It's like saying tossing a fair coin 100 times and coming up heads means the 101st toss that comes up tails isn't truly tails because the first 100 were heads.
It is nothing like that. The observations are not random, independent events. You can not apply such statistics to the balloon case.
but isnt "No Boundary" the samething as infinite or eternal? How does changing names and terms assist that which is already an accepted idea in the first place.
No, it doesn't mean infinite or eternal. The two dimensional surface of the earth has no boundary but is not infinite in extent.
