It all depends on your concept of nothing.

I read this thread and i thought to myself.. what is nothing?

Someone mentioned that nothing doesnt exist because we cant see it. That sparked a thought that you cannot see something that doesnt exist. It is very well possible that this nothing is all around us.

Picture this. Your in a empty room with a table. Nothing is on the table. You cant see nothing. The word nothing cant explain what this universe "nothing" is. We would have to use some other word to understand.

If it is true that 'nothing' is at the end of the universe it means that you wont be able to see the end. I think of it as being in an empty room, but nothing being able to see any walls and when you look in any direction you only see your back.
