Passing A Portal Through Itself

This video is about what happens if you try to pass a portal (like in the video game Portal or Portal 2) through itself - do you get a paradox? Infinite recursion? Impossibility? Contradiction? The end of the world? Collapse of the wavefunction? Ultimately it ends up looking beautiful and weird and recursive and... just watch the video :)

I love how it's just generally accepted now that Portal's Portals are the only things we're allowed to use for diagrams with portals.
-
I can see why the game designers avoided dealing with this through the simple expedient of making the portal close if it's moved.
-
It’s shocking how well you explained such a trippy and abstract idea in such a short amount of time

Portals actually are everywhere, the problem is they're all back to back, with no way to separate them
-
Portal physics must be the thing that keeps this guy up at night and he had to explain it or he would die from curiosity
-
This is a troubling thought that I had as a child ever since the release of Portal 2. Thank you so much for solving this 😊

I'd love for you to make a similar video about a more general problem with so-called scaling portals, i.e. those that vary in size, and when something falls into one portal, it comes out of the other with a proportionally changed size. For example - the blue portal is 7 times bigger than the orange one, which means that if a 1.75 meter tall man entered the orange portal, a 12.25 meter tall giant would come out of the blue one. However, if the same 1.75 meter tall man entered the blue portal, a 0.25 meter tall dwarf would emerge from the orange portal. My question is - what would happen if you threw a smaller portal into a larger one, and would it be possible to throw a larger portal into a smaller one if they had the right shapes, and if so, what would be the effect. You will make me very happy if you make a film about it.

I like the fact that if you're thinking with portals, they always will be blue and orange. It's hard to imagine using other colors for em.

Someone's been replaying Portal a lot haven't they?

welcome to “I don’t understand anything but this is cool”
-
Glad to see Portal and Portal 2 are still iconic enough to be the way portals are drawn in 2022
-
I like how he just talks about Portals like the ones from the game are the universal standard when we talk about Portals.
-
I love that you used the Companion Cube! The Portal references are amazing!
-
An important detail here is that each portal must have a backing that blocks entry such that entry is possible only through the coloured fronts of the portals. Changing that changes so much.
-
I'm convinced Henry is making real, working Portals and is posting videos of him testing new features for people to point out so he can fix it. Very effective debugging process.
-
i love how portal has completely changed how we interpret portals and we always see it as one orange and one blue one
-
This is one of the greatest videos I've ever watched.
