People say the Universe is "finite." I ask, if it's finite, and if we were to able to fly in to the space and kept going and going and going in one direction, would we come across some sort of a wall since the Universe is "finite"?

if there is anything past the "end" of it, then that is also part of the universe

I am of the opinion that the universe is not finite at all. It is without beginning and without end. There was no "when" when the universe did not exist. If the universe wasn't there, there wouldn't be any time and so there is no point in time when the universe did not exist. All points in time are points in time when the universe is already there. Therefore, it is patently wrong to say that the universe has a beginning in the same sense that every thing in the universe has a beginning. The universe may have started off by a big bang but that wasn't a beginning in the same sense and because we are talking about two different meanings of the word "beginning", it simply does not follow that whatever you conclude based upon one also follows for the other. The universe is everything that is, thus there is nothing outside of the universe.

The word you're looking for is infinite, meaning
the universe has no end.
It's a theory still held by some.
For the most part, it's old hat.
Today's idea's are changing fast. There's a very
strong possibility that the universe is just a large
energy ball that runs a cycle. And, if you could
travel in one direction through space, you would
wind up back here.
What exist outside the universe?
We all have a guess.
My guess is a very powerful undertow which leads
back to a potential center. This undertow could be
connected with the pull exerted by a black hole.
It's really just a collapse of energy.
This is a negative force that counteracts creation
which is a positive force.

String Theory relates to this question quite a bit. Some scientists believe that there are 12 dimensions or more in the universe and that human minds can only comprehend 3 of them right now. Thus, seeing in 3D. This is from wikipedia on this subject:
The basic idea behind all string theories is that the fundamental constituents of reality are strings of extremely small scale (possibly Planck length, about 10-35 m) which vibrate at specific resonant frequencies.[2] Thus, any particle should be thought of as a tiny vibrating object, rather than as a point. This object can vibrate in different modes (just as a guitar string can produce different notes), with every mode appearing as a different particle (electron, photon etc.). Strings can split and combine, which would appear as particles emitting and absorbing other particles, presumably giving rise to the known interactions between particles.
In addition to strings, string theories also include objects of higher dimensions, such as D-branes and NS-branes. Furthermore, all string theories predict the existence of degrees of freedom which are usually described as extra dimensions. String theory is thought to include some 10, 11 or 26 dimensions, depending on the specific theory and on the point of view.
So, basically if this is true. There may be more than one universe scientsis believe. Each one has an end, but through other dimensions others exist.
Just wanted to add that some scientists believe some animals can comprehend more than 3 dimensions, but this is not proven.

people have the choose for a initiating and an end. even with the undeniable fact that the concept of a universe or universes received't be like this. the nature of universes will be that it truly is a non-stop in no way ending procedure with out a initiating or end. a tricky theory, even with the undeniable fact that the project is purely that. If there replaced right into a initiating, then what led to the starting up to initiate, and then what created or led to that, and so on. which will nicely be responded if what we exist in continually existed and continually will exist with out a initiating or an end. It do no longer discuss the universe we stay in ... because what we see observationally exhibits a initiating and finally and end (in spite of everything ability fizzles out as each and every thing spreads out). yet this universe will be easily one of an unlimited type of universes.

It didn't exist at one time and one day it will cease to exist.
Getting rid of a finite universe may not be as difficult as getting rid of yourself and never occurring again1

I can't imagine a finite universe. That's why I really never think of it as a universe, because everything can't really be classified as one thing in my head. I can't really imagine and infinite universe either, but to me it seems more plausible.

some believe that the universe is a closed system, and if you traveled far enough, you would arrive at the point you started from the other direction

I think Callie is right:
= if you traveled far enough, you would arrive at the point you started from the other direction!
