Okay heres my two cents...
Scientists currently have three main theories on the shape of the universe which will ultimately determine if there is an "end" to it.
It some wierd variable thingo (i forgot its name ) is <1 then the universe is closed something like a sphere. In this case the universe is finite.
If the variable = 1 the universe is flat... in this case the is no end to the universe instead you loopback or something i forget.
If the variable > 1 the universe is in this wierd camel hump shape... if you can imagine multiple camel humps joined together something like that. In this case the universe also has no "end"

I am not a theoretical physicist or anything so i am probably wrong or said something wrong here... but that's all i could remember.

edit: just remembered another thing.... to test this theory scientists want to measure the angles of a triangle. Heres an experiment you can try yourself.
Draw a triangle on a piece of paper (flat universe) suprise suprise 180 degrees
Draw a triangle on a sphere (finite/closed universe) more than 180 degress wow...
I think in the case of the wierd one angle is less than 180 degrees but i can't remember the exact reason why...

Now for those of you who are curious it isn't easy for scientists to measure the angles of the triangle for one simple reason. Get the sphere out again and draw the smallest possible triangle you can. That triangle is probably representative of the milky way in the whole universe. Now if you measure the angle its pretty close to 180 degrees. So scientists need a really big triangle to work out which case is true.

Also another side note if the universe is spherical... parallel lines do cross!!!! Imagine a globe... and now imagine to lines of latitude. These lines are "parallel" however, they meet at the poles...

All this stuff is interesting... but it also confuses the heck out of you
