The first physical proof that the Earth is NOT FLAT was accomplished by Ferdinand Magellan and Juan Elcano

Saying it doesn't make it true.  A story, no matter how long its told cannot provide serious criteria against empirical proof.  Real time repeatable experiments pretty much dust this statement.  

Where has the Church taught that the earth is a sphere?

.
Pope Pius XII, for one, referred in his official writings several times to the "globe" earth. 
.
Are you claiming that a sphere is not a globe? 
.
You can see in the ISS video the way water droplets in zero gravity conform to a globe, or spheroid shape. How do you explain that appearance? All CGI, Photoshop and fake, eh?
. 
Okay, if it's so simple to fake it with F/X, why don't the flat-earthers make a video showing how a water droplet in zero gravity conforms to their "flat-earth" model? Simple, no?
.

"Biruni's estimate of 6,339.9 km for the Earth radius had an error of 0.0026 and was 16.8 km less than the current value of 6,356.7 km."

His estimate is impressive in that it was made over a thousand years ago.

It's not really that impressive considering the ancient greeks had pretty advanced maths.
I need to explain to the honest people reading this though how this does not prove the round earth. Calculating the circuмference of the flat earth is possible because the sun has a fixed radius over 24 hours, going OVER the earth.
If you impose spherical trigonometry on top of this you come up with a RADIUS of and imaginary globe earth, mentioned above. But this is total fantasy. It presumes the earth is a globe. It is just turning numbers into other numbers by putting them into equations. It doesn't bear any relation to reality.
I am happy in a way that you brought this up, because it gives another occasion for the truth to shine even brighter.

JohnAnthonyMarie is getting worried.
What are you afraid of? Facing the truth?

as for the images below, we don't deny that items merge with the horizon, but that is all it is. This still doesn't explain why we see objects we shouldn't see.


The globe trolls are out in full...

Yes, let's start a riot!   Burn the flat earthers!   :heretic:

Neil,
Just for the sake of everyone reading these posts, and so you can show there is no conflict of interests, can you you confirm whether or not you work for NASA?
You don't have to say where or what department, because it is a very big organisation, I just think it would be good for people to know so they can be objective in judging your arguments.
Pius XII? The same Pius XII who gave us the '58 Holy week? Don't you have anything a little more older than that, since everybody knew the earth to be round, as you claim for a lot longer.
Kind of hard to bring up advanced CGI when we're not in possession of the expensive equipment necessary, not the training in CGI, nor the time. But this is the same tactic you use against flat earthers all the time; being to make unrealistic ridiculous demands of them in an attempt to make them look stupid and you smart.
It's not arrogant people coming to flat earth btw, but humble ones. The arrogant will never accept it.

.
Do you think someone must work for NASA just because they can compose cogent sentences?
. 
And you're a pre-Pius XII sedevacantist, I presume.
.
You don't need CGI to measure an angle between two objects in the sky. Just get a protractor out. 3rd Grade level.
.
It's the flat-earthers who make the claim that it's so easy to fake the videos from ISS, so why can't they prove their claim? Okay, if it's so simple to fake it with F/X, why don't the flat-earthers make a video showing how a water droplet in zero gravity conforms to their "flat-earth" model? Simple, no?
.
If I look "smart" all you have to do is show me where I'm wrong and I'll look not so smart. Your turn.
.
In 3 weeks millions of people will line up across the USA for the biggest solar eclipse in US history.
Are you going to say they're all wasting their time because it won't happen?
Or are you going to say that it must be a faked event staged by NASA just to make the flat-earthers look stupid?
If it's so easy to fake an eclipse why can't the flat-earthers do it too?
When has any flat-earther been able to predict an eclipse?
Or what flat-earther can even explain what causes an eclipse to occur  in the first place?
.
This is all so obvious it isn't funny.

Saying it doesn't make it true.  A story, no matter how long its told cannot provide serious criteria against empirical proof.  Real time repeatable experiments pretty much dust this statement.  

(That was replying to JohnAnthonyMarie's post)

Dear JohnAnthonyMarie, the flat-earthers do not recognize the technology of celestial navigation used by sailors for the past several hundred years. I have posted some very good videos on how dead reckoning is accomplished at sea, which is very interesting to say the least, and the best they can come up with is stuff like you see here,
.
"Saying it doesn't make it true.  A story, no matter how long its told cannot provide serious criteria against empirical proof."
.
BTW no better example of empirical proof could there be than sailing a ship using dead reckoning to verify position at sea.
.
Flat-earthers have no idea what empirical proof means. The fact that an experiment is REPEATABLE and therefore verifiable, is an essential element of empirical proof. Flat-earthers like to copy key words and use them out of context for their meaningless diatribe, which exposes their ignorance. It's pretty embarrassing.  :-X

I'm glad his comment was deleted, it was WAY out of line.  Hopefully he has been banned.

.
He continued to post, but not for long. He couldn't stand the heat so he left the kitchen.
Flat-earthers don't get to run rampant with their malicious trolling here as they would hope to.
