If space is a vacuum and not a fabric made out of a material how do wormholes work? (Please avoid the pen through paper analogy)

Question

I’m struggling to understand how someone can create a hole in space if space is already a vacuum. I mean, you can’t create a hole in emptiness. So where does that leave wormholes?

Answer 1

Well, space isn’t a fully vacuum.

But you need to forget that space is only 3 dimensions. Only then it makes sense.
