Flat earth confirmed

That is usually one of the main proofs that earth is flat. The pilot doesn't have to keep lowering the plane in order not to fly higher, the fly completely level, yet the plane flies in a curve around the earth.

Flat earthers have no sense of scale.

you jest but the model to be used is the simplest model that works in practice (to make useful predictions). Since most use-cases are machine building and construction, the curvature of the earth rarely matters. as such, "the earth is flat" is often the best model for a task. a spherical earth only really matters if you're dealing with either world-wide trade, geopolitics, or astronomy.

....but it has to go like nuts to stop falling out of the sky ?

This is just silly. It just means the earth is flat there. You need to repeat this everywhere on the earth and then we'll know the whole earth is flat. Or at least do it in a few different places hundreds of miles apart.
Well if you averaged out the distance from the centre of the Earth over the whole world - it would be absolutely flat....

Do you know, I think it might. If the ball is weighted on the bottom, it will still sit at a slight angle, if the surface it sits on is at an angle. And being spherical, it can then detect slopes in any direction.

I think one would still believe in gravity, just not the same way as normal people. It would have to be a constant field "downward" rather than masses attracting.
Planes can obviously go fast enough to counteract gravity...

How do you tell how big it is? There's no size reference at all.

It can show you if there is a slope, maybe. If it is properly weighted then it wouldn't even do that.

If it's properly weighted, I think it will show you the slope. Imagine a circle on a sloped line, weighed at the bottom. If the circle is upright, so the weight is at the bottom, the point of contact is a bit above the bottom of the circle.
The direct distance from the point of contact to the bottom of the circle has to be less than along the perimeter; also the angle to the circle's bottom has to be shallower than that of the slope.
Therefore, if the circle rolls down until the weight (that used to be the bottom) is now the point of contact, the point of contact travels a distance along the slope equal to that arc (perimeter) of the circle. The new point of contact must therefore now be lower than the bottom of the circle was before.
So the circle will come to rest with the weight at the point of contact (or above?), i.e. the circle is now tilted. Similarly, the ball with a weight near the bottom will sit tilted on a sloped surface.

You take that back, earth chan is not flat!
(For those who don't get it, it was a funny meme like 10 years ago)
