Yeah, it’s quieter so there’s fewer overall responses even in “popular” posts, but it doesn’t feel like anything gets ignored. If a post is interesting, you’ll get at least a few replies even if it takes a few days.
That part is kinda nice - the lower turnover on the “front page” means you’ll have people reading and commenting on discussions for days. If you reply to a 1-day old post on Reddit the only person who might see/reply to you is the person you replied to.
I’ll only be a carnivore on day 1
There absolutely are, but I’m not super familiar with all of the consequences of majorana neutrinos. /u/[email protected] might be able to provide a better answer. My background is experimental nuclear physics, so I’m familiar a lot of experiments searching for beyond the standard model physics, but less so with the theory motivation.
One consequence of neutrinos being their own antiparticles is that it breaks lepton number conservation. This also breaks chiral symmetry, since all neutrinos are right-handed and anti-neutrinos are left-handed. This observation would also imply that neutrinos have mass - which is assumed but would be a really big deal to prove.
Yeah it’s one of those terms that’s unfortunately been co-opted for another definition. Definitely made some of my google searches in grad school feel icky… The physics terminology came first though!
Despite space being “empty” there’s still a surprising amount of stuff streaming through it. There are protons, electrons, carbon nuclei, etc constantly slamming into the Earth’s atmosphere, producing showers of radiation. These cosmic rays are the reason so many sensitive physics experiments ( like dark matter and neutrinoless double beta decay searches) are located deep underground. The earth is a good shield against these cosmic backgrounds.
Even if there was an “isolated” antimatter galaxy, it would get bombarded with matter in the form of cosmic rays. The annihilation photons are a really distinct signal that would be hard to miss. There are a number of gamma ray telescopes in space that map out sources of gammas, and they would have detected an antimatter galaxy if it existed.
If the antimatter galaxies are so far away that they’re beyond the visible universe, then there’s still the big question of why there was a segregation of matter and antimatter early on.
You’re not alone; matter-antimatter asymmetry is one of the big open questions in physics. Most particle processes treat matter and antimatter identically, but there are a few areas where matter and antimatter have slightly different interactions. These occurrences are violations of Charge Parity symmetry aka CP Violation.
There must have been a certain amount of CP violation during the early phases of the Big Bang to explain our matter-dominated universe. But the known amounts of CP Violation are nowhere near enough to explain the asymmetry in matter and antimatter. There are some proposed mechanisms that would violate CP symmetry in sufficient quantities, but these haven’t been experimentally observed. There are ongoing searches to detect these processes, or related processes that would be possible if these existed. Neutrinoless double beta decay searches are one example of these detection efforts.
In summary, there’s a guaranteed Nobel Prize to whoever can answer your question.
The US Department of Energy…
No problem! Also your response just reminded me of one key feature that Arctic has that Voyager doesn’t yet: push notifications.
I used to use Memmy before development stopped. I found Voyager had all the features/UI that I wanted and used that for a while. Recently I’ve started trying Arctic - it’s similar to Voyager but has a few UI tweaks I prefer.
Edit: oh and both of these apps support instance blocking
It used to be owned by The Onion, but it’s since become its own thing. But it’s basically if The Onion was clickbait/buzzfeed.
I am not reading your comment, I am simply traveling through it with my eyeballs. Also your comment doesn’t have gold fringe and therefore lacks jurisdiction.
As annoying as it is to lug a bag around and find room for it, I much prefer this to checking it. There’s the small but nonzero chance your bag doesn’t make it to your destination, plus the added time waiting at baggage return.
As someone who occasionally struggles with insomnia, I highly recommend the Insomnia Coach App for iOS or Android. It’s entirely free (no ads or in-app purchases) and based on Cognitive Behavioral Therapy. It was developed by the US Department of Veterans Affairs, but it’s available and applicable to anyone who has trouble sleeping. It has guided meditation and other tools to help you sleep or identify causes of insomnia.
It requires some effort on your part: you follow a 5 week training plan and keep a sleep diary throughout. However the effort is minimal and again, it’s free. Following the sleep plan significantly improved the number of nights that I have good sleep.
Yeah they had the first functional iOS app long before anyone else (Mlem had started earlier but stalled for a while). I recall some of the Memmy developer’s comments saying they had learned a lot about app development since the first beta and had big plans to overhaul the code base. I’m assuming this turned into too much for them to handle, especially as an unpaid gig.
It’s a shame Memmy’s been abandoned, but I’m still super appreciative of the developer for making a workable Lemmy app back then. It definitely helped ease the sting of the transition from Reddit.
There are free options for federal taxes: https://turbotaxsucksass.org/ (yes that is the real URL, the site was initially created by John Oliver for a Last Week Tonight episode).
What state are you in? Many also offer free options for state taxes.
I’m guessing they signed up for HP Instant Ink, a monthly subscription service that monitors the ink levels in the printer and automatically mails you refills.
If you buy an HP printer, they HEAVILY promote this and offer discounts/free trials. I declined, because fuck that, but I could see someone agreeing and forgetting about it.
I will run this thing until it dies.
Good luck with that. My 2011 MacBook Pro still works. I’m pretty sure it’ll outlive me.
The exact same thing happened to me while I was deplaning, a few years prior to Covid. Full face sneeze with no effort to cover their mouth or nose, at like 1 foot away. So I still wear a mask on planes and in the airport.
