Supergirl, Martian Manhunter, Flash and more should all be able to lift Superman's key.

[@kalathedino1506]

Wouldn't 9000kg key still be quite safe. Such small edge inside stone would be really hard to move. Even with machines that can lift more than 9000kg. Also superman doing a guy thing with numbers makes sure noone really knows what they would need to move the key. What machine would you use to grab a tiny 9000kg key from stone and accurately manipulate it into keyhole.

[@anthonydavidson6139]

Not to mention that if his key was that heavy and that small of an object, it would just fall in a key shaped hole once he sat it down

[@anthonydavidson6139]

You know what? Go ahead and make a key that weighs 25 lbs and try to pick it up. I bet it would be crazy hard. First your fingernail would have to wedge under it and then you have to pick it up with only your nail in order to get your finger under it. Don’t think it would be hard? Go ahead and grab a 25 lb weight from the gym and pick it up with your fingernails

[@DrAthul1994]

I think I have another way ..... Well it's quiet simple ... The key is kept under the doormat on the ground right? So why couldn't u use some clay to take the imprint of the key and make another spare key from normal metal?...... Hope you read this Kyle ....

[@philipcollier4883]

Maybe Superman is lightly trolling Lois and its just a regular steel key but he places it on a super magnet.

[@longline]

Great episode Kyle. If (as Philip suggested) superman is trolling Lois and actually running an electromagnet on a steel key, we can do numbers on the magnet strength needed. Assuming your key is around 2mm thick, I take it the surface area was 4.5 cm2, or 0.00045 m2. The High Field Lab's 100 tesla magnet is powered by a 1200 megajoule generator, and that would produce around 1.79 million newtons on your key's area, or lift 182703 kg. That's big, but not big enough. Superman would need a 5275 tesla magnet to get the 4.9 billion newtons he's describing. A fridge magnet is 0.01 tesla. I did use an online calculator for this F = (D^2 × A) ÷ (8π × 10^-7), where D is the magnetic flux, and A is the area, but I'm still hoping I can get points for initiative.

[@blarghmcblarghson1903]

If it were a regular steel key being held down by a super magnet, wouldn't it deform or even break when Superman picked it up? He's not applying equal force across the entire surface of the key when lifting it, so there's going to be some intense torque between where he lifts the key and the much thinner part with all the delicate teeth for the tumbler. Then again this is a world where catching a falling plane actually stops it instead of punching a Superman-shaped hole through it. That being said, if it were a regular key, that means the lock would also have to be a normal lock, thus vulnerable to a modest lockpick... or if the person breaking in wants to overthink things, they could literally just take a photo of the key on the floor, send the image to someone with a CNC router, and mill out a duplicate key. The hyper-dense key's weight wouldn't be the only security feature, rather its density allows it to withstand the forces Superman would be applying to shove the key into the keyhole, to move the tumbler's super springs (which would otherwise flatten the teeth of a regular steel key), and the torque applied when twisting the key to turn the super lock.

[@dazdob]

@@blarghmcblarghson1903 If it were a regular steel key then wouldn't the sheer force being applied to it from the magnet be enough to basically disintegrate it as it's lying on the ground anyway? Since, as you said, the key doesn't have uniform mass across its entire body.

If I asked you how much my dog weighed and handed him to you (chihuahua), you'd be able to guess within a 100% margin of error, right? It'd make no sense to think that such a tiny dog would weigh more than 20 lbs, especially considering he's only 10. Superman being that far off would be like you picking up my dog and saying it weighed roughly 250 tons. If Superman can't know the difference between 10 lbs and 250 tons, do you want him knocking on your door? God forbid he touches Lois. He might rip her in half.

If we follow the logic of Superman, making the key and a lock for it in the first place is way to much effort. I think simple solutions are the best, just make a door of this stuff, he would be the only one who can move it anyway. It would have also much more volume, so the material does not need to be as dense. Tough i cannot imagine any kind of hinge that could hold it. I just imagine it as a kind of trap door on top of the entrance. Due to the bigger surface area of the door you might also avoid it sinking into the ground, depending on the exact size and density.

With the weirdness of how water works, it may be even be diminished because the molecules expand as they get colder, so they can handle more as it gets colder over a wider area? Also, since the mass wouldn't necessarily sink in the snow when its momentum downward due to gravity is reduced enough to render it "at rest".

