Two atoms are looking out a plasma window. One atom says, "Hey, I just lost an electron." His friend asks, "Are you sure?" The first atom replies, "Yes, I'm positive."
Why? If you look at the 4 forces described, gravity is actually quite strong. The weak and strong nuclear forces are both extremely short ranged. So they can't influence things over great distances. Gravity and Electromagnetism have infinite ranges using the inverse square law. And the electromagnetic force is far stronger than gravity. But ... there's a problem with electromagnetism. Namely that it has two charges that cancel each other out. And since there's an equal amount of both charges on a macro scale, electromagnetism really doesn't have a huge effect over long distances. But gravity? It may be weak, but there's only one type and it's attractive. So add more mass and the total force increases without limit.
Truly, Gravity sure is a sad character. Last time I talked to him he was living in some slum under Bikini Bottom's trash heap of decaying pineapple tops. Truly sad! I think someone should start a gofundme to help this poor powerless guy :/ ;) :D
The magnetosphere is a force field. It burns up things that fly through it. Although it isn't perfect it is a shield. It stops a lot of things. It repeals it protects it is spherical as well. By my definition we have a giant force field.

@@SavageDarknessGames Good thinking, but magnetism will be reacting to metal objects only, electrostatics would be the answer as it attracts anything and moves anything given the right voltage - in zillions volts probably; however in order to offset's earth production of electrostatics (diaelectrics), you would need a generator the size of earth, and that would be if we knew how earth created it's magnetic (dialectric) fields, because it isn't with a molten core, by definition, past the Currie point that this is ever going to happen.
@@SavageDarknessGames How is magnetism made of particles, it's big claim that we cannot prove, even light it's unproven it's made of particles - photons. (The monadic approach was an invention from Leibnitz where atoms = monades, it's a nice story, science ran with it, but again, it is unproven.) Being linguistically proficient in identifying scientific elements doesn't means those scientific elements 1. do exist 2. are used in the right context anyway.
I read a paper years ago that documented an electrostatic force field. It was inadvertently created by the manufacturing of thin plastic film. The field was generated by the static charge created by the continuous transport of the thin film across a gap between the machines. Workers reported that a bird flying though the gap bounced off an invisible barrier. When studied it was found the effect depended on very narrow set of atmospheric conditions. I wish I could find the paper but it's been over 10 years since I read it.
I really love the way you explain things in a calm tone and at just about the right pace. The animations really help visualize the idea. Keep making such wonderful science videos. Subscribed :)

I like to believe that the electrons that race around the nucleus of my atoms act as a kind of "force field" that repels other electrons in other atoms allowing me to stand on the surface of the earth and interact with things. Is the outer shell of an atom a "thin sheet"? Pretty darn thin I would say. Seems like a natural force field already exists.
He is hardly a scientist now. He has done nothing with anything science in very long time. His faculty page is basically empty for anything he has done in research
I remember a scifi story from either Clarke or Asimov where they created a starship out of the strong and weak nuclear forces from a solid steel hull, but having removed the atoms and left behind the forces. Somehow.
It's funny how usually people rely on animated characters who are cuter than their real person counterpart... But with Up and Atom, it's just the opposite 😂 Good video, thanks for sharing!
I'm sorry, I have to disagree with your version of creating shields/force-fields. I prefer to call them shields as they are mentioned in Star Trek. What makes an object solid is the electron shells within the atom that repel other electrons and atoms from penetrating the solid object. Electron shells are produced by energy-levels within the atom within which the electron exists. Simple calculations tell you that the electron reaches close to light speed (C) as it approaches the nucleus of the atom, hence the reason to use Quantum Mechanics to describe the possible location of the electron within the atom (i.e. you cannot locate something moving that fast (close to C) within the space of an Angstrom (0.1nm). So, how do you create shields? Simple: create an energy level around the ship for charged particles (protons or electrons or charged atoms) to move around the ship close to C. This, of course will require initial *power* to get those particles into their orbits. Together with you will need a highly charged central source or use the ship's surface as polarization as in Star Trek Enterprise. The high speed of these particles with either incinerate any object that comes in contact with the shield, or deflect it due to the particles' large momentum. The shields will be transparent since they will be only a few particles thick, and will only be visible on impact as in ST: TNG. The main problem here is how do you create and maintain an energy level so large? 2 things come to mind: either a fusion reactor, or an matter-antimatter reactor, and a massive object in the middle of the ship that spins so fast that the particles within it are extended to the outside of the ship as shields via centripetal force. If you design it correctly, the mechanism that causes the fusion in the reactor also produces the shield. Even if I knew how to build this and make it work, I would not give it to any government on Earth, especially with the likes of Trump and Putin in power.
12 tone’s channel is super cool I immediately noticed the shirt how neat I haven’t checked out his merch yet but I love it. I’m a biochem student and I love to nerd out about music theory and play bass as a hobby. I always think those two hobbies as very distinct but doing both of them keeps me sane and curious and I couldn’t imagine my life without the arts and science. I wish I knew the story behind his doodles I don’t know why he draws them that way. Does anyone else know?
I think it’s possible what if you get Soliders to lie on paper trace around their body, make lightweight bulletproof metal sheild that goes your body, repeals light, lasers, bullets and keeps you Cool inside, by pressing a button you turn on a magnetic force field, the magnet pushes all magnets/metals away, meaning when bullets come at you, bullets will push away/bounce off you, I think this would be a good idea to try bringing to reality, don’t same magnet forces repelled/push apart, meaning if they find out how to make a bullet levitate they’ll understand how to make bullets bounce off n off not if they use the same armour as bulletproof vest outside your lightweight metal body suit it means you can walk through bullets in your immortality body suit bullet/fire proof, when u walk through fire you a cooling gel pad on the inside keeping the metal from getting to hot, as for lasers if you have the outside like a mirror won’t lasers just bounce back n burn the person firing the laser, the back comes off so you can step inside the suit, what u latch the back back on it over laps the edges/cut to haul the back off.as u step inside before putting your arms through the sleeves you turn on the magnetic force pushing all magnets away so on the negative side meaning you’re on the positive side being the inner side, things can levitate off you, when someone shoots u can just push the bullets down
Your attitude, moves and expression are fabulous. You could be a great teacher for anyone or with anything :P . love for you and for the force field as Star Trek Discovery has shown :D .
