While I love reading articles about science they are almost always simplified to the point if being frustratingly meaningless. Phrases like "as the universe expands" loose all meaning when you're talking about time being converted into space. If only there was somewhere that explained the implications of what seems like this beautifully elegant idea in an equally elegant way... sigh
At the very least I wish we had a 'grellas' for space and astronomy lurking around here, just waiting to do a drive-by and drop a mega comment that answers all of our questions.
I won't hold myself out as that much of an expert - cosmology was never my specialty and I haven't been a practicing physicist for a decade - but see my comment: http://news.ycombinator.com/item?id=2006334
Wow - that post was more than I was expecting - kudos (from a complete layman).
BTW - have you ever done speaking/books on debunking / explaining physics in general? It seems like you'd be a shoe-in for a Brian Cox-type role as a more hip face of physics - though maybe you'd like to avoid that...
Correct me if I'm wrong, but seems like the idea of "time being converted into space" is itself pretty meaningless because it implies conversion happening over time.
I vaguely remember stories of this in a black hole. The "metric" changes. It involves the space dimension becoming time-like (restricted to movement forward) while the time dimension becomes space-like (finite). I don't remember the physical interpretations making much sense either.

Happening over spacetime, you mean :)
