[@YourBoyTrue]

@@ZackShark1 Yeah, that guy jabbed a fucking needle into his eye. He discovered we had color cones. He observed that by pressing on them at different pressures, different spots of color would appear in his vision. He healed with little damage. In another case, he locked himself in a dark chamber with only one small opening. He ended up going blind during that experiment, god knows what it was, and had to lock himself in that chamber for a week.

now we just need one on the portal gun...

[@GatoTomato]

Yep, but it's probably gonna take him some stupidly long time to research on that

[@Ivarius321]

Just look up quantum entanglement and you'll probably have half of the science.

[@GatoTomato]

Actually you are right, but there one thing tho. In portal you can see through the portal which can't really be explained by quantum entanglement since it doesn't really work for light. At least we don't now if it works or not

[@Ivarius321]

The quantum eraser experiment uses quantum entangled light, so it is possible to entangle light. And you should look up the experiment, as it quite literally breaks time and looks like time travel. I recommend the video of PBS spacetime here on KZbin

[@GatoTomato]

Thanks, I'll need to check that out. And there's one thing that would kinda screw over the quantum entanglement tho. The air wouldn't get sucked onto the moon if the two points weren't connected

[@LouSaydus]

rekt

[@ElucarioYEAH]

Henry Bernal You probably learned this, but it only interests you now because videogames.

[@TheInfamousGammer]

ElucarioYEAH true

[@sevenproxies4255]

ElucarioYEAH: But actually learning something means you have to have an interest in it at some point. Whenever you learn something that gets committed to memory and develops understanding of something that you previously didn't understand, it caught your interest. Even though it might've been imperceptible. (for instance: I used to involuntarily learn the lyrics to Britney Spears songs, despite the fact that I hate her music, but on some unconscious level they must have caught my interest somehow) Since the purpose of a school is to teach students, being able to make the students interested in the subject they're being taught should reasonably be considered pretty basic. If a videogame then manages to get someone interested in learning science to the point where they understand something they previously didn't, then you could say that the school failed... Or that video games and certain forms of entertainment can be a superior method of teaching some people... Which would yet again be true in my case, since english is a second language for me, and I learned almost nothing of it in school but mostly from watching films and television-series in english but with subtitles in my native tounge (and reading a shitload of books in english, as well as playing video games in english) The schools need to step up their game, because they are getting beat by the entertainment industry. :P

[@samisarctic]

aAAAA your fursona's so cute

[@The_Sock_]

What if the Gravity Gun is just a badass magnet? Let me elaborate, electrons make up EVERYTHING, and electrons can be manipulated magnetically. It's true that most materials dont interact with everyday magnets but that's only because we dont have a strong enough magnet to interact with the electrons in said objects and materials (like rubber tires) so what if the gravity gun just hyper magnetizes things, charges them with a specific magnetic structure, then briefly reverses the poles on its manipulating armature to repel the object away? SCIENCE!!

[@banjofan647]

Yeah, that was my thought. Gravity Gun is probably just a name

[@amirabudubai2279]

The problem with this is that magnets pull on things differently based on the material. Also if you were to use something like that on a wire loop(electric motors, transformers, inductors which happen to be in almost all electronics) the result would be even more terrifying. It takes 10T to lift a frog, so lets say the gun is 100 times that strong or 1000T; the gun can go from attracting to repealing within a second so that means 2000T change in 1 second; take a transformer that has 1000 windings and .5m2(in reality a transformer has two coils one small one big, but we only need one for an example). This would give a voltage of (1000)(1000)(.5)/1=500,000 volts. And keep in mind that voltage wouldn't drop when when a current is drown from it like most high voltage sources(unless the mag field loses straighten).

[@freezerounds]

It IS called the Zero Point Energy Field Manipulator, so I don't think it's a magnet. It has something to do with zero point energy although i'm not exactly sure how.

[@ChucksSEADnDEAD]

At that point the magnetic field would cause induction on everything, probably causing spontaneous combustions while also ripping the iron from your own red blood cells. I mean, if it's going to pull nonferrous material, ferrous material will certainly be attracted even more.

[@Undy1]

You're all focusing on the wrong thing, the gravity gun is called the Zero Point Energy Field Manipulator because it uses 'zero point energy' as its power source and it MANIPULATES FIELDS. From wiki: In physics, a field is a physical quantity that has a value for each point in space and time. It doesn't have to be the gravitational field either, gravity gun is just a fun name for the thing. It could manipulate the magnetic field, or the strong interaction field (both of which are insanely more strong than gravity). This would also explain why the GG can affect things only in front of it - if it can manipulate the field itself, it doesn't have to create perfectly spherical forces, it could for example change the field vectors on the very edge of an object, essentially aplying force to it. Now that I think of it, using the strong interaction wouldn't be a very good idea - whenever used, the GG would probably just rip apart the atomic bonds holding an object together.