Kyle (I love the show, btw), could the key be an alloy? So, for it to be made of neutron star matter, it would be a thousand times thinner than a regular key. Ten times thinner than plastic wrap (for salad and stuff). . What if Superman made an alloy of neutron star and some other material? Sure, it sounds like you would still have a lot of neutron star matter, but in steel, only 1 or 2% is carbon. So, if we used the same for this alloy, it would only need to be 0.1% neutron star matter. That way, it can weigh as much as he says, and still have the normal shape of a key. As for why he would call it star matter instead of star matter alloy, well, often alloys are called by the name of the material that attributes to it its main characteristics, such as steel is sometimes called iron, and titanium and tungsten alloys are often just called titanium and tungsten. I'm glad to see how much this show has grown and improved, and am looking firward to see where it goes in 2019.

[@jannegrey]

Alloy is rather specific term. I think you meant dispersing the "neutron star material" inside molten steel and you have an "alloy" of sorts. I'll cover that in a second. But first let's think you just put a thin strip of it inside - just for weight, the rest of the key is not going to withstand both in tensile strength, as well as in gravitational forces. You'd have to disperse material, over Very Large KEY - the one at least like in the comic (that very big KEY, that makes superman look like Scrooge McDuck). Or like 100 times Larger. And specifically built to withstand stupid amount of forces (it would be that big, that if superman held it perpendicular to the surface it would snap - from the weight of steel alone), because if you try to pick it up, you'll pick only very tiny bit of that HEAVY KEY, because the rest is so heavy it would snap, from the forces of Gravity vs. you trying to pick it up - try picking up 500.000.000 kg of steel. You'd need approx. 5 GN of force to do that, and IDK if ANY material could withstand it. I could go like that for hours. The simplest answer is of course the real answer - You cannot take anything from neutron star without it snapping back into explosion of matter. But other assumptions make hilarious scenarios, my favorite - Obviously if he could withstand the pressure of gravitational pull of neutron star, he could hold part of it in his hand and keep on pressing, so it would remain the neutron star material (it makes me wonder from what is Superman built from? Since it definitely is not Protons and Neutrons in any configuration - he couldn't withstand the neutron star if he was made of normal matter no matter how tough). But if he picked, let's say amount of equivalent to small stone - so he could keep on pressing the material, it would be about 20 cm3. So if he got distracted for a second, while still keeping his fist closed and "safe", the gravitational pull, would make him punch himself in a face, with something of a mass of big island (or small continent). Not to mention, bringing it to earth, where upon being couple hundred feet from the ground he would get smacked by planet earth, or at least anything, that is not sticking very hard to it, like planes, houses, oceans, people, whales, People of Wales, and Earth itself, although it would not survive it, since being millimeters from Earth, it would start to pull earth apart (now that I think of it, maybe not - the mass of such an object would be probably around that the asteroid that wiped out the dinosaurs), even if not if it fell (and somehow didn't explode) it would impact the earth with such a force, that from tossing that to Supergirl - if she didn't catch it, would probably make enough debris and dust to bock the sun allover the world for couple of months. Also things like tides, and tidal forces etc. Maybe it was a stretch (I was trying to compare it to objects in the solar system, and this "neutron rock" came to only about 1x10^14 kg, so that's about 5 km radius moon - still something to be afraid of if dropped), but it was fun. Sorry for a long post, but Man - you gave me some crazy ideas ;) Thanks, and have a lovely afternoon.

[@mikelenz4000]

Isn't the problem with it being an alloy that they require atomic bonds? In neutron star "material" there are no bonds, only gravity acting like a pressure-cooker. Additional sci-fi tech or explanations (such as the DC universe having 52 earths or additional fundamental forces) is the only way to make that specific key explicable.

[@jannegrey]

@@mikelenz4000 Yes, that's why I also wrote it as an "alloy" of sorts. Since you would be making a "neutron stardust", drop it into small amount of let's say molten steel, then put it into the shape, and quickly quench it. It is the closest thing to an actual alloy, that would be possible "IF" you could make "neutron stardust" somehow not to explode.

ripghotihook That key would mess up earths gravity quite bad

[@fighteer1]

@@jorgerincon6874 There's not enough mass in it to noticeably change Earth's gravitational field at a macroscopic level, although there would be measurable local distortion. But it would sink right through the planet like the Earth were made of air, carving out a little key-sized hole as it oscillated back and forth. This would become superheated due to compression, and so it would leave a glowing hot trail of liquefied rock in its wake. Of course, we're assuming it doesn't instantly explode due to the loss of gravitational pressure required to maintain the degenerate state of its matter.