Brilliant work Jade :) I love topics like these and for sure all the science fans. Actually I requested a video to you before about physics of the impossible and I'm very happy to see it for real haha :p Thank you very much for your efforts!
Yes, We will XD, because this is our favorite hobby, doing positive stress LOL. And it is said that : It is difficult when I have to and so easy when I want to. And we want it all :) We'll be waiting for your new physics of the impossible vids
Loved this! Such a fantastic explanation for layman like me. I run a tabletop superhero RPG game and Force Field is the most controversial power that a character can have. We're always having armchair-science debates about it. I'll be sure to share this with my group. Oh, and liked and subbed.
What if you use the Earth's atmosphere as an example, like how meteors can disintegrate when they enter the Earth's atmosphere. make the regular air outside seem like space by changing the air inside the "Force Field" but not so much so that it's impossible to be inside. Then use plasma to hold the air inside. This way it'll be like Non-Newtonian Fluids (Oobleck) but instead of hardening when hit, this disintegrate when they enter the "Force Field" at high speeds. This means that you can walk in the "Force Field", but bullets won't be able to get through.
That was very interesting to watch. If I were to guess, among all the impossible things we can see in sci fi, force field doesn't strikes me as the most difficult to make. So, I would say they will probably be a thing in a distant future (or something similar would probably be). There's quiet a few things that I can't buy as being possible (at least within the realm of what we have and know in this world), like a human being going through solid materials or teleportation but Force field doesn't seem too bad.
When you can comprehend why an electron does not just fall into the nucleus, then you can possibly construct a force field. But you have to start at the foundation of the Universe to figure this out.
omg the world would change in so many ways cogito. I wanted to talk about it more in the video but I couldn't think of how to do it without diverging too far from the point. We could live in giant underwater domes because force fields could separate water and air. We could control the weather on land if we lived in giant domes. Entire building, structures and cities could be made out of force field and built much more quickly and cheaply than the way they are built now. They could completely replace concrete, brick and mortar. It would be REVOLUTIONARY!!!
@@upandatomsorry to butt in. Electromagnetic force fields could work against any object so long as you can fit a few conditions. Ionizing any incoming object then using a high grade repulsion field. Or coat any incoming object in iron and use the repulsion field to manipulate the object. Depending on output field strength you could stop any incoming projectile. Aside from turning energy into a solid object i dont think theres any conventional way to make a sci fi force field as far as your materials are concerned. Plasma wouldnt work. Any object that emits a magnetic field could punch right threw, even temporarily. Bypassing it wouldnt be overwhelmingly hard... Most of these solutions are ridiculously high in energy requirements and bypassing them would be fairly easy. A missile fitted with a high power magnetic penetrator tip could slip threw any plasma field. A chromatic finish would render your laser screen... Well pointless. And an armor layer could be bypassed either fast or slow. Any laser could be countered rather easily with a water atomizer sprinkler, and chromatic finishes. Hell even a fog machine would help.
A really high powered laser, one capable of being used as a weapon, isn't going to be neutralised by atomised water. The water would be instantly boiled away. Chromatic surfaces have the same problem... whilst it might take slightly longer, you can melt any material if you can generate enough focused heat. A missile with a magnetic tip can be deflected by other magnets.

reflective (preferably in all wavelength) surfaces can't stop laser either, but are totally able to make them someone elses problem.
Interesting! How about interference of electromagnetic waves? Or gravimetric waves, if that is possible. We can now use acoustic wave interference to lift small objects and stuff. This could be the basis of a tractor/repulsor type beam in my imagination. Which might lead to shaped forcefields?? It just seems a shame if we couldn´t do it. Excellent video, by the way!
Interstellar gas is made up of ionic, atomic and molecular gas as well as larger particles of dust. Interstellar plasma would be the ionic type. A caveat to this is if the non ionic gas is heated high enough or moving fast enough it can also be considered a plasma. (99.9 percent of the sun's mass is considered in the plasma state. That means about 0.1 percent is not a plasma)

I want anti-gravity first. Back to the Future II promised me anti-gravity cars and they are nearly 4 years late. ITS YOUR KIDS MARTY. SOMETHING'S GOTTA BE DONE ABOUT YOUR KIDS
Also why didn't Marty just go "thanks for the advice, doc, when I have my kids I'll remember to raise them better". Why did they have to go to the future?
Back to the future 2 is just a movie and not a prediction of the future, just a guess as to what could happen. people have made hover device but is much larger than hover board used in movie.
create a magnetic field on the outside of the ship and fill it with 1 Eletrostialy charged Sand, dust 2 Cold plasma this provide the effect of a classic force field and would work at stopping lasers and particle beams possibly even missiles and railgun rounds maybe.
I predict the day after Sunday will be Monday so not all predictions are hard. Now if all English speakers change it to something else I will be wrong.
3:594:00 so this is what i had to know , before that i thought i can only use mica (.as best then glass ) to allowing to electrons to pass through it from vaccume tubes
Here I suggest a theoretical possibility of a force field. A very dense accumulation of negative mass could probably act as a force field, I guess. It will be able to repel normal bodies, charged or neutral, as long as they have some mass. As for repelling photons, if the negative mass is modelled as a sphere such that it's radius is lesser than the critical radius of the system=2GM/c^2, where G and c have their usual meanings and M is the magnitude of negative mass of the system, the system could in fact repel photons, and therefore light(it would practically be the exact opposite of a black hole).
An old article I read talked about it, a tape factory (accidentally)invented an electrostatic forcefield. Shooting off high amounts of static force as the rollers moved, pushing things away from them. So... Yes, I believe forcefields can and have existed.
Yep I read that same story. It was in I think North or South Carolina at a Scotch tape factory. Morning moisture in the air also had something to do with it as well as X-Rays being emitted at the point where the raw tape material was being pulled off the roll headed to the cutters.
Also turning on the image of the Enterprise-D (from Star Trek). They had a technology called a holodeck. Which was described as an advanced use of forcefield technology. Computers able to create simulations that people can actually walk into and interact with (no glasses needed).