[@esper1003]

PLEASE DO THE PORTAL GUN I MEAN SERIOUSLY IT WOULD BE AMAZING

The implications of the Portal Gun are, indeed... say it with me, now... GOD. DAMNED. TERRIFYING!

[@cockatoo010]

[@LeviathanTamer31]

Cave Johnson himself has already pretty much stated this. In a video that briefly shows a dissected Portal Gun you can see just how broken the physics are in that game. How this one guy managed to make a Wormhole generator by trying to re-innovate Shower Curtains and where you can place them, yet also manages to be the same guy that thought that Piston firing bullets was a good idea, I will never know.

[@Kieran_Davey]

I always imagine that Austin actually does send the script to the video in an e-mail to the people he starts the video with and, while I'm assuming he doesn't, it's still funny to think of the responses he'd get from all of this.

[@PhenixArcher]

there are two ways for this gun to work The first option is mass, like you said. But the second option is something we can't do yet, artificially generate and manipulate a gravity field.

[@thepacific2933]

Gravity field yup a little gravity core

[@derigel9783]

This would still fuck up its suroundings.

[@teoborges3949]

it's only worked because a scavanged Xen Crystal and possible a apperture science prototype.

[@ethoman04]

it's alot more fun to speculate using things we already know than to say "oh well, guess it's something we don't know how to do yet" Just my opinion though

[@3dwaffle77]

bruh even if you manipulate the field you cant control what will it drag to itself so you would be probably sucked into gravity gun and become a yogurt

[@zriiksparks5637]

Couldn't the gravity gun just distort the local space time on the targeted item? It's slightly more feasible then this.

[@thunderlightcreations568]

Exactly what I was thinking.

[@Capt_Dango]

Wouldn't that have the opposite effect of pulling you towards the object? Or if you go the other way it would just make the object start floating.

[@theaveragepro1749]

Does it have to use gravity?

[@flamingaroow59]

seems like it'd pull everything including you to the the thing you targeted it at

[@Strideo1]

Well, it's called "the gravity gun" but, yeah, using something else like an electromagnetic field to move stuff around would be much much more efficient. Of course how the gun doesn't just get ripped from your hand and go flying toward something if it was too heavy is beyond me.

[@ehoeirgoudan6471]

Tranker which is not something to worry about, since the suit never alarms about the radiation. It means that the amount of radiation is not significative

[@Tranker]

Still, considering that Gordon doesn't really wear a helmet, and the radiation sound does get pretty crazy sometimes and how you can die when you are in radioactive water and whatnot, kinda makes you think.

can gamma radiation be affected by gravity? and if so it could be contained and weaponized. maybe this is how the super gravity gun kills people

[@maxxtheender]

Thomas Lowry I wouldn’t doubt that either the US or Russian Governments are working on something like that.

[@corvuscallosum5079]

Gamma rays are high-energy photons, meaning they're basically a type of light, which, as mentioned in the video, assuredly is affected by gravity. Containing it would be wicked hard though, like trying to contain visible light, but worse because it's so high energy.

[@th3airraidsir3n5]

Yes you could theoretically build a gamma ray gun it is the same concept as a microwave you would just need to direct the energy and supercharge the microwave because gamma rays are extremely high energy where as microwaves are relatively low

Okay, two nitpicks. 6:25 The Sun is actually *150* million km away from Earth (or 1 AU) NOT 100 million km. 11:30 You got the weight of the radiator wrong. 0.67m x 0.82m x 0.18m x 6800kg/m3 = 672.4656kg and 672.4656kg x 5% is 33.62626kg ≈ *34kg* , NOT 340kg. This completely undermines any further calculations.

[@imTheMrBEAN]

A xen crystal? Where the hell did you get that from?

[@coffeetext]

imTheMrBEAN Half-Life 2's characters could have used a previously acquired crystal from the border-world, Xen, in which said crystals are abundant, seen in the first game to construct the ZPEF Manipulator long before the events of the game.

[@XG417]

It's pretty much visible on the Gravity Gun's "Barrel". Also, Eli showed Gordon a miniature version of the Anti-Mass Spectrometer, complete with a Xen Crystal Sample, during his brief stay on Black Mesa East. It could be possible it's an excess from the piece he used on the Gravity Gun.

