do u know any site with picture of universe?
i haven't found any good even rough map of universe

the universe is four-dimensional, and we have no words for four-dimensional objects, but if you can imagine a two-dimensional version then it seems to be something like the surface of a sphere. it is this surface that is expanding. the universe is finite in size yet has no center and no edge.
380 000 years after the big bang, the universe had cooled enough for electrons to combine with atomic nuclei and form atoms (about 76 percent hydrogen and 24 percent helium). at this time, the universe became transparent because the electrons could no longer scatter light. we see this light today stretched to microwave wavelengths and call it the cosmic microwave background. the universe was much smaller then, but we see the cosmic microwave background in every direction we look.
the universe is 13 700 000 000 years old, but observations by nasa's microwave anisotropy probe seem to show that the cosmic microwave background is at least 46 000 000 000 light-years away.
look here, really:

Hi. The VISIBLE universe is close to spherical. The dough and raisin analogy is hard for most folks to visualize even though it seems pretty accurate. It's not a matter of belief, Its a manner of explanation.

No the universe is currently thought to be a saddle - a bit like a pringle. We don't see this because it only appears to be curved over enormous distances

isn't this based on the big bang theory? that boom - everything spread out and it's slowly coming back together.
i think it's bs, cause not even the Hubble can find the end of the universe. they did a deep zoom, finding the darkest spot in the sky, zoom in, finding the darkest spot out of that patch, zoom in, etc, etc, and all they found was more and more galaxies.
then a couple of years ago, they were measuring the gravitational effects two galaies were having on one another as they were passing each other. the results were the two galaxies had little effect on each other and it completely threw part of the big bang theory out, cause everything isn't pulling towards each other and in 500 billion years all mater isn't going to collapse back in on itself

It is impossible to draw the shape of the univese because it is in 4 dimensions. It is nearly impossible to think it let alone draw it. Our brains are not able to comprehend it.
It doesn't have a shape.

No, no one has seen the infinite extent of it. Science can only assume based on current knowledge.

Check with AAA. They may have a map.

Like all science it is only a theory, until we see for ourselves if it is true or not!
