[Hps] [BDXlist] Has the dark matter misery been solved?

[Alexander Murphy]

Hi Marco

My understanding is that this result refers to the ~2.5% overall energy density that comes from normal baryonic matter
but which so far had to been observed (as opposed to the ~2.5% of normal baryonic matter that has been observed,
in the form of stars, planets and dust). It says nothing explicitly about the ~25% of the overall energy density that
is in the form of non-baryonic matter... except to provide further support for the general models that describe the 
whole. So it’s really further support for lambda CDM (and similar… with the possible ‘tension' in the Planck data)

So no, the dark matter mystery has not been solved. Quite the opposite.
