I seen on discovery science a computer simulation of the entire universe. The animators used know scientific data to place all the galaxies. The picture showed about a billion galaxies and how they are placed with each other. My question is if at the edge of the universe there are galaxies and lets say in one of those distant galaxies there is intelligent life. If they point their telescopes toward the edge of universe what would they see?

That is unknown, nobody here knows to answer that,you will hear stupid answers and imaginations. Even the scientists don't know.

There are four things you need do first -- (1)forget about any 'edge' or 'boundary' to the universe; (2)forget about unproven theories about multiple universes;(3)try not to think of pre-Big Bang conditions;(4)realize that there's a lot more to the universe than we can ever see.
Now for the really hard stuff to wrap your head around -- astronomers tell us that the universe is 'isotropic,' a fancy word meaning that the universe is the same in all directions, that it has no center, and that no matter where in it you are it looks the same in all directions. What this means is that if some being in a galaxy that's located 13.7-billion light years away points a telescope in any direction he'll see exactly the same universe as we would by pointing a telescope in any direction.

It takes time for light to reach anywhere. We usually are close to things we interact with: other people, bldgs, cars, etc so information light travel time is almost instantaneous. however, any intelligent life on a planet beyond say a million light years away would see light information coming from earth showing an uninhabited planet. (providing of course there was some sort of telescope capable of discerning detail on a planet sized object from that distance) Space and time are connected and related into what is termed: space-time. So, as you look across space, you are looking back in time. Anyone looking at something 15 or so BILLION light years away is seeing it as it was 15 or so billion years ago.
The answer: Anyone looking at earth from the edge of our known universe would see a lump of material newly formed as a planet. They wouldn't see us since we weren't here 15 billion years ago.

according to your question they would see a bright flash of light and then they would see the big bang as you know. they would see like this because the edge of the universe is estimated to be about 15 billion light years away and if the physicists are able to see the edge of the universe then they would see the big bang happening and would also know that they going pretty wrong about the history of the universe. the physicists will watch the big bang happening because according to the big bang theory the big bang occured 15 billion years ago.

Light is a scalar not a vector.. they'd see just as far as light has traveled from the begining of time from their location as we do here.
The'd see pretty much what we see but different..
Your'e a bit flat earthed there.. falling off the edge...... There are other universes out there and we should be able to see them from the edge of ours.

Us. The universe is boundless and self-contained. It doesn't have an "edge." Think of it like the outside surface of a ballon. It can expand (as it blows up) but any point you pick is the same as any other point. You can travel around it endlessly without ever coming to an edge.

I think they would see their reflection...like standing in a room of mirrors.
For all we know, every star and galaxy we see could be an optical illusion? We could be seeing our own galaxy's light being reflected back from different positions and different time periods!

It depends how long they point it that way, if current thinking is correct, keeplooking in any direction for long enough and you will eventually see the back of your own head, should you live that long.

Provided light from earth has reached there, they will see it.
