No worries, I don't expect many people have an understanding of what superposition actually means.
The Lemmy crowd probably skews towards those that are likely to understand it, but you never know.

This is just a misunderstanding of superposition.
A superposition is being in all possible states before "collapsing" into a defined state, after interacting with something (a measuring device).
So Schrodinger's immigrant will be in all possible states; they are obviously lazy welfare bums; whilst simultaneously taking all the jobs; and being so poor that they eat your pets; and having the time to organize groups to go raping; whilst also being trustworthy enough to be a housekeeper or nanny
We know something is out there; galaxies are rotating far too quickly for our understanding of gravity to be correct. This is based on the observable matter.
For the galaxies to be rotating at the speeds we observe, we need approx 5 times the matter we see. So it is not like we have missed 10 - 20% of the matter that interacts with electromagnetic radiation, we would have had to have missed an extra 500%
As someone else pointed out, MOND is the next most promising candidate, but it has major issues even explaining what we see. Which is why it hasn't received widespread acceptance.
I don't have an answer; I have a few ideas. It maybe that something MOND adjacent is the answer; i.e. on the largest scales spacetime "relaxes" more when there is nothing pulling on it. So near galaxies and clusters spacetime is under more stress, this stress could equate to spacetime curving more on galaxy sized scales. But on the small scales we work on the extra stress will be almost invisible.
But as for us figuring out what "dark" matter is in your lifetime, unless you are already in your 80's; I think there is a very good chance. The only thing we know for sure about dark matter, is that it interacts with gravity (spacetime). We are building some pretty epic gravitational wave detectors, bringing the detection threshold lower.
To be fair, you never forget your first. Amiga workbench for the A500 was some of the best computing...
If cosmic inflation is correct, probably not. Inflation is our best theory of the beginning of the universe.
According to inflation, spacetime expanded exponentially from an infinitesimal point to many billions of light-years across. As far as we can tell, the universe is expanding again but at a much slower rate, due to dark energy.
Spacetime survived the inflationary period, so it looks like it doesn't have a "tear" mechanism.
Another way to think of it, is to assume once torn, what is it tearing "into". If you rip a bit of fabric, you look through to the other side, nothing special. If you tear our 4-dimentional spacetime, what are you looking at when you look "through" the ripped portion? This implies that out 4D spacetime is somehow existing in a higher dimensional reality.
+1 for great use of "conniption"
Good choice on Mint.
I have been using Linux exclusively (personal) since 2008, distro hopped for a few years then settled on Ubuntu, until they shot themselves in the foot with 22.04 and the snap debacle; moved to Mint (after trying Pop, MX and a few others).
I have to say a big well done to the Mint devs, it is better than Ubuntu ever was; part of this is newer drivers etc...but it is very polished and it gets out of my way and lets me do my work.
Been working with the various flavors of Windows in a work capacity over the same stretch, in my opinion windows peaked with XP, 7 was ok, and 10 is also ok. But it really has been down hill since XP was retired.
Long ago when I worked in supermarkets, our 12 item line was a hard limit; the scanner stopped working at 12. If you had more than that, it was your hard luck item 13 simply wouldn't scan.
Many times this caused problems, mainly for the customer.
Customer: Hey it is only 2 more items.
Operator: But I can't scan it, the scanner stops at 12.
Customer: But it is only two more items!!
Operator: I understand that, but the scanner won't take them.
Customer: FINE, just start a new transaction!
Operator: If you will please go to the back of the line then.
Customer: WHAT, but I'm here now!!!
Supervisor: What seems to be the problem here?
Operator: More than 12 items.
Customer: I ONLY HAVE 2 EXTRA ITEMS!!!
Supervisor: I understand, if you could please go to the back of the line to get the extra two items, we will be happy to help you.
Customer: WHAT THE FUCK, IT IS JUST TWO EXTRA ITEMS!!!!
Supervisor: If you want, them in one transaction we can cancel this one and move you to a full sized checkout.
Customer: ...ENRAGED RANTING....
Supervisor: If you are going to be abusive to me or my staff, I'll have to ask you to leave.
Word of that type of thing gets around, for the number of people through the supermarket, the total number of incidents was very low. But they happened at least once a week.
This but realistic.
Swap the order of the cutlery draw, put the spoons where the knives are supposed to be. Be the chaos in the world that you want to see.
Cactus Outdoor.
I had the original pack now called Vacuole, used it for a long time 10 or so years, lost it one time when moving houses. My boys have one each for school now, I expect them to last for the duration.
I have two pairs of supertrousers and two pairs of hangdog shorts, all have lasted 6 years so far, daily use in summer / winter for the shorts / trousers.
The stuff made in the Christchurch factory is epic.
You are applying too much classical thinking.
Something in superposition isn't in some unknowable but definite position before measurement.
It is all possible states, at the same time.
Einstein famously did not like the implications of QM, saying "god does not play dice with the universe", though his work on the photo electric effect helped pave the way for QM.
