Where is the edge of the world according to flat-earthers? The answer changes, but it usually involves some impenetrable barrier at said edge that prevents people from going past or falling off. Global conspiracies apparently prevent people from investigating these boundaries yet no one has ever seen this huge barriers that go around the world. humans have circumnavigated the planet in planes and ships, and no one has fallen into space. Rather, when ships traveling large distances on the ocean do appear and disappear on the horizon, they do so either mast or hull-first, respectively. If the Earth was flat, and you had the right optics, you could watch a ship sail from New York to Africa without losing sight of it.
Hit up a friend in Australia and ask them what constellations they can see at night. Now tell them which ones pepper your patch of darkness. They won’t be the same. Because the Earth is a shape other than a flat disk, when looking into the night sky the Earth itself can block your view.
If the flat Earth theory were true, everyone should be able to see the same constellations all the time, as if we all were staring up from the same section of summer grass.

Show us a picture or a plane flying besides the sun, since you think it's so close, it should be pretty easy no?

The train's destination is not above the ground, but rather far away, and perspective means that the tracks appear not to be parallel but instead to converge to the vanishing point.
The same applies to the beams of light above them. The Sun is very far away and the beams are pretty much parallel, but they're pointing towards you, and perspective makes them appear to converge towards the vanishing point - which in this case is the Sun's location in the sky.

^^^ Perspective doesn't splay vertical lines you schmuck, you're a fucking idiot! I asked for proof and you've failed to provide any and you've made the false claim that perspective causes vertical lines to converge.
Here, I've highlighted the part you're intentionally ignoring or simply can't get your head around.
Nice pictures and explanation Astargath, unfortunately you stand a better chance of teaching a cumquat algebra than getting through to notbatman.

So the sun is hiding behind the trees then? How is it illuminating half of earth when the sun is just hiding behind some trees?
Sunset question:
So we would all see the same sunset if....
Apart from ones elevation (on a mountain or something), wouldn't we all see the sunset at the same time (or about the same time, not staggered as we see it now, divided over a whole day) if the world was hmm "flat" ?

Q: "determine whether an image is real or not"
A: "A digital camera equipped with a processor for authentication of images produced from an image file taken by the digital camera is provided. The digital camera processor has embedded therein a private key unique to it, and the camera housing has a public key that is so uniquely related to the private key that digital data encrypted with the private key may be decrypted using the public key. The digital camera processor comprises means for calculating a hash of the image file using a predetermined algorithm, and second means for encrypting the image hash with the private key, thereby producing a digital signature. The image file and the digital signature are stored in suitable recording means so they will be available together. Apparatus for authenticating the image file as being free of any alteration uses the public key for decrypting the digital signature, thereby deriving a secure image hash identical to the image hash produced by the digital camera and used to produce the digital signature. The authenticating apparatus calculates from the image file an image hash using the same algorithm as before. By comparing this last image hash with the secure image hash, authenticity of the image file is determined if they match. Other techniques to address time-honored methods of deception, such as attaching false captions or inducing forced perspectives, are included." -- http://www.patents.com/us-5499294.html

All the photos this guy made have to be real, right?
That link doesn't have any pictures, just a bunch of smart remarks.
What? You missed (intentionally) the little "x" at the top-right of the page, that you can use to close the Twitter layer, so that you can view the rest of the site? Notice, I said "page" rather than "screen," so that you wouldn't accidentally close your browser, and have to go through the horror of re-logging in. Am I not just a considerate, thoughtful guy?
^^^ Fuck off, the camera is pointing up.
Hey! The camera doesn't care. It only takes pictures of what is there.
SHOW ME THE SUN'S RAYS HITTING THE EARTH IN PARALLEL!!!
What are you even talking about? Go out and look, yourself. Just because your focus is so off that you can't see them.
But remember. The atmosphere scatters the rays so that you can't see the parallel way they hit the earth's atmosphere.

Are any of you flat earth nutters gonna explain why things fall to the ground, or are you just gonna keep changing the subject and shifting the burden of proof?
I've answered the question many times.
Edit:
I'll recap for you...
The reason objects fall is because they're denser than the air or whatever substance surrounds them. The object displaces the air and the air reacts by pushing the object down. It's more complex than just the air pushing on things but that's the basics of why things fall.
Not-Robin's-buddy, notbatman, must be extremely fat. Why? He is so heavy because he is extremely dense.
Don't get caught up in his Reductio ad absurdum.
It's my quest from now on to convince notbatman to stop believing in nonsense and accept that the earth is not flat.
OK you can start by proving the Sun's rays hit the Earth in parallel. You claim Eratosthenes theory is correct, now fucking prove it!
Here are some of the points that mess with your idea of the sun having or not having parallel rays, and with your picture, above, which I re-posted below. Let's look at the picture, first.
1. In the picture, the rays that look like they are straight down near/at the center of the picture, really are not. Rather, they are slanted towards the camera, but maybe away from it. They look straight down because the slant towards/away-from the camera isn't apparent.
2. Further on #1: Assuming the picture was taken at high noon, a picture taken from the right extreme of the horizon (actually, farther to the right on the horizon; also at near high noon), would show exactly the same kinds of rays from that vantage point. The rays that are straight down in this picture would appear slanted to the left or right from that vantage point.
3. On the moon, we would never see any rays like these, because there is no atmosphere to scatter them at all. The whole picture, above, shows rays because of the light-scattering affect of the atmosphere and the clouds.
4. The picture proves nothing about parallel or non-parallel rays from the sun.
----------
The sun is approximately 100 miles wider than the earth. This means that some of the rays striking the earth would travel parallel to the earth. But other rays would be traveling at all kinds of angels to the earth, within a given trigonometric function of the distances between the sun and the earth. (Note that the various parts of the earth have slightly different distances to the various parts of the sun at the same time.)
There is, also, Bernoulli's Principle to take into account, which would actually straighten the rays out, making them parallel to each other.
----------
You are scientifically-minded enough that you know this. So, you prove yourself deceptive, and virtually a liar who deserves any bad rating you get.
