It appears too, to many people and I said it was a myth. I agree "They're getting smaller and then disappear" Just like a Sunset.
Not like any sunset I've ever seen. The sunsets in my world don't have the sun disappear into dot. Every sunset I've seen has the sun as a big orb sink as if setting behind a hill.
Like this:
I am a bit confused. You still talk about "sunken bits". Sunken means lower. Sunken into what? A flat plane does not have a lower point beyond where we can see.
That's the point of the investigation? Is it a flat plane or a convex surface? If it's flat, there's nothing to sink into. If it's convex, there is.
So, does it sink or not?
Are the sunken bits (objects) you speak of on the same horizontal plane?
Again, that's the question, isn't it? If it's flat, they are. If it's convex, they're not.
You know I'm stumping for convexity based on the appearance of bottom-up sinking. So my answer is "no." They are not on the same horizontal plane, and the bottom-up sinking is evidence of that.
Do you believe the Oceans are not horizontal in all directions?
No. Obviously, I don't. I conclude from the sinking phenomenon that the Oceans are not horizontal in all directions.
