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.

Wouldn't be a bad idea to do space mining to create products on earth on the long therm?

Does not hose minerals have weight and could change earth net mass and therefore it's orbit?

Could also impacts on landing alter earth orbit?

This question arraised when reading this other question about mining in space from in this sub: [https://lemmy.world/post/24125154](What is currently holding us back from mining in space?)

The earth gains somewhere between 40,000 and 100,000 tons every year, just naturally due to space debris. But I've also read that that's offset by atmospheric gasses leaving the atmosphere, so the earth is actually losing mass.

But there's also the question of how much of that mass entering or leaving is actually affecting the system mass. Any additional mass entering orbit of the earth and moon should affect the earth's orbit as well.

And then, there's the "slingshot" effect where items traveling /with/ the earth's orbit can steal orbital speed from the earth, or when traveling /against/ the earth's orbit can add orbital speed to the earth.

So, the answer is: it's complicated.

I personally don't think it's much to worry about. Before we add enough mass to the earth to affect the orbit, I think we might notice a gravitational change.

Anything you do in space will alter the Earth's orbit by some amount. But unless you strip mine an small planet out there, you won't get enough material for the change to matter.

I guess it could alter earths orbit when you reach a mining contingency that isn't comparable 0 to Earths Mass of 5,9722x10^24^kg

Makes me wonder how much mass we’ve lost to space with all of the shit we’ve flown to and let in space.

[–] ptz@dubvee.org 5 points 4 days ago

how much mass we’ve lost to space with all of the shit we’ve flown to and let in space.

Shooting from the hip here, but probably a tiny, minuscule fraction of a fraction of a percent. I'd venture a guess we've lost more mass in atmospheric gases being ionized and stripped away from solar radiation than we have launched from the surface.

~~Short answer is probably likely:~~

~~Humans are pumping out so much groundwater that it's changing Earth's tilt~~

~~> "Earth's rotational pole actually changes a lot," Ki-Weon Seo, a geophysicist at Seoul National University who led the study, said in a statement. "Our study shows that among climate-related causes, the redistribution of groundwater actually has the largest impact on the drift of the rotational pole."~~

I wouldn't say likely without some revolutionary new propulsion device. We can pump water out of the ground fairly easily but transporting material through space and then landing on the planet is still in science fiction territory.

oh derp

thanks for commenting! Reading the post again my initial answer is real stupid😬

[–] sxan@midwest.social 0 points 4 days ago

Overthinking. Just mine a bunch of iron, or gold, or whatever you can get and drop it in big chunks right on the planet. Don't bother trying to land the stuff. Aim for Mar A Lago. Then drive in and surface mine the payload.

Well that sounds like an inconvenient truth that we should ignore for 100 years until it becomes a seemingly insurmountable problem so we can just shrug our shoulders and say there is nothing that can be done.
