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

I have heard them say:

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.

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

Why do people turn a blind eye to bad behaviour if someone is very good looking? Whereas if someone is ugly, they get harshly judged for everything?

…and there are probably other ideas out there.

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.

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

How will the 2026 delimitation affect India as a whole keeping the new count of 888 seats in mind (not the current 543)? I’m looking for genuine answers with facts and not rhetoric. I will only listen to answers and not reply to any of them.

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

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.

Can you share any "backstage pass" experiences you have had at concerts?

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

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