No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

As hinted at in the title, assuming the technology/means existed that could absorb energy fast enough, would it be possible to stop a star from going supernova, effectively "calming" it?

This is for a novel (not exactly a sci-fi one) but I'd like to keep in the realms of "technically possible".

Edit. Thank you to everyone for providing answers and specific thanks to @Solemn@lemmy.dbzer0.com @radix@lemmy.world and @Deestan@lemmy.world for the for the further reading/watching materials that have inspired a narrative solution that is kinda hand-wave-y but should be good enough to hold up to scrutiny until the moment someone with a PhD (or good enough knowledge) takes a closer look at a fictional word with a soft magic system and smashes the big ol' BS button which I think is about as much as fantasy novel writer can ask for.

A requirement for supernova is a star's total mass being above a certain threshold.

If you can imagine some way of siphoning off mass, you could do it.

One imaginable way would be to move the sun (entire system in tow) close to a black hole or larger sun or something to feed off it. This might well be a recipe for causing a bigger mess, but it might be believable. https://m.youtube.com/watch?v=v3y8AIEX_dU

Wormhole is also a scifi magic solution.
