What if lightsabers are actuality laser sword? As you pointed out, in one of previous because Scienze episodes, lasers usually follow a straight trajectory.I have read that some researchers have found a way to curve light beans. What if a lightsaber is actually made of many individual curved beans that comes back in to the sword or a single "tangled" one? Like a laser loop. www.photonics.com/Article.aspx?AID=44160
I know right. I got stuck learning physics from boring old Professor Dick Solomon at Rutherford College. He never did anything cool like this. Then I transferred to CalTech and studied under even more boring Professor Sheldon Cooper. Why are all the other physics professors so boring and normal?
1 Yottawatt = 10^24 Watts. That is to say 1 Yottawatt is equal to 1,000,000,000,000,000,000,000,000 Watts. Which is to say 1 Septillion Watts. Just in case you were curious :)
Some comic book nerdery: Flash could touch it according to his new power of momentum absorption. Anything with momentum he can bring to a complete stop. If heat is just kinetic energy of a collection of molecules, then theoretically he can prevent heat from hurting him. Even extinguish the whole saber possibly. He has to have some capability to deal with heat since he can run so fast that the atmosphere compresses around him would fuse.
@@froggy2247 considering his powers aren't like a physical enhancement ie: (Quicksilver, Dash, ect) but come from an imaginary fundamental force, I don't think they were trying to be to realistic.
So, he literally can run toward the Sun without danger (except from an oxygen perspective) ? From a realistic point of view, that's kind of weird, isn't ?
Canonically the lightsabre doesn’t transfer energy till contact is because it’s a closed loop of energy (not laser, shut up George) and it only transfer the energy to Matter in direct contact with the loop. The “light” is the interaction of the air with the energy loop and it’s supposedly not getting any hotter than a neon light. So while it’s putting out a ton of energy it’s not putting out a ton of heat until it interacts with the object. And most of the energy is reabsorbed into the handle/battery. Making it very energy efficient when it’s not cutting. And also why it only “cuts” on the flesh it passes through instead of exploding the entire human in a flash steam explosion of blood and gooey bits. Now is this magical non-heat loss energy loop actually possible? I don’t think so, but I’m not stuck in the Because Science void to think on it.
Magical Timey Whimey reasons. It’s been a while since I read the EU explanation. But it was something along the lines of the energy loop was very narrow and thinner than the visible “blade” and by the time the air molecules reach the edge of the blade and stop glowing they’ve lost the energy gained from passing through it.
But the short was that the air never got hotter than a neon light bulb and the denser the matter the more/faster energy is transferred into it. Because Magic!
Sure......except that you were asked to touch the "saber"......as the "hilt" could be defined for a large selection of different weapons. The hilt is not what makes makes the weapon what it is, otherwise there would be a weapon known only as a hilt.
@@minimags6720 Yes. If you did that and the lightsaber was turned off, it's literally a lightsaber with a metal blade stuck on it. If you turned it on, depending on where it was, the lightsaber's beam would probably just vaporize the blade. That's because a lightsaber is literally just a hilt that, when activated, produces an energy beam. When it's turned off, it's literally just Oops, All Hilt!
I have a topic literal nobody talked about (thumb up so he may see it) In the recent animes episode of One Piece, a certain minor villan, Oven, who has the power to heat up his body to ridiculous temperatures, showed himself able to BOIL A SECTION OF THE OCEAN by just dipping his hands up to his elbows. What it would be great to know is how hot must his arms be, and if it's even possible to boil a small part of the sea.
You would need to know the volume of the water being boiled. At sea level water boils at 212 F. So the furthest edge of the boiling area would need to at least reach and maintain that temp. The thing is, water is very resistant to temp changes (that's why berry farmers spray the berries before a freeze, because it insulates the fruit). You could in theory use his equation, p= l/ 4π^2 backwards plugging in the energy required to heat the water from it's initial temp to 212 for P, but there's also the fact that energy is being leeched to the surrounding water as well. I'm just a physicist for fun though, I'm not near the level of discount internet Thor here
@@mmcmullen8543 I took chemist and physics as part of my first mayor (before realizing that was not the career I wanted to follow) so I'm aware of how the surrounding water leeches, that's exactly why I was wondering if that feat is even possible. According to what you're telling me, it is, as long as the heat produced by Oven overpowers the heat leeched by the surrounding section of the sea.
It would certainly be possible to boil a certain volume of water around a super-heated pipe (or arm) - even in the ocean. You see this kind of activity around ocean thermal vents all the time. How LARGE a volume you could realistically boil from a small starting point is hard to say. I don't think there's any particular limit, except that at some point you're going to reach a temperature at your arm (or pipe/vent/whatever), that is so crazy hot that instead of simply 'boiling' the water, you end up with more of a massive steam explosion and then the physics starts to get wonky as you have to deal with a rapidly expanding sphere of super-heated gas contesting with the surrounding weight of the ocean and so on and so forth, featuring rebounding shock waves and all kinds of craziness. The physics at that point probably require a super-computer to keep track of, not a whiteboard. This kind of thing happens when you set off a nuclear bomb underwater.
Well there's a certain threshold you get where his arms will be so hot that he instantly vaporizes water, creating a steam barrier that prevents efficient transfer of heat from his arms to the ocean, also known as the Ledenfrost Effect. The main problem is that the surface area of his arms is too small to heat more than just what is immediately around his arms. One possibility to remedy that is maybe his arms start to give off significant radiated heat and glow, which is normally not that efficient at heating transparent water but perhaps it's got significant impurities which would help increase the effective surface by which that energy is transferred to the water to heat it. Another factor working against arm-to-ocean heat transfer is that at the ocean's surface you have the least amount of pressure, reducing the force by which the water pushes toward his arms and reducing the threshold for aforementioned Ledenfrost Effect. As his arms get hotter, all that happens is that the temperature of the steam barrier becomes greater but the mechanical force that prevents more efficient contact heating doesn't go away, and instead you just get hotter steam jetting out from that thin vapor "sleeve" that would envelop his pseudo-submerged arms. Of course you could just keep cranking that temperature dial and start plugging in bigger numbers. So... ocean water isn't just H2O, you're producing steam but also vaporizing the impurities which depend on the body of water but typically include some kind of chloride like MgCl, which is reactive and when superheated as a product of high-temperature saltwater vaporization (such as what happens where lava meets water) can produce Hydrochloric acid... so... Oven would be bathing himself in superheated acid vapor. Keep cranking the temps up and things just get worse, like supercritical water vapor will undergo hydrolysis or decompose into Hydrogen and Oxygen, or just a bevy of weird interactions involving superheated plasma. Anyway yeah the math gets straight-up hostile with this one.
I love this kind of episodes. If the Flash moved fast enough towards a lightsaber, the light emitted by the saber would be blueshifted into the x-ray or gamma spectrum. And a 35 MW x-ray/gamma ray source...is deadly. Assuming he starts from save distance 50 m and moves to 1 m distance (roughly an arms length), to touch it and his body blocks roughly 1 m², how much radiation from the lightsaber does he absorb at a various speeds? Also considerng radiation with a wavelength of less than 250 nm is ionizing radiation, and a dosis in such radiation is measured in Sievert (Sv). 5 Sv is a deadly radiation dosis for 50% of people after 30 days. Further assuming the Flash weighs about 70 kg, he should absorb less than 350 J (=5 Sv) in his whole body to have a 50% chance of living after 30 days (radiation sickness will still be horrible though). So..I did some excel-ing. (this all assumes he is running toward a 35 MW ionizing radiation source) At 1 m/s (slow walking) he would absorb 4.5 MJ. Toast. At 10 m/s (Usain Bolt) he would absorb 450 kJ. Instant Death. At 343 m/s (speed of sound) he would absorb 13 kJ. Almost instant Death. At 1000 m/s (fast bullets) he would absorb 4.5 kJ. Still Dead. only at 13000 m/s he would absorb less than 350 J. Maybe Dead. However, 13 km/s is not nearly enough to blueshift the radiation of the lightsaber into ionizing radiation (for that he would need to move ~90000 km/s) or 1/3 lightspeed. So... no danger for the Flash to die of radiation sickness. However, If he approached with 90000 km/s to the lightsaber he would receive (700 µSv). Thats what a normal person receives from natural radiation in a year. So..probably increased risk of cancer for the Flash.
I see your well thought-out and expertly written scientific examination of an unexplored risk of running towards a Lightsaber and I raise you one Speed Force. There, problem solved, lol.
Brother absolutely loved your work on this just one quick addition did you take in to the equation the inverse square law? That would greatly change the rate of LET
@@JustMakeItNazi I did. For each full meter of distance I calculated the size of the surrounding sphere of radiation and how much 1 m² of that would absorb per second. Then traversing the full 49 m can be approximated by adding all of that together (only approximation though, for more accurancy a integration would need to happen, but I didnt wanted to go THAT deep) and dividing the result by the speed the Flash actually runs through.
3:06 You seem to be implying that 70°C is double 35°C when in actuality, we can only talk about doubling temperature with Kelvin. 35°C is about 308K, so doubling this would be 616K, or about 343°C. :3 I mean, it is technically "not even doubling."
@@Monstermoerder1 It depends on the thermal transfer capacity of a medium. Air is a poor thermal conductor. Consider that you can put your hand in an oven (not touching any surface or object) that is basically 350˚F or 177˚C and remove it without any damage. Doing the same in deep fryer oil of the same temperature is a trip to the ER. A dry sauna (no steam) would be more tolerable as evaporation of sweat still occurs (evaporation of water requires a lot of energy). A steamy sauna would cause you to overheat faster as humid air is both a better conductor of heat but it would also inhibit evaporation of sweat. Also, consider that you can walk out side on a below freezing day for short periods without gloves but immerse your hand in water with ice and it gets uncomfortable in seconds.
@@Monstermoerder1 You aren't directly touching the temperature in the sauna for one, two it's spread out over a great distance meaning that the whole temperature change isn't happening that rapidly. In the math Kyle is showing he is meaning that the flesh of your finger actually gets to 70°C, where in a sauna your actual skin never should reach the temperature of the sauna.
@@tiacho2893 Apparently humans can stand upwards of 400F of completely dry air for minutes on end (assuming the have access to reasonably cool water as you'd sweat enough to dehydrate very quickly).
Personally, I always figured that the type of energy produced by a lightsaber is a sort of plasma that primarily effects more rigid molecular structures of solid matter and has less effect on liquids and even less on gases. Of course, that could be the influence of similar sheilds to those that we see in docking bays that stop air from passing through, but don't stop solid matter.
What about heat transfer rate? If Flash wanted to touch a still igniting lightsaber vs the one that has been on for a minute, the time would be drastically different, right?
I suppose Kyle here made the assumption the ionized plasma inside the respective region of space has already reached thermal equilibrium with the implied heating device.But you are absolutely right,because science...
That's what the timing is all about. Clearly the energy is enough to burn the flash, but it wouldn't have time to transfer enough of it to do damage before the Flash could remove his finger. Kyle just didn't show the math for that here.
Honestly though, the lightsaber has a magnetic field to keep the plasma in place, but wouldn’t the magnetic field also keep the warmth in place so you don’t burn your hand? We are talking about a Sience Fiction lasersword after all.
Of course it would, to conserve energy and protect the wielder. The force field recycles 99.99% of that heat energy back into the power required to sustain the light beam. Otherwise you'd run out of battery in like (math math math...) 13.6 seconds. Same concept as the stillsuit in Dune. Basic conservation.
Yes we can. The same technology is currently being used inside fusion reactors to stop the plasma melting the reaction chamber walls. We've been using magnetic fields to manipulate heat energy for decades now... 🍄
No because heat radiation is literally light photons that have no mass or charge. We can control the ionized plasma in fusion reactors with magnetism to keep it away from the walls enough that it won't melt them but you can't directly control the light emitted as radiation. Also in fusion reactors it's a very tiny amount of ionized gas being fused at once in a tiny flash, then cooling time is allowed.
Clearly The Flash has always been impervious, or at least highly resistant to heat. At even his "low" speeds he can compress the air in front of him like a space craft entering the atmosphere. At his high relativistic speeds he is going so fast he would be blue shifting the light in front of him into higher energies like x-rays and gamma rays. I'm not even going to go into the details of the friction generated by his thighs and other parts rubbing together while he's running. My point is that the flash could definitely touch a lightsaber no math required, but where's the fun in that?
Yeah but if the flash took a lightsaber by the handle and ran as fast as he could, couldn't he outrun the heat radiating from the realistic lightsaber so he could run with it and touch the blade at the same time? Although, that would be pretty horrible for whatever was in the flash's path.
Normally yes, but once you add "speed force" to the equation somehow it'll just end up in his personal aura and would just be relative to him and no outside force/law (I'm guessing)
My friend and I think we've figured out the superheated lightsaber problem. We think that the beam is contained within a "ray shield," which is to say the same technology that necessitated using torpedoes instead of lasers when attacking the first Death Star. This would then account for the shape of the blade and why you can't cross saber beams, and also why normal matter like blast doors and arms can be burned through by touching the blade, since normal matter can go through a ray shield. Fixes all the problems.
With same thing I mean that the lightsaber is not an actual blade so he doesn't even have to phase through it- the heat is the dangerous part and since the heat is not harming you when you're fast enough, he just doesn't care
The phasing part of the Flash's power would require matching quantum frequencies, which is something we actually don't know much about, so it is hard to evaluate it with actual science. Now the comics have said that he is just matching the resonant vibrations of molecules, but that doesn't make sense since they don't stop existing at those frequencies, they actually just absorb more energy. So he can't move through them or anything, they are still there. Most of the comic writers haven't done much real reading about this to even try to explain it in a semi- realistic way. It's just magic essentially.
The speed force could also function like a warp drive (which go above light speed) and contract space in front of him and expand behind meaning mass is irrelevant
Warp drive doesn't go faster than light. It just moves you from one location in space to another quicker than it would take light to travel. "Going faster than light" implies a speed, and a speed implies travel. But you don't travel with a warp drive. Technically speaking, a warp drive is the slowest method of travel. You get to your destination the quickest, but you don't actually travel anywhere.
@@R3_dacted0 velocity (aka how fast) is calculated using the distance between two points divided by the amount of time it takes to get from one point to the other. As such warping is faster than the speed of light. And warping is still traveling, you're still going from one place to another.
The way I understand it, warp drive isn't moving in the same way. If light could go through warp space it would be going faster than any vessel in it. It is best to think of a warp drive as a shortcut rather than a normal path.
Flash can break the sound barrier, light barrier, time barrier, and speed force barrier. Therefore he can violate causality and accomplish just about anything. Also from a comic scene in which Flash outruns a nuke, Flash runs almost 13 trillion c (13 trillion times the speed of light). Rescuing half a million people.
Hey Kyle. Through the video you seem to imply that the lightsaber is running at full power all of the time. I would imagine that in actual fact the light saber would act in a way to keep the "blade" at it's operating temperature. i.e when it is just idling it would output just enough energy to contract the energy lost to the surroundings, however when it was in contact with the door in the Phantom Menace it would have been losing a large amount of energy to the door (35MW) and therefore would have been operating at max capacity(maybe). This would explain how the Jedi aren't burnt due to the power output of there own lightsabers.
Why has never mentioned the fact, lightsaber not withstanding, that Qui Gon's hand is less than an inch a way from molten metal as he burns through the door. His hands should have been severely burned.
At around 2:15, you said that you "refused to put the Flash's top speed beyond the speed of light because physics." I agree, but I'm not sure if you should have. In one of your videos (I forget which one), I think that you said that the flash had to run "...faster than instantaneous-ness itself..." Also, according towww.dailydot.com/parsec/how-fast-is-the-flash/, "In issue #138, Wally gets recruited for a competition of speedsters from infinite dimensions held by some ultra-dimensional beings with some major gambling problems. The losers’ home worlds would be destroyed if they lost. Seeing this entire game as an unnecessary loss of life, the Flash upped the ante. He bets the alien gamblers that he can beat them in a race back to Earth. Given that they can teleport, it looks like a guaranteed loss because, conceivably, nothing is faster than instant transmission. However, the Flash gets all 5 billion people on the planet to agree to run so that he can borrow their kinetic energy and beats the space overlords in record time." Love your videos, keep up the good work. You are the best.
Silly science like that is part of why I'm not a fan of DC. It's just not as believable to me as Marvel tends to be. Marvel has some problems too (obviously) but I feel the explanations behind them are far less ridiculous. That said, refusal to calculate the Flash's speed at greater than C is due to a couple reasons. One of which is many calculations approach infinite answers. Also, C is the speed of *causality* since the "speed of light" per-se isn't the absolute speed limit (it can be slower in different mediums for example. We can create "photonic booms", where the speed of light through said medium is actually exceeded and you get a flash of light). Causality, on the other hand, is what C stands for in calculations. Which makes it a bit easier to understand the next bit: the nuclear forces that bind our bodies together on the atomic level begin to break down and fail at C. In other words, the atoms can no longer "communicate" with each other, atomic bonds break, whole atoms get ripped apart to elementary particles. In other words, if you were able to achieve the speed of causality, you would basically vanish into a cloud of... you.
