Sorry if this adds any confusion Brian, but Carl, if I am on the surface of the balloon ( attached) when it is inflated and look toward the inside, left, right, up and down - yes I see all expanding away from me. However when I look behind me, wouldn't things get closer to me (if the balloon surface was permeable) or move at the same distance (if the surface of the balloon was solid.)?
Or ... when the balloon is inflated do I detach from the surface? cause then I would understand.
Or am I taking the whole balloon thing too literally?
I've seen this explanation ( the balloon one) before and couldn't work it out.
So thank you Brian for posting this and I hope to understand more as I read more explanations
Cheers
