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.

If we pray to it, do you think it'll deign to hit us?
Unfortunately, it’s only like 350 meters wide.
The big one that took out the dinosaurs was 10 to 15 kilometers.
A 350 meter asteroid would just make a lot of noise and make a little splash if it survived to hit the ocean, or a little hole in the ground if it managed to strike land.
We need to pray for bigger space rocks.
350m is definetely going to make a strong impact.
The Tunguska Asteroid was expected to be 50-60m in width https://en.wikipedia.org/wiki/Tunguska_event
And that released 3 - 50 Megatons of energy. For reference the nukes on Hiroshima and Nagasaki had about 20 kilotons. So about a one thousands of that. The greatest man made explosion, the sowjet Tsar bomb had about 50 Megatons of energy.
A 350m asteroid has about 7 times that length and probably at least three times the diameter. So we are looking at an impact with the mass of at least 50x that, so 150 - 2500 Megatons. If that hits central Europe the immediate blast would probably kill a few hundred million people.
What if I pray for it to hit me, specifically
Hey, no hogging the roid!
I think many of these asteroids are caused by an intergalactic alien game of 'Road Bowling' and aliens just drunkenly throwing asteroids as far as they can while having a laugh at the local bar.
They usually try to avoid planets with intelligent life but we recently fell below the threshold
They got us with the pog, missed us with the slammer.
(I actually have no idea how pogs work)
There's a not so great book called The Killing Star, where aliens that are never described in the book decide for an unknown reason that we need to be destroyed, so they just hurl as many asteroids as they can at our solar system. It worked pretty well.
Not a bad "low-tech" way to destroy a rival civilization in another solar system. A good idea in an otherwise disappointing book.
You might enjoy a similar plotline in the excellent Bobiverse book series. (I don't think it shows up until the second or maybe even third book, so don't go in expecting that immediately.)
Seconding this. Excellent hard science series that spends equal time on both being a nerd and being nerdy.
Just glancing at what those books are about, they sound fun and I'll check them out, thanks. In the case of The Killing Star, that was the plot point that attracted me to it, but the execution was clumsy and the ending was not exactly a cliffhanger, but it didn't feel like a resolution either.
When I was done reading it, my dog decided it needed to be chewed up. It was the only time she ever chewed up a book. I guess she felt even more strongly about it than I did.
Yeah, I know that kind of book you mean. It's not a popular opinion, but I felt similarly about Annihilation (though I only read the first book of the series, so maybe things would have improved later).
It was aliens. The asteroids are a cover for the fight they had with us today.
So, yes. I think the 'asteroid' would grant this request. But you'd have to get the message channeled through a psychic, and frankly, I don't trust them much.
I’m from Buenos Aires and I say kill them all!
It must be Apophis! Tries to keep the peace treaty with the Asgards by making our extinction seem like a natural disaster!
