The sun can’t go supernova because it hasn’t finished fusing hydrogen. When it does finish, it will swell up to a red giant. This has to happen before it can explode, and the swelling process will take a very long time (in human terms).
Secondly, would it even be possible to know in that the sun has exploded?
The meme says “in the 8 minutes it takes for the light to reach us” but that would also be the precise moment in which we learn of the explosion leaving us with no time to make memes.
Which leads me back to my initial question, how, if at all possible, could we setup an early (seconds/minutes) warning system for such an event?
Possibly some kind of quantum entangled alarm system in a lower orbit around the sun?
Completely tossing around BS of course, just an interesting thought experiment.
Quantum entanglement can’t actually transmit information, it just looks like it can sometimes due to how quantum mechanics can get weird.
Get a red ball and a blue ball, and two boxes. Close your eyes and out one ball in each box. These box-balls are now “entangled”, in that you know that the contents of one is not the content of the other.
Send a box to a different country, and open yours. You instantly know that the other ball is red, since yours is blue, but the holder of the other box knows nothing new.
With the QM, it the same basic setup except both particles are in an indeterminate state, and when you look you’re making it “pick” which state it’s in, and it also makes the other one “pick”.
You can’t force it to collapse one way or the other without breaking the entanglement either, so it’d be like red-blue ball, and when you force it to be red, the other ball now has a 50/50 chance of also being red.
My guess for the only way to get some warning would be if the supernova had some form of initial, not-cataclysmic flash or outgassing shortly beforehand.
Superposition is just the “it’s in multiple states at once” part. Entanglement is the property of making how one particle comes out of superposition interrelated with how another one does.
No and yes. If it happened instantaneously then no.
However, scientists are capable of predicting solar flares well in advance. They can do that by looking at what is happening on the surface of the sun. If it was about to explode, there’d likely be some kind of unusual activity there for several days prior to the explosion. The sun is also rather big. So even if aliens decided to blow it up unexpectedly, it’d probably take more than a few minutes for the explosion to engulf the entire sun, meaning that you would have time to send a meme before lights went out.
I’m not really sure what other purpose a warning system could have. There’s no good place to hide if the sun goes out.

The sun isn’t big enough to go nova, period. It will swell up in ~5 billion years when it runs out of hydrogen in the core and starts burning helium. Then the sun will start climbing the fusion chain up to iron and there the fusion reaction in the core will die out. When this occurs the outer shell will kind of just slough away leaving a planetary nebula and an extremely hot naked mostly iron core. This core is a white dwarf and will just continue to glow for a few tens of billions of years until it loses all its heat. No fusion is happening in this bad boy it just glows from the residual heat and the heat is so hot it takes longer than the current age of the universe for that heat to dissipate.
Back to the original point though is that the sun won’t explode in a supernova because it lacks the mass to do that. You need a star that is at least 8 times as massive as the sun in order to get a supernova.
I learned a long time ago that if I act like a dumbass all the time, nobody will expect anything from me and they will be pleasantly surprised when I manage to do something simple.
Bluntly, those are not the same picture. As a dude, I see a couple of important things right away. Most importantly, there’s dividers between the urinals in the second picture.
If there’s room, I’ll still leave a gap, but with no dividers, if there isn’t room to leave a gap, depending on the spacing of the urinals, I might just want to wait until there can be a gap. With dividers, I probably won’t. It’s still not ideal, but dividers make it much more palatable.
Netflix and Spotify actually makes sense to be subscription based. Amazon depends on how often you do online shipping through them since it’s actually free (if you don’t include the fees) to function. I definitely wouldn’t pay for Dropbox but cloud storage and sync pretty much has to be a monthly subscription. If you are going to be against something at least be against to the parts that makes sense to be against of.
Yes, and life still works fine without them…nobody is forcing you to subscribe to Netflix. Keep paying your monthly cable subscription like the old days.
I ain’t got no cable, last time we had cable i watched for 2 weeks and after that everything was just repeating what i had already seen in those 2 weeks and loads of nonsense shows.
I prefer doing things, like learning new skills or doing something active.
I’m autistic and i almost never remember to initiat the conversation, or feel like it’s not appropriate. If any of my friends felt like you do, i won’t have any more friends. And i love my friends a lot and can’t survive without them. Don’t over think it. Each has their own way of socializing. It’s about the journey, not its initiation :)
I do, just not as often. I can’t control it. I do make sure to let them know i appreciate them contacting me though. As much as possible. Also, i don’t understand why the beginning of socializing is more important than the rest of it. Why is me being engaged and interested, continue the conversation, showing appreciation throughout, and making it obvious that I’m enjoying it and would enjoy more in the future, why does that have less weight than a “hi”? I can start a conversation with anyone, wither i like it or not. But keeping up the conversation is what matters to me.
You’re right though, it is a teamwork thing. Any relationship requires work from both sides. I present my work by showing appreciation to my friends, and so far it seems like it’s working in lowering their anxiety and over thinking :)
Honestly, if the service respects my privacy and isn’t littered with ads, I don’t mind paying at all. Like I wouldn’t mind paying a monthly fee for services provided by Proton, for example, for email, online storage, vpn, etc. I think it’s fair. There’s a lot of infrastructure behind it and employees. Things don’t just run by themselves for free.
But when I pay for a subscription and they publish ads as well for extra income, not only does it make my experience unpleasant, but it’s incredibly greedy. And when I get charged for a service that exploits all my private data to create a user profile that can be sold and used to push targeted ads and other fake information with the goal of changing my opinion on important democratic topics, then that’s when I start completely avoiding that service altogether.
I remember when my mom had a phone with a removable battery, she would drop it a lot and it would separate into a gazillion components but it wouldn’t break. I miss the days
I feel like the parts separating had a lot to do with saving the phone as a whole. It must be absorbing and dissipating some of that energy from the fall rather than all that energy being directed into the phone when it stays together.
I remember my old phones would fly apart from a fall but they’d never suffer any meaningful damage.
Yeah, I think that combined with the explodey factor really saved a lot of my mom’s phones back in the day. In the absolute worst case scenario, there’d maybe be a bit of the corner gouged out if she dropped it on the road or something, but that kind of damage doesn’t spread and you don’t end up with glass shards in your finger if you try to use the phone anyway. Now I’ve gotta practically wrap the thing in bubble wrap to keep it working if it drops
When it comes to pronunciations of obscure computer acronyms, my favourite is btrfs (the filesystem), because I’ve never seen anyone advocate for any specific pronunciation, not even the devs/official documentation. Bee Tree Eff Ess? Bee Tee Arr Eff Ess? Butter Eff Ess? Better Eff Ess? Whatever bloats your goat!
