I mean, you can see the world is round by looking across the landscape and the curvature on the horizon. I think that this is an urban myth but I could be wrong.

Yes people actually believed that.

In a word, no.\nWhen you look that far away, you are looking back into time to the beginning of the universe.\nBut if the universe did originate from the big bang, i.e, a point source singularity, then all of the observable universe that far away was one point (or relatively close to it)!  So what would it really mean for the big bang to have come from a certain direction?  It came from all directions!\nObservations made that far away are made in the infra-red and microwave also.  It forms the 2.7°K background radiation.  This background radiation is not uniform, but it is also not as polarized as you may think. It does form the dipole anisotropy, but is not in general due to the big bang.\nSee:\nhttp://map.gsfc.nasa.gov/m_uni/uni_101Flucts.html

I think Saul of Tarsus was correct when he poetically observed that "we see through a glass, darkly". Our perceptions are a single mode of reality, but there are other modes that we cannot percieve directly, such as the world of the very small and the world of the very large. We must use the scientific method and instruments to enable us to indirectly extend our ability and percieve the things that we can't otherwise observe, but that do have a bearing on our lives nonetheless.\n\nI find it very interesting that the world of human perception is in the middle of the world of things, including size, velocity, temperature, and light, among other possible characteristics of the universe. The extremes extend to both sides of our perceptual abilities, both above and below. I think this is philosophically significant, but I have yet to ascertain exactly what that significance is.

their is one in (north burlington ontario) as well  .I have also read their is one in  Oshawa ,ontario, If you go to the bottom and place your car in neutral it drags your car uphil slowly .\n____________________________________________\nscientifically it is an optical illusion \nSometimes you may find or hear of a mysterious place where objects can apparently roll uphill. This is a remarkably common illusion which is found in numerous locations around the world. Usually it is a stretch of road in a hilly area where the level horizon is obscured. Objects such as trees and walls which normally provide visual clues to the true vertical, may be leaning slightly. This creates an optical illusion making a slight downhill look like an uphill slope. Objects may appear to roll uphill. \nSpots where the illusion is especially powerful often become tourist attractions. Tour guides may like to claim that the effect is a mystery or that it is due to magnetic or gravitational irregularities or even that it is a paranormal phenomenon which science can not explain. This is not true of course. Natural irregularities can only be detected with sensitive equipment and cannot account for these places but science can easily explain them as optical illusions. \n\nThere are several things which enable us to sense which way is up. The balance mechanism in our inner ears is one system we have, but visual clues are also important and can be overriding. If the horizon cannot be seen or is not level then we may be fooled by objects which we expect to be vertical but which aren't really. \nPeople often overestimate the angle of a slope. If you are standing on a slope of 1 degrees it will seem like a slope of 5 degrees. Because of this effect the anti-gravity illusion can seem stronger than it should be even when you know the cause.\n\nEven when the true cause is understood it can be difficult to believe. If you think there is a magnetic anomaly just use two plumb lines, one made of iron and one of stone. They would hang at different angles if a strong magnetic field was acting horizontally. \nHowever, it is not always easy to demonstrate that a slope which appears to go uphill is really going downhill. The only reliable way of determining the true horizontal is by careful surveying. If a good topographical map of the area is available it may be sufficient to show which way the land is really sloping. The results will confirm the illusion. \n...\nyou can also check the info I found on the Oshawa site \nhttp://www.shopinoshawa.com/magnetichill.htm

There are various things that you might want to read about, horizon theory & donut theory might be a good place to start. Much as we once thought the world was flat and we'd fall off the edge, but then discovered that is was round when we sailed from one side of the world to the other the same is thought (by some) to also be true about the universe, you travel in a line for long enough, you start off where you left off!

Could be a strange mirage. Sometimes weird mirage can project skyline of cities beyond horizon or just strange shapes in sky when atmosphere refract lights in unusual ways.