@@calvindibartolo2686 The C in E=MCsquared. (sorry, I don't know how to do a superscript for the 2). The C is for Celeritus, which is the greek word for speed. Since light (in a vacuum) has the highest speed possible it best suits the concept of speed. Causality is an inference to this maximum speed, and I don't know if it has been mathematicly proven. If it has then good on you for knowing that. However, as written the C was for Celeritus. A small correction to be sure. But an important distinction
Hey Kyle, at the end of season 2 of the Walking Dead they say that the zombies would level the house, but I think that the zombies would just squish themselves on it. Would be a neat idea for an episode. Keep in mind that the house was raised off the ground so it looks like the floor is roughly chest hight. Keep up the great work.
Would the Flash first be electrocuted before burned? After all, his finger would have to pass through an important magnetic field surrounded by an important electric current ? Considering that you've assumed (some episodes ago) that lightsabers are 'plasma saber', with a huge magnetic field encapsulating some air, then an electric current is running out the magnetic field causing an electron avalanche (remember this episode ?) , so what are you considering as touching a lightsaber? The plasmasaber explanation allows us to neglect the approach problem (radiated heat from 50 m of a lightsaber), but again, what the Flash would be touching. And then, because electron (from current) would be accelerated by the magnetic field, is this possible that those electrons are relativistic (moving to a speed near lightspeed), and so, could interact with the Flash, electrocuting him before he can touch the plasma region?
Well it's not an assumption on how lightsabers work..reguardless of how much Lucas calls them "laser swords" they are canonically plasma blades contained within a magnetic field that somehow contains the heat of the plasma as well. The flash can go fast enough to break the time barrier so I think he pretty much can touch the Lightsaber all he wants with no problems at all even with the magnetic field in the way..he's also able to vibrate his body fast enough that he can phase through objects on a molecular level..he's been able to do that for ages so that'll probably be a factor too.
I understand what you mean, but just to be sure, how the Flash can break the time barrier? If you want to break the sound barrier, you've got to go faster than the speed of sound, so if you want to break the time barrier, you've got to go faster than light speed? That's exactly where I stop considering the Flash superpower.... Because Physics !
@@marcelsevigny4957 Given Einstein's theory of relativity I suppose that's what has to happen since it has been shown that time slows down the closer to light speed you get...so it leads one to assume that if the Flash runs or spins faster than light speed by x amount then he can time travel or completely break the time barrier..that was the whole point behind the Flashpoint movie after all ..All I know is that it's the Flash running fast enough that he broke the time barrier that usually is behind DC rebooting it's whole universe or retconning something about half the time...there was a time when I was watching an old Superboy cartoon rerun (waaay back in the day) and he (Superboy) spun in place fast enough counterclockwise he went back to the medieval period..then when he was done with his time trip he spun clockwise fast enough to go back to the present...Time really is DC's plaything when they wanna show just how broken you can make a power or character...like that time Superman couldn't save Lois in time so he reversed the spin of the entire planet Earth by shear gravitational speed of his own flight around it and that SOMEHOW wound time back so he could save her..
Honestly I always assumed most of the energy generated was used to contain the plasma into it's shape. Like 80% is used to contain and shape the blade, and the rest is the actual cutting blade. That's how it can be used to block projectiles and lasers, as there's a pretty strong forcefield in place already.
Hey kyle, if ant man goes sub atomic, can he still hear sound ? Since sound is considered as vibration of air molecules, now if he is less than size of air molecule then it'll be like he is literally in between molecules ( in a compression part of wave or rarefaction part of wave) ?
It doesn't have to be air molecules though, any kind of medium is fine including our own body. So at least anything antman touches or his own bodily functions that have enough energy to vibrate his body will be registered as a sound of somekind.
@LauriNiilo Practically speaking, I think in the human body apart from cranial & ear bones, rest of them are not perfect sound information conductors. ( google glasses ), otherwise we can simply attach ear phones to the arms or elsewhere, can't we !
But what if we assumed that the lightsaber crystals can control the force and that they could create some sort of force field that prevented the heat from escaping the saber?
Then how would it burn something if there's a force field around it? And if you say it releases the force field when being swung then you have the same problem presented in the video
or, kyle is wrong, plasma cutters reach 25k celsius, the surface of the sun - 5600 celsius, no ones getting sunburn from the heat of plasma cutters. Lightsabers are ionized plasma contained in a magnetic field
My biggest question is: could The Flash grab onto the (non-realistic) lightsaber long enough to wrench it out of someone's grasp? (He would get to use his super speed to overpower the opponent's grip, since he can apply more force in the same amount of time.) It would be very useful to run around disarming Jedi with your bare (or suited) hands. Also, just want to point out that according to the TV show, The Flash's suit is specifically designed to be heat-resistant in order to counteract the heat produced by friction with the air at high speeds.
I know this is kinda missing the point of your question, but if the Flash is fast enough to touch lightsabers without damage, he's fast enough to just grab the hilt of the lightsabers without having to worry about the blade. Or, just grab them off the Jedi's belts before they even reach for them. Grabbing by the blade would be about the friction between his hands and the plasma. It would probably be like grasping at smoke.
Hey Kyle please do a video on all of Gundam's beam weapons( excluding Beamsabers as they are giant lightsabers) as a live action Gundam movie was announced.
...first we'd have to figure out just how the hell Minovsky particles work in the various Gundam universes...at their base though all the beam guns are pretty much charged particle canons...so..the closest thing we have to how that would work is a lightning bolt so we could work from there...Beam Sabers/Daggers/Javelins on the other hand require some way to contain and shape the energy so that's a very different kettle of fish.
Howdy Kyle! I have a question and a possible idea for another video. In the movie "John Hancock" there is a scene in which John stops a trail in it's tracks to save the guy stuck on the tracks. If we accept super strength scientifically, what would be the actual outcome? If he becomes dense enough to stop several tons if freight, wouldn't he just sink into the ground? And if he was flying and using speed to counter the speed of the train with density, would the steel of the train withstand his cutting force, or would his body slice the train in two like how the mythbusters did with a car. As always love your show, make sure you are getting plenty of rest!
Woudn't the Flash hit more photons/second (but less in total as the lightsaber would have less time to radiate heat) while going towards the lightsaber at near C speeds? On top of that woudn't he be hit by far less photons as he's running away as fewer would catch up to him at his top relativistically allowed speed? As a result the flash would feel the heat as he runs towards the lightsaber but running away from it would feel relatively room temperature? If anything this should get a snarky remark out of the flash. (all this assumnes that the air friction would not have reduced him into a puff of gasses, etc.) P.S. LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD.
30 km/s isn't a relativistic velocity. But the constance of light speed is the reason for relativistic effects. The light coming at you and the light going away are moving at the same velocity, even when you are moving at a significant velocity. You wouldn't get hit with more photons running toward the light than away from it. It would be the same. Time distorts to keep the relative velocity constant.
So I know this is an older video...but please tell me someone has pointed out at some point that flash has outrun light before...so he can most definitely run faster than lightspeed, due to the speed force making physics its beeotch
Great episode Kyle, i just want to say that the fact that you think a "laser sword" would have to irradiate heat all around it to be realistic it's not a given, some pepole in the past thought that making something like a nuclear bomb would be impossible, but as you know with time and devolpment we achived great and terrible things, maybe in the future we are gonna be able to contain heat and light in such a way that making a "laser sword" would be possible.
unless you could encapsulate the "laser sword" in a vacuum, thereby making heat transmission only possible through passive radiation, then I think it might be doable. Otherwise the saber heats the air around it through conduction (physical contact) which then spreads as more and more thermal energy is dumped into the air molecules surrounding it.
Well, it gives off light, so it's already putting out at least one wavelength of radiation that isn't blocked. It would need to have some kind of (completely unknown) field around it to prevent any other spectra of radiation from escaping. If you can do that you might as well make the light-saber invisible while you are at it - by blocking off the visible light as well - in order to make it that much harder to defend against. However, the imaginary field that's somehow stopping all this radiation from escaping has to at the same time be permeable to matter, otherwise the blade of the light saber would simply hit things and bounce off them without heating them up at all. Suffice to say that we don't have any force in physics that's even remotely capable of doing all these things at once, and Kyle's show tries to stick with 'known physics' as much as is possible.
@@Vastin - Making the beam invisible might not be the best idea from a safety perspective, considering how devastating of a weapon it is with simple contact.
You are right to a point brother the only thing is that if you do this with say some kind of force shield all you have is a fancy nuclear powdered light bulb. It would be no different than the shell of an incandescent light.
The lightsaber actually has a plasma shield which stops the heat from coming out and killing the Jedi or sith and helps it keep its shape…although the force is involved in it there is an explanation at least.
A light saber's target would also have to be thought of in means of density, material, reflectivity, as well as speed. This is because while intensely hot, the photons that make up the blade are traveling at the SOL.
Back in the 70s it was established that a lightsaber was a form of stellarater. A conical magnetic jar containing high energy hydrogen plasma. That seemed an elegant solution which tied up every aspect of the depictions of lightsabers with a nice bow. I'm not sure why the fandom had moved away from that idea, but it does seem to have done so. Indulging that idea for a moment it would eliminate the heat radiation problem since it is the interaction with solid matter that causes the heat transfer in plasma. If the magnetic field prevents the plasma from interacting directly wirh the medium, then there would be no heat transfer.
wow fr thankyou for this ancient fun fact, I've never considered thought of there being a magnetic field🤔..a type of magnetic field containing high energy plasma makes so much sense too💡
My co-worker fell from a roof of an industrial building 22.8m hitting asphalt. He survived ang aquired life changing injuries, but he can still walk and talk. He was kinda short, a bit chubby and a little slow when it happened. He isn't working anymore cause early / health insurance ritirement. Therefore I'm unaware of his current status or if he is still chubby.
have you guys done "could the flash escape force push/pull/hold" because Im curious to know if he could dodge such an attack, assuming this wasnt already done in a comic in some form.
In a comic named "The Human Race", Flash once traveled a very far distance and beat an instant teleported in a race, please consider doing an episode on this since I am pretty sure that he is moving faster than light (according to another TH-cam channel called The Imaginary Axis.)
Ok, I have mentioned this before, but your Science fu is week here. Every time you tell us that a Lightsaber must be a Plaza based weapon, you are not using Science. A scientific theory must give way once it’s observed to not fit the situations. You can’t take only one aspect of an observation, in this case, the cutting power of a lightsaber in one scene, and ignore the other aspects of the observation. If the theory does not account for all the observed aspects, it is disproved. In this case, your theory states that a lightsaber is a plasma blade. This theory is proved by you by the heat necessary to cut through the metal door in the Phantom Menace. However, this theory also assumes that the Jedi holding it would burst into flame when igniting the weapon... and the Jedi and those nearby them remain in charbroiled. So the theory is automatically bad, and should be discarded. How about you use Science. And try to create a theory that agrees with all the observed effects of a lightsaber? I suggest, again, that Forcefields are a Star Wars technology that is used over and over again. A super sharp, quickly vibrating field of force would cut through a steel door... and create heat as a side effect, by it’s friction. Yes. I know we have no good physics describing how such a field of force could exist... but it is a theory that allows for all observed effects of a lightsaber. Science that! Please. Love the show.
Kinda fits the evolution of the weapon. I had the technical manuals as a kid. The lightsaber was originally way back a vibroblade. Logical evolution to go from vibrating a solid piece of metal to some kind of energy field.
Yeah, it always bugs me when he makes that assumption. Whatever the mechanism at work, it's clearly contained. I would just work with the temperature calculation for the cylinder and assume it doesn't radiate any more energy than a high intensity fluorescent tube of the same size. If it was going to burn everyone within 30 m it would blind everyone within an even greater distance. Even if it was that hot and only conducted heat by direct contact, the air draft would be a problem every time it was turned on. Clearly, none of those things happen in the movies.
I'm just watching these videos. He said the energy output from the lightsaber is about 4mw. Enough to power 1000 homes. Makes a difference. He based the rest of his equations off of that.
The flash has been known to run much much faster than light, its something about the "speedforce" (the thing that gives him his powers) allowing him to defy time and space
Probably. The amount of thermal power transferred to his hand/body as he passed through the lightsaber would be on the same order of magnitude (or maybe a bit more, but whatever) as what's being discussed here, and since the flash can go lightspeed... you get the point. He would have zero problem doing that.
@@thelegendarysupersaiyanbro6535 he would have to move faster 10billion light years per second he would hit something on the way and he has norhing to run on so no
Nice idea. (Though you didn't mention the Flash canon idea of a "force field" surrounding him & protecting him from things like air friction.) Suggested ideas: • The Flash often pulls a trick where he appears to be in multiple places simultaneously. This is explained by him moving continuously from point to point & back again extremely quickly, while also remaining at each location just long enough for a significant enough amount of light to reflect off off him & through to the eyes/retina/ brain of the viewer. *What the top number of light illusion duplicates that can be produced by The Flash at any given time?* (Spacing them spread out as much as possible, but keeping them close enough so that they can still appear to be a threat. Also considering how fast our eyes/brain system works.) • Lightsabers - *How could you produce a way of protecting the user from the energy that is being emmitted?* (Note that it wouldn't be all just light or heat either.) • *Is the Goblin Glider from Spiderman possible with current computer controlled fan blade/jet propulsion systems?* • *What known Nootropics approach the capabilities of the drugs from the movies Limitless & Lucy?* • *Which has more acoustic energy, a lightning strike or a Hulk clap?* [B|S])
You should consider that in the movies where a light saber is used, they don't need to protect themself from simply holding it. There for the handle should offer some protection, regardless of if we understand how.
It certainly would when you stick it in a big metal door. At that point the door itself is forced to absorb most of that radiation - which it would then quickly re-radiate out into its surroundings, posing almost as much of a hazard as the un-shielded blade itself would.
@@Vastin That awkward moment when you're trying to hold your light saber in, and the black body radiation just gets too hot. At some point it's going to force you to pull out.
Hey, Kyle. Love the show (and this video), but... Hang on, what about that giant thing that produces plasma but it doesn't destroy anything because it is restrained by a giant magnetic field, that thing you've talked about in other episodes of Because Science? Wouldn't that be applied so that the lightsaber (if it were plasma that "cuts" instead of plasma being just a bi-product) only destroyed what it comes into contact with? After all, we have created many things several times hotter than the surface of the sun.
@@ninjahombrepalito1721 You can in fact propel yourself fast enough horizontally tangent to the earth and still end up in space with enough speed. Also the tokamak or the device you refer to still get's extremely hot. They just use principles of thermodynamics to make sure the heat doesn't get out of the controlled environment they house them in. He talks about this is previous episodes, where he talks about the world's largest temperature gradient by distance. One main reason they don't melt everything is they create a vacuum or "void" around the system so that heat has no medium to flow through.
But you are right it would take more energy or a faster velocity or speed to escape the earth if traveling horizontally rather than if vertically. That being said if Kyle's number of 30 Km/s is held true, and the escape velocity of earth is around 11.186 km/s. It can be easily stated with high confidence that even this would still be sufficient. Mainly as going vertically versus horizontally isn't that large of a change. All it does is change the distance or r in which you are affected by earth's gravity well since earth is a sphere how much it would change would depend largely on the point you are leaving from.
The tokamak does take damage btw. If you look up videos of it when the mag fields collapse the plasma in it is sort of decompressed all at once and leaves burns on the walls of the machine
It’d be neat if Disney commented (or made cannon) that Jedi constantly use the force to suppress the radiation/thermal energy for the blade, keeping it confined within like an arms reach.
Flash can move infinitely fast, light and everything else, except for other speedsters, are completely still to him. He can perceive and react to events in under an attosecond. Light would travel 0.3 nanometers in an attosecond. A nanometer is just 1 billionth of a meter. A hydrogen atom is 0.1 nanometers in length. So yeah, the flash is ridiculously fast, so much faster than pretty much anything else that it isn't even funny.

