If the Universe is infinite then it has no shape. If the Universe is part of some theoretical 'muntiverse' then it is probably sperical, with us in the center (haha).
I think no definite shape, but to imagine it as an ever expanding body, makes me a bit uneasy. We like to relate things to the bank of pictures and possibilities we have, and to wonder what lies beyond the last edge of the universe is , so so numbing.
The universe goes on forever and if it didn't - there would have to be something on the other side. So I am thinking it has no shape, it just goes on and on forever with no end. That is a hard concept for my brain to wrap around - much like our national debt--figures so high, I cannot fully take it in.
I imagine it as a huge semi-circular web that is part of a backdrop of other universes. I tend to side with the M-Theory people...because super-stretchy membranes are just neat. Either that or its all sitting on a turtle's back...and it's turtles all the way down.
For those who claim that the Universe, which is a concept, has 'shape'; they need to check themselves into an insane asylum.
Space has no shape or borders. Only matter does.
The circle or a-symetrical,based on outward energy force caused by the Naked Singularity(big bang) and by detected microwave background radition on Nasa's I-rad. Taken into consideration Dark Matter,However now it has recently been discovered that a phenomina called DARK FLOW throw's all theroy for a loop as it consentrates to a single point of focus near the edge. Geodessics within a 4 dimentional space time curveture from a metric tensor as equaded in pythagoris therom show that parelell's don't remain constant.
Indicating outward expansion. However if using elucidian geomerty and not hyperbolic geomerty when solving field equasions for general realitivy,the metric tensor will be true. And if using Hyperbolic Geomerty the metric tensor is true but DARK FLOW says other wise1Therfore I would be inclined to go with AN A-SYMETRICAL SHAPE!
For this dimention! And inter dimentionaly stacked on top of each other!
Let's look at the stars, planets and solar system. What is the one geometric design that's constant? The circle.
I believe that the universe is round, just like everything else. It's not expanding, we are simply turning so that we "see" more of it as time passes. That's my take on the universe.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
