And you have forgotten to read:
3.7 Lyman-alpha forest
Is it a quote from Dark Matter scripture, because is sure doesn't seem to be relevant to anything. It appears that an object in faster time will experience a slight shift to the red as its velocity does not increase as fast as light.
By itself Lyman-alpha_forest it is neutral, either dark matter or GDT can account for it.
And if you want to say something proves the existence of dark matter show the ******* math. Show the gravitational model. No appeals to authority. And is gibberish, the biggest word in your dictionary?
One change unifies several problems and solves them. Dark Matter allows you to predict, what? It is an answer which leads no where.
Does dark matter explain why nebula expansion velocities increase over time.
Does dark matter really answer anything? Will it tell you why 1987a will expand more quickly as it gets older?
What is the closest observation other than the galactic velocity curves which (I can also predict) that supports the existence of Dark Matter. What, you don't have anything closer?
Can Dark Matter explain the inflation after the Big Bang?
Can it explain where it was last night. or the night before , or where it is in this solar system?
The first problem you have is to prove is the existence dark matter. Inferring from faulty computation, which has shown itself to be further removed from reality with each new observation, is dogma, not science.
