More than weird, but scary! Terrorfying, in some respects.

Part of me rather hopes that the physics which these measurements are taken off of is debased, or surifficiently revised.

I rather do like the balloon analogy, though. As the surface area- the very particles on an ideal, thin balloon- stretch apart as it expands, this analogy does correspond with the expanding universe so far as I can see.

Full Circle's numbers seem to gybe with the 'net- the universe is 156 billion light years wide, but 13.7 billion years old. This means that the universe has to have expanded at 11.7c (c = the speed of light), if the expansion were linear. Since most of this expansion happened in the inflation- the inflation must have occurred at some multiple of 11.7c since no star is moving away from any other star at more than c- I suspect that it's a fraction of c. Look at the bright side- finally an example in nature that shows that faster than light travel has to be possible.

...how would you try to explain to a class just how big in human terms that the Universe is?
I mean as good as you could and trying to put it on a scale that humans could understand.

Well....

It's bigger than big...and well...uhhhmmm...it's large....
