How can we prove that the earth is or isn't flat?

-------------------------------------------------------

Harry Buttcrack say: Even idiots know the world isn't round.

It's spherical.
-
Phillip say: The Phoneticians knew the world is round over 3,000 years ago. Sorry you are so far behind.
-
fay v say: Nothing... Idiots are just going to believe what they want to regardless of the facts.
-
small say: Easy...... keep walking straight in the same direction and finally you will reach the same place from where you started...... this you can repeat starting from various other places and every time you would finally reach your original starting point....... this proves that the earth is spherical and the ground forms the outer surface of the earth.

7Flightsup say: That's not an issue when anyone can see through a telescope that all the planets in our system are round, and Earth is just another planet that goes around the sun like the others.
-
All hat say: Twenty ways - everything from how they first did, ships coming over the horizon, to now space satellites which can simply snap a photo of it.
-
USAFisnumber1 say: 1. Satellite images. 2. The fact you see the top of a ship coming at you instead of the whole thing. 3. The fact the sun does not rise at the same time around the entire world. It is far easier to prove it is not flat.
-
Johns say: It's already been proven it's round, photos from space and other proofs
-
daniel g say: Already proven. And quite a long time ago.
-
RR say: How is your spherical trigonometry? A triangle inscribed on the surface of a sphere has internal angles of more than 180 degrees.

All surveyors know that if you observe a large triangle on the surface of the Earth it has internal angles greater than 180 degrees.
-
Bill G say: Look at photos of Earth taken from space.
-
stephen say: Go into space, soon.
-
elj2017c say: I'm thorough convinced from what the Bible has stated. The Hebrew prophet Isaiah stated with remarkable simplicity: “There is One who is dwelling above the circle of the earth.” (Isaiah 40:22) The Hebrew word chugh, here translated “circle,” may also be rendered “sphere.
In the book of Job, we read: “[God] is stretching out the north over the empty place, hanging the earth upon nothing.” (Job 26:7)
The picture conveyed of a round earth ‘hanging upon nothing’ in “the empty place” reminds us strongly of the photographs taken by astronauts of the sphere of the earth floating in empty space.

Curtis Edward Clark say: We do not have to prove that it is not flat. That was proven 500 years ago. Do you want to start doubting it now?
-
♜Ⓢⓚⓨ ❍ Ⓓⓞⓥⓔ ♜ say: The Earth is not perfectly round or smooth. One may say it is made up of many flat surfaces which seem flat to an observer on the ground.

But should he climb a mountain he may gather it makes a contour in the horizon that is not infinitely distant nor hidden in an infinite haze.

And if he went up further on a balloon it would become more obvious. It is there for anyone to see if he has the technology.

It is in a agreement with established scientific models of how physics works.
-
jehen say: It has been proven the earth (as are all large bodies in the universe) is a sphere in countless ways - mathematically, scientifically, astronomically, photographically, not to mention and the everyday experience of circumnavigation regularly occurring since the days of Magellan 500 years ago. As that appears to be insufficient in your mind, there is nothing that can prove it to your satisfaction.
-
Mike W say: Pythagoras proved that it's round some time around 500 BC.
-
geezer say: Go up into space and look.
-
Nyx say: This was settled thousands of years ago dude.
Time to move on.
-
Lord Percy Fawcette-Smythe. say: A recent statement from the 'Flat Earth Society' said "We are getting more and more members from all around the globe" Flat Earth? globe?
-
Bill-M say: There are at least 100 ways to prove the Earth is Round and ZERO ways to prove the Earth is Flat.
1. Time Zones
3. The fact that you can fly or sail around the world
Just to name three.
I will explain time zones> There are 24 main time zones around the world.
You live in New York City and have a very close friend you trust in Honolulu Hawaii.
At the exact moment you see the sun rise you call your friend in Hawaii and ask him if he sees the Sun Rise. You stat on the phone with him until he does. You will be waiting several hours.
If the world was Flat the Sun rise in NYC and Honolulu would be at the same time.

-
David say: The Bible says the earth is ROUND (Isaiah 40:22, KJV). Case closed.
-
∅ say: gee, maybe if someone flew around it in space and looked at it from every possible angle and sent pictures back of how it looked round from every angle...
as a counter-arguement, how can you prove a basketball is round?
-
Who say: Easy - just look at a ship sailing directly out from the coast

It will get smaller and smaller

THIS IS the key thing

If the earth was flat it would just continue to get smaller and smaller until you couldnt see it any more

BUT IT DONT
the bottom of it starts to disappear while you can still see the top of it
more of the bottom of it disappears until you cant see the top at all

this PROVES it CANT be flat

And the rate at which it diappears proves 2 things- It MUST be round - and if you know 4 things

1) how fast the chip is going
2) how high you are above sea level
3) how long it took to disappear
4) how high the ships is above sea level

you can calculate how round the earth is

Robin W say: There is a live feed view from the space station: https://www.youtube.com/watch?v=4993sBLA...

Choose a bloody best answer. It's not hard. say: I love your use of "we".

If the Earth were flat the sun would rise everywhere at the same time.
-
Barry say: A ship on the horizon appears to increase in height approaching and reduce in height moving away. This proves curvature of the Earth. Of course there are also numerous pictures of Earth from space.
