I think this gives one choice in The Amazing Spider-Man 2 some credibility. Instead of falling off of a bridge and having the chance to survive, she falls from the top of a clock tower and smacks her head on the ground. No amount of spider-silk stretchiness could have saved her in that scenario. So maybe the writers of that movie considered this when making that change!
Cameron Lightfoot, SM does catch her, but so late in the process that there wasn’t enough time to decelerate much. She even bounced back up (too much).
I actually loved that scene in the movie because the entire time your teased back and forth with are they actually going to kill her or not. They even make it look like they are going to go against the comics and actually have her live, then they snatch the rug out and give us an even more brutal end. I still remember the theater starting to groan/cheer that he saved her to that loud thunk and the immediate silence of the audience.
But SM 3 (i know we don't talk about SM 3, no one should) her head is still snapped backwards and breaks her neck even as she was slowed down before stopping.
I thought she died in that movie from her spine snapping and I dont remember seeing her actually hit the ground. Guess I gotta comb UA-cam for answers now lol
It's already obvious that she would die. Because the whiplash wouldn't kill her, but the unnslowed down force of her head hitting the concrete would. Being dumb, Andrew Garfield's Spider-Man aimed for her torso, when he really should've aimed for her chest.
@@sixela6 Yes and no. Mythbusters proved they both could have gotten on the door, but you would have had to add the life preservers underneath to increase the buoyancy. The easy out is to simply say that neither Jack nor Rose understood those principals and therefore never knew they could both get on by simply doing that.
@@Kmmlc That, and uh... it was below freezing tempatures in the middle of the ocean. Rose's brain was probably doing everything it could simply concentrating on not going into shock.
@@sixela6 There was a ship full of debris, furniture, and safety equipment floating all around Jack. He could not have climbed on to what she was floating on, but there was ample stuff for him to float on. But, because movie says the good guy tragically dies, he dies. God, I hated that movie.
Good question. I went ahead and did some math myself and the answer I came up with is: a lot (or "fucking hell, that's many!", depending on how exactly you round up your numbers). You're welcome.
@@becausescience look forward to that 1, as soon as I saw it in the cinema I started thinking about it. Trouble is every time I think I'm done I spot another variable I missed. I would suggest doing a simplified version like you do sometimes.
Hey Kyle! You calculated Gwen as a single point of mass, but a falling body is far more complicated than that. You do mention it briefly further into the video, but the acceleration from rotation could actually increase the velocity of her brain case (think of a waterskier going faster than the boat when turning). This acceleration then deceleration would cause severe brain trauma. So how she's falling and where the web connects are vitally important.
I was thinking about this from the very beginning of the video. I don't even want to begin to try to calculate how far she could fall before there would be life-altering trauma to the brain.
I'd be more concerned with when the web catches her that she'd then swing into the bridge itself. Because the web is holding her by the ankle she'd almost certainly hit the bridge head first... Which would have a decidedly non-pg-13 effect on her skull.
@@thatonedemonchild624 first of there's is no disrespect in my comment. Second of all is the truth, the only way he can rest in peace is if he accepted Jesus as his lord and savior.
Well there is a detail easy to miss that you miss in the panels. There are three panels of Gwen falling first of her upside down, second of her head upwards (her hair and hand are both visible facing up), and finally the one with the web on her leg of her facing down again. This might mean that she was spinning while in the air.Wouldn't this add a rotation? by pulling her leg upwards while her head is going downwards it increases the Gs that her neck and brain is suffering. I mean there is a reason why people try no to spin vertically while bungee jumping aside of a few broken ankles you risk to suffer a hypovolemic circulatory shock by all the blood rushing in a sec.
she would have to be tumbling at 31 rpm (assuming she is 6') to generate 1 g on her head. and that would mean she was spinning at running speed, not likely. so the tumbling wouldn't make much difference.
The sad part is Gwen Stacey is dead... but at least we know that of the different versions, the more realistic one was the one in which Gwen Stacey fell more than 42 meters.
Her head could have torqued back , depending on directionality of her rotation as opposed to the web's vector causing the skull to pull from the atlas vertabrae which in turn causes the medula oblongata to strike the base of the skull which causes it to swell which in turns stops autonamic nerve function leading to a coronary. Had spiderman given her CPR she would have survived. A strike to the base of the skull to cause thia if I remember correctly is about 3 psi.
@@scotthenderson4687 , @ruyman90 Come on now, you guys are just throwing out terms and conditions ; hypovolemic circulatory system shock? New to me. And Scott, you a biology major because medically it's normally called a herniated brain stem. Just curious...
Reckec I did not major in bio, but have taken a few medical related courses. I refer to the medulla oblongata which is a part of the brainstem that controls autonomic function of heart ,lungs, body temp regulation etc.. I also studied martial arts and as such reenforced my knowledge from A&P courses. And i used that knowledge to determine why she died instead of could she have survived. The injury I described is well documented in medical text. As results from auto crashes induced by heavy whiplash, as well as getting struck in the back of head.
Hi Kyle, i believe there are many additional factors to consider that would ultimately make the chances of gwen surviving much less likely. first off we know spidermans's web slinging usually reach a wide variety of ranges to reach the different distances that he needs to traverse. this would mean spiderman would not only have to catch her with his web, but he also needs to stop shooting his web at the right moment so that the length of the web would stop extending at the right time to stop gwen's fall before she hit the ground. So factoring the mental stress to catch her in the limited short time frame he has to work with and to not over extend his web after catching her, it could come to reason that spiderman may have undershot the required length of web to catch her, which would mean the web silk that he shot was already stretched close to its tensile limit when it caught her. This then reduces the amount of cushioning effect his web would have on reducing her fall speed. We can also prove that spiderman's does shoot his webs with such force that they usually do hit the target close to the tensile limit of the web on a regular basis. *anytime he shoots at a high point while standing on the ground, the web shot would usually launches himself into the air to allow his trademark web swinging action across the city. while i myself am not too sure on the calculations to figure out how much tensile strength is required from his webs to pull him up into the air with enough elastic force, but this does prove that spiderman's web threads do get launched and stretched prior to hitting his target on a regular basis, and if his catch immediately pulled back on gwen after catching her, that only amplifies the halting speed of her fall rather than safely slowing it with a cushioning effect. TL:DR spiderman shoots his webs pre-stretched so the web pulls back on the fall rather than slowing it safely.
Elryx how would one shoot something pre-stretched if there's almost no force being applied to it? Also, staying rigid would make a lot of things in the movies VERY GRUESOME
chingcongwong the third I worded the tldr badly, my assumption is that the Web stretches as it flies through the air and therefore is more inclined to pull backwards from the elasticity upon hitting the target, rather than catching Gwen with the precise amount web required so that it is has extra room to stretch and cushion her fall. Edit: there's definitely force applied to the Web shot out, otherwise it would simply spill? below spider man like tap water when he shoots the web
So what you're saying is that Spider-Man would carefully have to solve "how do i shot web" in order to save her? Also even if Spider-Man perfectly calculated the length of web required for the calculation of the intercept path that it would have to take for its deployment velocity, a pencil-thick material of almost 42m moving quickly enough to intercept a freefalling Gwen would have its own energy to have to account for when it comes to the stretching that occurs after its mass joins with Gwen's, contributing to the stretching parameters it would be experiencing once the line hits its limit. What you're saying about Spider-Man's normal transportation webs assumes, after all, that the webs themselves deploy with enough velocity to stretch itself such that he would be snagging his anchorpoints with an elastic burden already applied to the line such that he can propel himself with them. THAT BEING SAID, however, how do we know that it's a consistent web that he's shooting? He's demonstrated already that he has several web-slinging techniques at his disposal, there's nothing that really dictates that this pre-stretch technique is what's being deployed here. And going beyond 6G isn't even a death sentence either, people experience instantaneous forces of hundreds of Gs in car crashes and survive, so there's room for play as well. It might very well be Gwen survives with recoverable injuries related to her deceleration, the margins are wide enough.
@@stuchly1 Hey joke's on you, what I just said was literally verified in the Live followup show XD The word you've forgotten to take into account is "instantaneous" forces, I'm not talking about dropping a couple tons of solid lead because that would crush you dead for a solid tenth of a second or so, which is a lot of time to take those forces on your body and a lot of total energy transferred that would have plenty of time to apply breaking stress on all sort of body parts. Do a little google, it's actually a really fascinating subject.
So, if Gwen were *pushed* off the top of a bridge, there'd be some lateral velocity too, right? She wouldn't be falling straight down, strictly speaking. So regardless of whether or not there was enough give in the spider silk to safely arrest her fall, if Spider Man was standing on the top of the tower of the bridge, Gwen would be slowly moving laterally away from him at the velocity of the initial shove. Therefore, when the spider-line catches her, all of her lateral movement would translate into gravitational potential energy, and she'd swing back into the side of the bridge, upside down, and probably head first. Probably not healthy. Also, don't most of those bridges taper as they get taller? They have a big central base, and then occasionally step in as you get higher up? If one were falling off the bridge, and impacted one of those steps, especially if falling head first, it'd do some damage!
@@christianlang348 They are actually right, there would be some lateral movement and Spiderman wouldn't be directly above her which would create a pendulum effect on her when the web-strand reached it's maximum length which could swing her into the bridge supports. Air resistance doesn't really come into play. So ... Just no.
There would be a lot of air resistance cause by the act of covering a large distance quickly, vertically. Any lateral movement would be dissipated very quickly after falling by the large amount of air on the way down. With no air, yes, they would move more, but factoring in air friction and aerodynamics, not so much. So again, no.
What if the Green Goblin already killed her before and just threw her body? That would be a great villanous way of getting Spiderman to blame it on himself. I would do that. wait. I'm not the Green Goblin. I'm just insane. About your show. Edit: If he would have killed her BY swooping her of the bridge with the glider, that would pretty much work and look the same , she doesn't even scream.
