Heres a scenario ive been thinking about?

what if you took 2 portals, and made them facing the same direction, in the same location(not passing thru eachother, just in the same location) facing upwards and then dropped something into it from 10 ft up.
what would happen? and what would happen if said object was you?

I've tried it ingame. Just put 2 portals next to each other on the ground, and drop an object in. They just fly up and down in the portals. The object can't collide with itself because there's only 1 object. Another copy of the object isn't magically brought into existance.

Anyways, try it on an unsuspecting turret. It's funny as hell.

Turret goes WAAAAHH!!

he didn't say side-by-side. he said LITERALLY occupieing the same space. this could only be done with hammer or something. since the game makes them bump away from each other.....

Depends on the portal technology. In Valve's Portal, stuff cannot collide with itself, so it just bounces back out (same thing as if the portals were not in the same spot). In Portalized, stuff can collide with itself, so you can't push something through a mirror portal unless it's small enough to fit in one side and come out the other side. Think about it - portal mirrors are not real mirrors where right is right and left is left - going into the right means you come out of the right of the other portal, which, if it is turned backwards, means you come out of the left.

Something i noticed in regards to flinging yourself upwards in the last room in Testchamber 18. You place a portal on a platform, then jump through a portal on the bottom of a pit to fling yourself upwards. However, you enter the 1st portal feet first, so, according to common sense, you should come out the other end feet first, upside down. However, you come out headfirst, which shouldn't be physically possible.

Anyone care to elaborate on this, or are we gonna assume that Valve decided to screw the laws of physics a bit more to make vertical flinging easier.

I just seen Chell curling into a ball and uncurling in the other orientation. Divers do it all the time. It would be incredibly nauseating and disorienting and difficult to render, so they just skipped it. But I don't see it being physically impossible by any stretch.

Good point there. Case closed. NEXT!

Anyways, lets get back on topic, anyone else got a question?

well, lets think of this:
in portal, you can stand between 2 portals, placed on a wall.
the problem with that is, the gap between the portals is about 0.000001 mm thick, therefore wouldnt you be sliced in half?

You'd probably run into yourself, resulting in you not passing through the wormhole between the portals as you cannot enter the portals. You're blocking yourself at the exact point where one portals morphs into the other. You can only enter one portal at a time, as well, but since portals can only be entered from 1 side (try it with noclip, you can't enter a portal from the backside), you would exit the other portal, and run into yourself.

I thought we already solved this one earlier?

@Coop: I don't even understand the problem as stated, but you're probably right. Someone should write up a tl;dr version of this thread on the wiki with answers to some of the simpler questions.

I have this new speculation that I just thought of.

We all know how if you were to spawn a portal above you and then one directly below you, you would fall endlessly till you decided to stop.

Well what if you were to simply turn on a laser and have its light facing down the portal, logically the light would go through the bottom portal and out the portal above it and so on and so fourth just like you were when you were falling.

Now remove the laser, what happens to the previous beams? They must still be there right or no? I mean would the beam of light continue going through from the previous beams you shined or what?

What I'm trying to say is, shouldn't the beam continue endlessly like you even without the laser feeding the beam?

At first I was like if you remove the source then it will just disappear, but thinking heavily on it. If the beam were strong enough, it should keep on going till it hit something to stop it.

If I'm not explaining it well enough just ask questions.

Well, first off, the beam would not continue forever with the source on because the source of the beam would be blocking its path.
For instance, if the source was a laser pointer, the laser beam would enter one portal, exit the other, and stop on the back of the pointer.
Secondly, considering the speed of light and the physics of the portals, I believe the beam of light would simply end once the source would turn off.

If you could have a beam without the source, then maybe you might get some interesting infinite multiplication effect with the beam when its on, because the beam would follow the same path, become two beams, then four, then eight, etc, ad infinitum.