[@golubhimself]

Dylan Hull Well, technically, they peel the skin off your skull and attach themselves to it, and with a beak in the back of their holes they penetrate into the spine and take control of one's nervous system. Or so I read on the wiki.

[@axipixel5811]

The Gravity Gun isn't made by the Universal Union("combine"), it's Black Mesa/human :P

[@notsocrates5979]

Miloš Golubović that still leads to a lot of questions but it still leaves the question: how does it take over your nervous system? Most parasites are small and require a host to live but head tabs are more predatory creatures, yet they use captured bodies to transport themselves, yet the bodies move slower than them 90% of the time

[@axipixel5811]

Dylan Hull If you look at the dead zombie models, there's clearly a large hole in the top of the skull the headcrab breaks through with a "beak". It's also mentioned that Lamarr is "debeaked". The hole in one's torso is a mouth for eating, since the normal mouth is quite obviously covered up. Also, eventually, they mature or produce the Gonarchs that complete the life cycle. The ones seen in Half-Life 2 have been modified for combine use as weapons, which is why they do not mature in to later forms like those even occasionally seen in Black Mesa (Opposing Force)

Dear Austin, I have a request for a SCIENCE! episode on Half-Life 2... again. I mean you did like a dozen episodes on Fallout 4 so...: What's that huge energy ball that is the power source of the Citadel. And by extention... how does it work? Is it plasma? Is it a fusion reactor? How did it get instable after Half Life 2? What are those yellow energy balls that float arround in the "energy pipes?" and that you shoot out of the rilfe? Are thsoe they connected? How is it controlled, since it has to be ultra hot if it is either plasma or a fusion reactor and melts everything it comes in contact with, but Gordon Freeman can just walk just next to it. How do you controll it? Magnetic field? What about the Heat then? How the fuck does it create a super portal to the combine homeworld after explosion? Did it create a dimenstional rift? a pseudo black hole of sorts? a wormhole? Did it even had to do with that? But if not, how was it created then? By the small yellow ones that float up there during the protal was established? yeah right, like those small yellow ones would have enaugh power to establish a interplanetary connection... do they? How can the portal still be active after the main power source of the Citadel blew up? btw. how much power would a plasmaball or a fusion ractor have to have to blow up city 17? And how the fuck did the rocket in Episode 2 disconnect the portals? And of corse how much energy does the core have? Sincerely, Souvereign

Ok I will simplify it: the gravity gun basically destroys the universe every time it is used, eventually resetting reality and everything in it. Talk about a redcon.

Dylan Hull That's going a bit overboard. It's more like a black hole in mass. The universe has plenty of those and it's still here. Earth should be _wrecked_ tho, every time.

But yeah something like that which seems to be able to pick up a sphere that looks like it contains a sphere of anti-matter or a black hole would probably destabilize the universe when used.

[@JyujinPlus]

Well it's not like Xen crystals are magical devices on par with witchcraft, they just... punch holes in the fabric of space time every now and then. Which would explain how Gordon could scan carry that thing and /maybe/ negate his super cancer, but secondarily it might also exponentially increase his super cancer because the Xen Crystals may very well emit radiation all their own which could be harmless to the ranks of the Combine but absolutely feces rating to a Human. Secondarily; the Xen crystals also can't negate the sheer force the gun is excreting. Yes, maybe it could allow for the cone shape the Gravity Gun seems to utilize and probably totally negates power issues, but it cannot negate the sheer force produced in this well of gravity. Gravity is a universal concept, at least in our universe, and even if Gordon could manage to not get cancer, hold the gravity gun, and not suffer negative effects by using it whatsoever; you'll be tearing down every wall you face using it

[@101darklightning]

What's the feasibility of a one way energy shield that so many games use?

[@Gerbs1913]

If you're talking about how it works I would have to imagine it being like a blanket effect that covers a combatant or a ship. Halo for instance where an energy shield will fail after being hit in the same spot repeatedly taking down most of the shield for a time, meaning that it has to cover the entire thing it is generating the shield to protect. As far as feasibility it's not possible now, but there are prototypes for things like active camouflage on tanks. Science wise I have no idea how it works, other than the explanation of "Shut up, don't worry about it, it just works."

[@101darklightning]

I mean the shields you can shoot through, but your enemy can not, one way energy shields, that are present in many different games. Not the regenerating protective aura.

[@bigpenny3509]

Ad victorian

[@Gerbs1913]

Elder Maxson Ah, okay. That I'm not sure on, but more than likely the muzzle of the weapon would probably have to be just outside of the shield to work correctly, so the protective aura would probably work better as it just protects the user or vehicle.