@@dillonchaddick695 With the Goblin's abilities he could have easily killed her after she cries out and split seconds before the toss. Part of what made that comic great is the Peter could never truly know if it was he or Osborne that caused her death.
Nice analysis, Kyle. But, there is one factor you didn't consider. The spider silk has to attach to her body strongly enough to arrest her motion. Even if you assume Ol' Spidey has invented a quick-drying adhesive strong enough to support a human's weight (he does swing from his webs all the time, so I think that's a fair assumption), the web is only attached to a very small section of Gwen Stacey's skin. According to a study by Gallagher et al (see reference below), the mean dynamic tensile failure strain of human skin is 25.45 MPa, plus or minus 5.07 per cent. If we assume Peter Parker's web is attached to a one centimetre square area of Gwen's skin - and because 1 mega Pascal is equal to 1 Newton per square millimetre - Gwen's skin needs to be subjected to less than 2,545 N of force, or it would likely just be torn by the web. Since our hypothetical Gwen has a mass of 50 kg, and is falling at 29 m/s, she has a kinetic energy of 21,025 J at the moment the web contacts her. Unless I've completely messed up the math (which is quite possible, high school physics was a LONG time ago), Gwen would have to decelerate over a distance of more than 8.26m (say 8.5m to be safe) to keep the pressure on her skin below the tearing threshold. I think that would actually work, given how much some spider silks can stretch, but it's something that is worth considering. Cheers. EDIT: Put another way, at much above 5g of deceleration, Gwen's skin would fail before the web did. And if Peter liked his webs thin or his girlfriends thicc, she'd be in real trouble ;) www.ircobi.org/wordpress/downloads/irc12/pdf_files/59.pdfMPa
@Arthur Williams on the drawing it is shown as 5 strands , like a ribbon with bits going sideways like a mesh , but may actually be a mesh tube so it would have better grip but also less springiness , if it was a bridge over a river she maybe would have been better going into the water , also the web looks like its wrapped around her leg so it would hold :-)
YTANDY100 Yeah, I was taking a look at the original illustration again and it is hard to guess the total surface area of the web in contact with her skin. But with it wrapped around her leg, as it does appear to show in one panel, it would have a pretty substantial amount of contact. If each of those strands is 1 mm wide, and her ankle is 200-250 mm in circumference (around 280 mm is average for American women today, but Gwen is slim), then we’re talking 10 to 12.5 cm2 in contact area, dropping the force on her leg well below the skin tearing threshold. It would probably hurt to be stopped that way, but as long as the web is stretchy enough it would work and she’d survive.
Great video, Kyle. My wife and I love your show and I especially love your Spider-Man centric ones. Couple of things though; I know you based your calculations off of real spider silk, but Peter is constantly updating, changing, and making new variations on his basic webbing formula. It’s possible he had something with less elasticity at the time. Also I know it’s hard to tell because it’s from a comic book page, but do your calculations take into account the possibility that in a panic maybe Peter pulled up on the webbing as it caught Gwen? He does have superhuman strength and it’s been documented time and again that he holds back. So in a panic, maybe he pulled up on the web just a little too hard, reducing the cushion the web would have given Gwen during her fall. This is the love of his life, so him being a little overzealous would be plausible.
I've always wondered, how much "web fluid" can the small canisters in his web shooters really hold? They're small and he shoots a LOT of webbing before he runs out. Also, it's not the fall that kills you, it's the sudden stop.
bungee jumpers fall and are arrested by bungee in a similar fashion. Judging by the comic frames, there looks to be only one ledge that between her and the water in the catch frame, being that the tower gets wider, she must have had some horizontal velocity leaving the top. Now, without me adding more math to this, i will add a few thoughts. spiderman was at the top when he caught gwen, who was in your video halfway down. at that point (approximately) the tower gets larger. Accounting for the horizontal velocity and spiderman being closer to center than her, when arrested she would have flung into the tower. Kyle, you rock climb so im sure you are aware that its not fun to fall and then swing into the object you fell off of because your lifeline is attached to it. Gwen fell head first so i assume there was some blunt force trauma between her head whiping under her pivot point and the side of the tower. that leaves worse imagery than the comic... possibly why it wasn’t included.
RockoSpaz86 bungee jumper has a ankle grip surrounding both feet. I don’t think the spider web would surround her foot. Also usually Spider-Man’s web usually is shown sticking to a Surface. Which means sticking to shoes, boots and pants. That could be pulled off when the web stretched. So she would fell pant less after smashing the bridge.
Hey Kyle, cool episode. Gwen was the best and I would have loved for the scientific outcome to have been canon. Two things that might explain why she does die are 1 Like you said, she may have fallen at an angle. In the comics you showed, she seemed to be falling horizontally. So if spiderman caught her by her legs, her body would have started rotating, which could (mind the word 'could'; I'm not sure) have caused a whip-like effect that would snap her neck, literally cracking it like a whip. 2. If spiderman caught her below 28% of the height of the bridge (so the stretch length remaining would be less than 40%) She could have simply hit the floor below. Then the spider silk would have helped her stay perfectly vertical, so that her head would be the first thing to hit the floor.
Kyle, we’re gonna have to agree to disagree. In the iconic panel, we can see that Gwen is arched and her head is snapping backwards. I think given the visual evidence given, we have to assume she pivoted on her heel once Spidey caught her. Using your numbies, a radius of 1.57 m (via your used wt and the Hamwi formula), and the centripetal acceleration formula of F = m * v^2 /r, the slowest F I can get is 9642 N applied to her cervical vertebrae. From my research, it takes ~ 4400-5600 N to fracture the cervical spinal column. Poor Gwen is still doomed.
I.E. a weird angle, exactly as Kyle (?) mentioned. He never said Gwen was guaranteed to survive, just that, given the information Spidey was working with, the solution that was attempted could well have worked.
I think the writers of The Amazing Spider Man 2 figured out that the math was just as you said Kyle and there for made it so Gwen's head hit the ground. But you know in comic books nothing has to make sense for it to be entertaining or tragic. Great work and love the vids.
In the beginning you mentioned whip lash. This usually causes injury in apegdages such as a neck, by first accelerating the appendage (in this case a head attached to a neck) parallel to the velocity vector, followed very quickly by the neck accelerating in an arc perpendicular to the velocity vector, thus the neck quickly dislodged and causes "the injury." She might die by being swung in a weird way even if she fell a smaller distance. Edit: Kyle mentioned this case at the end of the video. Opened my damn mouth too early.
You can type it and wait for the video to end before posting it. This way if you think of any further comments you can post them within the same comment without the need to edit it. Unless you're on a phone, in which you still can cut the entire comment and paste it again after watching the video but it's too much of a damn drag and I understand you in that case.
Spider-Kyle! Spider-Kyle! Does whatever a Spider-Kyle does! Can he swing from a web? No he can't, He's a man. Lockout! He is the Spider-Kyle! (But he can do some science!) Love the show thank you for all of that knowledge over the years.
Hey Kyle awesome episode. I think it’s ironic that you proved the stretch of the web would have saved her during the fall in the comics but the stretch of the web was a factor in what killed her in the Amazing Spider-Man 2 movie. Thanks for another great episode, keep on keeping on.
In comic Captain Stacy died when Spider-man fight Doctor Octopus and in movie it was when he was fight The Lizard, also Norman Osborn Green Goblin killed her in comics and in movie it was Harry Osborn.
thing is, spider-man's web properties and formula evolved with his experiences. It's not real spider silk, but an analogue. The death of Gwen stablished that his early webs were calibrated on strenght and elasticity more with spider-man and his villains in mind than regular people, and spidey is at least a couple orders of magnitude stronger and more resilient than gwen. And he knew this. But when Gwen was falling erred in panic and shot a regular webline instead of going for safer options. That's the core of his Gwen guilt, he got clouded in emotions in a life or death situation and he fucked up tragically. Since then most of the times he tries to push away allies and friends that could help him in his fights, because he doesn't want to put them and himself in a compromised situation again.
@@becausescience It is, but a little subtle (sprinkled here and there in the 1000ish issues ever since). Since then, everytime he has come across a similar scenario (a loved one falling off some tall structure) it's common to portray him getting a little ptsd episode in his head and as a result applying safer methods to stop their fall (jumping after them and shooting an appropiate line using his own body as extra buffer, web air cushions, extra elastic web beds, shooting fine elastic lines to several points in the falling body to spread the forces better, etc.
I remember reading about when Gwen died when I was a kid. I always thought that she died from fear, not from the sudden stop that snapped her neck. How odd.
Two major factors could have an impact here, one being a hypothetical, the other a canon fact. One canon fact about the original Peter Parker, he made his own webbing and shooter, creating the fluid that would react to the air and harden into his iconic webbing as he shot it out. So its plausible that his mixture has more rigidity than standard spider silk. Another point in favor of this possibility is the way his web seems to maintain length as he swings, rather than show signs of stretching during the arc of his swing due to momentum. Feats mirrored in newer media, showing the lack of elasticity, though there are exceptions. -Anything involving a train comes to mind. Though there are some free fall moments too, but those are a mixed bag. Some are sudden stops, others are slowed descents. But it could point to the fact that her falling did not carry enough energy to counter the rigidity of his webbing, given how much thicker it is compared to spider silk, and he made it with his weight and velocity during a swing in mind initially. He has also changed the composition of his webbing for various situations, so its consistency varied quite frequently, and may not have been suitable for that situation. For the hypothetical- I have heard of a medical condition/birth defect that could play a part in this to deadly effect. Weakened vertebrae of the neck and spine that left the individual more susceptible to trauma due to sudden jerks and concussions, or blunt impact to the back of the skull. Which could result in spinal damage that would leave one partially, or completely numb below the neck, followed soon by death. Such a person would be at a high risk of injury and likely be warned off bungie jumping, high diving, kidnapping by hobgoblins, and roller coasters.
