Without going into many complex theories. Science teaches that the universe is finite, it can only expand so far because there is only so much energy in the universe. Obeying the law that energy can neither be created nor destroyed the universe can only expand to a set size, something we cannot compute, before the energy runs out and it goes through the bid cool down which means everything freezes then shrinks back. The universe is currently still expanding so we have not hit the finite point where the universe will stop expanding and either cool, or stay static for awhile.
Outside of our universe there are most likely more universes
It is hard to go outside the universe one can't just pass through the ends to another universe. As the later poster said it is due to the curvature of space so if you were to get in a space ship and fly straight out from earth you would never pass into another universe you would eventually come back to the starting point. Much like walking around the earth. It is hard to explain alot of it is based on some pretty complex geometry with negative space that takes up space etc.

It's easiest to think of the Universe as infinite. The alternative is that it's curved so that it bends into itself, but that's somewhat difficult to imagine, just like it was once difficult for people to imagine a round Earth.
So there's nothing "outside" the Universe. If it's finite, then it bends into itself and has no edge, just like the Earth has no edge. Imgine discussing the finiteness of the Earth with someone who had never seen Earth on a space foto and had no clue that it could be round. He might ask "but if Earth is finite, what happens when you sail or walk into the edge?".

What in science has taught us that things must have an end?

It has??
Guess I must have slept through that science class.

Yeah, and what's on the other side of the end?
