Is this really notable? Some brief interest in popular media and then nothing. In fact, it seems rather FRINGEy. (talk) 18:39, 3 February 2012 (UTC)

Brief interest? Please read the article: 129 years since the first discussion of the topic in a peer-reviewed journal by professional mathematicians is not just "brief interest in popular media". Boud (talk) 17:41, 16 February 2013 (UTC)
Sorry, I struck out a few words in my previous comment because the previous structure of the article made it sound like the space was invented only 8 years ago, and the fact that it's 129 years old is mentioned as a technicality. (Anyone new here should still read the article, of course :) .) So I understand the concern.
I've done a brief, quick restructure of the article so that it first focuses on the main thing: this is one of (maybe the?) oldest known hyperbolic 3-manifolds that can be given a constant curvature. 3-manifolds are an important part of mathematics, independent of any application in cosmology - e.g. see Grigori Perelman. The cosmological application is part of the peer-reviewed scientific literature in a serious journal, but the mathematical object exists independently of that.
