If you liked portal you should try out the half life series. It's made by the same people. Takes place in the same universe as portal. And the main character is an MIT graduate who works with other scientists (and some scrappy security guards) to solve the plot. Start with the first one which is very old and progress through the games. You won't be dissapointed.
The only real problem with a wormhole would be it's distance from each other. Far enough apart there would be no feedback. What's gets really interesting to me, is when you have the portals in front of each other. Making an infinite mirror effect. That's crazy! Talk about radiation overload. If that was to happen. When you put them vertical, it's even better. trolling gravity then. Bucket of water, generator. Done. However. Because of that. Portals won't ever exist. Energy laws are broken. :(
@ImJustSlime marketing. Portal 2 was marketed as a stand alone product. Portal 1 was just a test really, a bonus to the orange box, with those front runners being half life 2 and team fortress 2, but portal 1 got lots of good reception so they continued it.
@FierceMods Nvm, a quick Wikipedia check revealed that black holes can be used for very efficient mass-energy conversions. (btw, type II civilizations can harness that energy)
Still shouldn't be enough to form wormholes, however, and would require a LOT of mass to produce continuous energy to do so.
Looking at space-time like a Non-newtonian fluid, are the physics based applications where less is more? Eventually, you can burst through a barrior of Cornstarch and water with sheer force, but the gentle an appropriate application of energy is better. Please enlighten me, I'm a socioligist, not a miracle worker.
There are formulas, not as complicated as he makes it out to be, course the objects don't follow perfect physical laws either, but basically weight, resistance, collision.. etc.. are all put into a module.
Portal and Portal 2 uses the "source" engine from Valve.
@joebharner1 you have to know the physics behind the object, and code accordingly. He is not saying you are coding physics algorithms
Imagine if when someone fell off a balcony but floated down, or dropped like he was on Jupiter. You obviously need to have a grasp on the physics behind that to create a realistic scenario. Not code the physics, know the physics
@sk8er4ever0101 you have to code the gravity though,the speed one is moving,and the fact that you can't walk trough walls-collision,some of these things are implemented in the modeling programs themselves though,so you don't have to do it yourself,but it's there
@joebharner1 Go search "physics engine" on Wikipedia you dummy.
If not for our understanding of physics, computers wouldn't have existed let alone video games..
And just so you know mister big shot game developer/programmer, if you are a physicist with basic programming skills, big video game companies will be fighting over you.
@arthurthegreat Hello, Captain obvious, nice to meet you! Personally, I was just commenting on how animation is used to eliminate physics calculations in regards to "recoil" on guns.
And no, video games do *not* follow the laws of physics. Most don't even try. You'll have a general "accelerate downwards", vector, and *some* things will follow inertia, but their physics is not Physics. But feel free to argue if you think you know my life's trade better than me =)
@joebharner1 Of course we can’t perfectly simulate all the laws of physics in video games but we are slowly making video games conform more and more to physicals ‘laws’ that make it more realistic to us. I’m sure you would agree that the dynamics in Portal II are slightly more realistic than in the old Mario Brothers. There is much more at play in modern games than acceleration and inertia, like conservation of energy and momentum for instance.
@joebharner1 For example, when you throw a grenade in MWIII and it hits a wall at a certain angle at a certain speed, its momentum, KE and trajectory will change accordingly. When an explosion occurs, the objects around it will move accordingly depending on their distance from the explosion. Classical mechanics are well simulated in modern games. If animators were to simulate all this, it would take modern games like 30 years to come out.
@joebharner1 Torque and center of mass also play a big role. If an object of an arbitrary shape with a center of mass completely on one side is thrown in the air and hits, say the edge of a high building, its spin and speed will change according to what part of the object came in contact with the building and at what speed and rotation.
@joebharner1 At the same time, the object is still affected by ‘the acceleration due to gravity’ in the game and in some games also by air resistance which will change its overall trajectory, speed and rotational motion. The physics involved in modern games are really nontrivial and this is why you have full blown physicists working on them. And as the professor said, there would be lots of differential equations envolved.
