Rules
This is a science community. We use the Dawkins definition of meme.
I think you'd be able to get it in a little ways before top of the box pushes against its own lid, preventing it from going in any further. If the lid pops back open, then the top of the box will begin sticking out of the box which will likely make it too wide to fit all the way through the wall portal.
But the rules of Portal is that the portals themselves break when moved by any substantial extent anyways so in the game it would just disable the portal altogether.

It's the scene with the lasers innit? So many "paradoxes" are solved with the answer of "portals cannot move relative to one another," and then they do the bit with the laser. -_-
The thing is, movement is relative. Everything on earth is constantly in motion if you're observing from any other celestial body, so motion itself can't be what breaks portals. What it might be, though, is acceleration. Those panels in the video seem to be moving at a constant speed, so aren't experiencing any substantial acceleration, making a portal on them possible
you can say they cant move 'relative to each other', but what about the universe supposedly expanding?
The same reason the Earth or your body isn't expanding along with the universe - gravity is stronger than the expansion rate
They can move at a constant speed in a constant direction, but the acceleration would break them.
Heres an answer from minutephysics
I guess the question becomes if one portal is in a box, what happens to the box? Does the whole process just get blocked after the first few inches as the outside of the box collides with the inside; does it push itself open; do the portals just slice though and turn the pieces of box in the way into confetti?
Just came here to check whether someone already posted the minutephysics video.
I think their explanation is rather good for passing portals through themselves. The box doesn't add much to the equation: it is just physical objects smashed into eachother...
Can't move portals.
Of course you can. They're on moon rock. There are a few puzzles with moving platforms with portals.
You can't place a portal on anything the game physics would allow to go through another portal.
Yeah but that's by game design, not internal world logic.
Theoretically you can if they're moving in a constant direction at a constant speed a la an inertial frame.
That doesn't work because gravity makes the game's reference frame non-inertial. One of the big takeaways of general relativity is that idea a reference frame that's inertial except for gravity is meaningless. Even ignoring relativity, everything is subjected to centripetal acceleration due to the Earth's rotation (and the story canonically takes place on Earth).
I think the real answer is probably the least satisfying: the game's physics just don't correspond to real physics. Most portals appear to exist in a privileged reference frame that can be said to be motionless, but even that isn't the real rule; the real rule is that portals can exist where the level designers want to allow them to exist. They try to make it feel like there's a certain logic behind it, but they'll bend the rules as necessary to make a cool puzzle work, and they keep the everything consistent within a single puzzle, but some subtleties of how portals appear to work are subject to change between puzzles.
As far as I'm aware gravity doesn't directly act on portals so I don't think they would experience acceleration from Gravity themselves. Though I was thinking about it more in terms of general relativity rather than Newtonian gravity.
Except that one time in Portal 2.
When you cut the tubes to the big gas chambery thing.
So how do you find a box that can fit a blue portal inside, but also itself fits through the orange portal; given that both portals are equal in size?
Turn it
Duh, that makes sense
Pivot
Is their anything that can escape the "self referential" paradox?
Gödel and Russell would be very pleased. Or maybe dismayed. I'm not sure how they felt about their discoveries.
It would repel or bounce the box as each portal acts as opposite like magnets.
it just turns the cosmos inside out like a sock . Don't do it.
I just assume as soon as one touches the other they fizzle out. I guess the top of the box gets cut a bit.
It's like folding space. They basically occupy the same location. Its just two "sides" of a 2D plane. The portal can't go into itself.
Worst case if it can it's like bottle so they just flip positions and the whole thing reverses and the box just comes right out and the colors swap.
Nothing crazy.
It will hit the lid
you open a rift to the astral plane.
Portals can only move within planes parallel to each other.
The result is a box with a portal in it, in a box with an portal in it, in a box with an portal in it, in a box with an portal in it........∞
Explosion :P
Portals cannot be moved. Try putting a portal on a moving surface in the game, it disappears.
Should have used circles, like a manhole cover
You cant move surfaces with Portals on them
