If I were rich, I’d buy a big boat and try to investigate the icy edge of the flat earth, somewhere besides South to “Antarctica.”    Is this impossible?  Has it been done?  Why not?

Our government is telling us that Antarctica is a Continent but we believe it is the entire perimeter of the Earth.  Is there no place else a boat could head to see what is at the “Edge” in a different location? 

If this is a dumb question, tell me so and why and I’ll delete my login.  Many thanks.