@arthurthegreat O_O are you *serious*? All I need to do to get people to write essays is to make a *joke*? You feed the trolls, good sir. You feed the trolls.
Seriously though, do you *really* think you're teaching *me* anything? I've been coding games since 6th grade. I wrote a particle physics version of Tanks in High School- I know how it works.
@joebharner1 Really?! You realize how stupid you are so you try to pass it as a troll?! Pathetic. Next time just refrain from commenting further instead of embarrassing yourself
@arthurthegreat once again, you fail to note the nuances of language and meaning - the same mistake you made when you *began* replying to me. I'm not trolling. I said "You feed the trolls", not that *I* was a troll. This is a waste of both my time and yours: I made a joke that >= 21 people appreciate. So what? You gain nothing by responding to top-comments, you only loose your time. I know how physics work in games, and so do you. No one cares. You mistake me and all of my meanings, so good day.
Phis should see the collapse of the neurotoxin generator. He doesn't seem to be aware that those sequences are pre-rendered animations. If only it were real time that'd be amazing.
PS Valve seems to be working on a real-time physics engine modelling materials on very small scales. The gibs would be created 'on the spot' as it were, and not be one of 5, maybe 6 regular models. I've also seen real-time liquid simulation and metal deformation. Was very impressive. HL3 should be worth the weight.
Teacher: "... as soon as the bridge would've formed connecting this region, it would pinch off again..." I saw watch?v=7ImvlS8PLIo where Lawrence Krauss said that 99,9999...% of mass of particles was created inside them by random appearing and disappearing of some kind of particles (not shure, if he said particles, don't quote me on this) that in average makes the mass the same over a large scale. Mby this is the fenomenon where the same mass is just appearing trough these wormholes that close..
Wormholes wouldn't really be possible, would it? As one of the prof. said it would take a lot of energy. Yeah it would, because the energy required to bend space in that way to link the two locations would be mind bending. I think the only way to link two different locations and be able to pass through would only be to bend space time itself, which I don't think would be possible.
Regarding wormholes related to time travel, Cave Johnson gives us a little insight:
"Alright, this next test may involve trace amounts of time travel. So word of advice: if you meet yourself on the testing track, don't make eye contact. Lab boys tell me that'll wipe out time - entirely. Forward and backward. So do both of yourselves a favor and let that handsome devil go about his business."
I don't understand how a feedback loop would occur in wormholes. If radiation was created by the wormhole, it would take millions of years(assuming its many light years apart) for it to travel from the one opening to the other(since it can't travel faster than light) so wouldn't it take millions of years to feedback and overload the loop?
@12co3dy21 An easy way to illustrate the problem is to imagine a wormhole that has both ends facing each other. In that situation, radiation that goes through one end goes through an infinite loop (sort of like 2 parallel mirrors). That on it's own is not too bad (the mirrors don't explode of course). But now, imagine that one end of the wormhole is lagging by, say, 1 millisecond. In this case, the radiation exiting the wormhole will add to the radiation entering and amplify it.
The portal gun is supposed to follow the principles of quantum tunnelling. The earlier model we know to be known as the aperture science handheld quantum tunnelling device. And some of Schroedinger's work seems to be referenced on one of the walls somewhere.
If computer games were programmed in the manner that Phil talks about them (which is the logical conclusion) then they would be massively more resource heavy than they are.
Things like the recoil of the gun, for instance, are pre-rendered animations that are then used in-game as opposed to the program computing the forces acting upon the firing of the gun.
To be honest I wish games were made with real physics in mind. That would be ridiculously impressive.
@sliver321123 Actually, you are completely wrong about this. Computers have been doing real-time physics for many years now. As such, it does NOT require a large outlay of resources to accomplish. You clearly know NOTHING about computer science as it exists today.
The portal firing animation DOES still use physics because that is simply the way the engine is designed.
Games ARE made with real physics in mind because that is what gamers want. It is really not all that impressive these days.
