making a gigantic ring with a huge diameter looks cool, but from an engineering perspective doesn't make sense because you're going to need rarer and more expensive materials the wider and wider it gets. Making the cylinder longer wouldn't require any different materials and would be logistically easier as you wouldn't have to disconnect the ring and add material (and somehow keep it from flying apart), and stitch it back together again; or stop the rotation (which means everything would have to be strapped down)
Also, you wouldn't build a single ring but probably several "rings inside rings". The reason you would do this is the closer to the center you get, the less the apparent gravity. So, your inner-most ring would have very little gravity and would be useful for literally heavy manufacturing, bio-tech, and probably a host of tons of fields of research.
tl;dr -- build a cylinder, which is really just a "thick" ring. It's got more surface area and can easily be expanded outwards. Also, build rings inside of rings so that you can have lower and higher gravity areas for various different functions like low-grav manufacturing.
Welll. Harmonics has a word to say here too.
You really need two cylinders linked together, and that can impose practical limits on the diameter, and the issue of the bearings joining the two wearing out and something like this you want to build for the next few hundred thousand years, and there is the issue of lighting.
Again. Really long lifespans for an artifical planet so your better off just using a really long lasting source, a star.
And then.
You still end up going for much smaller diameters because you do not want any active support schemes that could break down.
There's a lot of reasons the O'Neil cylinder was space island 3. It might not ever be practical, but one and two definitely should be.

The plasma grenade would make more sense if it only stuck to armor like Kyle said. The plasma might sit on top of the energy shields. Allowing someone to throw it as long as their shields are up, but if you try to grab the grenade with your shields down, it will stick to the users own hand, and it won't stick to a target if the target has energy shields up.
IIRC, the main issue that comes with Halo rings creating artificial gravity by spinning is that trying to land on the ring would be difficult since you risk crashing or burning up in atmosphere if you don't match the ring's rotation on approach
Could be solved if you're willing to trade a ring for a wheel. Spokes connecting to a rotating docking collar in the center means you'd only need to park next to it and match its rotation like in Interstellar.
Not that difficult, I think. Approach the surface from the edge, match the rotational velocity and then hoop over the edge to the landing site. But you would be able to land on them only in the vector along their direction of rotation, and you'd need to compensate for the ring trying to constantly escape "up" from your POV.

The type 1 anti personnel grenade aka The plasma grenade has the plasma contained within the casing, there is a primer button on the case of the grenade, the casings magnetic function activates on a timer after the primer is pressed, the grenades explosion is not on a timer but is triggered shortly after the grenade is accelerated and then comes to rest! You can throw plasma grenade to any distance and they will not explode until they stop moving.
I love how super obvious it is that the coffee cup in the outro is completely empty and always was.
Dealing with the coriolis effect in a rotating space habitad could be a very good mechanic for a First Person Shooter.
The Ringworld Books got this treatment between the first and Second book. The Foreword for Ringworld Engineers Begins with Larry Niven Telling the reader that he received so much fan mail from people of several scientific and mechanical specialties, who really enjoyed ringworld...but had to explain to him why it couldn't work.
In the original book, the "scrith" is distinctly not normal matter. It is represented as a form of degenerate matter held together by strong nuclear force. Like neutronium but blocking 40% of neutrinos.
Ktle, I think the plasma grenade works like a normal frag, but it has a fuse time that starts the Casing as a metal that will stick as it melts. John pushes the primer, the core begins to warm up, in air the casing splits to regulate temperature so that the casing can attach by the melting polymer it was, then the pressure from the plasma is too much and explodes the molten metal at high speed. The casing probably has time from priming to detention that it is still safe to throw. In some of the Halo games(if not all of them) you can throw the plasma grenade up and have it land and stick on you.