"But [the electromagnetic force] is completely useless against any insulating material, like rubber or plastic" If that were true, rubber and plastic would fall right through your hand. And not just through your hand, also through the floor. Any piece of rubber and plastic would be in an orbit around the earth's core, eternally falling straight through the earth and back up again, and down again, and up again, etc, without even any friction to slow it down.
Your representation of carbon nanotubes looked alot more like graphene sheets! (I don't blame you, they share alot in common) Also, I believe those nanomaterials are a bit overrated in term of projected properties, but it doesn't hurt to dream! :p
David Weber's Honorverse uses gravity as a shield, sort of. They actually create intense artificial planes of gravity for propulsion of any space-going vessel above the size of a jumbo jet. These fields are so intense that they warp light going through it and tear matter apart. Much weaker fields are used as "sidewalls" to do similar things to photons and gamma rays being used in an offensive manner. They require ridiculously efficient fusion plants to create and the series largely takes place roughly 2000 years ahead of our time, so I don't see us doing that any time soon.
a self-healing Graphine antimatter plain, held in place with a gravity field, like a magnetic field suspends a superconductor locked in a relative position. Or a dimensional vortex that transfers any object or energy to a different point in space, nothing could penetrate because nothing is resisted just relocated to the other side of what is being protected, including light.
1.Electrical discharge 2.Induced current producing opposite magnetic field 3.Graphene balloon 4.Unipolarised high frequency longitudinal waves of ever greater amplitude, with a tiny tail of opposite charge
I’m reminded that some of the first tries at AI made scholars realize they didn’t know quite what intelligence was. When someone achieves a force field, they might find it functionally equivalent to a windowpane. Indeed, I gather a windowpane is quite literally a force field. The bits of mass it is built around are a tiny fraction of its volume, and it can be made both transparent and practically impenetrable. It seems to me the true goal is to conjure windowpanes from nothing and dismiss them at will. Maybe that outlook will spark an idea.
OK. One thing - don't use Michio Kaku as reference. While he has some interesting insights, he is not a real authority on most things. Though there are worse hacks than him. Also plasma (or any matter) in extreme temperatures will become opaque. Although I am speaking of the temperatures that existed before the CMB was released. Also obviously it would depend on wavelength of electromagnetic band that was used in laser. For low and high frequencies you'd need a lot of width to stop the signal. That's why nuclear reactors have couple of meters of concrete to shield us from Gamma rays that it produces. On Microwave and radio spectrum you start to have a problem that the probability function of a photon will mean that it will just "teleport" itself on the other side of the barrier.
In the original Star Trek they always talked about deflectors and a deflector dish. The idea being that the dish would generate an electro magnetic field around the ship to deflect matter while traveling at high speed. The deflectors had the added benefit of being able to deflect or absorb beams from particle weapons. In other Star Trek series they talk about "polarizing the ship's hull" as the means to deflect interstellar dust and particles, and again having the added benefit of deflecting some energy weapons.
Great animations! they are very effective. It is an interesting topic, I wonder what would happen if two force fields collided... I guess they would deflect, so maybe the force field itself is not about stopping objects but rather changing their direction? In that sense maybe gravity points away from the person or object could act as a force field? When I say gravity points I obviously talk from a SciFi point of view, not sure if they would be even possible. Great video, thanks
Just a detail, the electromagnetic force can deflect any normal material, not only what we normally call "magnetic materials". Basically neutrons too have a magnetic "field" , the "neutron magnetic moment". One of the sources of the more powerful magnectic fields what we know of are Neutron Stars. That does not mean that we can turn it into any source of force field, but it's important to remember.
I like to believe that the electrons that race around the nucleus of my atoms act as a kind of "force field" that repels other electrons in other atoms allowing me to stand on the surface of the earth and interact with things. Is the outer shell of an atom a "thin sheet"? Pretty darn thin I would say. Seems like a natural force field already exists.
I see another issue with the layer approach in addition to not being able to make those things yet at the scales needed. To get layers you'll need pass the outer layer, in this example, plasma, though the laser and carbon nanotubes without disrupting or destroying them... I suspect the answer, if even possible, will be enormous amounts of energy. What we really need to find are Dilithium Crystals :)
Great video, as you started i tought about plasma being a candidat as i remambered the different tokomak fusion reactors. They alredy work in a similar way.
What you need is a higgs force field. anything hitting it turns to radiation as it loses it's mass (assuming you can control the higgs and turnit off), then behind it is an electromagnectic to deflect all radiation
It's amazing but electromagnetic fields would also be a huge weakness to the field. It would be insane to blow up a ship through its defensive systems with just the right electromagnetic field
That's why I like how in star trek the forcefields are useless if the enemy has some number. You can imagine they have a technology that almost encrypts the magnetic field so that you can't just disrupt the contained energy with your own field? And yet in sciFi they don't have to explain all that detail to us, just take artistic license and all...
If one of the layers turns out to be impossible/impractical, it could be replaced by something that does something similar; for example, nanobots that disperse and congregate, or have partially-transparent shells (to allow light to pass through) with closing mechanisms, to block way more light. Or, simply, cameras; to relay visual information, of the external world, to the occupants of the force field (even, directly, to their brains) while still blocking lasers.
Earth has force feild its called atmosphere but everybody knows that but the planet are not in the talking list 😐😐😐😞😞😞 (Edit)also thanks for sharing of your smartness 😊😊😊
actually military are investing in a kind of eletromagnetic force field its purpose is not to repulse RPG or missiles but to force them to detonate far from the target.
The force of Electromagnetism has been tested as a type of forcefield. Very high voltage plates separated by a thin insulating barrier. When a metal projectile passes through the first plate and contacts the second it completes the loop, and is liquefied or sublimates. This setup has some major issues for practicality.
