do a model of a ball and you being on it

no matter how big the ball is and how small you are, you'll know its curving

you can test it and see it

everything is flat

No, I want you to understand that:
**on a flat plane, if the camera is above the plane, there is nothing to block a ship on the flat plane in the distance.**

@Moist Mayonnaise is that true? ^

Yes, completely

Thank you.

I know more people != truth

you totally miss the point

the human eye can only see so far, unless the atmosphere is right conditions you can see roughly 3 miles at best

@Fireflash - not true

if you go higher you can see further

from the ground 3 miles roughly

The human eye can see forever, theoretically

unless you zoom in, this is on flat earth

nope
@Fireflash

you can see lights in the distance

that are many more miles away than 3.

the human eye cannot see forever

I can see a plane in the sky

that's 7 miles up ;P

how small is it

with just their lights

a cessna

put it 21 miles up, how much smaller is it?

put it 300 miles up, you won't be able to see it

@Goldsteel - Dont be misconstrued by other "FEers"
we dont mean Exactly always precisely up to "eye-level"

-- They're/we're being approximate there
.

you got a plane only 300 miles away and you can't even see it

because the curve hides it

you really think you can see forever when its only 300 miles away and you can't see it

:dab:

wtf

imagine how big the sun is when its 3,400 miles away and its that big

what happened to my nitro

@Goldsteel "Stars" are close -- uhm so what?

they're not trillons of Lightyears away

luckily we can see the sun with our limited vision

i nose dat i nose

dats how

** stick with refraction plz**

I need some explanation for this image: https://qph.fs.quoracdn.net/main-qimg-a04c6df7269268394ce2348d6476bf22-c