Keep in mind that Spidey's webs weren't like actual webbing. They had settings based on his pressure on the button. He could have easily made it more rigid or other without realizing it.
Additionally what the comic doesn't calculate for is the potential dissipation of Gwen's kinetic energy if the web was fired at an angle. This would give an additional decrease to her velocity as she swings in an arc reducing the need for a strong flex to web.
Hi Kyle! I Love the show! And I love the hair! 🙂 James Kakalios in The Physics of Superheroes points out an even bigger basic misunderstanding flaw. Where Spider-Man receives a harsh physics lesson, and the Green Goblin’s scientific “genius” is called into question. At the last possible instant, Spider-Man manages to catch Gwen in his webbing, narrowly preventing her from plummeting into the river below. And yet, upon reeling her back up to the top of the bridge, Spider-Man is shocked to discover that Gwen is in fact dead, despite his last-second catch. “She was dead before your webbing reached her!” the Goblin taunts. “A fall from that height would kill anyone-before they struck the ground!” Apparently the Green Goblin, creator of such advanced technology as the Goblin-Glider and Pumpkin Bombs, suffers from a basic misunderstanding of the principle of conservation of momentum. Of course, if it were true that it was “the fall” that killed poor Gwen, then the implication for the fate of all skydivers and paratroopers would suggest a massive conspiracy of silence on the part of the aviation industry. EDIT: Kyle mentioned this at the very end of the episode... Well, still first like and comment. :)
You sir, have earned this like and subscription. Even though the distance, tensile strength, elasticity is all up for comic book debate, and blah blah blah, you always come out with such cool FUNducational videos. With so much real science and research poured into these videos, it really makes my favorite comics feel more alive. Keep it up dude 🤙
Hey Kyle Great episode, as always. Question, we covered the whether the web snagging Gwen would have killed her. But what about Gwen's position in the air? She was head pointed down like a dive, what if she was falling chest first like a skydiver slowing their fall? Or if she was falling back first facing up at the top of the bridge? Would the pendulum like snap of her swinging have done the damage necessary to kill her? Take Care and Be Well
the problem is that whenever the back of the head hits any object with enough force that blood comes out the nose(like what happened to lovely gwen) to much internal damage, the person is gone “unless an ER is within minutes to remove the back of the skull for swelling” then it is still iffy... emma did such an amazing job of making gwen perfect.. it is the ONLY death scene in any movie that made tears go down my cheek.. i still have a hard time watching it
You are not lying. Just saw that particular Spiderman movie for the first time a few days ago, and it affected me emotionally more than I expected. They had a great chemistry and the movie did a really good job of making you care.
Spiderman body would also have some give, being pulled by Gwen's bodyweight. He is strong enough to lift tons but he doesn't have an incredible weight (although his surface adherence might somewhat negate my assumption )
Glad I came through the comments. I was thinking about this as well. I think it would be pretty hard, but not impossible to math out. We need his weight, how well he adheres to the surface, his strength, and his body posture. (I'm not a smart boy) But I think all of those factors considered, there would still be more leeway than just how much the spider silk can stretch.
@@reicalg3 I think his adherence is pretty OP. Not sure but i kind of remember him lifting heavy stuff from a wall, which is weird now that i think about it. He is stuck on the direct surface, but it can't be deep (Like the hairs coming from his fingers in the movies), so wouldn't the part he is walking on rip off the wall if he is lifting heavy stuff? Not like he is nailed 3 inches into the wall...
Aska Lon Spider-Man’s adhesion is ridiculous. I recommend this video if you want an idea of how powerful it is: ua-cam.com/video/PAh1SSgp5wo/v-deo.html
Aska Lon If Spider-Man was on the side of the pillar the maybe the bricks under his feet could come loose (although I doubt it) but if you look at the comic panel he’s standing on top of the pillar so that’s not a problem.
@10:56 lol thats exactly what Green Goblin says. He says the shock of falling off killed her and that "she was dead before she hit the ground" if Spidey hadn't caught her. Also it's implied that her neck snapped.
Am sure its been mentioned here somewhere that Uatu the Watcher confirmed (through one of Kyle's alternate universes) that Gwen could have been saved by Peter jumping to catch her in his arms rather than using the web line, wondering if that knowledge would give him peace or torment him further. So also canon that she died from the web, just as normally presumed, as always tho another fun and educational vid!
Hi, Kyle. I have been a long time fan of the show ever since your video on Quicksilver's Walkman. Your videos have allowed me to have a much better understanding of complex scientific concepts, especially as I have been working on my astrophysics degree. Now, I have a question regarding a What If? comic Marvel released recently. In "What If Peter Parker Became the Punisher?," the same incidents of "The Night Gwen Stacy Died" occur except Gwen survives. What happens differently is that Peter catches Gwen with a web line and swings her into a lift, where she lands in a web net. When Peter goes to check on her, she is alive and is alright after a few days in the hospital. My question is this: would Gwen still survive her fall in this situation? Would the web net supply enough time for her to be slowed down, or would the added torque from Peter's swing or some other force be enough that she would still die? Thank you for all you've done, and I look forward to more content in the future.
Hey Kyle! Love the show! What's more amazing is that spiders mainly use two types of webs. By varying the protein component, they also vary it's properties. They use a more rigid one composed of more beta sheets than alpha helices of protein, for support when they are hanging and for the radial structure of the web, on the other hand a more flexible web, with more alpha helices are used for the spiral part for capturing prey and wrapping them.
Hey Kyle (and by extension, the keepers of the void), what do you think about the idea of using webshooter-like technology as a tool for use in space? Like some sort of sticky, spidersilk rope like grapple to move around in weighless situations... It could aid in mobility in larger spaces and could potentially save lives during spacewalks. The web wouldn't need to be crazy strong to just pull around the mass of a human and their gear, nor would it need large amounts of propulsion since it doesn't have to fight against gravity or air resistance. It could be built into a space suit and the user could just aim and shoot at some chosen anchor point to pull or winch themselves in that direction. I sure there's a lot that would need to be worked out but I think the idea would be a lot easier to implement in those cases. Since it's a single string it'll be easy clean up and there's no needd to worry about pesky nanoparticles. This is mostly me just thinking about a few episodes I was rewatching and felt like combining some of the ideas in them. Seems a lot easier to accomplish for space than for terrestrial purposes. Who knows, maybe this comment can spark someone's imagination and we can find out of it's actually possible. Anyways love the show! I really like learning in such an entertaining way.
Pretty sure astronauts already use pretty lightweight ropes to tether themselves to the spacecraft on EVA missions. Also I have a feeling magnetic or bayonet connectors would be cheaper and more reliable than "sticky" rope. But I'm certainly not an expert.
Pyrrha Nikos not really talking about tethering. What I'm talking about is something like a tool for large area maneuverability. A tether (at least in my head) is something that's always connected, whereas this would be able to connect and disconnect. You're right, some sort of magnetic grapple would work too but not everything is magnetic so it would be more limited. Plus it would be safer to collide with the silk rather than a rope.
I think it would be interesting to calculate the force the Goblin Glider struck her with to launch her off the bridge, and if it was enough to have caused enough damage to make her susceptible to dying from something that was otherwise survivable.
Really funny coming back all this time later and hearing excited advertising for Fallout 76. Also cool video, poor peter can't even win when the odds are in his favor lol.
See, talking about the strength of Spider-Silk now you've got me thinking... the scene where Spiderman holds a BOAT together (or stops a train, any of these feets), just how much Spider-Web would he need to use, how does all that force transfer onto his arms/body? Would the webbing fail?... Man, really curious now.
Snap is the 4rth differential of position to dime. Acceleration is the second. Jerk is the third. Just put jerk in your comment and youll have a double joke
Hey Kyle, I just had a midterm where we had to justify how globular and fibrous proteins would affect the makeup of spider-silk for Spider-Man. It makes sense in the way that it can be used for web-swinging and capturing criminals, but how would it change based on the gadgets that he uses? Would taser webs have to have a different chemical makeup in order to make them more conductive? In the PS4 game when you use web bombs and impact webs, would they have to change slightly too, or is it simply that the mechanism that launches it determines the outcome?
Hey, Kyle. Love the show! Quick question: do you actually calculate all your equations yourself or are they (fully, mainly or partly) outsourced to other people, like a behind-the-acenes team?
The one thing I really liked about the Amazing Spider-Man 2 is that they had Gwen hit her head on the ground and that's why she died - because Spider-Man just barely couldn't save her.
Depending on how fast she decelerated, it is possible that she could still experience a blackout and possible brain damage from how she slowed down. In addition, depending on how she was caught, it could potentially cause damage to her joints (including dislocation) and to her muscles, ligaments, and tendons. So, she might have a significant limp or need a cast after being caught.
If you recreate the same panel the way they did in The Amazing Spiderman 2 would she still survive? I'm not sure she would. Peter had to stop her just before Gwen hit the ground and his silk didn't have any stretch at all. It didn't stretch in the Amazing Spiderman when he was saving cars thrown from the bridge. In almost all media comics, animated series, movies there doesn't seem to be a constant where Peter's webs stretch at all, only when the plot says it has to.
That was pretty much the basis of my question, too. If the webs were stretchy, some of the disasters wouldn't necessarily be averted. An out of control speeding car would still go 40% farther than the point it was hit with the web, slowing the car down, of course, but not stopping it right away either. Some of that energy could still do a lot of damage to people, places, and things before it stops. It seems to me that Spiderman's webbing acts more like a bungee cord than a rope.
@@XansStuff That's true, but that was organic webbing from his body. Spiderman uses web shooters on his wrists as you know. The organic webbing from Sam Raimi's trilogy would work just like real spider silk. The webshooters use a spider silk base but its not pure spider silk so its ability to stretch should be less.