David Swenson of 3M Corporation describes an anomaly where workers encountered a strange "invisible wall" in the area under a fast-moving sheet of electrically charged polypropelene film in a factory. This "invisible wall" was strong enough to prevent humans from passing through. A person near this "wall" was unable to turn, and so had to walk backwards to retreat from it. This occurred in late summer in South Carolina, August 1980, in extremely high humidity. Polypropelene (PP) film on 50K ft. rolls 20ft wide was being slit and transferred to multiple smaller spools. The film was taken off the main roll at high speed, flowed upwards 20ft to overhead rollers, passed horizontally 20ft and then downwards to the slitting device, where it was spooled onto shorter rolls. The whole operation formed a cubical shaped tent, with two walls and a ceiling approximately 20ft square. The spools ran at 1000ft/min, or about 10MPH. The PP film had been manufactured with dissimilar surface structure on opposing faces. Contact electrification can occur even in similar materials if the surface textures or micro-structures are significantly different. The generation of a large imbalance of electrical surface-charge during unspooling was therefore not unexpected, and is a common problem in this industry. "Static cling" in the megavolt range! On entering the factory floor and far from the equipment, Mr. Swenson's 200KV/ft handheld electrometer was found to slam to full scale. When he attempted to walk through the corridor formed by the moving film, he was stopped about half way through by an "invisible wall." He could lean all his weight forward but was unable to pass. He observed a fly get pulled into the charged, moving plastic, and speculates that the e-fields might have been strong enough to suck in birds! The production manager did not believe Mr. Swenson's report of the strange phenomena. When they both returned to the factory floor, they found that the "wall" was no longer there. But the production workers had noticed the effect as occurring early in the morning when humidity was lower, so they agreed to try again another day. The second attempt was successful, and early in the morning the field underneath the "tent" was strong enough to raise even the short, curly hair of the production manager. The "invisible wall" effect had returned. He commented that he "didn't know whether to fix it or sell tickets."
Electromagnetic force can be made into a thin field. The strength (density and size) of an electromagnetic field can be manipulated by changing the strength of electricity or magnets. Also you can form almost any shape of field so long as you have the correct structure of magnets and copper wire. Energy consumption is the main issue other than not working on insulators.
I don't need to heat the entire surface. Just where it needs to protect. Which, if it is opaque, would match what we normally see in films. I imagine the magnetic field being used to capture the plasma could be manipulated to increase both heat and density of the plasma at a specific location, for only a brief moment.
I think the first step in answering this question is acknowledging that "force field" is a misnomer for simply "transparent shields". This would save a lot of time. But science fiction often puts another more stringent requirement on force fields: they should be selectively permeable (like a cell membrane). This could be as simple as opening a temporary gap that would allow your shots to go through, though writers' plot devices hide the weakness in this approach.
2:04 "The weak force is the force of radioactive decay. It heats up the Earth's core and is responsible for volcanoes, earthquakes, and continental drift." An interesting way of looking at it!
E-M force-fields could possibly be made using resonances, where the energy is tuned so that there are nulls and very-high-strength planes, which already happens to radio and radar transmissions at various angles, depending on the antenna shape. By using arrays of many tiny transmitters going off in computer-controlled rapid patterns., you could adjust the nulls (low-spots) and high-power points to any shape you want almost instantly by proper array design and enough raw power output. Since you may also be able to tune the frequency and phase of the signal, this could, with enough energy, computer power and speed, and some fast-replaceable material easily turned into a plasma (a spray cloud around the thing to be protected, in effect), the super-hot spots could be adjusted to be directly in front of any attacking thing, both physical (bullets) or energy (laser) and, if hot enough at those spots (in layered resonances one after the other in the way of the attacker would be best), the plasma could be made opaque against any frequency of laser (tuned to exactly negate it like those sound-killing headphones) or literal;ly vaporize a physical object. You would need A LOT OF POWER, of course.
Gravity can easily be used to make a force field, and has been used for just that in the physics-based sandbox game 'Space Engineers'. In the game, one of the science fictional devices you can use in your building is a gravity generator - it is there so you can give a starship a localized 'down', just as we see on countless science fiction shows, like 'Star Trek'. Clever builders have set up ships that have gravity generators with defined fields. One field pulls toward the ship - making a localized 'down' in that direction, while the other field pulls away from the ship - a 'down' away from the ship. By cleverly placing the two directional localized gravity fields, the builders create a space where objects - little rocks, bits of metal - are pulled toward the ship, and just as quickly pulled away. The bits of trash become trapped between two opposing 'downs' that effectively keep the particles within a plane. That plane of bits and bobs becomes a barrier which is deadly to matter. It is a wall of debris that acts like a blender and a surface which blocks and ravages anything it comes into contact with. If it were ever possible to generate gravity - or attractive fields of any type - and then apply this trick, the result would be a plane where matter could be suspended and trapped by forces which render it like a dangerous wall. A force field.
A couple of thoughts.... The strong and weak nuclear forces are carried by particles with mass which limits the distance at which they can have any effect, with the distance determined by the uncertainty principle. So I see two ways to turn these forces into force fields. The first is to manipulate local spacetime or accelerate the force carrying particles to relativistic speeds allowing them to carry the force over larger distances. The second is much more speculative. If force carrying particles somehow had a variable mass, either by having sister particles of varying masses or by some future technology which allows the manipulation of mass somehow, then the forces could act over larger and possibly arbitrary and dialable distances.

I felt so bad for that gravity force
Why? If you look at the 4 forces described, gravity is actually quite strong.
The weak and strong nuclear forces are both extremely short ranged. So they can't influence things over great distances.
Gravity and Electromagnetism have infinite ranges using the inverse square law. And the electromagnetic force is far stronger than gravity. But ... there's a problem with electromagnetism. Namely that it has two charges that cancel each other out. And since there's an equal amount of both charges on a macro scale, electromagnetism really doesn't have a huge effect over long distances.
But gravity? It may be weak, but there's only one type and it's attractive. So add more mass and the total force increases without limit.
Truly, Gravity sure is a sad character. Last time I talked to him he was living in some slum under Bikini Bottom's trash heap of decaying pineapple tops. Truly sad! I think someone should start a gofundme to help this poor powerless guy :/ ;) :D
I did too. Gravity was all like "hey you wanna go for coffee" and she was all "nah I got my own thermos flask thanks". Bro looked beaten.

Correct and if we develope a emf emitter stronger than electromagnets, we could in theroy create a thin field of emf at high particle density.

I love these animations!
Thank you! Means a lot coming from the master of animations :)
Not only the animations !
