as far as the current theory describes the big bang was a rapidly expanding singularity.
(this was shown by Penrose and Hawking)
They concluded that there must be an infinite ammount of 'material' on the outer which is capable bending radiation from it back on itself.
if you will, this is a sort of border or container
so what's infinite here is the ammount of stuff on the 'wall', which is still rapidly expanding.
this means the universe isn't of infinite size for having a border, but as far as we know we could say its infinite, cause we cannot make it to the border since its expanding too fast to ever reach it

Whether or not the universe is infinite, scientists cannot say with certainty -- only that the boundaries or limits appear to be infinite.
Deep space images have been made of visible, detectable objects whose approximate distance is 13 billion lightyears away. Scientists can say with that certainty, that the universe is that big and that old, at least. But, all readings of "red shifted" spectrophotography tell us that the vast majority of observable objects are receding from us at an ever-increasing speed. So, where observable evidence ends, logic and reason have to take up the "slack" of the unknown.
It would be nice to compartmentalize everything. Neat packages make for an easier time of explaning. But, what lies beyond the universe? Another universe? No one knows because there's no present way to detect the universe's limits and beyond.
In the late 1920's and early 1930's, Edwin Hubble produced "red shift" evidence that developed into the "Big Bang" theory -- a logical projection backwards in time of what might have happened "in the beginning".
Now, 70 - 80 years later, we have several observations of these same objects accelerating away faster now than they were measured originally. So, new theories, "string" and "membrane" have evolved.
Keep in mind that these theories are logical projections from measurements and observations, but they get to sounding like scientific fairy tales. Each new observation may strengthen or weaken a theory's validity. It's the best we can do under the circumstances.

I believe that space is infinate, and that there are any number of galaxies outside of our own. For anyone to think that the Milky Way is the only galaxy is a pretty small view of the universe. I believe that the universe is infinite and does go on forever, scientists just don't know how far it actually goes outside of our own galaxy. It is true that mostly everything is contained in something, but look at Mathematics for example, there are infinite numbers. They will go on forever with no ending.

'Stuff on the wall' is a reference to the dots on a balloon's surface moving away from each other like the galaxies in the universe does. This a poor analogy, the universe is not like a balloon. A better model would be like the raisins in a baking muffin, the raisins are inside the muffin but they move away from each other as the muffin expands. Space is not infinite it is limited to the size of our universe.

For material structure, in order to exist as a structure ,it must have a containment.
Since space structure was created into an architecture ,it has a containment with boundary. Hence it is not infinite.

The Universe exists through consciousness - if no one were here to "observe" it then it wouldn't even be as real as an imaginary Universe in the palm of your hand.
Beyond the edge of this Universe probably lie other Universes (just like there are other galaxies separate from the Milky Way) but beyond all of them - an unimaginably long way away, reality becomes blurred and nothing exists unless someone goes out there to give it existence.
Essentially, you are the creator of the Universe.

Yeah. Space is contained in...never mind. Space is infinite. There is no limit because it just keeps going away.

well i do believe that there is a universe boundary and then there's infinite space.
