Oh, alright,

You just essentially rephrased what I said...

kind of. you said nerve endings, which is technically incorrect. I was just clarifying that it presses on the axon or dendrite of the nerve, but not the ending itself unless the break actually punctures the skin. Again, I am just clarifying so as to educate everyone and prevent further misuse of, "nerve ending."

Oh, alright,

From what I can tell the three top pains are in order
Femur breaking
kidney stone
childbirth.
But I dont have a confirmed source its really scattered.

that's an error in coding, not logic.

given the second game specifically calls for placing portals on moving objects (best seen in the deadly neurotoxin room, where you have to shoot portals at moving platforms and another at a laser to cut the wires)

Please explain to me how you cannot place portals on moving surfaces.

EVERYTHING is in constant motion. The earth spins around it's own axis as well as travelling through the solar system at enormous speeds at any given time.

The moving surface rule is clearly stated in the first game. No reasoning was given, However in the second game when cutting the pipes for the neuro-toxin you place portal on moving platforms.

1: gravity pulls it downward, may also tilt and start making strange zig-zag copies depending on how the portals were placed. Remember when the room would 180 As you entered a portal?

2: Bar would apply pressure in on itself, tilting, bowng, and eventually breaking, possibly might moving the portal surface when it comes into contact with the portal edges.

3: My original Hypothesis would be that the pipe is cut in half where the portals meet. However in game experience shows that placing a new portal with an object inside of the portal merely displaces the object from the portal field fully intact. presumably the pole would launch out of the blue portal in it's original state with a couple extra pieces of soder on both ends. I believe the sodering would break when the illusion of a inifinite pole ended.

in the second game you place portals on moving objects, nowhere in the first game does it state portals cannot be placed on moving objects.

true, it doesn't "say" in the first game that you can't, but if you try to place a portal on a moving object it fizzles out as if you were shooting a non-portalable wall.

that's an error in coding, not logic.
