Except there is neutrino research going on. There’s also a hypothesis that right-handed neutrinos are significantly more massive than their left-handed counterparts and are actually Dark Matter
A matter of patience

something something seesaw something

If you don’t understand the seesaw
spoiler
The explanation for the observed light neutrino masses that involves massive right-handed neutrinos is called the “seesaw mechanism”, since it kind of works like a seesaw (when mass of right-handed neutrinos goes up, the left-handed neutrino masses go down. Since observed neutrino masses are very very light, like ridiculously so, it was first though that they were massless until it was discovered that they oscillate between 3 flavours, which is only possible if they have mass, these right-handed neutrinos must be quite massive indeed) For the record, I’m not a particle physicist of any kind and I got that information from a couple lectures that I watched that were about neutrino-related things. The supersymmetry camp also thinks that right-handed sneutrinos (the theoretical supersymmetric partners of the neutrinos) could also be a candidate for dark matter. Note the prefixed s, that’s how most of the supersymmetric partners of the observable fermions (squarks, selectrons, sneutrinos), while most of the supersymmetric partners of the observable bosons end with ino (photino, gravitino, and I’m pretty sure they call the partner of the W boson the Wino).

Nah. Neutrinos and NEOs actually exist.

Hi diddely ho, neuterino

We’re trying, okay? It’s not our fault they have all their preferences set to DNI.
CheesyFox@lemmy.sdf.org 2 weeks ago
i mean,if i was a neutrino, i’d have “humans DNI” in my twitter profile

(It’s funny because we can’t stop them from passing straight through the pool.)

i thought neutrinos were currently getting less attention because the huge japanese neutrino detector exploded

The implosion incident with Super-Kamiokande happened in 2001. Repairs were completed in 2006.

“HOLY FUCK, an IMplosion?!”
One of these tubes – each of which contains a vacuum – is thought to have imploded as the detector was being refilled with water following maintenance work.
I guess “vacuum tube crushed by water” needed a bit of punching up.

did they see any since then?

Do you want neutron weaponry? Because that’s how you get neutron WMDs

Dark matter is just matter hidden in darkness, hence we cannot see it. It’s not some extraordinary substance. Mark my words.
IAmNorRealTakeYourMeds@lemmy.world 2 weeks ago
it is because we invested so much in telescopes there was no budget for flashlights

Who downvoted this? 💀
Solano@piefed.social 2 weeks ago
Right. Wish people were more scientifically minded around here. My guess is just the most simple one, and I welcome challenge to it with the mark my words part.

Don’t agree. There is so mucb interesting stuff happening in astrophysics. It’s hard to choose one.
Vera Rubin going online is already giving us a huge boost to detecting near earth objects.
And neutrino astronomy is pretty much still in its infancy. There is still a lot to learn.
We’re finding older and older objects every month. A potential bio signature has been found on Mars. We discovered our third Interstellar visitor. The next stage of the moon mission is about to launch people around the moon in the next few months. The crisis in cosmology is getting bigger and bigger.
Astrophysics is in a great shape.

It's still a few years away, but so excited for the Europa Clipper to get to Jupiter.
Slein4273@feddit.org 2 weeks ago
And Europa Clipper and JUICE will be exciting! I like JUICE a little bit more because of the name :)
Rusty@lemmy.ca 2 weeks ago
Is anyone else concerned that Europa Clipper will get more stupider?
Chakravanti@monero.town 2 weeks ago
The Monolith did tell you not go to Europa. Just Sayan.

Can you define crisis in cosmology please? Trying to learn.

It’s basically a disagreement on the expansion rate of the universe. Depending on how we measure it we get two vastly different numbers. And either our understanding of how the universe evolved after the Big Bang is wrong or we interpreted data from our telescopes incorrectly.
The hope with the launch lf JWST was that it would go away with better data. But it seems to be getting worse.
So that makes it more and more likely that our universe formation theories are wrong. This does not mean that there wasn’t a Big Bang. But it means that what we thought happened between the Big Bang and now isn’t quite right.
So we can expect some great new theories in the next decades.
