That's really cool but looks like it's talking about a dome made of ice

Not a firmament dome but an ice structure

Nobody calls a mountain a dome..

Cuz it’s not a dome

Well it's a dome of ice

On a mountain

Because the mountains are taller than 13k feet

It’s all speculative anyway.

Even in Antarctica

Point is, a flat earth doesn’t need to disprove what can’t be proven. Aka, curvature.

But it can be proven

No.

How can we prove curvature? That is the entire question

Well if you do any amount of research from a credible source than you will see that the earth is not flat

Nasa isn’t credible?

I'm bored, I wan't information about earth and NASA

That is interesting that they specifically emphasize a flat non rotating earth for airplanes and helicopters

Gee, no kidding.

So I was looking up salt flats as proof of flat earth because they are huge expanses totally flat

But then what I found said they prove curvature

"Once there, go the speedway track starting line.  Take a picture of any car parked there.  Then head out over the track.  At about 3 + miles away look back, and you will notice that all those cars and structures at the starting line are no longer visible.

Take a pair of binoculars or a small telescope with you on that trip.  So that you can look back and verify that all is gone - hidden beneath the curvature of the Earth.

And you need to make sure you travel the entire 10-miles of the track.  Then look back, once again at "starting line," (which is not visible).

Congratulations!  You have now proved to yourself that you live on a globe curved Earth."

@Green Knight optical slant. Angular resolution

Why can’t we see Africa from Florida?

@waffleking angular resolution. And visibility

What does that mean exactly

WHAT CAUSES GREAT VISIBILITY?

I want you to explain it to me not some YouTube video

This is basics information of how the human eye or lenses work and how light works

So there can't be a firmament because meteors get through

The human eye has an angular resolution of .02 degrees

@Green Knight <#538929818834698260>

We have telescopes that can see hundreds of thousands of miles into space. Why can’t we see Africa from Florida

Visibility

Too much dust and stuff in the air

Can you see the stars when its cloudy?

Plus...

You just asserted the stars hundreds of thousands of miles away. Might be true. Might not be.

So are we saying all the images of galaxies and nebulae and starfields etc are fake?
