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.

Well we'd lose the tides, which would devastate ocean life. We'd lose moonlight, which would devastate nocturnal animals. The axial tilt would change, so seasons would become more even, devastating plants that rely on seasonal cycles, or become more extreme, devastating everything.
The book Seveneves explores this scenario, but is mostly about how humanity moves to space to survive.
Could it even completely obliterate the moon? Just not being tidally locked would be awful, but completely changing its trajectory/orbit and probably fuck up our atmosphere with debris seems more likely
It's probably not big enough to shatter the moon, but enough to at least alter its orbit. I'm not enough of an astrophysicist to say how much. I haven't looked up the forces involved, so I can't even give a ballpark estimate.
It technically would alter the moons orbit, but not by a lot. This asteroid would impact with roughly the energy of a nuclear bomb, which sounds like a lot, but on the scale of our moon it's negligible.
A rough estimation given my limited understanding of physics is that to change the moon's orbit by 1 m/s, you would need to impart something like 10²² joules of energy into it. Wikipedia says that if this asteroid hits the moon, the impact energy will be around 10¹⁶ joules. I don't know how much you know about exponents, but 10¹⁶ is approximately 0% of the way to 10²², and that's just change of 1 m/s
Of course, someone who actually understands physics is free to correct me if I'm wrong
