The SCIENCE! Behind Half-Life's Gravity Gun 

humongous what

HOW DARE YOU!

IM GOD

Umm. I think I did. Around the point where he started going insane.

13 Piece Bucket me too

2012sandokan doesnt sound too bad

I LOVE IT BEST IDEA OF 2017 - 3000

He won't do the anti vulgarity bullshit. It is fucking ridiculous! Impossible! Holy fuck! FuckFuckFuck Shit fuck god damn mother fucking IMPOSSIBLE! Makes no GOD DAMN SENSE! Any questions?

13 Piece Bucket yes I so do to

Holy shit i didnt know that

@@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.

And died a virgin. He'd rather than a needle in his eye for science than have sex...which technically could have also been done for science

That was the least worst thing he did. Becoming a money cop was egregious. I don’t know if I’m madder at him or Blaise Pascal for abandoning science.

hey, it's for science

No it's not. It's never enough!!

I think it was kinda confirmed in that game or something

Just wait until he hears about the gravity gloves

yes

Yes

wtf this came out like 5 min ago but this comment says its from 12 hours ago. hax

Or, they have a gravity gun that upsets the space time continuum.

MrUberAnarchist could be onto something... but actually it is just as ***** noted; just a Patreon supporter. :)

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

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

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

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 RU-vid

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

IT MAKES NO. GOD. DAMN. SENSE.

Nixx - very true

you know the public school system failed when you look at your comment

rekt

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

ElucarioYEAH true

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

Me two

Except that he always has a single massive oversight in each video that at best screws up his math and at worst completely invalidates his premise.

And that is?

Glampkoo Who are you talking to?

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

and TF2 Teleporters

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.

Do how a portal to the moon wouldn't drain the earth of air

Or move the moon at all

Gravity field yup a little gravity core

This would still fuck up its suroundings.

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

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

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

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

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).

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.

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.

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.

now i know why I love the show so much. its what game theory used to be.

Game Theory: Getting theories wrong since 2015.

still fun to watch, though.

Yea stopped watching them when they started doing Five Nights at Freddie's. It's a shame

DarkshadowXD63 i am annoyed that they are treating their game lab thing as if it were revolutionary when Rooster Teeth have been doing it for years with their Immersionvideos.

Oof

ye

Einstein postulated his ideas in simple form more than a decade before the world became aware of it and he was berated by other scientists for bucking Newton's views.

Exactly what I was thinking.

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.

Does it have to use gravity?

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

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.

next game will be called chemo-life

#shaveheadstosupportthosewhosufferfromsupercancer

So Half Life 3 is kind of Braking Bad with aliens?

TheRealMoch Yeh But what about the hazard suite?

The hazard suit would do an amazing job of keeping out radiation. If only he had A HELMET #SUPERMOUTHCANCER

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

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.

* HEV ALERT * WARNING: HAZARDOUS RADIATION DETECTED. AUTOMATIC COCAINE DISPENSING SYSTEMS ENGAGED. MORPHINE ADMINSTERED. HAVE A VERY "SAFE" DAY.

@ Hey, can I plz beta-test this? I'll sign a waiver if you provide a stocked test kit.

thank you

Thanks

muaic

Thanks... ...nerd

WhiteDraygon thanks 🙏🏾

lol

ya436 Basically, yeah.

I find that offensive! Autistic people still use logic, often to excess, and game theory are just straight up stupid

Albert Einstein had autism funny enough the same form I have Asperger's :)

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

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.

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

Tttttsaaaaaaake meeeeeee onnnnnn

Is gamma radiation in space time? if it is on it, is affected by gravity.

He should just cover hard light in general. Its in so many games, yet makes zero sense.

Remember Symmetra from Overwatch? How the hell did she make something out of light to shoot microwave lasers???

yeah that is a real head scratcher.

Vincent Kenway Maybe she can create a plasma like beam? The real question is how she can make turrets with it.

I did read somewhere that hard light is possible. but it loses energy (light) as fast as it can gather it, but it does form a solid mass. just don't put your hand in it.

Best comment

lol

he doesn't need this is bullshit, as it allows you to teleport up

Sixty Symbols have one.

+HENRIQUE ALMEIDA Are you sure it's not just some sort of worm hole? It uses a god damn black hole as it's ammo.

That's a really god damn good question.

No. No matter what the subject would probably destroy humanity in use. Yay.

Vaults

People get locked inside, go insane, and come out again with some kind of virus or just murder Fucking. Everyone. Vault-Tec! You'll be in an experiment or none of your money back

Let's not get him started on your profil picture..

ok

ok. so insteasd of 34 thousand times the energy of a white dwarf. Its 3 thousand... okay i can see how much of a difference it makes when its still punching gamma rays into your skull and causing supercancer

Loquev so are aerospace engineers. One decimal off and rocket go boom

A magnitude of 10 is a big difference. The energy levels were talking about though it's still quite absurd even if you do reduce it by a magnitude of 10 but thank you for fixing the calculation.

i don't think it matters that much. gordon freeman would probably still get super cancer

Bob Birdsong Plus it's real name is a Zero Point Field Manipulator or something like that. So it doesn't really actually use gravity.

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

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.

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.

@@imTheMrBEAN it can be found in the end of half life 1 when you fight nihilanth and some places when you go to xen,

I'm pretty sure it'll be the same science of the pokeball

+Roma 2056 actually it would be vastly different.

Your 2 dimensional.