I've been out observing the sky many times as an amateur astronomer togehter with a lot of other ppl. We see many things in the sky, but none of them is hard to explain, especially not when you can look at them with good binoculars or telescopes.\n\nI classify ufo's to the other mass of "sightings" constructed by man or brain spawns... ie Yetis, Loch ness monsters, God, Leprechauns, Witches, Trolls, Unicorns, Dragons etc. Some of these things are perhaps funny to bring up today, but ppl have believed in them at one time or another.\n\nSo - in short - man is not a trustworthy witness. Eyes and brains are not the proof you need to establish an existance.

Not his original, but the image in the middle of the first link I'm listing is pretty close to Descartes' from De Meteorologica.  The second source has several modern takes on the image as well as a nice physical explanation of what is going on.

That's crazy dude... I see weird stuff out of the corner of my eyes too. I also sometimes get a glancing view of something, but it isn't really there when I look closer. We're both fucking nuts!

I think the world is round. Have you been outside of your room even? If the world was flat, you would be flooded, he he. Why are there mountains if the world is flat? Really you can't even answer my question? Try going to the library and actually do some research. Gotta go. Rock.

The further North you are, the more northerly the path of the sun appears as the summer approaches. It would be "south of west" only if the earth was flat.

Ha, good one!  The ancients belived that the sky was a solid dome (firmament), and the stars, planets, and sun were all attached to it and spun around on rails, or glass spheres.  This was, of course, proved wrong long ago by Copernicus and Galileo, the dawn of the space age only confirmed that their theories were true.

Bart,\nGood question bro, and the answer is fairly simple. As an aviator I've been from ground level to 35,000 ft and the reason why the horizon appears to be at eye level is something called 'Line of Sight'.\n\nThe earth is curved right? Well - to truly get a glimpse of the earths curvature your going to have to be well into the Stratosphere to notice that the horizon begins to go below your line of sight at those altitudes. Anything below that, the curve of the earth is going to intercept the angle at which you view it, and appear to be level at your level (the point where the earth's curve is in your 'Line of Sight'.\n\nHope this helped bro, take it easy out there.

It would apprear so in the book of Ezekiel when he describes the wheel within a wheel. However, the thinking on UFOs may be backward. Chuck Missler in his very well documented book "Alien Encounters" suggests (with scientific agreement) that what is being seen in the sky is actually a spiritual or cross-dimensional phenomenon. The Ezekiel wheel is actually a heavenly, angelic description, which may be in fact what others have seen as a UFO. Having seen one once in my life as a kid, I can definately tell you that it is amazing sight.

I went and did some investigation. It definitely looks to me like the Cydonia "pyramids" are real features on the surface of Mars. However, the question is, are these natural features, or are they artificial? \n\nOf course they might be artificial, and we won't know until we get more data. However, using Occam's Razor (i.e.,the simplest answer is the best) and erring on the side of caution, I would say that the evidence is that these are just natural formations (including the "face"; see reference). \n\nHuman beings are clearly wired for apophenia (also known as the clustering illusion; seeing patterns that are not really there), and in particular, for pareidolia (experiencing optical illusions). Humans are hired-wired to see patterns, and especially faces. On closer examination, and from different angles, a lot of the resemblance of the features on Mars to regular pyramids, or of the "face" to a human face or a lion's face, just disappear. Some of the features of the face were actually due to artefacts in the imaging system!\n\nHere are some other famous examples of pareidolia:\n\nman in the moon\nold man of the mountain NH (collapsed 2003)\nnapoleon's nose rock formation (north of belfast)\n\nThis phenomenon is the basis of  Rorschach inkblot test, even. \n\nIt is hard to imagine that if there had been life on Mars, that they would have left more evidence than that. Also, surely our tests for life on the surface would have produced better evidence.\n\nThis does not mean that it is absolutely impossible that these features are artificial. However, especially given Hoagland's checkered history (see reference), and the lack of evidence, I would say that it is a low probability event. The threshold for belief that these features are artificial is understandably quite high. For outrageous claims, one needs outrageous proof.

If you watch a lunar eclipse, you can see the Moon entering the shadow of the Earth, which is a circle on the sky.  If they could figure out the phases of the Moon and the reason for it, they could figure out that the Earth was round.

The earth is round and its gravitational pull draws us to its center.  Upside-down is really just pointing away from the core...from anywhere.
