Dark matter and dark energy is a gap in knowledge and should not be presented like a fact, but as a temporary constant added to human models of universe to make them actually work. It is like a boy calculating physics homework, only to be 30% off, so he will add some constant to get to result he wants. It sounds ridiculous, does it? Well dark matter/energy is that constant to get result we expect.