@@ScottPhx That is true. But In how many comics, movies, cartoons, and games have you seen the sling shot maneuver? A sling shot doesn't work with rigid bands.
Assuming all of your assumptions are correct, what about a possible snapping movement of Gwen’s body when her body slows down and possibly whips her head? Just a thought for your footnotes.
Darn it!!! I commented right before you concluded your video but would still love for you to address the whipping motion of her body and the force exerted on her neck.
Hello Kyle love the show (and your hair). But there were a few things i noticed in the first couple minutes: 1. During the start when you were climbing on top of the void (which I’m struggling to figure out how) but when you moved you made weird noises which never happened for Spider-Man. 2. When you used your webs to get onto the left side of the bridge you could hear the familiar sound of the web being sent out of your hand, travelling to the top side of the bridge, and then finally you going there in a couple seconds. Due to the angel in which the webbing is joining the bridge we can assume your going up the side of the bridge with the webbing. If we assume that your on the bottom of the bridge than you’d be the fastest Spider-Man ever, which I would think be better if he was played as you. 3. Now later in the video you Spider-Maned over to the right side of the bridge in let’s say 2 seconds. That would mean my point before is confirmed as you’d be travelling ridiculous speeds 6570.0000 kmh (or 4082.4087 mph for you American boi) Or I could be overthinking this and you just wanted to edit yourself to be more like Spider-Man. With that Thor like hair of yours I would love to see you do it. I’d probably do some stuff for the chance to see Spider-Thor come in and save me or stop me. Anyway love the show and I hope you continue doing it.
Kyle has web powers! Oh my goodness an adgardian with freakin spider man powers! Spider thor, spider thor, does whatever spider thor does. Shoots a web, at the hulk, but mr. hulkey doesn’t really care. He gets smashed, off a plane, now he’s salty and quite mad. Thanooooos is gonna kill spiderrr thooor!
Peter Parker is very much a person who can't rely on luck to be on his side. It's a pretty common theme throughout most media starring him that if there is any probability involved it will play against him.
EVEN IF Gwen's deceleration is within "survivable" means doesn't mean she would just not die. even outside of "rotational forces" from her neck not being straight, she would still need immediate medical attention. the kind of medical attention that would require several surgeries. IF she did get immediate medical attention and didn't die, she would most likely be permanently crippled. the emotional trauma mixed with constant pain management and hospital bill stresses (not to mention possible development of permanent mental illnesses caused from the physical trauma) would be major receptors to create SI, and 45yrs ago none of this would be treated with the reverence it has today, so most likely she would take her own life. that's the worst of the best case scenario....but realistically, between where she fell and the events surrounding her death, she wouldn't receive immediate medical attention and die anyway. not from the fall or the way it's defined in the book. Kyle's math/science only prove it's SURVIVABLE....but you might as well say "chugging NY hot dog cart water is survivable"....if the water itself doesn't kill you, the hot dog cart owner will.
One piece I think you're missing in this is the webbing probably stretches as it leaves the web cartridges, which are (ostensibly) under pressure or being fed through pressurized nozzles. If it wasn't pressurized then it wouldn't be able to eject the distance it does, and there's the obvious benefits of a preloaded tension on webbing that would help move Spidey along or yank things towards him.
I love a good love interest death as much as the next bad guy, and I think you've oversimplified this to give her a chance, you do-gooder. Whilst she might have survived a simple drop if everything had stayed perfectly in line, a body on the end of a line of spider silk is going to work more like a compound pendulum, where any slight deviation away from the vertical would result in an acceleration when the line started to get taut. Her body, held at the ankle, could pivot at the knee, hip, along the spine and crucially at the neck, and with the human head weighing around 5kg that could make for some significant g forces experienced by the brain. So, if spiderman hadn't been directly above her, or she hadn't fallen vertically downwards in a perfectly straight dive, then I suspect she might have suffered like the end of a bullwhip does...
@Draugyr That also wasn't off the side of a bridge, it was in a clock tower. When Kyle mentions that she fell halfway down the bridge's height it's assuming that she's falling towards the water. This is important because if we subtract the clearance that the bridge allows boats which is roughly 41 meters (rounding down), we assume the same fall distance, and also assume that the height of the clearance from below is the exact same height of the road above. Then the Spider silk's stretchy slowing-down properties only have about a meter and a half to slow her fall before she hits the bridge. I believe that if that's the case then she'd die, something similar would happen if she fell almost to the water's level because the surface tension of the water would feel like hitting a solid surface, e.g. concrete, when you fall at certain speeds. If someone wants to calculate the maximum distance that she could fall off the side of the bridge, get slowed by the spider silk, hits the water, and then lives please go ahead. I don't want to do the calculations right now.
Hey there! Just a note here for you: Another analysis of this that I've seen, using some of the same points you brought up, also looked at the panels closely... and according to them, the Goblin-Bomb that detonated at her feet, blowing her off the bridge, is what actually killed her. Her neck snapping was just an after-effect of Spiderman catching her now limp, lifeless body, which would react differently than a living person
@@thomasgrinwis9384 lethality is possible but more likely that a blood vessel burst under the pressure and make problems possibly total mental disability or some such other things.
I think the most determative factor would be in how the web catches her. The way they showed it in ASM2 could definitely kill someone. But I don't see the old school ankle grab as being nearly as deadly. The neck just wouldn't be shocked in a way that has a high probability of causing permanent harm. The continuation of motion even with the stretchier webs. A grab from the waste could still cause deadly harm to the neck since the human body just isn't suited for harsh directional changes in the direction.
Air resistance would lower the speed. With these calculations Kyle showed that Gwen might have survived at this speed. So the logical assumption would be that she would also survive if the speed was lower. Worst case scenario kind of thing. And because it was easier this way 😉
Also, we need to take the weather into account, the temperature of the surrounding area to be precise. Spider silk becomes more rigid and brittle when the weather is colder, so the time of year this happened also needs to be considered when making the calculations, but that's a whole other set of mathmatical formulas that need to be calculated as well.
Love the show, mostly because of your hair 😅 Shouldn't the stretchiness and the toughness of the web be higher since it's not a single pencilwide strand Spiderman shoots out, but a multitude of strands adding up to a pencilwide "rope"?
The young modulus is a bulk property, which means that for a given stress applied to a material, despite any variations in the dimensions or volume of the material (approximating the material as a cylinder), the same strain should be produced As the thread used by spiderman was thicker than theorised; the cross-sectional area increases. Then assuming force of extension as a constant, the stress would decrease as stress is equal to force per unit area, therefore as the young modulus is assumed to be a constant the strain would also decrease. If the object only changed in thickness (not length) then this would result in a decrease in extention, as strain is equal to extention divided by length. This means that as the thread becomes thicker, the extention per unit force decreases, and thus the spring constant also decreases. This means that a pencil wide thread would be less stretchy.
I just realized, in the amazing spiderman movie, spiderman caught gwen stacy 2 times in the same way (at school and inside the clock tower), but only 1 time she survived, the other, well ....
I read a Spider-Man 30th anniversary comic that had a great take on this. Peter Parker said he wasn’t sure if he killed Gwen with his webs trying to save her or if the Goblin killed her beforehand and dropped her as a part of a mind game. The uncertainty was what drove Peter nuts. (Unfortunately, this seems to have been long forgotten). That explanation would fit well with the science and the story.
I wish you had explored what makes up Spider-Man's webs, it would have helped as a comparison to real spider silk. Also, how much does it take to snap a neck taking into account the downward momentum and whiplash?
I have heard many times the shock of the fall will kill you, before you hit the ground. The explanation I have found is that the shock of falling from a great height and realizing you have no way to stop yourself induces panic causing a heart attack.
The movie version if I am not mistaken had Gwen wrapped by the hip/low torso. There what kills you is not the whiplash, but your body flexing beyond what it should. This is why painters and high rise operators have full body harnesses.
The Amazing Spiderman 2 movie also seems to address this,as the stretchyness slows her fall... but its too little to late as her neck impacts the floor, breaking her neck that way instead.
Why does Thor crawl on the ceiling like Spider-Man?
Because science!

I think this gives one choice in The Amazing Spider-Man 2 some credibility. Instead of falling off of a bridge and having the chance to survive, she falls from the top of a clock tower and smacks her head on the ground. No amount of spider-silk stretchiness could have saved her in that scenario. So maybe the writers of that movie considered this when making that change!
Cameron Lightfoot, SM does catch her, but so late in the process that there wasn’t enough time to decelerate much. She even bounced back up (too much).
i think the writers wanted spider man to come out as the hero even if he wasn't able to save her
I actually loved that scene in the movie because the entire time your teased back and forth with are they actually going to kill her or not. They even make it look like they are going to go against the comics and actually have her live, then they snatch the rug out and give us an even more brutal end.
I still remember the theater starting to groan/cheer that he saved her to that loud thunk and the immediate silence of the audience.
But SM 3 (i know we don't talk about SM 3, no one should) her head is still snapped backwards and breaks her neck even as she was slowed down before stopping.
I thought she died in that movie from her spine snapping and I dont remember seeing her actually hit the ground. Guess I gotta comb UA-cam for answers now lol

@@becausescience you should do a video on the movie version of Gwen's death. I think it would be interesting🤷♂️
It's already obvious that she would die. Because the whiplash wouldn't kill her, but the unnslowed down force of her head hitting the concrete would. Being dumb, Andrew Garfield's Spider-Man aimed for her torso, when he really should've aimed for her chest.
If spider man did a safety net under her instead, maybe she would survive?

@@becausescience look forward to that 1, as soon as I saw it in the cinema I started thinking about it. Trouble is every time I think I'm done I spot another variable I missed. I would suggest doing a simplified version like you do sometimes.
Hey Kyle! You calculated Gwen as a single point of mass, but a falling body is far more complicated than that. You do mention it briefly further into the video, but the acceleration from rotation could actually increase the velocity of her brain case (think of a waterskier going faster than the boat when turning). This acceleration then deceleration would cause severe brain trauma. So how she's falling and where the web connects are vitally important.
