So let me get this straight. According to your numbers of a circumferance of 78,000 miles which we will assume are accurate for purposes of discussion, everything would be much further apart in order to still even take up the space on earth. So let's say you are getting on a boat to go to, oh, I don't know.... let's say Austrailia. RE'rs will tell you that it is let's say 3000 miles. You also know that a mile is 5,280 feet. You can physically measure how many feet a minute are being traveled. Let's say you are traveling at 10 miles an hour, it would take you 300 hours to travel that distance. So it would take you 12.5 days. However, if you use the circumferance of 78,000 miles the distance is roughy 7 times squared farther. Roughly 49 times farther. So what would take you 12.5 days would suddenly take you 612.5 days traveling the same speed. So is it an illusion or is the boat that we measure traveling 52,800 feet a hour really traveling 49 times faster?
First you claim Australia is 3000 miles away (away from where? I don't know), so it would take 12.5 to get there traveling 10 mph.
Then you say it would take 612.5 days to travel 78,000 miles.
I fail to see any correlation between these two claims, or any bearing as to whether the earth is flat or round.
I assure you, there are places on the flat earth that are 3000 miles from Australia.
Now, because I have a vague idea of what you might have been intending to say, I'll respond as though you made the following claim:
On the round earth, Australia is 3000 miles from Chile, and so it would take 12 days to sail there at 10 mph. On the flat earth model, Australia would be much further; a significant portion of the flat earth's 25,000 mile diameter, so 15,000 miles or more. This distance would take 60 days to travel at 10 mph.
So on a round earth it would take 12 days to get from Chile to Australia, but on a Flat Earth it would take 60 days.
How do you account for these discrepencies?
In response to a question of this nature, I say assert that the trip would, in fact, take 60 days, and the 12 day figure it different because it relies on the spherical nature of the earth, and so is wrong.
Until you can prove otherwise, I will continue to assume Australia is 15,000 miles from Chile.
