That’s why I suggested you start at the 2 hour mark and watch only 30 minutes. It was Libwhacker who requested to know the video.
I don’t care if you watch it.
There is a discussion in the second video about what the red shift’s really mean. And if they don’t mean expansion of the universe, then that might be why they claim dark matter is not needed. But I view red shift as separate from the heliocentric model. So not sure if that’s why they said that.

And philosophically speaking even if the universe is finite, and you’re the only physical life in it, then you are figuratively the center of the universe, regardless of your proximity to the physical center.

Red shift, which is simply Doppler shift of the visible light spectrum, is how we measure the expansion of the universe. So anything being said in your video about dark matter that is dependent on Red shift meaning something else is based on false premise.
You apparently are 100% absolutely certain that the doppler effect is causing the Red shift. I'm not.
Can you explain why the red shifts appear quantized? Do you assume that the differences in redshift among apparently associated items is always an illusion?
Spectroscopy is not my specialty, but I know this much. Spectral bands in light are affected by the chemistry in the source of the light. Chemistry and physics at the quantum level have quantized signatures. So when we collect data from astronomical observations using spectroscopy, the observations are used to estimate a great number of things including for example, the composition of the star or source of light (burning hydrogen vs helium, vs other gases). Being able to correlate each quantized color band to its chemical source allows us to very accurately measure the Doppler shift on that band.
As to the rest of the mysteries of the universe, I hope you don’t expect FReepers to go off and research all your many questions.
I enjoy a quick discussion on a topic, but I am not going back to school to satisfy everyone else’s curiosities.
Nor am I. But I noticed, you didn't sound quite as dogmatic in that last response as you did in the previous one. Clearly there are some scientists and universities acknowledging that there are some controversies, some anomolies that don't fit.
Creationists have a problem with the scientific community and the MSM reporting of science. It is the same as the problem Freepers have with science and MSM reporting of Global Warming or that Trump has with the MSM.
There is a lot of preconceived bias, even dogma, built into both the scientific community and the MSM. Alternative views tend to be squashed and ignored, with their programs shut down rather than fully explored and explained. It's a lot like trying to get a conservative viewpoint expressed on MSM.
The science is not settled. There is much we don't know. Some of what we think we know, may not be true. I have a sudden desire for Rummyspeak.
The video also had an interesting discussion of the Michelson Morley experiments, with an implication that our standard model is based on the aether not existing. They claim that the US Air Force repeated the experiments in 1986 and actually detected the aether. I'm not a physicist and don't understand the implications, but they might be cosmic.
Regarding your greater curiosities and what is or is not settled science in the real of cosmology (not to be confused with cosmetology), I will just quote Ferris Beuller:
I quote John Lennon, "I don't believe in Beatles, I just believe in me." Good point there. After all, he was the walrus. I could be the walrus. I'd still have to bum rides off people.
What speed is the universe expanding at?
Well Ferris did have a few things figured out.
