is the universe round?

the universe is a giant monkey.  We are just a part of a galaxy which is a little blood cell inside the monkey.

I don't think any knowledgeable person claims space is infinite.  In fact, the knowledgeable people admit they have no real clue how space is shaped or where/if it ends. [See source.]\n\nI've heard it said that Einstein once said that the only thing that puzzled him more than an infinite space was a finite space.  Astrophysicists are still puzzling over this issue.\n\nAt this moment, astrophysicists are just beginning to come to grips on the shape of our observable space (our known universe).  Based on the value of a cosmological constant, three possibilities have emerged: spherical, flat, and saddle shaped.  \n\nThe flat universe (like a big pancake) has the most proponents nowadays.  But it wasn't that long ago that spherical (like a balloon) was the shape celebre.  There is no "proof" for any of these shapes; just fancy mathematics, so the astrophysicists are busy looking for the proof of one or the other.\n\nWhen talking about infinite space and such, we need to differentiate between space and our known universe.  Space is the void into which our known universe was born via the big bang.  Our known universe is a bit over 13 billion years old and we have been able to see out to just short of that distance.  So we are almost to the edge of our known universe with our observations.  What lies beyond that, though, is still a complete enigma.

I believe the universe is a 'closed' shape, meaning that there is no 'edge', however it does have a finite size.  But just to entertain your question, if we one day did reach the End of the Universe we literally would be unable to describe anything on the otherside.  Everything we know about physics, space time, the fundamental forces, the universal constants and so on only exist in this universe.  Anything 'outside' of the universe could potentially then have different laws of physics and thus would be completely beyond our comprehension.  Words would literally fail.

No I think that the alignment of the universe can answer and solve many questions and problems ,Great mathematicians have done this for Centuries and you would be amazed at there predictions and preciseness

The earth is round. There are some physical proofs below, assuming you don't trust the pictures of the Earth taken from the various space programs.

the radius of the observable universe is about 46 billion lightyears.  currently, the expansion of the universe is accelerating not decelerating.  any observers existing in the very distant future will only be able to see bodies within the galaxy that is the result of the merger of the milky way and andromeda.\n\nmaybe these sites will help.\nhttp://map.gsfc.nasa.gov/m_uni.html\nhttp://www.astro.ucla.edu/~wright/cosmo_01.htm\nhttp://universeadventure.org/\nhttp://www-supernova.lbl.gov/\n\ni have something else for you to think about.  the universe is 13.7 billion years old yet has a radius of 46 billion lightyears.

Universe is not exactly rotating or spinning... it is said to be constantly expanding... and sorry i don't know about the big band

Actually, they know it isn't infinite.\n\n\nThe findings are mostly thanks to hubbles big idea and discovery, but they can now confirm that indeed the visible universe is finite thanks to WMAP.\n\n\n\nAs for the possiblity of space outside of the visible universe...we have no idea.

The reason the world is round is pretty a more than imaginary question and you could keep asking that question forever and ever without getting the right answer.God is the supreme being, the most powerful and he just created the world the way he liked.If it were you that had so much power,won't you do anything you want with anything you desire?\nLike I said there would be lots of answers to this question scientifically,geographically and mentally but the main point is that God is the all powerful.

Planets came from clouds of spinning gases that later solidified.   So they are pretty round, but not exactly spherical.  The earth is around 8,000 miles in diameter.  Black holes are proven.  They were proven using gravity experiments on nearby bodies and light experiments from stars "behind" them when viewed from earth.

the theory is not correct so it will not happen, the truth is that the universe is flat, but curled up at the edges, I saw it through my telescope last night

first: by world, do you mean earth? \nIf so, think about all things spinning, are they not always more or less round or oval shaped? Actually so is the earth. \nOn the other way,I think that by spinning, a lot of things get that shape. Especially as like the stars and planets, they tend not to be in a fully finish state. Ok, that is my answer but I am no astronom only a nurse... MC

Many  astronomers think that the Universe is infinite. See, this\nwebsite for the complete explanations.

The Universe stretches out like a tent.Note a tent has rims.that means there is a limit to the strech.\nA tent curves at the rim . The curvature of the Universe is based on the area and the volume its containment has.\nA very long shot calculation would be 2.112676056/10^26\nThe overall gravity power stored in the volume of the Universe would be proportional to this curvature.\nNote The observation of Hubell based on the doppler red shif is not a conclusive proof of the expansion.\nThe wave dispersion effect  is just as valid an  assumption ,and it disproves Hubble's Redshift. Therefore I would be skeptical about those who believe that the Universe is expanding. The initial cosmological Constant of Einstein may have been the correct assumption.For all those who feel they know the answer saying they have proof should not talk out of the top of their hat!\nAs far as I am concerned it can be  postulated  that in order for  the Universe to function as it does , it must maintain rotational equilibriun.\nAnd on that note ,its constrol system can always be expressed as a second order differential equation no matter how many variable are involved and it will  maintain a steady state equilibrium.This would involved system that gain mas and sytem that loose mass.Rotational equilibrium is maintained by the revolving mass increasing its radius or decreasing it. It Has nothing to do will the Universe changing it radius.Nor is the Universe a ballon that is being blown until it explodes.\n\nI wonder how Stephen Hawkins would view this explanation.?

They really don't. Galaxies come in all sorts of shapes and sizes, spiral, elliptical, round, etc. Few are rotating though, and some in different directions. All seem to be moving away from each other, though, as most scientists agree that the Universe is still expanding,thus blowing a few holes in the old "big bang" theories.

not without knowing it is right to a reasonable degree. For instance if this were 1400 and you asked if the world was flat i would say of course but we now know that it is round. Science is constantly changing thier answers to a lot of questions due to the fact that new research is proving them incorrect.

The universe is said to be expanding,at least in the sense\nthat all of the galaxies are supposed to be drifting farther\naway from each other.That would seem to contradict your notion of a tremendously big circle as there's no gravitational pull binding them together.\n Also,if space is finite...then what's outside the boundaries?
