“Finally this is being admitted.”
____________________________________
The discussion of this notion of ‘dark matter’ and its many possible influences is not new. My university Astronomy 1 class played with these concepts. That was in 1969.
These new ideas and observations are important. (If, at any rate, you actually consider astronomical research important.)
I agree they are not new. What I am saying is this was not presented in places such as high schools and to the general public, instead the science community kept pushing known discredited theories with way more credibility than they ever should have. Take for example the overuse of “Scientific Consensus.”
Science needs to get back to being ok admitting it “doesn’t know” a lot of stuff and stop presenting theories and consensus as unchallengeable by the common man.
