Maybe not the right place for this question, but here it goes!
I've been a big fan of The Atheist Experience for awhile now, and I've heard "A Universe from nothing - By Lawrence Krauss" mentioned several times on the show. I've also seen it a few times while browsing Youtube. I finally had the patience to sit through it in its entirety.
Now, if my understanding of this is correct, isn't possible (regardless of how small of a chance) that when I snap my fingers a universe could explode out my finger tips?
Are there multiple universes contained within ours, or are we a universe inside an other universe, inside another universe etc?
That being said, I find this theory to be sketchy at best. It's front loaded with the bulk of the evidence leading up to it's conclusion and not nearly as much detail about what it actually implies.