Jeez, you don't have to be so insulting. I'd like to make it clear that with the firing animation, there are no physics being calculated in terms of recoil, at least in reference to how the gun looks. I know there are physics in games, even flash games are easily able to accomplish this. But these are simple things such as gravity and momentum, not minute animations.
I'm talking about things like sound, air, or other miscellaneous details not being pre-rendered animations. Be calm.
@sliver321123 I meant no insult. Please accept my apology. However, I should point out that gravity and momentum are hardly simple. It is a somewhat complex matter to determine the momentum of any object that passes through a wormhole as the object is effected by gravity only when outside the wormhole. Thus, portals can be very complicated to code as the equations can end up being very difficult to get working correctly.
Apology totally accepted. I can't claim to understand how they've managed to accomplish the portals.
I guess I was just working off of the idea that many things that seem inexorably complex, when solved, are done so by creating the illusion of the aforementioned thing happening when in fact it's just a whole bunch of little things.
I don't know, which I guess is what I'm saying, haha.
@sliver321123 There are generally a lot of phisics in games, for example in racing games there is inertia of the car that's being calculated evert time you change direction of a car that takes into account it's mass and velocity. In fps it's gravity of models jumping and so on. I think you meant to say you wish EVERY action would be calculated with physics equations.
@sliver321123 Well, we can do it today without a huge performance problem, but you would need atleast two, perferably 4 graphic processors, so we can use that extra calculation power to calculate the physics for the effect to happend (which is why it's rather easier to keep this as static data).
The real physics simulators that allows you to play with really big rooms with a lot of things that react on each other, is real slow.
@sliver321123 "Things like the recoil of the gun, for instance, are pre-rendered animations"
To be fair to SixtySymbols. The animation was most likely rendered in a physics engine such as 3DS Max or Maya, before it was 'tidied up' for use in the game, thus it does represent computed graphics, albeit in a reusable animation node.
@sliver321123 Also if you take a basic introduction course in computer graphics you learn how much cheating actually goes on. There is barely anything really physically accurately rendered. Its just "looks close enough to the real thing so that the users won't demand their money back" and it is still very heavy on the hardware.
It isn't fantasy, it's fiction. I know what you mean and I don't mean to nitpick but that sort of thing has always been a little pet peeve of mine. Like when people compare Star Trek to Star Wars as if they're the same thing. Science-fiction vs. fantasy, in my opinion anyways.
And I'd say that Portal is created within the same confines as the real world, just with much more impressive gadgets.
@sliver321123 But the programs in which these animations are made can and do make physics calculations that dictate the rendered output. Albeit, not in real-time.
@sliver321123 do you know what kinda computer it takes to play real physics?.... that's the reason why they don't do that, cuss no one will play the game, there computer would be unable to calculate everything in a single time, so it would have an ineradicable lag to it
these limits wont stay there for ever, but they're the walls that keep use from going to these extents
If, for example, light went into a wormhole and it then collapsed (as Jon Wheeler/Weeler* suggested it would), what would happen to the light? Would it get "popped out" somewhere else in the universe or would it simply cease exict? In the later case, wouldn't that mean that you could make other matter cease to exict by sending it into a wormhole thus decreasing the total matter of the universe?
Now Prof. Copeland says these kind of Wormholes could also open up time travel. That's interesting since the Redemption Turret appears to have knowledge about the future you haven't experienced yet (I won't say any more for those who haven't gotten that far).
@JohnSnowstorm It might not be as bad as it looks. When you record a monitor going at a relatively low frame rate it tends to look even lower since a lot of frames don't match up so get discarded. If you had a game going at 45fps and were recording at 60, you won't capture all 45 of those frames. IF you were recording at 90fps, you would, but not all monitors display that anyway.
This clearly isn't a advertisement. If my taxes went to something like this I would be very happy. There is a great need to make people excited and interested in physics. These video's serve as a great marketing tool for physics and science in general. If you can't see the value in that you need to come down from your ivory tower.

