visually

I know

angular resolution limits

dirt and moisture in the air

Your optics have limits, but you should be able to see extremely far (in a theoretical world with no limitations)

is air perfectly clear?

I said “theoretical”

The firmament is round. like the earth was in a ball

so dostn apply to reality

Flat in the center of it.

refraction !!!!

mirage

....the earths is flat

Mirage can not be perfect. They are wavy.

This is such a lame excuse.

@rightthehand it does apply, I said you should be able to see extremely far. I meant that when you look, considering there is nothing blocking you and then I said “in a theoretical world” where there is nothing blocking you from looking.

You’re right @Steve Angell

It is a lame excuse

but in the real world the air isnt clear

Obviously

so then your therotical applications doesnt fit reality

This gotta be a joke

Where I live I can rarely see more than ten miles. The air is so humid and salty as near the ocean east and west.

My theoretical applications obviously don’t fit reality, but considering @Steve Angell ‘s applications to reality, he can see more than ten miles away. With such conditions, your applications really disproved themselves when @Steve Angell said that.

@rightthehand

So how does seeing 10 miles prove earth is a ball?

I'd like to mention a lot of the horizon pictures posted here end in a mountain range. While it does give you a point of perspective, of course it won't look as curved when a wall is in the way

Your horizon excuse is so lame. Consider the variables and probabilities. What if the ground below the camera was perfectly flat? What if the camera was not being held by a person, but a stand to hold it up? That would change your perspective. There is such a finite amount of probabilities, but every one can change one variable entirely. Also “seeing 10 miles” doesn’t prove the earth is a sphere, but it proves what I was saying before about horizons@ @rightthehand ...

Thank you @Doomyx

Again how are you proving the earth is a ball by looking around?@It’s Complicated!

As I said, it doesn’t, but it proves my point on horizons...

There are rare days when I can see much further. Up to around 50 or 60 miles if in the right places where trees are not blocking my view.

Brb

Have to go to my next class

What point on horizons?