I read a paper years ago that documented an electrostatic force field. It was inadvertently created by the manufacturing of thin plastic film. The field was generated by the static charge created by the continuous transport of the thin film across a gap between the machines. Workers reported that a bird flying though the gap bounced off an invisible barrier. When studied it was found the effect depended on very narrow set of atmospheric conditions. I wish I could find the paper but it's been over 10 years since I read it.
I really love the way you explain things in a calm tone and at just about the right pace. The animations really help visualize the idea. Keep making such wonderful science videos. Subscribed :)
Try Physics Girl!
but electromagnetic force field already exists. the earth has one. it deflects the majority of sun's radiation.
Magnetic fields require too much power, and modern weapons are electrically neutral
Magnetosphere?
Discoloured Buttflaps It exists, but not the same type of force field as those of science fiction.
As described, it doesn't work as a planar structure
We need to deflect solid objects. She said something about the military using it.(pretty sure the military would not need to deflect uv rays anytime soon.
Props for the clip from Dune
Step Back History Damn! You beat me to it!
I have put at least 2 Dune references in my videos. I don't mess around.
Step Back History I don't know why so many people hate the David Lynch movie. Yes, it's gritty and weird and doesn't follow the book closely, but those rough edges is what's good about it.
Gritty and weird kinda defines Dune... and David Lynch.

Since i have also read it, I can confirm that you prepared this video after reading Physics of the Impossible. Tbh, I really loved your narrating style. You doubled the fun with your excellent visuals and explanation. Keep it up!
Electrified soap bubbles (with floaty nanomaterial)
I like to believe that the electrons that race around the nucleus of my atoms act as a kind of "force field" that repels other electrons in other atoms allowing me to stand on the surface of the earth and interact with things. Is the outer shell of an atom a "thin sheet"? Pretty darn thin I would say. Seems like a natural force field already exists.
Michio Kaku is one of my absolute favorite scientists. Just discovered your channel.......Awesome. (corrected)
:)))
As opposed to one of your relative scientists?
@Toby Henderson yeah, not really a 'scientist' tho, is he... :p
Right. Have you read any of his books
He is hardly a scientist now. He has done nothing with anything science in very long time. His faculty page is basically empty for anything he has done in research
I remember a scifi story from either Clarke or Asimov where they created a starship out of the strong and weak nuclear forces from a solid steel hull, but having removed the atoms and left behind the forces. Somehow.
@@ronruszczyk7935 Thank you! I knew I wasn't imagining it...

I'm sorry, I have to disagree with your version of creating shields/force-fields. I prefer to call them shields as they are mentioned in Star Trek. What makes an object solid is the electron shells within the atom that repel other electrons and atoms from penetrating the solid object. Electron shells are produced by energy-levels within the atom within which the electron exists. Simple calculations tell you that the electron reaches close to light speed (C) as it approaches the nucleus of the atom, hence the reason to use Quantum Mechanics to describe the possible location of the electron within the atom (i.e. you cannot locate something moving that fast (close to C) within the space of an Angstrom (0.1nm).
So, how do you create shields? Simple: create an energy level around the ship for charged particles (protons or electrons or charged atoms) to move around the ship close to C. This, of course will require initial *power* to get those particles into their orbits. Together with you will need a highly charged central source or use the ship's surface as polarization as in Star Trek Enterprise. The high speed of these particles with either incinerate any object that comes in contact with the shield, or deflect it due to the particles' large momentum. The shields will be transparent since they will be only a few particles thick, and will only be visible on impact as in ST: TNG. The main problem here is how do you create and maintain an energy level so large? 2 things come to mind: either a fusion reactor, or an matter-antimatter reactor, and a massive object in the middle of the ship that spins so fast that the particles within it are extended to the outside of the ship as shields via centripetal force. If you design it correctly, the mechanism that causes the fusion in the reactor also produces the shield. Even if I knew how to build this and make it work, I would not give it to any government on Earth, especially with the likes of Trump and Putin in power.
also is that a 12 tone shirt? Love it!
Yes! He's a friend of mine :)
cool i watch that too
@@donaldcarothers832 I watch 12tone VERY often!!!!
Loved the video but the T-Shirt drew me down here...
12 tone’s channel is super cool I immediately noticed the shirt how neat I haven’t checked out his merch yet but I love it. I’m a biochem student and I love to nerd out about music theory and play bass as a hobby. I always think those two hobbies as very distinct but doing both of them keeps me sane and curious and I couldn’t imagine my life without the arts and science. I wish I knew the story behind his doodles I don’t know why he draws them that way. Does anyone else know?
I think it’s possible what if you get Soliders to lie on paper trace around their body, make lightweight bulletproof metal sheild that goes your body, repeals light, lasers, bullets and keeps you Cool inside, by pressing a button you turn on a magnetic force field, the magnet pushes all magnets/metals away, meaning when bullets come at you, bullets will push away/bounce off you, I think this would be a good idea to try bringing to reality, don’t same magnet forces repelled/push apart, meaning if they find out how to make a bullet levitate they’ll understand how to make bullets bounce off n off not if they use the same armour as bulletproof vest outside your lightweight metal body suit it means you can walk through bullets in your immortality body suit bullet/fire proof, when u walk through fire you a cooling gel pad on the inside keeping the metal from getting to hot, as for lasers if you have the outside like a mirror won’t lasers just bounce back n burn the person firing the laser, the back comes off so you can step inside the suit, what u latch the back back on it over laps the edges/cut to haul the back off.as u step inside before putting your arms through the sleeves you turn on the magnetic force pushing all magnets away so on the negative side meaning you’re on the positive side being the inner side, things can levitate off you, when someone shoots u can just push the bullets down

Loved this! Such a fantastic explanation for layman like me. I run a tabletop superhero RPG game and Force Field is the most controversial power that a character can have. We're always having armchair-science debates about it. I'll be sure to share this with my group. Oh, and liked and subbed.

Great work Jade! Really like the idea and well written. :)
Gravity's disappointed expression just made my day.
What if you use the Earth's atmosphere as an example, like how meteors can disintegrate when they enter the Earth's atmosphere. make the regular air outside seem like space by changing the air inside the "Force Field" but not so much so that it's impossible to be inside. Then use plasma to hold the air inside. This way it'll be like Non-Newtonian Fluids (Oobleck) but instead of hardening when hit, this disintegrate when they enter the "Force Field" at high speeds. This means that you can walk in the "Force Field", but bullets won't be able to get through.
bruh just add another layer that only visible from one side
That was very interesting to watch.
