[@ProfLeStrange]

RequiemPoete The portals are actually maintained by the Portal gun. Any time you pass through an Aperture Science Material Emancipation Field, the portals are cut off from the signal from the Portal device, thus closing the portals. Also, you can manually disable them us ing the portal gun itself.

Would the earth and moon reach a equilibrium? How much of that air would it take until the moon has an atmospheric equal to that of the earth? Asking because science.

[@IlicSorrentino]

You didn't consider that moon has it's own gravity. It will form a lunar atmosphere and in some millenia the system will be in pressure balance beetween earth and moon probably.

[@PhoenixNL72-DEGA-]

It's not that easy, the moon doesn't have enough gravity to hold the lighter elements in an atmosphere. Also the Moon doesn't have a magnetosphere so like on mars the light elements would be blown away by the solar wind. In short the moon would lose atmosphere to space. At what rate this would happen I don't know and if that rate would be lower or higher then the rate at which the moon would receive air through the portal is also an unknown to me (but I'm sure Kyle could calculate that if he so desires)

[@randomvideosandless9559]

@@PhoenixNL72-DEGA- would'nt the air be forced back to earth by its larger gravity?

[@PhoenixNL72-DEGA-]

@@randomvideosandless9559 Some of it I imagine might land back on earth, especially the heavier elements. But I think the high energy, high speed ionized particles in the solar wind will have a much greater impact then the gravity of Earth. Just like hydrogen and helium in Earths upper atmosphere gets stripped off into space by the solar wind, so will the solar wind strip of the gas particles of the atmosphere around the moon (Which is why helium is scares on earth, Hydrogen bonds with other elements so it becomes to heavy to rise to the top and be blown of, but helium doesn't bond with anything). For the moon much heavier elements would be blown off due to the lack of a magnetosphere and the lower gravity. If the moon would happen to be between the sun and the earth then the gas particles would be blown back onto the earth, but otherwise they would be blown past it in a more or less straight line from the sun. (But that's just my thoughts on it. I'm no expert or anything like that)

[@xenialafleur]

If I had a portal gun, I'd make free energy. I'd have my choice of at least hydro-power and electromagnetic power. Edited to add that Kyle is wrong at the end. Yes, friction would slow things down, but gravity would speed it back up. The object would settle in at a constant speed over time.

[@protorhinocerator142]

It wouldn't need to be fast enough to cause drag. You get a big chunk of steel with teeth on one side, connected to a gear system, connected to a generator. Line it up so the steel bolts to itself, top to bottom. Make a roller guide system to prevent it from spinning out of control. Definite free energy there.

[@SodaDone]

Aka terminal velocity

[@SodaDone]

@@protorhinocerator142 What are you talking about? Every time you move, you experience drag, even if in an almost negligencable amount.

[@protorhinocerator142]

@@SodaDone OK so if there's a tiny insignificant amount of drag, but you're moving 300 tons of lead down an endless conveyor belt, then you get plenty of free energy from the turbine.

[@ProgramViBee]

So essentially, we get a geared rod, and put it through a portal. We weld it on both sides, essentially making a 4d gear. This gear rotates cause of 3D gravity. We then hook that up to a turbine and create energy.

[@simianbarcode3011]

what about a portal to the surface of the sun? or the bottom of the ocean? :)

[@anungodlyamountofcereal6384]

Sam Brickey Well,the gas and plasma of the sun and the sand/rock of the bottom of the sea are all non-portal conductive,only certain materials such as concrete,moon rocks and moon rock related substances,and the specialized walls of the test chambers can sustain portals. That's a facts from the game,not just me.

[@moanguspickard249]

So we make isolated chamber underneath the ocean, put moonstone on it, fire up portal, open the chamber and let water in. Now. How long till the watter fills over?

[@failandia]

it would never ''fills over'', it would simply create a loop, where a salty river just flow down to Ocean again.

[@_kinuha]

Sam Brickey ii

[@fighteer1]

Portal to the Sun: we all die horribly as the super-dense plasma of the solar surface rushes through the portal, turning the Earth's atmosphere into a firestorm thousands of degrees in temperature. It'd take a long, _long_ time for even a trivial amount of the Sun's mass to come through, but all life on Earth would definitely end. The Sun wouldn't even notice. Portal to the bottom of the sea: as noted, you'd get a really high pressure jet of really cold water, plus a lot of very weird (and quite perturbed) organisms and a soup of compressed, decaying organic matter, but it would flow back down to the ocean anyway, making no net difference. And xkcd did the thing about portaling the Earth's oceans to Mars already.