Some comic book nerdery: Flash could touch it according to his new power of momentum absorption. Anything with momentum he can bring to a complete stop. If heat is just kinetic energy of a collection of molecules, then theoretically he can prevent heat from hurting him. Even extinguish the whole saber possibly. He has to have some capability to deal with heat since he can run so fast that the atmosphere compresses around him would fuse.

@@marcelsevigny4957 Comic books... You don't expect that?
Canonically the lightsabre doesn’t transfer energy till contact is because it’s a closed loop of energy (not laser, shut up George) and it only transfer the energy to Matter in direct contact with the loop.
The “light” is the interaction of the air with the energy loop and it’s supposedly not getting any hotter than a neon light.
So while it’s putting out a ton of energy it’s not putting out a ton of heat until it interacts with the object. And most of the energy is reabsorbed into the handle/battery. Making it very energy efficient when it’s not cutting.
And also why it only “cuts” on the flesh it passes through instead of exploding the entire human in a flash steam explosion of blood and gooey bits.
Now is this magical non-heat loss energy loop actually possible?
I don’t think so, but I’m not stuck in the Because Science void to think on it.
Air IS matter, though, so you'd be heating the air to unbearable temperatures relatively quickly...
Magical Timey Whimey reasons.
It’s been a while since I read the EU explanation. But it was something along the lines of the energy loop was very narrow and thinner than the visible “blade” and by the time the air molecules reach the edge of the blade and stop glowing they’ve lost the energy gained from passing through it.
@@NinjaBearFilms I swear, I read your comment and was wondering when the hell the EU made regulations on Star Wars for a couple seconds...!😂😂😂
But the short was that the air never got hotter than a neon light bulb and the denser the matter the more/faster energy is transferred into it.