If I were to guess, among all the impossible things we can see in sci fi, force field doesn't strikes me as the most difficult to make.
So, I would say they will probably be a thing in a distant future (or something similar would probably be).
There's quiet a few things that I can't buy as being possible (at least within the realm of what we have and know in this world), like a human being going through solid materials or teleportation but Force field doesn't seem too bad.
When you can comprehend why an electron does not just fall into the nucleus, then you can possibly construct a force field. But you have to start at the foundation of the Universe to figure this out.
Awesome video! I wonder how the world would change of we had forcefields. They would be great at preventing disasters or just keeping the rain off :D
omg the world would change in so many ways cogito. I wanted to talk about it more in the video but I couldn't think of how to do it without diverging too far from the point. We could live in giant underwater domes because force fields could separate water and air. We could control the weather on land if we lived in giant domes. Entire building, structures and cities could be made out of force field and built much more quickly and cheaply than the way they are built now. They could completely replace concrete, brick and mortar. It would be REVOLUTIONARY!!!
@@upandatomsorry to butt in. Electromagnetic force fields could work against any object so long as you can fit a few conditions. Ionizing any incoming object then using a high grade repulsion field. Or coat any incoming object in iron and use the repulsion field to manipulate the object. Depending on output field strength you could stop any incoming projectile. Aside from turning energy into a solid object i dont think theres any conventional way to make a sci fi force field as far as your materials are concerned.
Plasma wouldnt work. Any object that emits a magnetic field could punch right threw, even temporarily. Bypassing it wouldnt be overwhelmingly hard... Most of these solutions are ridiculously high in energy requirements and bypassing them would be fairly easy.
A missile fitted with a high power magnetic penetrator tip could slip threw any plasma field. A chromatic finish would render your laser screen... Well pointless. And an armor layer could be bypassed either fast or slow.
Any laser could be countered rather easily with a water atomizer sprinkler, and chromatic finishes. Hell even a fog machine would help.
A really high powered laser, one capable of being used as a weapon, isn't going to be neutralised by atomised water. The water would be instantly boiled away. Chromatic surfaces have the same problem... whilst it might take slightly longer, you can melt any material if you can generate enough focused heat. A missile with a magnetic tip can be deflected by other magnets.
reflective (preferably in all wavelength) surfaces can't stop laser either, but are totally able to make them someone elses problem.
Love this channel. May the force be with you :)
which one? :O
That is a question for George Lucas :)
This is honestly one of the most well-communicated videos on this topic. :)
Interesting! How about interference of electromagnetic waves? Or gravimetric waves, if that is possible. We can now use acoustic wave interference to lift small objects and stuff. This could be the basis of a tractor/repulsor type beam in my imagination. Which might lead to shaped forcefields?? It just seems a shame if we couldn´t do it. Excellent video, by the way!
Love this channel and the host and the animations. Thanks very much!
If interstellar gas is plasma. Then why is is called interstellar gas? Shouldn't it be called interstellar plasma?
For the same reason reduction reactions in chemistry give electrons
Interstellar gas is made up of ionic, atomic and molecular gas as well as larger particles of dust. Interstellar plasma would be the ionic type. A caveat to this is if the non ionic gas is heated high enough or moving fast enough it can also be considered a plasma. (99.9 percent of the sun's mass is considered in the plasma state. That means about 0.1 percent is not a plasma)

That’s not a force. That’s just lust in disguise. More of a diluted emotion than a force.
Excellent video. Intelligent, interesting and great delivery.
Good breakdown on this subject. Thank you.
Here I suggest a theoretical possibility of a force field.
A very dense accumulation of negative mass could probably act as a force field, I guess.
It will be able to repel normal bodies, charged or neutral, as long as they have some mass.
As for repelling photons, if the negative mass is modelled as a sphere such that it's radius is lesser than the critical radius of the system=2GM/c^2, where G and c have their usual meanings and M is the magnitude of negative mass of the system, the system could in fact repel photons, and therefore light(it would practically be the exact opposite of a black hole).
An old article I read talked about it, a tape factory (accidentally)invented an electrostatic forcefield.
Shooting off high amounts of static force as the rollers moved, pushing things away from them.
So... Yes, I believe forcefields can and have existed.
Yep I read that same story. It was in I think North or South Carolina at a Scotch tape factory. Morning moisture in the air also had something to do with it as well as X-Rays being emitted at the point where the raw tape material was being pulled off the roll headed to the cutters.
Also turning on the image of the Enterprise-D (from Star Trek). They had a technology called a holodeck. Which was described as an advanced use of forcefield technology. Computers able to create simulations that people can actually walk into and interact with (no glasses needed).
Could we manipulate the higs field making what ever enters will just pass through you?
"But [the electromagnetic force] is completely useless against any insulating material, like rubber or plastic"
If that were true, rubber and plastic would fall right through your hand.
And not just through your hand, also through the floor. Any piece of rubber and plastic would be in an orbit around the earth's core, eternally falling straight through the earth and back up again, and down again, and up again, etc, without even any friction to slow it down.
I was about to post that. Without the electromagnetic force, matter would fall through itself.
Your representation of carbon nanotubes looked alot more like graphene sheets! (I don't blame you, they share alot in common)
Also, I believe those nanomaterials are a bit overrated in term of projected properties, but it doesn't hurt to dream! :p
Haha yeah when I was reading I didn't really understand how a carbon nanotube can only be 1 atom thick if it loops back around on itself?
How long ago was that design put forward? If it was before 2004 then maybe they said carbon nanotubes because graphene hadn't been isolated yet.
wouldn't the tube surface be just one atom thick, but the material is made from those tubes? i think the material itself isn't 1 atom thick.
I'm guessing graphene wasn't yet a "household name" back in 2017
*a lot
David Weber's Honorverse uses gravity as a shield, sort of. They actually create intense artificial planes of gravity for propulsion of any space-going vessel above the size of a jumbo jet. These fields are so intense that they warp light going through it and tear matter apart. Much weaker fields are used as "sidewalls" to do similar things to photons and gamma rays being used in an offensive manner. They require ridiculously efficient fusion plants to create and the series largely takes place roughly 2000 years ahead of our time, so I don't see us doing that any time soon.
