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.

No selection pressure after the age at which our adult teeth fail
This concept can be scaled up to a lot of things, like why most of our systems break down. Nature only maintains what is needed to continue the species, everything that happens to you afterwards, with the exception of child-rearing, will be abandoned by nature unless someone gains some trait from living longer that helps the species propagate.
But nature is kind of silly, it doesn't make "choices" so some of the adaptations can be weird. Like how our retina's blood supply formed on the front of the retina so your brain has to always edit out your blood vessels from your vision and you can only see it using special tricks of light and then BAM all the spaghetti appears that's been there all along.
Imagine what else our brain tells us and shows or doesn't show us to make sense of what evolution has turned us into.
Do you have any resources for the eye spaghetti? That sounds cool
The idea is that if you can make your surroundings as dark as possible, then shine a very small point of light into your eye and wiggle it so there's a shadow changing angles rapidly across your retina, this will make the blood vessels you can't normally see shift slightly in your field of vision so your brain forgets how to edit them out and they pop into view.
This site gives instructions how to use black construction paper with a pinhole in a dark room, but I've learned how to do it with a nearly closed fist and any bright light source.
So its kinda like how your brain edits your nose out but if you close and open alternate eyes fast it has a hard time doing that?
Yep! Or even how you usually breath without thinking about it but can take over manual control. Your brain does a LOT of things with your senses all the time that you don't notice, it has layers and layers of intelligence that makes decisions on what it will "report" upwards, so you depend on basically a vast system of managers or sub-officers that are conscious but have no language, to fully captain and control your meat-ship.
Meat ship is my new band name
X-Men 97 recently gave me "Inferior Freak Fluids" for a good band name. Maybe we can open for you, once I learn how to play.
Hell yeah brother
