Finite? Maybe.
Must have a border? Maybe not. Or it may just be that there is no way to 
perceive it, even if you are almost "touching" it...
You can have an unbounded thing that is finite. A 4 dimention sphere can be 
finite, but it don't have any edge in 3D. And the universe probably contains 
more than 7 dimentions...
