I have the same problem grasping how negative gravitational energy and quantum fluctuations can lead to spontaneous creation. I read Krause's, A Universe from Nothing which goes into more detail on the issue but I still don't understand it. If you ever read anything that clears up your confusion be sure to post here.I got the Stephen Hawking's latest book from the library for my Kindle Fire: The Grand Design: Stephen Hawking, Leonard Mlodinow: Amazon.com: Kindle Store
It's a pretty interesting book but a little puzzling...
Regarding questions, towards the end there was this for example:
On the scale of the entire universe, the positive energy of the matter can be balanced by the negative gravitational energy, and so there is no restriction on the creation of whole universes. Because there is a law like gravity, the universe can and will create itself from nothing in the manner described in Chapter 6. Spontaneous creation is the reason there is something rather then nothing, why the universe exists, why we exist.
Well it's back to Chapters 5 and 6 for a review.
I guess it goes back to Feyman's quote: "I think I can safely say nobody understands quantum mechanics." I haven't met nobody yet but I plan on asking him about spontaneous universes when I do.