I was thinking about this from the very beginning of the video. I don't even want to begin to try to calculate how far she could fall before there would be life-altering trauma to the brain.

Well there is a detail easy to miss that you miss in the panels. There are three panels of Gwen falling first of her upside down, second of her head upwards (her hair and hand are both visible facing up), and finally the one with the web on her leg of her facing down again. This might mean that she was spinning while in the air.Wouldn't this add a rotation? by pulling her leg upwards while her head is going downwards it increases the Gs that her neck and brain is suffering. I mean there is a reason why people try no to spin vertically while bungee jumping aside of a few broken ankles you risk to suffer a hypovolemic circulatory shock by all the blood rushing in a sec.
she would have to be tumbling at 31 rpm (assuming she is 6') to generate 1 g on her head.
and that would mean she was spinning at running speed, not likely.
so the tumbling wouldn't make much difference.
The sad part is Gwen Stacey is dead... but at least we know that of the different versions, the more realistic one was the one in which Gwen Stacey fell more than 42 meters.
Her head could have torqued back , depending on directionality of her rotation as opposed to the web's vector causing the skull to pull from the atlas vertabrae which in turn causes the medula oblongata to strike the base of the skull which causes it to swell which in turns stops autonamic nerve function leading to a coronary. Had spiderman given her CPR she would have survived. A strike to the base of the skull to cause thia if I remember correctly is about 3 psi.
@@scotthenderson4687 , @ruyman90 Come on now, you guys are just throwing out terms and conditions ; hypovolemic circulatory system shock? New to me. And Scott, you a biology major because medically it's normally called a herniated brain stem. Just curious...
Reckec I did not major in bio, but have taken a few medical related courses. I refer to the medulla oblongata which is a part of the brainstem that controls autonomic function of heart ,lungs, body temp regulation etc.. I also studied martial arts and as such reenforced my knowledge from A&P courses. And i used that knowledge to determine why she died instead of could she have survived. The injury I described is well documented in medical text. As results from auto crashes induced by heavy whiplash, as well as getting struck in the back of head.

@@JianCB2 pretty ugly is a bad example since pretty has more than one meaning. It can be used as a gradation such as pretty good or pretty bad.
@@Kmmlc Yeah, but my point stil stands.
Hi Kyle, i believe there are many additional factors to consider that would ultimately make the chances of gwen surviving much less likely.
first off we know spidermans's web slinging usually reach a wide variety of ranges to reach the different distances that he needs to traverse. this would mean spiderman would not only have to catch her with his web, but he also needs to stop shooting his web at the right moment so that the length of the web would stop extending at the right time to stop gwen's fall before she hit the ground.
So factoring the mental stress to catch her in the limited short time frame he has to work with and to not over extend his web after catching her, it could come to reason that spiderman may have undershot the required length of web to catch her, which would mean the web silk that he shot was already stretched close to its tensile limit when it caught her. This then reduces the amount of cushioning effect his web would have on reducing her fall speed.
We can also prove that spiderman's does shoot his webs with such force that they usually do hit the target close to the tensile limit of the web on a regular basis. *anytime he shoots at a high point while standing on the ground, the web shot would usually launches himself into the air to allow his trademark web swinging action across the city.
while i myself am not too sure on the calculations to figure out how much tensile strength is required from his webs to pull him up into the air with enough elastic force, but this does prove that spiderman's web threads do get launched and stretched prior to hitting his target on a regular basis, and if his catch immediately pulled back on gwen after catching her, that only amplifies the halting speed of her fall rather than safely slowing it with a cushioning effect.
TL:DR spiderman shoots his webs pre-stretched so the web pulls back on the fall rather than slowing it safely.
Elyrx understandable
Elryx how would one shoot something pre-stretched if there's almost no force being applied to it? Also, staying rigid would make a lot of things in the movies VERY GRUESOME
chingcongwong the third I worded the tldr badly, my assumption is that the Web stretches as it flies through the air and therefore is more inclined to pull backwards from the elasticity upon hitting the target, rather than catching Gwen with the precise amount web required so that it is has extra room to stretch and cushion her fall.
Edit: there's definitely force applied to the Web shot out, otherwise it would simply spill? below spider man like tap water when he shoots the web
So what you're saying is that Spider-Man would carefully have to solve "how do i shot web" in order to save her? Also even if Spider-Man perfectly calculated the length of web required for the calculation of the intercept path that it would have to take for its deployment velocity, a pencil-thick material of almost 42m moving quickly enough to intercept a freefalling Gwen would have its own energy to have to account for when it comes to the stretching that occurs after its mass joins with Gwen's, contributing to the stretching parameters it would be experiencing once the line hits its limit. What you're saying about Spider-Man's normal transportation webs assumes, after all, that the webs themselves deploy with enough velocity to stretch itself such that he would be snagging his anchorpoints with an elastic burden already applied to the line such that he can propel himself with them. THAT BEING SAID, however, how do we know that it's a consistent web that he's shooting? He's demonstrated already that he has several web-slinging techniques at his disposal, there's nothing that really dictates that this pre-stretch technique is what's being deployed here. And going beyond 6G isn't even a death sentence either, people experience instantaneous forces of hundreds of Gs in car crashes and survive, so there's room for play as well. It might very well be Gwen survives with recoverable injuries related to her deceleration, the margins are wide enough.
@@stuchly1 Hey joke's on you, what I just said was literally verified in the Live followup show XD The word you've forgotten to take into account is "instantaneous" forces, I'm not talking about dropping a couple tons of solid lead because that would crush you dead for a solid tenth of a second or so, which is a lot of time to take those forces on your body and a lot of total energy transferred that would have plenty of time to apply breaking stress on all sort of body parts. Do a little google, it's actually a really fascinating subject.
So, if Gwen were *pushed* off the top of a bridge, there'd be some lateral velocity too, right? She wouldn't be falling straight down, strictly speaking. So regardless of whether or not there was enough give in the spider silk to safely arrest her fall, if Spider Man was standing on the top of the tower of the bridge, Gwen would be slowly moving laterally away from him at the velocity of the initial shove. Therefore, when the spider-line catches her, all of her lateral movement would translate into gravitational potential energy, and she'd swing back into the side of the bridge, upside down, and probably head first. Probably not healthy.
Also, don't most of those bridges taper as they get taller? They have a big central base, and then occasionally step in as you get higher up? If one were falling off the bridge, and impacted one of those steps, especially if falling head first, it'd do some damage!
No. Air resistance would slow any lateral velocity very quickly.
So... Just no.
Damn thats true
Still significantly better than a death plunge into a river, broken bones heal, maybe she still does but it's better than doing nothing.
@@christianlang348 They are actually right, there would be some lateral movement and Spiderman wouldn't be directly above her which would create a pendulum effect on her when the web-strand reached it's maximum length which could swing her into the bridge supports. Air resistance doesn't really come into play.
So ... Just no.
There would be a lot of air resistance cause by the act of covering a large distance quickly, vertically.
Any lateral movement would be dissipated very quickly after falling by the large amount of air on the way down. With no air, yes, they would move more, but factoring in air friction and aerodynamics, not so much.
So again, no.

@@chasenicotre8853 It isn't NOT cannon as well.
Nice analysis, Kyle. But, there is one factor you didn't consider. The spider silk has to attach to her body strongly enough to arrest her motion. Even if you assume Ol' Spidey has invented a quick-drying adhesive strong enough to support a human's weight (he does swing from his webs all the time, so I think that's a fair assumption), the web is only attached to a very small section of Gwen Stacey's skin. According to a study by Gallagher et al (see reference below), the mean dynamic tensile failure strain of human skin is 25.45 MPa, plus or minus 5.07 per cent. If we assume Peter Parker's web is attached to a one centimetre square area of Gwen's skin - and because 1 mega Pascal is equal to 1 Newton per square millimetre - Gwen's skin needs to be subjected to less than 2,545 N of force, or it would likely just be torn by the web. Since our hypothetical Gwen has a mass of 50 kg, and is falling at 29 m/s, she has a kinetic energy of 21,025 J at the moment the web contacts her. Unless I've completely messed up the math (which is quite possible, high school physics was a LONG time ago), Gwen would have to decelerate over a distance of more than 8.26m (say 8.5m to be safe) to keep the pressure on her skin below the tearing threshold. I think that would actually work, given how much some spider silks can stretch, but it's something that is worth considering. Cheers. EDIT: Put another way, at much above 5g of deceleration, Gwen's skin would fail before the web did. And if Peter liked his webs thin or his girlfriends thicc, she'd be in real trouble ;)

She would be wearing pants and boots. Which would either tear or be ripped off her. While spider man’s web slowed her down
Caio L Gon In the original comic she is clearly shown wearing boots and a dress. The web attaches to her bare skin.
@Arthur Williams
on the drawing it is shown as 5 strands , like a ribbon with bits going sideways like a mesh , but may actually be a mesh tube so it would have better grip but also less springiness , if it was a bridge over a river she maybe would have been better going into the water , also the web looks like its wrapped around her leg so it would hold :-)
YTANDY100 Yeah, I was taking a look at the original illustration again and it is hard to guess the total surface area of the web in contact with her skin. But with it wrapped around her leg, as it does appear to show in one panel, it would have a pretty substantial amount of contact. If each of those strands is 1 mm wide, and her ankle is 200-250 mm in circumference (around 280 mm is average for American women today, but Gwen is slim), then we’re talking 10 to 12.5 cm2 in contact area, dropping the force on her leg well below the skin tearing threshold. It would probably hurt to be stopped that way, but as long as the web is stretchy enough it would work and she’d survive.
1:02 he clearly covers more than a square centimeter of her leg in webs. Seems like you're using the scene in the movie and not the comic book scene.
