We could preface every sentence with "According to the current mainstream version of Big Bang Theory,..." but that would make the discussion more cumbersome.
True, but it would be more accurate which in my opinion is more important to those of us who are trying to learn a few things

(such as myself)
But you would still see a preferential direction in the motion of the visible galaxies away from one "side" of the universe. But that is not what is observed.
I wonder if we'll ever figure it out
I mean logic states one thing and if observation evidence doesn't support it how do we marry for a solution? Is our logic flawed, or is our observations flawed, or both?
I think this is a misunderstanding derived from how science appears in the public media. If you review scientific papers, you'll see a keen appreciation for uncertainties.
I agree there is a misunderstanding because the media potrays theories/statistics as facts which brings me back to my original whinge
You can 'forgive' the media for playing with the truth because we expect them to an give them the repect that is due to them (i.e. almost none) but I don't like people who love science to make the same mistake.
Unlike the everyday usage of the word 'theory' (guess), a scientific 'theory' is different. A scientific theory is built up from the facts and has passed peer review and confirmation tests. And then further testing and modifications go on...
A 'scientific theory' does hold more weight than other theories but it should always be stated as such.
Note that it's not Science that claims to have Absolute Truth.
Not yet (the search for TOE?)
Also note that 'Man' has to proceed as best we can and correct ourselves when we err. We shouldn't, IMO, throw up our hands and say it's impossible to know anything.
It's impossible to be perfect but it doesn't stop us striving to obtain it. It is impossible for us to know something for abolute certainty. If we take that as a given it becomes irrelevant (much like a common denominator) but we should assume that because we haven't proved something wrong then it's correct.
You see where I'm coming from? I don't want to be picky but there is usually an alternative explanation for observed phenomena. I thought of reasons why the Universe expansion was accelerating way before someone notices a puslar was red-shifting (1987-1988 graveyard-shift when I was on guard in the Army.
THE TOP PHYSICS STORIES FOR 1998 were, according to us, the realization (based on observations of distant supernovas) that the cosmological expansion of the universe is not only not slowing but actually accelerating Source: http://www.physics.auburn.edu/~wersing/SN%20%231
When I read that started to think about alternative solutions to the observed evidence which led me down to light traveling through varying space/time densities all of which is plausible, and I've never once believed that I could be correct it's just that if I can think of alternates then surely most others can also. But they won't even consider it if they believe something to be a 'fact'.
