The higher you go, the further you can see

Changing constellations
This observation was first made by Aristotle, who declared the Earth round by observing the change in constellations as it crossed the equator.

Returning from a trip to Egypt, Aristotle noted that “stars are observed in Egypt and Cyprus that are not seen in the northern regions.” This phenomenon can only be explained by the fact that people look at the stars from a circular surface. Aristotle continued by stating that the sphere of the Earth “is of small dimensions, otherwise the effect of so slight a change in terrain would not be so rapid.”



The further you get from the equator, the further the "known" constellations move towards the horizon, being replaced by other stars. This would not happen if the world were flat.

Shadows and sticks
If you stick a stick into the ground, it will cast a shadow. The shadow moves with time (based on this principle, ancient people invented the sundial). If the world were flat, two sticks in different places turkey number data would cast the same shadow. But this does not happen. Because the Earth is round, not flat.

Eratosthenes (276-194 BC) used this principle to calculate the circumference of the Earth with fairly good accuracy.




Standing on a flat plateau, you look towards the horizon away from you. You strain your eyes, then take out your favorite binoculars and look through them as far as your eyes can see (using binocular lenses).



Then you climb the nearest tree — the higher the better, the main thing is not to drop your binoculars. And again, straining your eyes, look through the binoculars at the horizon.

The higher you climb, the further you can see. We usually associate this with obstacles on Earth, when you can't see the forest for the trees, and freedom behind the stone jungle. But if you stand on a perfectly clear plateau, with no obstacles between you and the horizon, you will see much more from above than from the
