No Stupid Questions
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. This includes using AI responses and summaries.

I think I read somewhere that we do have the technology to create a Dyson sphere but it would be too much of a massive undertaking time and labor-wise at our current level.
We have the technology to manufacture materials that could make up a Dyson Swarm. We are not even close to having the technology to make materials that would be sufficient to make a Dyson Sphere.
What we don't have is the resources, logistics, energy supply and manufacturing base to implement either...
We do not. We canβt even move solar energy from earth orbit down to earth at any scale that would be economically viable or really even useful.
We lack the material science to build something that large but still light enough to be physically stable AND somehow collect and transmit energy.
We also lack the technology to stop it from being destroyed by space debris even if we could somehow build it.
There isn't a requirement for a Dyson shell to transmit energy. You could just envelope the sun in habitats that use the energy they collect locally and that would meet the criteria of a Dyson shell (and a K2 civilization).
Sure but that's even harder!
It requires more material and financial resources, but isn't necessarily harder. Transmitting energy effectively to reduce heat, or managing the excess heat starts running into some pretty tough limits of physics. Most of the issues with spinning habitats are engineering problems within the capabilities of our current technology level and materials science. It's just super expensive and has terrible ROI for now.
Not Dyson sphere (also a sphere is literally impossible), though maybe space elevator. If we weren't already so close to Kessler Syndrome, anyways...
