If the Data doesn't Fit, change the Rules a Bit:
In effect, astronomers are now saying that many of the closer galaxies are red shifted because they are moving away from us, but the furthest ones are blue shifted -- not because they are moving toward us, but -- because they are younger. In other words, since the blue-shift (for-furthest-galaxies) data doesn't fit with the red shift theory, for objects that are supposed to be moving away from us, and since we are not ready to completely dump the Big Bang, then we'll simply change the rules a bit, by saying that the furthest galaxies are blue shifted, not because they are moving toward us, but because they are young, while the red ones are red (not because they are old, but) because they are moving away from us. In other words, they want it both ways.
For if the Universe were indeed expanding, and if the galaxies were all created as the result of a Big Bang, then they would all have formed at about the same time: meaning that the furthest galaxies should have the highest degree of red shift (and actually be red, as opposed to blue). But since they don't, astronomers are now saying that the blue color has nothing at all to do with their motion, but is simply a sign of their age.
And what about this "Dark Energy" and "Dark Matter" that know ones seen or knows anything about!
“Astronomers have a problem. Whenever they study the large scale structure of the universe, it soon becomes clear that the amount of visible matter cannot possibly generate enough gravity to hold together the structures they can see. Things like galaxy clusters and even galaxies themselves ought to fly apart given the amount of ordinary matter they contain.”Something else must be holding these things together. So astronomers have dreamed up the idea of dark matter — mysterious, invisible and non-interacting stuff that fills the universe, generating the gravity necessary to hold everything together.”According to the latest picture of the large-scale structure of the Universe from the Planck space mission, ordinary visible matter makes up just 5% of the total mass/energy of the Universe whereas dark matter makes up 27%. The rest is the even more mysterious dark energy. To make the numbers work, astrophysicists tell us that our galaxy ought to be at least 80% dark matter.”
