I suppose that depends wheither you believe in Einsteins theory that deals with expanding space/universe. (ie: space expands constantly)

There is a book called "Please explain" by Isaac Asimov, which is a
collection of columns answering questions sent in by readers,
originally published in the magazine "Science Digest". One of the
questions that Asimov answers is, basically, yours.

Asimov answers that they stuff beyond the universe is so incredibly
different from what we have here, that we cannot even begin to
consider it. He uses the example of an ant, which lives in the desert
where it has never rained. The ant can walk a long way, and has a
large magnifying glass, which it holds up and enables it to see for
miles. But all the ant can see is sand.

The ant cannot begin to imagine that there is stuff called "water" or
what it is like. We are in the same situation as the ant, when it
comes to the universe. Asimov's answer is that the only thing that we
know to be beyond the universe is "non-universe".

Whilst this isn't much of an answer, it is the best that we can do.
Whatever is beyond the universe is very different indeed from what we
have here. Space and time are uniquely tied together, and will not
exist in the same way outside the universe.

Physicists are arguing about the fundamental nature of matter, and
they don't agree with one another. There are theories that propose
different numbers of dimensions of space, and different relationships
between space and time.

Too many answers but nobody said what it is. First one has to establish what is space. Is Space means what we see in the sky? The questioner seems to ask if there is no material after some distance, what next?
The theory of relativity says that light bends or deviates due to gravitational force. To prove this theory, location of a star close to Sun was measured on a total solar eclipse day. It was found to be at a different angle than measured in the night sky. This indicated that light bends due to the gravitational force. So, it is thus estimated that the light bends inwards due to the gravitational pull of massive bodies. In this way light has to complete a closed loop. Some say the universe is in donut shape. Hence there is no way to think beyond this, because where there is no light (units of light speed is distance and time) there is no distance (space) and time. It is also believed that universe is expanding. This means the volume of universe is increasing. It means light is traveling for longer length covering more area.
So space exists as far as light travels. Beyond that no time, no space, no material / energy (E is related to mass and light speed).

If you were on a galaxy at the very edge of what we can see from Earth (due to the expansion of the universe some far-away galaxies are receding at the speed of light and we cannot detect those) then you would see a universe much the same as what we see from here (not in detail, but overall). To you, in that far away galaxy, the Milky Way (if you could see it at all) would be receding from you at or very near the speed of light, too.

In other words the "Edge of the Universe" is really all points appearing to recede from us at the speed of light, not a physical edge. So, the answer is thought to be more space.

Now, if the Big Bang theory is correct there has to be a center of the Universe. That center has not been found so far, because matter seems to be expanding outwards at the same velocity (which increases with distance) in all directions (don't even think WE are the exact center..that would be quite unlikely and egocentric).

Astronomers believe the Universe is about 15 billion years old, but that figure implies that the edge of the observable universe (about 15 billion light years away) is the real edge. So far there is no evidence that it is--we just can't see past it. There are, however, other pieces of evidence to support a figure like 15 billion years (rates of stellar fusion versus mass, and so forth).

Now you are getting into really interesting territory.
You are suggesting that space has perimeters and if you are right what lies beyond the periment is the exact opposite of
space.I wish your question was about the universe because you
by asking this question are leading me to ask if space is sharing a boundary with something else what is happening at the edge of space..I can only answer that what lies beyond space is the force that makes it.

Here is a photograph that we have recently taken of the beginning of the Universe. Astrophysicists think that this Universe is a quantum singularity, sorta an aberration or novelty. But, whatever all that energy is that first appeared as shown in this image, it is expanding out forever, per recent findings. What it is expanding out in to, we cannot yet comprehend because all that we CAN comprehend . . . energy, matter (tangled energy), and the spacetime fabric which IS the expanding Universe itself, is made of all that original burst of light as seen in this image. What I find fascinating about this image and which is probably incorrect but thrilling to me nonetheless, is the notion that by looking into those blobs of light, perhaps we are glimpsing into whatever is beyond or before this Universe.

more space, you might ask yourself well whats behind the more space, well you got it more space, in between space is galaxies, we live inside the milky way galaxy, our sun is but one of the 400 billion stars in the milky way galaxy. There are trillions and trillions of galaxies, with hundreds of billions stars in each galaxy. Scientists believe our universe is about 14 billion light years across. A light year is 5 trillion miles in distance. So our universe is 5 trillion X 14 billion = 70,000,000,000,000,000,000,000 miles across. Which means it would take light from one end of the universe 14 billion years to travel across to the other end of the universe. The speed of light is the fastest traveling thing in the universe, 186,000 miles per SECOND. So the light from our sun, takes 8 minutes to reach us. the sun is 93 million miles away. Its all pretty simple, just a lot of numbers, memorize these numbers and wow your friends, spread the word of astronomy, it is our greastes gift of knowledge. Who cares about Anna Nicole Smith when you can debate the universe. Hell we all might become gods if we start using our brains.

No one knows actually. The space itself is so vast and moreover Edwin Hubble stated that the universe is ever expanding. According to religious books, we can only state till today that beyond space, there is only hell & heaven.

Beyond space their is darkness filled with vacuum.

Beyond space there is another world where god lives with our ancestors.

When we reach the edge of the universe there is a big sign there and written on the sign are the words:
STOP HERE YOU CAN GO NO FURTHER