[@wolfinwool]

soooo... according to this intro, the game is called "Portal Gun."

[@toprak3479]

[@lifelesshawk5725]

LifelessHawk game's name is portal, not portal gun.

[@spm974]

Portal Gun 3

[@stynkbate9029]

No, it is called "Portal" and"Portal 2"

[@squirrel9544]

Surely the area of a portal would have to be bigger than a square metre? Like closer to 2 square metres if you look at them seeing as you have to go through horizontally as well as vertically. Like maybe a 2x1 ellipse? That comes out to about 1.6 square metres which would increase the flow rate by 60%

[@TheRonster9319]

Ed F Still not enough but good point

[@Okusar]

Yes, the portals in game are elliptical and tall enough for an adult woman to run through in a nearly fully upright stance (Chell does run with a bit of a hunched over stance). The portals are definitely a bit larger than one square meter; that's easy enough to correct for though, just multiply the results by 1.5 or 1.6.

[@techachech]

I want the cake is a lie: The Cake Is A Lie No I Mean The Real Cake Is A Lie: The confection is a falsehood *PERFECTION*

[@box-7188]

The real question is how did Chell’s arm not get ripped off

[@nattywoo475]

If you stack portals though, the gravity is going to constantly out power the air resistance. So it doesn't matter that you have friction/air resistance, your motion will never stop due to gravity. Right?

[@antonmetrinskiy2714]

hard to see any reason for it to stop, it should probably reach terminal velocity when gravity and air resistance are equal, and infinetly fall this way... every time the object emerges at the top portal it gains next portion of potential energy for free, then consumes it to resist the air and so on, should be perpetual

[@ahlpym]

That was my thought, too. It would stop accelerating at terminal velocity, but it wouldn't slow down. If you built a machine around it to generate energy from the falling object, then the object would be slowed down, but it could be sped back up by just giving gravity time to get it going again. That sounds like perpetual motion to me. Of course, this assumes that the portals can be sustained with less energy than the falling object produces.

[@ChrisGraves1]

My thoughts as well! But here's the butt clencher -- are the portals suspended in space, or suspended by some kind of anti-gravity? If they're suspended in space, the Earth would slowly move away, pulling the object farther to the side and eventually disrupting the bottom portal. If they're suspended by anti-gravity, then wouldn't the anti-gravity have some effect on the potential energy by entering/leaving a portal?

[@ahlpym]

+Chris Graves These portals are usually attached to physical walls, so they should move with the Earth. I don't know how they're attached, specifically, but that's how they work in the game.

[@Renniuq11]

Eventually, the falling object should hit the side of one of the portals, though, since it wouldn't be moving with Earth necessarily. Same idea how if you take a long pendulum and swing it for a while it will slowly rotate as earth does - its disconnected from Earth enough to slowly go out of alignment with the portals.

[@Nerdist]

*The "Kyle is Wrong!" FAQ* (In progress...) 1. Once again, you nerds are more concerned with the last 30 seconds! But let me admit, I think many of you are right about the ceiling/floor portal possibly being a perpetual motion situation, specifically because you are violating the conservation of energy by continuously adding gravitational potential energy for free. However, you WOULD slow down to terminal velocity, and maybe even to ZERO, because once you leave the ceiling portal the gravity of the Earth it leads to would pull you towards it just like the Earth below you (if light goes through, why not gravity?). OR entering a portal could just magically cancel out any gravitational potential energy from a portal you haven't entered. Now we're thinking with portals. 2. Adding CO2 to the atmosphere will air leaks out would still lead to decreased O2 concentration over time and kill us, but given that plants could still use this gas to produce O2, global warming would still be the quicker demise, certainly less than 2,000,000 years. --KH

[@CNNBlackmailSupport]

Nerdist Well, the problem isn't that global warming is worse. It's that "Our carbon production..." is tempered by plants. Leaving that out gets you some big numbers, but isn't the reality. Maybe you should have added "Plants take up X of that, so our burning puts X into the atmosphere."

[@kamenwaticlients]

What if we opened a portal from the sun to earth. How long would it take to cook the planet?

[@redpoint6870]

Nerdist Wouldnt it be easyer to shoot a portal to the sun if destroying the earth with a portal gun is the goal?

[@grugnotice7746]

The sun doesn't have a solid surface.