Yeah, it would only be similar to the pokeball if you aren't able to look through the portal

A Pokéball rips u Apart entirely and an Portal is like an Shortcut to another point. Portal>Pokéball

Wait. We need an explanation of how the head crabs work. They make you grow claws it looks like, you have a hole in your torso for some reason, and a better question HOW DOES IT TAKE OVER YOUR BODY!

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.

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

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

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)

I gotta admit, it should be good fun to hear Austin talk about that.

Yep

DO THIS AUSTIN

the death note cant be explained by since becuse its created by litlral gods who could of just overwrote anything

james the everything guy shut up we want SCIENCE

Easy. The Gravity Gun is GOD DAMNED TERRIFYING!

The short version. The Gravity Gun is basically a freakin bomb with enough power to turn the Earth into sub atomic particles.

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. And the amount of radiation that thing would release? Yeah... Freeman should be dead, and everyone on the planet should be cooked.

Jeoshua Collins at least you realized about the part of being turned to a cloud of several thousand degree gas from it. 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.

Just don´t use AdBlockers at all xD

have you tried watching porn with ads? That is impossible. Just as you are getting nice and comfy .. *BANG* GETYOUR DICK 17 INCHES BIGGER WITH THIS SECRET TRICK! Thanks, but no. RU-vid is always whitelisted always. And use uBlock origin. AdBlock plus are assholes.

N.Stefanov Well.... Yes I tried. It´s kinda annoying, but it´s definitely possible. Just a few clicks.

N.Stefanov Yeah, I use uBlock Origin too.

Adro Slice When websites stop using ads buy groups that use adware and other Bullshit I will gladly turn my ad blocker off. If they want us to stop using things like that then maybe they should stop doing shady shit. XD As it is I'm perfectly happy blocking 90% of ads and just allowing ads to play on RU-vid. I have no problem supporting the content creators here by me watching a simple ad. Its the least I can do and costs me nothing but a little time.

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."

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.

Ad victorian

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.

Riese Marshall. My brain hurts, not just from the 107 degree heat, but now from your bloody terrifying SCIENCEY stuff that is way beyond me.

Or at least the videos....

He actually does send them, which, I think, he stated in his first "THE SCIENCE BEHIND" video ^^

i will check that, thanks

Followed by Sir Isaac Clarke.

I think the gravity gun contains the souls of every gravity physicist ever to exist, mainly due to the sheer GRAVITY of the concept... Ok I will stop now.

THIS IS WHY YOU DO NOT EYE BALL IT. YOU ARE NOT A COWBOY SHOOTING FROM THE HIP!

Mass Effect 2 reference?

Grim Reaper yep

"Because aliens."

I hate dust

Do I hate mars bars

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

That's like saying God exists because of magic

It's not secretly terrifying, it's GOD. DAMN. TERRIFYING.

CockroachKing13204 according to thumbnail its "secretly terrifying" get ya facts straight, man ^^.

Maybe you should get a sense of humor xD He did say GOD DAMN TERRIFYING in the video so he was quoting correctly. Looks like someone didn't watch the video before mocking people :P

flip jonah not really, im aware to what he was referring, yer just taking too serious what i said, is all.

Thin and shorter than average

Likely skeleton. I say that as a 183 cm 57 kg 19 year old

Jake Thornton Yeah lol i'm not too far off myself. 66kg 180cm. Getting quite a bit of lean muscle recently tho, added a few pounds.

I don't know my height in cm but I'm a 60 kg 11 year old if your wondering I'm 5,4

reinhardt willhelm Try losing a bit of weight before high school. Start lifting ASAP. Within a year, you'll be alpha as fuck.

Cast iron is heavy as fuck. Home radiators can weigh well over 340 kg.

Jake Thornton but the one in the video isn't

The one in the video would weigh about 340kg if you had a real life equivalent.

I agree. I have lifted many radiators and cast iron or not, there is no way that would weigh 340kg. Not disparaging the science in the video, hell knows a lot of effort went into it but that radiator does not weigh that much.

if you do his calculation you get 33.6kg so yeah, i think he forgot to carry a decimal because its essentially an order of magnitude off

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

+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.

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

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

Sunrie *SHUT.*

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

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.

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.

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

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.

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.

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

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

i've been meaning to read up on it, but i've gotten a bit sidetracked.

Aperture Science Austin is thinking in portals

Vincent take all you heard in this vid and multiply it by a million times

That super g-gun would most likely blow up Literally everything

The SCIENCE behind boners kappa Terrifying.

Better: how head crabs work or how antimatter rifles work in Fallout New Vegas

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.

Meh. Still a fun video.

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.

BOOOOOOOOOOOOOOOOOOOO!!!!!!!

???

Portals?

Yeah, if it has that much mass equivalence, it's like you not being able to knock Earth off it's axis by jumping.

Filipe Amaral wait carrying the gravity gun itself would turn you into the center of gravity... Oh god please no...

Multiple xD

Adro Slice I saw the characters surrounding Sun-Austin the first time XD

Oliver Church I think there was one before that ^^

Yeap, when he was talking about mercury there was a clip.

Quantum Physics often disagrees with relativity

thank you sir

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

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

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?

Ethan Metcalf we already have the first one remastered

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

eh yeah... magnets are safer...

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?

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

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.

that could be interesting. unfortunately for poor austin, he's a physicist, biology probably isnt something he knows massive amounts about. I was surprised when he did the stim pack video from fallout.

NotBothered10 well the Geth are machines. no biology involved at all

lol I noticed Bartok's Romanian folk dance in the background. I love classical music, especially Romanian music
