Re: A Physicist Who Denies That Dark Matter Exists
#2Good read about a contrasting scientific view of dark matter.
I also found this quote very relative to this age.
"Why not? What’s the big deal? If something doesn't work, fix it. I wasn't trying to be bold. I was very naïve at the time. I didn't understand that scientists are just as swayed as other people by conventions and interests."

#3> "If Newtonian physics can’t predict the fixed curves, perhaps we should fix Newton, instead of making up a whole new class of matter just to fit our measurements."
I've always felt this way about dark matter, but as a lay person with no background in physics, it's an opinion I'm hesitant to express.
if you have a model that predicts something, but the prediction is off by several orders of magnitude, the model is wrong. no other field would invent invisible stuff to explain that the model is still right. (well, maybe finance)

I have always had the same inclination. It seems like a classic candidate for using Occam's razor. Would love to hear someone who knows more about physics weigh in with a more nuanced viewpoint.

Ok, but physics has had a long and fruitful history of inventing invisible stuff when theory and results disagree. I mean, have you ever seen an atom? A proton? A neutrino?
Scientific theories are generally not just amalgamations of tweaks. General relativity is internally consistent, explains so much, and just got a huge boost last year with the first detection of gravity waves... which BTW are invisible stuff that was invented based on theory. It is not lightly cast aside.

The reason why is so much of the theory is right that knowing how to fix the correct pieces to include the new is the difficult part. As a Theologian/Philosopher Degree holder I love these debates. I think there might be more in the Philosophy side then people care to accept.
> "But if it does turn out that a new theory of gravity is needed, what kind of theory would it be? How could it correctly describe the motion of the bodies in the Solar System, as Einstein's theory is known to do, and still give us the different prediction for the universe that we need?"

Same feelings here. I genuinely do not understand how adding unobservable objects would be the right approach instead of just fixing the equations.

It's also worth pointing out that several similar 'holes' in theories have turned out to be correct. Things like missing elements in the periodic table, and fundamental particles like the Ω− baryon or the Higgs boson, where all things that seemed like holes in a theory, but were later discovered to exist.
