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.
First: Find easier comprehensible input material. The whole point is to learn new words by guessing their meaning based on context. It aint gonna work if you don’t know enough words to even understand the context. So, content meant for natives will be quite far along your journey. Start first with comprehensible input content meant for learners. And if even that is too difficult, go back to studying the words and grammatical structures that your textbook tells you to.
Second: At least in my experience, there’s no easy way around doing a shitton of flashcard/sentence mining. Set aside time in your weekly (preferably daily) routine to just spam the fuck out of Anki / q*izlet / whatever other app you use and commit to it religiously. Practice makes perfect. Don’t slack off and tell yourself that you’re “not motivated”. Force yourself to study even if you don’t want to. Motivation is a finite resource, Discipline is renewable. Soon enough, you will find that it gets easier and easier to stay motivated. That is the essence of discipline. And, as a bonus, discipline is a universal skill: if you get better at motivating yourself in the context of learning a new language, you will also notice improvements in other areas of your life. Many people start learning a foreign language specifically to train their discipline.
Third: Only do n+1 sentence mining. That means, only make flash cards out of sentences that have only one word or construct that you don’t already know. And if most of the sentences you encounter have more than that, it’s a sign that you have to take a step back and learn the basic vocab sets that your textbook gives you before moving on to comprehensible input and sentence mining.
Fourth: As Stephen Covey said, take time to sharpen the saw. That means put some effort into researching different learning techniques that work for you. Otherwise, you’ll just be wasting time on ineffective strategies. The previous advice I gave may not apply to you specifically, so it’s best to do your own research.
This is some boomer nonsense. I can’t find 2 sources that seem to agree on specific numbers, but several sources, and my personal experience, agree that gas prices peaked in 2008 after the one two punch of Katrina and the housing market collapse
I started driving in 2006 and bought my first car in 2008 and I can confidently say that I’m paying less for gas now than I was when I started driving and I’m not even talking about adjusting for inflation. Are prices too high? Yeah, probably. But this “then vs now” shit just ain’t true
Fair. But isn’t complaining about gas prices America’s largest export?
Just checked some other countries and it seems like Canada is the only one that breaks this general pattern, though it’s obviously not rigorous research
Edit: Also, I don’t really care. I was just venting some frustration to The Internet
The fed subsidizes the shit out of our fuel because the car industry is lobbying it to because the car industry knows that if Americans pay what the rest of the modern world does for gas, then chugga chugga choo choo motherfuckers, we’re finally building some goddamned trains.
That, or they won’t get to sell their huge, overly marked up trucks to middle class suburbanites anymore.
Either of those things would be good for everyone.
I’d also support regulation that bans modifying the ride height of a vehicle. All bumpers should align as a factory spec. We made 70s cars ugly because they required 5 mph bumpers, but we won’t tell Cletus he can’t make his truck bumper sit at neck level so that he doesn’t wipe out a family of four in a Toyota Corolla when he blows through a red light? Horseshit.
I can confidently say the cheapest price I ever saw gas was in 2008. Gas is currently twice as much as that, and two years ago it was almost 4 times as much.
Pretty sure you’d have seen a shit show for anyone who chose not to sign. Especially in like 5th grade when you got this stuff. Most 10 years olds are scared shitless by cops.
Meh, seems to be both. Don’t get me wrong, alcohol is way worse overall. But in my experience the biggest gateway drug to harder stuff is music festivals and learned household behavior from kids in shitty situations.
So funny story about that, because I decided I hated going to school I went to an “alternate” high school that was also where kids who were kicked out of traditional school went.
They’d be like “you get this candy bar if you pledge not to do drugs or drink underage!” And some teens would straight up say “nah I’m good” and I just appreciate the honesty of those kids.
The only people who have offered me drugs are friends who were offering to be polite. I always decline, but use the phrase “No thank you” to let them know I appreciate the gesture.
Yeah they were right about shit like heroin and meth, I knew enough people who threw their lives away to that shit. But my stoner friends were successful and chill. It’s the only drug I care for. I know about benefits of psychedelics but it isn’t for me.
I was one of the very small number of children that bought that bullshit, that all drugs are bad and what have you, but even I thought signing that pledge was kinda fucked up. Like you were required to sign it, we didn’t have a choice.
