To answer the titular question;

If you like scientific articles: a simple search returned S. Frank and K. Tauber (2008): On the implicatory notion of an elliptical curve, Elsevier journal (

TL;DR a curve is like a bend.
An oblate spheroid is indeed like the shape in the image, but with a much, much smaller semi-axis oblateness.

There are billions of pictures of the earth.

But there is exactly ZERO pictures taken of a flat eart from more than 100 km above the ground.

Explanation: Earth is not flat...

Here is one

You can go pretty high, but dont expect to see the entire Earth at once. Also, not all the Earth is in sunlight at the same time so the rest gets very dark to see

Ehrm, isn't anyone going to mention that this image has a horizon, and doesn't continue forever or have an ice wall &c? This image seems to prove round earth. Assuming those clouds are cumulus, this image must be about 30km up (weather balloon?), which gives a distance to the horizon of about 173.2km from the perpendicular intersection with the ground. That's a 1.5-degree curve we should see. That's nothing.

Now, once you are ready to shatter your beliefs;
wait for a non-cloudy day. Look at the ISS on Pick a sighting opportunity with a high EZ, and do it at nighttime (also, as low magnitude as you can get--that's the brightness in the sky). You should see it as a star-like thing moving quickly through the sky--not as fast as an aeroplane but relatively fast (~5 minutes to go overhead). Try it. I have, I saw it with my own eyes. It passes every 90 minutes, although at slightly different inclinations due to the Earths rotation. Isn't science beautiful?
