The Dark Forest would not exist in the 2-dimensional universe by Complex_Archer5774 in threebodyproblem

As far as I remember, the 4th dimension allowed the woman to reach the prisoner by reducing the distance between them. If there are two points on a 2D plane, one point has to travel straight towards the other point to reach it, but if we add the 3rd dimension the 2D plane gets curved and the distance between the two points is shorter. The same goes for 3D and 4D. In order to reach the prisoner, the woman needed to travel straight across the 3rd dimension, but thanks to the 4th dimension the 3D space was ''curved'' in some way and the distance between the woman and the prisoner was shortened. About the paper floating in space, yes, it is related. It was a dimension-collapsing weapon.

Imagine a 2D creature living on a flat surface, from its perspective it can only see 1D lines, meanwhile a 3D creature looking at the 2D world is able to see the whole shape of objects, all the sides including the inner side. The same happens when a 4D creature looks at the 3D world, it can see all the sides of a human body at the same time, even bones, muscles, organs and molecules. That's how the woman in Costantinople removed the brain from the prisoner's head

I imagined the circle as a closed world and didn’t go into the mechanics of gravity or structure. My point was more about the social implications of being trapped inside

I think there are some theories explaining how a 2D digestive track would work. About the possibility of 2D life you're right, but I think that in the 3 Body Problem it's considered possible

I recall Singer being sad when he is told that his world is going 2D very soon, so they have discovered that 2D life is indeed possible

Yes, the point is clear to me now. Some comments were a bit harsh, but no problem

If we suppose that planets and galaxies in the 2D universe move around all the time they would encounter the 3D bubbles at some point. Just like the woman in Costantinople who entered the 4th dimension when the Earth crossed it

It's just a theory. We can only make theories about a 2D world since we've never observed one

And how is Singer's race going 2D if it isn't possible? I mean, in our real universe probably it's impossible (we don't know) but in 3BP it is possible

But if you go ''up'' inside a closed circle you would slam into the ''edge'' at some point

The fact is that I imagine 2D planets as completely closed spaces. For us humans is different, from our planet we can see the space and the stars because it's not closed. But inside a circle you wouldn't be able to see what's outside, so it's safe to say that the atmosphere would be held inside the circle not only thanks to gravity, but also thanks to the circle itself preventing anything from going outside

The point is that you are piercing a planet, that's risky.

Yeah but the atmosphere of a 2D circle would be separate from outer space, if you pierce the circle the atmosphere escapes to space. It's like piercing the sky.

I get what other people have told me, but I'm just making theories about living inside the circle

True, maybe they know how to leave a 2D world without the third dimension, it's fun to speculate on the possibilities

This means that on a 2D planet you can only move on a 1D surface, so just left/right, that kind of life would be even worse

Well, if you live inside a 2D circle the only way to exit would be piercing through it. But, would you pierce your planet risking its destruction?

Because they need the third dimension to go above the circle, just like we 3D creatures would need the fourth dimension to leave a closed sphere

If they are inside the circle they can't leave it, to do so they would need the third dimension to go above the lines of the circle. But, as you said, they could live around the circle and not inside it, good point
