Until it can be proven that 'dark matter' and 'dark energy' even exist, there's little point in going through that exercise. It will only lead to the invention of some other goblins or fairies, that likewise exist in theory only.
Ultimately, such exercises are destructive, as they produce ideas which further solidify the existing cosmological paradigm, which itself, is an enormous conglomeration of unproven, untested, unworkable theoretical constructs, that does nothing to accurately predict or explain observed phenomena in our universe.
The existence of dark energy, or some sort of ‘hidden’ energy, is likely, given the (supposed) fact that the universe is accelerating in its expansion.
