What do flat Earthers think causes the "magical downward force"?

The trouble with (1), (2) and (3) is that these cannot explain why the force of gravity varies with height above sea level…less at the tops of mountains - more in valleys.

3. Gravity doesn’t exist - it’s a form of magnetism that works on non-metals.

I have heard them say:

Do flat Earthers really exist? Why do they believe the Earth is flat?

They don’t know - and not all of them agree that there is a “magical downward force”.

1. Gravity is real - but the Earth’s disk is very thick so the force is very nearly vertical.

4. Gravity doesn’t exist - things are held down by air pressure.

What are your political and economic beliefs? How did you form them, especially in comparison to those who hold opposing views?

…and there are probably other ideas out there.

2. Gravity does not exist - the Earth is accelerating upwards at 9.8 m/s2 which seems like gravity.

If (3) was the case - you’d have the same problems as (1) - but this weir...

Has a conversation with someone who holds opposing political views ever caused you to change your own beliefs?

If (2) was the case - then the acceleration would have to be EXACTLY the same everywhere - and it’s not.

If (1) was the case - the center of gravity of the Earth would have to be so deep down to avoid gravity pointing off at an angle when moving towards the “rim” of the flat earth that the difference in height of a mountain would be negligible and we would get very, very nearly the same gravity everywhere.
