# Thread: What would happen in this scenario?

1. I personally think the portal would pull itself inside out and collapse. Is that what would actually happen?

2.

3. The first portal ends up wherever the other portal leads it to?

4. I've seen this on the Futurama episode 'The Farnsworth Parabox'. They just become each other.

The episode with the two boxes? The one where Professor Farnsworth says, "The bible is the REAL good news"? "Now now, perfectly symmetrical violence never solved anything". Hehehe.

They don't become each other. They get pulled through each other simultaneously.

actually, that MIGHT be possible. They could envelope one another in a never ending paradox.

7. Lol, good question.

To take a shot in the dark, I think if such a thing could be done and it would interfere with other laws of the universe(like creating a harmful paradox) then both portals would collapse and be converted to energy(go boom!). Cause if the states of the portals can be expressed mathematically and the scenario of both portals inside each other cant be expressed mathematically then its not physically possible and something else has to happen to prevent this impossibility from materializing :?

8. Topologically... the table you push through the portal will start coming out of itself and "hit the side of" the portal it's going into, whatever that means. Presumably this implies you can't push it all the way through, at least at the depicted angle.

9. Depends. Assuming the other table is small enough, it could clear the portal anyway.

10. I'm going with the picture, which has specific dimensions and suggests a particular angle that the one table is going into the other. Assuming that the "portal" means those two ellipses are glued together in an obvious way, then what I said stands.

11. The blue portal would disappear forever because it would make infinite copies inside the yellow portal. Therefore the yellow portal is now a 1 way hole to nothingness.

But that depends on how long it takes for the transportation.

12. it impossible because portals don't exist. If they were connected by wormholes....well that would be a different story.

13. Someone's been playing Portal. (Awesome game. Love it.)

Avoiding anything witty about what would happen in-game...if you take the concept, I would guess that the matter would probably be torn apart, or would explode.

Particles entering the blue portal will come out of the orange portal, but at the point of entry the particles are also coming back out. If the alignment is identical, you'd have an instance where an object was trying to occupy the same place as itself. That leads to a few questions:

1. If the exit portal is rendering a copy, then the exiting particles would be identical, but you'd have two particles trying to exist at the same point. This will likely cause some problems, although time may play into the issue...

2. If the exit portal does NOT render a copy and simply transports the particle across, then the particle is trying to occupy the same point in space, but at different times, assuming that there is a time difference between entry and exit. I'm not sure what would happen there, but it might be as odd as watching an object unfold itself in the opposite direction, or you may simply bang into the object and never be able to push it through the portal.

As for the slabs themselves, with the portals, hard to say. Since each portal has a frame of reference before and within, and each contains each other, you're likely to simply do nothing. Although you're also likely to cause a cascading containment effect that might spawn a mini black-hole.

It would be cool to see what the game engine does, but I don't think the editor, or the game, will allow you to fire a portal onto a moving brush object. (Probably a sneaky way in which the developers looped around portal collision issues! )
