Thanks for your efforts Teuton, but I think I've resolved the quandary over terms - as Krauss says this is a moving of the goalposts moment - I was hoping for a more technical explanation of what the quantum fluctuations in an absolute-vacuum might consist in. For example, they are obviously subject to the laws of physics but how do they relate to the laws of physics; are they responsible for the laws by which they operate, in some way? As I said, my paucity of understanding of this area is something I want to get a bit of a handle on - which is why I posted it here and not in the Philosophy section.