Great video, Kyle. My wife and I love your show and I especially love your Spider-Man centric ones. Couple of things though; I know you based your calculations off of real spider silk, but Peter is constantly updating, changing, and making new variations on his basic webbing formula. It’s possible he had something with less elasticity at the time. Also I know it’s hard to tell because it’s from a comic book page, but do your calculations take into account the possibility that in a panic maybe Peter pulled up on the webbing as it caught Gwen? He does have superhuman strength and it’s been documented time and again that he holds back. So in a panic, maybe he pulled up on the web just a little too hard, reducing the cushion the web would have given Gwen during her fall. This is the love of his life, so him being a little overzealous would be plausible.
NobiZero exactly my thoughts
So much math! lol. Bad batch of spider silk, made by spider man.
Courtney Dalton that too. Peter is human. He makes mistakes.
Often.
Finally another theoretical situation that does not make use of some other Scientific principle
I've always wondered, how much "web fluid" can the small canisters in his web shooters really hold? They're small and he shoots a LOT of webbing before he runs out. Also, it's not the fall that kills you, it's the sudden stop.
bungee jumpers fall and are arrested by bungee in a similar fashion.
Judging by the comic frames, there looks to be only one ledge that between her and the water in the catch frame, being that the tower gets wider, she must have had some horizontal velocity leaving the top. Now, without me adding more math to this, i will add a few thoughts. spiderman was at the top when he caught gwen, who was in your video halfway down. at that point (approximately) the tower gets larger. Accounting for the horizontal velocity and spiderman being closer to center than her, when arrested she would have flung into the tower. Kyle, you rock climb so im sure you are aware that its not fun to fall and then swing into the object you fell off of because your lifeline is attached to it. Gwen fell head first so i assume there was some blunt force trauma between her head whiping under her pivot point and the side of the tower.
that leaves worse imagery than the comic... possibly why it wasn’t included.
RockoSpaz86 bungee jumper has a ankle grip surrounding both feet. I don’t think the spider web would surround her foot. Also usually Spider-Man’s web usually is shown sticking to a Surface. Which means sticking to shoes, boots and pants. That could be pulled off when the web stretched. So she would fell pant less after smashing the bridge.
@@CaioLGon Apparently she was wearing a dress and it did attach to her bare skin, and it did wrap around her leg according to another comment on here.
Hey Kyle, cool episode. Gwen was the best and I would have loved for the scientific outcome to have been canon.
Two things that might explain why she does die are
1 Like you said, she may have fallen at an angle. In the comics you showed, she seemed to be falling horizontally. So if spiderman caught her by her legs, her body would have started rotating, which could (mind the word 'could'; I'm not sure) have caused a whip-like effect that would snap her neck, literally cracking it like a whip.
2. If spiderman caught her below 28% of the height of the bridge (so the stretch length remaining would be less than 40%) She could have simply hit the floor below. Then the spider silk would have helped her stay perfectly vertical, so that her head would be the first thing to hit the floor.
Kyle, we’re gonna have to agree to disagree. In the iconic panel, we can see that Gwen is arched and her head is snapping backwards. I think given the visual evidence given, we have to assume she pivoted on her heel once Spidey caught her. Using your numbies, a radius of 1.57 m (via your used wt and the Hamwi formula), and the centripetal acceleration formula of F = m * v^2 /r, the slowest F I can get is 9642 N applied to her cervical vertebrae. From my research, it takes ~ 4400-5600 N to fracture the cervical spinal column. Poor Gwen is still doomed.
Make videos. We need your knowledge.
I.E. a weird angle, exactly as Kyle (?) mentioned. He never said Gwen was guaranteed to survive, just that, given the information Spidey was working with, the solution that was attempted could well have worked.
I think the writers of The Amazing Spider Man 2 figured out that the math was just as you said Kyle and there for made it so Gwen's head hit the ground. But you know in comic books nothing has to make sense for it to be entertaining or tragic. Great work and love the vids.
In the beginning you mentioned whip lash. This usually causes injury in apegdages such as a neck, by first accelerating the appendage (in this case a head attached to a neck) parallel to the velocity vector, followed very quickly by the neck accelerating in an arc perpendicular to the velocity vector, thus the neck quickly dislodged and causes "the injury." She might die by being swung in a weird way even if she fell a smaller distance.
Edit: Kyle mentioned this case at the end of the video. Opened my damn mouth too early.
happens to me all the time, I don't want to lose a thought while I'm watching a vid so I pause and type a comment.
Hahaha A LOT OF PEOPLE NOT WATCHING THE WHOLE VIDEO IN THESE COMMENTS -- kH
You can type it and wait for the video to end before posting it. This way if you think of any further comments you can post them within the same comment without the need to edit it.

A classic in the making
Hey Kyle awesome episode. I think it’s ironic that you proved the stretch of the web would have saved her during the fall in the comics but the stretch of the web was a factor in what killed her in the Amazing Spider-Man 2 movie. Thanks for another great episode, keep on keeping on.
In comic Captain Stacy died when Spider-man fight Doctor Octopus and in movie it was when he was fight The Lizard, also Norman Osborn Green Goblin killed her in comics and in movie it was Harry Osborn.
In the movie, her head hits the floor because he was a second too late
Negative. In ASM2 she suffers whiplash due to a sudden stop from a tense web. She never hits the ground.
thing is, spider-man's web properties and formula evolved with his experiences. It's not real spider silk, but an analogue. The death of Gwen stablished that his early webs were calibrated on strenght and elasticity more with spider-man and his villains in mind than regular people, and spidey is at least a couple orders of magnitude stronger and more resilient than gwen. And he knew this. But when Gwen was falling erred in panic and shot a regular webline instead of going for safer options. That's the core of his Gwen guilt, he got clouded in emotions in a life or death situation and he fucked up tragically. Since then most of the times he tries to push away allies and friends that could help him in his fights, because he doesn't want to put them and himself in a compromised situation again.
Is this canon? Because that would be very sciencey -- kH
@@becausescience It is, but a little subtle (sprinkled here and there in the 1000ish issues ever since). Since then, everytime he has come across a similar scenario (a loved one falling off some tall structure) it's common to portray him getting a little ptsd episode in his head and as a result applying safer methods to stop their fall (jumping after them and shooting an appropiate line using his own body as extra buffer, web air cushions, extra elastic web beds, shooting fine elastic lines to several points in the falling body to spread the forces better, etc.
I remember reading about when Gwen died when I was a kid. I always thought that she died from fear, not from the sudden stop that snapped her neck. How odd.
Two major factors could have an impact here, one being a hypothetical, the other a canon fact.
One canon fact about the original Peter Parker, he made his own webbing and shooter, creating the fluid that would react to the air and harden into his iconic webbing as he shot it out. So its plausible that his mixture has more rigidity than standard spider silk. Another point in favor of this possibility is the way his web seems to maintain length as he swings, rather than show signs of stretching during the arc of his swing due to momentum. Feats mirrored in newer media, showing the lack of elasticity, though there are exceptions.
-Anything involving a train comes to mind.
Though there are some free fall moments too, but those are a mixed bag. Some are sudden stops, others are slowed descents.
But it could point to the fact that her falling did not carry enough energy to counter the rigidity of his webbing, given how much thicker it is compared to spider silk, and he made it with his weight and velocity during a swing in mind initially.
He has also changed the composition of his webbing for various situations, so its consistency varied quite frequently, and may not have been suitable for that situation.
For the hypothetical- I have heard of a medical condition/birth defect that could play a part in this to deadly effect. Weakened vertebrae of the neck and spine that left the individual more susceptible to trauma due to sudden jerks and concussions, or blunt impact to the back of the skull. Which could result in spinal damage that would leave one partially, or completely numb below the neck, followed soon by death. Such a person would be at a high risk of injury and likely be warned off bungie jumping, high diving, kidnapping by hobgoblins, and roller coasters.
Keep in mind that Spidey's webs weren't like actual webbing. They had settings based on his pressure on the button. He could have easily made it more rigid or other without realizing it.
10:36 Hey, I understood that reference!
I didnt. There's a reference? Captain?
Its a spiderman meme where two spidermans are pointing at each other
Additionally what the comic doesn't calculate for is the potential dissipation of Gwen's kinetic energy if the web was fired at an angle. This would give an additional decrease to her velocity as she swings in an arc reducing the need for a strong flex to web.
Hi Kyle! I Love the show! And I love the hair! 🙂
James Kakalios in The Physics of Superheroes points out an even bigger basic misunderstanding flaw.
Where Spider-Man receives a harsh physics lesson, and the Green Goblin’s scientific “genius” is called into question.
At the last possible instant, Spider-Man manages to catch Gwen in his webbing, narrowly preventing her from plummeting into the river below. And yet, upon reeling her back up to the top of the bridge, Spider-Man is shocked to discover that Gwen is in fact dead, despite his last-second catch.
“She was dead before your webbing reached her!” the Goblin taunts. “A fall from that height would kill anyone-before they struck the ground!” Apparently the Green Goblin, creator of such advanced technology as the Goblin-Glider and Pumpkin Bombs, suffers from a basic misunderstanding of the principle of conservation of momentum.
Of course, if it were true that it was “the fall” that killed poor Gwen, then the implication for the fate of all skydivers and paratroopers would suggest a massive conspiracy of silence on the part of the aviation industry.
EDIT: Kyle mentioned this at the very end of the episode...
Well, still first like and comment. :)
How?
Because Science! :)
BE PREPARED FOR FOOTNOTES WHERE THIS ABSOLUTE LEGEND WILL GAIN THE TITLE OF: NERDIEST GUY!!!(or whatever ya want to call it)

With so much real science and research poured into these videos, it really makes my favorite comics feel more alive. Keep it up dude 🤙
Hey Kyle
Great episode, as always.