Can't the core of the key be neutron star dense for the weight and then encased in other material to make it big enough to hold? No one said the key has to be only one type of material. Then use the science for creating artificial gravity around Thor's hammer to contain the material of the neutron start within the key.

[@davidmatthews2773]

Given the weight of the neutron star core key, there is no material that could house it that wouldn't be obliterated once the key was laid on the ground. Assuming, of course, we're using known materials. It's possible that a shell was crafted from some material from another planet Superman has encountered over the years.

[@penguinwarcry]

@@davidmatthews2773 I know this is layering silly on silly, but hey what else is this channel for? Get the star core, use the science of Asgard to keep the gravity around the key core stable so it doesn't explode outward, suspend the core magnetically (not sure if that would play well with the magnet warping gravity of the star's density but...) maby something like talked about in the light saber episodes, and then, once you have your core stable and not interacting with anything, put a handle on it. Probably bigger than a house key at this point but also not unwieldy.

[@jordanconoly8348]

I had a similar idea to this but instead it deals with plating a white dwarf key with neutron star material. Kinda like how pennies are mostly zinc but plated in copper. My comment goes into more detail, check it out.

[@davidmatthews2773]

Based on Kyle's video about Magneto pulling the iron from someone's blood, the intensity of the magnetic field needed to suspend the core would likely kill the person trying to pick it up. As far as covering the neutron star core in white dwarf material, wouldn't the weight of the core compress the shell into neutron star densities once it was set down given that white dwarfs compress down into neutron stars?

[@Mike504]

[@DecepticonLeader]

Yes

[@awg0681]

If we run some numbers we can see how much that really is. First, you've written out 5 trillion kg, which is 5 billion metric tons. Superman states the key is half a million tons so that's "just" 500 million kg (500,000,000). As a percentage of the Earth's mass that's way, way, way.... way, way less than 1%. It's around 8.372404554588077695914266577361e-18 % of the Earth's mass. Even if the key were 5 billion (5,000,000,000) tons the exponent only goes down to -14 instead of -18, still a very very very small percentage of the Earth's mass. A spec of dust (weighing roughly 0.00000000753 kg) landing on a person weighing 84 kg (185 lbs) would have more of an impact on the person's motion/movement than Superman moving the key around, or even dropping it, on the Earth.

Hey, Kyle. I really love your show and i really wanted to get to footnotes, sooo. I have seen that people, with just photos of keys can create amazing replicas of them, that are good enough to unlock the doors the keys are from. And the key in superman's hand seems pretty generic, so someone with ill intent could in theory create a key and either 3d print it or machine it from metal to get in the fortress without picking up the key. Of course. This disregards maybe the key having specific properties that let you unlock. Maybe the lock is made from the same material and has some sory of spring where you have to be super strong to turn the key even if it is in, thus making that key the only possible to be put in the keyhole, making every other material shatter before it managed to unlock the door.

[@aleech123]

that may not work looking at how "dense" the key material is, i would assume that the lock mechanism would be of similar strength and hardness else (due to the hardness) the key itself would crush the little knobs inside the lock as Superman turns the key like running a stone through jelly also (assuming the key fabricating method works) the key "fabricator" would also need a machine that could provide the torque high enough to turn the key to overcome the lock's mechanism inertia to successfully unlock the door. don't mean to troll but just my 2 cents.... cheers....

[@AspLode]

Really, it's just another example of pointless escalation in comic books. If it's that important to keep the fortress of solitude secure, then it shouldn't be able to be opened without Superman present - creating some key schtick only creates an attack surface for a villain to interact with the fortress, given enough motivation to do so. And really, a villain defeated by the key would just deflect efforts to attack the fortress some other way and create another confrontation altogether focused entirely on a measurement of abilities. There's no actual plot as we're distracted by the semantics, which makes a half-billion-ton key just an extension of the poor writing involved in the first place.

[@rmsgrey]

@@AspLode Giving an obvious (apparent) vulnerability for attackers to (try to) exploit can help bolster security - it means you can predict how people are likely to attempt to get in and prepare for that specifically rather than having to defend against all possible attacks equally, and it also buys you additional time to detect the incursion attempt before they move on to something with an actual chance of working...

