That’s what I like about it. You have point. But this point projects from itself at a 2D angle. But as this point is a sphere that’s projecting, the angle is now a cone.
This could go on forever but no.
That point is within a sphere.
So what happens to the projection at the boundary of the outer sphere? Will its curvature continue outwards beyond its original home?
Nope. Not if you flatten the sphere at the exit zone.
From that onwards, it follows 1:4:9:25 etc and can be treated as a nice flat thing.
I like that. Might be inaccurate but it’s how I envision it.