We’ve been making force fields for thousands of years. They’re called walls.
L.A.M.E
Elliot Alderson Keep studying physics, you’ll understand why it’s literally true.
@@donwald3436 I was also wondering why she didn't discuss the electromagnetic force at the quantum scale.
a self-healing Graphine antimatter plain, held in place with a gravity field, like a magnetic field suspends a superconductor locked in a relative position. Or a dimensional vortex that transfers any object or energy to a different point in space, nothing could penetrate because nothing is resisted just relocated to the other side of what is being protected, including light.
Wait a minute...
IS THAT A 12 TONE SHIRT!?
1.Electrical discharge
2.Induced current producing opposite magnetic field
3.Graphene balloon
4.Unipolarised high frequency longitudinal waves of ever greater amplitude, with a tiny tail of opposite charge
I’m reminded that some of the first tries at AI made scholars realize they didn’t know quite what intelligence was. When someone achieves a force field, they might find it functionally equivalent to a windowpane.
Indeed, I gather a windowpane is quite literally a force field. The bits of mass it is built around are a tiny fraction of its volume, and it can be made both transparent and practically impenetrable.
It seems to me the true goal is to conjure windowpanes from nothing and dismiss them at will. Maybe that outlook will spark an idea.
But a mirror on the forth layer, PROBLEM SOLVED
Jade!
Same with Tractor Beams, Yes?

Steve Holliday
OK. One thing - don't use Michio Kaku as reference. While he has some interesting insights, he is not a real authority on most things. Though there are worse hacks than him. Also plasma (or any matter) in extreme temperatures will become opaque. Although I am speaking of the temperatures that existed before the CMB was released. Also obviously it would depend on wavelength of electromagnetic band that was used in laser. For low and high frequencies you'd need a lot of width to stop the signal. That's why nuclear reactors have couple of meters of concrete to shield us from Gamma rays that it produces. On Microwave and radio spectrum you start to have a problem that the probability function of a photon will mean that it will just "teleport" itself on the other side of the barrier.
There is no need to construct a forcefield against laser beams.
Just polish your spaceship to a mirror smooth reflecting finish and you're set.
In the original Star Trek they always talked about deflectors and a deflector dish. The idea being that the dish would generate an electro magnetic field around the ship to deflect matter while traveling at high speed. The deflectors had the added benefit of being able to deflect or absorb beams from particle weapons. In other Star Trek series they talk about "polarizing the ship's hull" as the means to deflect interstellar dust and particles, and again having the added benefit of deflecting some energy weapons.
Great animations! they are very effective. It is an interesting topic, I wonder what would happen if two force fields collided... I guess they would deflect, so maybe the force field itself is not about stopping objects but rather changing their direction? In that sense maybe gravity points away from the person or object could act as a force field? When I say gravity points I obviously talk from a SciFi point of view, not sure if they would be even possible. Great video, thanks
maybe it would be like in dragon ball z with the kamayamaya waves?
Just a detail, the electromagnetic force can deflect any normal material, not only what we normally call "magnetic materials". Basically neutrons too have a magnetic "field" , the "neutron magnetic moment". One of the sources of the more powerful magnectic fields what we know of are Neutron Stars. That does not mean that we can turn it into any source of force field, but it's important to remember.
totally subbing
thank you and welcome!
I like to believe that the electrons that race around the nucleus of my atoms act as a kind of "force field" that repels other electrons in other atoms allowing me to stand on the surface of the earth and interact with things. Is the outer shell of an atom a "thin sheet"? Pretty darn thin I would say. Seems like a natural force field already exists.
Jade is an example of someone who probably could have also been a successful actor, but instead went into science. That's a pretty rare combination.
You remind me of my science teacher from hs. I loved her personality, it made science interesting some how. Keep up the good work!!
Well isn't plasma part of the electromagnetic force?
I thought so
I see another issue with the layer approach in addition to not being able to make those things yet at the scales needed. To get layers you'll need pass the outer layer, in this example, plasma, though the laser and carbon nanotubes without disrupting or destroying them... I suspect the answer, if even possible, will be enormous amounts of energy. What we really need to find are Dilithium Crystals :)
Great video, as you started i tought about plasma being a candidat as i remambered the different tokomak fusion reactors. They alredy work in a similar way.
What you need is a higgs force field. anything hitting it turns to radiation as it loses it's mass (assuming you can control the higgs and turnit off), then behind it is an electromagnectic to deflect all radiation
It's amazing but electromagnetic fields would also be a huge weakness to the field. It would be insane to blow up a ship through its defensive systems with just the right electromagnetic field
That's why I like how in star trek the forcefields are useless if the enemy has some number. You can imagine they have a technology that almost encrypts the magnetic field so that you can't just disrupt the contained energy with your own field? And yet in sciFi they don't have to explain all that detail to us, just take artistic license and all...
I wish force field tech could actually work, and on a personal level-- because that's one of the few things that might really change the gun equation.
A. E. van Vogt's books "the Weapon shops of Ishtar" talk about this subject. He wrote it back in 1951.
I wish you were my teacher 😥
If one of the layers turns out to be impossible/impractical, it could be replaced by something that does something similar; for example, nanobots that disperse and congregate, or have partially-transparent shells (to allow light to pass through) with closing mechanisms, to block way more light. Or, simply, cameras; to relay visual information, of the external world, to the occupants of the force field (even, directly, to their brains) while still blocking lasers.
Earth has force feild its called atmosphere but everybody knows that but the planet are not in the talking list 😐😐😐😞😞😞
(Edit)also thanks for sharing of your smartness 😊😊😊
Wtf you both
@MrZyliaThe earth's atmosphere protects us from most meteors, debris and the coldness from outer space.
@MrZylia Mhm, personally, it reminds me of a natural version of the forcefield from passengers.
if only humans can make something like an atmosphere, forcefield may be come true
actually military are investing in a kind of eletromagnetic force field its purpose is not to repulse RPG or missiles but to force them to detonate far from the target.
We have force fields everywhere.
