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.

I have heard them say:

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

Honestly! Do you people actually watch all that nonsense produced by the nitwit network television stations or do they just claim you do?

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

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...

How do I get over a long-term relationship breakup?

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.

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.

What if Supergirl was a baby and not a teenager when she left Krypton? Who do you think will find her? What do you think things would be like?

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

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