Hello Rallem,
I believe worm holes can be created. Maybe, they don't exist in nature without an external power source, and may I reinerate I am speaking from limited knowledge that may not be worth the time to read, but everyone has opinions. Again, I think the true nature or makeup of "space" is the defining factor in this discussion.
Like I said earlier, this is a very complicated subject. I had never heard it explained as the way this author explained it. I am assuming this is 1 theory on the table. As for "other universes", I was under the impression they exhisted but in another dimension completely void of our own. This is a relatively new subject and perhaps the "language" or words used in explaining are not making it clear.
You know, it could be that the universe needs no end, perhap it is irrelivant for an end. Something else to think about. I am sure one day the great minds will have an answer for all of us.
keep on thinking,
