In standard model Cosmology ordinary matter is only 5% of the total mass - energy of content of the Observable Universe.
http://en.wikipedia.org/wiki/Dark_energy
Since 95% of the mass energy content of the Universe is unknown with uncertain properties, can we really be certain CMBR originates from the 5% of ordinary matter making up our Universe or could there be other possible radio sources of some kind in the remaining 95%?
Also are there possible implications for any other theories, as a result of such a large percentage of the Universe being unknown? At face value it just seems that we know very little about what makes up the vast majority of the Unverse and so I just wonder if we may be making any assumptions.
