Witam What if DE (dark energy) is not something from early universe physics but instead is directly related to the properties of the CDM (cold dark matter) particles as some sort of negative pressure?

Two articles on this idea: http://de.arXiv.org/abs/astro-ph/0209584 Schwartz http://de.arXiv.org/abs/hep-ph/0209322 Gondolo & Freese

(Varun Sahni et al. had some ideas earlier - last 12-18 months - on how DE and non-baryonic DM could be the same thing, but I think it was just phenomenological. Though I'm not sure.)
