Akson, I have to ask: what exactly are you trying to figure out? This thread is difficult for me to parse, because it seems like every time someone tries to help guide you down a path that would be beneficial to your understanding of astronomy and cosmology, you move your goal posts and/or argue for the sake of arguing.
I don't think you're trolling, and judging by the very patient replies from other posters, many of them don't seem to think you're trolling, either.
But at this point, I feel like it might behoove you to refine your questions. I'm honestly not sure what your questions really are at this point.
It's fine to question the establishment, but to utterly reject the establishment because it doesn't have the answers to every single one of your questions is short-sighted.
If you are looking for Absolute Truth, you won't find it here, nor on YouTube, nor... anywhere, really. It won't be beamed directly into your head. Science is a process of observing and understanding. Is it a perfect process? No, but until there's a major paradigm shift, it's the best process we humans have been able to come up with in regards to understanding the world around us.