[@dank_crusad3r]

I actually followed you when you started talking physics equations. Turns out my schooling was good for something.

[@ryPish]

Here's where's you're wrong: you assume the Gravity Gun creates a gravity field akin to a star a person or any blob you can reduce to a single point to simply the math. It's actually a switch that opens portals to set of massive objects arranged in such a way to form a linear (conical really) gravity pit right before the gun, allowing you to grab merely the things you point it at and not the entirety of space and time around you. Your science was okay, you just had to think with portals ;)

[@businessburd2071]

yes it is a conical force, but it's not necessarily a portal. The device itself just needs to stabilize itself to prevent the force from going elsewhere. Or this could be a case of misnomer as its called the zero point energy gun by other scientists, so it's more likely a vacuum pulling in objects.

[@kazumablackwing4270]

and if, for whatever reason, the containment failed, it would unleash an extinction level event in the form of a massive singularity...goodbye planet and everything on it

[@AceLeach]

google Zero-Point Energy. I dare you. Seriously it exists in real life and makes sence

[@TheApiedo]

Assassin's creed assasinations from roofs, is this possible to survive just because you break the fall by landing on a different human being?

[@notsocrates5979]

No, you would keep falling unless the person is sitting, if they were standing then it would merely decelerate your fall and in the were sitting, it would break their skull and a few other bones, along with most vital organs

[@lorddelrenarthwipeiii1546]

+Dylan Hull Half right... but explaining this is pretty simple- if you fall on top of someone else from any great height you're both fucked.

[@notsocrates5979]

Lord Delren Arthwipe III yes, but at medium to short distance the landing target is more likely to get more broken bones and crushed organs

[@minerva9104]

Dylan Hull Depending on how you fall on them, a standing person may cushion your fall, but in the end, it is possible to survive the fall if you don't drop from too high

Gravity gun could be a misnomer, since elsewhere its called the zero point energy gun.

[@lefleiner3408]

It is unknown was the "Gravity-Gun" built within Combine Technologies or during Black Mesa. Being more Combin-ish fits the facts and lore, and another interesting fact: DoG carries the same gun in his right hand, that's not all. Dog's legs are Universal Union's Mech legs, like most parts from him. He was constructed both with human and, i think, mostly Combine technology. After "Seven-Hour War", Overworld Army left Earth, leaving a small division on it called "Overwatch", in most cases - Overwatch Transhuman Arm (OTA) These... things, must prove themselves to be a part of the Universal Union (Combine) So most of horrifying synths and mechs are not here. And "DoG" could be one of these things, which was picked up as a scrap after this war. "Resistance" rebuilt it and baym! - made a gravity gun on it's own, sine the first one WAS IN "DOG'S" HAND AS A WEAPON DURING THIS WAR. Did i mentioned the part where "Combine" are actually "Universal Union"... UNIVERSAL... Maybe they have their own laws of Physics in their, so called, "Overworld". Maybe they found a way to filter radiation inside this gun? As well as a knockback force, by sending props fly. Gravity Gun is described by Human Physics, but was that thing built by humans in a first place? Well, Half-Life has so many fucking sick shit, this is the finest of all of them...

[@lefleiner3408]

Well, in short, Gravity Gun could be built out of Human Laws of Physics and within the "UU's laws of Physics"

[@CativaBR]

I didn't want to necropost, but I saw no one replied so, I remember a few years ago reading a cannon Portal comic, Lab Rat was the name I believe, and in one of the pages there was a gravity gun laying in one of the tables, that part of the comic happened before the black mesa incident, so I think its safe to assume the gravity gun doesn't have much to do with the combine, although the design could have been improved with combine tech, that is up to speculation.

[@twolegmike]

The Garg while the combine are from an alternate universe, they are not from an alternate fundamental universe. Which means they can travel through the 5th dimension, and not the 7th.

[@twolegmike]

The Garg combine has the same laws of physics as us, and valve doesn't know how to science good.

[@AppleManiagaming]

it was bult during black mesa considering they used one to put the xen crystal in the anti mass spectrometer. albeit it was much more bulkier back then and likely was made much smaller using combine tech.

What About the infamous "DOUBLE SLIT EXPERIMENT"

[@thegreatnihil7854]

Quantum Physics often disagrees with relativity

[@TheLuketreewalker]

thank you sir

[@bordedup546]

Oh. Can you explain why, to a mere idiot like me, the double slit experiment leads to contradictions between relativity and quantum physics?

