Do enlighten us.
I’ll enlighten you. It’s called a testable and falsifiable hypothesis. It’s an important part of science. Dark matter is a product of insanely hard mathematics.
But if an input is wrong, or the equation is a false construct, the math cannot predict a thing.
But that aside, a hypothesis is made based upon observation. The resulting equation describing that hypothesis tells you there should be dark matter. It tells you that that its 84% of the universe. You look everywhere, in every possible way. But you cannot find a single particle or sign of it.
At that point in science, you have to assume your hypothesis may be wrong and go back to the beginning, and test your way forward again.
But what you may not do and still call it science, is to say “we didn’t find what was predicted, ergo, it’s invisible”, and cobble on more math to explain THAT.
This is precisely the magical thinking we ridicule young earth creationists for. When confronted with the amount of time it takes a light to travel from a known star exceeding their date of 4500 years, they tell us god created the light in mid flight. This is their way of reconciling the observed, with known physics. It’s childish.
The logic of the lack of evidence of dark matter, but still believing in it, is also found in the Malleus Maleficarum.
Dark matter appears to be the same.
It is set up now to where nothing can falsify Dark Matter. If it isn’t found, then more magic is ascribed to it. The one conclusion you may not reach, is that is doesn’t exist.
Math is fine. Mathematics predicted to Ptolomy the diameter of the earth. He turned out to be accurate to within 1%. His math described a reality. This is science.
Dark matter is much more akin to the “science” that proved the existence of witches, etc. It is deeply flawed and in another 200 years people will laugh at us.
