Sounds like you are supporting FE Theory, of which the edge is a significant part.
No. I think Socrates, Plato, Aristotle, and the others like them all had it right. The Earth is a sphere and space is 3-D.
In the spherical Earth, everywhere is another edge and just around the corner of it, since there are as many tangents to the sphere and corners around and around as there are points on the surface.
You should consider the equator and the great meridians. Each longitude around the Earth is part of a great circle around the Earth that intersects the equatorial plane at 90", and they all go through the North and South Poles. Also all the 24 hours of the day are
around the Earth at once. It's always high noon and midnight around the Earth somewhere, with all 24 hours in appropriate sequence roundabout it, which shows that it is a sphere.
Do you reckon that the Moon is a sphere but the Earth is not?