[@kerim63000]

Nerdist Wait how can you open portals in Moon if sun doesn't have flat surface

[@Egoistic_girl]

After the credits you forgot that there's gravity that accelerates the object towards the bottom portal. And you speak as if the air resistance would slow down the object to a complete stop despite gravity. Plus this is the physics of Portal, not actual physics so since the portal are free to make a maintain they allow for such a thing...

[@protorhinocerator142]

Correct. You don't need to achieve terminal velocity to generate electricity. In fact, I'd prefer to have a large weight, falling slowly, connected to reduction gears. It could be dropping at 5 mph but if there's enough mass, that's a lot of energy.

[@bennupp2142]

I thought the game was called "Portal" not "Portal Guns"

[@Mongward]

A question: wouldn't at some point Moon start forming its own atmosfere with the air taken from Earth? And if this assumption is right (I have no clue if it is), wouldn't the pressure equilise after a while?

[@jimhealis]

The low gravity of the moon would not support sustaining an atmosphere of equal pressure to that on Earth.

[@mikeuhlir562]

I wonder how much of that escaping atmosphere would be recaptured by the Earth's gravity?

[@asiwir2084]

Well the moon is constantly rotating so from time to time the atmosphere would go away from Earth instead of towards it... so... good luck calculating that

[@marcopohl4875]

plus: wouldn't it increase the moons gravity through the portal (because the earths gravity "moves" through the portal as well)?

[@phinxlion]

My thoughts were that it has its momentum, 340 m/s, is directed towards the earth from a tidally locked moon(so rotation doesn't factor-of the moon-), the moons gravity is likely unable to maintain any of it, its pull will have some small change in force but hardly worth noting, whilst the earths gravity is stronger, and the air flow is already directed towards the earth - you'd create a weird system where the moon revolving around the earth is essentially blowing on it.. This leaves me with one other question, what would it do to the weather on earth? would it have an effect or is it insufficient? edit: would this be able to generate thrust? would we loose the moon quicker? Would the earth also be generating thrust? the mechanics of air leaving the earths terrain at 340 m/s confuses me.

[@lordtaco7432]

+Phelanii Not without instantly freezing to death. I can't remember the name, but there is a gas that approaches 0 degrees kelvin. And scientists have shone light through said gas and it slowed down the photons; not to mention it makes the photons act like they are tangible matter with actual weight. Other than that method light has no mass and therefor cannot be condensed. Edit: WAIT! Do you happen to have a black hole in your pocket? Try that, it should condense the light.

[@livedandletdie]

Lord Taco, yes that is true, but you could technically force light to act like matter if you reduced the momentum of the photon, and if you somehow manage to do that while E remains the same, the photon will magically gain mass equal to the square of the lost momentum.

[@ShadowLynx777]

Cristian Nania The gravity never changes. It's just momentum.

[@naniapetru]

ShadowLynx777 I think you'll have to elaborate on that idea. Just one more thing to say, I have: an object can't just stop and float stationary relative to the Earth. It should still fall into the bottom portal thus continuing the cycle. I really hope I didn't miss an important thing and that I am not wrong.

[@Jabooty_Williams]

terminal velocity man the air will limit your max falling speed eventually

[@AMalas]

James yes, but its still a perpetual motion thing, and if you place some turbine in the middle and liquid goes in the portals then thats a perpetual motion machine because the flow will never stop.. Free enrgy pretty much

[@halimceria]

But technically wouldn't an atmosphere start to form on the moon while air leaks through the portal? And it'd stop leaking once the atmosphere of both the earth and the moon would have the same pressure? And since as you explained we're creating more CO2 than hundreds of portals could possibly leak out to the moon, wouldn't this be an amazing way to just simply create an atmosphere on the moon? Or is the moon not massive enough to actually hold an atmosphere? ... SO MANY QUESTIONS!

[@DarthGTB]

Moon's gravity wouldn't be enough to keep it. From afar, it would look like an air-geyser going straight into the void of space. But in case fictional science is able "in the future" to create a really large portal gun, it could fix the atmospheric hell of Venus, making it much more habitable than Mars could ever be.

[@gunslinger9171]

Moon doesn't have enough gravity to keep the atmosphere but it should have some gravity to keep some atmosphere slowing down the flow I would think.

[@DeepFriedBeans23819]

The air would be ejecting faster than the moons escape velocity, the air would go it into space

[@fighteer1]

So would Wheatley and the Space Core -- 340 m/s would send them hurtling out into space as well. In fact, it would have been utterly impossible for Chell to hold onto Wheatley (or hear anything being said), but we can forgive those things for drama's sake.