My question: if you accept the possibility that the Universe came into existence 13.7 billions years ago, does Einstein's wormhole still be possible?
Muito Obrigado!

If computer games were programmed in the manner that Phil talks about them (which is the logical conclusion) then they would be massively more resource heavy than they are.
Things like the recoil of the gun, for instance, are pre-rendered animations that are then used in-game as opposed to the program computing the forces acting upon the firing of the gun.
To be honest I wish games were made with real physics in mind. That would be ridiculously impressive.

@sliver321123 Actually, you are completely wrong about this. Computers have been doing real-time physics for many years now. As such, it does NOT require a large outlay of resources to accomplish. You clearly know NOTHING about computer science as it exists today.
The portal firing animation DOES still use physics because that is simply the way the engine is designed.
Games ARE made with real physics in mind because that is what gamers want. It is really not all that impressive these days.

Jeez, you don't have to be so insulting. I'd like to make it clear that with the firing animation, there are no physics being calculated in terms of recoil, at least in reference to how the gun looks. I know there are physics in games, even flash games are easily able to accomplish this. But these are simple things such as gravity and momentum, not minute animations.
I'm talking about things like sound, air, or other miscellaneous details not being pre-rendered animations. Be calm.
sliver321123 3 months ago
@sliver321123 I meant no insult. Please accept my apology. However, I should point out that gravity and momentum are hardly simple. It is a somewhat complex matter to determine the momentum of any object that passes through a wormhole as the object is effected by gravity only when outside the wormhole. Thus, portals can be very complicated to code as the equations can end up being very difficult to get working correctly.

@protoborg
Apology totally accepted. I can't claim to understand how they've managed to accomplish the portals.
I guess I was just working off of the idea that many things that seem inexorably complex, when solved, are done so by creating the illusion of the aforementioned thing happening when in fact it's just a whole bunch of little things.
I don't know, which I guess is what I'm saying, haha.
sliver321123 3 months ago
@sliver321123 There are generally a lot of phisics in games, for example in racing games there is inertia of the car that's being calculated evert time you change direction of a car that takes into account it's mass and velocity. In fps it's gravity of models jumping and so on. I think you meant to say you wish EVERY action would be calculated with physics equations.

sliver321123 1 month ago
@sliver321123 Well, we can do it today without a huge performance problem, but you would need atleast two, perferably 4 graphic processors, so we can use that extra calculation power to calculate the physics for the effect to happend (which is why it's rather easier to keep this as static data).
The real physics simulators that allows you to play with really big rooms with a lot of things that react on each other, is real slow.

@sliver321123 "Things like the recoil of the gun, for instance, are pre-rendered animations"
To be fair to SixtySymbols. The animation was most likely rendered in a physics engine such as 3DS Max or Maya, before it was 'tidied up' for use in the game, thus it does represent computed graphics, albeit in a reusable animation node.

@sliver321123 Also if you take a basic introduction course in computer graphics you learn how much cheating actually goes on. There is barely anything really physically accurately rendered. Its just "looks close enough to the real thing so that the users won't demand their money back" and it is still very heavy on the hardware.

It isn't fantasy, it's fiction. I know what you mean and I don't mean to nitpick but that sort of thing has always been a little pet peeve of mine. Like when people compare Star Trek to Star Wars as if they're the same thing. Science-fiction vs. fantasy, in my opinion anyways.
And I'd say that Portal is created within the same confines as the real world, just with much more impressive gadgets.

@sliver321123 do you know what kinda computer it takes to play real physics?.... that's the reason why they don't do that, cuss no one will play the game, there computer would be unable to calculate everything in a single time, so it would have an ineradicable lag to it
these limits wont stay there for ever, but they're the walls that keep use from going to these extents

If, for example, light went into a wormhole and it then collapsed (as Jon Wheeler/Weeler* suggested it would), what would happen to the light? Would it get "popped out" somewhere else in the universe or would it simply cease exict? In the later case, wouldn't that mean that you could make other matter cease to exict by sending it into a wormhole thus decreasing the total matter of the universe?

MrAMColes 6 months ago
@JohnSnowstorm It might not be as bad as it looks. When you record a monitor going at a relatively low frame rate it tends to look even lower since a lot of frames don't match up so get discarded. If you had a game going at 45fps and were recording at 60, you won't capture all 45 of those frames. IF you were recording at 90fps, you would, but not all monitors display that anyway.