I have a topic literal nobody talked about (thumb up so he may see it)
In the recent animes episode of One Piece, a certain minor villan, Oven, who has the power to heat up his body to ridiculous temperatures, showed himself able to BOIL A SECTION OF THE OCEAN by just dipping his hands up to his elbows.
What it would be great to know is how hot must his arms be, and if it's even possible to boil a small part of the sea.
You would need to know the volume of the water being boiled. At sea level water boils at 212 F. So the furthest edge of the boiling area would need to at least reach and maintain that temp. The thing is, water is very resistant to temp changes (that's why berry farmers spray the berries before a freeze, because it insulates the fruit). You could in theory use his equation, p= l/ 4π^2 backwards plugging in the energy required to heat the water from it's initial temp to 212 for P, but there's also the fact that energy is being leeched to the surrounding water as well. I'm just a physicist for fun though, I'm not near the level of discount internet Thor here
@@mmcmullen8543
I took chemist and physics as part of my first mayor (before realizing that was not the career I wanted to follow) so I'm aware of how the surrounding water leeches, that's exactly why I was wondering if that feat is even possible. According to what you're telling me, it is, as long as the heat produced by Oven overpowers the heat leeched by the surrounding section of the sea.
It would certainly be possible to boil a certain volume of water around a super-heated pipe (or arm) - even in the ocean. You see this kind of activity around ocean thermal vents all the time. How LARGE a volume you could realistically boil from a small starting point is hard to say. I don't think there's any particular limit, except that at some point you're going to reach a temperature at your arm (or pipe/vent/whatever), that is so crazy hot that instead of simply 'boiling' the water, you end up with more of a massive steam explosion and then the physics starts to get wonky as you have to deal with a rapidly expanding sphere of super-heated gas contesting with the surrounding weight of the ocean and so on and so forth, featuring rebounding shock waves and all kinds of craziness. The physics at that point probably require a super-computer to keep track of, not a whiteboard.
This kind of thing happens when you set off a nuclear bomb underwater.
Well there's a certain threshold you get where his arms will be so hot that he instantly vaporizes water, creating a steam barrier that prevents efficient transfer of heat from his arms to the ocean, also known as the Ledenfrost Effect. The main problem is that the surface area of his arms is too small to heat more than just what is immediately around his arms. One possibility to remedy that is maybe his arms start to give off significant radiated heat and glow, which is normally not that efficient at heating transparent water but perhaps it's got significant impurities which would help increase the effective surface by which that energy is transferred to the water to heat it. Another factor working against arm-to-ocean heat transfer is that at the ocean's surface you have the least amount of pressure, reducing the force by which the water pushes toward his arms and reducing the threshold for aforementioned Ledenfrost Effect. As his arms get hotter, all that happens is that the temperature of the steam barrier becomes greater but the mechanical force that prevents more efficient contact heating doesn't go away, and instead you just get hotter steam jetting out from that thin vapor "sleeve" that would envelop his pseudo-submerged arms. Of course you could just keep cranking that temperature dial and start plugging in bigger numbers. So... ocean water isn't just H2O, you're producing steam but also vaporizing the impurities which depend on the body of water but typically include some kind of chloride like MgCl, which is reactive and when superheated as a product of high-temperature saltwater vaporization (such as what happens where lava meets water) can produce Hydrochloric acid... so... Oven would be bathing himself in superheated acid vapor. Keep cranking the temps up and things just get worse, like supercritical water vapor will undergo hydrolysis or decompose into Hydrogen and Oxygen, or just a bevy of weird interactions involving superheated plasma. Anyway yeah the math gets straight-up hostile with this one.

