Yes this is what I was referring to -- and I don't know what lay language to
use -- Folks help me out here. As the rubber sheet expands the distance
between the ants grows, but the ants are walking too -- such that if the
expansion were to slow or stop, the ant-ant distance would still increase.
But there is still a problem in my head:
You say that as the Universe expands that what ever "stuff" was at the rim
of the Universe shortly after the BB has always remained relatively close to
that "rim" (whether we are talking about balloons or rubber sheets of what
ever dimension) -- eg your ants stay close to the "edge" .
But didn't the
Universe "expansion" initially proceed at a rate >c? The "stuff" even
photons can't travel at >c.
I am confused. In my head the "rim" traveled
faster than the stuff and later (I don't know what "later" might mean) this
expansion slowed down to <c (at least in some scenarios) such that the
photons are "catching up" to the "rim". And if the expansion slows to <<<c
even the galaxies would "catch up"
Where have I gone wrong?
Tom, this is just fine and it surely makes the point to a lay person well
enough, But I think I misunderstand something -- even if the balloon were
to stop growing, the dots still flee from each other. NO??? Help me out
here. I am waiting for Dave Bowman to chime in here. Where are you???
