So the universe is like raisin bread. I just knew I tasted it from somewhere before but couldn't place it.

I feel that while worm holes and black holes are both cosmic singularities I don't think they have anything else in common, but I am not at all certain that there is a worm hole and think it may just be a plot device to a science fiction show because I have seen no hard evidence of the later. If worm holes are real thogh, I wonder if there is any connection to black holes and if so what?

I wonder if that article is the writings of a hypothesis or if this is is an actual theory because the author seems very sure about his answer, but I wonder how he can be if other scientists still discuss the possibilities of other universes outside our own.
