World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Yes in the same way you can “survive” in the vacuum of space. The moon doesn’t have the gravity potential to hold an atmosphere, so while smog may “appear” it’s be gone just like the person who was alive in the vacuum of space for a few minutes as well.
But that doesn’t mean people can and should claim People can live in the vacuum of space now does it?
I really don't understand what you are trying to say here. Yes, the process of diffusion is faster on the moon, but even on earth every second lighter parts of the atmosphere escapes into space (and heavier particles that pass by are attracted by gravity).
It’s not faster on the moon, there’s no restriction because of the lack of atmosphere.
You need gravity for an atmosphere, and you need an atmosphere to hold other particles. Without both, you CANT have “smog”.
Edit, your line of reasoning isn’t that you think it’s possible to terraform the moon or something is it?
But the moon has its own gravity field. Just not enough to keep a permanent atmosphere. Also, not having an atmosphere doesn't mean the space above the surface is devoid of matter. In fact, even in interstellar space, you can find particles. And an atmosphere is not something that's holding particles in. An atmosphere is made up of particles in a dense field gravitationally bound to a celestial body.
Not enough to keep ANY atmosphere. This is the part you are hung up on apparently.
Yes nebulae are visible because they are particles spread usually METERS apart, that’s only visible as a cloud THOUSANDS of light years away. If you were in the center of the nebulae it would be invisible from that perspective. Like being on earth and looking at the moon, there wouldn’t be enough density of particles to say, hey there’s “smog” there. Because the particles float away freely, unlike on earth. And they are also helped carried away by solar winds too. Which you know the atmosphere helps prevent on earth on other planetary bodies….
No, I am totally not. You are hung up on the part where you think that for something resembling smoke to exist, an atmosphere is necessary. Have you never seen RCS thruster being fired in zero gravity?
Yes, there won't be fields of funnels causing smoke clouds that block the view from Earth. But exhaust products being expelled into the vacuum causing measurable dimming effects? Certainly at some point.
I don't get what you're missing here. An atmosphere is the trapping of gasses, the moon doesn't have enough gravity, they will disperse into space very quickly. It's why the ISS doesn't have it's own atmosphere and if they pumped out smoke from that thing it would drift into space, not from a smog cloud around them.
If you have shown anything on this thread is that you are unfamiliar with all the topics you've brushed past.
…. A particle ejected VS Smog… don’t you notice how engines don’t produce smoke in space…? That’s the comparison you should be making.
Using an RCS on earth would look the exact same, other than particles would stick around instead of as you can plainly see in the video, its bursts are IMMEDIATELY gone.
You’re comparing an apple to a piece of steel now, they’re totally different situations and particles.
Engines in space don't produce visible smoke because A) they are precision engineered to burn 100% of the fuel they are supplied with, and what is colloquially known as smoke is unburned particles. All this awesome smoke that engulfs rockets before they take off? Most of it is vapour from water under the platform, protecting the structure from melting. B) Thrusters in general are build to expel the reaction mass as fast as possible in order to go as fast as possible with the least amount of fuel.
So yeah, you are trying to compare what happens in a cars' engine with what's going on in the exhaust: It's the same stuff but under very different circumstances.