[@AspLode]

@@rmsgrey But that doesn't address the fact that a story-interaction between villain and Superman is being offloaded to some proxy which doesn't achieve anything new, because it's Superman's fortress and it represents Superman's abilities, so a villain attacking the fortress tests himself against Superman's abilities. It's just another way for Superman's abilities to leverage itself as an obstacle for the villain. It doesn't enhance the plot, it merely expands Superman which is pointless because Superman already expands in his stories to overcome any and all obstacles. Superman essentially states that the very mechanism by which the fortress can be accessed is limited to those of Superman's abilities, at which point "500 million tons, made out of a dying star's matter" doesn't mean anything more than "Only I can pick up this key". It's the same narrative masturbation which distracts all bad aspects of superhero stories. Going back to what you're saying, a Super-key for a Super-door to a Super-fort made by Superman as a nucleation point for an approaching villain would simply be super-tactics and yet-another-demonstration-of-Superman's-abilities, in this case his ability to out-think his adversaries. It doesn't do anything that the Super-weight of the Super-key already achieves, that is provide a barrier against interaction that is directly connected to Superman's abilities. Now, if the fortress were made by someone else and Superman had no choice but to trust this person's abilities and motivations, and the fortress sheltered something like a humongous cache of kryptonite or some other Superman hamartia, then it would be something substantial. Then it would mean something that he shows Lois the key. As it stands, Lois can't do anything with the information, he could be showing literally anyone the key. Hell, most of the rebuttals offered in the comments to the tune of "it's exclusive Kryptonian technology" to answer both "how does it weigh exactly 500-million-tons" and "what happens if a villain simply copies the shape of the key" further entrenches the fact that it doesn't matter, the whole key scene doesn't matter from a narrative perspective. It's just "Hey guys in case you forgot, Superman is extremely strong."

[@rmsgrey]

@@AspLode I suspect part of the reason for the super-heavy house-key is to be a "correction" to the older version where the Fortress had a lock so large that people could walk through it (assuming they survived the various booby traps) and was unlocked by a key disguised as an aircraft marker intended for use as a navigation aid by airplanes in flight that was too big for anyone to lift without heavy equipment. I've not read All-Star Superman, so I've got no chance of commenting on the scene in context, but as a taking someone home to meet the parents and/or giving them a key to your place, showing the juxtaposition of the mundane - a regular (looking) door key under a regular door mat - with the Super - the key being too heavy for most people to lift - as a reflection of Kal El's dual character as Clark Kent and Superman could reflect Kal opening up to Lois and showing her his true identity beneath the masks. It making sense or not as a Super-home security system is secondary, in that reading, to what it says about the characters and their relationship in that moment.

Doesn't matter how heavy it is. Just take a pic of it and craft your own key or take it to a locksmith.

[@hobomike6935]

Superman after reading this: (ಠ_ಠ) "oh, not good.....didn't think about that" *Rapidly flying home to change his security measures*

[@roobtube6707]

What about just picking the lock? The key is heavy and dense but he does not say anything about the keyhole itself. Am I wrong?

[@pegdude6125]

If the key has half a million tons of mass, then logically the door and the tumblers in the lock would have to have the mass and strength to withstand both the weight of the key and the force required to turn the key. So no you would not be able to pick the lock.

[@Riwillion]

@@pegdude6125 That is surely a faulty application of logic and science, since the key is used by Superman who is, well, superhumanly abled, and definitely can just insert the key carefully enough and then turn it perfectly around its axis without applying any force on the lock other than just what the turning motion produces, which cannot break the lock unless super fast, because the lock is of course made to accommodate for such a motion.

[@pegdude6125]

@@Riwillion Yes but we are talking about if one is able to pick lock the door. Logically speaking he wouldnt have it able to be picklocked, and the way of doing that, plus the way of dealing with the issues I mentioned above would be to make the door as dence in mass as the key. That way there would be no need for superman to be so careful with the key, and would ensure that the only way of opening the door is with that key. My logic is not faulty thank you very much.

If you could pick it up...should you....

[@MrsNegative1]

Hi, Kyle. I'm Joel from Germany. I've got a question that would need knowledge about the new Aquaman movie. If you have seen it, can you explain how Black-Mantas eye-lasers work? Could you make a episode about this.

[@patnaikunidivijprithvime6982]

Alternatively you could just mold the same key out of some other material find a way to exert equivalent force on the pins and youre golden

[@NeumanProductions]

Considering he has crushed coal into diamonds, could he take the dwarf star material and forcibly compress into a key and use kryptonian tech to maintain that form.

