The conclusion in this case is also supported by a preponderance of the evidence. But yes, there is always the danger of deer-in-headlights if you accept a certain thing long enough. Is it called confirmation bias?
In regards to dark matter and dark energy, by the way, I think most accept that they are just running theories for now. They’re just terms for observable things that we can’t explain yet. One of the leading proposals to explain dark matter is in fact that it doesn’t exist at all. It’s called MOND (modified Newtonian dynamics).
Good discussion.
My view is that we in one of the times in the history of science where we are getting close to major new discoveries—in the field of cosmology.
The “trick” imho is to accept data as data—and not be in any rush to create new theories to explain it.
There will be plenty of time for that.
