not sure what you mean by gravity but the earth doesn't look concave, it looks flat, period.
Hi @FlatEarthOrg, have you considered the possibility of a concave earth, where we live on the interior surface of a spinning sphere, the antipodes far above our heads? This could also explain gravity as a centrifugal force, and our ability to circumnavigate via the South Pole.

Though the Flat Earth FAQ says it would look flat regardless, because we can't get high enough to view the curvature, and that ought to apply equally whether it's convex or concave...

I wouldn't borrow such an original idea! ;) By the way, how are you doing "up" there?

I hate to spoil it for you but a concave Earth would still have its center of mass in its center. And the apparent centrifugal force would be unnoticeable unless it's spinning very fast. In which case the Coriolis effect would be so great that you'd witness it even while walking

I know you're pulling our leg, but I couldn't resist some pedantry

It seemed sort of an obvious possibility, once you've decide only to look at local curvature... ;)

Obviously that can‘t be, because everybody knows that spheres are dark inside.

The earth evidently has the shape of a Möbius strip. That should be obvious.