[@Eric-gn6yk]

Correct me if I'm wrong but assuming that Superman somehow did manage to make a key using neutron star material if we use the formula for gravitational force the key would exert about 3 N of force on a person 1 meter away from it. Would someone be able to perceive this? And if so, what would that even feel like? Also, great video!

[@FluorescentGreen5]

wouldnt it sink through the earth

[@Mastermind8908]

That's right, Kyle didn't go into that. Ignoring the nuclear explosion concept, the object is still dense enough to have a rather noticeable gravitation pull. Even if Sups' did hide it under a welcome mat, people would feel the pull and know where it is.

[@dans4323]

Maybe the key just has a neutrino star core and the surrounding material is a less dense kryptonian mantle keeping it from expanding.

[@scotrateezx2480]

One punch man doesn’t need a key he just needs one punch.. and he’s in.

[@dan_loup]

Not entirely sure if saitama can calculate the punch to only open the door instead of destroying the whole thing.

[@scotrateezx2480]

Either way he’s in or the inside is now outside.. so easy pickings.

[@Mysterialic]

Saitama isn't supposed to be a benchmark figure. He's a satirical character.

[@scotrateezx2480]

I know, he was made to make fun of superhero’s and they’re crazy stupid over the top powers and by doing so he became a bench mark character by accident.

[@notbob555]

@@Mysterialic You think Saitama cares about your opinions? Because he secretly does.

[@patsutherland6853]

Did you consider that he could have alloyed the dwarf star metal with neutron star material?

[@randomguy4167]

Pat Sutherland What does that even mean,you can’t “alloy” neutron star material.The stuff neutron stars are made of can barely be considered normal matter in the first place.This isn’t some common element but neutrons that are on the verge of becoming a black hole.Also let’s assume for a moment that you could alloy these materials,so you are saying he might have alloyed neutrons and electron degenerate matter?It’s not that your question is stupid but more that the question doesn’t even make sense in the first place.

[@papa_sarge]

Kyle, I am curious about the substances listed in the spectrograph puzzles in Marvel’s Spider-Man on the PS4. What are they? What is their use in everyday life? And what scientific applications do they have in modern science? Also, if they can realistically be used to make Doc Ock’s mechanical arms (which I doubt 🤷🏽‍♂️)?

[@yazanalj1975]

Not to mention that the key would sink to the core of the earth if it was placed on the ground

[@Lokistar13]

[@NinjaBearFilms]

Thickness of Ice can support weight is shown by P = Ah^2 where P is the load, h is the thickness of Ice, and A is a constant for flexural strength, which for ice is about 1. So a half a million tons (1,000,000,000 = 1 h^2) So the ice would need to be 31,622 inches thick at the North Pole where his fortress of solitude rests so the key wouldn’t crack the ice and fall to the bottom of the ocean. Or about a half mile thick. But the Artic Ice is only 2-3 meters thick. So Superman setting that half a million ton key under his door mat would crack the ice and sink the fortress of solitude under the water.

[@NinjaBearFilms]

Note, half a million tons = 1 billion pounds I used in the formula.

[@NinjaBearFilms]

And there are more robust formulas for minimum safe ice thickness that factor in surface area the weight is distributed. But since the normal house key shown is around one square inch give or take, I figured the simple formula would be sufficient.

[@samgeurdi6351]

His fortress doesn’t rest on the ice it grew from the core of the earth and broke ground so the key is actually resting on his fortress outside the entrance but is surrounded by ice and earthly soil.

[@NinjaBearFilms]

Not all versions of the Fortress of Solitude were in the north Artic either. But the version depicted in the reference to the heavy key is. Which has several times in various media been shown to have the Artic Ocean running under it. That it has risen up and separated from the growth point to rest in/on the ice.

[@samgeurdi6351]

NinjaBearFilms No he has one in the amazon jungle as recently too and one on the moon since rebirth and on in the South Pole. Same methodology though. The version this video is taking notes from is Grant Morrison’s 12 issue All-Star Superman. It’s the architecture of the structure that is built from its core to support many of his inventions criminals and so forth and for that reason it wouldn’t lie on anything weaker. You wouldn’t build a skyscraper on New York City if it wasn’t for the huge amount of bedrock it has that’s why you see skyscrapers there it would cave in otherwise. So the fortress structure is built from the core. That’s how the fortress is always emerging both in movies and comics. You’re only seeing the tip of it. But its not some floating corkscrew. What ever structural changes is done after is something Superman has done himself. He has a lot of animals extraterrestrial for example so he creates habitats for them so stuff gets changed.
