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

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

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

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.

Do you believe that the portrayal of smoking in films and music videos contributes to the glamorization of cigarettes in society?

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.

How do I get fit at home?

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.

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

…and there are probably other ideas out there.

Why do the Republican city officials at Springfield Ohio continue to deny that immigrants are eating pets to sabotage the Trump campaign, even though immigrant pet-eating is now widely believed to be true?

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

I have heard them say:
