A Universe from Nothing

So, particle physicists and cosmologists are theorizing that there are infinitesimal universes popping into and out of existence all the time and that these universes are occurring from nothing: no space, no particles, no gravitational fields, no electro-magnetism, no laws of nature: nada, zero. These universes, they theorize, are the result of quantum fluctuations of ‘virtual particles’ (here one nano-second, gone the next). And, the thinking goes, there is a very strong likelihood that the universe within which we live may very well be an inflated version of such a universe from nothing.

I must admit this is all pretty hard for me to grasp, has me wondering about what nothing is and isn’t, among other things. Does this mean, our universe having popped into existence, that it could suddenly pop out of existence as well? If it did would the resulting vacuum suck all and everything into a very large black hole only to reconfigure as a new universe: a mirror image of its former self?

I find these ideas pretty exciting and they have me wondering about what the quantum world will show us next. I imagine, though, theologians might not like the ideas very much.
