Suck the air out of a plastic bottle , it collapses under the vac pressure . Thats what I mean by vac pressure
That's not "vac" pressure, that's just the external air pressure crushing the bottle because it isn't balanced by the internal pressure of the bottle.
Your oceans and Islands are all within the set volume , you are looking from within the volume raather than an external view of the volume with all due respect .
If you are within the Universe (which you are), then you are "looking from within the volume" just as a person on an island would be "looking from within the volume" of the ocean. The analogy is still perfectly apt.
If you removed the islands and oceans from the set...
...then you would no longer be talking about an appropriate analogy, so it's irrelevant.
I'm hung up on this because I think science should be precise in explanation with no room or doubt for critism .
You're not arguing the explanation (a vacuum isn't an explanation, it's a concept), you're arguing the definition. A sufficient explanation of the definition has been given in this thread.
After getting banned from Scienceforums.net for denying the expansion of space based on bad arguments, you've decided to come back here and cause trouble for us again?
