Or in a more real reality scientists made a proposition beyond any evidence they actually had in hand.

If a scientific theory or hypothesis has to first be proven against evidence that will be brought up in the future, then there would be no more science. How can you demand that science be perfectly accurate all the time, down to the last detail, when all the scientists have is the currently available evidence? In this case, no one could have possibly known that there was a massive nebula out there to disprove the cosmological principle because no one had discovered it. So how can you call it bad science if you have the advantage of hindsight?.
No theory is asked to be tested against any future evidence and I never stated such. A theory has to be backed in it initial point by some experimental evidence otherwise I can assert pink fairies take everything that comes up missing and it would require that you disprove it to eliminate it from consideration. So if you and they wish to assert that the universe looks the same from anywhere in the universe then guess what... You or they have to provide some evidence to initially back the hypothesis and further it must be repeatable by others. So lets see how does one propose that the universe looks the same from anywhere in the universe without having been to anywhere but here? and how would a test be repeatable?.
And note this is not hindsight when we can all see up front that there was absolutely Zero evidence to back such an assumption in the first place. Here check this out... watch carefully now.... Produce the intial empirical evidence to back the hypothesis and is repeatable which backs the concept to the point where it became a logical conclusion to be a principle and a viable theory........... You have the rest of your life to answer that question. I'm not holding my breath though. the funny part is that others get to see you argue for something that you in no way shape or manner can back but its your argument so keep the words coming.
Science isn't science if the proposition is untestable.

Without looking too far back I am gonna go out on a limb here and say that I did not assert any such range of references in any post in this thread so I will leave this strawman you just made up for you to kill any way you think backs your position.
So what evidence was available for any scientist to assert the cosmological principle?

since you used wikipedia, you should just read a little further down the page to get to the observable evidence and reasoning for positing the cosmological theory:
The cosmological principle is consistent with the observed isotropy of: (i) the celestial distribution of radio galaxies, which are randomly distributed across the entire sky, (ii) the large scale spatial distribution of galaxies, which form a randomly tangled web of clusters and voids up to around 400 megaparsecs in width, (iii) the isotropic distribution of observed red shift in the spectra of distant galaxies, which implies a uniform expansion of space or Hubble flow in all directions, and (iv) the cosmic microwave background radiation, the relic radiation released by the expansion and cooling of the early universe, which is constant in all directions to within 1 part in 100,000.[3][4] For example, deep sky galaxy surveys, such as the Sloan Digital Sky Survey[5] or the 2dF Galaxy Redshift Survey,[6] combine line of sight galaxy positions with red shift data to produce three dimensional maps of galaxy clustering across an estimated area over 4 billion light years wide (a red shift radius of z > 0.20); statistical tests applied to these maps confirm that isotropy applies to different viewpoints within them.[7] The cosmic microwave background is the same from all parts of the sky, yet in cosmological theory these must have originated in completely different parts of the early universe.[8]"
See? They made observations and calculations and made a statement that was consistent with what they saw...welcome to how science works. And indeed, it was testable in the sense that anyone could look at their evidence and see that conclusion from it, and until recently no observation of the universe seemed to violate the statements made.
See they looked from our vantage point in space and made an assertion based on that look which encompassed the universe. They stated specifically that from anywhere in the universe, the universe would look the same so no matter how many observations they took and how many rationalisations they made the fact is plain and simple they never checked the view from anywhere else in the universe to check and see if their initial assumption was correct. Essentially they made an assumption with no way to test it when it was made. Thus and therefore it is an untested hypothesis with no more traction than pink fairies. It is like asserting that all swans in the world are white because all the swans you can view from your window are white...
Should we make a principle that encompasses the universe based on a single point of reference that is not empirically justifiable until someone can travel far enough into the universe to give other points of view to confirm or deny the assertion?
You are certainly welcome to assert that such is a reasonable way to perform science but there are a great many who do not agree with such a method as being scientific. There are multiple universes right? the big bang occured when two parallel branes collided right? all part of cosmological hypothesis with absolutely no way to initially test them. Should we make them principles too?
In any scientific endeavor one must first provide evidence for an assumption that is repeatable by others before it is a truly an acceptable scientific proposition.

In time, the vast majority of scientists that saw these pieces of evidence were convinced that their reasoning was sound. The tests would stretch over the next century or so, and continue today. Darwin and others made predictions about heredity, systems of heredity, the fossil record, natural selection and other forms of selection. To this day, the basic predictions of evolution have not been contradicted by any evidence out there. What you seem to completely lack an understanding of is that a "test" does not need to be a stereotypical "chemist mixing together chemicals in test tubes and seeing what happens."
And yet the evidence is being shot down one by one as we are able to look futher and further into what life is really composed of. You can cetainly go through life believing that nothing has been eliminated from darwinian theory but you are becoming a very small percentage amidst a volume of those who are looking at it with a critical eye and they don't see it that way. As I am showing in my 3D thread, mechanically there is no evolution until there is replication and replication of 3 dimensional form such as that exhibited by living forms has an irreducible minimal complexity that is not logically reachable by chance or forces of nature on their own. To form a 3 dimensional structure you must be able to control substrates in all four dimensions of our reality. You are welcome to come challenge that position if you feel your argument has logical value against it.
