What do flat Earthers think causes the "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.

I have heard them say:

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

Which bands became massively popular for covering songs rather than recording originals?

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.

…and there are probably other ideas out there.

Why are there no fossils for the 'missing link' that connects our ancestors with other species? Is this a misconception or is there another explanation?

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”.

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

Why do people keep denying the similarities between Latin and Italian by saying they are totally different languages when it’s obvious they sound similar?

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

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