Such detectors will never see dark matter because it is little black holes.
Depending on the size of the black holes these detectors can see them.

The linux developers' mailing lists are not producing anything like scientific papers...
Kind of arrogant no? Linux kernel development mailing lists are producing something immensely valuable with a much clearer impact on economic indicators than your average scientific paper. Comparing them is hard, but it's patently absurd to say there's nothing being produced compared to scientific papers.
Dunno who you're arguing with, I didn't say they didn't produce anything of value. I said they aren't producing scientific papers. Conversations are not like papers. The scientists have conversations (sometimes on mailing lists!) as well. The analog to scientific papers in the Linux world are... scientific papers. And the occasional essay on the mailing list, which---get this---would be more valuable to humanity if it was subsequently reproduced as a paper with references and explanations and the like.
(Notwithstanding the absurdity of academic publishing, of course.)
Re: Biggest dark matter detector spots a single weird particle
#73I think it's cool that there's still unconfirmed hypothesizes, and still unexplained phenomena in the science that's investigating these hypothesizes. I hope this turns into a real discovery about something; but even if it's an equipment malfunction, hopefully it's a lesson that can be turned into improving the detector.
Astronomy/Physics is overflowing with unexplained physics phenomena these days.
Especially after JWT started looking deeper into the early universe.
Re: Biggest dark matter detector spots a single weird particle
#74> Such behavior could require dark matter to be more complicated than just a single new type of particle. For example, the dark matter particle might have some internal structure, like an ordinary atom, so it would only interact if hit hard enough to excite it to a higher energy internal state I get a little shiver imagining that the dark matter might be something like ordinary atoms. Imagine that other 85% of the un…

The premise of dark matter is that it is something with gravity that does not otherwise interact with any of our detectors (e.g. "normal" matter); or that any such interactions are weak enough that it is plausible we have not noticed. By itself, that does not exclude the possibility of dark matter having other interactions which do not interfere with our detectors.
Our observations are much more consistent with a form of dark matter which does not self-interact, or which does so incredibly weakly. Don’t ask me how or why, but this is essentially the universal (pun intended) consensus amongst cosmologists.

#77This is 1σ. It’s fun and interesting, but means nothing.
> LZ physicists estimate there’s about a one in 200 chance the event is a statistical fluke
That's more than 3σ.

Or this[2] 2007 Science paper on ultra high energy cosmic ray source candidates ("anisotropy") that we had to retract because significance started dropping almost the day the paper was approved. It was a fascinating experience as a junior member to follow the collaboration internal conversation and investigation on this, because a lot of extremely principled scientists were clearly deeply worried about losing their h…
Wow haha, that is a lot of authors! Never seen this before!
The ATLAS-CMS joint Higgs boson mass measurement paper has close to 6000 authors: https://doi.org/10.1103/PhysRevLett.114.191803
I think the final COVID consortium report has something like 30k authors.

If this anything like CERN detectors, they get amounts of data so vast that they have to discard almost all of it to be even able to record it. Depending on heurestics you use to discard data you might be discarding what you are looking for and after adjustment will get some new interesting events, but still actually processing the candidates might take a long time.
This raises what is (I think) an interesting question. CERN is a collider, so they are _trying_ to produce lots of stuff, and they do (lots and lots of stuff). They can't write it all to disk, and most of it isn't interesting enough to try. The work being done here falls into the category of "low background physics" --- they aren't trying to produce anything, and actually put quite a bit of effort into doing the oppo…
I think this description is essentially correct.

It's possible that there could be an entirely different charge mechanism that works exactly like ours but they don't interact at all; but the whole premise of dark matter is that it doesn't seem to have any self-interaction outside of gravity.
The premise of dark matter is that it is something with gravity that does not otherwise interact with any of our detectors (e.g. "normal" matter); or that any such interactions are weak enough that it is plausible we have not noticed. By itself, that does not exclude the possibility of dark matter having other interactions which do not interfere with our detectors.
It's very hard to explain the gravitational halo around the galaxies if your dark matter can interact with itself. If it interacted like normal matter, it would have a distribution similar to the gases, and not spread way into intergalactic space.
