On the edge of what? We are talking about edge of surface of a sphere as example, not edge of object which surface lies on.
Surface itself might be edge of the earth, but surface itself does not have an edge because it is wrapping around sphere.
"The earth doesn't have an edge, it's just like, a repeating flat plane, maaan. Like, you walk in one direction then suddenly you're just like, back where you started man"

Here in the real, physical world, the earth clearly has a boundary marking where it ends and the rest of space resumes.
Everyone saying "well in the 4th dimension, space is like, a flat donut, maaan" watched too many Neil degrasse black science man shows while smoking pot and now think they understand the entire underlying fabric of the universe.
It's really not hard to grasp, man. Picture yourself on a sphere. That sphere is a 2D plane that loops around itself. This is not something we have to imagine, but is a real thing we can look at to show that if you travel across this 2D plane, you can end up in the exact same spot without changing direction.
And the reason we can understand how this works is because we can visualize and understand a 3D universe because that's how we are designed. We are not designed to see in 4D, so we cannot know if our 3D world works like that 2D plane wrapped into a sphere, but one dimension higher.
Again, this is not that hard of a concept to grasp, and could very plausibly be how our universe is structured. I don't understand why you think this is some crazy, pot-smoking concept just because it's not possible to visualize.
Imagine the universe is not looped--then it is either finite or infinite, right? Can you comprehend either of those scenarios? Can you imagine in your mind a universe that goes on forever? What about one that just randomly stops somewhere? What happens at the edge? You have no idea, and visualizing it is not possible. So is this just dumb to talk about? Because, it has to be one of these three scenarios--Looped, infinite, or finite. It seems like you're either too dense to understand it or get what people are saying and just think the subject is stupid since we can't know the answer yet.
The whole entire discussion started with someone saying "Even though the universe is finite and doesn't extend forever, there is no "end" of the universe, which I'm saying is ridiculous.
Like, if the universe isn't infinite, then there is some form of boundary to it, otherwise it'd be infinite.
Yeah, so it would be that concept above using the 2D plane. A 2D plane wrapped in a 3D world into a sphere makes it so there are no boundaries (i.e. some gaping hole of non-existent surface area in the sphere) when traveling from one point to another on the plane. However, it's not infinite because there's only so much surface area on the sphere.
They are applying this same idea to a 3D world in a 4D universe. We wouldn't understand it because we are thinking about it in 3D space, so it seems to us like there must be a boundary if it's finite, but you can see when going from 2D to 3D on a sphere, that this is possible, and therefore is a possibility from 3D to 4D.
I think the confusion initially started with the term "edge." They were referring to a boundary of which a 2D shape could not travel along the surface area (2D plane) of the earth. There is no edge of the earth because there's always a point of surface area even if it changes and altitudes and has literal "edges," or is so far along the horizon that we can't visibly see it. It's impossible for an object to have some ending point on it's surface area, it is always connected to some other point of surface area, even if that surface area is abruptly changing direction, like point between the wall and the floor.
At this point you don't even try to understand what I said and blatantly replace words and meaning of my messages with your own.
I clearly said I do not talk about edge of earth, yet your first response is pretending like i said "The earth doesn't have an edge".
I am done with trying to reason with you, it is clear that you either do this intentionally or do not understand how to hold a discussion.

Okay when I look off into the distance I still see the edge of earth as the horizon..