If the Flash moved fast enough towards a lightsaber, the light emitted by the saber would be blueshifted into the x-ray or gamma spectrum.
And a 35 MW x-ray/gamma ray source...is deadly.
Assuming he starts from save distance 50 m and moves to 1 m distance (roughly an arms length), to touch it and his body blocks roughly 1 m²,
how much radiation from the lightsaber does he absorb at a various speeds?
Also considerng radiation with a wavelength of less than 250 nm is ionizing radiation, and a dosis in such radiation is measured in Sievert (Sv).
5 Sv is a deadly radiation dosis for 50% of people after 30 days.
Further assuming the Flash weighs about 70 kg, he should absorb less than 350 J (=5 Sv) in his whole body to have a 50% chance of living after 30 days (radiation sickness will still be horrible though).
So..I did some excel-ing. (this all assumes he is running toward a 35 MW ionizing radiation source)
At 1 m/s (slow walking) he would absorb 4.5 MJ. Toast.
At 10 m/s (Usain Bolt) he would absorb 450 kJ. Instant Death.
At 343 m/s (speed of sound) he would absorb 13 kJ. Almost instant Death.
At 1000 m/s (fast bullets) he would absorb 4.5 kJ. Still Dead.
only at 13000 m/s he would absorb less than 350 J. Maybe Dead.
However, 13 km/s is not nearly enough to blueshift the radiation of the lightsaber into ionizing radiation (for that he would need to move ~90000 km/s) or 1/3 lightspeed.
So... no danger for the Flash to die of radiation sickness.
However, If he approached with 90000 km/s to the lightsaber he would receive (700 µSv). Thats what a normal person receives from natural radiation in a year.
So..probably increased risk of cancer for the Flash.
I see your well thought-out and expertly written scientific examination of an unexplored risk of running towards a Lightsaber and I raise you one Speed Force. There, problem solved, lol.
@@ArcaneEther Dang it. Ruins everything.

@@JustMakeItNazi I did. For each full meter of distance I calculated the size of the surrounding sphere of radiation and how much 1 m² of that would absorb per second. Then traversing the full 49 m can be approximated by adding all of that together (only approximation though, for more accurancy a integration would need to happen, but I didnt wanted to go THAT deep) and dividing the result by the speed the Flash actually runs through.

You seem to be implying that 70°C is double 35°C when in actuality, we can only talk about doubling temperature with Kelvin.
35°C is about 308K, so doubling this would be 616K, or about 343°C. :3
I mean, it is technically "not even doubling."
I agree. also, 70° damage us so much? how do people survive saunas then? or am i missing something obvious here?
@@Monstermoerder1 It depends on the thermal transfer capacity of a medium. Air is a poor thermal conductor. Consider that you can put your hand in an oven (not touching any surface or object) that is basically 350˚F or 177˚C and remove it without any damage. Doing the same in deep fryer oil of the same temperature is a trip to the ER. A dry sauna (no steam) would be more tolerable as evaporation of sweat still occurs (evaporation of water requires a lot of energy). A steamy sauna would cause you to overheat faster as humid air is both a better conductor of heat but it would also inhibit evaporation of sweat. Also, consider that you can walk out side on a below freezing day for short periods without gloves but immerse your hand in water with ice and it gets uncomfortable in seconds.
@@Monstermoerder1 You aren't directly touching the temperature in the sauna for one, two it's spread out over a great distance meaning that the whole temperature change isn't happening that rapidly. In the math Kyle is showing he is meaning that the flesh of your finger actually gets to 70°C, where in a sauna your actual skin never should reach the temperature of the sauna.
This makes it even more spectacular imho: the difference between body temperature and burn temperature is only around 11%
@@tiacho2893 Apparently humans can stand upwards of 400F of completely dry air for minutes on end (assuming the have access to reasonably cool water as you'd sweat enough to dehydrate very quickly).
Personally, I always figured that the type of energy produced by a lightsaber is a sort of plasma that primarily effects more rigid molecular structures of solid matter and has less effect on liquids and even less on gases. Of course, that could be the influence of similar sheilds to those that we see in docking bays that stop air from passing through, but don't stop solid matter.

