No, the earth is not flat.

Diagrams are not images seen through a telescope, and certainly are not naked-eye observations.

Again, a statement of fact, but what are you implying? That we can see more than the one side of the moon? Show the photographs to back up what you were implying, unless you really were only posting a fact irrelevant to the point being made,

Neither, and I am not obligated to support assertions I did not make.

Lol. Just an irrelevant fact, then, as if to demonstrate to the naive that you had a ball-Earth response that actually countered my argument, when indeed, you had nothing, and would have been better off remaining silent. If only your geometry skills were at the same level as your debating skills.

My geometry skills and my debating skills are both quite adequate, thanks very much. That you disagree with me is no reason to insult my intelligence. Given that you clearly don't understand my point, perhaps you should question your own.

You're trying to change the subject. The offer was there to explain why you offered up the fact. You were trying to appear as if you had a ball-Earth theory answer, when you don't.

You make too many assumptions.

I explain tactics for the more naive.

It's not "my" claim, it's the claim of all Concorde crew, passengers, and Blackbird and U-2 crews, astronauts, and now even space tourists can see the curvature too, surely they can't all be mistaken?..

Trigonometry was invented for exactly that reason, to calculate dimensions otherwise impossible to measure. Typically, it was heights. It works.

Yes, people made observations that suggested that the surface of the earth was curved. Maths proved it.

Where do you think the map of the earth comes from? It was by actual observation. FE maps? There are none.

Software development on custom hardware that was developed in-house for this project. I specifically coded the math dealing with the earth's curvature. It took extra sustained work to optimize the computationally demanding curvature related code to meet the military grade specs. Actual fighter jet pilots have to approve the results so it must look realistic to them.

Getting the shape of the earth right certainly isn't as important as loving our brother as ourselves.

Trigonometry is good for a lot of thing - as long as you don't base it on bad assumptions...

Another assumption: that you are less naive than others.

Every map in existence that is the result of actual measurements is a 'flat' map - derived from three-dimension topography. Other maps may be the result of taking a 'flat' map and wrapping it around a spherical shape - but - that is not 'measured' - it is manipulation of data to fit a conceptual model or pattern.

Au contraire. I don't recall you pointing out the covid hoax back in '20 and '21. So probably less naive than you. Or not, and you just don't care about Communists taking over the world with a fake virus, or people poisoning themselves to death with a dangerous bioweapon.

My, what a short memory you have. Do you not remember we refuted these poor ball-Earth arguments but a few months ago. Decided to bring out the old canards for a new audience, eh?

Sure, 90% of Australians have been vaccinated. The streets are littered with dead bodies because we don't have enough room to bury them. I can't open my front door because there are dead bodies piled up in front of it. And we have been told that the vaccination will kill almost everyone by the time they reach 100.

You have refuted nothing at all. Saying "you are wrong" is not refuting anything. Old facts and old truth do not change just because they are old. Perhaps you live on a different planet because yours is nothing like the earth.

I came across a video with "flat earth Dave" in it, and he was using concave hollow earth proof, to prove the earth isn't convex. Well, I suppose concave hollow earthers are being listened to by flat earthers, so our voices are not being completely ignored. lol

One last thing, it will be a complete circle when flat earthers switch to concave hollow earth view point, in my view, because flat earthers made me question the Heliocentric model, or at least wonder why flat earthers are crazy.



I like the sentiment here wolfwint, but some don't believe the earth is a planet. Concave Hollow Earthers believe the earth is the universe, and stars/heavenly bodies are all contained inside the earth. Anyways, you seem pretty balanced on your views. Enjoyed reading some of your posts.
