There is no boundary at all!
Because, if somebody says there is a boundary like a spare or like a wall, still you can ask that " what is there over that boundary" ?

As presnt theries tell us unverse is expanading and it does not any boundry at any point of time
But size of unverse keep on changing it is now in expansion phase but in future it may start contracting or continue to expand forever there are four models of universe
1 expanding & contracting
2 For ever expanding
3 after exapanding certain extant unverse may come to platue phase it may maintain that state with out further expansion or contraction
4 universe expansion may be acclerating again this may deaclarate later go for contraction or go on acclerating for ever
these are four models of today but realy no body sure what will happen in future

No. The universe is of finite size, but has no boundaries. The usual analogy is to consider an insect crawling on the surface of a balloon; the bug never encounters an end, but the total space is finite. Now suppose that the balloon is expanding, and you have a fair model of the universe.

our solar system is like a drop of the vast ocean which is universe so u can imagine how big the universe will be. To find the end or the boundary u need to cross the ocean of the universe which is impossible to determine by human beings.

I think the answer to this question is difficult to say. If I say yes there is a boundary and in that boundary all galaxies are there and that boundary is expanding..... then you will araise another question that what is beyond that boundary? Then I have to search for that answer too.... So I would say that there are no boundaries to the space around us.

Scientists can't say that they have seen the whole universe. Discoveries are being made each time. Scientists also find evidence that the universe is expanding, so it's not possible for the universe to have boundaries.

I have to agree with "Blondes_L..." answer and will add our Universe is in the shape of an sphere and is "rotating" on its axis. What lays "outside" the boundary of our spinning Universal sphere, is beyond my comprehension and understanding of scientific thought !

I think there is a imaginary border in a distance of14 billion light years.
Behind this border is nothing* and inside this big circle of 28 billion LY's is all what we know and all of this that will be discovered.
* I mean nothing - no atoms no quarks!

No. There is no such boundary has been found till today. Some years later scientists may find such boundary which may be too much far from us.

no never! pulsating theory says its keeping on shrinking for
sometimes and expading sometimes!
we are just thrown as a 'viruscompared to world' in
the vast universe!
