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

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

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.

…and there are probably other ideas out there.

Why do siblings (or other close relatives) stop visiting each other as they grow older? Why does this happen with so many people nowadays?

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

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.

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

How do you feel about the impending end of what Donald Trump calls "the Green New scam"?

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

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

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

I have heard them say:

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