If the earth was flat then it would be impossible for our earth to have seasons, because on half of the year we would have complete sunlight, the other half of the year we would have complete darkness. Also the North Pole would probably be the place with most volcanic activity, which it isn't. So that shows you somethings about what happens if the earth is flat. (and no, the earth is not flat or else all of the above would happen.)
It isn't because scientists have showed us pictures of the actual earth and its round
and you can fall off the side of the earth

Is a flat universe 2-dimensional?
Is the universe really flat? The universe has been suggested to be flat by the WMAP satellite data. We've got 5 years worth of readings under out belt. But the jury is still out because of disagreement. If the universe is curved, it is curved so slightly that we cannot tell. A very rough equivalent is that the earth appears flat to the individual walking across the Salt Flats in Utah. The Planck Satellite launches in early 2009, and data from a successful launch may settle the matter to the satisfaction of the majority of investigators. A link can be found below. Why is our universe flat? Scientists are still debating the size and shape of the universe. What we can see is spherical, but other evidence might suggest a wide and flat universe. Though still very thick, the universe might be about the dimensions of a piece of paper. Alternatively, it might be infinite. Be careful when seeing pictures having to do with string theory, multiple universes, etc. They show pictures of flat universes to make the theories easier to understand, since we can't picture more than 3 or 4 dimensions.

Is a borderless universe a reality?
Because any border of the universe it not observable, the reality of it remains a theoretical pursuit; but generally, cosmologists agree that current data would tend to indicate the universe is infinite and "flat". One popular model (FLRW) posits that the universe is without boundaries. Research and mathematical models postulate both a bounded and unbounded universe, and some even purport that the universe might be bounded in some directions (or dimensions) but not in others; often models are speculative and hampered by inherent limits in experimental method. In particular, recent efforts have shown that we might not ever be able to distinguish between a flat, open or closed universe if the cosmological curvature parameter is sufficiently small.
What does the structure of the universe look like?
According to scientists and technology, the structure of the universe seems to be round and flat, so the space can be bent. Another theory would be round and very spacious. Really, no one knows for sure.
What are the three predictions of your Universe?
The "Big Crunch" idea was that the expansion would eventually stop and the universe would collapse. All evidence today says no way. The "Yo-Yo" says the universe repeatedly expand, collpses and then expands again of a roughly 70 billion year cycle. There is no evidence for this. The "Big Rip" says the universe will simply expand forever, with other galaxies gradually getting so far away that they fade in the distance, and then stars burn out and everything gets cold and dark forever.
Would you see the back of your head with an infinite power telescope pointed into space?
This answer could be yes or no, depending on if we are absolutely sure if the universe is flat or a closed (curved) universe, which we are currently not sure of. If the universe is flat, the answer would be no because the universe would be expanding and traveling faster than the speed of light, so you could never see the back of your head. The answer would be yes, if the universe was closed, because it can keep going and get back to where it started like we can walk in straight line on earth and end back where we started. ================================= And don't forget that even if it's closed, you would have to wait several billion years, until the light from the back of your head made the trip around the universe and wound up back where you are now. No matter how 'powerful' your telescope is, it can't reduce the time light needs to travel from one place to another. More 'power' only allows it to detect dimmer light.
What evidence can you cite that the universe is flat How does that compare to previous beliefs about the universe?
The universe isn't flat. It is 3-Dimensional time and space. Galaxies are depicted as being donut shaped and flat
What does the inflationary model predict about the destiny of the universe?
Flat
What happens when the earth is flat?
Nothing in the Universe is as large as the Earth AND flat. If the Earth were flat, it would be the only flat object, other than some small asteroids.

Earth is round so why is the universe flat?
The shape of the Universe on a large scale is not yet known. As far as we can see, it seems flat; for comparison, when you look a few meters around you, the Earth also seems to be flat. On a much larger scale, the Universe may have a positive curvature, a negative curvature, or no curvature at all.The shape of the Universe on a large scale is not yet known.

What are the three current theories on the shape of the universe?
Sphere, Hyperbola and Flat.
How did the earliest astronomers learn what they knew about the universe?
they belive that the earth was flat.
What is an open flat Universe?
This is a theoretical model of the universe. A Friedman Universe can have positive, zero or negative curvature. If the curvature is positive then the universe is closed and curved. A light ray going in any direction would make a complete circuit if the universe and return to the starting point. If the universe has zero or negative curvature it is open and unbounded and said to be flat. A light ray would travel in a 'straight' line and not return to its point of origin.
What did people believe before Copernicus?
that the earth was the center of the universe and that the earth wAS FLAT
Can 2001 Dodge Caravan be flat towed?
it can only in a alternet universe were i can fly
Is the universe flat?
No the universe is not flat.This can be observed simply by looking into space.In every direction from earth there are stars in the sky, for light years away.The redshift also dictates that nearly every galaxy is moving away from us.This could be observed from anywhere in the universe.So the universe is expanding in all directions and is definitely not flat.Comments: Unfortunately it's more complicated than that.When it is said that "the Universe is flat" that doesn't mean the Universe is two dimensional, or anything like that. It is confusing, but the word "flat" is being usedin an unusual way.(Sometimes scientists do use words in a confusing way.)It refers to the amount of mass in the Universe and whether that mass will be able to stop the expansion of the Universe.At present, astronomers are not sure if the Universe is flat or not.Another meaning is that space itself may be "flat" (or "curved").(Strictly speaking it's "spacetime" that may be flat or curved.)So, our "ordinary" three dimensional space may be flat or curved.Even if it's "flat" it's still 3D space.These ideas about the fate of the Universe and the curvature of space are closely connected.So, after all that, the answer is the Universe may be flat, but we are not certain.Note: See "related links" below.The second link is probably too detailed for many people, but it gives a good summary of the problem.Even if you can't understand all thedetails (and I don't either) these links give a good idea of what this question is all about.
