Midnight thoughts

universe?

Have you ever wondered, what beyond the universe is?

I mean, the universe could be like never ending, but just imagine that, there must be anything "around" the universe.

Is there just black and nothing else?
Doesn't it has to have an end?
But how would that end look like?
What is beyond the end?

I don't know but I'm lying here in my bed and I don't find a solution.