What about heat transfer rate? If Flash wanted to touch a still igniting lightsaber vs the one that has been on for a minute, the time would be drastically different, right?
I suppose Kyle here made the assumption the ionized plasma inside the respective region of space has already reached thermal equilibrium with the implied heating device.But you are absolutely right,because science...
That's what the timing is all about. Clearly the energy is enough to burn the flash, but it wouldn't have time to transfer enough of it to do damage before the Flash could remove his finger. Kyle just didn't show the math for that here.

Honestly though, the lightsaber has a magnetic field to keep the plasma in place, but wouldn’t the magnetic field also keep the warmth in place so you don’t burn your hand? We are talking about a Sience Fiction lasersword after all.
Magnetic field should only affect plasma and ions though. It can not affect pure energy such as heat given off by radiation
Of course it would, to conserve energy and protect the wielder. The force field recycles 99.99% of that heat energy back into the power required to sustain the light beam. Otherwise you'd run out of battery in like (math math math...) 13.6 seconds.
Same concept as the stillsuit in Dune. Basic conservation.
There are fields that keep the heat contained within the blade. We can't create those fields with modern technology.
Yes we can.
The same technology is currently being used inside fusion reactors to stop the plasma melting the reaction chamber walls.
We've been using magnetic fields to manipulate heat energy for decades now...
🍄
No because heat radiation is literally light photons that have no mass or charge. We can control the ionized plasma in fusion reactors with magnetism to keep it away from the walls enough that it won't melt them but you can't directly control the light emitted as radiation. Also in fusion reactors it's a very tiny amount of ionized gas being fused at once in a tiny flash, then cooling time is allowed.

Clearly The Flash has always been impervious, or at least highly resistant to heat. At even his "low" speeds he can compress the air in front of him like a space craft entering the atmosphere. At his high relativistic speeds he is going so fast he would be blue shifting the light in front of him into higher energies like x-rays and gamma rays. I'm not even going to go into the details of the friction generated by his thighs and other parts rubbing together while he's running. My point is that the flash could definitely touch a lightsaber no math required, but where's the fun in that?

Everyone: *rolls eyes

Yeah but if the flash took a lightsaber by the handle and ran as fast as he could, couldn't he outrun the heat radiating from the realistic lightsaber so he could run with it and touch the blade at the same time?
Although, that would be pretty horrible for whatever was in the flash's path.

Normally yes, but once you add "speed force" to the equation somehow it'll just end up in his personal aura and would just be relative to him and no outside force/law (I'm guessing)

Everyone can touch the hot part of a lightsaber but the thing they used to touch it will be gone
My friend and I think we've figured out the superheated lightsaber problem. We think that the beam is contained within a "ray shield," which is to say the same technology that necessitated using torpedoes instead of lasers when attacking the first Death Star. This would then account for the shape of the blade and why you can't cross saber beams, and also why normal matter like blast doors and arms can be burned through by touching the blade, since normal matter can go through a ray shield. Fixes all the problems.
How about phasing? Could the flash phase trough a light saber?
asking the real questions.
Same thing... He can just run through it. Have you even watched the video?
With same thing I mean that the lightsaber is not an actual blade so he doesn't even have to phase through it- the heat is the dangerous part and since the heat is not harming you when you're fast enough, he just doesn't care
In past videos Kyle dismissed "phasing" as purely fictional.
The phasing part of the Flash's power would require matching quantum frequencies, which is something we actually don't know much about, so it is hard to evaluate it with actual science. Now the comics have said that he is just matching the resonant vibrations of molecules, but that doesn't make sense since they don't stop existing at those frequencies, they actually just absorb more energy. So he can't move through them or anything, they are still there. Most of the comic writers haven't done much real reading about this to even try to explain it in a semi- realistic way. It's just magic essentially.
The speed force could also function like a warp drive (which go above light speed) and contract space in front of him and expand behind meaning mass is irrelevant
Warp drive doesn't go faster than light. It just moves you from one location in space to another quicker than it would take light to travel.
"Going faster than light" implies a speed, and a speed implies travel. But you don't travel with a warp drive. Technically speaking, a warp drive is the slowest method of travel. You get to your destination the quickest, but you don't actually travel anywhere.
@@R3_dacted0 velocity (aka how fast) is calculated using the distance between two points divided by the amount of time it takes to get from one point to the other. As such warping is faster than the speed of light. And warping is still traveling, you're still going from one place to another.
The way I understand it, warp drive isn't moving in the same way. If light could go through warp space it would be going faster than any vessel in it. It is best to think of a warp drive as a shortcut rather than a normal path.

I would imagine that in actual fact the light saber would act in a way to keep the "blade" at it's operating temperature. i.e when it is just idling it would output just enough energy to contract the energy lost to the surroundings, however when it was in contact with the door in the Phantom Menace it would have been losing a large amount of energy to the door (35MW) and therefore would have been operating at max capacity(maybe). This would explain how the Jedi aren't burnt due to the power output of there own lightsabers.
Why has never mentioned the fact, lightsaber not withstanding, that Qui Gon's hand is less than an inch a way from molten metal as he burns through the door. His hands should have been severely burned.
Jon Goff the force?
So basically even holding the lightsaber would be impossible.
No. cus magnets
Yup cuz of the heat
As it turns out... the answer is yes.
At around 2:15, you said that you "refused to put the Flash's top speed beyond the speed of light because physics." I agree, but I'm not sure if you should have.
In one of your videos (I forget which one), I think that you said that the flash had to run "...faster than instantaneous-ness itself..."
Also, according towww.dailydot.com/parsec/how-fast-is-the-flash/,
"In issue #138, Wally gets recruited for a competition of speedsters from infinite dimensions held by some ultra-dimensional beings with some major gambling problems. The losers’ home worlds would be destroyed if they lost. Seeing this entire game as an unnecessary loss of life, the Flash upped the ante.
He bets the alien gamblers that he can beat them in a race back to Earth. Given that they can teleport, it looks like a guaranteed loss because, conceivably, nothing is faster than instant transmission. However, the Flash gets all 5 billion people on the planet to agree to run so that he can borrow their kinetic energy and beats the space overlords in record time."
Love your videos, keep up the good work. You are the best.
This sounds like Dragonball Z. "Share your kinetic energy with me!"
Yes! It's a knetic Genki Dama.
Silly science like that is part of why I'm not a fan of DC. It's just not as believable to me as Marvel tends to be. Marvel has some problems too (obviously) but I feel the explanations behind them are far less ridiculous.
That said, refusal to calculate the Flash's speed at greater than C is due to a couple reasons. One of which is many calculations approach infinite answers. Also, C is the speed of *causality* since the "speed of light" per-se isn't the absolute speed limit (it can be slower in different mediums for example. We can create "photonic booms", where the speed of light through said medium is actually exceeded and you get a flash of light). Causality, on the other hand, is what C stands for in calculations. Which makes it a bit easier to understand the next bit: the nuclear forces that bind our bodies together on the atomic level begin to break down and fail at C. In other words, the atoms can no longer "communicate" with each other, atomic bonds break, whole atoms get ripped apart to elementary particles. In other words, if you were able to achieve the speed of causality, you would basically vanish into a cloud of... you.
@@calvindibartolo2686 The C in E=MCsquared. (sorry, I don't know how to do a superscript for the 2). The C is for Celeritus, which is the greek word for speed. Since light (in a vacuum) has the highest speed possible it best suits the concept of speed. Causality is an inference to this maximum speed, and I don't know if it has been mathematicly proven. If it has then good on you for knowing that. However, as written the C was for Celeritus. A small correction to be sure. But an important distinction
Calvin DiBartolo the speed force literally backs up all the physics like it just lets him run without getting hurt or or run without friction
Hey Kyle, at the end of season 2 of the Walking Dead they say that the zombies would level the house, but I think that the zombies would just squish themselves on it. Would be a neat idea for an episode. Keep in mind that the house was raised off the ground so it looks like the floor is roughly chest hight.
Keep up the great work.
Evidently, yes... See season 7 finale where they literally just make lightsabers because why not
Season 7 really went downhill.

