Well.....I was in the US Navy and we certainly knew the earth is a globe and we certainly didn't use any flat earth maps for navigation.
Why being in the navy convinces you we live on a globe? I too was in the navy stationed on a ship for six years and i'm not convinced we live on a globe. If you where to remove all you ever heard about NASA, would you still be convince you live on a globe based on what you observe around you? If so, can you please give me some examples?
It is really useless to debate the point with flat earthers. I really believe there are really no real flat earthers on this forum . But here are some things for you to ponder.
Just one example of being in the navy would be enough to convince me we live on a globe.
You are the first person who served in the navy that I have ever heard that was not convinced that that we live on a globe.
Here are some things for you to ponder.:
The one word was "The Horizon"
Flat earth says that the horizon is just an indistinct blur that fades away in an infinite distance.
Round earth says that the horizon is a distinct line where sea and sky meet on the ocean.
Due to the curvature of the earth the distance to the horizon depends on the height of the observer and can be determined by a simple formula. The higher you are the farther you can see to the horizon.
So, when you were in the navy, didn't you ever observe the horizon ? Or did you ever wonder why the crow's nest or certain types of radars were mounted on the highest masts on the ship ? Did you ever ask a Radarman (RD) why the range on some of his surface search radars was limited by the curvature of the earth ? Didn't you ever ask a Petty Officer or a Commissioned Officer how those flat oceanic charts were made and what was their source ?
One more thing. Did you ever notice that when you sailed out to sea, after a while you could no longer see the land ? And that if a ship sailed over the horizon if you looked at it through a telescope you could no longer see it at the point where it disappeared over the horizon ? Did you ever notice that the hull disappeared from view first and the last thing you saw before it disappeared was the top of the highest mast ?
I'm surprised if you really were in the navy why you would have any doubts about the earth being a globe.
If you will just think about it or do it yourself, I don't see why you would have any doubts that the earth is a globe.
I served in the navy for just under four years. But only about three years was actual sea duty due to time spent in boot camp and technical training. My highest rating/rank was only as an ET1 so I am not claiming to be any expert on the subject.
And finally the bottom line is simply that there is ample credible evidence that the earth is a globe and absolutely no credible evidence that the earth is a flat disc surrounded by a ring or wall of ice and covered with a dome of ice.....and a few other flat earth fantasies , et cetera , et cetera and so forth.
Incidentally, if it is any consolation to you
jroa I am thinking of abandoning this website. After a while it just gets boring from hearing all the flat earth replies over and over, ad infinitum , ad nauseum. ("Denial", "Fake", "Round Earth Conspiracy")So I will apologize to you personally and all the other flat earthers. I know I have probably been a bore to you, too. I won't promise this post will be my last.
I'll probably stick around just for the fun of it like a lot of others.
