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.

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

…and there are probably other ideas out there.

What is the meaning behind people claiming to hear voices of God in their heads without anyone else hearing them? Is this a sign of mental illness or possession by an evil spirit?

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

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.

Why do almost all vertebrates have tails, but not apes and frogs?

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

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

I have heard them say:

First look: The new Pedro Pascal-narrated space show in NYC - Time Out

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

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