A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !askusa@discuss.online
Reminder: The terms of service apply here too.

This change has been reverted as it caused all high explosives to have the effect of nuclear weapons. The developers apologize for the inconvenience. In compensation, DNA has been given resistance to radiation damage: this reduces the speed of evolution, but prevents cancers from all the nuclear waste caused by the previous patch. As a bonus, humans with low melanin no longer develop skin cancer due to perfectly ordinary sunlight. Sunburn is still a hazard; wear sunscreen!
Yeah that one's on me. I'm still an intern and thought it would be handy. ^^
Always try new features in prod
Wouldn't this mean all matter could easily reach light speed?
Yes, sound is carried in waves of matter. If sound moved at light speed, the.matter must also. Interesting thought of the day, your heartbeat would explode your chest.
Sound waves are pressure waves, so it isn't matter that moves in only one direction. It's matter that moves back and forth. Therefore I assume the wave can propagate faster than the matter moves.
Fun fact:
When two objects collide, the maximum internal propagation speed of the shock wave is limited by the local speed of sound in the material itself, which is typically 2000-6000 meters per second (m/s).
In low earth orbit, satellites move faster than that, around 7000-7700 m/s. So when they collide (at up to twice that amount in closing velocity), the structure of the satellites is moving faster than the resulting internal shock wave. In one case, there was still a signal sent from a satellite a split second AFTER it had smashed through another satellite, because the resulting shock wave hadn't finished destroying it yet.

Holy shit this makes so much sense!
Dammit, now the lips and words on Netflix don't match.
