Yes this does explain a way the hollow earth can exist.
Which is very important in considering a "world" view.
There are just too many stories from too many places that there are other people living on the other side.
And when there are so many stories all saying the same thing, there is some truth to be found there.

And here is another idea to blow you mind.
What if the world is flat? The 3D world we think about N-S, E-W, Up-Down is absolutely a rectangular box.
But this 3D world is folded into a toroid along higher dimension. 4,5 and 6

Like you get one of those flat balloons, and then you blow it up, and now it is curved, but it has also never stopped being flat.
