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. A picture like this
----------------------------------- <-- Universe One
----------------------------------- <-- Universe Two
doesn't mean that they are flat, it just means that they are 3-d universes (like ours) separated by another dimension. _______________________ When scientists say that the universe is flat, they aren't talking about ordinary 3D spacial relationships as we would intuitively expect. The nature and 'shape' of space is a very complex matter. Think about the surface of the globe. There is only so much area on the globe, and no more. But if you could travel freely in any direction for as long as you wanted, you would never run into a barrier you couldn't crnoss, assuming you can make it over every mountain. This means that the surface of the earth is finite (there is a limit to the area) and unbounded (nothing prevents you from moving freely in any direction even though the area is finite). Models and theories of space have more to do with complex mathematics than with space as we experience it on a moment to moment basis. Theorists consider that space itself might be similar to a globe in that there might be a fixed amount of space, even though you could travel for ever in a straight line and never come to a barrier you can't pass. In other words, some have considered that space may be finite and unbounded, like the globe above. This would mean that some fascinating curves and convolutions might exist in the very make-up of space itself. These features couldn't be observed very well by any individuals, but they may be seen indirectly through relativistic affects and observations. The current understanding is that space is 'flat', meaning that it is not finite and unbounded. It appears that our 'flat' space is expanding indefinitely far in every direction, forever. So counter-intuitively, 'flat' really means 'fat'.
The Universe is not flat, the Total Energy is W = -mGM/r + cP. The Curvature of the Energy at the Boundary is -XX*W = -(d2/dr2 + DEL2)[-mGM/r + cP].
The radiant energy (v=c) maybe flat but the matter energy mGM/r is not flat.
In general the Universe is not flat, it is finite and closed.
The universe isn't flat. It is 3-Dimensional time and space. Galaxies are depicted as being donut shaped and flat
The inflation theory explains why your universe is structured and uniform and suggests that the universe is flat in shape. The universe is believed to continuously be expanding since the Big Bang.
That means that, on the largest scales, the curvature of the Universe is insignificant. As far as I am aware, it has not been established whether - on the largest scales - the Universe is perfectly flat, but current observations do seem to confirm that it is quite flat, as far as we can see.
There are three models for the possible shape of the universe, one is spherical. The three concepts provide for a spherical universe, a hyperbolic universe, or a flat universe
That the world was flat
In the 3 dimensions the human mind can comprehend directly, no. But in the forth dimension, space and time, understood by astrophysicists and cosmologists, the universe is flat in every direction.
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.
It's flat. It is the center of the Universe.
The lowest note in the universe is a b-flat 57 octaves below middle c.
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.
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.

they belive that the earth was flat.
Sphere, Hyperbola and Flat.
1. The universe continues to keep expanding 2.The universe slowly stops expanding 3.The universe will stop expanding and collapse into itself H.g.g
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.
that the earth was the center of the universe and that the earth wAS FLAT
it can only in a alternet universe were i can fly
Open or flat. See related question
In simple terms it is the shape of the universe. Many theories have been put forward for the shape of the universe, but it is generally thought of as being flat, or very slightly curved, but not so curved that it would fold back on itself to form a sphere, cylinder or torus (doughnut shape). This concept of being "flat" requires some unusual thinking because the universe is clearly three dimensional (with a fourth dimension of time) and not a flat two dimensional surface.
Correct. In ancient times people believed the Earth was the center of the universe. (They also believed the Earth was flat.)
The earth is tilted at 23.5 degrees! It's flat and the center of the universe
The exact shape of the Universe on a large scale is not known yet. As far as we can see (roughly, the "observable Universe"), the Universe seems to be fairly flat, meaning that if it does curve back on itself like a hyper-sphere, or some other shape, the entire Universe is much, much bigger than the part that we can see.
yes, early navigators drew a map that was flat and so people though the world was flat but then we had a astronaut go up in space and he found out that our planet is a sphere!!!!!!!!!!!!!!!
