Empty space is like a quantitative field in a fixed length record which contains a zero. Void would be if the field did not exist at all.
The thing to remember is that space/time is created as the universe expands. It doesn't pre-exist. Space/time doesn't expand "into" anything.
The condition which exists before the beginning of space/time (regardless of cosmology) is the void.
Alrighty then, now stop that.. Empty space is WHAT?..
An empty jar on earth has air in it..
What does that empty jar in space with the lid on, have in it?..
If you say nothing.. How can that be..? How can there be nothin?..
Maybe I'm having trouble concieveing of nothing..
nothing would still to be something.. d;-S
