Re: How far can we see?

According to the theory of space expanding faster than light (as per inflation cosmology), what is it exactly that is supposed to be expanding? If space is not simply empty volume*, what then is it supposed to be? (Of course it is not empty where "stuff" exists *in space*.
This is half the "what is spacetime?" question, and it has never been answered either after over 80 original pages of that (now closed) thread.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.
