universe

no one has ever gone out of the universe and have a good perspective of it's shape. I couldn't imagine how a finite mind can comprehend such vastness and greatness. Any definition of shape is erroneous and can not be objectively proven and will only be speculation. The best answer would be what the Jewish proverb says "Teach your tonque to say I don't know"

The universe does not have a shape! If the universe had a shape, it would mean that the universe has an end. Let us suppose that the universe is a sphere. If it is a sphere, it must be bounded by something. Whatever that something is, what is beyond it? If space has an end, there must be more space beyond the end! The answer is that space is endless and therefore has no shape!

Einstein always thought the universe was finite. I think it is eliptical and revolves endlessly. I also think there are many diminsions to it of which we have very little understanding. We know everything is moving and is not static.

So far there has been speculations,as to one or more Universes. To the best of my knowledge,the dhspe is not known,eventhough,the event-horiazon,is well known. http://curious.astro.cornell.edu/question.php?number=62 The above link should help you.

I think That's a question with no answer. Because no one knows the exact answer. So everyone has the different answer with his wishes. In chinese philosophy, the universe should be round. Maybe others think it's other shape. In short, who knows??
