  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.

    “Producing dark matter”… and you think that’s a valid question!? We don’t even know what causes dark matter, and your ignorant ass wants proof on what we cannot yet 3xplicitly define?

    Shame on you, and shame on anyone who upvotes such a blatantly ignorant expression of doubt.

      It was a factual statement, not a question. There has been no production or “demonstration” of dark matter.

      We don’t even know what causes dark matter, and your ignorant ass wants proof on what we cannot yet explicitly define?

      I’m not asking for proof. It was claimed that dark matter proof has already been demonstrated. This is false.

      Shame on you, and shame on anyone who upvotes such a blatantly ignorant expression of doubt.

      You can’t shame science. The only reason a “dark matter” hypothesis exists is to shoehorn observed data into existing cosmological models.

        You stated no fact, dummy. Dark matter has been proven to be an existing phenominon, not something we know what it’s made of, or we’d call itthat instead. It’s called “dark matter” BECAUSE it doesn’t interact with light. We can observe it indirectly, with actual, literal proof.

        There are galaxies whos spin works fine with newtonian physics and those who do not. That is the most basic explanation of why we know it exists: because there are differences observed around the universe that can be explained if there is a form of matter that we cannot directly see.

        I shame your pitiful ignorance that you repeatedly show off so proudly. Shame on you for daring to spread ignorance.

  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 exists 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.

    Am physicist. Quantum particles are observable. Often things are observable because you can observe their effects. Can’t measure a top quark, but you can measure the electrons and photons when it decays. And their energy and how often it happens lines up with theories developed to describe some different thing.

    Theory of everything can’t exist, be abuse Gödels incompleteness theorem. But no physicist doubts that all the microscopic stuff gives rise to the macroscopic.

    The beginning of the universe you can see in the microwave background or something. So again that’s just experimentally motivated theory.

    Some of us come up with random theories because it’s fun. But most of the time the theory is aimed at explaining some thing that we observe and will coincidentally make predictions about other stuff which we can test.

    Finding out how dinosaurs sounded like is dope af from a physicists perspective.

    But with a powerful enough telescope, you just … Like… Fucking LOOK AT the beginning of time. The instant that instants became. There is a lot of theory about why it looks like that (all based on math you could never possibly understand) but it’s not just a bunch of half baked dudes on a couch coming up with “theories” as you seem to use the word.
