This is a fun read on wikipeida [1]. I'm curious as to how you could disprove it at all: there's a perfectly valid coordinate transformation that maps our "infinity" to the center of the earth, and the center of the earth to infinity. All the laws of physics become position-dependent, of course, and it's not a convenient space for calculations, but it "proves" that the concave earth is a perfectly valid way of describing the universe.

I don't understand the difference the entry makes between the fact that you can represent the universe in a CHE model using coordinate transformations and "hypotheses". Given that you started from a concave model of the universe and the associated physical laws, you could make reasonable hypotheses and verify them through experimentation.
