Hi douglips & StinkyOne, thank you for your reply. The centrifugal force is not my problem, this is something I pondered enough when I was young.
Since this FE topic is coming a long way and the theory of the ice ring or wall, logic tells me that sailors who explored the oceans in the past must have documented their encounters with the ice ring when they sailed along the equator of the ball earth. There must be archives with this information somewhere.
I see that people do all sorts of experiments to prove the flat earth, some of these experiments are really interesting and this is why I want to find out more about the topic.
I think to prove that the ice ring/ wall really exist is a small step in the right direction. This is something that should easily be observed, because if you travel south on the ball globe you reach Antarctica. You should reach the ice ring when you sail or fly along the equator on the ball globe or parallel with the equator,lets say directly from Australia to Chile. What I find is that no one seems to be able to get solid prove of this , but rather try to make assumptions on what the earth should look like from very high up in the atmosphere.
I will appreciate it if one of the moderators of this forum could respond to my question or point me to any information with actual documented information on this.( English is not my first language and if my question is not understandable please ask me to rephrase it)
