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.

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

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

I have heard them say:

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

What would you do if you were lost at sea in the Florida Keys?

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

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

Democrat voters, why are you so naive, easy to manipulate, can't see a liar standing right in front of you and why won't you research your party? You will find they have a plan for all W. Nations and it's evil.

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.

…and there are probably other ideas out there.
