I would imagine this would be fake in the eyes of the FE'ers

Yea and the gov't put conspiracy lenses on all types of cameras to only make the horizon appear curved

I really don't see how the FE'ers can say that everything is fake/distorted. Not every lense makes things only farther away than a mile appear distorted. My camera doesn't. Convenient how every camera is defective don't you think?

yea and they think when you post a pic of the horizon, they think the actual horizon spans across about 50 or 60 feet

because they all fled to their FE cave were they are trying to make it so that they don't contridicte eachother every other post

I suggest you do a mathematical calculation of the amount of curvature visible at some altitude.  It's been done many times on this forum.  You should do it yourself if you can't search or don't believe anyone else.

I did do it myself, why dont you search my posts

The height of a spherical cap (as depicted below by the "small circle" image) with a small-circle radius of 4 miles and a spherical radius of 4000 miles (8000 mile diameter) is another easy Pythagorean triangle:


You're gonna have to ignore the 'a' on the second picture there.  it should be 't'. 

Using equations from my previous post to find 't' (shown as 'a' in the picture):

t = sin[atan(r/s)]*s

Pythagorean triangle of side 't' and hypotenuse 'r' to find 'h':

h = r - sqrt[ r^2 - t^2]

then multiply by 5280 to get feet yields:

h=10.0 feet (mathematica file available)

side note:  Notice how h is exactly the same as 'a'?  This is the exact reason why the height of a person is negligible compared to the size of the Earth.

That means that you, at an altitude of ten feet, are a total of 20 feet higher than the plane of the horizon.  Keep in mind the horizon is 4 miles away.  That is, 21,000 feet away, which puts the horizon at a declination of:

arcsin(20/21120) = 0.05 degrees from the horizontal.  Looking up, the sky takes up 180.1 degrees of your field of vision.  You are not going to notice that curvature. 

If you don't think that angle is very small, take out your protractor and try to draw two lines 0.06 degrees apart.  They will end up looking like a single fat line on one end (even if your protractor had that great of precision).  That is because 20 feet is very small compared to 20,000 feet. 

That is why one cannot ever hope to notice the curvature of a round Earth by just looking at the horizon; it is negligible.  The Earth is huge, and we are not.

Firstly, you are aware that flying over the north pole is perfectly possible on a FE, yes?

Second, those are some nice pictures, but the curvature in them is nothing more than a trick of the camera, as no curvature is visible whatsoever from that altitude.

I think you fail to appreciate just how big Earth really is in either model.

you too are also and idiot

for about every 5 miles, the earth 'drops' about 16 feet i think where you see the curves is well over 5 miles long

Doesn't Earth drop about 8 inches per mile. 16 feet drop every 5 miles is way to high.

oops, i must have read some false info
