Very nice video. Explanations a layperson can understand. It is nice to hear someone talking about what we don't know and what we don't understand rather than acting like they know it all and presenting everything as fact to the general public.
Yes and no. If only expensive projects involving dark matter get funded and they continue to look for something that is a wrong idea and they remain closed-minded and try to make sure they find what they are looking for, that is a costly error and not good science. If they need a paradigm shift and blind themselves to that and keep adjusting the model to make it fit when it doesn't, that is bad. Science needs to be open and questioning. In any kind of science, what we think we know today becomes invalid and inaccurate over time. That is the nature of science. Karl Popper points out that a scientific hypothesis can never be proven right once and for all. We can only say we believe it is correct for now, and we always need to be open-minded and ready to give up our cherished ideas when evidence points to the contrary. Hypotheses can only be falsified. The problem I see with scientists in so many areas is that consensus hardens scientists, so they do not remain open-minded. They fight against evidence to the contrary and blind themselves rather than remaining open. There is also the problem of funding. If you go against the status quo, you will not get funding, and, in fact, you will risk your reputation and career. That is not healthy to further knowledge and understanding. I am not a scientist. I just try to keep up with what they are doing, and I always question when I see or experts in a scientific field report that their field is trying to ignore evidence to the contrary. I am more easily able to see it in medical science, especially involving nutrition as I understand that field better. But I read about it from outliers in the physics community, not wackos who don't know what they are talking about, but genuine astrophysicists who don't agree with consensus.
@@Jan96106 There are other scientists baffled by new discoveries. Science is the best educated guess "most of the time." Obviously with the universe it is just that. Many scientists have belittled Einstein and some of his theories just to find he was right.

This started out nice and loud. Then it got quieter.
This man stated "much of what we know about the universe may have been wrong." Billions after billions of dollars are wasted on space. wow

He still didn't tell us why the distant SNs were fainter and therefore further away than expected.
Relative to what? Their CRS?
16:00 The standard awful misconception that a static system will collapse due to gravity.
The nature of orbital structures prevents this completely.
