There has been many references, from many reputable cosmologists, over many threads, highlighting the evidence and data we have that point to both DM and DE existing in one form or another. I'm really not sure how you could have missed those references, other then ignoring them because they dont happen to fit into your slightly askew model? On both of those entities, consensus is obvious. Your reference to a cosmological dark age also appears to be rather wierid to say the least, considering the many state of the art equipment we have helping astronomers/cosmologists and physicists in general. Perhaps it is just a case of the more we find out, the more there seems to be to still need to know. The Universe is a weird and wonderful place.
