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?

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.

[-] caseyweederman@lemmy.ca 9 points 2 years ago

Yeah but that's by game design, not internal world logic.

[-] Laticauda@lemmy.ca 6 points 2 years ago* (last edited 2 years ago)

Theoretically you can if they're moving in a constant direction at a constant speed a la an inertial frame.

[-] lolcatnip@reddthat.com 4 points 2 years ago

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.

Except that one time in Portal 2.

When you cut the tubes to the big gas chambery thing.

Box moves 1 inch and the portal poofs due to an unstable surface.

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?

Duh, that makes sense

Move it really fast and let relativity do the rest

Is their anything that can escape the "self referential" paradox?

[-] lolcatnip@reddthat.com 5 points 2 years ago

Gödel and Russell would be very pleased. Or maybe dismayed. I'm not sure how they felt about their discoveries.

[-] nyakojiru@lemmy.dbzer0.com 11 points 2 years ago

It would repel or bounce the box as each portal acts as opposite like magnets.

[-] veganpizza69@lemmy.world 9 points 2 years ago* (last edited 2 years ago)

it just turns the cosmos inside out like a sock . Don't do it.

[-] oxideseven@lemmy.ca 8 points 2 years ago

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

Oh, okay. It has a scene where you have a portal go into a portal.

[-] ASeriesOfPoorChoices@lemmy.world 4 points 2 years ago

you open a rift to the astral plane.

[-] JakenVeina@lemmy.world 4 points 2 years ago

Portals can only move within planes parallel to each other.

[-] Zerush@lemmy.ml 3 points 2 years ago

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........∞

[-] mvirts@lemmy.world 3 points 2 years ago

Should have used circles, like a manhole cover

[-] PlantDna@mander.xyz 3 points 2 years ago

Both portals should the same size. Fitting one in a box, means the box should be too big to fit in the other portal.

[-] vithigar@lemmy.ca 13 points 2 years ago

They're ellipses. You put one on its side and it fits through.

[-] pfannkuchen_gesicht@lemmy.one 7 points 2 years ago

If portals were circular, that would be true, but they're oval.

It isn't shown explicitly, but notice in the last panel with the box, the box is much wider and much shorter. It was rotated 90°.

THIS is what happens when you succeed in making an AI ( or Hoomin ) that can create MODERN KOANS.

You Bastard!!
