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

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

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

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.

If Russia needs the resources to fund the war in Ukraine, why doesn’t it throw open its doors to visa free western tourism? Enough people would be interested, & it would start to get some hard currency as €, CHF, £, SEK, $, JPY in the tills at shops.

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

I have heard them say:

…and there are probably other ideas out there.

Is there a type of function where every point has exactly one tangent line passing through it? If yes, what is this type of function called?

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

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

Are there any more 'nun' jokes?

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

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