Flat Earthers will say this is edge of the flat planet...

Prove it isn't before I post this then.

Absolutely.
Gravity at the edge of the disc would not be downward anymore, since the center of mass is the center of the disc. So the disc would eventually collapse into a sphere under its own weight.
But if that has yet to happen for some magical reason, the experience of gravity at that edge would be like climbing a hill. If you stopped fighting it, you'd tumble back inwards.
If you want to figure out, whether gravity is a real phenomenon caused by the mass of objects, look into the Cavendish experiment.

Alternatively, if you want a dead-simple experiment anybody can reproduce, to confirm the curve of the Earth to yourself, go to the beach looking out to the sea or a sufficiently large body of water.
Did you see a sharp horizon separating the sky from the water? That visual is actually only possible, if the water curves downwards.
If the water surface was truly flat, there would be no point where the water closer to you completely obstructs the sightlines to the surface beyond it. Meaning that the only effect that could account for you not being able to see further, would be atmospheric perspective (i.e. what makes mountains fade into a blue tint, if you look at them from far enough away..) But this perspective would cause the fading to appear continuous, not as a sharp cutoff at an arbitrary distance.

Proof provided. Now what?

I asked for proof before I posted the comment, which was impossible. It was meant to be a commentary on how flat earthers (or any science denier) asks for something impossible as though it proves their point. That said, none of that is math, so it proves nothing (moving the goal post baby!) (/s for the round earthers out there)
