Well yeah have it at an angle. I still feel as if the beam would keep going until an object got in the way. I kinda based this on SuperPosition. I don't know a lot about physics so, I guess my first reasoning of the situation was the correct one.

portal inside portal solution!

so you will feel opposite force and you can't do that!

WTF? A portal shooting out through itself? Oh my aching head...

As for the whole "portal-into-a-portal" thing... If you enable sv_cheats and sv_portal_placement_never_fail, then shoot two portals at the EXACT SAME SPOT on a surface, it looks like one portal that has a mirrorlike surface. You can walk right through it, and you even have Ghost Collision (to use a ProjectFUN term) with yourself. If it was possible for a solid object to have Ghost Collision with itself in the real world, then you can have a mirrored portal event like this. It also makes it seem like one Companion Cube has become two
Seeing Chell and the Portal-Clone Chell inside each other is best seen if thirdperson is enabled.

Laser going infinitely through a portal: I saw a YouTube video about the Portal Playground map (which I can't seem to get it to work... Could someone tell me where to find a .bmz version of the map plx?), where the player had two portals on opposite walls, directly in front of the Rocket Turret, and if it was at exactly the right location, you see multiple targeting lasers shooting across the room. Then the Rocket Turret fires, the rocket goes through the same portals multiple times, and it eventually hits itself with its own missile XD

It is possible to slice yourself in half with a portal. Usually, the game teleports you out of whichever portal end you're less into, but if your midpoint is at the exact level of the event horizon (where you're officially "inside" the portal), and you shoot one portal somewhere else, you get killed. This has only happened once, and to do it, you have to do it at the part of the facility where you stick your head through a portal to get on top of a crusher. I wonder what would happen if you spawned a Storage Cube in the portal, then fired another portal elsewhere? Would the cube do like what happens with a fizzler?

As part of a previously mentioned required test protocal, we can no longer lie to you. We have broken the laws of physics. Again.

When you shoot a portal at an object, such as a cube or a camera, it doesn't hit the object. It goes through it onto the surface behind or underneath it, causing the camera to crash and burn, and the cube to fall into the incinerator.

no that was if you shoot portal on wall another portal on wall and grab wall (with portal) and insert it into one portal...

Okay...

Well, since the game removes any portals on an object that starts moving (like the platforms in the Portal TFV mappack), the only way to make the object move the portals into each other without destroying the moving portal is to stretch space like a rubber band. Local space-time around both portals would be normal (or at least what IS normal space-time for a portal ), while the physical distance between the portals would decrease.
Of course, warping space-time like this within close proximity to a portal might asplode the universe, like trying to open two wormholes near each other, or opening a wormhole from within a black hole.
Okay, none of that made any sense whatsoever. Maybe I should try reading some of Stephen Hawking's books before trying to explain this type of thing again... Anyone know where I can get a copy of "More Things You'll Never Understand"?

Isn't it great how everyone reads the first post before commenting?

Do you have any idea how old or long this thread is? I haven't even read all of it.

blasphemy.
yeah but who the fuck has THAT kind of time.
but i think what he meant is the FIRST post, in that they say if portals could be used in the real world. NOT following the "hl2.exe" version rules

Yeah i meant just the first post, which kicks off the discussion.
It helps to know what the thread is supposed to be about instead of reading the last post which could be horribly off topic.

rellikpd hit the nail on the head.

probly wasn't read

I've got some very important scientific questions about portals.

Such as, if Shroedinger's cat had possessed a portal gun, could it have escaped from the box?

Or, what if the portal was not in the shape of an oval, but rather the Mandelbrot set?

Okay, those were jokes but I've got one serious one.

If you have a portal in one area that is pitch black, and another portal in one area that has light, would the portal illuminate the dark area? I guess so, because light must travel though portals because otherwise you couldn't see out of them. I suppose it would look something similar the light inside of a building traveling through a window to partially light up the outside at night.

Yeah, and turret lasers go through portals just fine. And if you do the infinite-mirror portal, you can have a rocket turret do a very long laser beam.
And about reading a whole topic before commenting, I think that reading the first page and the last two or three pages in a 4+ page topic is sufficient. For a relatively new topic of three or fewer pages, it's a good idea to read it all.

I can't fully recall when I was last on these boards, but I'm seriously impressed that this thread is still on top of the forum...

It would be the same if you had a dark hallway and opened a door to a room with the lights on. Light would spill out of the room an partially light the darkened hallway. I would assume light would behave the same way through a portal since a portal is in essence, a doorway.

However, since the Source engine sucks with dynamic lights, it is not featured in Portal. That's why all test chambers are equally bright lit, I think, and there's also no shortage on light in the BTS areas, even though GLaDOS does not need the light there. I mean, she hasn't got cameras there anyway, now does she?

True, but the bts were originally for the crew that used to work there before GLaDOS was installed. They needed the light. GLaDOS doesn't need stairs and catwalks either, but they are there too.

Yeh, but she can't do much about them, and why should she? They're just... standing there, falling appart.

However, the light requires electricity. Why have those lights on if you don't need them? You could save the power. (I presume the facility runs on some kind of private reactor, especially if Portal takes place after the Seven Hour War GLaDOS would have a hard time obtaining electricity)

Dude portals! you could have a nuclear power station below AS and have it linked with the sun.

this is a great idea. I think it would be good to have lights off in bts areas; only the orange ones should be there bright enough just to give the player a clue how to turn the lights on (a light switch probably)
