if you really want to know if it's flat or round.. just go to the outer space and look it yourself. 
Many people doesn't believe on this, but it was proven many times that the earth is round! Hope that helps!

No, no it doesn't help. Outer space is a hoax and there isn't a single shred of credible evidence we're on a spinning ball in a vacuum. Every so called "proof" of a globe is based on manufactured evidence, logical failicies, baseless assumptions and conflating facts.
Every single experiment you listed has been debunked, even by their authors. They are not facts, they are garbage discarded experiments that were proven wrong. You are a proven liar, sorry.
