How can you prove that the Earth is not flat?

Question

I know its hard to present reasoning without some sort of bias. Pretend that you never knew that the Earth was round. What would people have to say to make you believe?

Well,I don't know how a three year old could prove it wasn't flat. People back then would think you were crazy if you gave them a picture with Earth on it and said "theres proof it isn't flat!" But then, isn't the paper itself flat? Also, they've never heard of satilites.

I myself believe that the Earth is round so for all those imbeciles out there who think I'm the one who thinks its flat, then their wrong. And consquently get a thumbs down.

Others did quite great. Supported their evidence. Displayed LOGIC...hint hint. I now know who to pick.

Never give up.

A question to those who have actually seen pictures from space: "Have you actually seen the Earth from space?" Hmm. There something called PHOTOSHOP. I could probably make pictures of Martians walking on Mars and people would still believe me! I'm not saying NASA is a waste of money and a scam, I'm just saying, have you ever had that personal experience, ever been in a space shuttle and knowing that the Earth was round?

Answer 1

1. Travelers going south see southern constellations rise higher above the horizon. This is only possible if their horizon is at an angle to northerners' horizon. Thus the Earth's surface cannot be flat.

2.The border of the shadow of Earth on the Moon during the partial phase of a lunar eclipse is always circular, no matter how high the Moon is over the horizon. Only a sphere casts a circular shadow in every direction, whereas a circular disk casts an elliptical shadow in most directions.

3.When sailing towards mountains, they seem to rise from the sea, indicating that they are hidden by the curved surface of the sea.

Answer 2

Look at the shape of the sun and the moon, both round. It wouldn't take a rocket scientist to figure out that at least the moon is a ball, can be demonstrated with a kids ball and a light. Maybe a coincidence, but probably not.

Answer 3

There is at least one place where you can show it is curved, if not spherical: the Causway Bridge, between Mandeville, (pronounced MAN-duh-ville) LA and Metairie, (pronounced MET-a-ree), LA. Travelling south on the bridge you will notice New Orleans "rising" from Lake Ponchartrain (forget the first 'r'). Also there are so called "high-rises" on the bridge (to let boats go under), and on these you can see easily the city rise above and then fall below the horizon. It is very spectacular at night.

Answer 4

The greeks figured it out, their evidence would be enough.

Basic observation that a ship on the horizon slowly sinks away, you can see its mast while the hull has dissapeared

The earths shadow during a lunar eclipse is round....

or a photo of the earth from space, that works too

Answer 5

1. No one in recorded history has walked off the edge of the earth.

2. Satelittes in space have pictures of the earth as a SPHERE!

Answer 6

If you dont know how to do so mathamatically, ect. then the easiest way is to travel in one direction, say west. keep traveling west until you either A: End up back where you started(ah ha you now know its round!) or B: you fall of the edge. then you would know it was flat.

Answer 7

Have you ever walked off the edge. When a boat floats off into the distance it gradually gets lower till you can not see it. Satellite pictures.

Answer 8

Any three year old could do it. Get a big square hole and try to put it through. It won't go. Next, try the triangular hole. Same result. It will ONLY fit throught a ROUND hole. Therefore, the earth is round.

Answer 9

Well, I had an email chat with someone from New Zealand once. I asked him, "Hey, is it dark where you are right now?" He said, "Yeah".

That may not be the most rigorous proof, but it certainly supports the argument. :)

Answer 10

You can look over an ocean (horizon) and watch a ship sail toward or from your direction in a straight line????
