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.

So does the sun just have huge amounts of helium? Where is it getting all that helium? Can we have some
It's making it, from the tons of hydrogen it has in the fusion process. The energy and the reason stars even do this is because all of that mass that close together spontaneously does that; starts fusing.
We can't have any, because a star will use up all the hydrogen to make helium, then start using all of the helium to make carbon and oxygen. Then start to make...
This is overly simplified and it varies from star to star (the more massive the star, the longer it churns through "making" elements into more "complex" elements) until its core is all iron, at which point fusion becomes a net negative.
From there other things can happen like novae. All throughout this life process though, that "elemental conversion" is happening faster on the outside as opposed to the core, and stellar winds do blow off heavier elements that enrich the interstellar medium.
We need a shovel that can plunge into the sun's core if we want its helium, TL;DR.
Our sun will stop at carbon, then hang around until it either becomes a brown dwarf, or flies through enough matter to his the Chandrasekhar limit, then KABOOM!
That would be cool to watch
You want to know what would have been really cool to watch?
If you are really patient, I think the sun will inevitably give us a whole bunch of helium.
But not too patient, or else it'll make that helium into something else.
