Serious question: (and I am being 100% serious, it is a good question). How long should scientists search for "dark matter"? They thought they found it a few months ago but then they went silent. So now they are looking for a different type of "dark matter" than before.
Once again, what's going on has evaded you completely. 'Discovering dark matter' doesn't mean what you think it does - it's not like we're going through candidates like
"Pink, furry, smells of cheese... not there.
Purple, furry, smells slightly less of cheese... also not there.
...
Pink, not particularly furry, possibly smells faintly of cheese... pending."
'Dark Matter' itself is the term used for something - whatever it is - that accounts for discrepancies between what's observed and what we predict based on what we know. It's 'dark' because it doesn't interact with light, and actually people have moved on to calling it 'dark energy' because of technical reasons. You basically don't understand the search at its simplest level, from what I can tell.
Hopefully scientists will actually find real honest pure Dark Matter (no quotes) in a year or two. (I wouldn't hold my breath on that btw). But let's suppose for once that I am right and scientists are unable to find "dark matter". At what point do scientists say, "you know what? we can't find it. all our empirical math and data points to the existence of dark matter but it doesn't exist. we need to rethink everything because something fundamental is wrong here."
Congratulations on basic science. That's what *everyone already does*. Have you not seen the bazillions of different theories unifying gravity and the other fundamental forces?
I am concerned because the way science operates, there is no going back.
Wrong.
Everything that has been proven has been proven.
Entirely tautological, so this is as useless as something that's wrong without even the decency to be properly incorrect.
According to the math, there should be dark matter. And math is never wrong (I am being serious). But if somehow the math was correct but pointed in the wrong direction from the get-go, then how do you go back and fix it?
Build a new theory, test the new theory, see what happens.
Again, I hope they thoroughly and 100% convincingly discover Dark Matter and send me, the EU theoriests, and every other crackpot back with our tails between our legs. But in the case that one of these other fringe, crackpot theories is correct, then is it even possible for science to go back and fix itself?
It's hard to say, because obviously at no point in history has science had to correct or revise any of its statements, but should that horrible day ever come I think we'll cope somehow.
Let's say the EU is right about plasma being the main driver for universal motion. How would science account for that? Science has already calculated gravity as the main driver. There is no going back is there?
In order... no, I won't, because that sentence as you've stated it is correct only in a grammatical sense and conceptually you're talking a lot of nonsense... cf. previous... cf. previous... and yes, there absolutely is, and if the possibility of a change in science seems like unfamiliar territory to you then you have simply actively unlearned the history of science.
Is there a historical reference we can fall back on? Is there an instance where science has been proven wrong on such a large stage?
Classical mechanics versus relativity versus quantum mechanics (partially resolved), the ether, and... can't you just get a book for this?
This is a good question (snip)
No, it isn't. It really, truly isn't, and it only seems that way because you've basically developed brain-Teflon and developed such a thorough lack of understanding beyond the construction of sentences that artificial intelligence textbooks worldwide can probably use you as a counterexample for any statement whatsoever.
and it concerns me greatly.
It only does because you're completely clueless... not just about the possible futures of science, but also the basic principles and apparently literally any of the history behind it. It concerns me greatly that your 'talking' to 'reading apparently anything that isn't bullshit, even when directed clearly to reputable sources that would have saved us all the trouble of answering questions schoolchildren could answer' ratio is so enthusiastically the opposite of what it should be.
Go away until you've caught up on the basics.
