That would be an effect of the properties of spherical space, but I think this is brought up in a bit so I'll see what I can say then.

Fair enough, just consider it a note for the future. That's the hardest part of, essentially, coordinate shifts between RET and FET. You can get it all to work mathematically but there are a lot of explanations that need to be different.

But it is flat. If I had an infinite ball it would be different, but this is an infinite flat plane that possesses all the properties of a sphere. The tessellations, spherical space, all of it could be condensed down into: "A flat plane that mathematically behaves identically to a sphere." I'm confused by how it would behave differently just because it is in spherical space. Could you elaborate?

It might mathematically behave identically to a sphere, but you still need to be able to demonstrate a way where that's possible. Certainly you can make it appear like a sphere from a distance, but for us to stay on its surface and for it to stay flat you need an infinite plane. From a distance, all the tessellations are overlaid. Take the following hypothetical:

You're on the infinite plane. You're pulled down, but not crushed because the plane is finite. You're pulled to the sides, but because the plane is infinite in each direction there's a balance between the forces.

Now, purely hypothetically, make it an infinite arc. Just by a couple of degrees, but now there's far more mass underneath you, off to either side. The infinite lengths on each side of you are now also that little bit below you. The downwards force from your sides is greater; horizontally still balanced, but there's more vertical.

Increase the arc, and the downwards force in turn increases.

Now imagine the curvature's complete, and all that infinite plane is rolled up into a ball. It still has the same mass, but now it's in a finite area. If you were standing there, the force would be a fair bit bigger.

That's the problem. You've used photos from space, but with an infinite plane in finite space all of that mass would be beneath the person. if you want to use tessellations as some way to excuse them, that works, but you'd need to explain how it is they don't have a similar effect on the Earth's surface and thus negate the infinite plane.

You can get a flat plane to behave like a sphere if you want, but that doesn't mean it'll behave like a sphere of equal mass to a round Earth.
