Craig, thank you for explaining all of that, and a special thank you for the lovely comment at the bottom of the post.
Brian Greene is a favourite of mine and he does explains things so incredibly well. In fact, this afternoon I have just downloaded his latest NOVA series, "Fabric of the Cosmos". Here are the episodes if anyone is interested...
Quantum Leap
The Illusion of Time
What is Space
Apologies if I have deviated from thread a wee bit, but in order to help understand what's going on today in physics, these documentaries are helpful.
