But then that ruins the whole point of "light does not spill out of portals in the game" thing, but it would fit the story line. But maybe GLaDOS only has control of the testing areas, or maybe she can't control the lighting and it was maintained by Aperture.

Or maybe the insane psychopathic computer wasn't fretting over kilowatt-hours and light bulbs

Here's an interesting concept: What would happen if you put a portal on Xen, then went back to earth and put the other portal on earth? Would the two universes collide into a multiverse-rocking explosion? Would it actually work? Would the different laws of physics in the universes change our universe of universe (that's what I call this universe; dont ask why.)?

Im not called timemaster for nothing...

Xen is just another planet in our universe (or, rather, the Half Life Earth's universe). So, assuming that portals can be placed arbitrarily far away while in the same universe, I see no problem.

The entire joke is that Black Mesa's teleportation and Aperture Science's portal tech were working towards the same ends.

but isnt Xen cosidered another universe? For one, the laws of phisics are different in Xen, impling its another universe. Also, aren't the combine from another universe, anyway? The consiquences for mixing universes are already shown in portal storms. And doesnt the Black Mesa teleportation use at least some aspects of string theory? I belive mossman said somthing on that. Im gonna hafta look for that quote.

Now, Xen aside, what would happen if you placed one portal in one universe and another in a different one? Would any of the previous things descibed happen? Or, would somthing entirely different happen?

Gravity is lower there. Gravity is also lower on the moon. Reductio ad absurdum.

Little is revealed of the Combine's rule outside of Earth, but dialogue in Half-Life 2 states that they control worlds in different dimensions and inhabited with a range of species.

We're closing in on a reliable local teleport technology, something the Combine still hasn't mastered. Eli thinks their models are string-based ...

No clue. We have very little knowledge of trans-dimensional mechanics in the HL universe.

Actually there are different laws of physics because the gravity there only pulls DOWN, not all around a planetary body.

Or did you forget the earth is round? JK.

I personally think that our universe would combine with the other universerse: kinda like universal offspring (ew) and life as we know it would cease to exist.

As in: We would all die.

wikipedia defines the universe as everything that physically exists. So, you're implying the combine are not physically existing? There's no other universe. UNI-verse. ONE.

Duff brings up an interesting point since the lemma that it only exists if it's on Wikipedia brings about some interesting self-reference loops here.

My guess is it will cause another Resonance Cascade (but in the Aperture facility this time) with a bunch of Portal Storms.

In my opinion, if you put a portal in another universe(Assuming that there is), nothing would happen, unless some great big universe combining thing fell through the portal.

Now we're thinking with the Multiverse.

Trust me, you dont want to get in a theroretical physics battle with me.

Now, i'd think that, considering M-theory (http://en.wikipedia.org/wiki/M_theory), since the universes in the multiverse's perspective, are Membranes, creating a hole in one membrane that links to another membrane would most likely combine the two, or perhaps if the laws of physics in one universe were different just the right way (actuallly it would be the most likely senario), the portal gun wouldnt even work at all. Also, you could fall completely apart in another universe because carbon could highly unstable in that universe's specific laws of physics, but that's beside the point.

To quote that article; hypothetical.

I don't see what the big mystery is here. Why do we need all these stupid hypothetical "other universes"? The universe is endless. It's just SPACE. That's all it is. NOTHINGNESS filled by physically existing objects. NOTHINGNESS can go on forever, you don't need multiple nothingnesses. It's just NOTHING. That's what outer space is, nothing. That's why it's called space.

But the question is: Using the hl2 universe, where other univeres do exist, as implyed by the game, what would happen if you placed one portal in one universe, and one in another?

Also: We dont need these universes, but if they exist, they are there! We don't pick and choose whats right about our multiverse, it just is there. Hey, it is kinda useless, but if its true, wouldn't it matter? Plus, what if there's a buch of combine sodiers just waiting to destroy some new universe, or maybe a room filled with cake, on the other side of that interuniversal line? Pretty important now, eh?

I don't know who wrote "alternate dimension" in wikipedia for it, but they should be slapped for pretending to be an HL fan. it's just a collection of asteroids in the middle of space. That's it. It's a collection of asteroids that intelligent life forms inhabit.

Let's look at it this way, Black Mesa created a teleporter, amirite? It teleports people to other places in the universe. NOT to some multi-verse bullshit. It's point A to point B, not point A1 to point B2. Gordon uses that teleporter to get to Xen. If Xen WAS in some other redicoulus universe, then that would mean the teleporter goes to alternate realities without warning. But this would be IMPOSSIBLE, seeing as the teleports are used frequently in HL2 without confusing any timelines.

But the combine did not all come from Xen, did they? They must have come from somewhere else.And, putting some 2+2 together, the Black mesa Teleporter, apperently using string models, caused the portals storms, meaning that the combine are not from our universe. And also, how do you explain the different laws of physics in Xen? The gravity is all down, and the gravity is actually stronger than it should be.

That makes absolutely no sense, you're saying just because they teleported to Earth means they're from another universe. That's retarded. Xen and the combine homeworld are most likely part of the same universe, the ONE universe, the ONLY universe. Would you leave infinity to go to another infinity just to capture a bunch of asteroids? Probably not.

As for the gravity on Xen, a large cluster of asteroids will have a similar gravitational effect as a planet. Adding the gravitational pulls of the small "planetoids" together = more gravity. Common sense.

The causation you're inferring here is completely unjustified.

The laws of physics are not different. Gravity isn't "stronger than it should be". The gravity is just caused by something that isn't a part of the game. Think about Cloud City in Star Wars. It's kind of like the Xen floating things that you went to in Half Life. It was still in the gravity well of Bespin, which gave the city its gravity, but when you were on the city, you didn't necessarily see Bespin the whole time.

You're making up premises and then using them to jump to conclusions without justifying them.

I am basically only skimming the last 2 pages. I hate posting in this thread.

Duff, collar that dog for a sec. It is explained by scientists in HL1, and perhaps even more importantly by Gman at the end of HL1, that Xen is a "border" dimension, which I think can be interpreted as the border between various dimensions, or the border between existance and nonexistance.

I disagree with Hober that Xen has a lower gravity because it has less mass or some other easily explained away explaination. I also completely disagree that Xen is "just some asteroids floating in space"; you're forgetting some of the skyboxes used there, which looked like microscope slides, inferring an inner-space concept that physical size does not determine importance in this dimension. I do think that physics, to some degree, simply are different there. Maybe not 100% different than what we know, but different enough that things like gravity and mass and inertia react differently than what we know them to do here in our dimension. If the Xen portion of HL1 had as powerful of an engine as Source when it was created, I would imagine that there would be more going on than just lowgrav.

I think the "one Portal in one dimension/universe, the other Portal in a different dimension/universe" question either will be answered in Episode 3 with the Borealis, or it has already been answered in Episode 1/2 and pre-HL2. The Combine had to "burrow" their way to our dimension as explained in the HL2 dialog, and since it is also stated they come from another dimension/universe and used Xen as a stepping stone, this has already happened I think.

Of course, if you are talking about Portal portals, then again I say wait and let's have Episode 3 explain this one. My opinon is that the Borealis has some sort of wide-area Portal technology, hence why it disappeared from a dry dock - and why the Combine want it so badly. Whatever Portal technology is on the Borealis, it has the ability to potentially create intra-dimensional Portals at a very low energy cost, or at least would give the Combine the ability to figure out how to make them low energy. Remember the Core in Episode 1? They had to make that thing go supercritical just to open an unstable Portal.

Finally, I think everyone should watch this.
