The Void at the end of the Landscape #47

Some say that the earth is flat, as if there was an end to the journey, as if it was possible to fall into a void at the end of the landscape, to fall infinitely to the end of the vase, beyond the edges of the universe, this is difficult to happen, but how to know if there's a bottom of a hole if we don't jump? even if we jump will we have left or will we arrive at the same place?
