Donald says:

Does the discovery of dark matter affect the initial conditions of the big bang? Obviously there was much more gravity, so would the primordial soup need to be hotter?  Would that have changed the initial temperature that then was cooled by the expansion to the current cosmic background radiation?  And did the previous thinking of a 'flat' universe become closed because of much more gravity?  And how does that reconcile with the accelerated  expansion of the universe due to dark energy? Because this last observation defines an 'open' universe. I am so confused!

Can you help?

I don't believe so; it fits with the theory...
