Why this dicsussion? Are we back in middel Ages?
The discussion is quite interesting actually, he is asking for an experiment that anyone can do to prove to themselves that earth is not flat, wich might not be that easy to find.
Yes. It's very interesting. They prove their opinions about it.
How about you? Do you believe that the earth is a flat one?
I know she is flat. Density sorts everything including water (always will seek lowest point, there is no such thing as a mountain of water).
