The only reason ‘dark energy’ and ‘dark matter’ were MADE UP by scientists was to explain why their theories about the Universe were not matching the reality of the Universe.
In the picture show at the lead of this thread, there are ‘blue’ (approaching) galaxies and ‘red’ (receding) galaxies. The BLUE are coming towards us, the RED are moving away.
YET, the Big Bang/Expansion theory says that all the galaxies are moving AWAY from us , and from each other. Why, then, are there ‘blue’ shifted galaxies?
Per this article, scientists have three things to deal with:
SIZE
DISTANCE
LUMINOSITY
If you have TWO of those factors , you can deduce the THIRD.
Scientists are using just ONE of these factors to get the other two. That means they are making an ASSUMPTION about the SECOND factor. Then they say that assumption is based on the FIRST factor.
I would say the only evidence that is mounting is that we still do not understand the makeup of the Universe very well.
“In the picture show at the lead of this thread, there are ‘blue’ (approaching) galaxies and ‘red’ (receding) galaxies. The BLUE are coming towards us, the RED are moving away.”
The blue just aren’t moving away as fast but all are moving away.
There is no law that forbids galaxies to have their own speed. Imagine two idle cars on a rubber band. Begin stretching the rubber band and those cars begin moving away from each other. However if you start one car and drive toward another one you can overcome the stretching of the band and approach the other car.
It is actually known that galaxies have their own speed within the Universe and they can collide.

Did anyone claim that we understand the makeup of the Universe very well, just well, or passably good? As far as I know, very little is known about the Universe. The criteria of declaring your knowledge to be of the "very well" grade is when you can make your own little Universes, even if they are not perfect.