[@Ami-Wishes]

Light is a wave and a particle iirc. Also yeah, QP disagrees with Relativity. People are working on stuff to get it all in one big thing

[@bordedup546]

RiokuTheSlayer Wait what does relativity have to do with the composition of light? I though the generally accepted idea was that light is a photon, a discrete packet of electromagnetic energy, that exists as both a wave and particle. It was shown to behave like a wave by the double slit experiment, and a particle due to the photoelectric effect. I just don't see how this means relativity contradicts quantum physics? Does relativity say that light is just a particle, or just a wave but not both?

[@ZRovas117]

One thing I don't understand is, how is it flinging the objects outwards? And why does the momentum not affect you? For every action, there's an equal opposite reaction, ergo, does that mean that the gravity gun absorbs the momentum that should be pushing you back??? Or do I misunderstand the physics of this. Austin. HALP

[@adembroski]

I'm subscribing because someone was actually mostly correct in their use of science to explain fiction. Thank you.

[@iridium9512]

I have something to tell you. It's called "zero point energy manipulator". Gravity gun is just a nickname. It doesn't use gravity at all. Or else it would not be so directional. You just assumed that this works by normal gravity. That would be like saying that gravity plating of starship Enterprise is as heavy as moon. Of course it's not. It's a fictional gravity device. It doesn't follow the same rules you thought you learned at school. Let me give you a better explanation. Zero point energy or vacuum energy is minimum energy that a system can have. That energy is mostly in form of heat or virtual particles. It is the energy that keeps us from reaching temperature of absolute zero. It is also the energy that expand the space. According to science, this energy is either incredibly small or incredibly large. So, let's assume it's the latter. This means that zero point energy manipulator uses this energy force to turn it into motion. So the small vibrations of object become large vibrations in one direction. This is how gravity gun works. You're welcome

[@twolegmike]

Iridium thank you so much. I hate it when people base theories on incorrect knowledge. Knowledge that can be corrected if they'd just watch the first 30 minutes of a half life 2 playthrough.

[@Captain.Mystic]

Meh. Still a fun video.

[@skullzans]

Plus you CAN see the zero point's point on the gravity gun too if you're not seeing it from FPP(First Person Perspective), so that helps. Plus It's so easily notable that this thing stabilizes itself via containment field(Look at its design, it really points to "Containment". There is clearly a very strong invisible barrier keeping it in place and with activation a small "Hole" in the containment is made, as upon usage it suddenly "glows" and only pulls in from the front or close sides, As well as this, dark energy is noted to be a force of expansion, correct? So imagine this, the combine use dark energy to scatter the structure of specified objects to "clean" a person of weapons, but when the gravity gun is hit by it, IT, being a HEAVILY durable containment field and form suddenly takes in dark energy, and the system is put to its limits... The roiling dark energy is trying to escape, and it does every time you use the gun, as the energy from the zero point does as well, but it is far more violent. As you walk with it, you notice the containment field slightly breaking, leaving a small trail of dark energy leaking out(usually into a spire, where the energy containment field and supply are originating from), And every time you open the field tyo pick up a soldier they die instantly, dark energy sparks wreacking havoc on their systems, bearly not breaking them to dust or more... Thats my theory anyhow, and it explains alot, Do feel free to tell me if/where I am wrong.

[@bryanstephenson5639]

BOOOOOOOOOOOOOOOOOOOO!!!!!!!

[@skullzans]

???

[@Flintshadow]

what if it just uses magnetism... like Vanderwhals force and magnetic tunnelling? i mean its only nicknamed the gravity gun

[@TheDubiousSalmon]

It's called the "Zero point energy field manipulator" so it doesn't have to do with magnetism at all

[@Flintshadow]

eh yeah... magnets are safer...

[@notsocrates5979]

That... That is enough magnetism to pull all the plasma out of the damn sun.... And how the hell would it pick up wood and cement? So yes, unless the wood is imbued with iron and the cement is reinforced with iron or another magnetic material, I think magnetism is out of the question. And yes. Plasma is affected by magnetism. They made a machine for containing plasma with magnets. Powerful magnets. But it is not much plasma. I used a lot of periods didn't I?

[@Flintshadow]

everything is magnetic, and you can make a focused beam of magnitism

[@notsocrates5979]

Flint Saraphali the stronger the magnetism, the farther it goes. And it is a bit obvious it isn't using magnetism due to the fact EVERYTHING you suck towards you travels at the same speed, no matter what, so maybe it is just using some kind of funneled vacuum, some kind of auto adjusting vacuum that started shooting and sucking air at the same time once an object gets too close. I have a lot of far fetched ideas.