Would the Flash first be electrocuted before burned? After all, his finger would have to pass through an important magnetic field surrounded by an important electric current ?
Considering that you've assumed (some episodes ago) that lightsabers are 'plasma saber', with a huge magnetic field encapsulating some air, then an electric current is running out the magnetic field causing an electron avalanche (remember this episode ?) , so what are you considering as touching a lightsaber? The plasmasaber explanation allows us to neglect the approach problem (radiated heat from 50 m of a lightsaber), but again, what the Flash would be touching.
And then, because electron (from current) would be accelerated by the magnetic field, is this possible that those electrons are relativistic (moving to a speed near lightspeed), and so, could interact with the Flash, electrocuting him before he can touch the plasma region?
Well it's not an assumption on how lightsabers work..reguardless of how much Lucas calls them "laser swords" they are canonically plasma blades contained within a magnetic field that somehow contains the heat of the plasma as well. The flash can go fast enough to break the time barrier so I think he pretty much can touch the Lightsaber all he wants with no problems at all even with the magnetic field in the way..he's also able to vibrate his body fast enough that he can phase through objects on a molecular level..he's been able to do that for ages so that'll probably be a factor too.
I understand what you mean, but just to be sure, how the Flash can break the time barrier? If you want to break the sound barrier, you've got to go faster than the speed of sound, so if you want to break the time barrier, you've got to go faster than light speed? That's exactly where I stop considering the Flash superpower.... Because Physics !
@@marcelsevigny4957 Given Einstein's theory of relativity I suppose that's what has to happen since it has been shown that time slows down the closer to light speed you get...so it leads one to assume that if the Flash runs or spins faster than light speed by x amount then he can time travel or completely break the time barrier..that was the whole point behind the Flashpoint movie after all ..All I know is that it's the Flash running fast enough that he broke the time barrier that usually is behind DC rebooting it's whole universe or retconning something about half the time...there was a time when I was watching an old Superboy cartoon rerun (waaay back in the day) and he (Superboy) spun in place fast enough counterclockwise he went back to the medieval period..then when he was done with his time trip he spun clockwise fast enough to go back to the present...Time really is DC's plaything when they wanna show just how broken you can make a power or character...like that time Superman couldn't save Lois in time so he reversed the spin of the entire planet Earth by shear gravitational speed of his own flight around it and that SOMEHOW wound time back so he could save her..
@@ShinKyuubi Totally agree with you ! Time is toy for superhero !!! Hahaha !!!
Bro the flash can apparently make a lightsaber
Yes he had lightsaber battle with thawne
Honestly I always assumed most of the energy generated was used to contain the plasma into it's shape. Like 80% is used to contain and shape the blade, and the rest is the actual cutting blade. That's how it can be used to block projectiles and lasers, as there's a pretty strong forcefield in place already.
Yeah he could, anyone could, on the handle
But could he grab it by the blade and hurl it at someone?
Yes he could
Hey kyle, if ant man goes sub atomic, can he still hear sound ? Since sound is considered as vibration of air molecules, now if he is less than size of air molecule then it'll be like he is literally in between molecules ( in a compression part of wave or rarefaction part of wave) ?
It doesn't have to be air molecules though, any kind of medium is fine including our own body. So at least anything antman touches or his own bodily functions that have enough energy to vibrate his body will be registered as a sound of somekind.
@LauriNiilo Practically speaking, I think in the human body apart from cranial & ear bones, rest of them are not perfect sound information conductors. ( google glasses ), otherwise we can simply attach ear phones to the arms or elsewhere, can't we !
@Martin Smouter I guess he can detect only if the air molecules particularly in his ears gets shrinked too.
Like anything from that movie is vaguely realistic
He would be moved by the same vibrations that shake the air molecules. And would probably kill him in the process too...
But what if we assumed that the lightsaber crystals can control the force and that they could create some sort of force field that prevented the heat from escaping the saber?
eddox94 finally someone said it ❤️
yes they already do, thats the noise that it makes when coming from the hilt. you can do some more research about it from youtube
Then how would it burn something if there's a force field around it? And if you say it releases the force field when being swung then you have the same problem presented in the video
@@MDCxThePG the force field could let things in, while keeping the saber energy from going out
or, kyle is wrong, plasma cutters reach 25k celsius, the surface of the sun - 5600 celsius, no ones getting sunburn from the heat of plasma cutters.
Lightsabers are ionized plasma contained in a magnetic field
My biggest question is: could The Flash grab onto the (non-realistic) lightsaber long enough to wrench it out of someone's grasp? (He would get to use his super speed to overpower the opponent's grip, since he can apply more force in the same amount of time.) It would be very useful to run around disarming Jedi with your bare (or suited) hands.
Also, just want to point out that according to the TV show, The Flash's suit is specifically designed to be heat-resistant in order to counteract the heat produced by friction with the air at high speeds.
I know this is kinda missing the point of your question, but if the Flash is fast enough to touch lightsabers without damage, he's fast enough to just grab the hilt of the lightsabers without having to worry about the blade. Or, just grab them off the Jedi's belts before they even reach for them.
Grabbing by the blade would be about the friction between his hands and the plasma. It would probably be like grasping at smoke.
Hey Kyle please do a video on all of Gundam's beam weapons( excluding Beamsabers as they are giant lightsabers) as a live action Gundam movie was announced.
...first we'd have to figure out just how the hell Minovsky particles work in the various Gundam universes...at their base though all the beam guns are pretty much charged particle canons...so..the closest thing we have to how that would work is a lightning bolt so we could work from there...Beam Sabers/Daggers/Javelins on the other hand require some way to contain and shape the energy so that's a very different kettle of fish.
The hacksmith actually touched a real lightsaber he built himself
Howdy Kyle! I have a question and a possible idea for another video. In the movie "John Hancock" there is a scene in which John stops a trail in it's tracks to save the guy stuck on the tracks. If we accept super strength scientifically, what would be the actual outcome? If he becomes dense enough to stop several tons if freight, wouldn't he just sink into the ground? And if he was flying and using speed to counter the speed of the train with density, would the steel of the train withstand his cutting force, or would his body slice the train in two like how the mythbusters did with a car. As always love your show, make sure you are getting plenty of rest!
Woudn't the Flash hit more photons/second (but less in total as the lightsaber would have less time to radiate heat) while going towards the lightsaber at near C speeds?
On top of that woudn't he be hit by far less photons as he's running away as fewer would catch up to him at his top relativistically allowed speed?
As a result the flash would feel the heat as he runs towards the lightsaber but running away from it would feel relatively room temperature? If anything this should get a snarky remark out of the flash.
(all this assumnes that the air friction would not have reduced him into a puff of gasses, etc.)
P.S.
LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD laser sword LASER SWORD.
30 km/s isn't a relativistic velocity. But the constance of light speed is the reason for relativistic effects. The light coming at you and the light going away are moving at the same velocity, even when you are moving at a significant velocity. You wouldn't get hit with more photons running toward the light than away from it. It would be the same. Time distorts to keep the relative velocity constant.
So I know this is an older video...but please tell me someone has pointed out at some point that flash has outrun light before...so he can most definitely run faster than lightspeed, due to the speed force making physics its beeotch

@@hadrianmoment3944 thanks buddy!