[@joshward8395]

Naveication the moon has plenty gravity, it just doesn't have a molten core which produces a magnetic field to deflect solar winds, which is what would blow the atmosphere away. Same for earth, if we didn't have a magnetic field, the solar wind would strip our planet of it's atmosphere within years.

Hey Kyle because the portal gun is bridging a gap between to points and space and bringing them close together wouldn't the forces produced by the moon via the portal have other effects? Would the moons forces start disrupting our planetary rotation or orbit? Force sea levels to rise and a host of other issues that could destroy humanity?

[@Wauly]

Ooof that's a doozy

[@LOGISTICGAMERZ]

Jesus Christ, I never thought of this I guess a portal could probably destroy the earth in a day then. Gravity goes RIP. Sea fucks us up RIP Weather system RIP all life as we know it.

[@ShadowLynx777]

BigHeadClan If you put a portal on a wall then on the ceiling then standing in front of the one on the wall, the gravity from the second one wouldn't pull you in. Therefore the moon's gravity wouldn't do shit. Good questions though.

[@BigHeadClan]

Well gravity is a constant force pushing down on you that is generated by the planet, since in your example the portal is already under the effects of earth gravity the forces would be equal (or very close) at either point and thus cancel one another out. (I think). However when you have an entire moons worth of mass, energy and vastly different environmental conditions on the other side of a portal.... Well I'm really interested in what would happen.

[@rmsgrey]

+BigHeadClan I believe ShadowLynx's point is that the gravity coming through the wall-portal from the ceiling portal would pull you toward the wall portal at roughly ten meters per second per second - it's not the force that's important; it's the direction that force would be acting in...

[@yannakaoka1]

About the portal under a portal at the end of the video... wouldn't the object reach terminal velocity? And then stay at this speed? I mean, i would be perpetual motion, because of gravity, and a stable system because of air drag, right?

[@MrOpie8man]

In regards to your perpetual motion portal question, while air friction would slow down the falling object, every time it came out of the top portal gravity would be accelerate the object until it passed through the lower portal. I think it would continue to accelerate until reaching terminal velocity. It would remain at that speed until some other outside force disrupted the balance between air friction and gravity.

[@adelali3612]

I have a question What would happen if you shoot an Orange portal in a box than close the box and throw it inside Blue Portal ? . . Or this imgur.com/a/dr7c1 . . ERROR404 XD

[@PR3TZ3LB0Y]

Adel Ali You just want to crash the universe's brand new gaming pc don't you?

[@adelali3612]

haha ye

[@Wauly]

Assuming the portals are the size from the video game, you would need a large box but also a box that could fit through the portal. So I'm thinking a thick door-shaped box that could go in sideways. I think that it would push itself the way you're pushing it into the portal. So you would push it in and then the box would move sideways from your grip. Your question seems like an error because you're assuming the blue portal makes the inside of the box larger, but it does not.

[@element9224]

Adel Ali the box would appear to hit a wall instead of heading through because the box hits the inside of itself. In the game if an object is blocking the portal as close as it can be then you can't go in the other portal

[@EGeorgev]

If i remember correctly, portals are only sustainable on stationary objects. When you shoot a portal at a movable object (as a box would be) it falls apart,

in assassin's creed 1's gravity was equal to Jupiter's if i remember correctly so if he was a normal human he would have died but he's not a normal human he's one of those superhuman things made by the "gods" of that universe so in a sense the character in the games you play for assassin's creed are all of the same bloodline hence why you can play them, so in short "MAGIC"

[@st1ng2k70]

Go watch game theory

[@henryambrose8607]

You're forgetting that the moon's gravity would stop all the air escaping. For the same reason that Earth's atmosphere doesn't just float off into space, it wouldn't do so on the moon either. Another thing, regarding the ending: yes, the object will encounter air resistance, but it's still falling. Forever. It would hit terminal velocity, but it won't stop. So yes, that is technically perpetual motion. It's just going to fall forever and never land anywhere.

[@PhoenixNL72-DEGA-]

Even earth is loosing light elements like Helium and Hydrogen to space as the rise to the outer layers of our atmosphere. (Helium is actually a rare resource and we are quickly running out of the supplies on earth, which will become a problem in the near future) Also the Moon lacks a magnetic shield so the solar wind will blow an atmosphere away over time. This is the reason why Mars's atmosphere is so thin cause most of it's mass has been eroded into space by the solar wind over the past billions of years. (And the gravity on Mars is substantially higher then the Moon's gravity)

[@shastarobin12]

2:47 I just died from laughter... because science.

