It must end somewhere. But when it ends there must be something on the other side right?

You got a good one there, friend.
As far as I know, we have a pretty good notion that our physical universe as we perceive it all started up between 13-14 billion years ago and has been expanding ever since.
This expansion is mainly due to a beautiful mechanism in which hydrogen atoms pop out of nowhere in space, sucking the energy at hand locally and creating space around them.
Now, if this model proves correct for the times to come, it follows that our universe is finite, although General Relativity has it that we evolve in a Riemannian world which is finite but un-bonded. For short, and without too much accuracy about it, you can visualize yourself as an ant crawling a very large ball. You could then travel the ball as long as you want without an end to your moves, yet staying on a finite surface. Old Albert Einstein thought cleverly to Riemann's geometry and added time as a fourth dimension.
For short, I think you're on the safe side in thinking that the universe is enormous but finite, if it is confirmed along the centuries to come that it had an actual beginning.

When astronomers point their telescopes between two known galaxies, they always find another galaxy. Eventually, our telescopes will be able to detect galaxies that are flying away from us faster than the speed of light, and then they will see nothing. This is called "The Edge of the Observable Universe". If galaxies exist on the other side of this sphere cannot be determined with current technology, but my guess is that there is something there. Another possibility is that the Non-Euclidean Geometry exist where the three angles of a triangle equal less than 180 degrees (maybe 90 degrees), and that the universe folds in on itself. Hey! It could happen!

possibly. WMAP experiments coach that the geometry of the universe (not the universe itself....) is flat. that may factor out that that is countless. besides the indisputable fact that, there's a very small margin of mistakes in those measurements. So that is a chance that the universe is basically extremely, ridiculously, immensely huge extremely than completely "countless". countless gravity? No, for sure there does not be. what's that even meant to point? For one element gravity acts over very lengthy distances. besides the indisputable fact that that is with the help of a procedures the weakest of all the regularly occurring forces. that's outcomes also fall off extremely straight away with distance. countless mild? nicely, no. mild also spreads out over distance. yet there will be no way for mild from stars to have crammed each nook of the universe until eventually stars had existed for eternity. And all of us keep in mind that the universe is basically 13.7ish billion years previous. Plus area is increasing. Over extremely huge distances the cumulative boom provides you as a lot because the point that very distant gadgets are receding from one yet another swifter than the speed of light. So no matter if the mild did shuttle perpetually it may nonetheless under no circumstances attain.

The universe is not infinite, as it started it shall eventually end, how and by what is another question.
Infinite is defined having no limits or boundaries in time or space or extent or magnitude...noone will ever really know.

maybe ,nobody knows yet even we dont know all the parts of our galaxy and its the nearist thing(by the way its abot 17 lightyears wide,now dats pretty big,but mmayb ur right and if we do ever get 2 a wall or something ,and if we break it then if u go in it wll probably juss take us 2 another part in space,but space iz infinate or it could end no1 knows yet untill NASA makes a shuttle or space ship dat can go like 20 times faster than the speed of light(maybe on the other side is heaven!!)

yes it is infinite because we have'nt been able to estimate its size as it is continously expanding. anyway it does have an end and there might be another universe on the other side representing a new dimension. or there can be just the empty space

There are plenty of physics folk who believe in an infinite universe, but finite is more popular.
Think of the earth, it is not infinite but you don't come to the edge of it either; it doesn't "end" in the traditional sense.

There is the universe, then the Kingdome of God. Beyond that, nothing. The universe is expanding constantly, and is infinite to humans, there is no way humans can go beyond the universe.

no, i dont think its got an end. if you are religious then you should know that god created the world in that way for it not to have an end... so if you believe the world ends then to bad for you. i want to believe that must be some more stuff out there. just have faith buddy

Doubtful. If it was, the sky would be ablaze with the light of an infinite number of stars, but it looks pretty black to me.
