No one really knows -- we don't have the ability to confirm or deny either possibility.
We DO know that it's still growing rapidly.

There was a theory called the steady state theory which proposed that matter was created as the universe expanded(HOYLE). It was found by observation, that it was probably not true, as the density of matter in space diminishes in time.
Space is considered to be finite but expanding. The amount of Matter is considered to be finite and fixed.
Scientists are still unsure as to the exact amount of matter in the universe: it is this amount that will determine whether the universe keeps on expanding, until we get a dark, dead state, or whether at some future point it will start collapsing back into a singularity and then expanding out again.
I am not sure what you mean by everything has another side. Are you referring to the "outside"? We don't even understand the "inside" of the universe. We do not even have any information about anything not in the universe. The "outside" does not exist in any way meaningful to us.

Perhaps the answer is not in the smallest thing that we can see but in something so large that we can't imagine it.
First there was infinitely nothing. The universe filled it so it must be infinite.
Our technology is still very limited. There may be many other expanding groups of planets, stars, and galaxies a trillion light years away. The number of planets, stars, and galaxies may be finite but much larger than we imagine.
Why do we assume that the universe began with the appearance of what we call the universe? Perhaps what we call our universe was created by the explosion of a massive single star which was a part of a universe where the stars were 100s of billions of light years apart as opposed to the 10s of billions of light years of star separation in our universe. We would not know and currently have no way of knowing. We know the process but, why do we assume that the process started with us when we can only see 15 billion light years and know that even our universe is bigger than that?
The universe's ability to create planets, stars, and galaxies is infinitely ongoing.

There are currently two predominant theories in the Physics arena regarding that question. Of course, each is diametricallhy opposed to the other.
The first posits that since the Big Bang the Universe has been expanding, but that at some point the energy of the Big Bang will be expended, and the gravity of the mass in the universe will cause it [the universe] to begin to contract, until it once again reaches the state of the monoblock and the cycle begins again.
The second posits that atronomical measurements of the universe have proven that there is not enough mass in the universe to trigger the contraction phase of the cycle. This theory refers to "missing matter", or the mass their calculations fail to account for.
Both theories have good points and bad. The bottom line is, we'll just have to wait and see.

Some say the universe is infinite - a nice choice, since infinity can never be proven
Some say the universe is finite where - but until we get there, there's no way to be sure
My father is in the 1st category. When he asked me if the universe was infinite, and I answered truthfully that I don't know, he came with another question: "Suppose it's finite, what's beyond it???" - Same answer actually: "I don't know."
If I knew, I'd also know it was finite, wouldn't I? But I don't, and I'm not afraid to say so.

There are two possibilies how the universe ends:
ONE: If there are plenty of Hydrogen and Helium, the universe will keep on expanding and expanding..... and it goes on....
TWO: If there is NOT ENOUGH Hydrogen and Helium, the universe will collapse upon its own gravity. This is the ending I feared the most - THE BIG CRUNCH.

I believe there is an end.
It ended by people themselves if people continue to ruin it gradually.
Science never stops from their trials and errors of discoveries here and through out the universe.

The universe cannot end.
What we usually call the universe is actually the visible universe. It is a tiny portion of the infinite universe.

i believe it is a principle beyond the limitations of human imagination.. i think in many years to come we will understand but right now we justy havent got a clue, or a chance of having a clue until we learn more about the basic things

There is an end only to the human's ability of imagination, because mankind cannot imagine something to be infinite ... Mankind doesn't comprehend that.