Question, we covered the whether the web snagging Gwen would have killed her. But what about Gwen's position in the air? She was head pointed down like a dive, what if she was falling chest first like a skydiver slowing their fall? Or if she was falling back first facing up at the top of the bridge? Would the pendulum like snap of her swinging have done the damage necessary to kill her?
Take Care and Be Well
the problem is that whenever the back of the head hits any object with enough force that blood comes out the nose(like what happened to lovely gwen) to much internal damage, the person is gone “unless an ER is within minutes to remove the back of the skull for swelling” then it is still iffy... emma did such an amazing job of making gwen perfect.. it is the ONLY death scene in any movie that made tears go down my cheek.. i still have a hard time watching it
You are not lying. Just saw that particular Spiderman movie for the first time a few days ago, and it affected me emotionally more than I expected. They had a great chemistry and the movie did a really good job of making you care.
Spiderman body would also have some give, being pulled by Gwen's bodyweight. He is strong enough to lift tons but he doesn't have an incredible weight (although his surface adherence might somewhat negate my assumption )
Glad I came through the comments. I was thinking about this as well. I think it would be pretty hard, but not impossible to math out. We need his weight, how well he adheres to the surface, his strength, and his body posture. (I'm not a smart boy) But I think all of those factors considered, there would still be more leeway than just how much the spider silk can stretch.
@@reicalg3 I think his adherence is pretty OP.
Not sure but i kind of remember him lifting heavy stuff from a wall, which is weird now that i think about it.
He is stuck on the direct surface, but it can't be deep (Like the hairs coming from his fingers in the movies), so wouldn't the part he is walking on rip off the wall if he is lifting heavy stuff?
Not like he is nailed 3 inches into the wall...
Aska Lon Spider-Man’s adhesion is ridiculous. I recommend this video if you want an idea of how powerful it is: ua-cam.com/video/PAh1SSgp5wo/v-deo.html
@@jk844100 Yeah i know, i just mean that the surface below his soles would rip/break, like mud would stuck to the bottom of your shoes...
Aska Lon If Spider-Man was on the side of the pillar the maybe the bricks under his feet could come loose (although I doubt it) but if you look at the comic panel he’s standing on top of the pillar so that’s not a problem.
@10:56 lol thats exactly what Green Goblin says. He says the shock of falling off killed her and that "she was dead before she hit the ground" if Spidey hadn't caught her. Also it's implied that her neck snapped.
Hey Kyle, how powerful are the arm pistons on Big O?
I wonder the same thing
Am sure its been mentioned here somewhere that Uatu the Watcher confirmed (through one of Kyle's alternate universes) that Gwen could have been saved by Peter jumping to catch her in his arms rather than using the web line, wondering if that knowledge would give him peace or torment him further. So also canon that she died from the web, just as normally presumed, as always tho another fun and educational vid!
Hi, Kyle. I have been a long time fan of the show ever since your video on Quicksilver's Walkman. Your videos have allowed me to have a much better understanding of complex scientific concepts, especially as I have been working on my astrophysics degree.
Now, I have a question regarding a What If? comic Marvel released recently. In "What If Peter Parker Became the Punisher?," the same incidents of "The Night Gwen Stacy Died" occur except Gwen survives. What happens differently is that Peter catches Gwen with a web line and swings her into a lift, where she lands in a web net. When Peter goes to check on her, she is alive and is alright after a few days in the hospital. My question is this: would Gwen still survive her fall in this situation? Would the web net supply enough time for her to be slowed down, or would the added torque from Peter's swing or some other force be enough that she would still die?
Thank you for all you've done, and I look forward to more content in the future.
Hey Kyle! Love the show!
What's more amazing is that spiders mainly use two types of webs.
By varying the protein component, they also vary it's properties.
They use a more rigid one composed of more beta sheets than alpha helices of protein, for support when they are hanging and for the radial structure of the web, on the other hand a more flexible web, with more alpha helices are used for the spiral part for capturing prey and wrapping them.
Hey Kyle (and by extension, the keepers of the void), what do you think about the idea of using webshooter-like technology as a tool for use in space? Like some sort of sticky, spidersilk rope like grapple to move around in weighless situations... It could aid in mobility in larger spaces and could potentially save lives during spacewalks. The web wouldn't need to be crazy strong to just pull around the mass of a human and their gear, nor would it need large amounts of propulsion since it doesn't have to fight against gravity or air resistance. It could be built into a space suit and the user could just aim and shoot at some chosen anchor point to pull or winch themselves in that direction. I sure there's a lot that would need to be worked out but I think the idea would be a lot easier to implement in those cases. Since it's a single string it'll be easy clean up and there's no needd to worry about pesky nanoparticles. This is mostly me just thinking about a few episodes I was rewatching and felt like combining some of the ideas in them. Seems a lot easier to accomplish for space than for terrestrial purposes. Who knows, maybe this comment can spark someone's imagination and we can find out of it's actually possible. Anyways love the show! I really like learning in such an entertaining way.
Pretty sure astronauts already use pretty lightweight ropes to tether themselves to the spacecraft on EVA missions. Also I have a feeling magnetic or bayonet connectors would be cheaper and more reliable than "sticky" rope. But I'm certainly not an expert.
Pyrrha Nikos not really talking about tethering. What I'm talking about is something like a tool for large area maneuverability. A tether (at least in my head) is something that's always connected, whereas this would be able to connect and disconnect. You're right, some sort of magnetic grapple would work too but not everything is magnetic so it would be more limited. Plus it would be safer to collide with the silk rather than a rope.
I think it would be interesting to calculate the force the Goblin Glider struck her with to launch her off the bridge, and if it was enough to have caused enough damage to make her susceptible to dying from something that was otherwise survivable.
A full analysis of the death of Gwen Stacy and the saddest part.... The fallout 76 plug in the beginning.
Really funny coming back all this time later and hearing excited advertising for Fallout 76.
Also cool video, poor peter can't even win when the odds are in his favor lol.
See, talking about the strength of Spider-Silk now you've got me thinking... the scene where Spiderman holds a BOAT together (or stops a train, any of these feets), just how much Spider-Web would he need to use, how does all that force transfer onto his arms/body? Would the webbing fail?... Man, really curious now.
Spiderman's silk couldn't stretch that much because if it did, Peter would face plant into the ground any time he swung from a low building
I would have a *neck* of a time surviving that *Snap*
Ew.
Snap is the 4rth differential of position to dime. Acceleration is the second. Jerk is the third. Just put jerk in your comment and youll have a double joke
That is uniquely terrible. Have a like.
Hey Kyle, I just had a midterm where we had to justify how globular and fibrous proteins would affect the makeup of spider-silk for Spider-Man. It makes sense in the way that it can be used for web-swinging and capturing criminals, but how would it change based on the gadgets that he uses? Would taser webs have to have a different chemical makeup in order to make them more conductive? In the PS4 game when you use web bombs and impact webs, would they have to change slightly too, or is it simply that the mechanism that launches it determines the outcome?
Hey, Kyle. Love the show!
Quick question: do you actually calculate all your equations yourself or are they (fully, mainly or partly) outsourced to other people, like a behind-the-acenes team?
Its just sum math , pretty sure he does this by himself
The one thing I really liked about the Amazing Spider-Man 2 is that they had Gwen hit her head on the ground and that's why she died - because Spider-Man just barely couldn't save her.
When did thor became so smart?
Depending on how fast she decelerated, it is possible that she could still experience a blackout and possible brain damage from how she slowed down. In addition, depending on how she was caught, it could potentially cause damage to her joints (including dislocation) and to her muscles, ligaments, and tendons. So, she might have a significant limp or need a cast after being caught.
If you recreate the same panel the way they did in The Amazing Spiderman 2 would she still survive? I'm not sure she would. Peter had to stop her just before Gwen hit the ground and his silk didn't have any stretch at all. It didn't stretch in the Amazing Spiderman when he was saving cars thrown from the bridge. In almost all media comics, animated series, movies there doesn't seem to be a constant where Peter's webs stretch at all, only when the plot says it has to.
Actually, in the Tom Holland Spiderman movies, it does. Like the Captain America vs Spiderman fight in Civil War.
That was pretty much the basis of my question, too. If the webs were stretchy, some of the disasters wouldn't necessarily be averted. An out of control speeding car would still go 40% farther than the point it was hit with the web, slowing the car down, of course, but not stopping it right away either. Some of that energy could still do a lot of damage to people, places, and things before it stops. It seems to me that Spiderman's webbing acts more like a bungee cord than a rope.
Comic panels ar static images never se the vibrations. Plus if you remember the Train scene in Spiderman 2 you can see the web stretches quite a lot.
@@XansStuff That's true, but that was organic webbing from his body. Spiderman uses web shooters on his wrists as you know. The organic webbing from Sam Raimi's trilogy would work just like real spider silk. The webshooters use a spider silk base but its not pure spider silk so its ability to stretch should be less.
@@ScottPhx That is true. But In how many comics, movies, cartoons, and games have you seen the sling shot maneuver? A sling shot doesn't work with rigid bands.
0:11 that sounds so wrong on so many levels xD I assumed the sound would be closer to velcro being ripped apart quietly :P
Assuming all of your assumptions are correct, what about a possible snapping movement of Gwen’s body when her body slows down and possibly whips her head? Just a thought for your footnotes.
Darn it!!! I commented right before you concluded your video but would still love for you to address the whipping motion of her body and the force exerted on her neck.
Hello Kyle love the show (and your hair). But there were a few things i noticed in the first couple minutes:
1. During the start when you were climbing on top of the void (which I’m struggling to figure out how) but when you moved you made weird noises which never happened for Spider-Man.
2. When you used your webs to get onto the left side of the bridge you could hear the familiar sound of the web being sent out of your hand, travelling to the top side of the bridge, and then finally you going there in a couple seconds. Due to the angel in which the webbing is joining the bridge we can assume your going up the side of the bridge with the webbing. If we assume that your on the bottom of the bridge than you’d be the fastest Spider-Man ever, which I would think be better if he was played as you.
