Dark energy...if that's not a special pleading, what is? By which I mean the very models themselves (everything coming from a singularity), though perhaps interesting and worthy of investigation, are really not all that much better than brane theory musings, in some regards, for this abundant dark energy itself is little understood, although it needs to be present for the models to work.

As one link (concerning "electrical universe') provided earlier pointed towards...the very observations themselves which are used in the calculations, could well be themselves fundamentally skewed.

Dark energy...if that's not a special pleading, what is?

The question being is there such a thing as 'dark energy' or is there simply some wrong with how we're looking at things. Similar to how my old Chem1A prof complained about the 'neutrino', saying it was just a fudge excuse to cover up an error in the model.  What we know now is that using the idea of neutrinos has come in pretty handy over the years. 

We'll see how this 'dark energy' thing works out...
