Are there any OTHER flat heavenly bodies out there?
If so, which ones, exactly?
If not, why not? Why is the earth unique in being flat?

If you drop an apple inside a vacuum chamber, will it fall towards the earth ?

Yes clearly, the medium cannot support it. Youre just changing variables and still not understanding that there is no force pulling downwards.

So, it isn't 'downward pressure' that makes a thing fall towards the earth then ? What is it that makes the apple fall downwards rather than staying at the position it was released at ? There is a force acting on the apple - it is either pulling it or pushing it towards the earth; what is the name of this force and where does it come from ?

The oceans aren't completely flat (or smoothly curved). They have dimples in them, caused by differing gravity (depends on the depth of the water / underwater features). Gravity isn't constant everywhere on Earth, and the difference can be measured.
Btw: How come GPS base-stations can give me pinpoint locations when I input:
a) a spherical coordinate system
b) a spherical model of the Earth
Also: what is this formula? Miles^2*8 / 12. Where did it come from, and what does it describe?
Curvature of what in feet, related to what?

You're free to believe anything you want, but I don't know how much more sense by all partaking of this thread can make to tell you that you are wrong.
The spinning wet tennis ball analogy is stupid. I'm not even going to go into the reasons why.

So instead of attempting to go in to reasons why the tennis ball analogy is stupid you choose to bring up a point I've already addressed and answered. The horizon doesn curve, I posted pictures from outside planes which is way more evidence than your own subjective opinion. And I told you why you believe you see a curve (the window isn't a perfect medium to see through & mental model believing you see a curve). Then I questioned why if you believe you saw a curved horizon, how come you dont also see 'down the side' to which I've received no answer.
I have an answer for all your questions because Ive asked them all before. I dont really feel like continuing to rehash the same answers over and over to people who don't seem to find any takeaways.
