the farthest end is where it all began according to the big bang theory. the beginning. universe is so large, light actually need years and years to reach us. what we are seeing now in the sky is actually the past, ie what happened some time ago. the moon we are seeing is what the moon was some 5min ago. so if the moon suddenly exploded, we will only see it 5 min later.
IF what we are seeing in the universe is the past, by the same token, then the farthest end of universe is when it all began. where the universe is just one single dense mass (called singularity) some 13billion years ago. that is provided the big bang theory is correct. no stars no moon no planet, just one mass.
unfortunately we have yet the capability to look that far back in time to prove the theory correct. we now need to look at "one point in the past" where all else havent exist yet. that is the farthest end of the universe.

An important open question of cosmology is the shape of the universe. Mathematically, which 3-manifold represents best the spatial part of the universe? Firstly, whether the universe is spatially flat, i.e. whether the rules of Euclidean geometry are valid on the largest scales, is unknown. Currently, most cosmologists believe that the observable universe is very nearly spatially flat, with local wrinkles where massive objects distort spacetime, just as the surface of a lake is nearly flat. This opinion was strengthened by the latest data from WMAP, looking at "acoustic oscillations" in the cosmic microwave background radiation temperature variations. Secondly, whether the universe is multiply connected, is unknown. The universe has no spatial boundary according to the standard Big Bang model, but nevertheless may be spatially finite (compact). This can be understood using a two-dimensional analogy: the surface of a sphere has no edge, but nonetheless has a finite area. It is a two-dimensional surface with constant curvature in a third dimension. The 3-sphere is a three-dimensional equivalent in which all three dimensions are constantly curved in a fourth. If the universe is indeed spatially finite, as described, then traveling in a "straight" line, in any given direction, would theoretically cause one to eventually arrive back at the starting point. Strictly speaking, we should call the stars and galaxies "views" of stars and galaxies, since it is possible that the universe is multiply-connected and sufficiently small (and of an appropriate, perhaps complex, shape) that we can see once or several times around it in various, and perhaps all, directions. (Think of a house of mirrors.) If so, the actual number of physically distinct stars and galaxies would be smaller than currently accounted. Although this possibility has not been ruled out, the results of the latest cosmic microwave background research make this appear very unlikely

There is a very credible theory by Stephen Hawking that the universe is shaped similar to a donut, so that eventually you would be right back where you started from if you were to start a trip at a given point and continue in a straight line (of course this would take millions of years). There is also a theory that it is shaped like a "double donut" (basically a 3 dimensional figure 8), but your trip would still yield the same result although it would take longer. The "edges " of the donut (or donuts) are continually expanding at a phenomenal rate, so it would not be possible to get to the farthest end of the universe anyway.

The BIG BANG is a rediculous joke.
The physical universe in which we reside (there are countless multi-verses besides our own) does have an "end" - i.e., it runs out of "matter" as we know it.
My theory is the Universe precipitated out of a super-saturated quantum soup that was struck by an energy wave created when two "membranes" collided on the 11th dimension - "M-Theory".
When that wave ran out of energy eventually (like waves created by dropping a pebble in a pond), matter stopped precipitating out of the quantum soup and the phycical universe "ends", or sort of peters out. After that there is just the quantum soup which is not matter as we know it, so would just appear to be empty space.
So no, the Universe doesn't have a "edge" with a sign that says "Road Closed For Construction". It just becomes empty (visually at least) space.
The Universe seems quite immense to us only because we are very small. If a human were an atom living in a blade of grass in your back yard, we would all be wondering if our blade of grass was without end - that only God himself knows where the blade of grass begins or ends.
On a Universal scale, we humans are MUCH smaller than an atom would be to a blade of grass. And our Universe would seem like an atom compared to the vastness of the Multi-verse.
To really confuse you, on the quantum level, there may not be such a thing as size or distance at all. A quantum particle "here" can become "entangled" with another quantum particle a million light years from here as if they are actually touching.
To confirm what Yoda said, SIZE MATTERS NOT.

I wouldn't know about the farthest end, and if it even exist, because the universe is supposed to be endless. But the Noticeable space (visible space) with all parts of place, that influenced on us since big bang is in any case final. Edge of light horizon of Space is remote about 13,7 billion light years. That same distance is momentary larger, because the Universe is constantly expanding. So you would have to add some 50 million light years.

One end of it is the farthest to the other . space having no direction , no direction can be mentioned except with reference to some frame or some otehr object in the space and that to with refeence to the movement of sun in relation to the earth if any direction is to be mentioned in relation tpo any celestial body.the space has no direction and ther is no way any direction can be mentioned in the pace purely with reference to any body in space itself .There are quite a good lot of impossibilities and eternal impossiblities in the universe and space .

like in ancient time no one knows that the end of earth
today we don't know the end of the univese
we will come to know in some years about that
till that time we can assumu it has ends at infinity
NOTE:- I think UNIVERSE is an illussion. It shows to us the image of ourselves. But we are not aware of that