A shield or armor is a force field, it uses the electrostatic force field
The force of Electromagnetism has been tested as a type of forcefield. Very high voltage plates separated by a thin insulating barrier. When a metal projectile passes through the first plate and contacts the second it completes the loop, and is liquefied or sublimates. This setup has some major issues for practicality.
Jade, you're adorable, I want to give you a hug😊
David Swenson of 3M Corporation describes an anomaly where workers encountered a strange "invisible wall" in the area under a fast-moving sheet of electrically charged polypropelene film in a factory. This "invisible wall" was strong enough to prevent humans from passing through. A person near this "wall" was unable to turn, and so had to walk backwards to retreat from it.
This occurred in late summer in South Carolina, August 1980, in extremely high humidity. Polypropelene (PP) film on 50K ft. rolls 20ft wide was being slit and transferred to multiple smaller spools. The film was taken off the main roll at high speed, flowed upwards 20ft to overhead rollers, passed horizontally 20ft and then downwards to the slitting device, where it was spooled onto shorter rolls. The whole operation formed a cubical shaped tent, with two walls and a ceiling approximately 20ft square. The spools ran at 1000ft/min, or about 10MPH. The PP film had been manufactured with dissimilar surface structure on opposing faces. Contact electrification can occur even in similar materials if the surface textures or micro-structures are significantly different. The generation of a large imbalance of electrical surface-charge during unspooling was therefore not unexpected, and is a common problem in this industry. "Static cling" in the megavolt range!
On entering the factory floor and far from the equipment, Mr. Swenson's 200KV/ft handheld electrometer was found to slam to full scale. When he attempted to walk through the corridor formed by the moving film, he was stopped about half way through by an "invisible wall." He could lean all his weight forward but was unable to pass. He observed a fly get pulled into the charged, moving plastic, and speculates that the e-fields might have been strong enough to suck in birds!
The production manager did not believe Mr. Swenson's report of the strange phenomena. When they both returned to the factory floor, they found that the "wall" was no longer there. But the production workers had noticed the effect as occurring early in the morning when humidity was lower, so they agreed to try again another day. The second attempt was successful, and early in the morning the field underneath the "tent" was strong enough to raise even the short, curly hair of the production manager. The "invisible wall" effect had returned. He commented that he "didn't know whether to fix it or sell tickets."
to cute to pay attention lol
Scientists and highly technical folks will tell you this is not possible until one fine day it arrives with a bang like the iPhone
Wow in your Thumbnail u look ravishing😍😃
Electromagnetic force can be made into a thin field. The strength (density and size) of an electromagnetic field can be manipulated by changing the strength of electricity or magnets. Also you can form almost any shape of field so long as you have the correct structure of magnets and copper wire. Energy consumption is the main issue other than not working on insulators.
I don't need to heat the entire surface. Just where it needs to protect. Which, if it is opaque, would match what we normally see in films. I imagine the magnetic field being used to capture the plasma could be manipulated to increase both heat and density of the plasma at a specific location, for only a brief moment.
Nearest thing to a sci-fi force field I've ever seen is when a Falcon 9 is using it's rocket engine to repulse the heat of re-entry.
I think the first step in answering this question is acknowledging that "force field" is a misnomer for simply "transparent shields". This would save a lot of time. But science fiction often puts another more stringent requirement on force fields: they should be selectively permeable (like a cell membrane). This could be as simple as opening a temporary gap that would allow your shots to go through, though writers' plot devices hide the weakness in this approach.
2:04 "The weak force is the force of radioactive decay. It heats up the Earth's core and is responsible for volcanoes, earthquakes, and continental drift."
An interesting way of looking at it!
E-M force-fields could possibly be made using resonances, where the energy is tuned so that there are nulls and very-high-strength planes, which already happens to radio and radar transmissions at various angles, depending on the antenna shape. By using arrays of many tiny transmitters going off in computer-controlled rapid patterns., you could adjust the nulls (low-spots) and high-power points to any shape you want almost instantly by proper array design and enough raw power output. Since you may also be able to tune the frequency and phase of the signal, this could, with enough energy, computer power and speed, and some fast-replaceable material easily turned into a plasma (a spray cloud around the thing to be protected, in effect), the super-hot spots could be adjusted to be directly in front of any attacking thing, both physical (bullets) or energy (laser) and, if hot enough at those spots (in layered resonances one after the other in the way of the attacker would be best), the plasma could be made opaque against any frequency of laser (tuned to exactly negate it like those sound-killing headphones) or literal;ly vaporize a physical object. You would need A LOT OF POWER, of course.
You are the greatest!!! Able to devulge and explain the most abstruse of physics to us poor mortals. I love it!!
Gravity can easily be used to make a force field, and has been used for just that in the physics-based sandbox game 'Space Engineers'. In the game, one of the science fictional devices you can use in your building is a gravity generator - it is there so you can give a starship a localized 'down', just as we see on countless science fiction shows, like 'Star Trek'.
Clever builders have set up ships that have gravity generators with defined fields. One field pulls toward the ship - making a localized 'down' in that direction, while the other field pulls away from the ship - a 'down' away from the ship. By cleverly placing the two directional localized gravity fields, the builders create a space where objects - little rocks, bits of metal - are pulled toward the ship, and just as quickly pulled away. The bits of trash become trapped between two opposing 'downs' that effectively keep the particles within a plane.
That plane of bits and bobs becomes a barrier which is deadly to matter. It is a wall of debris that acts like a blender and a surface which blocks and ravages anything it comes into contact with.
If it were ever possible to generate gravity - or attractive fields of any type - and then apply this trick, the result would be a plane where matter could be suspended and trapped by forces which render it like a dangerous wall. A force field.
A couple of thoughts....
The strong and weak nuclear forces are carried by particles with mass which limits the distance at which they can have any effect, with the distance determined by the uncertainty principle.
So I see two ways to turn these forces into force fields.
The first is to manipulate local spacetime or accelerate the force carrying particles to relativistic speeds allowing them to carry the force over larger distances.
The second is much more speculative. If force carrying particles somehow had a variable mass, either by having sister particles of varying masses or by some future technology which allows the manipulation of mass somehow, then the forces could act over larger and possibly arbitrary and dialable distances.
