If you go around the equator and along a meridian you'll end up in the same place you started and you won't encounter any edges (you'll go in a circle), so the Earth can only be a spheroid.

Also moving to general.

Without mentioning NASA and other space agencies.

This is not a joke thread im just curious


Bacause physics and math, can easily proove it.

Its bascially possible to do with this 2 sticks each same lengh and shape, put into the ground and messureing the shadows.

You can also observe it, when ships sale out to sea.

Fun fact : Sailors in ancient greece already knew the earth was sphere like, because they could only see the upper part of faraway boat's sail.

edit : paint level over 9000

the same effect is possible on a flat earth.

People have circumnavigated the globe before, yes.

Actually, the Mayans were the first to discovered the earth was round. The figured the shadow cast over the earth by the Sun made the earth curve around. They also were the first to discover that the earth gravitated around the sun. But because we live in a Euro-western dominated society, books will not acknowledge the Mayan as an advance culture that discovered things before most European scientists. Btw, if indigenous population were savages, where did the corn come from? Corn is the only produce that cannot grow by itself so, was it created by the American people back then?

The temperature gradient between the poles and the equator is caused primarily by the Earth being spherical.
The Sun's rays hit more surface area in the poles because its curved.(near parallel 2 Sun), and less in the equator because its flatter(perpendicular). Since the heat is distributed over less area in the Equator, that heat is concentrated and its hotter. At the poles that heat is distributed over a large area, so it is diffused.

Also lunar eclipses.

This is the worst argument I've seen so far and yet everyone's been saying this crap. Look at Pac-Man. If you crossed the edge of the stage at the right, you would show up at the left side, and that wasn't round. It's obviously how the world works.

i say its gravity which doesnt make much sense to prove that its a ball.

i think i get all that ..but still dont see how it proves the earth to be round as you said 'curved' but not a ball not round a flat earth can also be curved.

http://en.wikipedia.org/wiki/Eratosthenes

He is best known for being the first person to calculate the circumference of the Earth, which he did by applying a measuring system using stades, or the length of stadia during that time period. His calculation was remarkably accurate. He was also the first to calculate the tilt of the Earth's axis (again with remarkable accuracy). Additionally, he may have accurately calculated the distance from the Earth to the Sun and invented the leap day.[4] He created the first map of the world incorporating parallels and meridians, based on the available geographical knowledge of the era.


Born 276 BC Cyrene
Died 194 BC Alexandria

Thats right more than 2000+ years of knowing the earth is curved, and its size.
This man 2000 years ago, came within 2% of the real messurements (used today).