[@pickle87100]

I love how you simplify it by not adding the air produced by plants or the fact that literally the portal would free solid as moisture rushed in becoming colder as it speeds up until the portal had a solid block of ice around it

[@AstroEli133]

Air produced by plants uses up the same amount of air, so that wouldn't change anything.

[@2VeeOrNot2Vee]

[@ShAdoWj1995]

Hey. since the moon has gravity, wouldn't the atmosphere collect around the moon and the pressure would equal out?

[@antheosenigma]

The moons gravity is not strong enough to hold air flying out of a portal at Mach 1.

Why

[@erinkarp6317]

But wouldn't the building collapse around the portal and block it, so the air wouldn't be emptying into space.

[@grinningdeathA7x]

Not necessarily no. The air moving over and around it towards the portal would probably erode it over time

[@Duraludon884]

Since the moon portal is pointed directly at the Earth, would the air come back? How much air would be affected by the Earth's gravity and stay a while, before going back through the portal? How much time would that add to the 2 million years?

that final thought should be on the oposite way, if the entrase portal is below the exit portal, anything drop on it will remain on perpetual motion, reaching terminal velocity because gravity will accelerate it even further each time it exits making air friction momentum loss negligible

[@zriiksparks5637]

eman filbert no because that’s not how that works

[@zriiksparks5637]

There’s a maximum size you can reach

[@eviljesus84]

No, because the Universe doesn't have an infinite amount of time to achieve infinite anything (regardless of whether it ends with a Big Crunch, a Big Rip, a Big Freeze, or a Big Slurp; there's also a Big Bounce, but that's basically Crunch+Bang). And even it it did muscles have finite density, so they can only exert a finite amount of force for a given size. And you can't grow them indefinitely, because of the square-cube law, as it pertains to organism (i.e. he'd cook himself from the inside out and implode)

[@3lueoce512]

We’re forgetting a rather large physics issue that arises from opening portals, in that the distance between them determines the energy required to maintain said portal. The most viable theory for portals is that they open a wormhole between the two points. Therefore (correct me if I’m wrong), but I seem to remember seeing somewhere that it would be impossible to maintain a wormhole large enough to fit a human through due to the vast energy requirements - vast being a major understatement.

[@xo_starboyy111]

@nerdist can you do a "what happens if you jump in a portal while the other is stacked on top of it?" How fast would you fall or will you keep uncreasing in speed until friction between air just brought you at a terminal velocity and what would happen if you out them so close together and your body becomes infinit?

[@akshatfendar2811]

what would happen if you put a portal in a portal

[@Wauly]

It would shoot out to where the portal is portal-ing to

[@akshatfendar2811]

Paul Foster ya but where is it portal-ing to

[@davidallen1459]

Scenario A)Well, if you've got two established portals connected, let's say, on the inside and outside of your front door, and you fire a portal shot into the one on the inside, then it should come out the portal on the other side towards whatever is outward from your front door.

[@davidallen1459]

Scenario B)Now, if, on the other hand, you've got a portal on your wall and a portal on your front door, and you take the door off its hinges and start putting it through the portal on your wall, then the door with a portal on it would start to come out of the door that you hold as it goes. The thing is, 1)it would be moving towards the side of the portal on the wall, and might not fit, and 2)the door with a portal coming out of the door with a portal in your hand would itself have a door with a portal coming out of it, which would have a door with a portal coming out of it... it would be interesting to try to make a picture of that without creating any new mass. Things would get real crammed up though.

[@GuyWithAnAmazingHat]

Search for this video: "Crushed between two portals experiment", you may get your answer.

[@Necro743]

Wouldn't most of the air just return to earth anyway? Some would be lost to space (maybe), but the air would be aimed back at earth, that coupled with earths gravity wouldn't it just cycle back into the upper atmosphere?

[@LordGalenYT]

That was my thought as well. Disappointed that he didn't cover that possibility.

[@bokkers11]

Necro743 no earth's gravity isn't strong enough for that. infact a lot of gasses are leaking out of the atmosphere right now and they are much closer to earth.

[@tweetyericsson]

Radiation could be a problem. Mars had an atmosphere and the sun stripped most of it away.

[@Necro743]

directed at earth...

[@Vulcano7965]

Also the best way to reduce velocity relative to earth, you don't aim directly at earth, you point in the retrograde direction of the moons orbit.
