the presence of "dark matter" and basically all other phenomenon that we do not have great explanations for are actually, literally and demonstrably real.

Not true. There has been no demonstration, no experimental evidence producing dark matter. Nothing from the LHC.

Something makes dark matter.

Maybe only our imagination. Researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.

Paleontology could only DREAM of having the proof modern physics has.

Dinosaur feathers are the paleontological equivalent of dark matter.

Skulls can provide a huge amount of acoustic information.

I ain't no physicist, but the last time I've checked, it was a theory galore, with theories upon theories about whether there could even exist a single definite theory of everything, with stuff not being observable by it's nature (quantum particles), other stuff not being observable by it's nature (beyond observable universe), and theories based upon the event of literal creation of the universe itself, which is in turn theorized by linearly extrapolating a single phenomenon all the way down to zero (correct me if I'm wrong on this one, shit's fascinating).

Finding how dinosaurs sounded like, on the other hand, doesn't take much theorizing - just take some well preserved remains, approximate breathing cavities structure and model it with something like a pink trombone. I'm oversimplifying, of course, but, the point is, it's miles closer to us, time and space wise, than whatever physicists are rambling about.