3. Now later in the video you Spider-Maned over to the right side of the bridge in let’s say 2 seconds. That would mean my point before is confirmed as you’d be travelling ridiculous speeds 6570.0000 kmh (or 4082.4087 mph for you American boi)
Or I could be overthinking this and you just wanted to edit yourself to be more like Spider-Man. With that Thor like hair of yours I would love to see you do it. I’d probably do some stuff for the chance to see Spider-Thor come in and save me or stop me.
Anyway love the show and I hope you continue doing it.
Kyle has web powers! Oh my goodness an adgardian with freakin spider man powers! Spider thor, spider thor, does whatever spider thor does. Shoots a web, at the hulk, but mr. hulkey doesn’t really care. He gets smashed, off a plane, now he’s salty and quite mad. Thanooooos is gonna kill spiderrr thooor!
I read this while rhyming the spiderman song, and it fits perfectly.
I’m taking AP Physics and AP Calculus this year and am now appreciating the work out into these calculations.
this is why in The Amazing Spider-Man 2 the spiderweb stretched and Gwen hit her head off the ground!
The head would be totally destroyed
6:01 you can see that when Spiderman stops a runaway train using is webs, the web stretches before stopping the train.
You look pertty sad whenever you mention Gwen's death. Did that moment in the comic have a real impact on you?
I got Gwen Stacy and Gwen Stefani mixed of for a second and was very worried
Peter Parker is very much a person who can't rely on luck to be on his side. It's a pretty common theme throughout most media starring him that if there is any probability involved it will play against him.
For his sake, I hope he never has to go up against Domino.
He spent too much time around Black Cat?
EVEN IF Gwen's deceleration is within "survivable" means doesn't mean she would just not die. even outside of "rotational forces" from her neck not being straight, she would still need immediate medical attention. the kind of medical attention that would require several surgeries. IF she did get immediate medical attention and didn't die, she would most likely be permanently crippled. the emotional trauma mixed with constant pain management and hospital bill stresses (not to mention possible development of permanent mental illnesses caused from the physical trauma) would be major receptors to create SI, and 45yrs ago none of this would be treated with the reverence it has today, so most likely she would take her own life.
that's the worst of the best case scenario....but realistically, between where she fell and the events surrounding her death, she wouldn't receive immediate medical attention and die anyway. not from the fall or the way it's defined in the book.
Kyle's math/science only prove it's SURVIVABLE....but you might as well say "chugging NY hot dog cart water is survivable"....if the water itself doesn't kill you, the hot dog cart owner will.
Well at least in the movie they get around this by having her head hit the ground.
I don't think her head actually hit the ground.
David Britt it did. I put it in slow mo. And that’s also why her nose was bleeding. ua-cam.com/video/Xi3P8vUveVQ/v-deo.html
@@superskullmaster Ugh, that crunch noise was so spot on too.
Kiyomasa The Crow sure was
Lol
One piece I think you're missing in this is the webbing probably stretches as it leaves the web cartridges, which are (ostensibly) under pressure or being fed through pressurized nozzles. If it wasn't pressurized then it wouldn't be able to eject the distance it does, and there's the obvious benefits of a preloaded tension on webbing that would help move Spidey along or yank things towards him.
I love a good love interest death as much as the next bad guy, and I think you've oversimplified this to give her a chance, you do-gooder. Whilst she might have survived a simple drop if everything had stayed perfectly in line, a body on the end of a line of spider silk is going to work more like a compound pendulum, where any slight deviation away from the vertical would result in an acceleration when the line started to get taut. Her body, held at the ankle, could pivot at the knee, hip, along the spine and crucially at the neck, and with the human head weighing around 5kg that could make for some significant g forces experienced by the brain. So, if spiderman hadn't been directly above her, or she hadn't fallen vertically downwards in a perfectly straight dive, then I suspect she might have suffered like the end of a bullwhip does...
Did you know that Spider Silk costs $340 per/gram .
In the Amazing Spider-man 2 her head hits the ground so we'll just meet half way
no it doesnt
MusicalBoarder I just watched it and the only thing that doesn’t hit the ground is her midsection, her head and feet both smack the ground
@@MusicalBoarder her head without a doubt hits the ground. Watch closely.
@Draugyr That also wasn't off the side of a bridge, it was in a clock tower. When Kyle mentions that she fell halfway down the bridge's height it's assuming that she's falling towards the water. This is important because if we subtract the clearance that the bridge allows boats which is roughly 41 meters (rounding down), we assume the same fall distance, and also assume that the height of the clearance from below is the exact same height of the road above. Then the Spider silk's stretchy slowing-down properties only have about a meter and a half to slow her fall before she hits the bridge. I believe that if that's the case then she'd die, something similar would happen if she fell almost to the water's level because the surface tension of the water would feel like hitting a solid surface, e.g. concrete, when you fall at certain speeds.
If someone wants to calculate the maximum distance that she could fall off the side of the bridge, get slowed by the spider silk, hits the water, and then lives please go ahead. I don't want to do the calculations right now.
we dont talk about the Amazing Spider-Man 2
Hey there!
Just a note here for you: Another analysis of this that I've seen, using some of the same points you brought up, also looked at the panels closely... and according to them, the Goblin-Bomb that detonated at her feet, blowing her off the bridge, is what actually killed her. Her neck snapping was just an after-effect of Spiderman catching her now limp, lifeless body, which would react differently than a living person
Kyle it may not have broken her neck but ... what about the blood in her body being that quickly forced I to her head what might that have done?
Possible make her faint. Maybe give her a little headache. Such things aren't lethal as far as I know.
@@thomasgrinwis9384 lethality is possible but more likely that a blood vessel burst under the pressure and make problems possibly total mental disability or some such other things.
@@shannonnezul4903 That is possible but with this fall and tbe catchting I believe this not being the case
I think the most determative factor would be in how the web catches her. The way they showed it in ASM2 could definitely kill someone. But I don't see the old school ankle grab as being nearly as deadly. The neck just wouldn't be shocked in a way that has a high probability of causing permanent harm.
The continuation of motion even with the stretchier webs. A grab from the waste could still cause deadly harm to the neck since the human body just isn't suited for harsh directional changes in the direction.
Why did you ignore the air resistance?
At these speeds it just isn't relevant
Air resistance would lower the speed. With these calculations Kyle showed that Gwen might have survived at this speed. So the logical assumption would be that she would also survive if the speed was lower.
Worst case scenario kind of thing. And because it was easier this way 😉
Without air resistance is worst case, because she's have a lower final velocity -- kH
@@becausescience hmmm that lower case K should mean something. 🤔
@@aliozanerbektas Started doing it because it reminds me of "pH" and I like it idk -- kH
Spider-silk is special, and so is Gwen Stacey....... Awwwwww lol
Also, we need to take the weather into account, the temperature of the surrounding area to be precise. Spider silk becomes more rigid and brittle when the weather is colder, so the time of year this happened also needs to be considered when making the calculations, but that's a whole other set of mathmatical formulas that need to be calculated as well.
Love the show, mostly because of your hair 😅 Shouldn't the stretchiness and the toughness of the web be higher since it's not a single pencilwide strand Spiderman shoots out, but a multitude of strands adding up to a pencilwide "rope"?
The young modulus is a bulk property, which means that for a given stress applied to a material, despite any variations in the dimensions or volume of the material (approximating the material as a cylinder), the same strain should be produced
As the thread used by spiderman was thicker than theorised; the cross-sectional area increases. Then assuming force of extension as a constant, the stress would decrease as stress is equal to force per unit area, therefore as the young modulus is assumed to be a constant the strain would also decrease. If the object only changed in thickness (not length) then this would result in a decrease in extention, as strain is equal to extention divided by length.
This means that as the thread becomes thicker, the extention per unit force decreases, and thus the spring constant also decreases.
This means that a pencil wide thread would be less stretchy.
Dosent spider man have magic silk as he is a mutation
I just realized, in the amazing spiderman movie, spiderman caught gwen stacy 2 times in the same way (at school and inside the clock tower), but only 1 time she survived, the other, well ....
Hey Kyle, love the show! Question: Would Peter's homemade web fluid work in the same way as biologically produced spider silk?
I read a Spider-Man 30th anniversary comic that had a great take on this. Peter Parker said he wasn’t sure if he killed Gwen with his webs trying to save her or if the Goblin killed her beforehand and dropped her as a part of a mind game. The uncertainty was what drove Peter nuts. (Unfortunately, this seems to have been long forgotten). That explanation would fit well with the science and the story.
Kyle I got nothing on this one but I guess I could SLING something up as this is the WEB after all. 😉😉
I think you meant to say TWHIP something up.
I wish you had explored what makes up Spider-Man's webs, it would have helped as a comparison to real spider silk. Also, how much does it take to snap a neck taking into account the downward momentum and whiplash?

When november finally ends
Kyle's observations are incorrect. Peter was using his old formula which was much more rigid than regular spider silk. He has since adjusted it.
Dear Kyle
Would the circumstance where the web had already stretched to reach Gwen affect her survival?
P.S. love your videos
I have heard many times the shock of the fall will kill you, before you hit the ground. The explanation I have found is that the shock of falling from a great height and realizing you have no way to stop yourself induces panic causing a heart attack.
I liked this video simply because of the J Jonah reference. Hahaha very nice. 👍
The movie version if I am not mistaken had Gwen wrapped by the hip/low torso. There what kills you is not the whiplash, but your body flexing beyond what it should. This is why painters and high rise operators have full body harnesses.
That's the kind of video that you just pretend you understood
The Amazing Spiderman 2 movie also seems to address this,as the stretchyness slows her fall... but its too little to late as her neck impacts the floor, breaking her neck that way instead.