Great episode Kyle, i just want to say that the fact that you think a "laser sword" would have to irradiate heat all around it to be realistic it's not a given, some pepole in the past thought that making something like a nuclear bomb would be impossible, but as you know with time and devolpment we achived great and terrible things, maybe in the future we are gonna be able to contain heat and light in such a way that making a "laser sword" would be possible.
unless you could encapsulate the "laser sword" in a vacuum, thereby making heat transmission only possible through passive radiation, then I think it might be doable. Otherwise the saber heats the air around it through conduction (physical contact) which then spreads as more and more thermal energy is dumped into the air molecules surrounding it.
Well, it gives off light, so it's already putting out at least one wavelength of radiation that isn't blocked. It would need to have some kind of (completely unknown) field around it to prevent any other spectra of radiation from escaping. If you can do that you might as well make the light-saber invisible while you are at it - by blocking off the visible light as well - in order to make it that much harder to defend against.
However, the imaginary field that's somehow stopping all this radiation from escaping has to at the same time be permeable to matter, otherwise the blade of the light saber would simply hit things and bounce off them without heating them up at all.
Suffice to say that we don't have any force in physics that's even remotely capable of doing all these things at once, and Kyle's show tries to stick with 'known physics' as much as is possible.
@@Vastin - Making the beam invisible might not be the best idea from a safety perspective, considering how devastating of a weapon it is with simple contact.
You are right to a point brother the only thing is that if you do this with say some kind of force shield all you have is a fancy nuclear powdered light bulb. It would be no different than the shell of an incandescent light.
Anyone come back to watch these just for the nostalgia? I miss this format for Kyle, i often find myself coming back here to rewatch his old stuff
The lightsaber actually has a plasma shield which stops the heat from coming out and killing the Jedi or sith and helps it keep its shape…although the force is involved in it there is an explanation at least.
So....this guy predicted it....
:(
A light saber's target would also have to be thought of in means of density, material, reflectivity, as well as speed.
This is because while intensely hot, the photons that make up the blade are traveling at the SOL.
Just watched the final episode of the flash season 7... It had a lightsaber fight XD
Yes, but it will hurt a lot
Back in the 70s it was established that a lightsaber was a form of stellarater. A conical magnetic jar containing high energy hydrogen plasma. That seemed an elegant solution which tied up every aspect of the depictions of lightsabers with a nice bow. I'm not sure why the fandom had moved away from that idea, but it does seem to have done so. Indulging that idea for a moment it would eliminate the heat radiation problem since it is the interaction with solid matter that causes the heat transfer in plasma. If the magnetic field prevents the plasma from interacting directly wirh the medium, then there would be no heat transfer.
wow fr thankyou for this ancient fun fact, I've never considered thought of there being a magnetic field🤔..a type of magnetic field containing high energy plasma makes so much sense too💡

Ok, I have mentioned this before, but your Science fu is week here. Every time you tell us that a Lightsaber must be a Plaza based weapon, you are not using Science. A scientific theory must give way once it’s observed to not fit the situations. You can’t take only one aspect of an observation, in this case, the cutting power of a lightsaber in one scene, and ignore the other aspects of the observation. If the theory does not account for all the observed aspects, it is disproved. In this case, your theory states that a lightsaber is a plasma blade. This theory is proved by you by the heat necessary to cut through the metal door in the Phantom Menace. However, this theory also assumes that the Jedi holding it would burst into flame when igniting the weapon... and the Jedi and those nearby them remain in charbroiled. So the theory is automatically bad, and should be discarded.
How about you use Science. And try to create a theory that agrees with all the observed effects of a lightsaber?
I suggest, again, that Forcefields are a Star Wars technology that is used over and over again. A super sharp, quickly vibrating field of force would cut through a steel door... and create heat as a side effect, by it’s friction.
Yes. I know we have no good physics describing how such a field of force could exist... but it is a theory that allows for all observed effects of a lightsaber.
Science that! Please.
Love the show.
Kinda fits the evolution of the weapon. I had the technical manuals as a kid. The lightsaber was originally way back a vibroblade. Logical evolution to go from vibrating a solid piece of metal to some kind of energy field.
Yeah, it always bugs me when he makes that assumption. Whatever the mechanism at work, it's clearly contained. I would just work with the temperature calculation for the cylinder and assume it doesn't radiate any more energy than a high intensity fluorescent tube of the same size.
If it was going to burn everyone within 30 m it would blind everyone within an even greater distance. Even if it was that hot and only conducted heat by direct contact, the air draft would be a problem every time it was turned on. Clearly, none of those things happen in the movies.
Can we actually "phasing" like The Flash in real life?

I'm just watching these videos. He said the energy output from the lightsaber is about 4mw. Enough to power 1000 homes. Makes a difference. He based the rest of his equations off of that.

The flash has been known to run much much faster than light, its something about the "speedforce" (the thing that gives him his powers) allowing him to defy time and space
Can he go through it though?
Probably. The amount of thermal power transferred to his hand/body as he passed through the lightsaber would be on the same order of magnitude (or maybe a bit more, but whatever) as what's being discussed here, and since the flash can go lightspeed... you get the point. He would have zero problem doing that.
While your body temperatur is around 37°C your skin temperatur (of your hand) is closer to 24°C depending on the person.

Nice idea. (Though you didn't mention the Flash canon idea of a "force field" surrounding him & protecting him from things like air friction.)
Suggested ideas:
• The Flash often pulls a trick where he appears to be in multiple places simultaneously. This is explained by him moving continuously from point to point & back again extremely quickly, while also remaining at each location just long enough for a significant enough amount of light to reflect off off him & through to the eyes/retina/ brain of the viewer. *What the top number of light illusion duplicates that can be produced by The Flash at any given time?* (Spacing them spread out as much as possible, but keeping them close enough so that they can still appear to be a threat. Also considering how fast our eyes/brain system works.)
• Lightsabers - *How could you produce a way of protecting the user from the energy that is being emmitted?* (Note that it wouldn't be all just light or heat either.)
• *Is the Goblin Glider from Spiderman possible with current computer controlled fan blade/jet propulsion systems?*
• *What known Nootropics approach the capabilities of the drugs from the movies Limitless & Lucy?*
• *Which has more acoustic energy, a lightning strike or a Hulk clap?*

You should consider that in the movies where a light saber is used, they don't need to protect themself from simply holding it. There for the handle should offer some protection, regardless of if we understand how.
Yeah. It's a closed radiation circuit. It wouldn't radiate heat in such a way.
It certainly would when you stick it in a big metal door. At that point the door itself is forced to absorb most of that radiation - which it would then quickly re-radiate out into its surroundings, posing almost as much of a hazard as the un-shielded blade itself would.
@@Vastin That awkward moment when you're trying to hold your light saber in, and the black body radiation just gets too hot. At some point it's going to force you to pull out.
I think the air flowing through the lightsaber would be so heated up it probably would expand explosively right in wielders face.
@@diamondflaw That's what she said
Hey, Kyle. Love the show (and this video), but... Hang on, what about that giant thing that produces plasma but it doesn't destroy anything because it is restrained by a giant magnetic field, that thing you've talked about in other episodes of Because Science? Wouldn't that be applied so that the lightsaber (if it were plasma that "cuts" instead of plasma being just a bi-product) only destroyed what it comes into contact with? After all, we have created many things several times hotter than the surface of the sun.
Ps: escape velocity works differently at an angle, you wouldn't fling yourself into outer space... would you?
@@ninjahombrepalito1721 You can in fact propel yourself fast enough horizontally tangent to the earth and still end up in space with enough speed. Also the tokamak or the device you refer to still get's extremely hot. They just use principles of thermodynamics to make sure the heat doesn't get out of the controlled environment they house them in. He talks about this is previous episodes, where he talks about the world's largest temperature gradient by distance. One main reason they don't melt everything is they create a vacuum or "void" around the system so that heat has no medium to flow through.
But you are right it would take more energy or a faster velocity or speed to escape the earth if traveling horizontally rather than if vertically. That being said if Kyle's number of 30 Km/s is held true, and the escape velocity of earth is around 11.186 km/s. It can be easily stated with high confidence that even this would still be sufficient. Mainly as going vertically versus horizontally isn't that large of a change. All it does is change the distance or r in which you are affected by earth's gravity well since earth is a sphere how much it would change would depend largely on the point you are leaving from.
The tokamak does take damage btw. If you look up videos of it when the mag fields collapse the plasma in it is sort of decompressed all at once and leaves burns on the walls of the machine
I wan't gun shrimp as pet :/
It’d be neat if Disney commented (or made cannon) that Jedi constantly use the force to suppress the radiation/thermal energy for the blade, keeping it confined within like an arms reach.
Does that mean that light travels through time? When the Flash can.
Flash can move infinitely fast, light and everything else, except for other speedsters, are completely still to him. He can perceive and react to events in under an attosecond. Light would travel 0.3 nanometers in an attosecond. A nanometer is just 1 billionth of a meter. A hydrogen atom is 0.1 nanometers in length. So yeah, the flash is ridiculously fast, so much faster than pretty much anything else that it isn't even funny.
